I have a two year old Garmin Nuvi. It came with a suction adapter mount to stick it on the inside of the windshield. It stopped staying stuck to the windshield. I acquired a replacement mounting device, which has begun to behave similarly. Now, I have to drive with the Garmin attached to the mount, which is placed on the dash counter under the windshield. I find that the device now slides around and often even slides into my lap or onto the floor. I once saw someone who had a dashmount with weights. Do many people set their Garmins on the dash with weights? Is there any other alternative method of mounting or use that I should consider. I am hoping for some advice on my alternatives so that I can continue to use my device without it sliding all over the place.
Are you sure you're using the suction cup correctly? I own a Garmin Nuvi also and the suction cup isn't a typical one that you push against the glass, you've got to use the lever.
The one thing that I have found that causes suction cups to fail is the cup and/or whatever you are attaching to are not clean. Also check cup for cracks.
I've had a similar problem and resorted to just keeping it in a place where it can't fall down. There doesn't seem to be any fix for it that I can see. Probably just bad design on Garmin's part.
Make sure you clean both surfaces w/ alcohol, then slightly moisten the suction cup with water before applying. In my old truck, a chevy 1500, I had the "bean bag" mount which worked awesome, but I now have a VW Rabbit pickup that doesn't have enough room to fit the bean bag mount, and my Ique between the dash and the windshield, so I got a cheap ($5) suction cup mount on ebay that works great! Also check the edges of the suction cup, sometimes after they come for the factory the edges are rough and don't seal.
