If your car is on the list of supported cars, openpilot will automatically recognize the model of your car by performing a scan of relevant ECU firmware versions present in your car. The presence of certain ECU firmware versions is an indication of the model year, car brand, car model, and trim.
If your car isn’t recognized as supported, your device will fall back to a dashcam only mode, preserving the stock functionalities and the user will receive a notification on the screen.
