Adding Nav to 03 E55?
Im looking for info and advice on adding Nav and Xm to an 03 E55 that didnt come with this from the factory.Is it best to use the factory stuff for this application or can I use an aftermarket deal such as the Eclipse stuff.I have Eclipse Nav head units in other cars that I own so thats why I used them for a referrence.I would like to have the factory stuff installed but would rather have my stereo guy do the work,can the units and all of the needed components be bought from the dealer or some supplier for a somewhat decent price?I havent asked my stereo guy yet so thats why Im asking here.
Thanks for any help,
John
