Fleet management today isn’t just about tracking your vehicles’ locations; it’s about ensuring your entire operation runs smoothly. When every minute of downtime eats into margins and every gallon of fuel burned shows up on the balance sheet, the way you track and manage your fleet becomes a significant concern.
Consider this: a delivery van stuck in traffic, an unexpected breakdown on the highway, or even a missed maintenance alert can lead to late deliveries, unhappy customers, and increased costs.
That’s why GPS fleet tracking has become less of a “nice-to-have” and more of a standard operating tool. The real question for most fleet managers today isn’t whether to use tracking, but which type of tracking makes the most sense.
The two leading options?
- OEM-Integrated Fleet Tracking, which comes factory-installed in new vehicles.
- Aftermarket GPS Systems, which are added later through third-party providers.
Both can help you reduce downtime, improve safety, and make smarter decisions, but the right fit depends on your fleet size, age, and operational priorities.
In this blog, we’ll break down the benefits and trade-offs of each, and show you how a unified solution like EcoTrack Fleet Management can bring the best of both worlds together.
What Is OEM-Integrated Fleet Tracking?
OEM (Original Equipment Manufacturer) fleet tracking is typically installed directly by vehicle manufacturers during the manufacturing process. That means there’s no need for third-party hardware or extra installations. Once the vehicle is delivered, it’s “connected” and ready to start sending data.
Main Features
- Seamless Integration: Because it’s factory-installed, OEM tracking communicates directly with the vehicle’s native systems (engine diagnostics, odometer, fuel consumption, EV charging data).
- Faster Deployment: Vehicles are online and ready to be managed from day one, with no downtime for device installation.
- Warranty & Support: OEM systems are supported by the vehicle manufacturer, ensuring data accuracy and reducing compatibility issues.
- Green Fleet Advantage: Particularly valuable for fleets shifting to EVs, as OEM systems often provide charging status, battery health, and range data.
Limitations
- Restricted to New Vehicles: Legacy fleets or mixed fleets cannot take advantage of this offer without purchasing new, OEM-equipped models.
- Dependency on Manufacturer Updates: Since the system is tied to the OEM, fleets rely on the vehicle manufacturer for software updates, bug fixes, and feature enhancements. This dependence can sometimes result in slower updates compared to aftermarket solutions, as the OEM controls them.
- Impact of Vehicle’s Internal Systems on Data Transmission: The data from the vehicle is transmitted to the mapping platform through the vehicle’s internal computer system, not just the OEM device. Any issues with the vehicle’s internal hardware can affect the data sent to the software, potentially impacting functionality. While software updates may affect the vehicle’s internal systems, they don’t necessarily impact the OEM device itself, but could still influence overall performance.
- Data Privacy Concerns: OEM telematics often transmit vehicle and driver data back to the manufacturer. This can raise concerns about who owns the data, how it is stored, and whether fleets have complete control over usage and access.
- Limited Flexibility: Customization and cross-brand standardization can be more challenging if your fleet includes vehicles from multiple manufacturers.
OEM solutions are ideal for fleets that regularly refresh vehicles every couple of years, prioritize minimal downtime, and want built-in reliability.
What Is Aftermarket GPS Fleet Tracking?
Aftermarket GPS systems are installed after purchase, either by the fleet operator or through a service provider. These devices can be hardwired into vehicles or connected via plug-and-play OBD ports.
Main Features
- Broad Asset Coverage: Aftermarket solutions can be installed not only in vehicles but also in trailers and heavy equipment, giving fleets complete visibility across all asset types. In contrast, OEM solutions are generally limited to vehicles only.
- Customizable Features: Add advanced driver behavior monitoring, dashcams, cargo sensors, or geofencing according to your needs.
- Scalability: Easily add or remove devices as your fleet evolves.
- Vendor Ecosystem: Many aftermarket providers (like EcoTrack) offer integrations with dispatch, payroll, and compliance platforms.
Limitations
- Installation Downtime: Vehicles may need to be taken offline temporarily for hardware installation.
- Maintenance of Devices: Physical hardware can fail, become outdated, or need upgrading.
- Vendor Dependence: Fleet performance and insights depend on the chosen provider’s technology and support quality.
While OEM solutions may limit visibility to vehicles from a single manufacturer, fleets can overcome this by working with aftermarket vendors like EcoTrack. These platforms enable the simultaneous display of mixed fleets, utilizing both OEM-integrated and hardwired devices, on a single mapping system, ensuring comprehensive visibility of the entire fleet.
OEM vs. Aftermarket: Side-by-Side Comparison

| Compatibility | Limited to new, OEM-supported models | Works across mixed and older fleets |
| Upfront Cost | Newer (models as latest as 2020 and sooner) vehicle cost, but no separate device expense | Lower upfront, but hardware and installs add costs |
| Flexibility | Fixed feature set from manufacturer | Highly customizable with sensors, add-ons |
| Support & Reliability | Backed by OEM warranty | Depends on provider and hardware |
| Scalability | Scales with new fleet purchases | Scales easily across all vehicle types |
Key Considerations Before Choosing a Fleet Tracking System
Deciding between OEM-integrated fleet tracking and aftermarket GPS isn’t just a technical choice; it’s a business decision tied to your operations, budget, and growth strategy.
- Fleet Age & Composition: If your vehicles are mostly brand-new models from a few select manufacturers, OEM tracking can save you time and deployment headaches. However, if your fleet includes older trucks, mixed makes, or specialized vehicles (such as trailers or heavy equipment), aftermarket systems offer the necessary compatibility. Many fleet management platforms also enable you to integrate OEM and hardwired aftermarket devices on the same system, providing unified visibility across your entire fleet.
- Downtime Tolerance: OEM tracking is “ready to go” at delivery, while aftermarket systems require installation. For businesses where every hour counts, such as those in delivery or logistics, minimizing downtime may tip the scales in favor of the OEM.
- Data Needs: OEM solutions can deliver extensive vehicle data directly from the onboard computer, including odometer readings, fuel consumption, EV charging status, seatbelt usage, harsh driving events, and even airbag deployment. In many cases, OEM devices can also support features like geofencing, driver safety monitoring, and dashcam integration, depending on the software. Aftermarket systems, however, often provide greater flexibility in customization, allowing fleets to add sensors or specialized options that may not be included in OEM packages.
- Cost & Scalability: Upfront costs for OEM tracking are included in the vehicle price, whereas aftermarket systems require additional hardware investment. However, aftermarket solutions scale faster across diverse fleets without waiting for new vehicle purchases.
By weighing these factors, fleet managers can align their choice with long-term goals, whether it’s maximizing ROI, enhancing safety, or preparing for electrification.
Now, let’s get to what you should zero in on. The following section will help you understand that.
