Quick Question about Audio Cables (yes, I searched)

[wphend00]

Maybe I didn't search well enough, but all of the topics that the search engine pulled up, indicated nothing but Video OUt cables...

So here is my question.

I have a long commute to work, every day.
I bought a new car, that does not have satellite radio.
In order to get the satellite radio moduel for my car, it will cost about $200.00 or more...

So I would like connect my TP to my car's stereo system via the auxilliary audio input...

I know the moguls included a y-splitter cable for the Headset and power, or for a Mini-din headset...but when ever I used that with my mogul, I would only get mono audio. Is there a mini-usb cable taht would provide Stereo Audio out?
