DKD LCD Speedometer with Standard CAN-BUS

• It displays D, N, R, P, S gear, and battery current X5/10.

P.S.: If the working battery doesn’t have CAN-BUS communication, then the CAN-BUS speedometer will always be showing lack of electricity.
So, we suggest to do the speedometer as Line communication version if you can’t get CAN-BUS battery.
