Wanted something stable to attach Tom Tom 720 to that was quick and easy to use, without the messing about sticking the mount to the windscreen, only to have it come unstuck.
This fits the bill excellently. However, the problem with the Tom Tom 720 is that the mount is small and doesn't work when trying to mount in a horizontal position (as opposed to vertical). So before I could use the Nav Mat I needed to get an "Arkon suction mount arm" (available from Morpeth Mobiles). This arm is great, is easier to attach /detach than the standard mount and has much better suction.
The combination of these two bits of kit mean that it is a very stable (no slipping about whatsoever) mount for the Tom Tom and vibration free. When not in use is quickly & easily stored in the glovebox (with mount still attached to mat), leaving no telltale marks on the windscreen. Other Satnavs (that can be mounted horizontally on the dash) would obviously not need the extra Arkon mount.
