HTTP: Yeah, that's what I thought to. What I meant was, if he wasn't sure if the speedo was now right or not, a quick drive with a hand held GPS unit would tell him. Myself and alot of my buddies have GPS's as we are fishing nuts and use them all the time. If there was no change, it would save him a dealer trip. The GPS units today are really accurate, mine will tell me how fast I walk. Amazing ain't it?
