I have loved my 06 Touring Z for nearly a year now. I enjoy the stock XM radio, but the limited display is disappointing. I know that XM and Sirius both broadcast title, artist, etc with all songs. How could I send that signal to the stock Navi screen? I know that non stock units can do this and don't want to trade out the equipment, just want to be able to connect the XM reciever data to the screen. I think that I would need a part that would also control the Nav screen by setting up font size, background, etc. and be able to switch back and forth from Nav mode (preferably using the Map button).
I REALLY appreciate any good ideas or vendor contacts!!

 

I don't believe that you can.
