We just picked up a 2002 desert sand Sequoia SR5. We got the SR5 rather than a limited b/c my wife wanted the desert sand color, which isn't available in the Limited version. We were able to get just about every option we wanted, except the heated seats. Our dealer has a company in Seattle that can retrofit heaters on our existing seats, but it won't be stock, and they don't use the system/buttons that are in the Limiteds.
Do any of you know of a way to get stock heated seats in an SR5, or at least use the heating activation system in the Limiteds, to activate retrofitted seats?
