The RAM-B-166-347U-TOM1 consists of a 3.3" suction cup twist lock base, double socket arm, 2" x 1.7" plate and custom hardware for the TomTom Rider 2/Urban Rider. The suction cup base is designed to have a strong hold on glass and non-porous plastic surfaces, including RAM adhesive disks. The mount is designed with a RAM 1" diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm; this allowing for almost infinite adjustment and perfect viewing angles. The included hardware allows attachment of the TomTom Rider 2/Urban Rider to the mount.
