Hi everybody. I got my go 620 up and running, put in the destination and started off. After a few minutes, the device switched over to a clip about all the wonderful features of the device. When I touched the screen, it went back the navigation screen. A few minutes latter, it switched to the clip....yada yada. This happened 4 times until I turned it off. I find this somewhat distracting and potentially dangerous. This shouldn't be happening right? How to disable???
