I am about to remove my Symphony radio and replace it with an Alpine. Did I see something posted that said there is a wire to be cautious of that is tied into the rest of the cars electrical system? (meaning, not your average radio stuff) Thanks for reading, I know there is an Audio forum, but not much action over there. Thanks in advance.

I'm about as vague as your original message, so probably not a big help, but I remember that there is a possibility that some aftermarket radios will connect the OBD signal to 12V. This isn't so much a problem for you, but anybody who tries to do OBD work on your car by connecting to the OBD connector may fry their diagnostic tool.

Look through the Vag Com site for more info.
