The Apri KBSS-4D Parking Assistant is a front and rear ultrasonic sensor system that aids parking and reversing by detecting obstacles and displaying numeric distance on a LED display. The system uses four ultrasonic sensors to measure proximity and presents distance information on a numeric LED readout for quick driver reference.

The unit issues progressive buzzer alerts that increase in frequency as distance to an object decreases. It is suitable for SUVs, bakkies and vehicles without factory-fitted park assist systems and includes all necessary components for installation. Professional installation is recommended to ensure correct sensor alignment and wiring.
