My G20 Speedo stopped working. I'm using the GPS on an old cell phone with a speed app.

The cable was replaced several years ago, I went under the body today, disconnected the cable (the little sleeve inside the smaller cable is there and ok) and hand turned and it registered at the head. Wondering if the shorter cable from the trans is bad, any ideas or recommendations appreciated.

Thanks, Doone
