Click “Continue” to start the download and installation of the new map, then “Done” when finished. Click on 'Tools > Use Latest Map Guarantee.' If there’s a newer map than the one installed on your device and you’re within the guarantee time period, you’ll see the map update. Connect your device to your computer with the provided USB cord and sign in with your TomTom account (or create a new account). TomTom GO: If you have a TomTom GO, download and install the TomTom HOME program. It also doesn’t apply to units with Lifetime Maps since those devices get free updates anyway. The Latest Map Guarantee doesn’t apply to refurbished units or memory cards with preinstalled maps. If you purchase a unit from TomTom’s PRO series, you get a little longer – 90 days from the first time you use it. If you purchase a TomTom from the GO series, you have 30 days from the first time you use your unit to download updated maps, if available. This way, you know you’ll have the most up-to-date information when you start using your device. When you purchase most new TomTom devices, the company gives you some time to download any updates released since your unit was manufactured.
