Given they don't always feature a permanent Internet connection, these devices need up-to-date maps for accurate navigation. With the newest maps, GPS navigators are aware of the latest road updates, including potential closures and detours.
Needless to say, always running the latest maps is critical for the overall navigation experience. The new maps are available for TomTom GO Discover, GO Expert, GO Camper Max, and GO Exclusive, and can be downloaded right now using either a Wi-Fi connection or with a computer. TomTom has just released a new map version, bringing the database to version 1110. Compared to Google Maps and Waze, which are always connected to the Internet and always receive the latest maps nearly on the spot, GPS navigators require manual updates when the parent company releases new map versions (unless they sport a permanent Internet connection, a feature typically available on more advanced models). These devices are typically focused exclusively on the navigation experience, though they also come with one major shortcoming. GPS navigators provide route guidance to the configured destination without the need for an Internet connection, without using the phone's battery, and without any unnecessary features.
And at some level, they have every reason to be so, as navigation apps are not everybody's cup of tea.
