Ah, it's ok, I have just checked. Some of the other routes plotted by others show up as being circular whereas mind has A-B markers. I thought this was due to a feature that I was missing but obviously not- no problem.
I'm not sure what you mean I'm afraid Andy. The Back To The Start feature plots a path back from the current point to the start. If you have the Auto-Plot feature turned on this will plot the path by road or on foot. I would recommend having a look at some of our tutorial videos if you haven't aleady. The Quick Start video demonstrates plotting a circular route.
On creating a map it uses a A-B method, how do I make this a circular route? I used the "back to start" button which I assumed world serve the purpose but it didn't.
