No Radio sound AM/FM

When I got my 2015 GLA45 I had no sound on any input except the sat(sirius)

I checked everything (fuse/optical loop...) and plugged it back and it Worked for a bit and went off again when I put back in the unit completely. So my first guess was a lose wiring but all seems good on this side.

I checked the diagnostic and got 2 error on the ground of the antenna. If anyone knows where to check or troubleshoot those ground. I checked in the rear and cannot find them. Is it part of the windshield since it has been changed recently?

Do you have an aftermarket screen? It may be possible that is causing the issue. I wouldn't be surprised if the wiring or a connector in the aftermarket is faulty. did you have this issue before replacing the screen?
Yes I had this before the replacement and it was working briefly even after the replacement for the first time.
From the diagram I can see there is a splitter some where, I think It's coming from that sincd the sound was cutting while I was moving the Headunit. Otherwise It's the Headunit itself but it looks good from what I see.
