i currently use a radio adapter for my ipod. it plugs into the cig lighter, and you select the radio station to transmit on. It can be moody, depending on the weather and, to some extent, where you are in the city. usually i have it on one station that i know works, but occasionally i have to change stations. It’s a Belkin. I got it at Target for like $15. Works alright. doesn’t take power off the ipod either; cig lighter or a AA battery (which i don’t recommend – it dies quickly and is much less powerful when transmitting). really, a radio transmitter is the only way to go, barring a new tape deck to use a tape adapter or installing an AUX jack to use the thing directly. both would be costly.
