Custom Maps

[A Fn NOOB]

Ive got Garmin's Mapsource with US Lakes and Fishing Hot-Spots on my laptop. The lakes have depth data, markers for fishing-holes, boat ramps, hazards, etc. Is there a way I can export these maps into MapThis?

Depends on the format - is there an option to export the map, or are the map files a standard format (google the extension)?

If all else fails, you can always do screen grabs, reassemble and rotate them - then specify the lat/lon to get GPS to work.

you can take a TIFF i belive and just use it as a Map reader
