When in use, it is clipped-on and thus, attached to the ProClip Vehicle Dashboard Mount.
The advantage of this positioning, ProClip says, is that you can see the BlackBerry and the road at the same time.
Basic price is $36.99 for a Padded Holder with Tilt Swivel.
There's also a Padded Holder with Tilt Swivel and Cigarette Lighter Charger for $69.99. But with the cost of cigarettes (not that I wouldl know), I'd bet that ProClip model would lead to far greater expenses over time.
