$320 on eBay and the directions that came with it are easy enough to understand. It's just a matter of doing the work which may take longer because you're scared of pulling kick panels off but everything went well. Took about an hour and a half, if i wasn't hesitant, maybe less than an hour.
The specs state that the heated steering wheel is optional, even for the GT2, but it is not included on the Options selection page. I hope that it being an option is a misprint in the spec sheet.
