Another post about AA issues

Hi all, after trawling through dozens of similar posts on this sub, I decided to make my own since none of them helped. BYD Han A few days ago, my Android Auto stopped working. The Bluetooth connected, and my phone showed the "Please proceed to Android Auto on your car screen" message. The car also showed the phone as connected via Bluetooth. But Android Auto said "Attempting to start Android Auto with *phone*" a few times, and then showed a message saying "Android Auto failed to start. Please disable Wifi and Bluetooth on your phone and car and try again." So here's what I tried: 1. Restarting the head unit by holding down the volume button. It restarted, but didn't fix the issue. 2. Deleting the car and phone from each other's Bluetooth lists and re-adding, didn't work. 3. Cleared data and cache on Android Auto on my phone, didn't work. 4. I never used wired AA, but I tried that too. Plugged the phone into every USB port in the car (with a tested data-carrying cable) it did nothing. Not even a message popped up indicating that AA was available, it just started charging and nothing else. I couldn't find Android Auto on the apps list on the head unit to try and clear its cache. And now I'm out of ideas. Any of you guys have any ideas?

Delete cache from aa on your phone. Your phone is the brains not the car. Beware when clearing cache + data it will reset AA so you can configure it again when connecting a car to AA

So delete just cache but not data? Pretty sure I tried that, but I'll try it again ig

I would do cache and data just to be sure!

Just tried both, didn't work : ( I guess the only thing I have left to try is factory resetting the head unit

Are you using a VPN or similar privacy tools?

Nope. Even if I did, the phone actually tells me to turn it off for AA to work lol, I know because I tried before. But nah, this is something else.

I would try troubleshoot by borrowing another android phone and seeing if android auto works. If it works, then its likely your phone thats the issue. If it doesn't, then its likely the car thats the issue. It might not solve the problem, but you might better understand as to wether you need to go to the BYD or phone shop.
