Would like to fit a double din into my accord with navi, however I don't really want to be forking out for the fascia adapter. Does anyone know if its possible to leave the navi in place with ac controls, and then fit double din in the space below it? Using one of these adapters? Looking at the back of the navi unit there are three connections? So assuming one is for the navi and DVD Another for the stereo side And the other for the air con. I could potentially leave the navi in place, unplug the DVD and stereo from it, leaving it purely for A/C Then fit a new double din beneath it using the stereo ISO connection? Obv the DVD side would be removed Any massive flaws in my plan?
