SUBJECT:
Nakamichi CD Changer - Important Installation/Operation Tips
This Service Information bulletin supersedes S.I. 65 11 99 dated September 1999.
MODEL:
E39, E46, X5 with Nakamichi CD Changer
Situation:
In response to initial field complaints of "Nakamichi CD changers jamming during operation", substantial hardware and software changes were introduced to the Nakamichi units. Subsequently, only the improved changers are available from the BMW Parts Department listed under the new part number: 82 11 0 009 836.
In case your BMW center parts department still has in its inventory the original Nakamichi CD changers (p/n 82 11 0 004 616), those units should be returned using return part index TEC41.
The following important changes in the installation process have to be observed when the new, improved unit is installed:
-- When connecting the CD changer for the first time (after removing transportation screws and plastic locking plate), the unit will power up in the transportation mode.
Nakamichi CD changer in the transportation mode:
-- LED above button 1 illuminates green
-- rest of LED's are red.
Manual Initialization:
-- In order to "manually" remove the transportation mode, press and hold button number 1 for three seconds. This will start the initialization process (green LED on top of button 1 blinks for approximately 20 seconds).
When initialization is completed, all LED's above the buttons are off while the two loading guide indicators (located directly below disc loading slot) turn green.
Important:
During initialization process do not move the unit or try to insert any CDS.
-- Initialization process has to be performed only once. There is no need to repeat the process even if the power/I-Bus connector is removed. In case manual initialization was not performed, automatic initialization will start 10 minutes after power/I-Bus connector was plugged into the unit
-- Do not disconnect the 3-pin power/I-Bus connector from the CD changer while the unit is in operation (CD is playing). If it is necessary to disconnect power supply from the changer, ensure that the unit is in the stop mode by selecting either AM or FM band on the radio.
In order to ensure the proper operation of the Nakamichi 6 CD unit, the guidelines listed below should be followed:
-- Before installing CD changer, please make sure that the glove box door operates properly (closes without excessive use of force). If necessary, the glove box should be adjusted prior to installation (refer to Repair Instruction 51 16 360)
When marking the mounting hole locations, make sure that the appropriate template is placed exactly as specified in the installation instructions.
"The upper edge of the template lines up firmly against the REAR (towards front of vehicle) and RIGHT sides of the glove box, while the front edge closely surrounds the latching mechanism".
Any deviation from the above position will prevent the glove box (with installed CD changer) from closing properly.
When mounting CD changer (1) in the bracket sleeve (2), make sure that the side with two foam strips (3) will face the bottom.
In case of reversed installation it will not be possible to close the glove box.
EXTREMELY IMPORTANT:
If the Nakamichi CD changer installation requires usage of power/I-Bus extension cable-p/n 82 11 0 006 458 (X5 vehicles equipped with factory Navigation and/or DSP amplifier, or E46 vehicles with factory Navigation), ensure that the correct power/I-Bus connector has been identified in the left rear corner of the trunk.
Before making a connection, the black 3-pin CD power/I-Bus connector (X18180) has to be identified by checking its wiring configuration:
-- Pin # 1 - Brown wire (ground)
-- Pin # 2 - Red wire (power)
-- Pin # 3 - White (or white with yellow/red tracer) wire.
The X18180 connector is located:
X5 CD and telephone harness location:
-- X5 vehicles: behind the navigation computer support bracket, attached to the audio/amplifier harness (see illustration S65 00 U01)
-- E46 vehicles: at the bottom of the navigation support bracket, attached to the CD 6-pin data cable.
Do not attempt to connect power/I-Bus extension cable of the CD changer to the black 3-pin phone compensator connector (X1765), which has identical connect housing as a CD power/I-Bus connector X18180, and is also located in the left rear trunk corner (see illustration S65 00 U01).
The compensator connector (X1765) is always attached to the phone data/pow wiring harness (on X5 vehicles near 26-pin "D" sub connector, on E46 vehicles near 26-pin ELO connector).
Connecting CD changer with power/I-Bus extension cable to the phone compensator connector (X1765), will cause the CD unit 3 Amp fuse to blow Also, in some cases the fuse for the phone system can fail as well (on X5 vehicles: F74 located in the right rear trunk corner, on E46 vehicles: F39 located in the glove box).
-- After installing CD changer make sure that the glove box closes easily, without requiring excessive force.
Use of excessive force when closing the glove box door can damage the transporting mechanism of the CD changer.
In some cases, due to tolerance variations of glove box assemblies, it is necessary to adjust the glove box door to ensure proper clearance between CD changer and fuse box carrier.
Adjustment example:
In order to adjust the glove box door on E46 vehicles, loosen 4 screws located underneath glove box (1), and then move door assembly (3) towards rear of vehicle (about 2 mm) until easy closing is achieved.
-- Before inserting a CD into the loading slot, please make sure that the loading guide indicator lights turned green (2 loading guide indicators are located on both sides, just below the loading slot opening).
-- When loading a CD, gently insert the disc into the loading slot and do not apply any additional force after loading mechanism starts to pull the disc into) the changer.
-- Always keep the disc level (perpendicular to the face panel) when inserting it into the loading slot.
