Check AES Wave ? I didn't really do much Mercedes or BMW programming with My MS908P and I really didn't need newer car coverage, the reason for updating it was a problem with it exiting out of Maxi Sys App and the software backup didn't work to resolve the problem. I also can't justify paying the $500 price difference between the update for a MS908P and a MS906BT if I don't program BMW and Mercedes vehicles too often, so I looked around for the best price I could find on the update , since I needed to get the tablet working again.
