I cannot speak highly enough about the virtues of the TT One, not the Audi TT one , The real TT One. Its great , ok it says you are in a field occasionally with new road layouts, but its worked well all over the uk, and across California, Arizona and other bits of the US. This summer it get to know Europe. Dont know why people want to store mp3's and pictures on them, as long as it has traffic alearts via bluetooth and your phone, thats all I need. Speed camera updates are spot on too Brilliant for the money and simple to use.
