I've notice that some Base models have the head unit embedded in the center console, which would require some serious customization to allow for aftermarket head units.
Then there are other Base models that have the traditional style center console where the head unit is not integrated. It can be easily replaced with an aftermarket one.
Does anyone have a clue as to what's going on and what's being offered? Perhaps the traditional style center console is only offered overseas. But then again, I've seen members' rides with it as well.
