I recently bought a Rexing V1 dashcam as a replacement for a G1W cam. I tried using the G1W's suction cup mount, but the tab-slot mount doesn't fit well into the Rexing's T-slot mounting face. I need a suction cup mount because it will be used between several different vehicles (my work truck and personal car), the adhesive mount isn't a good idea, I would have to buy extra mount plates, and don't want adhesive on the glass. The tractor-trailer vibrates and needs a good snug fit with the Rexing T-slot mounting point. I have looked at a lot of different ball+socket suction cup mounts, having trouble finding one with the rectangular shape which fits this mounting face.
