OK, it’s been a while since I purchased my TomTom One GPS, and I can definitely say that I like it!
I purchased the official case for it directly from TomTom to keep it safe. A little pricey at $20, but still worth it.
I also purchased a 2Gig SD card to give me some extra space. This was well worth it since TomTom recently came out with a map update. Two versions of the USA map are available on the DVD. If you have 1.4Gig spare on your card, you can opt for the more comprehensive North American Map which has a lot more POI’s compared to the standard USA & Canada map.
The new maps have shown a couple of flaws though: Roads exist on the map that don’t exist in real life. Also, one route took me on a South bound exit and told me to take a sharp left instead of taking the north exit.
