CAR NAVIGATION INSTALLATION
WARNING
Do not disconnect the negative battery cable. Extensive reprogramming requirements will otherwise be necessary. Wiring harnesses will be electrically active. It is therefore necessary to exercise extreme caution while executing these installation instructions. Failure to do so could result in severe vehicle damage, personal injury, or death from electrical shock. Keep the ignition and radio powered OFF through the final test.
Notes on MOST optical fibers
^ Optical fibers damage easily-handle optical fibers with care to prevent cuts, nicks, abrasions, and crushing.
^ Optical fiber "ring configurations" must form a closed loop to function (i.e. couple the input of a component with the output of the preceding component).
^ Identify MOST optical fibers by their orange, semi-rigid insulation.
^ Electromagnetic interference (EMI) from bundled vehicle electrical harnesses does not affect optical fibers.
A. Installation preparation
1. Read these installation instructions in their entirety before proceeding.
2. Unpack and compare the installation kit contents against the list in Parts Information-Section J.
3. Place the operating guides and customer accessories in the glove box or appropriate storage or stowage compartment.
4. Remove the paneling on the left side of the trunk interior.
^ Refer to WIS document AR68.30-P-4800TX, Remove/install side paneling in trunk"
^ On models equipped with dynamic seat control:
a. Remove the pneumatic pump for dynamic seat control.
^ Refer to WIS document AR91.25-P-1580TX, Remove/install pneumatic pump for dynamic seat control"
b. Remove the overpressure reservoir for dynamic seat control.

3. Unclip the antenna connectors (A and B, Figure 8) from the holder (C, Figure 8).
NOTICE!
Do not damage the ground cable when removing the antenna connectors from the holder.
4. Remove the antenna connector holder (C, Figure 8) from the body reinforcement panel by snapping the clip on its backside out of its mounting hole.
5. Disconnect the female antenna connector (A, Figure 8) and male antenna connector (B, Figure 8) from one another.
6. Connect the antenna splitter:
a. Connect the female antenna connector-with the red retainer clip-(A, Figure 8) to the antenna splitter input jack (B, Figure 9).
b. Connect the male antenna connector (B, Figure 8) to the antenna splitter output jack-with the red retainer clip (C, Figure 9).
c. Connect the pre-wired antenna lead to the antenna splitter output jack-with the black retainer clip (D, Figure 9).
7. Mount the antenna splitter (A, Figure 9) by snapping the clip on its backside into the hole in the body reinforcement panel previously used to mount the antenna connector holder.
E. Installing the base bracket and bracket for the CAR NAVIGATION processor
1. Remove the nut securing the bottom arm (B, Figure 6) of the bracket for the rear SAM control unit with fuse and relay module.
2. Mount the base bracket to the threaded studs (B and C, Figure 6) and secure it with the previously removed nut (A, Figure 10) from the rear SAM bracket and the kit-included nut (B, Figure 10).
3. Mount the bracket for the CAR NAVIGATION processor by hanging the two hinges (Arrows, Figure 11) onto the supports in the bracket for the rear SAM control unit with fuse and relay module.
Note:
Hold the bracket at an angle to hang the hinges onto the supports in the rear SAM bracket.
F. Installing and connecting the CAR NAVIGATION processor
1. Slide the CAR NAVIGATION processor-back end first-into the lower compartment of the bracket (Figure 12).
Note:
Listen for an audible click to confirm the locks at the front, sides of the CAR NAVIGATION processor lock into the bracket.

2. Set the MOST ring configuration to match Figure 15 via path:
Control Units > Information and communication > Audio, video, navigation and telematics > AGW - Audio gateway> Retrofitting of MOST components > F2: restart of optical ring > Retrofitting of MOST components > F2: Actual configuration of MOST components > Actual configuration of MOST components > F2: if correct > Retrofitting of MOST components > F3: Yes, to write the current actual configuration to MOST master > Retrofitting of MOST components
Note:
The MOST ring configuration in Figure 15 is an example of a configuration including all possible components. Some installations will not include all the components shown in the example. If a component is not present, connect the preceding component to the component following the one not present.
NOTICE!
Failure to have the configuration match Figure 15 will result in erroneous system operation and/or intermittent malfunctioning of some or all components. DO NOT alter the configuration in Figure 15 to match the vehicle configuration.
3. Set the instrument cluster to recognize presence of CAR NAVIGATION via path:
Control Units > Information and communication > IC - Instrument cluster > Control unit adaptations > Version coding > Optional equipment - Select "Navigation" Set "Navigation" to PRESENT, then press F3 > F5: To save changes > F3: To transfer coding to the control unit
4. Check the DTC memory of all installed components and the head unit. Investigate and identify any present DTCs. Once identified, correct the source of the DTCs and clear the DTC memory.
Note:
Powering up the newly installed system prior to version coding will set errors in the MOST ring configuration. Ignore these errors during the initial DTC check. If, after clearing the DTC memory, they return in the next step, a configuration error is present. Locate and correct the error.
5. Confirm no new DTCs are present in the MOST system group.
