With regards to FM transmitters etc, one rule, you get what you pay for! A colleague bought a cheapo one, and they said the SQ was very poor even if they clipped it on the radio itself. Most of them come with a 3.5mm jack so will fit all MP3 players. The thing with ipods is that you can get one that fits your cigeratte socket so charges the unit whilst it plays which is cool and does not use the internal amplifier of the ipod using the line out instead (Slightly better qwuality)

I use a thing called Drive n Play from Harmon/Kardon. Its designed for use with an ipod, it charges, has a screen and controller and can either plug into your car radio via a line in, or via an FM modulator
