Hi , There must be a method by which you can set a final destination but also indicate a location that you would like to visit 'en route'. Can some kind soul explain to an idiot how that can be accomplished!

 

Many thanks in hope!!

 

Try picking the intermediate destination first then go back in to select a destination and it will ask if you want to replace the current one or add it to the end.

I think you have to set a "route" rather than a "destination". Instructions in the manual.
