Removal of the original unit is quite simple. Just remove the two phillips screws holding the cup holder in place and pull out the cup holder. Remove the two screws holding the ash tray in place and remove the ash tray. The entire front bezel on the dashboard can now be removed by grasping and pulling forward. It is held in just with clips at this point. Remove the leads from the auxilliary plug and cigar lighter. Using a socket set and a 10 mm socket, remove the two 10 mm bolts holding the head unit in place. Slide the head unit forward, disconnect the two flat wire connectors, the antenae, and the ground connection (requires 10 mm socket as well). The head unit can now be removed. Replacement head units direct from Dodge are VERY expensive as are repaired units which I haven't had very good luck with. Your best option is to try and find a used unit for a good price. Fitting an aftermarket system will be pricy and tricky as the original system utilized an external amplifier located in the panel behind the drivers seat (some models have other amp locations) and a component type speaker system. Good Luck!
