André Gaul documented a mounting kit [1]
It's just a prototype :) but with some foam around the handlebar and careful positioning to avoid bumps, a basic attachment like this might work [2]
Keep it charged
If you want to keep the GPS running and have the screen on or with a long timeout, you'll need a way to supplement power on a long trip.
If you decide to try solar, it's recommended to get a flexible panel and attach it to your backback or something like that. It's unlikely anything below 10 watts will keep things running. (todo: add some data points)
The alternative is to steal energy from the crank. You can do this with a hub dynamo or possibly with an induction generator like the one on the reelight [3] (warning... overuse of flash)
The regulator will have to be a do-it-yourself project regardless of the power source. See [4] for one approach. If you do want to try a switching regulator, there's a nice little pre-built module in the form factor of a linear regulator: [5]
