That was the Holy Grail indeed, but unfortunately preliminary decoding of the protocol seems to show that the CD changer sends informations to the head unit in the form of numbers (track #, cd #, time) and not in alphanumeric form. It's a pity because the display is alphanumeric (to show RDS information for example)... (*)

Well, you can help in numerous ways, but if you haven't the head unit anymore, one of the hottest topic is to understand the protocol, so you can download the latest dumps from post #51 above and try to find a reliable way of decoding frames.

(*)Maybe after we finish this project, we can try to hack the yellow connector between head unit and stalk + display :-)
