If a person was thinking about installing an aftermarket radio/cd player in his 2002 beetle, is there a difference in the stock radios, and the monsoon radio harnesses?
I replaced the stock radio in our '05 NBC with an aftermarket Pioneer unit and it was fine (the stock radio had a broken CD player and it was draining the battery). The only issue I'm aware of is related to the k-line (Ross-Tech: VCDS: Afterrmarket Radio Problem). The problem there is quite simply not wiring up the aftermarket harness correctly. You should not need to keep the stock radio in the car.Before you do anything with the stock radio, please be aware that it can go into a mode where you have to enter a code to make it work. And, when you do not have the code, there are other things in the car that will no longer work.
