Default No incoming messages Nav-bus

Hello, I have built myself a I/K-bus transceiver board using Melexis TH3122.4 chip. I am able to read & write I-bus messages when using the WRY colored wire.
However, if I plug to the Nav-bus wire (pink-black at pin 10 on the S2 connector of the IKE), I do not receive anything. There should be something when pressing the computer button on the stalk or the volume up/down buttons on the steering wheel or am I assuming wrong?
If I send a sequence to display a test message on the IPK display, nothing happens as well.

Has anyone tried and succeeded in doing that?
Any ideas are welcome.
