Pretty simple job. Just Pull out on the two trim peices that are on the outside of the radio. Set them aside. Then lift your center console and take a phillips screwdriver and take out the two screws that hold that part on.
Next, unscrew your shift knob. ( If manual.) ( If its a auto you'll have to figure out how to get the console over the shifter.
With the center console off you will have complete access to the 6 or so bolts that mount the stock head unit to the dash.
Remove those and all you have to do is unhook you wiring harness. I think you have to un hook the a/c wiring harness to the switches to get the head unit out.
thats the trickiest part. one of the a/c switches has a weird connector on the back and its a kinda tight fit. I used a small flat tip scewdriver to get it undone.
Becareful it is delicate. ( I hooked up my Pioneer 9800BT with Bluetooth ect.
make sure you have a chrysler antenna adaptor unless stated differently by your aftermarket radio installation. And of course your wireing harness adaptor.)
Good Luck!
