Mirror is heated or nonheated?

I have a Toyota camry 97 with power mirrors. I want to change one of side view mirror (RH) which was broken. How do I know this mirror is heated or nonheated? any suggestions will be appreciate. :confused:

If that one is heated, both are heated. Start your engine and turn on your rear window defroster in the shade. Spray some water mist (like from a spray bottle) on the driver's side mirror. If the mirror is heated, the water will evaporate from the center outward within a couple of minutes. If it is not heated, the water will just look at you for more than 15 minutes.
