Navistar logo Navistar logo Zonar and Navistar, together at last.

Two leaders team up to deliver deep vehicle data.

Navistar is renowned for its IC Bus® lines and its series of International® Trucks, one of the most trusted brands in the industry. Navistar sets the standard for quality fleet vehicles. Zonar sets the standard for quality, comprehensive data sets for vehicle monitoring and maintenance. We also have the deepest integration through our longstanding history and experience with OEM partnerships—and the highest number of telematics control units (TCUs) in select Navistar vehicles.

This partnership delivers richer, deeper data so you can more efficiently manage your Navistar vehicles from the inside and out. Premium vehicles, quality data, greater operational efficiency.

On board with OnCommand® Connection.

Having a mixed fleet often means using more than one diagnostic system to monitor and manage your vehicles. OnCommand Connection links an entire fleet with one portal—all makes, all models—to streamline operations. And Zonar TCUs serve as access points for OnCommand Connection to retrieve vehicle data. Through this partnership, Zonar customers can use OnCommand Connection to access the comprehensive diagnostic data pulled through Zonar TCUs across their mixed fleet.

Tap deeper into your Cummins engines.

More than half of Navistar’s International Trucks and IC Buses vehicles run on a Cummins engine. And Zonar is a participating telematics provider for Cummins Connected Diagnostics™ with Connected Advisor™. Our TCUs connect directly to the vehicle’s engine control unit to seamlessly transmit fault data to Cummins for expert analysis.
