I have a serious problem with the radio Kenwood DNX 9240 (eu version).
I wanted to upgrade to a newer soft from Kenwood to v 1.9 update but does not pass in full (several times hangs need to do a reset and somehow reaches the end) unfortunately disappeared bluetooth, it is basically no assets but the service program sees Parrot module also even no contact with him but he Kenwood that is no longer displayed.
Besides disappeared somewhere all available languages GUI - rumored to be available any software to restore poorly currently loaded firmware -

for all the help I would be very grateful - I greet Michael
