If it still has the car company logos figure 2013 -2014. Multi colored round buttons with car brand names, some brands had 2015 coverage but some listed special functions might be missing or no longer work due to gradually  dumbing things down after the MaxiSysPro became the Flagship and after  Ford Lawsuit. If it works as is , I would strongly advise not to let connect it to WIFI and try and connect to Autel server.

 Make a backup of the SD card too.
