Tape, Multimedia, Can Bus, cruise control topics

Hello friends, I did some research on a stereo system to get good sound for my 2012 LED-equipped car. Everyone recommends 9-inch Chinese-made stereos, which ensure all functions work flawlessly (for the trip computer and the remote control), but I didn't buy one because of the sound quality and the excessive cost. I had a Pioneer stereo at home. While searching for a socket to connect it, I found a Canbus and ordered one. I installed it myself and it's working flawlessly now. I had a friend who had previously installed cruise control in my car. I shared it with him and said I solved it this way. He said the car would eventually experience a BSI problem. I also researched it, and it appears to damage the brain system. Has anyone used this before and had any problems? What's special about Chinese-made stereos for cars? Does anyone know? I can share the link for those curious about the products I purchased.

Hello sir, it is difficult to break it like that. To be honest, I have never heard of it. The problem may be due to a faulty connection.
