On the "AutoChart Tutorials & Manuals" thread that CamoHunter just posted....the link to "Autochart: How to Import Data & Create a Map" shows the tutorial that came with autochart. Importing .ht files. I've worked through that tutorial and created the Minnesota lake. But when I open my SD card after creating 6 maps yesterday, I only have 1 .ht map. (000.ht) I should have 6 more. When I try to create a map with the 000.ht file it seems to want to create the map in the area I have the simulator setup at on the helix.
