Lost my Color Merridian overboard and had to replace the GPS. When I recieved the new GPS I called Magellan to get a new unlock code so I could load the charts on my replacement GPS. I was informed I would have to purchase a new bluenav CD since they only issue one unlock code with no exceptions. Well my exception is I will never buy another Magellan product Hardware / Software. As for the replacement Color Merridian it is being returned today. In the future I will purchase Garmin.
