Hi, I am looking at the wiring diagram for the nav and radio and there are two wires (TXM+ and TXM-) that come out from the cd changer to amp. From amp, there are another two wires (TX+ and TX-) that go to the radio unit and eventually the display. I am nowhere near being a novice in electronix, but could someone enlighten me and say, there may be a hope to have the CD-TEXT support in this car, 2003 gs with nav+ml? What would I have to do to convert the display to be something more literarily useful than a numeric robot?

Here is another link, seems only UK has this md changer display.
