My engineer said the GPS speedo is ok. If anything , it's more accurate.
I had to file the threads, it jammed up real bad. I was thinking of drilling 2 holes in the back and using like a angle grinder spanner to hold it. I ended up using a chain vise grips. Wiring was really easy. I got the dimmer with mine. Also it has shift lights, and an external large shift light.
