I have an Edge 810 with firmware 6.30. Despite the fact that "Map Information" is under "Activity Profile", it seems to act globally. This is contrary to what DC Rainmaker says in his in-depth review, www.dcrainmaker.com/.../garmin-edge-810-in-depth-review.html, "This way I can create a ‘Hiking’ activity profile with a different map layer (such as Topos), and then still have my default road riding one be City Navigator. Nice touch." Did this ever work On the Edge 810?
