Charge Groove (Standard)

Step-by-step installation instructions for the standard 5-piece Charge Groove. Find detailed information on how the friction-fit system snaps into the factory dashboard gaps without tools.

What parts are included when I receive the standard Charge Groove?

The package contains 5 structural 3D-printed parts (1 Center Piece, a Left & Right Body, and a Left & Right Wing). It also includes 4 assembly screws (2 longer ones for the center, 2 shorter ones for the wings), an installation hex key, and a plastic trim tool.

Do I need to assemble the standard Charge Groove before putting it in the van?

No. Unlike the XL version, the standard Charge Groove is assembled directly inside the vehicle piece by piece. You do not build it on a workbench beforehand.

How do the main body parts stay securely in the dashboard without drilling or screws?

The system utilizes a precise friction-fit design. The front lip of the left and right body parts nests directly into the factory gap of the Mercedes dash. Once the front is nested, pressing the rear section down locks the bodies firmly into the factory groove.

What is the included plastic trim tool used for?

Depending on factory manufacturing variances, the gap in your Mercedes dashboard can be quite tight. The plastic trim tool is included so you can gently pry open the gap to slide the front lip of the Charge Groove bodies into place without scratching your dash.

Where do the different screw sizes go during the installation?

The 4 screws are used to lock the separate pieces together once they are seated in the dash:

  • The 2 longer screws secure the Center Piece to the main bodies.
  • The 2 shorter screws attach the Left and Right Wings to the outer sides.

Charge Groove XL

Complete assembly instructions for the 7-piece Charge Groove XL. Find detailed information on how to build the bolted chassis and secure it using your vehicle's existing factory T20 mounting locations.

What parts are included when I receive the Charge Groove XL?

Your package includes 7 structural 3D-printed parts (1 Center Body, 2 Outer Bodies, 2 Wings, and 2 Mounting Blocks), 8 assembly screws with 8 matching square nuts, an installation hex key, and 2 vehicle mounting screws. Optional: You can add our T20 key to your order if you don’t own a Torx T20 driver.

Why do the screws feel tight when I first start assembling the 3D-printed body parts?

We intentionally print precise threads directly into the first sections of the plastic components. These built-in threads act as a natural lock. They create intentional resistance to ensure the Charge Groove never rattles apart from heavy vehicle vibrations on the trail.

Is there a trick to getting a perfectly seamless alignment during assembly?

Yes. When attaching the wings and outer bodies, do not tighten the screws completely right away. Leave them slightly loose, slide the components into their precise flush position on a flat surface, and then do the final tightening. (Note: Having a helper hold the mounting blocks in place while inserting the square nuts makes the process even easier!)

Why is my factory dashboard lid sticking up slightly after installing the Charge Groove?

The fit is engineered to exact tolerances based on high-precision 3D scans of the vehicle. If your dashboard lid doesn't close completely flush after installation, it means the Charge Groove parts are slightly pinched or misaligned in the corners. To fix this, simply loosen the mounting screws, push the entire Charge Groove firmly forward toward you, and re-tighten the screws. This ensures the factory lid can close perfectly.

Navidok Overlander X

Find detailed data regarding the mechanical lower wedge mechanism, the adhesive curing times for the upper brackets, and proper disassembly procedures.

What installation hardware is included with the Navidok Overlander X?

Your package includes the Navidok Overlander X main unit, two upper mounting brackets with pre-applied heavy-duty double-sided tape, an alcohol prep pad, and the required assembly hardware (2 washers, 2 screws, 2 square nuts, and two hex keys: 3/32" and 5/32").

Why does the installation process require masking tape and a "dry fit"?

Because we don't want you to guess the alignment. You first mount the system loosely without exposing the adhesive tape. You then use masking tape to mark the exact position of the upper brackets on your dash. After marking, you remove the unit, clean the area, and stick the brackets down perfectly straight based on your tape lines.

What is the most critical step when prepping the dashboard surface for the upper brackets?

Cleanliness is key. You must use the provided alcohol wipe to clean the surface area thoroughly. If you have ever used plastic conditioners, cockpit sprays, armor-all, or interior polishes, they leave a slick residue that must be completely stripped off, or the automotive tape won't bond.

How long do I need to wait after installing the upper brackets before hitting the road?

The heavy-duty adhesive tape requires an activation and curing time to achieve its full strength. It reaches a 50% bond after 30 minutes, 90% bond after 24 hours, and 100% bond after 72 hours. We strictly recommend letting the brackets cure for at least 24 hours before mounting your heavy devices or hitting rough trails.

How tightly should I fasten the lower and upper mounting screws?

Do not overtighten any of the screws. For the lower brackets, push the Overlander X against the dash and turn the screws until you feel them "grab" and tighten up. The same applies to the upper screws: give them a light turn until they grab and the unit is securely locked into the brackets.

Overlander

Complete installation and removal instructions for the Navidok Overlander. Find detailed information on how to prepare the dash surface, apply the retention strips, and securely lock the wedge bracket chassis in place.

How do I prepare the dash and the Overlander before mounting?

First, pre-position the Overlander on your dash to test the exact fit, then remove it. Separate your hook-and-loop strips and stick the rough "hook" side directly onto the designated spots on the bottom of the Overlander, then place the soft "loop" side back on top. Finally, use the included alcohol wipe to thoroughly clean the vehicle's mounting surface and let it dry completely.

How do I properly align and secure the Overlander?

Peel the backing covers off the exposed loop strips. Ensure the built-in locking wedges are pulled back completely flush with the main bracket so the unit can slide into place without catching. Position the dock flush against the dash, press down firmly to set the adhesive strips, and use the included Allen key to tighten the retention screws on both sides until the dock resists wiggling. Note: Do not over-tighten.

How do I attach my phone and accessory mounts to the dock?

Slide your accessory base into the Overlander track and tighten it down. When attaching a double-socket arm to the mounting ball, ensure the closed/clamping section of the arm captures the ball securely before positioning your device cradle.

How do I safely remove the Overlander from the vehicle?

To take the dock off, completely loosen the retention screws on both sides with your Allen key and push the screws all the way forward to release the internal locking wedges. Because the heavy-duty adhesive strips create a tight bond, give the Navidock a firm, steady pull to release it from the dash.

Visordok

Complete installation instructions for the Sprinter Visordok. Find detailed information on how to remove the factory visor clips and secure the dock chassis using a T30 torx driver.

What tools are required for the installation?

To install the Sprinter Visordok, you will need a T30 screwdriver (Torx) to remove and reinstall the main mounting screws, and a small flathead screwdriver to pop out the factory plastic clips.

How do I safely remove the factory sun visor?

First, unclip your sun visor from the plastic clip, pull it down, fold it back, and slide the visor out of the way. This gives you clear, unobstructed access to the factory mounting hardware hidden inside the recess.

How do I remove the factory mounting screws and plastic clips?

Use your T30 screwdriver to completely back out and remove the factory screw. Next, take your small flathead screwdriver, insert it into the recess, and gently push back on the plastic retention tab. Once pressed, the factory plastic clip and its mounting knob will pop right out.

How do I position and align the Visordok for installation?

Take your Visordok and hold it up to the overhead console, aligning its pre-drilled mounting slots directly over the two factory holes you just cleared.

How do I secure the Visordok to the vehicle?

While holding the Visordok in position, insert the first included screw into the slot and start tightening it down with your T30 screwdriver. Repeat the process for the second screw, ensuring both are torqued down firmly so the dock is completely set and ready for accessories.

Cupdok

Complete assembly and installation instructions for the Terra X Cupdok. Find detailed information on how to build the wedge chassis and lock it securely into your vehicle using our adjustable mounting block system.

How do I prepare the stabilization wedge before installation?

Slide two of the large square nuts into the wedge slots (you can use a hex key to push them into alignment with the holes). Position the wedge onto the Cupdok so that its lower point slopes toward the back, away from the front edge. Insert the two larger screws and tighten them by hand just enough so the wedge can still slide, then push it all the way to the back.

How do I assemble the two mounting blocks safely?

Slide a square nut into the back of each mounting block until it aligns with the hole. Next, thread the pointed set screw into the block with the sharp point facing downwards. Crucial: Stop screwing once the sharp tip reaches the upper edge of the block—if the point extends past the edge, it will scratch your Cupdok when you try to slide it into place later.

How do I seat the Cupdok and position the mounting blocks inside the vehicle?

First, use the large (5/32) hex key to slightly loosen the pre-installed ring screws just a hair so they can move. Make sure the large wedge is pulled all the way back, then set the Cupdok into its place in the vehicle dash. Take your prepared mounting blocks and slide them into the dock slots—Alex recommends sliding them down to align with the third square slot on each side.

What is the correct sequence for tightening everything down?

  1. Use the small hex key to tighten the mounting block set screws just until they bite into the metal and stop sliding.
  2. Push the Cupdok firmly down, shove the large stabilization wedge as far forward into the gap as possible, and tighten the wedge screw completely with the big hex key.
  3. Fully tighten the two main pre-installed mounting ring screws.
  4. Go back to the mounting blocks and torque the small set screws all the way down until they lock tight.

Ford Transit Navidok

Get your Ford Transit Navidok securely mounted and perfectly aligned with these straightforward, step-by-step instructions.

What comes in the kit and why is it shipped pre-assembled?

The Navidok ships with the mounting blocks already attached to the upper brackets so you can get a visual reference of exactly where they need to sit during installation. The kit also includes a hardware bag with four foam pads and one hex key. Note that the blocks are stamped on the inside with "DS" (Driver Side) and "PS" (Passenger Side) so you don't mix them up.

How do I prepare the mounting brackets before moving to the vehicle?

First, you need to apply the included protective foam pads. Peel the backing off and place one pad high up on the mounting bracket, and place a second pad lower down on the bottom. Repeat this for the second bracket. Once padded, use your hex key to completely unscrew and remove both the mounting blocks and their screws from the unit.

How do I properly position the Navidok and the first mounting block?

Center the main Navidok chassis on your dash and simply drop it into place—do not force it. Starting on the passenger side, grab your "PS" block. Lift the Navidok bracket up just a hair and slide the block into the forward square recess until it sits perfectly flush with the edge.

How do I secure the first mounting block without locking the unit in place?

Drop the first screw straight down into the top hole. Insert your hex key—it should drop down about 1.5 inches when the screw is properly seated in the block. Turn the key a maximum of two times to catch the thread, but leave it loose! You need this slack to fit the other side. Crucial Note: If the block falls out while the screw is inside the hole, you cannot simply force it back in. You must pull the entire Navidok out, remove the screw, and repeat the process.

How do I install the driver side block and finalize the installation?

Move to the Driver Side (DS) and verify that the screw hole on the block is facing the inside. Just like the other side, lift the unit slightly, nest the block into the front recess, and slide it flush. Drop the second screw into the hole and use your hex key to fully torque it down tight. Finally, return to the passenger side and tighten that first screw completely.

Ford Transit Visordok Tubetrak 

Get your Visordok Tubetrak perfectly assembled and locked into your Transit's overhead console with these step-by-step instructions.

What tools and hardware are required for the installation?

To fully assemble and install the Tubetrak, you will need the included hex key, a T20 Torx screwdriver, a Phillips head screwdriver, a 7 mm (or 9/32") socket wrench, and a sharp tool like a putty knife or butter knife. Your kit ships with the main tube track, a right and left bracket, two 1/4-20 screws, two square nuts, two long #10 screws, and two short #8 screws.

How do I pre-assemble the track tube and brackets on the bench?

Lay the tube flat on your table with the Terra X logo pointing towards you. Wiggle the two square nuts into the track until they drop into place. Lay the left and right brackets on their flat sides, ensuring the open side of each bracket faces inward. Slide both brackets into the tube ends, align them with the square nuts, insert the 1/4-20 screws, and tighten them down evenly with the included hex key.

How do I prepare the vehicle's overhead console for installation?

Unclip the sun visor to move it out of your way. Take your putty knife or sharp tool and carefully pry off the plastic cap on the front console recess (don't worry if it's stiff; this area will be covered up by the bracket). Next, use your T20 screwdriver to remove the factory visor clip screw, and use your 7 mm socket to back out the main factory chassis screw. Repeat this entire teardown process on the passenger side.

Where do the different included mounting screws go?

The kit includes two different sets of screws for the vehicle installation, and mixing them up will cause fitment issues:

  • Short #8 Screws: These go into the mounting holes closest to the sun visor clips.
  • Long #10 Screws: These go into the forward mounting holes where the factory plastic caps used to be.

How do I mount and secure the Visordok to the vehicle?

Hold the fully assembled Visordok up to the ceiling, lining up the bracket slots with the cleared factory holes. Drop a short #8 screw into the visor clip side of the bracket, grab your Phillips head screwdriver, and thread it in loosely. Repeat this on the other side. Finally, insert the longer #10 screws into the front holes of both brackets and torque all four screws down firmly until the unit is rock-solid.
