OBD vs. hard-wired GPS unit – a comparison
When choosing tracking you run into the dilemma of OBD vs. a hard-wired GPS unit. Both types have their place, but they differ in fitting, reliability and resistance to tampering. In this comparison we explain the differences so you choose correctly.
How the two types of GPS unit work
In the OBD vs. hard-wired GPS unit debate, what matters above all is the method of connection. An OBD unit simply plugs into the vehicle's diagnostic connector and is working within moments. A hard-wired unit connects directly to the on-board wiring.
Both types provide the position and basic trip data. The difference lies in how firmly they are seated in the vehicle and what additional functions they allow.
The OBD unit – benefits and limits
The biggest benefit of an OBD unit is simplicity. You can fit it yourself, with no intervention in the wiring, and move it easily to another vehicle. That is practical for short-term tracking or for cars you change often.
The limitation is that the OBD connector is visible and the unit can be pulled out fairly easily. For theft protection, or for tracking where resistance to tampering matters, it may therefore not be ideal.
The hard-wired unit – benefits and limits
A hard-wired unit is fitted out of sight and powered directly from the on-board supply. It is more resistant to tampering, harder to find and provides a more stable connection. That makes it the better choice for long-term fleet tracking and theft protection.
The drawback is that fitting should be done by a professional, and the unit becomes a fixed part of one particular vehicle. That small initial investment repays itself in higher reliability and security.
Which type suits you better
If you need a quick, temporary solution that you move between vehicles, go for OBD. If what you want is long-term, reliable tracking of a fleet with an emphasis on security, a hard-wired unit will serve you better.
SaveTrack uses proven Teltonika units, which are available in both variants. Depending on the type of vehicle and the purpose, we will advise which solution works out best for you.

FAQ
What is the main difference between an OBD and a hard-wired unit?
An OBD unit plugs into the diagnostic connector and moves easily between vehicles, while a hard-wired one is fitted out of sight into the wiring and is more resistant to tampering.
Which type is more secure against theft?
The hard-wired unit, because it is hidden and harder to disconnect. An OBD unit can be pulled out of the connector fairly easily.
Can I move an OBD unit between cars?
Yes, that is its main benefit. You just move it into the OBD connector of another vehicle, which suits cars that change often.
Which type does SaveTrack recommend?
It depends on the purpose. SaveTrack offers proven Teltonika units in both variants and will recommend a suitable solution based on the vehicle and your needs.
