Most dealers won't do euro update. However, many indie's, and of course some of this board's sponsors will be more than happy to help you out. There is also a board member (I think his name is Alex?) that offers a remote service that many members have reported back positively on.
I really want to get the Euro SMG done by Alex at Alpine but I've read posts where people in NY haven't been able to pass inspection due to some OBD related issue. I have inspection coming up in March, I might go through it earlier and get the euro flash after I pass.
