If you have a contoured dash that won't allow you to mount your eTrex level the Garmin eTrex C Auto Windshield Suction Cup Mount is for you. Stick the mount to the inside of the windshield or window and snap eTrex into place. The bracket is jointed, so you can adjust it and get the unit out of direct sunlight.
NOTICE TO DRIVERS IN CALIFORNIA AND MINNESOTA: State law prohibits drivers in California and Minnesota from using suction mounts on their windshields while operating motor vehicles. Other Garmin dashboard or friction mounting options should be used.
