ipod attaching

[B@fink]

anyone got a suggestion for ipod attachment? I can't stand the radio transmitter option so in my old car i had a very nice sony ipod unit with full control and that was great. What are my options? I've seen 1 thats effectively replacing my autochanger for ipod, one that involves complicated rewiring, and another that suggests it joins pod to the 'changer wiring but says it will still work? I don't give a monkeys about charging the pod, just want the music.....who uses what, where from and how much? simpler the better, i don't want to rewire the thing!
