Home-brew Garmin Nuvi 660 Vent Mount

By Carianp (poi-factory.com)



Here is my home-brew Garmin Nuvi 660 Vent-Mount holder in our Impala. The Nuvi is in its Trip Details view: Speed, direction, distance travelled, time moving, etc are shown.

It consists of three pieces:

1. a 3/8” x 3/8” x3 1/2” long cinch bar – a piece of aluminum stock that fits between two of the louvres, and which is 1/8” longer than the vent opening is wide. It has two threaded holes in it to pull it tight against the back side of the louvre cowling.

2. a 3/4” x 3/4” x5” long piece of wood mounting bar that has two holes matching the threaded holes in the aluminum chinch bar. It has a felt backing to cushion it as it is cinched up against the front surface of the vent as the two screws are tightened.

3. a 2” wide by3” tall by 3/4” thick backing piece into which the Nuvi windshield mount has been dadoed into and which is screwed to the mounting bar from the back. The ball-to-suction cup portion is not used; only the rectangular ball cup-to- Nuvi portion is needed. A 0.66” diameter wooden ball is screwed onto the dadoed portion of the backing plate; the Nuvi mount snaps onto that to help hold it along with the edges of the dado that is 1/2” deep into the 3/4” thick backing piece.




This is a closer view of my home-brew Garmin Nuvi 660 Vent-Mount holder in our Impala.

The Nuvi is in its Map view: Location (car icon) and Route (purple line) along with the next turn are shown

Easily seen here are the mounting bar with the two cinch screws, and the bottom of the backing plate with the curved dado at the bottom (so the Nuvi can be reasily released by placing a thumb in the dado and grasping the Nuvi, with fingers around the top).




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.
