You could use the "Brodit" accessory mount that TomTom sell (see
Here) but getting hold of this product in the USA is difficult as they only sell it in Europe for some strange reason.
Another option is available though which involves using the mount that was supplied with the device, but you do have to take your "as supplied" mount to bits:
First off the Brodit/ Pro-Clip with a TomTom "Ball" Attached and the donor mount, in your case simply screw the Brodit "Ball" to your Panavise unit, the Pro-Clip "Ball" can be found by clicking
Here :
Look at the rear of the mount and you will see two Torx head screws (size T6) remove the two screws:
Using your thumb nails seperate the front face from the mount, it doesn't take much force but is a little bit fiddly:
Remove the four T6 Torx screws that are retaining the "ball" cover plate:
The ball cover plate can now be simply pulled off the ball and set to one side:
Remove the three Torx screws that are retaining the rear ball cover.
This component is also retained to the housing by the one slightly larger "Tab" that sits in a slot at the bottom of the mount, Once its free from the actual mount simply pull this off the main ball using a little force, the mount is now fully in bits:
Reassembly is quite staight forwards, position the main housing over the Ball.
Push the rear ball cover over the ball, make sure the larger tab is correctly seated in its slot and secure with three T6 screws:
Puch the ball front cover plate back on and secure with four T6 srews:
Put the main cover back on and secure with the final two screws in the rear of the mount, here it is shown attached to a vent clip:
Finally with the device in the car:
