FYI - There is a NAV kit available from Advent that add's Nav to either a 8.4 or 4.3 screen on 14 and back cars. No 15 cars since they have a different radio.
It is plug and play, uses the +more key on the 4.3 and the Voice key on the 8.4 (or screen push) to enter the system. Sound comes from the factory front left speaker or you can use a speaker that comes with it and even add's an input for backup camera. No Dealer flash is needed for the camera and it even has an aux input, but the audio in is mono for that AV input.

Maps are iGo Mapping USA/Canada.

I am not selling these, just passing along the info. Sorry in advance but didn't want to steer people wrong thinking I can get it for you.
There are a couple of dealers that will sell these directly but generally they are only sold through companies that install at car dealers.

I can tell you the install is a breeze if you are comfortable with pulling your screen out.

If it is not using Garmin maps, I would forget about it!

One great thing about the stock navigation system is that you can update the maps for free!

It may be cheaper, but you would have to pay for map updates if it doesn't use Garmin maps!

It uses iGo mapping, Navtech and teleatlas data. Your correct technically, we can update our factory nav for "free" but not everyone has factory nav. I was just trying to share some info.
