BMW E91 320D 2006
iDrive stopped working after i installed a subwoofer.
I took signal wires etc. firstly to an adapter an then to the subwoofer from the default amplifier in the trunk. I used splicing sleeves. After doing this the all worked fine the first drive. The second time the iDrive did not start. The iDrive was turning on maybe half of the time i started it. When it didnt start it had flashed white sometimes. Almost like it was trying to start. I tried turning down the volume on the subwoofer and disconnecting it completetly. Nothing helped. After a while i tried cutting the wires to the adapter completly and removing all of the work i’ve done earlier. It still doesnt work. Now i dont know what to do. Its very frustrating not having the iDrive working. Can someone please help?
