The in-dash radio uses the speakers that are the same for surround sound system. when ignition key is on it transferres speakers from dvd/surround to radio.
Sans a discussion on safety etc.... I want to play my XM through the surround system while going down the road.
Does anyone know the location, and have advice how to override that relay?
There is a swutch that overides the system to play the radio with the key off but I'm looking for the opposite.
