Hey all, I got a quote for an AP800 aftermarket cruise control kit from a Toyota dealership. It was $920 including fitting. This seems expensive, is it? And, also, the controller (the thing with the buttons on it that goes on the steering wheel) sends its signals to the rest of the system via an infrared link to a module situated on the part of the steering wheel that doesn't move. (Near the lever that adjusts tilt and reach). Would this be reliable? And, in fact, how reliable is a system like this?
