Saw this on clearance at my local Currys (Solihull) and probably same price in any Currys (any DSG?) subject to stock as it has now been replaced by 2009 models.
I paid £129 for mine last year and still think it was a good buy. Large (4.3") touchscreen, accurate, easy to use, includes Bluetooth (phone hands-free) and 'safety' camera database.
No longer shows on Currys' website so link is to NavMan site for spec details, etc.
Hope it helps someone!
