Seeking advice on replacing my stock radio in my Cadillac STS 2008.
I now have a 2008 Cadillac STS. It has the stock radio and cd player.
I would like to replace it with a full color screen type radio with navigation and Bluetooth.
a. if I go the used option, say, a salvage yard, what years of Cadillac would I be looking at that would be interchangeable.
b. if I go aftermarket, do I need to look out for anything in particular?
