I have a 2012 Mazda 3 hatchback touring basic package with a standard radio. I’ve been wanting to upgrade the stereo and add in the navigation system. I’m not so fond of the standard in dash unit that was an option (the one that came by the info and stereo display) that is up by the windshield. I’m wondering if there was ever an option for a navigation/stereo system that was just below the air vents?
