The TomTom GPS device is pre-loaded with maps. Those units purchased in U.S. are preloaded with a map of the entire country, plus Canada. These maps aren't all-encompassing and may be missing information that you want, such as business-specific map coordinates. Google maps are formatted in KMZ, which is not compatible with TomTom GPS devices. However, Google Maps and the TomTom HOME software, which manages content to TomTom devices, will convert KMZ-formatted Google maps so they can be used on your GPS.
Download the TomTom HOME installation file online (see Resources). Select the option to save the download file to your computer, and then double-click the installation file "TomTomHOME2winlatest (1).exe." Allow the file to install on your computer.
Connect your TomTom to the computer using its USB cable. TomTom HOME should automatically launch. If it doesn't, select "TomTom HOME" from the desktop "Start" menu's "All Programs" folder.
Go to Google Maps (see Resources).
Select your Google map. Enter a city and state into the search field, and then hit "Search Maps." You can also select "Businesses" from the search option drop-down menu, and type "what" and "where" (such as "dry cleaner" in "New York City") in the corresponding search field. Click "Search Maps."
Click the "Send" option at the top-right of the map once you find a business or location.
Select the "GPS" tab in the "Send to" window.
Select "TomTom" in the "Brand" menu.
Select the address that you want to transfer to the TomTom in the "Include" drop-down menu, and then press the "Send" button. This will send a signal to your TomTom HOME software.
Select one of the following options in TomTom HOME when prompted: "Show on Map," "Navigate to it" or "Add to favourites." The KMZ map is then downloaded to your TomTom GPS device.
