Hi. I just bought a Garmin Nuvi 660 for my 99 Grand Prix. I don't really like it on the windshield and the dash is really curved for the bean bag mount. I noticed it fits quite nicely in the opening for the cubby hole below the ashtray (where I currently keep my sunglasses) and was curious as to if anyone had found a good way to mount a gps there. ProClip USA makes a nice product, but they only have a vent mount for that car and I don't want to go that route.
