Cellular Communication System: Removal & Installation Saturn VUE I

Coupling Replacement - Antenna Inner

1. Disconnect the coaxial cable from the inner coupling of the mobile communication antenna.
2. If you need to remove the antenna coupling, use a small wide-bladed plastic tool to cut the double back tape.
3. Verify that all components are stabilized to 20°C (68°F) minimum.
4. Clean the inside of the window with the alcohol prep pad included in the kit. Clean a minimum area of 60 x 60 mm (2 3/8 x 2 3/8 in) around the target location.
5. Dry the glass thoroughly using a lint-free clean disposable cloth. Moisture on the glass will weaken the adhesive bond.
6. Mask off or protect the glass areas where you will be working.
7. Apply Glass Adhesion Promoter P/N 12378555 (Canadian P/N 88901239) to the window in the area where you will install the antenna coupling. Follow the instructions on the product label.
8. Dry the glass as instructed above.
9. Remove the protective film from the protective backing on the inner antenna coupling. Be careful not to touch the adhesive.
10. Align the inner antenna coupling using the template provided and with the correct orientation. If the outer coupling is still attached to the window, align the inner coupling to the outer coupling. Apply firm, consistent pressure to the center and the perimeter of the coupling for approximately 30 seconds.
11. Keep the vehicle dry. Allow 4 hours at 20°C (60°F) for the adhesive to cure after installation. After 4 hours, connect the interior coaxial cable to the coupling.

Coupling Replacement - Antenna Outer

1. If you need to remove the antenna coupling, use a small wide-bladed plastic tool to cut the double back tape.
2. Verify that all components are stabilized to 20°C (68°F) minimum.
3. Clean the outside of the window with the alcohol prep pad included in the kit. Clean a minimum area of 60 x 60 mm (2 3/8 x 2 3/8 in) around the target location.
4. Dry the glass thoroughly using a lint-free clean disposable cloth. Moisture on the glass will weaken the adhesive bond.
5. Mask off or protect the glass areas where you will be working.
6. Apply Glass Adhesion Promoter P/N 12378555 (Canadian P/N 88901239) to the window in the area where you will install the antenna coupling. Follow the instructions on the product label.
7. Dry the glass as instructed above.
8. Remove the protective film from the protective backing on the outer antenna coupling. Be careful not to touch the adhesive.
9. Align the outer antenna coupling using the template provided and with the correct orientation. If the inner coupling is still attached to the window, align the outer coupling to the inner coupling. Apply firm, consistent pressure to the center and the perimeter of the coupling for approximately 30 seconds.
10. Inspect for bubbles by viewing the exterior coupling from the interior of the vehicle. It may be necessary to continue applying pressure to the coupling in order to remove all of the bubbles.
11. Keep the vehicle dry. Allow 4 hours at 20°C (60°F) for the adhesive to cure after installation.

Removal Procedure

1. Lower the headliner. Refer to «Headliner Replacement»(ref-188777-S38989437462005090200000) in Interior Trim.
2. Disconnect the GPS coax from the antenna.
3. Slide the GPS antenna forward toward the front of the vehicle.
4. Remove the GPS bracket fastener and remove the GPS bracket.

Installation Procedure

1. Slide the GPS bracket into position and install the bracket fastener. Tighten: Tighten the fastener to 10 N.m (89 lb in).
2. Slide the GPS antenna onto the bracket and connect the coax.
3. Install the headliner. Refer to «Headliner Replacement»(ref-188777-S38989437462005090200000) in Interior Trim.

1. Remove the fastener located on the bottom of the OnStar® bracket.
2. Tilt the module inboard to the center of the vehicle and pull down the communication interface module (CIM)
3. Disconnect the electrical connectors, the GPS antenna, and the cellular coax cable.

1. If replacing the VCIM, record the 10-digit STID number, and the 11-digit ESN number from the labels on the new module.
2. Connect the electrical connectors, the GPS antenna, and the cellular coax cable.
3. Tilt the CIM inboard and install the CIM.
4. Install the CIM fastener. Tighten: Tighten the fastener to 10 N.m (89 lb in).
5. Reconfigure the OnStar® system. Refer to «OnStar Reconfiguration»(ref-188766-S00907039372005090200000) .
