I have several CustomMap KMZ files that I generated with Global Mapper. BaseCamp appears to only render the coarsest level of detail with these maps, but all levels of detail render on my 62s. (I can see more on the 62s than I can in BaseCamp.)
The KMZ that provided my best example was 2.9 MB, so your site blocked the upload. Here's a smaller one. Also, looking at the upload managment, I'm only allowed a total of 2 MB of attachments. Must I go through my previous uploads and delete them?
