I had the dealer update mine from 2010 to 2011. There was no meaningful improvement in map coverage or routing intelligence (?). And it cost $650 for the dealer to do the install. From other threads, there is a relatively wide range of prices, depending on the dealer. But all are outrageous.

There is a complete thread on DIY for this. While the thread is long, there is a good explanation at #138. See link.
