Begin antenna navigation replacement by taking out the panel from the rear shelf. A small wide blade plastic piece removes the adhesive to extract the GPS antenna from the rear shelf after which operators disconnect the GPS antenna wire. A razor blade combined with a pad of isopropyl alcohol and a clean lint-free fabric is required to remove adhesive residue from the rear shelf. An isopropyl alcohol pad followed by a clean lint-free cloth should be used to clean the rear shelf where the GPS antenna will mount. Before applying the GPS antenna adhesive section you must remove its protective covering yet you need to avoid any contact with the adhesive itself. Use your fingertips to press the GPS antenna onto its mounting position on the rear shelf for 30 seconds before it achieves complete seating. Secure the GPS antenna cable connector and replace the rear shelf trim panels to their positions.

Before replacing the navigation antenna start with the removal of the rear shelf trim panel. Remove the GPS antenna from the rear shelf by using a small wide-bladed plastic tool to detach adhesive while you should separate the GPS antenna cable connector. A razor blade should be used to clean the rear shelf before using an isopropyl alcohol pad with a clean lint-free cloth. The next step includes using an isopropyl alcohol pad along with a clean lint-free cloth to clean the rear shelf mounting area for GPS antenna installation. Tear the protective material from the adhesive surface of the GPS antenna but avoid touching the adhesive itself. Both installation steps require you to first mount the GPS antenna onto the rear shelf surface and wait 30 seconds until it sets. Then proceed with cable connector attachment and reinstallation of the rear shelf trim panel.

The first step for navigation antenna replacement requires removal of the rear shelf trim panel. A thin wide plastic tool can break the adhesive to let you remove the GPS antenna from behind the shelf before disconnecting the antenna cable. A razor blade combined with an isopropyl alcohol pad and a clean lint-free cloth should be used to clean away all adhesive residue from the rear shelf. Use a smooth border of isopropyl alcohol pad to wipe the rear shelf GPS antenna placement area while avoiding contact with the adhesive backs. To install the GPS antenna place the protective backing off the adhesive and mount its adhesive side onto the rear shelf keeping pressure on it for at least 30 seconds until it fully sticks. Plug in the GPS antenna cable connector before completing the process by replacing the rear shelf trim panel.

In order to remove the fixed Antenna mast, unscrew Antenna mast using a tool with tape on it's surface to avoid paint damages. Then, detach the Antenna mast from the base of the Antenna. For installation, mount the Antenna mast onto the Antenna Base using screws and tighten them to the value of 5 n.m (44 lb in) according to the fastener notice in service precautions.

Start by turning on the Ignition Switch to the on position and enabling the radio reception. Remember the direction of the serrated plastic cable markings to avoid wrong mounting. First remove the Antenna mast then also remove the contact spring before using contact cleaner to clean the contact spring. After extending the plastic cable 30 cm (12 in) you should stop when resistance is felt. Turn the radio off then check that the plastic cable properly retraces itself into the housing while hooking onto the drum housing's gear mechanism. When the plastic cable fails to retract you must turn the cable while continuing the motor operation. Put the contact spring onto the Antenna mast but make sure its flanged end points up. End the inspection of Antenna operation through multiple radio on and off cycles which will enable full mast extension and retraction.

The fixed antenna engineers had thought was to be able to survive most car washes without suffering a scratch and it is impossible to turn it up or down. If the mast is bent a little, it can be straightened by hand or even by the pulling of hand but when it is bent much, the antenna is replaced. The first step is to take out the antenna-mast from the base then take off the lead-in from the antenna, detach the and the bracket from the bezel and take off the screws holding the bracket to the bezel. Then remove the bezel. For installation, begin by mouting the bezel on the quarter panel, then attach the lead-in to the bracket and then mount the bracket to the bezel. Make sure that the bracket retaining screws are tightened to 2 N.m (18 lb in) and the final step would be mounting the antenna mast on the base.

Starting with counterclockwise rotation will enable the fixed antenna mast's removal. Before installation insert the antenna mast into position then use clockwise motion to tighten it down. Tighten the mast to 10 N.m (89 lb in) strength according to the Fastener Notice in Service Precautions.

To remove the fixed antenna mast, you will first need to turn the antenna mast in a counterclockwise direction. Installation: Follow the Fastener Notice in Service Precautions. Mount the antenna mast by hand; turn it clockwise to fasten until it is tightened by 10 N.m (89 lb in).

A service or repair of the Antenna mast requires initial tool surface tape application to protect the Antenna mast paint from damage. Start the procedure by taking the Antenna mast out from its base. Locate the Antenna Base by pulling back the carpet in the rear compartment of your vehicle which should be accessible through the open rear trunk lid. Start by unbolting the Antenna Base mounting and disconnecting the Antenna lead from the Antenna Base. You can remove the Antenna Base from the Antenna mounting spacer by pulling it downwards. To finish installation work connect the Antenna lead to the Antenna Base then push the Antenna Base up onto the Antenna mounting spacer. Fasten the Antenna mounting bolts into the Antenna Base with a torque of 6 n.m (53 lb in). The last step includes replacing the rear compartment carpet before closing the rear trunk lid and securing the Antenna mast to the Antenna Base.

Replace fixed Antenna mast first you need to use tape on the surface of the tool so that it does not harm the paint of the Antenna mast this will enable you to perform the fixing easily then, unscrew the Antenna mast and remove it from the Antenna Base. For the installation, fix the Antenna mast onto the Antenna Base, engaging it and screwing firmly (to 5 N.m (44 lb in) as per the fastener notice in service precautions).

The process to remove this Navigation Antenna starts with unscrewing the left front sunshade followed by disassembling the left front windshield garnish along with the instrument panel IP trim pad. First disconnect the GPS antenna coaxial cable from the Onstar harness by untaping it then unroute the harness from the IP before separating the cable from the vehicle interface unit (VIU). When removing the antenna from windshield and roof panel users must use a razor blade with isopropyl alcohol to clean any remaining residue on the windshield. Draw a pencil mark on the windshield's surface where it meets the black-out zone at 2 mm height (0.079 inches) below and 30 mm (1.18 inches) distance to the side black-out area. Hold up the inside glass with a clean lint-free cloth and an isopropyl alcohol pad while you take away the backing paper from the antenna housing. Begin removing the sticky backing from the metallic strip. Mount the GPS antenna to the marked windshield position then lower the headliner gently so the GPS antenna and grounding tab bond securely before putting the GP antenna onto the roof after removing its metallic back strip protection. The GPS antenna coaxial cable requires connection at the VIU which must travel through the IP and up the left front A-pillar before being attached to the OnStar(R) harness. Place back the IP trim pad and the left front windshield garnish molding before installing the left front sunshade.

A tool with surface-tape will help unscrew the Antenna mast while maintaining the paint's integrity. The next procedure requires removal of the Antenna mast from its base board. Guide the Antenna mast onto its base receiver section before installing it through screw tightening. Tighten the Antenna mast to 5 n.m (44 lb in) after following the fastener notice in service precautions.

Use tape on the tool surface to protect the paint on the antenna mast from damage.
