Originally this device was not included. After consulting the support, it turned out that the Can-Bus decoder was defective. They said they were looking for one that actually worked, and then they dreamed of me. I had a previous generation CAN bus decoder that allowed me to modify it. The cable connector was the same but the pins were slightly different. Different pins refer to different functions, so it's probably a difference in supported functions. 2 stars not for head unit but for support.
