I picked up a Garmin Montana and a Ram handlebar mount quite recently. It doesn't position itself as low as I thought it would but it offers really great visibility when it's mounted in position near the left wing mirror. I think the shorter riser might have been a tidier arrangement, but I'm really pleased with it all the same. It's not wired in yet... That's another project I need to get to before the spring.
The iPod Touch fits tidily into a bum bag above the headlight. Vicki was kind enough to let me burn a hole through her bum bag with a soldering iron so the camera lens can see through! :) It wraps around the steering column tightly and points that sucker straight ahead. It's perfect... even better than Paul's "Nancy Boy Man Purse."
