Carputer / CarPC on X3?

Thanks for the reply. I'll have to chew on those a bit. I have the CID set up on it's own ibus currently to try and see what messages it sends. After sending any broadcast message to wake it up, the CID sends the following messages:


46 03 80 10 D5 CID to Cluster
46 03 D0 5D C8 CID to Navigation
46 03 80 1D D8
46 03 D0 5D C8
46 03 D0 5D C8
46 03 80 1D D8
46 03 D0 5D C8
46 03 D0 5D C8
46 03 80 1D D8
46 03 80 1D D8
46 03 80 1D D8

So the 46 is a device ID beyond just the buttons. As you can see, the last three messages are aimed at the cluster and may be a ping that needs a 'keep alive' response. It's interesting that you say C0 designates the radio buttons - on the e39 with navigation, F0 designates buttons used to control the radio. If you can capture and save a full log with ibus monitor or ibus analyzer, I may be able to determine which packets are the appropriate response. Thanks.
