That’s rough! For the BYD app, it’s worth confirming if the car’s software version is up-to-date. Sometimes the app functionality is tied to firmware updates, and the dealership might not have updated it before delivery. On Android Auto, is he using a high-quality USB cable? It’s a common culprit when it doesn’t connect. If wireless Android Auto is an option, he might try that too, it’s worked better for me on some systems. Maybe there's a lock setting that was left on or maybe an update that needs to be reversed.My buddy got his BYD Han last November and picked it up in late April with under 12 miles on the odometer. Since day one, He hasn’t been able to register the BYD app via QR code or use Android Auto. Any suggestion?
