@Roger-l In the navigating app, from the first screen, choose Route Planning. Select the route that you would like to reverse. With that route open, select the drop down tool kit and choose reverse. Check your route before using it for route points that may now be on the wrong side of a dual lane or one way street. This is all easier to do on a PC or mac or even an iPad as the screens are that much bigger. The reversed route will be on your phone via the cloud if you use the PC to edit a route.
