hi, i hope someone can help with this problem. i have a 2001 4.4 x5 and the sound from the audio system doesn't work. everything else works. cd changer, satnav, radio & steering wheel controls, just no sound. i have checked the amp by plugging in a house speaker into the plug connector nearest the camera and sound is coming out. i assume that this is the feed from the head unit. i plugged the speaker into the other 2 connectors but nothing coming out of these. is there any other way to check it, or is it broke?
i also tried to remove it by removing the 4 screws around the top, but it would not come out. where are the other bolts holding it in?
sorry about the quality of the picture.
any advice welcome. thanks
