Infotainment/HUD Issues w/ Android Phone

I'm posting in the hopes that someone else -with an Android phone- may have encountered any items like this and may have a fix:

- Phone connects correctly to Android Auto via USB, does not always connect to Bluetooth for phone audio. Infotainment screen will show indication of incoming call, but you can't actually answer the call and talk with the caller.

- No audio from the audio system. Have to force the Infotainment system off (long press the "power" button for more than just mute) and then back on again multiple times to get audio. When it does finally begin working, volume level has been set to 0.

- I have the HUD set to show speedometer plus audio info. Incoming calls will show the phone number here during the call. Upon hanging up, audio info is not restored (phone number remains).

- Forcing power down of the Infotainment system will show "Audio off" in the HUD. Powering the system back on does not update the HUD info and continues to show "Audio off." Cycling through the secondary data items in the HUD will show correct audio info upon returning to that screen.

- Android auto will attempt to do initial setup even though the phone and Infotainment system have a saved entry for "the other" device.

- I have a thumb drive connected with a large number of MP3 files. Selecting USB as the audio source does not always restore the "Shuffle" setting (which I always use). Leaving the USB as the source and turning the car off and back on will also sometimes result in the Shuffle setting getting disabled.

I've added the HUD and USB items predominantly because of the chance that they are interrelated because I do use Android Auto which operates over USB.


I have personally done software updates on the car 3 or 4 times. My phone is exactly the same phone (Google Pixel 3 XL) that I owned when I first bought the car and have kept its software up to date throughout the course of time as well. Aside from the monthly security and feature updates that I install when Google releases them, I have only done one overall Android update from Android 10 to Android 11 in the September 2020 timeframe. Largely, the issues (aside from the Shuffle option) had gone away after a couple of months of owning the car. But, they're all back and with a vengeance and I'm wondering if anyone else has had similar issues and fixed them (especially the ones related to the phone).
