Harmon Kardon's ipod system is nice, but to connect it, you would need one of the following:Originally Posted by Brandon J
1) Plug their system into your head unit's aux input (missing on stock E34's)
2) Plug their system into your head unit's cd changer input through a third party interface (none made for stock E34's)
3) Use their wireless FM transmitter
I'd like something that plugs into the head unit like the cd changer does...
