Along with the many other "Morrisons Reduced" threads at the mo - Morrisons have also reduced the Navman S70 3D down to £50.
Not sure if they'll be in your local Morrisons, I got mine from Coalville today. They also were reducing they're mobile phones down to half price and Oregon 2k headcams down to £29 as well!
As for the Navman pretty good write ups and seems a bargain for what you get. Not exactly the most of aesthetic of items compared to my Navigon, but will be great for the father in laws Christmas present! Certainly cheaper than anywhere else on the net.http://www.navman.com/in-car/europe/uk/Products/Sat-Nav-Devices/S70-3D/
