SATELLITE RADIO INSTALLATION
We are interested in your comments and/or suggestions regarding these installation instructions.
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.
MOST Notes
^ Optical fibers easily damage-handle fibers with care to prevent cuts, nicks, abrasions, kinks, and crushing.
^ Minimum bend radius for optical fibers is 25 mm.
^ 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 fiber cables by their orange, semi-rigid insulation.
^ Electromagnetic interference (EMI) from bundled vehicle electrical harnesses does not affect fibers.
A. Installation preparation
1. Read these installation instructions in their entirety before proceeding.
2. Unpack and compare the installation kit contents against the Parts Information list-Section H.
3. Remove the trim panel on the trunk lid underside.
^ See WIS document AR68.30-P-8150Q, Remove/install trunk lid paneling"
4. Remove the floor paneling, ski bag, rear wall paneling, and right and left side trim panels in the trunk.
^ See WIS document AR68.30-P-4600QA, Remove paneling in trunk"
5. Remove the panel covering the electronics compartment at the front of the trunk.
^ See WIS document AR68.74-P-1000QA, Remove/install rear mounting wall"
6. In the exposed left side well of the trunk, insert the kit-included, 7.5-amp fuse into position # 16 of the rear SAM fuse and relay module (Figure 1).
B. Installing the SDARS antenna
1. Find the preinstalled, foam-covered antenna leads in the recess for the SDARS antenna (Figure 2).
2. Connect the antenna leads to the SDARS antenna (A, Figure 3).
Note:
Make sure the connectors lock into the plastic connector lock-clips.
3. Mount the SDARS antenna to the trunk lid underside by sliding the bottom clips (B, Figure 3) over the recessed panel lip and securing the top mounting tab with an expanding rivet (C, Figure 3).
C. Identifying and routing the cables
1. Inside the exposed right side well of the trunk, find the two foam-covered SDARS antenna leads wire tied to the wiring harness running to front along the wheel well.
2. Carefully cut the wire ties to release the antenna leads and then fold back the foam sleeves to expose the connectors (Figure 4).
3. Route the SDARS antenna leads to the right side of the electronics compartment at the front of the trunk (Figure 5).
Note:
Route the SDARS antenna leads along the wiring harness running along the right wheel well and secure it to the wiring harness with wire ties (Figure 5).
4. Find the SDARS power supply cable coming from the wiring harness at the front of the electronics compartment, remove the tape securing it to the harness, and pull back the foam sleeve to expose the connector (A, Figure 6).
5. Find the SDARS MOST fiber (B, Figure 6) running along the wiring harness at the front of the electronics compartment and pull back the foam sleeve to expose the connector.
6. Carefully cut the wire tie anchoring the wiring harness to the electronics compartment floor and remove the wire tie anchor by unscrewing it (C, Figure 6).
7. Remove the protective caps from the threaded studs in the electronics compartment floor and vertical body panel (D, Figure 6).
8. Insert the SDARS power supply connector (A, Figures 6 & 7) into the back of the SDARS MOST connector (B, Figures 6 & 7).
9. Secure the wiring harness for the roll bars (A, Figure 8) to the bundled wiring harness (B, Figure 8) running through the body to prevent damage when installing the SDARS control module/bracket assembly.
Note:
Figure 8 shows the wiring harness for the roll bars not yet wire tied to the bundled wiring harness.
D. Installing the SDARS control module
1. Insert the wire tie anchor-from the bracket exterior-into the hole in the front bracket arm (Figure 9).
2. Mount the SDARS control module to the bracket with three M5 hex nuts from behind (Figure 10).
3. Mount the three arms of the SDARS control module/bracket assembly to the threaded studs (two in the floor and one on the vertical body panel in the rear) at the right side of the electronics compartment with the kit included, three plastic 10-mm hex nuts (Figure 11).
NOTICE
Do not pinch any cables between the bracket and body panels during installation.
Pinched cables can result in component malfunction or failure.
4. Connect the SDARS power supply/MOST connector to the SDARS control module (A, Figure 12).
5. Secure the SDARS power supply cable to the front arm of the SDARS control module/bracket assembly with the anchored wire tie (B, Figure 12).
6. Connect the SDARS antenna leads to their like color receptacles on the SDARS control module (C, Figure 12).
E. Configuring the MOST ring
NOTICE
Do not kink optical fibers, route them over sharp edges, or bend them in radii smaller than 25 mm.
Damaged optical fibers can result in component malfunction or failure.
1. In the exposed left side well of the trunk, configure the MOST ring (Figure 13) according to Figure 14.
^ SDARS IN > SOUND OUT or UHI OUT
^ SDARS OUT > CDC IN or HU IN
F. Version coding
1. Connect the Star Diagnosis System to the vehicle and perform the version coding outlined below.
2. Set the MOST ring configuration to match that of Figure 14 by using the path:
Control units > Information and communication > Audio, video, navigation and telematics > AGW - Audio Gateway > Retrofitting of MOST components > F2: Restart of optical ring > Verify configuration of the MOST components, then press F2: Actual configuration of MOST components > F2: Continue> F3: Yes (To write the current actual configuration of the MOST components into the MOST master as the future specified configuration) > F2: Erase fault memory
Note:
The MOST ring configuration in Figure 14 is an example of a configuration including every component. 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
DO NOT alter the configuration in Figure 14 to match the vehicle configuration. Failure to have the configuration match Figure 14 will result in erroneous system operation and/or intermittent malfunctioning of some or all components.
3. Check the DTC memory of all installed components and the head unit. Investigate and identify any present DTC(s). Once identified, correct the source of the DTC(s) 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(s), they return in the next step, a configuration error is present. Locate and correct the error.
4. Confirm no new DTC(s) are present in the MOST system group.
G. Final assembly and function testing
1. Verify proper Satellite Radio operation per the following checklist.
^ Audio is functional (radio and CD changer)
^ Satellite radio display is present on the head unit(1)
^ SIRIUS preview message is heard when Satellite Function" is selected on the head unit(2)
(1)COMAND has a hard key for SAT radio; Audio 20 has a soft key for SAT radio.
(2)The vehicle must be in a geographic area that allows reception.
2. Reinstall the panel covering the electronics compartment at the front of the trunk.
^ See WIS document AR68.74-P-1000QA, Remove/install rear mounting wall"
3. Reinstall the ski bag, rear wall paneling, right and left side trim panels, and floor paneling in the trunk.
^ See WIS document AR68.30-P-4600QA, Remove paneling in trunk"
4. Reinstall the trim panel on trunk lid underside.
^ See WIS document AR68.30-P-8150Q, Remove/install trunk lid paneling"
