Re: Need facts on installing nav
Starting with the 2012 models, the media center has to be flashed by a dealer to operate. It is a theft-deterrent measure. Be prepared to prove (receipts, etc) that you purchased the new nav unit from a legitimate recycler or source, and that is is not a stolen unit. That is assuming the dealer will do it for you, some will not due to liability concerns and other reasons (ie: they want you to buy a new unit from their parts department and make more profit). Best to talk to your dealer before you purchase the used unit. You will need the serial number of the vehicle it was removed from, and the 4-digit code it was originally programmed with (the only way to get the code is to look it up when installed in the original vehicle, make sure you get the code with the unit).
2011 and units are pretty much plug and play. Make sure you get one from a 2011 GC with the proper faceplate and screw locations. Units from most other Chrysler products are different.
