According to my understanding, the BMW 3 Series plus bracket usually does not need to be programmed. A stand is a structure used to mount on-board equipment or accessories, such as luggage racks or bicycle racks. These brackets are usually standardized and can be mounted directly on the vehicle without special programming. However, if you are installing some advanced on-board equipment, such as a navigation system or rear-view camera, you may need to do some programming to make it compatible with the vehicle's electronics. It is recommended that you consult an authorized BMW technician or dealer for accurate information and guidance.
