Know this is an old post but with you about replace it since there is a good camera on board already. Always was sketchy for me also but usually if car make selected auto read and decode was more reliable 70 percent I'd say when that didn't work manually entering options did so I'm like OK take the 70 percent and then I'd know what to do if not working. Replied because in the last month it seems both not working with software/hardware (VCI) all current. Up to 25 data logs of issue but unable to send like every else even though updates can be accessed and browser online. It seems only internet failure is Autel's server for support. Ease of connection  and speed was a major pre-purchase consideration. Past month with four vehicle makes and counting failing this feature should be addressed. For now scanner is a paper-weight in drawer because speed gone from tool. Still under warranty so maybe just send it in as my time to iron out whatever their issue is they're not paying me so they can reload from scratch if they like. Currently use bar code scanner on Hunter aligner and it pretty much is flawless exception is it groups multiple years of same model if specifications the same but how hard could it be to look at the tenth place in the Vin for exact year.
