Talk about BMW's little secret

BMW is simpler than Audi and Mercedes-Benz.

     1.BMW EVO and MUG are relatively complicated, especially the models with touch screen. The touch data of the original car screen and the main unit produced in different places are different. This is a big trouble for the aftermarket and the development cost is high. , it is difficult to be compatible with each other. The difficulty lies in the need to buy a lot of original car screens and mainframes to debug, but the new car screens and mainframes are relatively scarce, and the selling price is also very high. It costs about 20,000 to 40,000 yuan to buy a set.

     2. Next is the CCC system, which is a bit harder to do than CIC and NBT. Because the vehicle is relatively old, the original car chip and canbus communication information are    relatively backward, so the compatibility requirements of post-installed products are relatively high, so as to prevent damage to the original factory's fragile chip and avoid the canbus system reporting errors.

     3. CIC and NBT are relatively simple, but they also need to be compatible with the protocol and video signal of the original car system, so the hardware design requires rich experience and more energy to change. It takes more time to accumulate and feedback from customers during installation to improve and improve the hardware or software in order to be better compatible with the original car system.
