Apparently , it was option number M577 at some point (heated & tinted).
Is there an on - off switch ? If so , where is the factory location , and what type of switch ?
And if anyone knows what year this option was 1st available , please do tell.

I was seriously considering fitting this option after the fact, when I replace my 250,000+ mile original. I'm told the on/off is the rear defrost knob; on cars with a heated front screen, you apparently twist it for heat on the front.
