Help want to get an Ipod connection

Hi all

Been trawling the web today and found lots of different connection leads and stuff. But have no idea whats best.

Can anyone reccomend a lead... I think i want the one that uses the CD changer plug on the radio but not sure .

Allways had great advice on hear so thanks in advance

Nearly forgot its a L322 2002 with Tv and sat nav in the front screen (BMW i think )

I went the Mk4 sat nav + Intravee II route and haven't been disappointed. I think there may be a battery charging issue with the latest iPhones though. My iTouch works fine - steering wheel buttons work + track & artist displayed on screen.

Help help don't. Think I can afford the mm 4 mate anyone else just done the lead citing route ??
