Solid RoadVise® Phone Holder

The holder also features a specialized recess for the Apple MagSafe Charger or other Qi wireless chargers, providing a secure and convenient way to keep your device charged during your travels.

Flexible Gooseneck Arm

This car and truck phone mount features an 18" adjustable gooseneck, offering complete flexibility in positioning your phone for optimal viewing on your road trip.

Built from durable ridged aluminum, the gooseneck firmly stays in place, making it the ideal mount tool for using your device for GPS use or hands-free calls. For added stability, it includes a metal conduit that braces against the car's console to minimize vibrations (screws not included).

Additional Composite Shaft for Fine-Tuning

The 3.75" Robust™ mount shaft, sitting between the holder and gooseneck, offers precise adjustments to perfectly align your device.

Additionally, the shaft ball end allows for a full 360° rotation, making it easy to switch between horizontal and vertical placement.

Strong Seat Rail or Floor Mount

The RoadVise® Ultra Holder with Shaft Arm and 18" Seat Rail Mount arrives with seat and rail brackets, making it an alternative to windshield or dash mounts. 

It keeps your dash, console, and windshield free from clutter.

Straightforward Seat and Floor Fitting

Installation is simple: Use a socket wrench to secure the mount's reinforced bracket to the car's seat rail or utilize the included floor brackets for direct attachment to the vehicle's floor. 

If drilling is necessary, consult an auto professional to avoid damaging any sensitive components beneath the floor.
