So after 1 year old scanner is a useless tool since upgrade is same cost as a new scanner that would work on my truck ,Autel MaxiCheck MX900 doesn’t read trucks from GMC with a Duramax, now they want 160.00 dollars just to take up space in a tool box. I don’t think so will just toss in garbage can and go on-line and inform people it’s a scam unless you owner a shop but for personal use it’s useless, will not even read fault codes once download subscription isn’t upgraded yearly
