So I verified I can make a map and load it on my older Nuvi 1490 that the map works on and place it on the Nuvi 65LM and it doesn't work. The map file includes a base layer from Topo US 2008 map and the trails layer with the trails. Both display on the 1490 but on the 65LM just the Topo layer displays. If I unselect the topo layer then the trails layer still does not show. So I believe it is being created correctly or as the GPX2IMG program intended to but it doesn't work on the 65LM. I can send you a copy of the img file if that would help you identify what is wrong or if I need to patch the firmware??

Thank you for your help
