I have them in mine. They are already set up from the factory because the Canadian Yaris has them optional. Had to install the switch myself. Got from a cx3. Not worth it in my opinion they don't really get warm. Also you will have to disassemble quite a bit of the dash as the switch is replaced the one that tells you if the passenger seat belt and airbags is on... I will post a picture tomorrow.Did anyone have heated seats added to their car? I'm thinking of having it done but i'm nervous of where they will post the control for the seats and if my seats will still look the same.
You have to take apart quite a bit of the dash and center console to get to the part you want to replace with the heat switches. Like I mentioned in the comment before yours, my car doesn't do anything except light up the heat seat buttons. No heat. I'm actually questioning whether the seats have the elements needed as others have stated. Someone did install the switches and they did say they felt the seat getting "warm" but its very subtle. I'm wondering if that's just body heat that's warming up the seat. They also said it wasn't worth the $100 for the part and imo, it wouldn't be worth the money or the effort to do so, unless you like having heated seat switches on your dash.With the cold weather up in the northeast now, this is a very interesting option. Is this in fact as easy as it seems ? Just installing the switch activates the already installed heated seats ? If so, that's next on my list. I noticed on the Canadian Toyota website, the "Premium 6AT" model of the Yaris iA has heated seats included, while the other two basic models do not.
