When I open picture viewer, I can see the thumbnail images of the pictures that came with my nuvi 1490t, and after resizing all of my images I copied into the JPEG folder, I could see them as well. But my problem is that I cannot:
1. when i select an image to make it full screen, the image changes to complete black.
2. When I select the scroll bar at the bottom, the whole screen goes black.
3. during slideshow, only the first few images show up, then only black.
4. after the images go black, even after i back out, the thumbnails become blank.
5. If I remove my images that I copied, picture viewer works fine.
why is it that my images dont work with the nuvi, when they are the proper resolution (480x212) and jpg format...
