A navigator for all seasons

The versatile GPSMAP 276Cx is an update of Garmin's classic GPSMAP 276C navigator, but with plenty of new offerings. It boasts a rugged chassis with easy-to-operate buttons and a 5" color display that shows up well under bright sunlight. The included powered mount (with AMPS holes) lets you keep the navigator right where you want it, even on a boat. Thanks to its 8 gigabytes of internal memory, you won't have to worry about running out of room for more maps, and you can expand that capacity with optional microSD™ memory cards.

One of its enhancements includes satellite tracking for both GPS and GLONASS, for better location performance in heavy cover. A barometric altimeter and 3-axis compass help you keep your bearings. And it offers new wireless connectivity features — read more about them below.

It also includes a free 1-year subscription to BirdsEye Satellite Imagery, which gives you a photographic aerial perspective of your surroundings.

Planning to buy this for my father. Purpose is for snowmobile trails. Primarily in northern Wisconsin, Upper Peninsula, and Michigan. Is this a good unit for snowmobile trails? If I buy this unit, will I have to purchase and download other maps for trails in these areas? My hope is that itâ??s plug and play..

I was able to find out that you will be prompted asking if you want to to turn it on when you disconnect the constant power cable. Choose that you want to keep it turned on. HTH! My Bio:
