Hi all, I am at my wits end. Had a problem with the idrive (No Nav) for a while as in mostly the menu came up as normal. Every now and then though id start the car and the menu would be slow to fire up and when it did it was a different menu which was shorter and in German. In the meantime i had to replace the cic controller which got damaged. Got a brand new one which worked fine except for the menu being faulty. I was told it now needed a software update. I got this done and the guy told me that the update worked fine but i need a new screen as it now is totally blank. What i find odd too is when i start the car the BMW logo comes on before the screen goes blank. Radio etc seem to all be working although i cannot see the screen. Help please. !!
