Hey Meister, Just one more question. I noticed there are 2 different aux input parts available. #82110149389 and #82110149390. They have different connections. My car is 08/2003 . CD changer (in the back and single CD in front) , E53 Standard Business CD, Non-Nav. Which part is for me? Or does it matter? Will I even use the connector it comes with? Thanks again.
