DUDU 7 CANbus-box

RedCar

My car is an Opel Zafira B 2006 and my HU is a DUDU 7 with latest OS 3.6 and I cannot connect it to Canbus.
When looking for the appropriate version of my CANbox from the list I only find versions for CAN low or high speed. On the power connector which delivers the CAN signal to the HU the CAN speed is medium speed. Is this why I cannot make the connection? What can I do?

Sorry, first picture should be the box.

Your statement is incorrect. "LOW" and "HIGH" refer only to vehicle configurations, such as the difference between the 2WD and 4WD versions of a Toyota RAV4. They refer to different vehicle configurations, not to the low or high speed of the CAN bus.

Use this method to check if the connection is correct.

Ok. I got CAN working not optimal but I get the backgear signal and some SWC function. I will care about the functions later on.
