hello everyone, I am working on this and might need some help, I have The screen, CMU, Controller Knob and usb port with all it harness connected and I'm using a 12 v 3Amps power supply, but it doesn't turn on, just the fan for a few seconds, do I need the Body Control Module to make this work out of the car?

The CMU and Screen need ACC and B+ to powering on. Did you connect both wire to them?

Yes

Hi

I try to do this too. I have full wiring diagram for Mazda connect. For all modules there is ground, b+ and something called "PWR CTRL OUT". It's a connection between control board, display and USB hub. I can't power it all too, I'll try to power it with can message idk if this would help

please let me know, I had not luck with it and is sad because I have all parts in my room and is upsetting not having ideas to make this work.
