Ditto on the Edge 705. I'm amazed at the flexibility. For example you can go into Google Maps and "Send" a placemark directly to your GPS via USB cable. The routing is pretty doggone good and shows you how far away you are from the turn so you don't turn one too early or one too late. It updates that distance just a second or two too late in my opinion but you get the feel for it quick enough.

I've used it for things I never intended to use it for. Once you get a map for it you can view the map on your computer on a much larger screen, make and transfer your waypoints to the GPS easily.

Check my other post about using it to find WW2 sites in Japan. I've been taking US Army maps from the internet from 1945 and can pick out just enough landmarks to transfer a waypoint to my map in Road Trip (software for Mac, can't think of the Windoze equivalent right at this second) and then navigate to that spot. I've got to say every waypoint I've ever transferred has been real close to the actual location, usually within a half a block or so.

Okay that's an extreme use for it but another thing I love is the ability to make a waypoint whenever I want easily. I'm one of those people who see stuff I want to check out later and then promptly forget where that place was. No more. Now I just geotag it and can navigate right back to it.

Concur with the poster above that you don't "need" a map but he has skills I don't possess with his Marine navigation skills although I scuba dive and have to navigate underwater without a map. Same. Same. Still a map is the real deal. To make the map disappear you just push a button and you're looking at a highly customizable screen that'll track anything you can think of. Speed, distance, cadence, average this, average that, elevation, heading, climb, and a million other things.

I just use the data screens when I'm just riding the bike then I dump the GPS into some training software called Ascent and it's really cool. It maps your route, etc.

I'm sure a dozen or more other handheld GPS's do the same thing but I'm in love with the Edge 705.
