Funny story time. My first trip to Europe, GPSs were somewhat of a new thing. I rented a car to drive from Paris to Nice with a stop in Epinal to see a US cemetery where my great grandfather was buried. The car was supposed to have a GPS, but did not. Luckily I had printed out directions/maps - or so I thought.
Once we got out of Paris and on the highway things were good, but then we had to get onto side roads in the French countryside. The directions actually had things like 'after your 21st roundabout take the 3rd exit'. Of course we got lost. I noticed a store that looked like a French version of Walmart and pulled over to hopefully buy a GPS.
Since we were a long ways from any big city, no one spoke very good english and my french was terrible. After pointing and making gestures for almost an hour I finally was able to buy a GPS and go on our way. We did make it to the cemetery right before they closed, and made it to Nice much later in the night.
It makes for an entertaining story now, but if we had not stopped and bought that GPS we would not have found the cemetery that ended up being the highlight of the trip.
