This versatile device was engineered to securely attach to a BMW X3's headrest, providing a convenient spot for an in-car baby monitor. However, its applications extend far beyond that specific use case, making it suitable for attachment to nearly any car headrest or even other locations where a sturdy hold is required. To install it as a headrest mount, simply hook the device onto the headrest rods and tighten with ease.
