The NaviGPS isn't ideal if you're away from a source of power, since its internal battery lasts about 1 day, and you can't just put spare batteries into it.
It might be possible to get somewhere with a USB power-pack to recharge it overnight (that's what I used for a 1-week trek, which meant constantly feeding batteries into the usb-recharging-gadget to try and keep the NaviGPS' internal battery charged - not very efficient) _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
