Use telematics to increase your profitability

Telematics data is all about helping your fleet be more responsive. Knowing immediately when an issue occurs makes you more effective in how you respond—keeping your deliveries on time and avoiding load loss.

It also helps monitor temperature, offers rapid alarm detection and security alerts when the doors are opened, and detects fuel loss.

With ConnectedSuite™ telematics, you have the information you need at your fingertips. Every S-750i unit comes equipped to deliver the data you need, and does so for the first 12 months of ownership with no service charge.
