I was using a GPSmap 62s while paddling on a local river. For one stretch, the river runs parallel to a road. While paddling this stretch, the marker showing my position was clearly following the road, not the river. When I returned home and uploaded the track to Basecamp, the track doesn't show what the GPS was displaying as my track. The uploaded track correctly showed my position was always on the river.
Is there any way to prevent this from happening?
I'm using Software version 6.10. The maps loaded were Garmin Topo 24K. I wasn't navigating a route and the orientation was set to "Track Up".
