Hi, I've upgraded my nav system from SW 2-1/24 to the latest v27.1. All loaded O.K and I now get SW 2-1/81. Problem is I still can't do a postcode search other than London postcodes (I could do that with the old system) and I can't get perspective view. I've tried going to set and holding menu down for about 10 seconds but when the service mode screen appears there is no perspective setting. I know it's not on the first screen that shows but when I scroll down there isn't a second screen.I 've tried loading it again but no luck. Any help would be GRRRRRREAT! Thanks
