The map itself is more km, more roads ..... like any Melways, Sydways, BrisWays (do they have one ...) ... updates - The software to run it is another story that why Toyota has 2 vendors for one DVD map - The map is not big (not xxGb thing - Garmin users can download V14 very quick and they have 1 year upgrade plan too). The software is where they make money, and you can not copy software (the DVD), it simply won't run. BH I am still annoyed that as I only bought the car two weeks ago they did not giv eme the new software alan You didn't mention whether you had already asked them for an upgrade disk but, if they have declined to give you a free upgrade, I would not be letting them off that lightly. Toyota has known about the upgrade for several months and several dealerships have been selling them for the last couple of weeks so there is no question about their availability.
