Hello. I am looking to replace my Infotainment unit in my 2016 Mazda 6. The actual install looks fairly easy. But I've seen a few mentions about how only the dealership can "unlock" a unit, or that the anti-theft will brick the car, etc...Anyone have more info on this or can point me in the right direction. Also, if anyone has replaced the touchscreen part only. really the unit is fine but the touchscreen has tiny crack and is separating now. So replacing the touchscreen portion only is an option too. Thanks for any help.
