It is very similar to what you have overlapping map. One of maps (was switched in menu) have no detail but it draw priority is the highest!
What maps do you install to Nuvi? Do you have basemap.img in .System folder?

Hi Giomen,
It's actualy gmapbmap.img (This is the pre-loaded Basemap)
I suggest that user removes all non pre-loaded maps and restores only maps that came with the device + hard reset.
