i stopped at legendary production to be honest <| sep |> GPS ' s have improved a lot over the years . Even if your dad was using a brandnew GPS in 2012 it ' s very possible that it has trapped him in a neverending navigational loop . Without a newer GPS it ' s almost impossible for him to get out of this loop . The best thing you can do to help him is to buy some old GPS ' s it helps if you remember the model he had and follow their navigational routes . Try different search terms other than the address like ' cigarettes ' or ' the store ' and don ' t give up . Don ' t forget to bring a newer GPS to get out of the loop once you find him It took me two weeks to find my grandfather trapped in a roundabout two states over after he had been missing for more than a year . He had misspelled the name of his doctor ' s office and the GPS glitched out and navigated him to that holding roundabout as it endlessly searched in vain for the wrong address .
