BUYING GUIDE
Will a Mirror Cam Fit My Car?
Mirror cams attach over your existing rearview mirror with rubber bands or clips. They fit most vehicles, but check that the mirror width matches your existing mirror. Some vehicles with rain sensors or auto-dimming mirrors may have compatibility issues.

Adjusting to a Digital Rearview Mirror
The wider field of view and digital display take a day or two to adjust to. Set the rear camera angle to match your normal mirror view. Most models let you switch between camera feed and normal mirror mode. Practice in a parking lot before highway driving.
