The latest update, March 2026, made Android Auto unusable in my car! It was fine before the update, but after, it no longer works. Thought it may be the USB cable but I tried several that I had and even got a new one that is specifically for Android Auto but still won't work. It is a data transfer and charging cable. I'm literally lost without it. My car screen is useless now, I can't connect to it with it not recognizing the cable. Android Auto doesn't work on Bluetooth.
The car doesn't recognize all your contacts? Does the phone recognize them all?
What year is your car? Your head unit software may need an update of its own to accommodate the new update. I had the March update. I have a 2017 car. I have had no problems with either my car's Bluetooth recognition of my phone and its contents or Android Auto connectivity. I understand you and other people are having issues and it's frustrating. But if all your contacts are still recognized by your phone and you are working out of your car, you can just put the phone on speaker and have Google Assistant or Bixby dial your calls hands free.
Have you tried unpairing the phone from your car and removing it from the database and then going through the process again? If the contacts exist on your phone, they should all get downloaded to the car when paired.
Hello @Ostry, Thank you for reaching out to the Community. We can understand how frustrating this issue is for you. You can try unpairing and deleting the phone from the car’s Bluetooth list. Also forget the car from the phone's Bluetooth settings, then restart the phone and pair again. You can also try clearing the Android Auto Cache by going to settings, apps, Android Auto, Storage, then Clear Cache and Data. I hope that this information was able to clear up the issue. Please feel free to let us know if it helped.

I've done ALL of this, new cords, delete cache, restart car head unit, delete data, uninstall updates, reinstall I've done EVERY troubleshooting that's available turned off privacy. Since March android auto is completely unusable. My son has same problem in his car as well. I'm corded he's wireless. It's useless and something needs to get fixed NOW!
I've done all of these things as well and AA still won't work. When I plug in a cord is get this error message "This device does not support media function" I don't know what "device" it's referring to. The phone? I have S24 Ultra. I never had a problem with AA before the March update. I uninstalled AA and reinstalled, it's a different version now so I was hopeful that it would work now but no, it does not.
I have verified it is my phone. I perched a second Android Auto device and it does the same thing. I connect via Bluetooth and it randomly reboots every 3 to 8 minuets.
