TomTom GO Navigation is the premium mobile navigation software line from TomTom International B.V. in Amsterdam. On the current public site the same family is marketed primarily as TomTom GO Expert. Official support states that GO Navigation was rebranded to emphasise professional and truck-oriented features, while car navigation continues on the same app.
It exists as a Dutch commercial alternative to Google Maps for drivers who want downloadable offline maps, live traffic, and vehicle-profile routing. This catalog entry covers the downloadable app, not portable sat-nav hardware.
The concrete differentiator is that truck and professional vehicle profiles plus CarPlay and Android Auto on TomTom's own map stack.
