On Route Planner there’s a small blue arrow in a dark grey circle which is placed at some random point a few miles from my home marker. An identical icon is at the right hand side of the screen just below the zoom “+” and “-“ buttons. When this is clicked the screen centers on the blue arrow on the map whereupon the one at the right hand side (the one just clicked) disappears, only to reappear if the map is moved off center. I can’t move the arrow or get rid of it and it appears to serve no useful purpose. It has changed position under its own volition from some other seemingly random point over the past few weeks. Any suggestions gratefully received, thank you.
