I bought the Autel MX808BT PRO a year ago so this is my review. Short review is this scanner has been worked for extensive problems on 2012 Impala without a hiccup. Used it on Caravan and Saturn Ion as well as several Nissians. Love bidirectional. Now the cons. Tool will not work without subscription on my Caravan. Caravan is not on list for buying FCA subscription as it doesn't have gateway. I checked with my old thinkscan and I can read codes as well as live data with internet connection needed to be sent to Thinkscan. Thinkscan is limited in bidirectional and doesn't work on Caravan as it states not compatible. Now should i spend money on another scanner that would be in 500 to 700 range with 2 year update or pay 150 a year and use this one until it quits.
