I sent Garmin an email a couple of days ago but got no response........I might give them a call next week.........My legend still works fine (or at least as good as it ever has), and I don't really need a new unit yet.......That said, I didn't really want to spend the $400 + for a CSx......and the legend is smaller and lighter.......and......25 hour battery life for the H series legend........
If it has the same chipset then I'll probably bite........
