This modupe is DAB radio module. Problem is with TCU but if you disconnect optic fibrw cable on one but " brak3" comunication and that why you think you "fix" that.
It was a hassle to get out so I plied the correct ( brown , red/blue ) wiring and my radio worked right back up no cracks no shut offs and all controls worked.
Hi Leon- I just wanted to say a massive thank you I am from UK and had this issue, after watching your video my radio is back working full time. God bless you and thank you
Hello, do you mind describing your radio going "on and off"? Was it just the audio or was the radio screen going black and unresponsive? My screen goes black and the stereo buttons don't get it to respond. Trying to figure out if I have the same issue as you.
