Welcome Wally.
I actually use mine infrequently, but I can attest that once you play with it a little it is pretty much intuitive to set up destinations,etc. Not being real adept and using it infrequently I'll let someone else comment on its accuracy, etc. Like most things, if you don't use it regularly you lose the edge, i.e., as you get older you don't remember , lol.
