I had the same issue with my Nav VI a couple of weeks ago. Riding in to work, the symptoms appears like a stuck wheel. I was listening to music from Nav VI app, kept scrolling as if I am toggling with the wheel. To resolve the first time, I shutdown bike and Nav. Worked fine for a few minutes, I thought that I might have been too rough with wheel. Same ride to work, after shutdown, it happened again. Same symptoms. this time I left it alone, knowing I would be passing by local dealer and I will show mechanic. Showed him the scrolling screen, he shutdown my bike, and noticed that the Nav VI for some reason still shows battery charging. He removed Nav VI and snapped back on. I have not had the symptoms since then. 2 weeks has not returned. Good to know I can refer to this thread and the other thread from Adventure Rider if it returns, I can get my Nav VI replaced.
