We have put together a short list of frequently asked questions. Contact us for further questions.

How do I connect the onTrak device to my phone / tablet?

The device connects over Bluetooth so no annoying wires! When the device is on and the onTrak application is open the Bluetooth will connect automatically.

Will I need a data connection on my phone / tablet?

No – If there is an Internet connection available the onTrak app will use AssistNow to download satellite information data for the quickest GPS fix in the industry. Otherwise the onTrak app only requires an Internet connection to install periodic updates.

How accurate is the onTrak Device?

The onTrak Pass-to-Pass accuracy is industry standard 20-30cm. The onTrak device contains a high quality GPS module, which takes advantage of all the freely available correction systems available including, EGNOS, WASS and GLONAS.

What if my machine doesn’t have a metal bonnet?

We supply two sets of special mounting disks. These 3M sticky backed disks are made of magnetic material which forms a very strong connection with the magnets on the onTrak device. Most modern tractors have a metal area somewhere on the bonnet.

Is the onTrak Device waterproof?

Yes, as long as the USB cover is in place, the onTrak device is completely water and dust proof.

Should the GPS receiver not be on the roof?

Our testing shows that there is no negative effect of placing the receiver on the bonnet instead of the roof. In fact mounting nearer to the front wheels actually makes the guidance more responsive.

Can I charge the onTrak device while in use?

With 24 hour battery life it’s unlikely you will need to charge in use. If for some reason you run out of juice you can charge the device while in use. Please remember that the device is not waterproof with the USB cover removed.
