For a more reliable Android Auto connection, first confirm that your phone and car support the connection mode you’re using. For wireless setup, keep Bluetooth, Wi-Fi, and Location Services on while pairing. For a wired connection, use a high-quality USB data cable shorter than one metre, plugged directly into the car—without a hub or extension. Then check that Android Auto is enabled in the car’s infotainment system.
Check compatibility before changing settings
A USB port does not by itself mean a car supports Android Auto. Your phone and the car or stereo must both support the connection mode you want to use. Google’s requirements for Android Auto list Android 9.0 (Pie) or later and an active data plan for wired use, along with a compatible car and high-quality USB cable. Android (Go edition) devices are not supported.

Wireless projection has separate requirements: a compatible Android phone with an active data plan and 5 GHz Wi-Fi support, plus a compatible car or stereo. Google recommends asking the phone manufacturer about 5 GHz support and the vehicle maker about compatibility with a particular car or stereo.

Android Auto is integrated into compatible phones for car-display use, so you do not need to download a separate Android Auto app. If you are unsure whether your vehicle supports wired or wireless Android Auto, confirm with its manufacturer.

Set up wireless Android Auto with the right radios on
- Park the car and turn on its infotainment system.
- Make sure the car or stereo supports wireless Android Auto and that your phone meets the applicable requirements.
- Turn on Bluetooth, Wi-Fi, and Location Services on your phone. Google Android Auto Help advises: “For best results, keep your phone’s Bluetooth, Wi-Fi, and Location Services turned on while you complete the setup.”
- Complete the first connection by pairing the phone and car via Bluetooth, following the vehicle’s on-screen instructions.
If wireless setup still fails, revisit compatibility and the vehicle’s setup instructions rather than assuming an unrelated phone setting will fix it. Google’s Android Auto setup guidance covers the connection process; the vehicle manufacturer can confirm model-specific steps.
For a wired connection, check the cable and port
- Confirm that both the phone and car or stereo support wired Android Auto.
- Connect the phone directly to the car’s USB port with a high-quality USB data cable. Trying the cable supplied with the phone is a sensible first check.
- If the connection is unreliable, try a cable shorter than one metre. Remove any USB hub or extension from the connection.
- If a cable that previously worked has stopped connecting, try replacing it.
Google’s cable-length and hub guidance is troubleshooting advice, not a quantified reliability test. It does not establish that a particular cable brand or specification will improve connection reliability.

Check Android Auto in the car’s infotainment settings
Look in the car or stereo’s infotainment settings and make sure Android Auto is enabled. If it is enabled but the phone still will not connect, restart the infotainment system and try again. With an aftermarket receiver, check the receiver manufacturer’s support site for firmware updates and model-specific instructions.

If Android Auto fails when you try to connect to another car, Google recommends clearing the phone’s remembered-car list and setting up the connection again. Its documented menu path is:

Choose the check that matches the symptom
| What you’re seeing | What to check first |
|---|---|
| Wireless setup does not complete | Confirm wireless compatibility; keep Bluetooth, Wi-Fi, and Location Services on; pair the phone and car via Bluetooth. |
| Wired Android Auto disconnects or does not start | Confirm wired compatibility; connect directly with a high-quality data cable under one metre, without a hub or extension. |
| Android Auto is unavailable from the car’s display | Check that Android Auto is enabled in the infotainment settings; restart the system if needed. |
| Connection fails in a second car | Use Google’s documented path to forget previously connected cars, then try setup again. |
When these checks do not resolve the issue, the vehicle or stereo manufacturer is the best source for model-specific compatibility and setup help.
