I just updated to 3.0 and i have the following problems
on reboots i loose the language set by me (greek) and returns to factory defaults english
illumination turns to blue usually instead of a user custom value that i set
it opens on any source it wants with priority
1) sd card if there isn't any then
2) usb stick
and not always at the radio that i always live it
the firmware version is 3.0.20 legally bought and the avic is f 900 bt
