If its showing as 3.20 Version than don't even bother installing it you are better of with your old version.....................Stay with your old version for now till you see another update come out.....................
Opel/Vauxhall v3.20 is out there. Any one tested this new version? What are the results? Still buggy or did Autel fix the missing features and mentioned issues? Waiting for your feedback. Thanks.
