I've called them twice about it, spoke to two different customer care reps, who in turn each spoke to the sales and marketing department for me. Both times, they said the same thing - it is currently under consideration for the UK market, but they cannot say if/when it will be available and at what cost. I would assume that if you had a car without it, and then it became available, it would be something that could be retro-fit and at worst, simply wired into the existing heated rear screen switch. Time will tell...
