Dont judge me guys. I had to replace battery on my 2014 A4. I didnt purchase OEM battery. So I made a mistake when connecting battery. when I connected, as you guys know, the battery posts are opposite than american batteries. Now my Radio/ MMI display not working. I've checked every fuse (in trunk and both sides inside of front vehicle). Am I going to have to purchase new display or is there another fuse behind the display/radio? please help

 

Anyone? :/
