Itrip (no price off the top of my head)
Belkin FM Transmiter both around 40 dollars.
Sound quality sucks for the most part though. Increasing antenna legth helps though, but requires opening the case
Other wise no other way except for ways mentioned above.
Another choice, the ear buds( I'm not responsible for any tickets give, due to this is illegal, well atleast in Iowa, and probly all other states)
