Maybe you just need to buy a Bluechart chip.

I believe that Garmin's model numbers require a letter after the number to designate a built in chart. 78c has marine charts, 78t would have topo map, etc. If it has no letter, it only has a low-res base map, and you need to buy one of their Bluechart chips to have the built-in chart.

Don't go throwing away your 78 - it might be cheaper to buy the chip.
