Never get lost again with a TomTom global positioning system (GPS) device, designed to show you your location and offer you turn-by-turn driving instructions. Updates to the TomTom software and GPS maps are periodically made available to fix bugs and update road changes. Such updates are available for free to TomTom users.
Launch the TomTom HOME software, found in your Mac's "Applications" folder or in your Windows "Start" menu. If you don't have TomTom HOME installed, download and install it for free from TomTom's official Web page.
