You could also try one of those video monitors instead of the mirror. We have one but I haven't installed it yet because the vehicle it's going in is hibernating. One car has the mirror. The other will get the video monitor. If you have/use the rearview camera then the mirror is of no use and the monitor is the better option. The one we have just has a grip base, but my sister bought a windshield mount to hold the screen in her car. With the Blackings, you probably want the windshield mount. The wiring will be a bit ugly, but it's only short term.
