This is what I found out so far on those radios... They get there power from a class 2 serial data wire... Basically these radios are coded to the cars PCM... Just to allow that type of radio to work in another car (even that same year and model) the radio would have to programmed that specific car... If I where to open one of those radios up I could just bypass the class 2 serial data input wire location and solder a wire to the board and the radio should work just like any aftermarket radio... Now finding where that location without a schematic could be difficult but possible by reverse tracing the board... Do you know anyone who needs or wants a factory stereo that can work in any type of car?
