Symptoms
- Phone doesn't launch Android Auto when plugged in
- App shows an error or gets stuck loading
- Works with some cables but not others
- Was working before a phone or app update
Likely causes
- CommonFaulty or charge-only USB cableSome cables can charge a phone but don't support the data transfer Android Auto needs.
- CommonAndroid Auto app needs updating or cache clearingApp bugs are common after phone OS updates and often need a fresh cache or update to fix.
- PossibleUSB debugging or developer settings interferingCertain developer options can block or change how Android Auto connects.
- PossibleDirty or damaged USB port on phone or carDebris in either port can prevent a stable data connection.
What to do
- Try a different USB cable, preferably the one that came with your phone.
- Clean both the car's USB port and the phone's charging port of any lint or debris.
- On the phone, open the Android Auto app, go to settings, and clear the cache, or update the app from the app store.
- Restart the phone and the car, then reconnect.
- Check developer options on the phone (if enabled) to ensure USB configuration is set to allow file transfer or Android Auto's required mode.
- If wireless Android Auto is supported by your car and phone, try that instead to rule out a cable-specific issue.
Tools and parts
- Compressed air or soft brush for port cleaning

When to call a pro
If a good cable and updated app still won't connect, have the dealer check the car's USB module for a known issue.
