GPS Dash Mount For The TomTom GO 720, 730, 740, 920, 930, 930T, 300, 500, 510, 630, Plus, Receiver GPS Systems
Contrary to the advertisement the holder does not work for the TomTom 920, unless you drive your car with your head directly under the review mirror staring down on the GPS. I would not buy this for any TomTom product as I doubt the suction cap is different on the others.
