We haven't reviewed any mirror dash cams because the one we did try actually required the rear light cluster of one of our cars to be removed in order for the wiring of the camera that sits under the licence plate to go through the light. This was a no-go for a few reasons, but because of that, we'd be wary to recommend anything we haven't tested ourselves. Our advice would be to have a look on Amazon and read through some of the customer reviews. The Autovox M6 mirror cam seems to get good results: amzn.to/2mH1fZU
