My analysis: issue is with Google ( Android 14 after upgrade from 13).
I had Oppo Reno 6 5G ( on Android 13) before nothing 2a. With Oppo reno6 5g , Android auto worked perfectly fine with my Suzuki Ciaz India 2017 .
With nothing 2a , connected via USB wire, screen shows after a long lag of about 30 minutes , then somehow selected destination, with this sound comes fine as per navigation, but screen freezed.
Same thing happened with my wife new latest IQOO 7 with 5G ( also with Android 14). Same issue with IQOO phone. Screen freezed.
Google had changed something on USB code / bit rate or so , that is why after Android 14 , Android auto breaks on somewhat old infotainment.
But both nothing 2a and IQOo works fine with Android 14 with my Suzuki Ignis 2021 model without issue.
