Heated Outside Mirrors?

I have read that the Canadian Frontiers come standard with heated exterior mirrors. Anyone here know if the US Frontier is pre-wired to accept them?

Heated mirrors are also standard on the Pathfinder LE here in the US so getting them shouldn't be a problem. Getting them to work on a US Frontier may be more difficult and could require changing the subharness in the doors which could be expensive.

Thanks,
