Garmin eLog: FMCSA Compliant ELD
Features: Simple one-time purchase; No subscription fees. Compliant solution for Hours of Service (HOS) recording that meets FMCSA ELD mandate. Supports 9-pin J1939 and 6-pin J1708 diagnostic ports. Not compatible with vehicles using OBD-II protocol (SAE J1979). Vehicles with Volvo engine and 16-pin J1962 require a separate cable, not included.
Best for: Commercial operators needing immediate FMCSA-compliant ELD without ongoing costs. This option is better for fleets with trucks that use J1939/J1708 ports and do not rely on OBD-II data.
Caution: Some vehicle configurations require additional cables, which are not part of the standard Garmin package. Confirm port compatibility before purchase.
My20 ELD: App-Driven ELD
Features: Most affordable ELD on the market. No additional hardware needed, just your Apple or Android smartphone and the free My20 app. Subscription service required (pre-paid annually). Simple installation with a standard 9-pin (J1939) ECM connector. An adapter cable is required for OBD-II or 6-pin ECM ports.
Best for: Drivers who want a low upfront cost and already rely on a smartphone for app-based logging. Choose this if you’re comfortable managing a subscription and need basic ELD functionality.
Caution: Ongoing subscription costs apply. Ensure your vehicle’s ports can support the required adapter if you don’t have J1939.
PT30 ELD Device: Bluetooth ELD
Features: Easy installation designed for straightforward setup in compatible commercial vehicles. Bluetooth connectivity communicates with compatible mobile devices and ELD applications. Engine data connection provides vehicle data to compatible ELD software.
Best for: Operators seeking a Bluetooth-enabled ELD that pairs easily with mobile apps and supports real-time engine data. It’s a solid pick for newer fleets prioritizing modern wireless setup.
Caution: Availability of Bluetooth features depends on vehicle wiring and compatible ELD software used with the device.
IOSIX ELD Mandate: Built-In 9-Pin ELD
Features: Built-in 9-pin form factor—no cable required for 9-pin installs. Includes a connector for other vehicle port types. Compatible with J1939, J1708/J1587, and OBD-II protocols, Broad vehicle compatibility. FMCSA-certified electronic logging compliance with a built-in 3-axis accelerometer for driving behavior analysis.
Best for: Fleets and solo drivers needing flexible port compatibility and a cable-free 9-pin installation. Ideal for mixed-portfolio vehicles needing FMCSA compliance with multi-port support.
Caution: For non-9-pin ports, ensure the included connector fits your vehicle’s connector type to avoid installation delays.

Features: 8-inch truck GPS tablet with built-in dash cam, advanced truck routing, lane guidance, Bluetooth, Wi-Fi, and powered magnetic mount. Includes a rugged mount with FM transmitter, 3W speaker, and embedded SiriusXM receiver for audio playback. Truck-specific routing data helps avoid low clearances and restricted roads.
Best for: Drivers seeking an all-in-one device that combines navigation, routing, dash cam, and in-cab entertainment features. Particularly well-suited for long hauls and fleets needing consolidated hardware.
Caution: This is a multi-function device; ensure you’re comfortable with using a tablet-based interface for ELD logging in addition to navigation and cam features.
Buying Guide
What matters most when choosing an ELD for semi trucks? Consider port compatibility (J1939, J1708, OBD-II), whether you need a built-in device or a smartphone-based solution, and if there is a subscription cost. Assess installation simplicity, data integration with your fleet management software, and whether additional features like dash cams or routing improvements justify the cost.
Port compatibility: If your trucks use J1939 or J1708 ports, look for devices that explicitly list support. OBD-II only devices may not work with some heavy trucks.
Subscription vs. one-time purchase: Some ELDs require ongoing subscriptions, which impact long-term costs. Others are one-time purchases but may lack cloud-based features.
Ease of installation: Bluetooth and plug-and-play options reduce downtime. For fleets with mixed vehicles, a flexible port and connector kit can save time.
Additional features: Dash cams, advanced routing, and engine data integration can add value beyond compliance. Weigh these features against the price and your operational needs.
Compliance and data handling: Ensure the device is FMCSA-certified and supports standard HOS reporting. Data accessibility for audits is also important.
