I would like to install 8.8" in my car, but my dealer told me not to do anything because BMW might void my warranty if i have any problem with electronics. So does anyone know if i can swap it back before service and re code it to 6.5" screen? Can they see something was coded before in some history, logs or something like that? I have my car for 9 months now so dont really want to lose my warranty...
