I have a Rino 120 battery powered radio/gps. A great little system. Power cord adapter for car use, battery powered in the backwoods. Radio is a little underpowered but sufficient for my use (usually boat to boat in Northern Canada).

Garmin just introduced 2 new Rino models, with better radio range, but they are rechargeables. In my opinion, it kind nixes there usefulness for backwoods/survival purposes
