Query: Disaappointed in Garmin

I called Garmin to verify the buoy information for Lake Hartwell in GA/SC was on this database, and was told it was. What a disappointment! After installing the expensive Garmin data card loaded with the pricey little datacard reader, I found there is very little added information over the regular database on my GPSmap396. This is one time Garmin dropped the ball, then badly train personnel lied about it. Don't waste your money on this one.
