Anyone do any work on 01 Era speedometer?

 

My speedo stopped, switched it out to a digital Trail Tech Voyager. They don't make one specifically one for HD so I got the model for an air cooled Honda XR650L. It uses GPS and wheel speed to give you an accurate road speed. Also has a few other nice features like a simple GPS, (no highway maps) head temp gauge, and altitude. Inexpensive fix that keeps me off the 5-O radar...
