so i have 2 Hds 5 units, one at the helm and one at the bow. The one at the bow is a lake insight unit and when i am moving on the gps it shows the lake map chip contours and the boat triangle but does not leave a trail behind, however the one at the helm does? is this just a feature i have failed to turn on or is there something wrong with the unit?
