Hi,

I installed a new screen in my 2011 e92. Now experiencing the following issues;

-Aux volume cannot be turned up
-USB port in arm rest doesn't work
-bluetooth doesnt appear to working as i cannot pair phones now.

Initially i wasnt getting and signal to the screen as the radio (#14) had blown replaced that and screen was working fine.

Is there a fuse that maybe blew that is causing these issues? Tried to figure that out from the fuse box diagram but nothing appears to represent that.

Thanks

F13 goes to eject box which powers combox which control all the things listed.

Thanks I did check that fuse and it seems fine.

Looks like there is two fuses to combox.. Other is f59

Thanks

I did check that one as well it it seems to be fine. Replaced it a new fuse just to be on the safe side.

You can check to make sure power is getting to combox in trunk. Its plug x34130 pins 1 and 2 for positive voltage and 14 for ground.

By screen to you mean an OEM BMW Screen or one of those cheap Android Screens?
People who change to an Android Screen get this problem when they don't transfer
the Fiberoptic to the new harness and also when the don't realize the aux and usb come
from the combox in the Trunk.
I would start out by checking the radio connections.

I don't know if programming effects the screen but that could be a possibility .
You should check in the idrive sub forum.

Yes it is one of the units.

It was actually working but as i was finishing the install my battery run down and i blew the radio fuse. This got the screen back. I checked all the other fuses and they were fine. So just trying to diagnose. I will check the combox thanks for the suggestion.
