TomTom has been continually upping its navigation game, what with its partnership with Apple in iOS 6 and the HD Traffic 6.0 upgrade and requisite Android app announced this summer. Far be it from the Dutch service to rest on its mapping laurels, though: it's now poised to take on Uber and other players in the taxi-hailing world. Last week, The Next Web reported that the company acquired the taxi-fetching app maker TXXI in an effort to roll out a TomTom cab-booking service, and today the site reports that the theory is now confirmed. Speaking with TNW, TomTom said it indeed bought TXXI to "help develop tools to support the taxi market," with initial efforts focusing on Amsterdam. Last month, the company began a trial program in that city to let restaurant and hotel guests order a taxi from a mini-kiosk called the Taxi Butler. On the cab side, there's the so-called Taxi Assistant, a TomTom-branded device which alerts drivers to incoming requests. No word on whether the company will eventually introduce mobile apps, but we'd say it's a pretty safe bet.
