Swap a worn or broken 4-prong Navigator tablet mount head in minutes. This guide covers compatibility checks, removal, and installation steps.

Quick answer

To replace a 4-prong Navigator tablet mount head, first verify the replacement matches your mount's arm and tablet size, then remove the old head and install the new one using the same locking mechanism.

Why replace the mount head instead of the whole mount?

If your Navigator mount's arms have cracked or the rotation joint has loosened, replacing just the head is usually cheaper and faster than buying a new mount. The ToughTested 4-Prong Navigator Tablet Replacement Head fits the same arm assembly, so you keep your existing mount base and vehicle attachment.

Before ordering, confirm that your current mount uses the same 4-prong connection. This head is designed for compatible ToughTested mounts, so check the mount model or measure the arm's connector to avoid a mismatch.

What to check before you start

Make sure the replacement head's adjustable arms can hold your tablet's width, especially if you use a thick protective case. The 4-prong design works with many cases, but oversized or unusually shaped cases may not fit securely.

Also verify that the head rotates 360 degrees as expected. If your mount's swivel mechanism is separate, you may need to transfer it to the new head.

Step-by-step replacement process

1. Verify compatibility: Check that your current ToughTested mount uses a 4-prong connector and that the replacement head's arm span matches your tablet's width, including any case. Common mistake: ordering without measuring, which can lead to a loose fit. Measure your tablet's width with the case on before ordering.
2. Remove the old head: Loosen the locking collar or release the tension knob on the mount arm, then slide the old head off. If it's stuck, gently wiggle it while pulling—never force it with tools that could damage the arm. Keep the collar and knob in a safe place; you'll reuse them.
3. Install the new head: Align the new head's connector with the arm's socket, then slide it on until it clicks or sits flush. Tighten the collar or knob to secure it. Common mistake: over-tightening, which can strip the threads. Test the rotation and arm adjustments before mounting your tablet.
