Hi, just looking for a little help, I have a 2014 A45. I was driving the other day and my command screen/radio flickered then went black and hasn’t come back on since, the car doesn’t play any music screen just stays black, I have tried resetting the screen, changing the fuse, I have took the screen off and opened the back no obvious signs that anything is broken, does anyone have any ideas what it could be? I have read online that it could be the chip inside the screen or could be the wiring loom, any suggestions would be great. Also, if I was to buy a second hand screen online would it just plug in and play or would it need to be programmed to my car? Thanks a lot.
