[19] TomTom signed deals to provide their navigation devices to several carmakers including Volkswagen Group, Daimler, Toyota and others.

[45] A company press release in June 2023 announced that support for sports watches and other wearable products will be discontinued from September 2023.

[49] Location technology comprises the company's automotive and enterprise businesses, providing maps and navigation software as components of customer applications.

[50][51] TomTom's enterprise segment sells its location technologies to tech companies[clarification needed], government bodies, and traffic management entities.

[50] The consumer segment of TomTom's business sells portable, personal satellite navigation devices,[50] once its core profit center.

Usage of standalone GPS devices has since declined,[52] despite the brand's efforts to contrast features to those of smartphone integrated alternatives.

[53] Recently, the company has transitioned its consumer business away from devices to offer software applications instead with digital maplinked services.

[50][54] This shift in focus is due partially to declining profitability as consumers utilize GPS alternatives with integrated navigation apps, and also to the anticipated rise in autonomous vehicle usage.

[52] TomTom as a company offers three types of products in different shapes and forms: maps, connected services and (navigation) software.

They use a GPS receiver to show the precise location and provide visual and spoken directions on how to drive to the specified destination.

Some TomTom systems also integrate with mobile phones using Bluetooth, traffic congestion maps or to actually take calls and read SMS messages aloud.

TomTom's all-in-one GPS navigation devices come with a touch screen, speaker, USB port, internal Lithium ion battery.

With version 2.2, TomTom Home added a content-sharing platform where users can download and upload content to personalize their device such as voices, start-up images, POI sets, etc.

By mid-2011, TomTom Live services including TomTom Traffic were available in the United States, South Africa, New Zealand and seventeen European countries: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Luxembourg, Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

On the x0/x00/x000 devices the traffic service is free of charge either via the built-in SIM (Always Connected models) or via a compatible smartphone (smartphone-connected or BYOD – bring-your-own-device).

In September 2008, map upgrade v8.10 was released for x20 series models, extending the IQ Routes feature to those devices[70] with a free software update using TomTom Home.

TomTom worked with auto parts manufacturer Bosch, starting in 2015,[72] to develop maps for use in self-driving vehicles.

[82] TomTom has also been developing High Definition (HD) maps intended for use in autonomous cars to assist with environmental data where sensors are limited.

[83] The company announced in March 2019 that they would supply HD maps to "multiple top 10" auto manufacturers that would provide centimeter accuracy in representing terrain; and announced a new "map horizon" feature, allowing self-driving cars to simulate a virtual picture of the road ahead in real-time.

[79] The company partnered with Volvo the same year (2019) to build its own vehicle capable of "level 5" autonomy in hopes of further improving its maps technology.

The Volvo XC90 included custom sensing equipment to provide data about the vehicle's surroundings that could be referenced against TomTom's HD maps.

[82] In April 2011, TomTom "apologized for supplying driving data collected from customers to police to use in catching speeding motorists".

[91][92] In May 2011, the company announced that it was planning to sell aggregated customer information to the Roads & Traffic Authority of the Australian state of New South Wales, which could also potentially be used for targeted speed enforcement.

[93] The privacy implications of this announcement were widely reported, particularly the lack of anonymity and the potential to associate the data with individuals.

David Vaile of the University of New South Wales' Cyberspace Law and Policy Centre has called for an independent technical analysis of the company's data collection practices.

In addition to this, he said TomTom never sold the information to Dutch authorities with speed cameras in mind, although Kearney would not rule out selling the user data for similar use in Australia.

[95] It is not known if governments use this data for purposes other than the placement of speed cameras, such as to improve the road network, introduce traffic lights or find accident hotspots.

In November 2023, a woman was "following audio directions" when she drove down the slip road near the Little Brickhill junction, resulting in two deaths.

In a Prevention of Future Deaths report, the coroner noted police attending the crash saw three other vehicles "perform exactly the same manoeuvre and attempt to travel down the slip road in the wrong direction".

[104] TomTom's main autonomous driving HD maps competitor is Here, which is owned by a consortium of German automotive companies including Audi, BMW, and Daimler.
