5. Cover the trunk floor to catch debris from drilling.
B. Drilling the hole in the trunk lid for the 2nd Generation SDARS antenna
1. Measure and mark (Arrow, Figure 1) the trunk lid underside at the center of the recessed hole in the reinforcement panel.
2. Apply masking tape covering an area approximately 8 in. x 8 in. on the trunk lid exterior where the antenna will mount.
3. From the trunk lid underside, drill a 3 mm diameter pilot hole at the measured mark in the recessed hole in the trunk reinforcement panel.
CAUTION
Drilling metal can cause airborne metal debris. Airborne metal debris can cause serious injury to the eyes. Use protective eyewear.
NOTICE!
Improper or careless drilling can damage metal surfaces. Paint or body damage to the trunk lid can result. Exercise care and accuracy when drilling.
4. Drill the 3 mm pilot hole to an enlarged 6 mm diameter pilot hole.
5. Drill the 6 mm pilot hole to a 14 mm diameter hole using a UniBit(R).
NOTICE!
Using a hole saw is not suitable for drilling the hole in the trunk lid.
Using a hole saw will damage the trunk lid.
Do not use a hole saw to drill the trunk lid.
6. Remove the burrs around the hole edge and carefully clean away the metal debris from the trunk lid.
7. Remove the tape from the trunk lid and the cover with debris from the trunk floor.
8. Thoroughly coat the 14 mm diameter hole edge with primer and follow the approved manufacturer's recommended drying time.
C. Installing the 2nd Generation SDARS antenna
1. Loosen the T25 Torx screw (A, Figure 2) in the antenna sleeve.
2. Feed the antenna lead (B, Figure 2), from the top side of the trunk lid, through the 14 mm hole.
3. Carefully insert the SDARS antenna sleeve into the l4mm hole until it audibly engages.
NOTICE!
Applying force to body panels can result in damage. Excessive force will dent the trunk lid. Do not use excessive force when inserting antenna sleeve into the 14 mm hole.
4. Align the SDARS antenna straight with the vertical end (A, Figure 3) facing the vehicle front and the beveled end (B, Figure 3) the vehicle rear.
5. Apply light downward pressure to the SDARS antenna so to the gasket fully seats flush against the trunk lid.
NOTICE!
Applying force to body panels can result in damage. Excessive force will dent the trunk lid. Do not use excessive force when seating the antenna gasket to the trunk lid.
