Hello, My friend just purchased a 2007 4.8 E70 and for some reason he cannot see ANYTHING pop up on the navigation screen and the radio doesn't work at all what so ever.

I tested every single fuse under the passenger glove box panel and in the rear right hand side as well.

Every single fuse seems to be working yet I still have no radio and nothing on the screen, any ideas? I was thinking its the HiFi amp but if it is the amp then why cant I see ANYTHING on the screen?
