I have an HDS 7 gen 2 touch and anytime I switch to the Chart page it is showing a wide blue trail behind the boat while I idle around looking for fish or structure. While looking for fish or structure I usually split the screen with side imaging and the chart . When I select a new waypoint ( tree or brush ) it won't show up on the chart with this wide blue trail recording. It's probably a simple fix but I can't figure it out . Thanks
