V70 Cabin heaters - available in UK?

[jinkster]

Are cabin heaters available in the UK for the V70? Which model and which year generally has it.

(basically its like a little diesel heater that you can start remotely from what I understand)

Thats the one! Will be really useful in this weather to pre-heat the car instead of scraping the global warming off the car at 4am!
