    As I can see from your post, you have bought a "nuvi 3790T"

    I also have a 3790T, but I have the problem that when I want to load routes with mapsource it happens that: -some are loaded well, -Others are not loaded (although they are in the GPX folder), -Others are loaded but with missing waypoints. I consult, is it a memory problem? why is this happening with the routes? Some routes are loaded directly into the device and they delete themselves.
    I appreciate any information to solve this problem.
