I have a 2004 Audi A4 with a factory fitted stereo. It is the in dash
6 CD changer and cassette player model.
I have just purchase the Navigation Plus unit of a guy on ebay and
need to know what I need to do to get the unit to work.
What GPS antenna do I need? and do I need to change the wiring?
The guy I bought it off said I may need to put a voltage to the safe
pin, but wasn't sure.
