Let us know how it works.

What I've found most frustrating about turn-by-turn navigation for bikes is that it's designed to only be useful getting from point A to point B, versus point A -- circular route -- back to point A. It seems like something that would be so simple for app developers to incorporate, but they don't. And I don't feel like spending $400 to get this feature when I've already got an Edge 500 and a $600 iPhone.
