I just got a vehicle that supports it, but when my Pixel 3 tries to connect, the AA UI shows briefly for a second, then fails, every time. Any tips? I've tried over USB and wireless, same result.
Not the parent but in my ‘18 Audi I think I called the dealer and they did some kind of software update which resolved the issue.
Mines wired only but my issue seemed to be cable related. I bought an anker powerline II usb c to a cable based on reddits recommendation and haven't had any issues since!
I've certainly seen issues with cables before (even ones that seem to half work), as mentioned in another reply. My first step in debugging would be to unpair the devices (on both sides) and try to set them up again to see if that helps.
Might have to go to a dealer to get a firmware upgrade.
