I have an 898 si and am having trouble when I am navigating to a waypoint and I mark structure on my sonar or side view with the cursor and hit go to it wont stop navigation to the original waypoint and if I hit stop nav it tells me it is part of a route and I cant stop so I try to delete the route and it tells me there are no saved routes.The only way I can stop it is to go to the chart page and hit skip next waypoint. is this normal or do I need to send it in for service? Thanks
