The McIntosh head unit in my 2011 GT started to play up more than 9 months ago. It stopped working suddenly. The screen blacked out, none of the buttons on the control panel lit up. It did turn back on a couple of time when I was starting up the car in the following days. Then It was completely dead. AND it started to drain the car battery. The battery will not last for more than one day without driving. I checked the fuses, they were fine. I had to remove both fuses eventually to stop the battery drain.
Has anyone experienced similar problem with the McIntosh system? Any suggestions?
