Align the outer antenna coupling to the inner antenna coupling.
Press firmly on all 4 corners and on the center of the antenna outer coupling (5) in order to ensure proper adhesion to the back glass (4).
Hold pressure on the outer coupling (5) for 10-30 seconds.
Ensure that no gaps occur between the couplings (5, 2) and the back glass (4).
Keep the vehicle dry. Allow 6-8 hours, at 15°C (60°F), for the adhesive to cure after installation.
