The night time illumination on my Mk3 factory stereo is very erratic, I suspect a bad connection. But before I can begin to find the cause I need to get the damm thing out. I've had a good look all around it and can find no obvious screws, clips or tabs to release to remove the unit. The last thing I want is to damage the facia by incorrectly prising it out. ........... Can anyone help !!
