iDrive screen blank and red lines after Android install

[chrisymarr]

Wonder if anybody has seen this issue before.

I decided to install an Android screen in my E61 today.

The car is a 2007 with a CHAMP basic head unit with the smaller screen.

As I hooked up the new screen I was unable to view the existing iDrive.

I then proceeded to reinstall the original screen now the screen is black with red lines running through it although the head unit it self is working with audio working as expected

Is there a way to rectify this or is it new head unit time?
