A:Answer Likely. It goes OVER the existing mirror rather than replacing it. However, it's possible that some cars have mirrors that are mounted via some method that would make it impossible for the straps to go over (car design over the years has included some weird choices). Unless you have one of those cars or trucks, though, then this would be connected by straps that go around your mirror. It looks a little bulky, but it works well.
Otherwise, if your car has a cigarette lighter slot to provide power, it'll work.
