Only for use in the BMW dealer organisation.
The CD changer may only be installed by a specialist workshop that has the required special
tools and manuals (servicing, repair, diagnostics, etc.).
On cars without a CD changer holder in the boot the boot trim on the left must be ordered
separately using the Electronic Parts Catalogue (EPC).

Before installing the power supply cable and the CD changer connection cable, check
whether the required black 3-pin socket casing for the power supply and the black 6-pin
socket casing for the CD changer connection cable are tied back on the left-hand side of
the boot. 
In cars with an on-board monitor radio the CD changer connection cable is only installed
in the boot.

In cars with an on-board monitor radio from production date 9/01 onwards, the CD
changer D adapter cable must additionally be ordered separately using the Electronic
Parts Catalogue (EPC).

Ensure that the cables/lines are not kinked or damaged as you install them in the car.
Additional cables/leads that you install must be secured with cable ties.
If the specified PIN chambers are occupied, bridges, double crimps or twin-lead terminals must
be used.
