I have a Garmin 176 (grayscale) that has been awesome. I have pounded on it for 10 years with various bikes, snowmobiles, boats and car. Love everything about it except the lack of a color screen. It's almost impossible to tell the diffference between my tracks and roads, for example. I'm thinkin' I could just upgrade to a (used obviously) 276c and it would be plug and play, meaning I could use all my existing cords, cards, software, mounts and everything else. Can any 276c users out there tell me if the screen is bright and contrasty enough to see in bright sunlight? Are you happy with the unit? Is it rugged enough to withstand the rigors of off road riding? Any info you could provide would be greatly appreciated.
