While some TomTom updates are paid, you can update your device for free with the company’s “Latest Map Guarantee” if you’ve purchased it recently or if you have a device or app that includes Lifetime Maps. Both programs are available as free downloads for Windows PCs and Macs. The company offers two different software programs to update your maps depending on what device you have: MyDrive Connect and TomTom HOME. TomTom navigation devices get regular map updates at least once a quarter to keep you in the know when it comes to route changes and new location information.
