The Green Version offers specialized regional customization, distributed through local channels. This variant shines in markets like Brazil, where unique vehicle lineups require dedicated support. If you're working in regions with specific automotive requirements, the Green G3 delivers unmatched versatility.


The Blue Edition targets American market specifically, focusing on American and Japanese vehicles. While more affordable due to its streamlined features, it notably excludes motorcycle key programming – a crucial consideration for comprehensive workshops.
