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
