The ball mount fits my garmin nuvi as expected. Mounted on dash to hold garmin. Exposed to constant sunlight and holds firmly.
The ball that the gpd snaps in to is smaller than needed so the gps is loose and falls off or wiggles madly in all directions due to zero gripping ability. Falls off after moments. Then the ball holds the nuvi so loosely it flops all around.
Amazon is really not helping in that being on vacation and in a remote area of the nation, it is very hard for us to get to a drop off point to return the item. Do not buy this item.
Spend the money and get a real garmin mount, and save the headaches. These suction cups tends to lose suction due to cracks in rubber, and navigator falls off glass.
