Home-brew Garmin Nuvi 660 Vent Mount by carianp (p. 3)
This is a view of the back side of the home-brew Garmin Nuvi 660 Vent-Mount holder in our Impala.
The phillips-head screw in the middle of the backing plate holds the ball to which the Nuvi mount snaps into. A hole counter-drilled into the mounting plate allows the 12V power/ FM cable to feed through it.
The Mounting bar is screwed to the back of the mount. It has a piece of felt glued to it to cushion it where it meets the dash.
The cinch bar can be seen with its two threaded holes; it is see-sawed into the louver opening and is cinched up behind the dash by the two screws.
