Around that time I was a swamper on a moving truck, we had been just using a map book, worked fine. The owner decided TomTom was the future, and wanted us using it, no arguments!
We're going down the highway, fully loaded, probably going a bit faster than we should, and TomTom, in it's infinite wisdom, yells "Sharp left here!" This is Canada, and we were halfway between exits, a sharp left turn would have put us through the concrete barriers and into oncoming traffic. Needless to say, we turned Tom off, and carried on with the map book...
