The power vision can correct the speedo eh? I need to do this my speedo is quite fast and i have the power vision. good info

 

I wish this GPS showed the posted speed limit like many other GPS's. I find that helpful.

 

Would be nice but they need to be updated all the time with speed limit changes. I see a lot of discrepancies with mine but it is pretty cool to have.

 

GPS is more accurate than mechanical measurement witch alot of time is dependent on wheel size especially in cages.
