Quick Start Guide

Updated on Mar 4, 2026

 You can find more information about the cable loom in the complete user guide.

When installing the VBOX 100 Hz GPS Speed Sensor (v5) in your vehicle, you can either fix it rigidly to the vehicle using the fixing holes or secure it with a telescopic mounting arm.

Try to position the unit as close to the centre of the vehicle as possible, and make sure that it is level with the ground. 

Note: The VBOX unit and the antenna should be mounted on the same rigid body to provide a relative reference. So for a vehicle such as a truck cabin, both the VBOX unit and the antenna should be fitted to the cabin body (if the cabin is air-sprung) or to the vehicle chassis.

Note: It is important that you do not use force when connecting and disconnecting the loom to the VBOX unit.

Push the connectors gently together and twist the outer ring on the loom's connector until it slots in place and locks the connection.

Note the notches on the connectors as illustrated above. Twist the loom's connector while you gently pull it away from the unit.
