I need help from anyone in the know, especially anyone who has converted their non navi to factory navigation. What I need to know is does the climate control for a navi car plug in and mount right up then work fine, or is there some major wiring and bracket making that must be done. I am also looking for that climate control unit from a navi car and also the big piece that goes around the gauges and the screen. Also if anyone knows the factory part numbers or can help me get these I would really appreciate it! Thank you...
