…if you want to create your own maps, you can do this with the 60CS. With the H20, you can only add tracks. Lots of them, granted, but it is still a significant limitation, especially if you want to add contours.

There is a significant progress in regards of building your own maps for Lowrance iFinder. More details in Yahoo! MapCreate Format Group:
Sure enough, information is posted there on a new tool, MP2LCM. I covered how to obtain data and create MP files in my book, GPS Mapping – Make Your Own Maps, but the ability to transfer those custom maps to current Lowrance units is a new development. Now I haven’t tried this yet, so if you have, chime in and let us hear your thoughts. Congratulations to the MapCreate Format group for all their efforts.
