I'm afraid there is no way to recover a route you haven't saved if you have continued to plot more routes since. If you have an unsaved route and have not plotted any more since, the route panner should offer you the opportunity to reload your unsaved route.
Oh, no! I didn't save my updated route because if I did, I would have to rename it...again! I was thinking it would save automatically, but it seems to be gone. Is there any way to get it back??
John, you have been so helpful, and now I didn't save the changed route. Thank you again.
