2005 Audi A4 B7 MMI Question
 

Hi new to the forum, I own a UK model, 2005 audi a4 b7 3.2 that has a MMI including sat nav, everything has been ok until recently the screen went blank, I can hear the radio is on so could it be a screen issue? . I've seen ways to reset the modern versions of these but can not find any way to soft reset this. I've disconnected the black wire from the main battery but that hasn't made the slightest difference :-( Any ideas?

I came across this article
