Joe, I have a 176 C and am very satisfied. The display is small but the new Garmin charts are great and you can expand the display until you have the detail needed. I use it in my truck as well as my boat. One other plus, I just had $5000 worth of instruments damaged by a nearby lightning strike. The 176 did just fine sitting home in my drawer.The only drawback is reading the display in bright sunlight under a bimini. Out in the sunlight the display is fine and at night it is great with the back lighting, but something about the display makes it hard to read under a bimini when there is no direct light striking the display.
