Tomtom is offering 3 years free maps and 2 years HD (normally only 1year) live traffic on the "live" series gps. big saving considering maps cost $99 for 1 year of maps and HD traffic cost $69
If you want to see how HD live traffic works…

ps HD live traffic works great in sydney, makes driving in peak hour a breeze. lol and will only get better with the higher uptake to the "live" gps'.
Not sure if the battery will last 3 years though (by that I mean reasonable level of battery power, not one that holds for only 30 minutes).
