Hello folks so i just my first Audi and i love it yeah its used but i was looking to pay cash and this was one of few that had no accidents reported . So the issue i have is that the GPS screen dose not come one . radio works and i found that i could do a hard rest holding down the the right combo of buttons. But no pic on the screen

I have a 2007 Audi A4 2.0T AWD . i am wondering if the screen is just dead or do i need load any software or something any trouble shooting tips would be awesome
