When you can fit a GPS tracker yourself and when you need a technician: installation steps, timing, common mistakes and a test checklist.
GPS tracker installation means connecting the tracker to the vehicle's power and ignition and, if needed, to fuel level sensors and the CAN bus. This is a job for a technician: a wiring mistake gives you false data and sometimes a flat battery. A cigarette-lighter or OBD tracker, on the other hand, you can plug in yourself in minutes.
Below we explain when you need an installer, what the job includes, how long it takes and how to check the result.
When you need professional GPS tracker installation
Call a technician if the tracker has to be wired into the vehicle's electrics or other systems. For example, when:
- the tracker must run reliably on vehicle power and detect ignition;
- you need a fuel level sensor with tank calibration;
- you want CAN bus data: mileage, fuel consumption and fuel level from the on-board computer;
- you plan remote engine immobilisation via a relay;
- it is a 24 V truck, a tractor or construction machinery;
- the tracker has to be hidden so a thief won't find it.
What a GPS system installation includes
- Inspection and choosing the spot. The technician finds a place with good satellite and mobile reception, protected from moisture and out of the driver's way.
- Power connection. The tracker goes to a permanent positive feed through its own fuse, so a short circuit can't damage the factory wiring.
- Ignition and inputs. This lets the system count trips, stops and engine hours correctly.
- Sensors and CAN. If the project includes them, they are fitted and connected at this stage.
- Configuration. The tracker is added to Navi.zone or Wialon, with data intervals and alerts set up. More on our GPS tracker setup page.
- Testing and hand-over. The technician shows the tracker on the map, checks ignition and sensors and records where the tracker is mounted.
How long does installation take?
It depends on the vehicle, access to the wiring and the number of sensors. Typical timings:
| Hardware | Who installs | Typical time |
|---|---|---|
| Cigarette-lighter or OBD tracker | You | A few minutes |
| Basic tracker (power + ignition) | Technician | Usually 1–2 hours |
| Tracker + CAN bus reader | Technician | Usually 2–3 hours |
| Tracker + calibrated fuel level sensor | Technician | Half a day or more, depending on the tank |
Common DIY installation mistakes
- No fuse on the power line.A short circuit can damage the factory wiring.
- Switched instead of permanent power.The tracker turns off with the ignition and can't see what happens while the vehicle is parked.
- Tracker under metal.The GPS signal weakens and the track jumps or drops out.
- Tracker not secured.It rattles around, and the contacts loosen over time.
- Uninsulated twisted wires.They oxidise within months and cause faults.
- SIM card with a PIN code.The tracker never connects, even though the wiring is fine.
How to test a GPS tracker after installation
- The vehicle appears on the map where it actually is.
- Switch the ignition on and off — the dashboard should show it.
- Drive for 10–15 minutes: the track should be continuous, without gaps or jumps.
- If there are sensors, the readings make sense: the fuel level doesn't jump while parked.
- You know where the tracker is and have a photo or note of its location.
GPS tracking without installation
Not every task needs a wired install. If you just want to see a car or van on the map and get trip history, a plug-in GPS tracker will do. Plug it into the cigarette lighter or OBD port and it works.
The limits: it is easy to find and pull out, it can't read fuel sensors and it can't immobilise the engine. For theft protection and fuel control, a hard-wired tracker is the better choice.

FAQ
Will installing a tracker void my new car's warranty?
Usually not, as long as the connection is neat and the factory wiring is not damaged. Warranty terms differ between dealers, though, so it is worth checking in advance. The safest options for a car under warranty are an OBD tracker or a contactless CAN bus reader that doesn't cut into any wires.
Will the tracker drain the battery?
Not if it is connected correctly. A tracker draws very little current and switches to sleep mode when the vehicle is parked. The risk appears only if the vehicle stands for weeks or the battery is already old. In that case you increase the parked reporting interval or enable deep sleep in the settings.
Can the tracker be installed covertly?
Yes, if it is your own vehicle or your company's. The technician will pick a spot where the tracker is hard to find but still gets a stable signal. Fitting a tracker to someone else's vehicle without the owner's consent, or using it to follow a person, is illegal in Ukraine.
What should I prepare before installation?
Bring the vehicle with a charged battery, the keys and any documents needed for access to control units. Decide in advance what you want to monitor: location only, fuel or CAN data. That determines the hardware, the time the job takes and the tracking plan you will need.
