I think I posted this in the wrong forum the first time.

I just bought a 2001 A4 quattro. It has the stereo with a CD/Cassette and a changer in the trunk. I really impressed with the quality. I want in dash GPS and an MP3 player that reads SD cards. I saw that Audi offer this as an option and I found some cheep at salvage yards.

My questions are: I'mm guess that any navigation system from 2000 must be really primitive. Is this system any good? Also, will one of these systems just plug into my car or do I need to buy some extra parts? What about the GPS antenna?


Thanks!!!!
