I love this GPS friction mount. Just snap your Garmin GPS on it and throw it in the car. It does not slide around on the dash, and my dashboard has a slight downward slope to it so I was afraid it might but it stays right in place. No ruining the dash with a sticky plastic mounting disk. It can be moved to a different car easily. I think it's great!
What's great about it: doesn't slide around, can move from car to car
