    Hi everyone - Renault Master 2005 radio flashed without a problem, in winter frost at strict night AL and the battery froze, the radio decoded, I entered the code. From under the steering wheel (3356) and the circus - when the radio is switched on, the radio is off, a separate dark display, the switch under the steering wheel does not work, off and czam radio and after a while, the display dark - switched off under the steering wheel does not work, I can change stations on the radio, adjust the voice, and the dark display - the radio turned off - after switching on, the display goes silent and the Christmas tree appears on the display. I disconnected the battery (2 hours) and did not let me into the code mode anymore. Only the Christmas tree is lit, that is all the time, it only reacts to the lights switched on, changing the picture to a poorer one, on and I have two photos. I read the internet a bit and did not come across instructions that would help me.
    Maybe one of your colleagues knows the step by step procedure with this "machine" ? ??
