How to replace the navigation antenna on 2004 Buick Regal?

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.
