Eh??? loads of alpine upgrade threads. Never heard of the car needing recodig to recognise the amp! The supply to the amp is tapped off the speaker signal to the fronts after its left the head unit. Power is straight from the battery in the boot. The install is completely outside the intricacies of the bmw computer / coding requirements. Sounds like you're getting ripped off double time!!!
