I know there are few ways of connecting iPod unit to car stereo: PAC units, iDrive from H&K, and some new way of hardwiring ipod to stock system to show all info on head display.

But are there any other ways of doing it? RIght now i'm running via Tape deck...and i hear FM transmitting is not the best way to listen. Car in question is 04 Coupe

 

Your choices are the tape deck, fm transmitter or hardwired. Obviously hardwired is best.

I think I saw on ebay a new system where you attach a tin can to your stereo and then run a piece of string from that tin can to another tin can with your ipod in it.
