Follow the instructions on the product label.

IMPORTANT:

The RF connections for the inner antenna coupling should run parallel to the defogger gridline.
Align the inner and outer antenna couplings.
Do not touch the adhesive backing on the antenna coupling.

If the exterior coupling is not installed, mark the inner antenna coupling locations with a grease pencil on the exterior surface of the rear window.
- Location (A) 115 mm (4.5 in)
- Location (B) 115 mm (4.5 in)
Remove the protective film from the adhesive backing on the inner antenna coupling.
Align the inner antenna coupling to the locating marks on the back glass or the exterior coupling.
Press firmly on all 4 corners and on the center of the inner coupling (2) in order to ensure proper adhesion to the glass (4).
