xpeterpx Posted September 23, 2009 Report Share Posted September 23, 2009 I'm planning to change my old oem setup with a unit from another Mk4 but it doesn't have a code... I have the code for my current one. Question: is the radio code coded to the car ecu or the actual unit i.e will I be able to use my existing code for the replacement VW unit?
