Transmitting infodata on MM-CAN

In my first experiments with can bus, I send message to instrument cluster of my kuga mk1, I replace the radio info and the street name in the nav mode, and this is the result.

The text are ascii in hex, I use the windows programmers calc to convert ascii code to hex.

What i found in my research is that MP3 played from USB (FL Mondeo with S&C) gives titles on ID 4C7 (MM-CAN),
Phone via Bluetooth uses 4C3, 4C6
Radiotext and Navigationtargets comes via 4C1 (MSB is multiplex-index)
Also 4B0 (Bluetooth Musik, multiplex)
4B2+4B3 Station names

That could absolutely be true. I did not investigate this further, even if i got all kinds of satnav systems here at hand, but too less time, you know
These are only my findings with an MCA.
It would be good if we could share CAN IDs and meanings on behalf of functionality...
