I am selling both Low Speed units and I know they work in my previous 11 Challenger as well as a brand new 14 Challenger..
730N RER With Nav
430N RBZ No Nav, - Unit is brand new, still has plastic on it. Just got it with the car Friday. This unit is actually really nice, Bluetooth streaming audio with the ability to swap saved phones on the fly is awesome..
Looking for $550 for the RER, and 450 for the RBZ.. Local sale also available in the DFW area..
