Two questions:-
When your car headunit turns on , do you have to accept the safety warning absolving Honda for the crimes you commit while driving and interacting with the head unit. My 2019 CRV does this and I will never buy a Honda again because of this. If you don't tap, then the radio just goes back to clock mode. Just curious if they still persisting with this
For your duo, are your therefore using the USBC (duo) to USBA (car) and getting the issue ?
Perhaps there could be an issue in standard cable but I believe it is most likely the phone itself. Does it have the latest version of Android auto app ?
FWIW, I recently had a 2022 Kia Rio as a rental and plugged my phone via cable to it, Android auto automatically setup Bluetooth pairing and it all worked pretty nicely. Only one difference :- I couldn't use the on- screen keyboard on the headunit while car was in motion inside Google maps (primary use). It said only voice commands accepted. This doesn't happen when I use the CRV. So that's was interesting how the headunit can control other android functionality.
Oh and the KIA also had that stupid safety warning on their head unit at startup so another manufacturer whose cars I will never buy.
