i-pod interface kit

[Byung-jun Lee]

I HAVE X5 4.4i 2003.NOV.
I AM GOING TO RETRIFIT I-POD INTERFACE.
MY X5 HAS WIDE MONITOR WITH TV TUNER,DSP SOUND BUT NO NAVI.
I BOUGHT A I-POD INTERFACE THAT VERSION IS 2.0.( DIFFERENT FROM VERSION 1.0 :ARTICLE NUMBER 16).
ANYBODY WHO KNOWS WHAT DIFFERENCE BETWEEN VERSION 1.0 AND 2.0?
HOW CAN I SEE ASAP(AFTERSALES ASSISTANCE PORTAL: I HAVE NO I.D AND PASSWARD ON THAT SITE)?
ACCORDING TO THIS SITE ARTICLE NUMBER 16(i-pod installation instruction),I CANNOT RETROFIT THIS INTERFACE.
BUT ACCORDING TO MY OWNER'S MANUAL,I CAN CONTROL THIS INTERFACE ON MY MONITOR.
ANYBODY WHO DID IT?
