Hello, I am having an issue with my NAV VI and I am at a loss and hoping someone can help. So, I start my bike and the NAV boots up and lands on the main screen. I like to view the screen with all of the bike data in all of the individual little boxes. I also like the map screen, but regardless of what screen I switch to the little "back" button in the lower left corner will then promptly highlight itself and switch back to the main screen. I can switch screens as much as I like and it will always switches back. The unit has all of the updates etc. Does anyone have any ideas?
