I thought it might do it for cds in addition to XM. I was driving a friends 04 Ford minivan and the display in his van showed the cd info. I hoped that my Honda could do what a Ford could. Oh well. :-)
On another note has anyone heard of the new product from Monster Cable called the iCruze? It is supposed to link an iPod to your car stereo so that song info shows on the display and you can use the stock stereo and steering wheel buttons to navigate. Its due out next month.
