To all- this has been going on since 8/25/08 That's when I first posted it on the side imaging site labeled as SLOW GPS, even had it posted as a sticky here on CC for over a year. When you went too slow the boat symbol would get confusednot know where its at and over & under correct, along the way thru a HB update they added the donut-as named by Cane Pole so when you went slow donut would appear. I guess this was to represent confusion???? Do some searchs on SLOW GPS yep same guy different name.......
