Anyone here use a car GPS in the mountains?

I see you've already purchased, but for future reference - guys who snowmobile in the mountains buy used (cheap) car units all the time and mount them on their sleds. Use them to get far into the backcountry in search of that fresh deep powder without getting lost. There's quite a few add-ons available for trails and such available as well. Snowest forums even has a dedicated forum for GPS, and some pretty knowledgeable people on these exact type of things
