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.
Connect your TomTom device to your computer. Connection methods vary by device. Typically, use your device's included syncing cable attached to an open USB port on your computer. If you are unsure, consult your device's user manual.
Press the grey "Update my device" icon at the top of the TomTom HOME software screen. The software will connect with TomTom's online server to see if your device's software and maps need an update. A list of any applicable updates will be displayed.
Click "Update and Install." The software will automatically download and install the updates to your TomTom device. Wait for the TomTom HOME software to complete the installation process before proceeding.
Disconnect your device. Click "Devices" in the top of the TomTom HOME screen and select "Disconnect Device" from the drop-down menu. Unplug the device from its syncing cable and resume use.
Your computer must be connected to the Internet to check for updates and download new TomTom software upgrades.
