Subaru XV 2013: Out-of-date maps

I recently bought a new Subaru XV and have since been told by Subaru that the most current maps they have available are the 2011 maps, and that it's my responsibility to source and pay for updates. I would have thought it was reasonable to be provided with up-to-date maps in a brand new car, and further when it is standard equipment on the car I would expect the maps to be updated automatically when my car goes in for service, much like they update the computer in the car. I don't know why this part of the vehicle is being neglected. I have spoken with my dealer and Subaru has not provided him with any updates either. I think this is very poor and Subaru needs to take responsibility and provide updates free of charge to cars while they are under warranty and maybe even for the life of the vehicle. My $200 Navman gives me free updates for life, so it's obviously easily done.
