Rear view mirror heated or not? (pre-wired?)

[Freeday]

Hi folks

After hitting a pole with quite a bit of speed the glass of my right rear view mirror of my
2012 T300 "fell off". It was only the glass falling off, hanging down on 2 cables.

The mirror steering seems to be separate from those cables.

Does this mean the AVEO is pre-wired for heated mirrors? As i live in Switzerland and it
can be painfully cold outside this would solve a BIG problem. Is it only a switch change then?

Could somebody pls. check on an LT or LS if there's a wire holding the mirror glass and if this
is for heating?

THANKS
Stefan

p.s. The glass could easily be clipped in again and everything still works perfect!
80 km/h smack and not a single dent on the mirror housing!! Built tough :P
