Hi all.

I am trying to get my steering wheel controls working on my Chinese DIN head unit. The unit supports it but I cannot get it working and wonder if I've wired up something wrong.

Please see pictures attached. Head unit is connected via an ISO harness to a connects2 can bus adapter. I've then wired up the ctmultilead.2 to the wires coming from the head unit and plugged that into the Canbus adapter.

Key1 5V is connected to its equivalent going to the Canbus adapter.
Key2 5V is as above
GND is as above

Thanks for reading.
