There are probably lots of older posts about GPS units, so please excuse my ignorance if this is a rehash of old news, but I've never had one and I'm seriously considering getting a unit to use on my sled/boat year round. We're surrounded by hundreds of miles of wilderness up here and my wife's main worry(?) is that I'll get lost....
Neighbor has one and he plots trails on his compuker after we ride, the amazing widget actually prints trails overtop of local topo maps that he has loaded in his hard drive..!
He has an amazing map of local rides..
What I'd like to hear, if anyone cares to respond, is things like favorite features, problems with particular brand/unit, cold (-30 C ) performance, battery vs. plug-in, mounting accessories, ease of use, PC interface, etc.
