Some info on RTL Trap.
I have not had the RTL TRAP for about 4 days.
Unit has been 100%
Yesterday I loaded another map in memory card and did some changes to folder structure of Memory Card Using the Nuvi USB Cable.
On first boot it gave the RTL Trap, I've booted it a number of times after that and no problem.
I'm beginning to believe that it happens when files change.
