I'm impressed with the product and fitted very well in the car and right now I'm enjoying it in my car, my friends driving the same car are also impressed and they plan to buy it also.
The seller has very quick response time for questions. There is no installation manual though it is not a problem because the radio install is quick and easy if you have factory radio installed. My unit came with the plug in the wrong can bus decoder, there is 2 canbus decoders, when I swapped them it worked well, be aware that you must take pcb board from A/C control unit and install Into radio.
