Replacement Power Heated Mirrors

I really, really want to replace the factory power mirrors on my '07 Taco with heated power mirrors but the only ones I can find are the Muth glass replacement kits. I'm not averse to performing the Muth installation myself (more than capable) but I'm wondering if somebody makes a direct replacement of the entire mirror assembly or if heated mirrors were even available from the factory, maybe Canadian trucks? Someone posted on the Toyota Nation web site that the Tundra had a cold weather package (cheap too, only $100!) but nadda for the Taco. I had power heated mirrors on my old Dodge minivan and since I live in the mountains of PA, heated mirrors are dang near essential and more than worth the money. I didn't realize just how nice they were until I didn't have them anymore! (Even my wife's little Subaru Outback has them.) Does anyone know if these exist or if it's even possible to use Tundra mirrors?
