Good replacement09/23/2013 ByPhantom Cobra This unit replaces the original if or when it breaks and works just like the original. It does not fix the readings on the speedometer to make it accurate. I don't think anything will. My only complaint is that there is no option to include all the electronics that attach up to the speedometer. But if everything else works, most likely, this is the culprit if your speedometer does not read anymore. Saber delivered in good time and the price is reasonable compared to others I found.
