Hi, I've got a 2015 Seat Toledo which is equipped with a Multifunction steering wheel.
The previous owner had installed a Kenwood DNX521DAB with the CAW-KIMUN1 CAN-Bus interface.
My problem is, that the volume button (roller) doesn't respond. (While other functions are working well) The support from Kenwood simply said, that the interface isn't compatible with this car.
Does somebody know which protocol is used between the HU and this interface, which connects with a 13 pin DIN connector?
The other option would be the yellow/green Rem. Con. wire for that I also don't know the protocol.
On the other side I want to grab the CAN messages from the Steering wheel with a MCP2515.
Hopefully somebody can help me with my problem.
