I have a 2005 V8 4Runner with a JBL head unit with navigation. The screen is dead, but it is outputting audio, so I assume repairing it would be more of a hassle then its worth. I have been looking at other non-navigation JBL toyota heads and was curious if switching between two different JBL style heads was plug and play? I'm trying to keep it cheap but functional. I don't have Aux input, but that would be nice.
