The key thing to remember with this installation
is if the CD changer has been installed then the
system had to be programed for it to work.
Once that's done the OS doesn't care what
get's installed provided the device is
meant to be used with the BMW OS.

I found this out when I Installed our iPod
integration kit. We didn't have a CD Player
so the system was not set up to recognize
any device. I saved the installation charge
and installed it myself but it needed to be
recognized.
