Comments about Garmin GPSMAP 640 Navigation System:
I expect a marine product to be sturdy. Dropped this thing 2" from the deck and it cracked. I owned a 276c for years and never had to worry about it. Display needs to be brighter. Auto guidance should be built in for this price. Lookout Garmin, smart phone apps are coming for you.
