Android Auto not working can mean several different things. Your phone may charge without Android Auto appearing, the car may not detect the phone, wireless Android Auto may refuse to connect, the dashboard may show a black screen, or individual features such as Maps, calls, audio, and voice commands may fail even though the main interface opens.
The right fix depends on where the connection breaks.
Start by identifying whether you use wired or wireless Android Auto and whether the problem affects the entire connection or only one feature. A wired connection points first to the USB cable, USB port, and vehicle projection settings. A wireless failure points more strongly to Bluetooth, Wi-Fi, saved pairing data, wireless compatibility, or the infotainment system.
Google currently says Android Auto is integrated into supported Android phones rather than requiring a separate standalone app installation. Google also lists Android 9.0 or later, a compatible vehicle or aftermarket receiver, and a suitable connection as core requirements.
Before changing advanced phone settings, park the vehicle safely. Do not troubleshoot menus or handle cables while driving.
First, Identify What “Android Auto Not Working” Means
Use the symptom to narrow down the likely cause.
| What you see | Best place to start |
|---|---|
| Phone charges but Android Auto does not open | USB cable, correct car USB port, Android Auto enabled in the head unit |
| Car does not detect the phone | Compatibility, cable, USB port, saved car connection |
| Wireless Android Auto does not connect | Wi-Fi, Bluetooth, wireless compatibility, re-pairing |
| Android Auto opens and then disconnects | Cable/port for wired, wireless interference/pairing for wireless |
| Black screen on the car display | Restart infotainment, reconnect phone, update car software |
| Android Auto works but Maps or music does not | Mobile data, app update, app permissions |
| Calls work but Android Auto does not appear | Ordinary Bluetooth may be connected without Android Auto projection |
| Android Auto stopped after an update | Restart, update Android Auto/Android again, recreate the car connection |
| One phone works but another does not | Focus on the failing phone |
| No phone works in the same car | Focus on the car, USB port, receiver, or infotainment firmware |
This distinction matters because Android Auto is a connection between two systems: the Android phone and the vehicle display. Resetting the phone repeatedly will not fix an unsupported car, damaged USB socket, or broken head unit.
1. Confirm That the Car Actually Supports Android Auto
A USB port in a vehicle does not automatically mean Android Auto is supported.
Google states that the car must support Android Auto or use a compatible aftermarket receiver.
Check:
- Vehicle make, model, year, and trim
- Owner’s manual
- Manufacturer’s infotainment documentation
- Whether Android Auto is included on that specific head unit
- Whether the car supports wired Android Auto, wireless Android Auto, or both
Some vehicles support only wired Android Auto even though they also have Bluetooth.
Others support wireless Android Auto only on certain trims or model years.
If you recently changed cars, do not assume the new vehicle supports the same connection type as the old one.
For a broader comparison of the two major phone-projection platforms, see Apple CarPlay vs Android Auto.
2. Make Sure Android Auto Is Enabled in the Car
Android Auto can be disabled inside the vehicle’s infotainment settings.
Google specifically recommends confirming that Android Auto is turned on in the car.
Look for menu names such as:
- Android Auto
- Smartphone Projection
- Phone Projection
- Projection Manager
- Device Connections
- Connected Devices
- Smartphone Integration
Enable Android Auto for your phone.
Some head units also let you disable Android Auto for an individual saved device while ordinary Bluetooth calls remain enabled.
If the phone connects for calls and music but the Android Auto icon never appears, check this setting before resetting the phone.
3. Restart the Phone and the Infotainment System
Restart both sides of the connection.
First restart the Android phone.
Then restart the car’s infotainment system using the vehicle manufacturer’s normal procedure.
On some vehicles, simply turning the ignition off does not immediately shut the infotainment computer down. It may remain active for several minutes.
If your manufacturer provides a dedicated head-unit restart method, use it.
Google specifically recommends restarting the infotainment system when Android Auto is not working.
After both devices restart:
- Unlock the phone.
- Start the vehicle while parked.
- Wait for the infotainment system to finish loading.
- Connect Android Auto again.
Test before changing more settings.
4. Replace the USB Cable for Wired Android Auto
A bad USB cable is one of the first things Google tells users to check.
A phone can charge normally through a cable while Android Auto fails because charging and data transfer do not depend on exactly the same connection quality.
Google currently recommends:
- A high-quality USB cable
- A cable under 3 feet or 1 meter where possible
- No USB hub
- No cable extension
- Trying the cable supplied with the phone when compatible
Use a known-good data-capable cable, not a cable designed only for charging.
Replace the cable immediately when you notice:
- Android Auto appears only when the cable is held at an angle
- The connection drops when the phone moves
- The phone charges but the dashboard never recognizes Android Auto
- Android Auto repeatedly connects and disconnects
- The cable feels loose at either end
Do not judge the cable only by whether it charges the battery.
If Android Auto already starts but repeatedly drops during the drive, use my dedicated Android Auto Keeps Disconnecting guide. It separates recurring wired and wireless disconnections in much more detail.
5. Use the Correct USB Port in the Vehicle
Many cars have several USB ports, but only one may support Android Auto.
Other ports may be intended for:
- Charging
- USB drives
- Rear passengers
- Media playback
- Service use
Look for a phone, projection, USB, or Android Auto symbol near the correct port.
Check the owner’s manual if the labeling is unclear.
Connect the phone directly to the approved port.
Avoid:
- USB hubs
- Extension cables
- Splitters
- Magnetic adapters
- Multi-port adapters
- Unnecessary converters
If one vehicle port fails but another Android Auto-capable port works, the original port may be damaged or configured differently.
6. Check the Phone’s USB Port
Pocket lint and debris can prevent a USB plug from seating fully.
The phone may still charge because the power connection survives while the data connection becomes intermittent.
Turn the phone off and inspect the port under good light.
Look for:
- Pocket lint
- Dust
- Bent contacts
- Corrosion
- Moisture
- A connector that no longer fits firmly
Remove only loose debris using a safe, dry, non-metallic method.
Do not insert a needle or metal pin into the charging port.
Do not pour cleaning liquid into it.
A port that is loose, corroded, damaged, or affected by a moisture warning may require professional repair.
7. Unlock the Phone and Accept the Setup Prompts
The first Android Auto connection may require several permissions and confirmations.
With the vehicle parked:
- Unlock the Android phone.
- Connect it to the car.
- Watch both the phone and dashboard.
- Accept the Android Auto setup prompts.
- Grant the permissions needed for the features you want to use.
- Complete any Bluetooth pairing request that appears.
Google notes that the phone may ask you to update Android Auto during setup.
Do not repeatedly dismiss setup prompts and expect the dashboard interface to initialize normally.
8. Fix Wireless Android Auto Not Working
Wireless Android Auto has more connection layers than a USB connection.
Google’s current setup instructions say the first wireless connection requires pairing the phone and car through Bluetooth. Google also recommends keeping Bluetooth, Wi-Fi, and Location Services turned on while completing wireless setup.
Before troubleshooting anything deeper:
- Turn Bluetooth on.
- Turn Wi-Fi on.
- Turn Location on.
- Make sure mobile data is available.
- Confirm that the vehicle specifically supports wireless Android Auto.
- Put the vehicle into its wireless phone-pairing mode.
- Pair the phone from Bluetooth settings.
- Follow the dashboard prompts.
A car can support wired Android Auto without supporting the wireless version.
Ordinary Bluetooth connectivity is also not proof that wireless Android Auto should work. Bluetooth can handle calls and audio in cars that do not support wireless Android Auto projection.
9. Forget the Car and Pair It Again
A saved Android Auto or Bluetooth profile can become corrupted after an Android update, vehicle update, phone migration, or repeated failed setup attempts.
Google specifically recommends forgetting previously connected cars when connection problems occur.
On many Android phones:
- Open Settings.
- Search for Android Auto.
- Open Previously connected cars.
- Remove the affected vehicle or choose Forget all cars when appropriate.
Then remove the Bluetooth pairing:
- Open Settings > Connected devices or Bluetooth.
- Select the vehicle.
- Tap Forget or Unpair.
Finally, delete the phone from the vehicle’s saved-device list.
Restart both systems and pair them again from scratch.
This is more effective than repeatedly tapping Connect on a damaged saved profile.
10. Remove Old Phones From the Vehicle
Some cars prioritize one saved phone over another.
Android Auto may appear unreliable when another family member’s phone connects first.
While troubleshooting:
- Turn Bluetooth off on other phones in the vehicle.
- Remove unused phones from the car’s device list.
- Set your phone as the primary device if the head unit offers that option.
- Reconnect only one phone until Android Auto works consistently.
If the problem appears only when another phone enters the car, device priority is a strong clue.
11. Update Android Auto and Android
Android Auto is integrated into current supported Android phones, but Android Auto components can still receive updates through Google Play.
Open the Play Store and search for Android Auto.
Install an update if one is offered.
Also update:
- Android
- Google Maps
- Google app
- Music or podcast apps you use in Android Auto
- Google Play system components where updates are available
For Android itself, the exact path varies by manufacturer but is commonly:
Settings > System > Software update
Samsung commonly uses:
Settings > Software update > Download and install
Restart after installing updates.
Do not download unofficial Android Auto APK files from random websites to solve a connection problem.
12. Update the Vehicle’s Infotainment Software
Android Auto does not run entirely on the phone.
The head unit also has firmware that can contain compatibility bugs.
Google specifically recommends checking for receiver firmware updates when using an aftermarket unit such as Pioneer or Kenwood.
For factory infotainment systems, check:
- Vehicle Settings
- Manufacturer’s owner portal
- Official vehicle app
- Dealer service information
- Manufacturer support page
Install only firmware designed for the exact vehicle or receiver.
Do not interrupt an infotainment firmware update, because a failed installation can disable more than Android Auto.
13. Check Android Auto Permissions
A permission problem may break Android Auto completely or disable only certain features.
Open:
Settings > Apps > Android Auto > Permissions
Review the permissions needed for the features you use.
Depending on Android version and phone manufacturer, these can include access related to:
- Phone
- Contacts
- Microphone
- Notifications
- Nearby devices
- Location
If Android Auto itself opens but one function fails, check the permission for the affected app too.
Examples:
- Google Maps needs location access.
- Calling features need phone-related permissions.
- Voice interaction needs microphone access.
- Messaging features may depend on notifications.
Do not grant unrelated permissions to random third-party apps in an attempt to repair Android Auto.
14. Clear the Android Auto Cache
Corrupted temporary data can interfere with launching or pairing.
On many phones:
- Open Settings > Apps.
- Select Android Auto.
- Tap Storage & cache.
- Choose Clear cache.
- Restart the phone.
- Reconnect to the vehicle.
Clearing cache is less disruptive than clearing storage.
If the problem remains, Clear storage or Clear data can be considered, but that may reset Android Auto preferences and saved connection information.
You may need to set the car up again.
15. Check Battery Restrictions
Some Android manufacturers aggressively limit background activity.
That can affect apps needed during Android Auto sessions, particularly when the problem appears after several minutes rather than immediately.
Open:
Settings > Apps > Android Auto > Battery
Look for an option such as:
- Unrestricted
- Not optimized
- Allow background activity
The wording varies by phone.
On Samsung Galaxy phones, also check:
Settings > Battery > Background usage limits
Make sure important Android Auto-related apps have not been placed in Sleeping apps or Deep sleeping apps while troubleshooting.
Do not disable every battery protection feature permanently.
Change only the apps that are actually involved and retest.
16. Turn Off Battery Saver Temporarily
Battery Saver can restrict background activity and network behavior.
Turn it off temporarily and test Android Auto again.
If Android Auto starts working normally, review:
- Battery Saver schedule
- App-specific battery restrictions
- Power-saving modes from the phone manufacturer
This is particularly useful when Android Auto works with a full battery but becomes unreliable when the phone enters a power-saving mode.
17. Check Mobile Data When Maps, Music, or Voice Features Fail
A broken internet connection can look like an Android Auto problem even when the dashboard projection itself is still working.
For example:
- Android Auto remains visible
- Google Maps cannot load traffic or destinations
- Streaming music stops
- Voice requests fail
- Online searches do not work
Disconnect from the car and test mobile internet directly on the phone.
If cellular data itself is failing, use Mobile Data Not Working on Android to fix the underlying connection rather than repeatedly resetting Android Auto.
Android Auto can still display some local interface elements without a healthy internet connection, so separate an internet failure from a projection failure.
18. Turn Off Personal Hotspot During Wireless Testing
Wireless Android Auto uses the phone’s wireless radios, so another active wireless feature can complicate diagnosis.
Turn off the phone’s hotspot temporarily:
Settings > Network & internet > Hotspot & tethering
or the equivalent path on your device.
Reconnect Android Auto.
If Android Auto begins working normally, retest before deciding whether the hotspot was actually responsible.
If the hotspot itself has become unreliable, see Android Hotspot Not Working rather than mixing the two problems together.
19. Disable a VPN Temporarily
A VPN usually affects internet traffic rather than the basic Android Auto projection connection, but VPN, firewall, Private DNS, or network-filtering software can interfere with online Android Auto features and sometimes complicate wireless setup.
Temporarily disconnect a personal VPN and test again.
If Android Auto starts working:
- Update the VPN app.
- Review local-network permissions if available.
- Check split-tunneling settings.
- Contact the VPN provider if necessary.
Do not remove an employer-managed VPN without permission.
20. Fix Android Auto Not Working After an Android Update
An Android or One UI update can coincide with Android Auto connection problems.
Do not immediately factory-reset the phone.
Use this order:
- Restart the phone.
- Restart the infotainment system.
- Check for another Android update.
- Update Android Auto through Google Play.
- Update Google Play system components if available.
- Forget the car.
- Remove the Bluetooth pairing.
- Delete the phone from the car.
- Pair everything again.
- Clear Android Auto cache if needed.
When the problem begins directly after a system update, the saved relationship between phone and car is often worth rebuilding before more destructive troubleshooting.
21. Fix Android Auto Not Working on Samsung Galaxy
Samsung Galaxy phones use the same Android Auto platform, but One UI adds its own battery and connection controls.
Start with the normal fixes above.
Then check:
Settings > Battery > Background usage limits
Make sure the apps you need have not been placed in Deep sleeping apps.
Also check:
Settings > Software update > Download and install
If Bluetooth and Wi-Fi pairing remain corrupted after the simpler fixes, Samsung provides a network settings reset. This is more disruptive because saved network information can be removed, so use my Reset Network Settings on Samsung guide before doing it.
Do not reset network settings simply because one USB cable fails.
22. Fix Android Auto Black Screen
A black car display is different from the phone not being detected.
If Android Auto connects but the display remains black:
- Disconnect the phone.
- Restart the phone.
- Restart the infotainment system.
- Reconnect.
- Try another high-quality USB cable if wired.
- Recreate the wireless pairing if wireless.
- Update Android Auto.
- Check for vehicle infotainment firmware updates.
If the entire head unit freezes or restarts, the problem may be on the vehicle side rather than Android Auto itself.
Try another compatible phone.
If both phones create the same black screen, focus on the vehicle or receiver.
23. Fix Android Auto Phone Charges but Does Not Connect
This symptom strongly points toward the wired data path.
Charging alone proves that power reaches the phone. It does not prove that USB data transfer is working.
Try:
- A different high-quality data cable.
- A cable under 1 meter where practical.
- The correct Android Auto USB port.
- No USB hub or extension.
- Cleaning the phone’s USB port.
- Another compatible phone in the same car.
- Another Android Auto-capable USB port if the vehicle provides one.
When a second phone works with the same car and cable, focus on the original phone.
When neither phone works, focus more strongly on the cable, USB socket, or infotainment system.
24. Fix Android Auto Not Detecting the Phone
When the car does not recognize the phone at all, check the basics in this order:
- Confirm Android Auto compatibility.
- Confirm Android Auto is enabled in the head unit.
- Restart phone and infotainment.
- Replace the USB cable if wired.
- Use the correct USB port.
- Unlock the phone.
- Accept setup prompts.
- Forget previously connected cars.
- Remove Bluetooth pairing.
- Delete the phone from the vehicle.
- Pair again.
If another compatible Android phone works immediately, the vehicle is less likely to be the root cause.
25. Fix Android Auto Not Connecting Wirelessly but Wired Works
This is an important diagnostic result.
A working wired connection proves that:
- The phone can run Android Auto.
- The vehicle can display Android Auto.
- Basic app compatibility is present.
Focus on the wireless layer:
- Verify the vehicle supports wireless Android Auto, not only wired.
- Turn on Wi-Fi.
- Turn on Bluetooth.
- Turn on Location during setup.
- Forget and recreate the connection.
- Remove competing saved phones.
- Restart the head unit.
- Disable hotspot during testing.
- Check for wireless interference.
- Update the car’s firmware.
Do not keep replacing USB cables when the wired connection already works perfectly and only wireless projection fails.
26. Fix Wired Android Auto Not Working but Wireless Works
This points strongly toward the USB connection.
Check:
- Cable
- Correct vehicle USB port
- Phone USB port
- USB adapters or hubs
- Physical looseness
- Debris
- Vehicle port damage
Try another known-good cable first.
If wireless Android Auto remains stable, clearing Android Auto data or factory-resetting the phone is unlikely to be the best first response.
27. Fix Android Auto Audio Not Working
Sometimes Android Auto is connected correctly but you hear no sound.
Check whether the problem affects:
- Music
- Navigation prompts
- Calls
- Every source
Then:
- Raise the vehicle media volume.
- Make sure the car is using the correct audio source.
- Pause and resume the media app.
- Switch to another Android Auto audio app.
- Restart the infotainment system.
- Disconnect unnecessary Bluetooth audio devices.
- Update the affected media app.
A call-audio problem alone is different from Android Auto failing to connect.
Do not clear every Android Auto setting because one music app is muted.
28. Fix Google Maps Not Working in Android Auto
If Android Auto opens but Maps does not work:
- Check mobile data.
- Turn Location on.
- Update Google Maps.
- Check Maps location permission.
- Force stop and reopen Maps.
- Clear the Maps cache if needed.
- Test another navigation app supported by Android Auto.
If every internet-dependent app fails at the same time, test the phone’s mobile data first.
29. Fix Apps Missing From Android Auto
Not every Android app is allowed to appear on the car display.
Open Android Auto settings and look for Customize launcher.
Make sure the supported app is enabled.
Also update the app through Google Play.
Google provides a list of apps designed for Android Auto. Unsupported apps cannot normally be added simply by granting more permissions.
Avoid modified Android Auto tools intended to bypass driving restrictions.
Android Auto is not designed to mirror every phone app to the dashboard. My Android Screen Mirroring guide explains the difference between normal screen mirroring and the approved Android Auto interface.
30. Test Another Phone
This is one of the most valuable diagnosis steps.
Use another Android phone that is known to support Android Auto.
Connect it to the same vehicle.
Second Phone Works
Focus on the original phone:
- Android updates
- Android Auto cache/data
- Saved car profile
- Bluetooth pairing
- Battery settings
- USB port
- Network configuration
Second Phone Also Fails
Focus on:
- Vehicle compatibility
- Infotainment setting
- USB cable
- USB port
- Vehicle firmware
- Aftermarket receiver
This prevents hours of changing phone settings when the real fault is inside the vehicle.
31. Check an Aftermarket Receiver
Android Auto behavior depends heavily on the head unit.
For an aftermarket Pioneer, Kenwood, Sony, Alpine, JVC, or other receiver:
- Confirm the exact model supports Android Auto.
- Check whether it supports wired, wireless, or both.
- Verify the correct USB lead is connected.
- Check the manufacturer’s firmware page.
- Use the receiver’s recommended pairing procedure.
Google specifically recommends checking the receiver manufacturer’s website for firmware updates.
Do not install firmware meant for a similar-looking but different model.
32. Reset Network Settings Only for Wireless Problems That Survive Re-pairing
A network reset is not the first fix for Android Auto.
It removes or resets networking information and can require you to reconnect Wi-Fi and Bluetooth devices.
Consider it only when:
- Wireless Android Auto fails
- Bluetooth pairing behaves abnormally
- Wi-Fi behaves abnormally
- Forgetting and re-pairing the car does not help
- Other network features are also unstable
On Samsung, use the dedicated Reset Network Settings on Samsung instructions so you understand what will change.
For a wired-only failure where another cable fixes the problem, a network reset offers little value.
33. Do Not Factory Reset the Phone Too Early
A factory reset is rarely a sensible early response to Android Auto not working.
Before considering one, you should already know:
- The car is compatible.
- Android Auto is enabled in the car.
- A known-good cable has been tested.
- The correct USB port is being used.
- The car has been forgotten and paired again.
- Android and Android Auto are updated.
- Another phone has been tested.
- Vehicle firmware has been checked.
If another phone also fails in the same car, factory-resetting your phone is particularly unlikely to solve the real problem.
Use manufacturer or Google support before erasing a phone solely for Android Auto.
Android Auto Works but Keeps Disconnecting
A connection that launches successfully and then repeatedly drops is narrower than the broad android auto not working problem.
For wired Android Auto, repeated disconnects usually deserve a close look at:
- Cable
- Phone USB port
- Car USB port
- Movement over bumps
- Heat
For wireless Android Auto, focus more on:
- Wi-Fi
- Bluetooth
- Pairing
- Other phones
- Interference
- Vehicle firmware
I cover those patterns separately in Android Auto Keeps Disconnecting? See How to Fix It so this page does not duplicate an entire disconnect-specific troubleshooting guide.
Android Auto Is Missing From the Phone
On current supported Android phones, Android Auto is integrated into the phone.
Google states that you do not need to install a separate Android Auto app simply to use it with a car display.
Search the phone’s Settings for:
Android Auto
The exact path varies by Android version and manufacturer.
If the setting exists but no normal app icon appears in the launcher, that does not necessarily mean Android Auto is missing.
Does Android Auto Need Bluetooth?
For wireless setup, yes, Bluetooth is part of the initial pairing process.
Google’s current wireless setup instructions tell users to pair the phone and car through Bluetooth and keep Bluetooth, Wi-Fi, and Location Services enabled during setup.
A wired Android Auto session still commonly uses Bluetooth for certain phone functions depending on the vehicle, but the dashboard projection itself is carried through the USB connection.
Does Android Auto Need Wi-Fi?
Wireless Android Auto uses Wi-Fi as part of its wireless connection.
That is why a phone can be connected to the car for ordinary Bluetooth calls while the Android Auto dashboard itself fails to launch.
For wired Android Auto, the projection connection runs through USB instead.
Does Android Auto Need Mobile Data?
Android Auto can display its interface without every feature requiring mobile data at every moment, but online functions depend on internet access.
Mobile data is especially important for:
- Live navigation
- Traffic information
- Streaming
- Online search
- Voice services
- Cloud-based features
When Android Auto stays connected but online features stop, troubleshoot the phone’s internet connection separately.
Frequently Asked Questions
Why is Android Auto not working?
Common causes include an incompatible car, Android Auto being disabled in the head unit, a bad USB cable, the wrong vehicle USB port, corrupted saved pairing data, wireless connection problems, outdated phone or vehicle software, and hardware faults.
Why is my phone charging but Android Auto not working?
Charging only confirms that USB power is reaching the phone. Android Auto also requires a reliable data connection. Try a different high-quality data cable and the vehicle’s correct Android Auto USB port.
Why is Android Auto not connecting to my car?
Confirm that the car supports Android Auto and that Android Auto is enabled in the infotainment system. Then restart both systems, check the cable or wireless setup, forget the saved car, and pair again.
Why did Android Auto suddenly stop working?
A cable can fail, saved pairing information can become corrupted, a phone or vehicle update can change compatibility, or the infotainment system may need a restart. Start with the connection method that was working previously rather than resetting everything.
Why is wireless Android Auto not working?
The car may support only wired Android Auto, or the wireless setup may be failing because of Bluetooth, Wi-Fi, saved pairing data, another phone, wireless interference, or outdated infotainment software.
Why does Bluetooth work but Android Auto does not?
Ordinary Bluetooth calls and music are different from Android Auto projection. A car can pair successfully over Bluetooth even when Android Auto is disabled, unsupported, or unable to complete its USB or Wi-Fi connection.
Can a USB cable stop Android Auto from working?
Yes. Google specifically recommends checking the USB cable and using a high-quality cable. A phone may still charge through a cable that cannot maintain reliable data transfer.
Should I clear Android Auto data?
Clear cache first. Clear storage or data only when simpler steps fail because it can reset preferences and require you to set up the vehicle again.
Should I reset network settings?
Only after simpler wireless troubleshooting such as restarting, forgetting the car, re-pairing Bluetooth, and checking Wi-Fi. A network reset is not a useful first response to a clearly wired USB problem.
Should I factory reset my phone?
Usually not. Test the cable, vehicle, another phone, saved pairing, updates, and infotainment system first. A factory reset should be far down the troubleshooting list.
Find the Failure Before Resetting Everything
Android Auto involves the phone, the connection method, and the vehicle infotainment system. The fastest troubleshooting comes from identifying which of those three is failing.
For wired Android Auto, start with Google’s most practical checks: vehicle compatibility, Android Auto enabled in the car, a short high-quality USB cable, and the correct USB port.
For wireless Android Auto, confirm that the vehicle actually supports wireless projection, then keep Bluetooth, Wi-Fi, and Location enabled during setup and rebuild the pairing if necessary.
When another phone works in the same car, concentrate on your phone. When no compatible phone works, stop repeatedly resetting Android and investigate the vehicle, receiver, cable, port, or infotainment firmware instead.
