During installation, make sure that the 3 pin connector from the vehicle does not have a
brown wire in the middle. The 3 pin connector of the phone pre-wiring is identical looking to
the 3 pin connector of the CD changer pre-wiring! Do not use the 3pin connector that has a
brown wire in the middle, but locate the one that has the brown wire on the side! Incorrect
connection will result in permanent damage to the unit and will not be covered by warranty!
6 Locate both the 3-pin & 6-pin connectors in the trunk area. If the CD Changer is present, disconnect the cables
and set aside. If no CD Changer is present, the cables will be bundled and tucked away in the rear trunk area.
Some vehicles will have the CD Changer wiring in a protective sheath which may make it
more difficult to locate. Cars sold outside the USA may not be pre-wired for trunk install.
7 Connect both 3-pin and 6-pin cables to the BMW specific harness.
