I have a new jetta and I wuold like to change the original vw radio to a Sony CDX-M8805. I was told this to install it would be a problem with the automatic transmission and the computer, because of the jetta's security system. Is it true?
If somebady knows about this problem please write me down. Thanks: Istvan

the only thing i know of is the security system might shut off power to the main harness until a code is entered into the system. The same thing happened when we had to disconnect my grandpas battery in his mercedes he had to have it serviced by a dealer. Check with your local VW dealer before doing any work. Goodluck
