Yikes! Thats a long laundry list. But I think we can take care of most of it save for the music and the tent parts.
Garmin Edge 705 GPS
Edge 705 GPS
Youre best bet probably is going to be the Garmin Edge 705 (about $540; garmin.com). Its a bicycle-oriented GPS/mapping unit that has quite a long list of features. It will track your location, of course, and handle GPS chores such as marking waypoints. But it also tracks speed (and average speed over a course), distance, time, altitude, ascent and descent, and more. Plus it watches heart rate and calculates calories burned.
It also maps. The 705 comes with a decent baseline U.S. map (roads and landmarks), plus you can add a wide range of other maps, such as national parks topos, through the units microSD slot. And the color screen gives you a good image.
The 705 is designed for bicycling, but works fine as a hiking unit. Alas, it wont play music.
If the price is a bit much, Garmins 305 tracks location, measures speed, time, and other parameters, handles altitude, and tracks heart rate and calories burned. It doesnt have the mapping capabilities of the 705. But when in the world have you been truly lost?"
