Hi, does anyone know why my 2010 s197 front display interface module is draining the battery?
I've noticed sometimes the display lights stay on but not all the time and the battery gets drained either way? I've pulled the fuse and the battery stays charged.

Also the radio only has static which is quite loud and no music, none of the buttons work, it won't turn off and then all of a sudden it will start playing normally?

Any help will be greatly appreciated
