Improvements can be shared with other users through TomTom Home, TomTom's content management software. An online version called Map Share Reporter is on the TomTom website. IQ Routes, developed by TomTom and available since spring 2008 on the TomTom Go 730 and Go 930, uses anonymous travel time data accumulated by users of TomTom satnav devices. Newer TomTom devices use this data to take into account the time and day when determining the fastest route. Travel time data is stored in Historical Speed Profiles, one for each road segment, covering large motorways, main roads and also small local roads. Historic Speed Profiles are part of the digital map and are updated with every new map release. They give insight into real-world traffic patterns. This is a fact-based routing system based on measured travel times, compared to most other methods which use speed limits or ‘assumed’ speeds. In September 2008, map upgrade v8.10 was released for x20 series models, extending the IQ Routes feature to those devices with a free software update using TomTom Home. On the NAV3 and NAV4 models the IQ Routes feature is available by default on all map versions. Mapping TomTom worked with auto parts manufacturer Bosch, starting in 2015, to develop maps for use in self-driving vehicles. Bosch defined the specifications for TomTom maps to follow as they began first road-tests on U.S. highway I-280 and Germany's A81. TomTom commented at the time on the contrast in details required in those newly developed maps compared with earlier versions, specifically including "precision to the decimeter" and other complex data required to help a self-driving car "see" key road features as it travels. In 2015, TomTom was one of the only independent producers of digital maps that remained in the marketplace as they partnered with brands like Volkswagen to provide maps in the auto industry. The company also partnered with Uber in 2015, and extended the partnership further in 2020. Together the companies have worked to integrate TomTom maps and traffic data across the ridesharing app's platform. This lets Uber serve as a "trusted map editing partner", making it one of the first brands to join TomTom's Map Editing Partnership (MEP) program. As part of the MEP program, users provide feedback on road conditions as they encounter them so that live maps can be updated to reflect current conditions. The program estimates 3 million edits monthly by its
