Hello all, I’m working on a project at home.I have a really nice DVD player out of an suv, I have it all hooked up in my shop outside of the vehicle and it won’t power up. It has power and ground everything is hooked up just as it was in the auto. But it won’t play or light up the screen, it will load/eject dvd’s. The only hookup I cannot reproduce it the can bus + and - I believe this is a 5v communication line that all the modules in the vehicle “talk” on all at the same time of course and at different frequencies, also of course. I’m assuming that it needs this input to power up. I’m wondering if any of you fine people know a way around this or a way to replicate it and would be nice enough to share the information with me? Thank you in advance for any help you can offer.
