These units are sold with road use in mind. What if I wanted to use
one with nautical charts? Does anyone know if the BSB and roadmap
formats are the same?

I'd like to hear from anyone who might be using this equipment.


So long as the GPS can be set to download in Lat./Lon., it can be used for
nautical navigation.

Dennis.

That's good news - so generally the formats of nautical charts and ones
for highway use are the same?
