TomTom provides you with the latest map pre-installed on your new device. In the event that a newer map is available within 30 days from when you start using your device, you are entitled to one free map download.
So if you download a map and a newer one comes out, like 8.15 did in my first 30 days, you are SOL. My advice would be to hold off using that guarantee till you are close to the 30 day mark. Personally I feel that a "Latest map guarantee" should included all updates within the first 30 days or it truly isn't a valid guarantee. Lesson learned. Hopefully others will benefit from my mistake.
