one would think its not going to be easy. firstly, the back panel to the levin controls just has one electrical plug, the other models have more cables. secondly, the "auto" function will not work as it uses temp senors around the car to get the car to the desired temp. these would have to be installed in the other models. Last, the change in the circulation mode (face, face&feet, etc) in the levin are motorised back to the controller unit............yeah no idea how that would interface on other models. Personally, I wouldn't bother, but if you do go ahead, put up a step by step guide :)
