GaryW What would cause the unit to drain my battery if the car sits for several days? The car has a new battery and the charging system has been tested. The only change to the car is the new radio.
Leo GaryW It’s possible that the battery drain is caused by the CANbus connection. You can try disconnecting the CANbus and see if the problem still occurs. If that solves it, we can also replace the CANbus module for you.
Leo Sergio Could you please share your vehicle model and year? This issue may depend on the specific trim level. It would also be helpful to know whether your system uses a CANBUS and which version of the head unit software you’re currently running.
