There was a major revision to the satnav/in-car entertainment for the MY2010 model. If you are looking for one with Satnav, either make sure they take a big chuck (ie almost free) off for a MY2009. Depending on the price difference I would (and have) go for a MY2010. Search for my thread on "Connect Premium" to see the differences between the two.
Other than Satnav, no real revisions made, so you could save yourself a few bob if that doesnt bother you.
Bloody hell chris that was quick lol
