Do not buy for Nuvi 7XX,
This review is from: Navitech clip bracket back plate mount for Garmin Nuvi 2**, Nuvi 2**t, nuvi 2**w, nuvi 2**wt series (Electronics)
This was strongly recommended at Best Buy. Actually, they said the old mount was discontinued in place of this.
Unfortunately, the Nuvi pops out. Not as bad as the suction cup mount falling off the window, but still dangerous.
