There are a few of us on the board that own this scanner: If you look at the U581 model, it's physically identical to the U381. Apollo rw 2009 sterowniki. U581: Well, the U381/U581 aren't just physically identical, they're the exact same hardware inside just with different software.
The U581 supports everything the U381 does plus it has CAN support. The hacker in me tried updating my U381 with the latest U581 software. The update software picked up the scanner right away and flashed the firmware without issue. Happy negative marriage raw. I haven't yet scanned a CAN equipped vehicle, but regular OBDII scanning works just as before. Esf databases. Live data, monitor information and every other function of the OBDII U581 software works just fine on my U381 labeled unit. If anyone else is feeling adventurous, here's the link to the U581 software update: It includes the updating software so that's all you'll need to download.:) Picture of my U381 with the U581 software: http://imgur.com/Bkrjq.jpg.
