i.Trek GBFM Portable and Bendable Friction Dashboard Mount for Garmin Nuvi GPS -Comparable to 010-11280-00
The base of this thing is comprised of three parts, a top rubber cover, an aluminum insert, and a rubber/plastic friction base.  It's easy to tell since the rubber cover was already peeling away from the rest of it when I received it.  The friction base is really not very sticky at all and combined with the lightness of the mount, it sends to shimmy around on the dash while driving, particularly if the road is at all rough or bumpy.    I ordered this unit as I believe the bean-bag type mounts are atrociousl
