My daughter's car... We disconnected the battery when replacing the window regulator only to find "SAFE" mode on the radio. The Radio card in the owners manual has a code that did not work. When we pulled the radio from the dash, we found out that it is a different unit than noted in the manual. The serial of the "new" unit stuck on SAFE is VWZ9Z7W2017899 I was considering just getting a cheap aftermarket replacement. However, there was an after market CD changer added at one time, and I have no idea how they wired it. (Duct tape all over the wiring) A working code would be greatly appreciated.
