First Post & First Question [ipod?]

Hello!

i searched the audio tech and the A4 forums for "iPod" but only found one post.

so i offer this:
what are my options to hard-wire a connection for an iPod in a 2000 A4?

ideal solution is to have one cable/plug that charges the iPod battery and lets music flow from iPod to the head unit [factory Bose]. i understand that the connection on the bottom of the iPod can do this, but how do i hook that up to the head unit?

i don't want to lose the ability to use the CD changer.
an FM transmitter won't work due to interference.
plugging into the cig lighter for power is undesirable.

Thanks!!!
