Anyone have some experience and wisdom to share before I make my GPS purchase? Soon I will be purchasing a GPS to mount to my snowmobile for those day long excursions in the forests of the Michigan UP.

My criteria thus far -

1. An excessive amount of tracking points since where we go there are no roads or civilization of any sort to get a bearing off of and I want to track a days worth of riding (150-200 miles) without downloading.

2. LARGE color screen - life moves by pretty fast at triple digit speeds.

3. Turn-by-turn navigation like the CTS-V's is worthless on a snowmobile, see #1.

My current search has lead me to the GPSMAP 276C (http://www.garmin.com/products/gpsmap276c/) from Garmin.

It would be attached with a RAM handlebar mount (http://www.pbase.com/fredharmon/image/27781540) and fed 12 V power from the sled.

Stealth-v I am going to move this to the lounge....more people will be able to read it and respond....It will be better I promise

most of my gps use is waterborne, as in for navigation offshore. I don't know much about using them on land, but one thing I would say is to make sure you have good map coverage.

in general, the garmins are good units. i had one on a previous boat, but sold that boat and upgraded to a raytheon system for a larger boat.

anyways, it appears to have all the right tools on it.
