Which contry ?
US I think you guys use XM and there is another system I think called Radioinfo ( correct me if I'm wrong any one ) which is a sligtly diffrent version of TMC which is an FM signal which holds a data stream.
XM I think uses the new digital format of TPEG which is in use in the EU but not really transmitted by any one.
Does that help ???
