A quick check of the Sygic website shows that they have now opened an e-shop to sell Sygic Mobile Maps for Android, Windows Mobile and Symbian direct. Currently they support Complete Europe, Australia & New Zealand and US, Canada & Mexico so there is no smaller regional versions. Prices are currently (14th Sept 2009) as follows
    Central Europe - €79.99
    Australia & New Zealand - €59.99
    US, Canada & Mexico - €62.99
Payments are handled by RBS Worldpay so it is probably possible to pay in £GBP or other supported currencies (from my experience with Worldpay and $US transactions).
The advertised version is Mobile Maps 9 but the internal build is 7.71 - the same as McGuider 2009 and Mobile Maps 2009 so I suspect (no proof though) that MM9 is the new name for the 2009 version.
