Nokia Navigation :: Loading Country Map Into E72?

Can somebody advise me how to load a map of Thailand into the E72 phone? When connecting to the Nokia Suite, map of Thailand is not available. But the other phone Nokia 500 could find the map on web and through "actualisation" and "add map" icons the map of Thailand could be downloaded. But the E72 does not offer the possibility of loading the map directly from net (could not find any icon "add map"). According to manual, E72 offers only loading the maps through the Nokia Suite (but this does not contain the Thailand map). To solve the problem means - how to force the phone E72 to be able to download the maps from net. Where is the problem - phone itself (should I upgrade the system) or the application Maps (should I upgrade the application Maps)? Seems to me unbelievable that (when the map actually exists) I could not get it into E72 phone.
