Cool thing at the lake.Brought the C330 in the RV with boat.Got close to the lake.GPS was showing the waterways.Brought the GPS on the boat.showed the speed,which now I know my speed meter is right on the money with the GPS.basicaly shows everything in the boat same as in a car,but the GPS does not know you are in a boat.Shows the arrow of direction I was going.Funny,if there is a road along side of the lake GPS starts recalulating and sounding off directions.
My voice in the GPS I called Darlin,my friend calls her "Women".I don't depend on the GPS on the lake since the software not made for the Lake,I all ready know the lake like the back of my hand for 30 years.Great tool the GPS is anyway.
