I also ordered a wood dash kit this week. They have made the adjustment for the Limited heated seats and the kit is ready to go. I went with a B&I kit because it had pieces to cover all of the Limited's granite pieces. It should look great, I will post pics once I get it installed.
Here is a link for B&I

Go to flat kits, then to Toyota. It seems like nice stuff. I'm told this is what the dealer uses and charges $800+ for.
Cheers,
