Hi, my headunit (Alpine CDE178BT) is draining my battery within a couple of days - but strangely it has only recently started doing this. I had someone confirm that the stereo was draining it, and after unplugging it altogether the battery has been fine.
I've tried switching the red / yellow wires around but the unit still powers on without ignition. How would I completely cut power to the headunit when turning ignition off? I would prefer not to as I'd lose my settings but it would be better than nothing!
