Installation of the Grenadier (2024+) Base

Before beginning, please read all instructions thoroughly. Allow between 5 to 15 minutes to complete the installation of the Grenadier (2024+) dash base. 

Step 1: Dry Fit the Base

  • Without exposing the adhesive yet, place the base on the OEM dash where it fits, either the left or right side, based on your order. Position it slightly above or just touching the soft OEM dash material. Observe the hole locations and the general area where you will apply 3M® Blue painter's tape for the next step.

Step 2: Add Blue Tape to the Grenadier unit and mark the pilot hole locations.

  • Remove the base and set it aside. Apply the 3M® Blue painter's tape to the area where the holes will go. Reposition the base as in the dry fit. While holding it in place, use a Sharpie to mark the hole locations on the tape. Then remove the base again.

Step 3: Carefully drill pilot holes for the fasteners.

  • Using a 2.5mm or #46 drill bit, carefully drill two small pilot holes in the four marked spots. We recommend using a small drill chuck to manually drill through the soft dash material. Afterward, remove the painter's tape and clean the area.

Step 4: Remove the 3M® liner from the adhesive and set the base.

  • Remove the red liner from the pre-installed adhesive pads, exposing the adhesive. Carefully align and attach the base to the dashboard, matching the orientation and pilot holes established during the dry fit. Ensure accurate placement, as repositioning will weaken the adhesive bond. Install the fasteners, tightening them slowly and carefully without over-tightening.

Step 5: Install the fastener and let the 3M® brand VHB setup for 24 hours.

  • Do not install clamps, bolts, knobs, arms, or holders yet. Leave the base untouched for at least 24 hours (ideally 72 hours) to allow the 3M® VHB adhesive to bond properly.

  • 3M® states that:

    • 50% of the bond strength is achieved after 20 minutes,
    • 90% after 24 hours,
    • 100% after 72 hours.

    Also, ensure the interior temperature is at least 60ºF (16ºC) during installation, as recommended by 3M®

    Also factor in the temperature you are working in. 3M® published this:

    "...the lowest temperature for the interior components that you are mounting 67 Designs bases to is a minimum of 60ºF (16ºC)."

      Step 6: After 24 hours, add the clamps, arm and holder.

      • After 24 hours, you may install the clamps, Ball2Ball™ arm, and the 67 Designs device holder. Always loosen the knob on the clamps before moving or adjusting any components. This system requires you to loosen, adjust, and then retighten the parts. Failure to do so may damage the base and void the warranty. For additional accessories like the GoPro holder, attach them as needed.

      • *If alignment or bonding issues arise in Step 4, contact Customer Service for replacement adhesive.
