Wedge Mounts, Cam-Lock Mounts and the Cam-Lock Adapter
Here is a little information to help with mirror mounts. The Wedge, The Cam-Lock and the others.   Gentex mirrors mount on the standard Wedge windshield mount found on most GM, Chrysler and Ford vehicles.   As a general rule, vehicles built in the US use the Wedge style mirror mount. Vehicles built outside the US use either the Cam-Lock style mirror mount or a proprietary, brand specific, mount. Most Japanese built vehicles use the Cam-Lock mount but many recent model Japanese vehicles use the Wedge style mirror mount. Most current model Nissan, Infiniti, Toyota and Mazda vehicles use the Wedge mount. Most vehicles built in Italy, Germany and Korea use a proprietary mount. For vehicles that use the Cam-Lock style mount, a special Cam-Lock adapter is available to allow mounting of a Gentex mirror. Mounting a Gentex mirror in German, Italian and Korean vehicles is usually not recommended because it requires the removal of the proprietary windshield mirror mount. The best way to know what mirror mount your vehicle uses is to compare your mirror mount to the pictures below.
WEDGE MOUNT Wedge mount mirrors are generally standard on vehicles manufactured in the United States, regardless of vehicle make. However, there can be exceptions. Wedge-style mirrors must be removed by loosening a small screw or clip, and pushing the mirror up towards the roof of the vehicle. If your vehicle's mounting system looks similar to the photo to the right, you have a wedge-mount mirror.   Some examples of Wedge Mount mirror bases:
CAM-LOCK MOUNT Cam-Lock mount mirrors are generally standard on vehicles manufactured outside of the United States, including some U.S. brands. Cam-Lock style mirrors must be removed by turning the mirror 90o so that it is perpendicular to the dash, and pulling down on the mirror.

Other Mount Systems and Roof Mounted Mirrors

Some vehicles that fit into this category: Acura, Audi, BMW, Hyundai, Kia, Mercedes Benz, Porsche, Saab, Volvo & VW. Most vehicles built in Italy, Germany and Korea use a proprietary mount that must be removed from the windshield and replaced with a Wedge mount before mounting a Gentex mirror. Mounting a Gentex mirror in German, Italian and Korean vehicles is usually not recommended because it requires removal of the proprietary windshield mirror mount.  If your current mirror is mounted to the roof/ceiling of your vehicle or if it uses one of the proprietary mounts you can request a free Wedge windshield mount button kit with the purchase of a mirror. This free Wedge mount kit includes a wedge mount and glue so you can mount your new Gentex mirror to the windshield of your vehicle. Note: If you need to remove the current mirror mount from your windshield, it is recommended that you have it removed by a windshield professional because the risk of damage to your windshield is very high when removing the existing mirror mount.
