Hi, I'm hoping that someone here will be able to assist me. I installed an Android head into my CCC fitted E60 a couple of years ago but recently it just stopped working. All of the BMW screens and functions (radio, navigation, settings etc) are still working perfectly but the only non-standard screen I can get is a black screen with 'No signal' in the center. I have tried re-setting and disconnecting but always the same. Anyone got any ideas as to whether this is recoverable? Thanking you all in advance.
