Welcome
With the TomTom LINK 105TM you can retrieve fuel consumption data over the OBD-II connector in
your vehicle and see this in WEBFLEET in real time. TomTom LINK 105 works together with the
TomTom LINK 5xx/4xx via Bluetooth and therefore requires minimal installation effort. This
document shows how to set up your LINK 105.

Important safety notices and warnings
Important: Read the following safety instructions carefully. Read the instructions in this document
carefully.
TomTom Telematics accept no liability for damage that results from disregarding the safety
instructions. This document is part of the product. Keep it in a safe place. If you pass the unit on to
a new user, make sure you give them this document as well.
Danger of explosion
Parts of the TomTom LINK 105 can cause sparks that can lead to explosions. This may endanger
human health and life. Do not use the unit in areas with high risk of explosion. When using a
TomTom LINK 105 in a vehicle fuelled by liquefied gas, follow the safety regulations of the country
in which the vehicle is operated.
Damage caused through improper installation
The installation and initial operation of the unit must be performed by authorised personnel only
for example, a qualified radio dealer or an automotive electronics workshop.
Risk of injury in case of accidents
Do not mount the unit or accessories in the inflation area of airbags or in the impact area for the
head or knees. Choose an installation location that will avoid interference with displays, safety
equipment and controls.
Damage to the chassis
Make sure you do not drill into parts of the chassis that have structural or security-related
functions. This is because you cannot be certain that they will function properly after modification.
Risk of fire
Make sure you do not drill into covered wiring harnesses, fuel lines or similar components. Drilling
into these can cause fire.
Repair and replacement
Repairs must be carried out by authorised and qualified personnel only. Never replace damaged
parts of the unit yourself. Send the defective unit to TomTom Telematics for repair. Only the
qualified staff of TomTom Telematics are authorised to repair or replace parts.
Damage to the device
Short-circuits inside the unit can be caused by contact with water or other liquids. The unit may be
damaged by contact with water. Use and store the unit in an area protected from water.

105 from the connector and reconnect it afterwards.
Important: To remove the LINK 105 from the OBD-II connector, pull on the handle of the LINK 105

Requirements
Before installing your LINK 105 make sure you fulfil the following requirements:
Your vehicle is fitted with a LINK 5xx/4xx with the firmware version 5.0 or higher.
The LINK 5xx/4xx must be activated in WEBFLEET.
Your vehicle has an OBD-II connector. If the OBD-II connector of your vehicle does not provide
enough space to insert the LINK 105, you can use the OBD-II extension cable from TomTom
Telematics.
To use the Activation Tool for your LINK 5xx/4xx, you need a laptop with the Activation Tool
installed, the Mini USB cable and the activation code, which you can find in your WEBFLEET
contract confirmation.

Download the latest version of the Activation Tool from the Partner Portal. Go to telemat-
ics.tomtom.com/support and select Activation and Diagnostics.

There are two steps to setting up your LINK 105:
1. Configure a Bluetooth connection between your LINK 105 and your LINK 5xx/4xx.
There are two ways to establish a Bluetooth connection between your LINK 105 and your LINK
5xx/4xx:
By configuring a Bluetooth connection with WEBFLEET
By configuring a Bluetooth connection with the Activation Tool
Make sure you have properly noted and entered the Bluetooth address of your LINK 105,
which you can find on the label on the OBD-II plug.
2. Install your LINK 105 in your vehicle.
Important: If the LINK 105 has been used in another vehicle before, you need to reset the device
before you start the engine of your vehicle, otherwise the calculation of the fuel consumption may
be incorrect.

ments for the installation.
