I just recently bought a 2012 armada platinum with the navigation. To my understanding if it has the nav system, it does not have the compass built into the mirror. Instead it has a tiny little compass looking thing that you can barely see on the screen and you have to have the navigation screen up in order to see it. My question is can I switch out the rear view mirror that doesn’t have it, to the mirror with the compass built in and will it work correctly? I’m new to the group. Any advice would be appreciated.
