The SmartNav system contains other helpful features for driver safety and convenience. The truck monitoring feature provides real-time data like fuel flow rate, air pressure, temperature, as well as auxiliary transmission oil temperature, and trailer reservoir air pressure. It has four camera ports, allowing drivers to install and access video from up to four cameras.
