I too would like to be able to have a direct audio input in my audio stack (NAVI/6CD changer) - a 2.5mm female jack mounted some place discrete (even in the center arm rest ??

, or flying lead
I have the Dell jukebox rather than I-pod, and don't particularly want to be able to control it from the Radio/CD controls, I just want good quality audio out of speakers, without having to pick/change FM channels and deal all those extra bits of cable floating around.
Let us know if you find a good solution.
