I just bought a factory nav unit, and i need the nav disc. What version do i need? 1p,2p,3p,4p???? What versions are you all using? which is the lastest? I also need the gps antenna, are there any aftermarket ones that plug right in? thanks...

 

I have a brand new 2007, using 4p

Does it matter what date of mfg. on the nav unit? Mine appears not to have sat radio. What do the different versions mean? are they nav unit specific? Has anyone ever made a copy of one and used it?

 

If you don't mind me asking, how much did the factory nav unit run you? Did you get it from a dealer? And how easy was the install?
