Hi, first time on any forum. I want to upgrade my entire sound system. In order to do this do I just simply unplug and remove everything in the trunk and then run all new wiring from my new head unit? Sorry if this is a dumb question but I don't fully understand how all of the sound system electonics function with the rest of the car.
It’s never as simple as plug and play in a bimmer. Here are the wiring diagrams: https://bmwteka.com/wds/en/e38old
Thank you for the wiring diagrams, but can I not just bypass all of the original system?
That would require ripping out a lot modules and wiring. The audio system, even in that chassis, was fairly integrated.
