Overview: The Cam Lock Installation Kit is designed
specifically to mount the OnStar FMV to the windshield of compatible vehicles
that use a cam lock mounting system to secure the factory rearview mirror. The
Cam Lock Installation Kit consist of the following:
- Cam lock installation bracket
- Tube of 1-step glass primer
- 2 Dual self-adhesive syringes
- 2 Alcohol prep-pads
- Installation Instructions
Removing Factory Mirror: Grasp the base of the mirror and rotate
90-degress counterclockwise. Slide the mirror down toward the dash to remove. No
tools are required.
Cleaning & Prepping Windshield: Scrape the windshield with a razor
blade to remove any residue or contaminates (maybe clear and not visible to the
naked eye). With the provided alcohol wipes, thoroughly clean the glass mounting
area. Then apply primer to this area of the windshield (keep dashboard covered
to catch drips and prevent staining). Allow a minimum of 6 minutes for primer to
dry before applying the adhesive.
Installing Cam Lock Mount Adapter: Slide the cam lock adapter up into
the factory cam lock mount on the windshield of the vehicle. Ensure the adapter
is seated all the way up into the mount. Hand tighten the set-screw using a
1/64" Allen wrench. Apply electrical tape along the sides and top of the mount
adapter; use a flat-edged tool to make a tight seal between the tape and
windshield to keep adhesive from squeezing out when injecting the adhesive.
Note: If the adapter starts to push away from the windshield, it
is too tight.
Applying Adhesive: Using only the adhesive provided, insert the
syringe into the fill holes at the top of the adapter and slowly depress the
plunger. The cam lock installation kit includes 2 dual syringes. Cover the
dashboard to avoid damage from drips. The adhesive starts to set within 5-10
minutes of applications. After 10 minutes, you may mount the OnStar FMV Mirror.
Note: Allow at least 20 minutes for the adhesive to fully cure at
room temperature before driving the vehicle.
