The market is definitely not flooded with gps equipped motorcycle dashboards. I know it's limitations, which is why I'm hoping there's an upgraded version in the works.
It's gps capabilities remind me of the Garmin I had 12 years ago. Even the Rino's from 6 years ago had the ability to add street maps and do some basic route generation and turn-by-turn guidance. I usually have to put on 40-140 miles before I hit the hit the dirt.
The Voyager might be the best at what it does, being the only one that does it, but that doesn't mean there isn't a ton of room to improve.
