  • Wired Android Auto - No Bluetooth for Phone Calls

Hey all. Just got a new car ('24 Honda Civic) and am unable to get phone call audio to come through the car speakers when using wired Android Auto. It just says that Bluetooth isn't connected and phone call audio goes through my Pixel 8 speakers. When I connect AA, the Pixel tries to pair via Bluetooth over and over but fails with a little "Invalid PIN" pop-up. I can connect with Bluetooth if I put the car in pairing mode and then phone calls come through the Honda interface. However, as soon as I connect with AA the car disconnects from Bluetooth. It's like there's a different connection for AA vs the Honda interface.

Not sure if this is a GOS issue or if the Honda head unit really is that broken. I don't have a stock Android device to test with. My previous car had an aftermarket head unit and phone calls worked as expected with wired AA. I suspect that wireless AA would probably work fine, but I really don't want to enable all those permissions. I also wonder if it's an AA bug and if there's a newer version with better support. Is there any way to beta test a newer version of AA? I'd be willing to do some testing and provide logs if it would help.

    Ninja4694 I also had Bluetooth problems, but it was with the player. The workaround: activate Bluetooth on the car unit side as well, or stop Bluetooth first and then restart it. Not exactly smooth, is it? You could at least give it a try.

      Had this problem early on. Enable "Wireless AA" in the settings. Not sure why but that solved it.

        Dan-cer Thanks. Yeah I've tried everything like that I can think of. It connects with the car just fine outside of Android Auto but refuses to pair with AA connected.

        5rlyn Thanks. I suspect that would fix it and it would be nice to not worry about using a cable anymore, but allowing Wireless AA grants a lot of permissions to the AA app. This includes the ability to access the network, manage WiFi and Bluetooth at will, etc. I like to keep as many Google apps off the network as possible. However, I do use Google Maps (signed out) anyway, so maybe giving AA network access wouldn't really matter so much. 🤔

          Enabling the Wireless Android Auto permission did work. Would be nice if it wasn't necessary here, but oh well. Glad to have AA working on GrapheneOS regardless. 🙂

          5rlyn I had the exact same issue as OP ('24 Infiniti QX60) and enabling wireless AA resolved the issue for me as well! My car only supports wireless with CarPlay, not AA, but this was the resolution regardless.
