My sat nav was working fine up until two days ago. All of a sudden it doesn't seem to be picking up any satelites.
When I go to Mode-settings-GPS view it shows 31 satelites available but it#s not receiving any.

When I drive the map moves but it's not showing where I am, it just thinks I'm off road.

There is a fuse for navigation but it's fine.

Does anyone know whats up? I hadn't touched any cables or installed any other hardware, it just stopped working?????

Any suggestions would be very welcome......
