I'm not a Hi Tech guy. I've read here on the forum about guys measuring the vehicle speed using GPS. I was wondering how you do that. I change the tire size on my fiero and I know my speedometer of off. I would like to know how fast I am going. My wife has GPS on her phone
Thanks

Run a GPS app on your phone.

Low tech, you can just drive down the road, and use the mile markers and your watch to calculate speed.

So she would have to download an app to her phone and where would you get it?
