I've orderd OD-LM-01 for use with a dudu7. Steer controlers work because its not using canbus but dedicated wires (thanks Duduauto support for that hint).
The box is in the Canbus list, so I assume that if you wire it up correctly (which will be the challenge) and connect it to port C of the Dudu 7 (or an equivalent port on other Dudu units), it should be recognized.

So my next step is looking into the wires, should not be more that canbus H/L and power (famous last words).
