Hi guys, Could anybody point me in the right direction to try any figure out what is happening with my radio. Long story short my CCC unit failed and was beyond repair. This unit was the CCC style with the CD drive and the SAT disc drive only nothing else. I came across a bundle on the internet that consisted of a CCC pretty much the same but has the buttons 1 to 9 under the CD drive, 8.8 screen and facia. I’ve installed all the parts and all my idrive comes on but there’s no sound from the speakers. I’ve had a look at the MOST fibre loop and I’m getting lights at every module ie: logic 7 and tv/video module/ logic amp has a solid orange light illuminated at the bottom. My car doesn’t have AUX or Bluetooth so do I continue to throw money at the sound system or just install a separate Bluetooth radio in where the CD changer goes and re-wire all the speakers and be done with it. Apologies for the long post but I thought I’d give all the info I could.
