I just bought a boat that has a magellan nav 6500 gps unit. It seems to be in good working condition, but has no c-map cartridges. I have been trying to find out which type of c-map cartidge will work. Does anybody have one of these, or know where I could find out which cartridge to buy?
My other question is whether or not it is worth buying maps for this unit? When I tried boater's world, they said I should just buy a new gps system. So is this unit outdated? I can think of a lot of other equipment to buy unless I really need a different system. Thanks for any ideas. SS
