Product Description:
All the newest TeleAtlas maps are installed on an SD card as one seamless map - allowing you to find your way to any address in the USA or Canada.

Rating : - Expensive, but (mostly) worth it
I bought this for my brother-in-law, who had purchased his TomTom while living in Europe. He wanted the North American maps after he moved back to the States. While these maps cost roughly two-thirds what a new device would, they're thorough and well-presented. If you've got a compatible TomTom system, go for it!
