The audio system that you have looks like its same as the 2005-2007 Pathfinder models that were sold in North America. The new nav system for the North American 2008 Pathfinder looks quite a bit different and has a 9.3GB harddrive with a back up camera. Check out Nissan's website and you'll see the difference. http://www.nissanusa.com/pathfinder/index.html
The european models probably have slightly different hardware with different part numbers than whats over here in North America.
I have a 2007 Pathfinder LE and my bose audio system looks similar to yours even though I don't have the nav system.
