2007 Tahoe Factory Radio Output Question?

[PaulR]

Wife has a 2007 Tahoe with the factory DVD radio (flip down screen in back, DVD is loaded into the head unit). I'm thinking about replacing it with an aftermarket DVD navigation radio but am wondering about the outputs to the rear flip down DVD player. What kind of output is there from the radio? RCA or something else?

 

If it is a proprietary connection, is it possible to get and adapter to convert it to RCA to plug into the back of the new head unit?

 

Follow-up. If I do have to replace the factory DVD player, is swapping out the DVD player (and wiring) too complicated or is it fairly straightforward?
