Not with any success. When driving semi last year I used my dezlcam 785 with one of the Garmin bean-bag dash mounts, but the unit is really too heavy for mounts like that. Even with the stability and smooth ride of an air-ride cab, it would still wander all over the dash as I drove down the road. Eventually I just stuck the thing on the windshield and learned to use it with voice control. I looked into other mounts, but none really seemed any better.
