Hey schanmala,

Just went and checked mine and it's also the 2010 version. Had my suspicions it wasn't up to date when I couldn't an address that was two years old.
Let me know how you go with the dealer, maybe tell them it's being discussed on the forum. I didn't even know about the cable harness to connect a Subwoofer. For the price we pay you'd expect to get the free updates.

Cheers
