What is the Geotab Truck Solution?

The Geotab European Truck Solution provides the opportunity to serve a wide range of fleet needs with ease and efficiency across Customer segments. This is a flexible custom package that offers solutions and benefits when used with the Geotab GO device, and allows Customers to access data in one compact location: MyGeotab. The principal component of the package is the Geotab Tachograph solution, composed of a dedicated Add-In ("RDL" for Remote Download, "TAC" for Real Time Information and "AFA" for Infringement Analysis) and other features available in MyGeotab (Driver ID, Driver Status etc.). The Geotab Truck Solution also has a contactless connection to the CAN Bus line of the vehicle to read engine data if the vehicle’s OBDII connection provides only limited data, or if the FMS-Standard port is not enabled.

What kind of data does the Geotab Tachograph provide?

The solution includes some real-time information available in MyGeotab, and an Add-In which includes three modules:

  1. RDL, the tachograph download, compliant with legal requirements from the EU;
  2. TAC, the driving and rest time for real-time status information and its corresponding report; and
  3. AFA, an analysis-based infraction detection tool to identify potential infringements in the tachograph files.

The Remote Downloading System (RDL module) for tachographs in the European market provides automatic remote downloading of all information, updated in real time, and eliminates the need for manual management of driver and vehicle information. This module also allows you to set email alerts for expiring company or driver cards, expiring legal downloading periods and more.

Real-time driver status (TAC module) is a dedicated report for driving and rest activities, in compliance with European requirements. All real-time data can be organized in reports for daily, weekly and bi-weekly periods, and can be used to examine markers such as effective work, country of origin or kilometers per day. This information provides an easy and effective way to manage drivers and vehicle planning.

The Infraction Analysis module (AFA module) provides access to a deep analysis of infringement detection, such as driving time infringements and incorrect manual entries. This feature provides full compliance with European requirements.

The Geotab Tachograph is designed to comply with all European data regulations and requirements.

How does the Geotab Tachograph work? What is included in the hardware?

The Geotab Tachograph works using a combination of products: the GO device (GO9 or later), IOX-UREADER and Tachograph Connection Harness (HRN-URTACHO).

The hardware is composed of:

  1. IOX-UREADER (hardware gateway); and
  2. HRN-URTACHO, a dedicated harness for connection to the rear of the tachograph.

In the vehicle, the IOX-UREADER is connected to both the GO Device and to the digital tachograph. This allows the GO device to read data and send it to MyGeotab.

For automatic download of driver and vehicle information, the company card must be inserted into the card reader. Information is downloaded periodically and automatically, in compliance with Regulation EC 3821-85 (M16) dated 10 June 2013.

Is the product warranty the same as that of the GO device?

No. The warranty for Geotab Tachograph products follows the conditions in your Rate Plan or specific Partner agreement.

Is a professional installation required?

Yes. You are required to use certified installers or workshops to avoid issues when installing your devices. Professional installation provides sufficient technical knowledge and expertise for mobile device installation and integration in modern vehicles.

Can all digital tachographs be adapted to digitally download the information?

No. There are certain restrictions according to the manufacturer:

  1. Stoneridge: All models after and including version 7.
  2. Siemens/VDO: All models after and including version 1.3.
  3. Actia: All models that include the word "Remote" or have a reference number greater than or equal to 921872.
  4. EFAS: All models since model EFAS-4 with version 2.00–2.15 and higher.

If you are still unsure, you can check the Compatibility Check Tool or reach out to your Geotab contact.

Can analog tachograph data be downloaded remotely?

No. The analogical tachograph data is recorded in a paper chart and is therefore unable to be shared remotely.

Once I've installed Geotab tachograph hardware and software, is there anything else I must do to begin automatic downloading?

No. Simply ensure that your company card is connected to the card reader, and that the computer you are using for information verification is not turned off at any time. Downloading will begin automatically.

Once I've installed Geotab tachograph hardware and software, can I still download information manually?


Can the digital tachograph data be downloaded manually or remotely without the company card?

No. The company card must always be inserted in the card reader for authentication purposes. The company card needs to be inserted in the card reader linked to the DTCO-RCS software.

Can I download information from the digital tachograph remotely, even when the vehicle is several thousand kilometers away from the office or where the connected business card is located?

Yes. Our new, innovative equipment allows remote downloading of tachographs anywhere in Europe.

Who is responsible for the information contained in the digital tachograph?

Tachograph information is the responsibility of the company or person holding or leasing the vehicle. The tachograph retains the information on vehicle and driver cards for 365 days. This information is also stored on our cloud servers, eliminating the risk of data loss due to accident or damage.

Before an inspection, what files do I have to deliver?

According to the current regulations, you must provide all vehicle files indicated in the inspection, as well as all driver files with activity in any of the vehicles during the indicated period. Use the Inspections view to calculate the minimum required files.

Can I view all the driver’s vehicle information?

Yes. This information can be found on our platform.

How much is the average data consumption (Mb/month) per vehicle, requiring remote download?

The Geotab Tachograph requires around 5Mb/month per vehicle to transfer tachograph and driver files, depending on the frequency of the download.

What are the limitations of the system?

There are no technical limitations of the system. For example, if a company with a fleet of vehicles with tachograph needs to download data every day for its vehicles or drivers, the system can accommodate one or more company cards connected to help increase the frequency of downloads at the cost of consuming much more data. For any other information, please reach out to your Geotab contact.

Can blocks be activated/deactivated in the M-file? Is it possible to download detailed speed profiles?

All blocks, called TREPs, are downloaded and it is not possible to deactivate any of them. Detailed speed (TREP4) is available in all downloaded tachograph files. There are five types of TREP available in the tachograph files:

  1. Overview (TREP 1): Includes data such as vehicle ID, last VU download and by which type of card.
