GPS tracking is a vital tool for effective fleet management. While some GPS solutions require professional installation, others are far more user-friendly.
Smartrak’s OBD-II is a plug-and-play option that can quickly expand your understanding of fleet performance. But installation is only part of the story. Here’s when swapping an OBD-II between vehicles can be especially useful - and how easy it is to do.

Organisations don’t always roll out telematics across every vehicle at once.
Budgets, scheduling, or priorities often mean installation happens in stages. Typically, the highest-priority vehicles are tracked first, with others added over time.
The OBD-II makes filling those gaps quick and simple. Fleet Managers can plug the device into the standard OBD-II port found in most modern vehicles, register it in Smartrak, and start capturing data straight away. It’s an easy way to extend your tracking footprint without delays.
Many organisations lease rather than own their vehicles, which means fleets are regularly refreshed as leases expire or mileage limits are reached. When vehicles are retired, GPS devices need to transition to replacements.
With an OBD-II, that’s straightforward—just unplug the device from the old vehicle and connect it to the new one.
Organisations may also use OBD-IIs to analyse utilisation and uncover excess capacity. If the data shows too many vehicles, de-fleeting becomes a strategic decision that reduces acquisition and maintenance costs. In these cases, the OBD-II delivers valuable insights before being retired or redeployed.
For large fleets, it’s not always practical to equip every vehicle with a telematics device immediately. Some organisations choose to rotate a smaller number of OBD-IIs across different vehicles over several months. This approach helps build an overall picture of utilisation while keeping upfront investment low.
However, staggered tracking comes with trade-offs. Because vehicles are only tracked part of the time, the data can lack consistency. Important trips may be missed, or outliers might distort results. While this method provides useful insights, it won’t deliver the same accuracy as continuous, fleet-wide tracking.
Whether you’re expanding your telematics coverage, transitioning vehicles during de-fleeting, or trialling staggered tracking, the OBD-II offers the flexibility to adapt as your needs change. Easy to install and simple to swap between vehicles, it’s a smart way to complement your existing fleet tracking solution.
