Hi
I took out the android screen and the AC touch screen to do some repairs and when I connect everything back , the AC didn't even switch on totally dead , then I put on the old one without the can bus and again nothing all black.
Also at the same time my backup camera not working because the reverse lights don't work.
Any ideas please?

This car really hates the battery being below like 9-10 volts so before doing ANY thing else, I would recommend to atleast verify your battery is completely fully charged.

I just installed the aucar and ac unit only a few days ago and had a similar issue where just opening the door and closing the door as I was spending a few hours taking apart the dashboard and etc was enough to cause the battery to lose those few volts and then all the same strange issues started happening to me, like the headlight stopped working etc. as soon as i fully charged the battery and put it back in the next day everything worked immediately with no errors on the dash and etc.

Hi , and thanks for the reply , it was the first thing I have done to fully recharge the battery but again the same , maybe you know the fuse for the AC unit? Or what? I am running out of ideas.

I have taken my AU car unit out/in several times, adding options, and a similar occurrence happened to me. What I found was that all the movement loosened some of the plugs in both units and they were not connected properly. I used some die electric silicone ensured the plugs were tight and everything came back on. If you have a first gen AC touch screen then you need the old unit to reset. Robin has a video on this available on this site.

Yea this is a good idea as well, since both of the units now dont work it could also be that a Pin is loose on the connector, I could easily see that happening as theres barely any room to actually plug in all the wires back there so its easy to see how stretched they get.

I found the problem.
Fuse F49 was bad and I found out because no buttons worked on the steering wheel and looked for this fuse , when I changed it the AC screen worked and the reverse light also , this fuse is responsible for a lot of things.
