Last night I loaded Gamin 100k topos on my gps and it worked great. Then I loaded 24k state MN topos from this sight. When I looked at my gps to enable one of the two maps, the 100k was not there. So I reversed it and then the 24k state maps were not there. So what am I doing wrong. Thanks.
OK, how do I do that. I was using Basecamp software that came with my bundle on the 100K disk.
