PRE-INSTALLATION CONSIDERATIONS
• Do not install if air temperature is below 600 F.
• Integrity of the installation will be compromised if one or more of the following are present
at the planned installation location:
1. Rain XTM or other commercial water repellant.
2. After market window tinting material.
If present, remove material or select a different location before installing.
• Receiver location cannot be more than 12 feet from antenna.
• Avoid locations with curved glass (typically close to windshield edge)
CAUTION: For front windshield installation, select location on passenger side as far
from the glass edge as possible and away from windshield wiper path.

LOCATION AND GLASS PREPARATION
• Mount as high on glass as possible for optimal performance.
• Driver visibility should not be obstructed in any manner.
• Identify location of installation. Select a location that allows for interior headliner clearance.
Allow for windshield wiper clearance if present. Using the glass curvature card, test for
nearly flat (non-curved) surface.
• Thoroughly clean with provided alcohol pads only. (Isopropyl alcohol can be used for
rewetting the pads.) Do not use WindexTM or other commercial cleaners.
• In order for adhesive to properly adhere to exterior glass surface, the surface of the glass
should be nearly flat. Check for curvature of glass using the card template provided. Hold
down the card from one end against the surface and look for any gaps (see below). There
should be no gaps between the template and the glass surface.
• Test for curvature twice: along the length of the vehicle and along the width of the vehicle.

INSTALLATION OF EXTERIOR UNIT
• Make sure you have read the previous sections about glass location and preparation.
• Position the alignment template to exterior windshield location with the printed side
pressed against the glass. Hold in place using masking tape.
• Verify correct installation by viewing from inside of the vehicle. Check that there are no
defogger wires in the areas indicated on the templates. (see figure below)
CAUTION: Do not install the interior unit yet!
