I went thru the same situation, just look for a RER unit that has HIGH SPEED CAN BUS SETTINGS, try on eBay, they go around 800 -1200, or other option that my DODGE aftermarket guy told me, is to install a Pioneer or Kenwood Radio with Navigation, bluetooth, and DVD, they will do it and will still be under DODGE warranty, the quoted that for 1,800. (Which is a lot)...... finally, I decided to buy a REN radio, paid 250 on eBay,(Mygig, with 20gb, DVD, touchscreen) and buy a external Garmin GPS with Bluetooth (Hands free calling) with FM transmitter (199 dlls on amazon) to communicate with the REN radio...I will upload pics of this.
