It's not the case at all... jcv work for Taiwan, China, US maps as the apk is from Taiwan pad unit as simple as that Thailand Maps need Thailand apk and MY/SG maps need MY/SG apk that's all... Only if someone know how to modify the library or the jcv file to by pass the checking will help on these LA and JCV features or someone release their own country apk which modded from the pad... too bad these mentioned country currently don't have any street pilot app at all...
