I just want to let others know my experience choosing and installing a speedometer in my 2001 Club Car golf cart. After looking around I decided to purchase a Revolution GR258-GPS-01. It has an analog meter (2 5/8" diameter) actuated by GPS data. With the provided adapter ring I was able to use an existing 2" diameter hole in the console that previously housed my battery status meter (I replaced the large analog battery meter with a smaller digital one). I ordered it from Speedhut.com (delivered price was $144.96) and there is a choice of colors for the dial and pointer which are lighted. The GPS antenna is provided and it has a magnetic mount. Also included is a small push switch which provides a readout of the top speed. The installation was fairly simple and easy. I did a test run today and clocked in at 24mph. Needless to say, I am very satisfied and am recommending that anyone looking for a golf cart speedometer consider this unit.
