I can gladly say that the current OS update went smoothly albeit SLOWLY - as in many hours (incl. vehicle updates). Also this OS update did not erase off the current vehicles but left everything intact showing all available updates. Very satisfied so far with my 905 mini. I never expected it to have extensive programming capabilities, however the live MAF data has never been correct on any vehicle no matter what OS I've been on. Seems to be an Autel problem. I have to use my cheap scanner just to monitor MAF live data.
