Perhaps, but that's still a little different than selling a kit that replaces the factory equipment to replace the app and would depend on how exactly it was accomplished, after all those infotainment systems have license agreements, while I may be allowed to modify the software for my own head unit, providing it to others probably isn't allowed, especially if I'm making a profit. So while it's the kind of thing that should be legal, I'm guessing if anyone started selling kits to replace the dealer app with a third party one they'd be going to court.
