The single suction windshield mount is ideal for use with a Bluetooth GPS receiver. Many new cars, particularly some of the French cars and other European models have a new feature on the windshield that is known as the thermal windshield film. These type of windshields can be problematic for Bluetooth GPS receiver users as they block out the reception from the satellites. By using the single suction windshield BT GPS receiver mount, you can place your receiver in the one area of the car that is not blocked by the thermal film, up by the rear view window. For all other cars, the single suction BT GPS mount allows you to place your receiver in a sensible location in the vehicle (the windshield) for maximum results. This solution features a unique one-touch locking lever to insure that the mount stays on the windshield. Also works great as a radar detector mount.
