I can't help but notice the picture has a bean-bag mount. I used to use those until I was forced into a panic stop and watched in horror as my GPS flew violently into my windshield. Luckily no damage. Had I been rear-ended at high speed that GPS would have been flying into my face!

These days I only use a RAM suction cup mount that attaches to a window (glass). They work great and are just as easily transfered car-to-car as a bean bag. Even during the largest of bumps or most severe braking (or acceleration <img src="/images/graemlins/blush.gif" alt="" /> ) the GPS is cushioned by the rubber mount.

Check out http://www.ram-mount.com/ . They are available from a bunch of web sites.
