Does anyone know the name of the type of speedometer gauge that you can reset with a button? All i know about them is you push a button, drive a mile, push a button, & it's recalibrated...

Thanks.

 

What are you trying to do? If you're looking to verify the accuracy of your cars speedo, try grabbing one of those handheld GPS (Global Positioning System) units & check it while driving. Provided it's getting a strong signal lock, it'll be accurate to 0.1 mph

 

I'm wanting to replace all my gauges in my dash eventually. Just figured I would start looking into it now & I hear that the cable driven speedo's aren't accurate above 100mph
