Bezel removal – you can spend 30 seconds by grabbing the bezel from the bottom and pulling or you can spend 5 or more minutes using the trim stick and prying the bezel off. The 30 sec method is as follows. Open the door to the center stack cubby. Reach above door and grap bezel from behind. Pull bezel out from bottom. Work your way around from bottom to the top by pulling the bezel until it pops loose. Work you way around the entire bezel doing this until it is completely free from the dash. Don’t worry, it will not break. It has plastic clips that will come off before the bezel breaks.
Bezel harness – The AC/Htr controls have two wire harness connected to the back. Remove these harness by pushing on the quick disconnect clip and pull the harnesses free. Put the harness in a safe place like the back seat floor.
Radio removal – There are 4 screws securing the radio. Use the 7mm socket or nut driver and remove the four screws. Grab the radio by the metal housing and ease it out. There can be 2 large harnesses, 1 small harness, and two antenna cables on the back of the radio. All harnesses and cables are connected to the radio by quick disconnect connectors. Push the quick disconnect clips and disconnect all harnesses and cables from the radio.
Many use a file or rasp to open up the plastic enough for the replacement radio. May be easier with a dremel but certainly not necessary. I'm partial to the Kenwood line, basically because the NAV is Garmin and you get plenty of features for the money.
Make sure you get all the adapters needed, especially if you have and want to retain the steering wheel radio control.
Being aftermarket, I don't think the dealer needs to reprogram any security features. If you were swapping out the radio for another chrysler radio, the vehicle computer may need to be programmed with the radio serial number.
