Terrific Product12/07/2013 ByMr.Philadelphia Installed this on an '02 330i. Plug & play unit will work for both pre- and post-2002 cars with full functionality of car controls and Ipod controls -- also charges your ipod. You also have the option of installing a 3.5mm aux. input port using an IS335 kit for universal function with any device. Ipod connection provides higher quality, factory level sound.
This is not the same as an auxiliary wire that works off the cd changer. This deletes the changer and replaces it. So for those who don't have a changer, this will work.
Awesome installation video. Enfig was highly responsive to my questions. The only thing I would add is that if you have a post-2002 car, ground the unit. The ground wire from the 10 mini connector (white plug that fits into the larger black one) can be attached directly to the head unit casing. Strip off an inch or so of insulation, unscrew the black plastic cap on on the back of the unit and secure the ground wire around the stud.
