Let me know if you "find" a good nav disc lol.
other than that i believe there is 1 wire for steering wheel controls. but mine was a 99.
Thanks for the info! My new RB1 is coming with a Nav antenna. Any advice where to put that nav antenna
? As for finding a "good" nav disk, i just spent the $90 on a mopar one to have inside my jeep book inside the car, for if i never need it. Im sure i could get the info off the disk, the one im getting is the 05064033AH disk (September 2009), if you need a copy of the disk i get, send me a PM.
