Four steps to get started
Review the hardware, app and account together, then learn the daily workflow.
Choose an Auto Agent and a cable that match your vehicle's diagnostic connection. Share your truck and port details with HDTruckTunes if you need a hardware review.
Use a compatible iOS or Android phone or tablet with cellular data, and install the EZ LYNK ELD app. Check the provider's current device requirements.
Create a Fleet Manager account, add your drivers and assign the Auto Agent serial number to the provider plan you choose.
Review EZ LYNK's guides for logs, inspections and data transfer before using the system on the road.
Driver and fleet tools
EZ LYNK connects vehicle data, the driver's ELD app and the Fleet Manager portal. Available features depend on the provider plan you select.
Record duty status, review driving time and present or transfer logs during an inspection.
Create inspection records in the mobile app and review them through the fleet portal with a supported plan.
Supported plans bring fuel receipts and mileage information together for IFTA reporting.
Manage drivers and vehicles, review records and communicate through EZ LYNK's cloud tools.
Match the connection
An Auto Agent, the right diagnostic cable and a compatible mobile device work together. Hardware purchases and the EZ LYNK subscription are separate.
