So my friends 2015 audi a3 premium plus has been having stereo issues and it is not working at all now. They were told the cannot put an after market one in by audi and they cannot find anybody local who can install one. Is there anybody in the vegas area (hendersom specific) that has experience with these steroe systems and could possibly get it remedied for them or knows of anyone. Any help would be greatly appreciated.
