Hello everyone, I just purchased a 2004 tahoe and I want to replace the headunit with an aftermarket one. Does anyone know how I would hook up the stock dvd player to play through the new headunit like it does now? It has the bose system and onstar I know i need the onstar adapter but cannot find anything on the stock dvd player/ Thanks for any help

Pretty sure that the stock DVD player won't interface with an aftermarket unit... I would look into getting an aftermarket deck with a DVD built in
