Hi! I recently bought a Maxidas 708, registration is successful, works well. When did the program's system update 3.30 to 4.10, the program's car stopped working. There is an inscription (The language is not authorized!), In addition to open (update) in the string (program's) name is not visible to the car, and the squares, there are some cars with English letters. Maybe the device is intended only for China? How to correct this situation? What need to buy additional programs? Well that before upgrading did a backup SD card with it and work. My email is hennvc@yahoo.pl.
Thank you.
