I have not heard about the Trak Marine Maps. Can they be used on the units which ARE compatible with the Bluecharts such as the 78sc or 62st ?

Are there any of thoese TrakMaps on this board for D/L ?

I found their web site and it looks like they cover Canadian Waterways and not USA.

I'd still like to give them a try to see if they work on my Marine HH unit.
