Qashqai satnav not finding my location

Hi

Cars been fine but the last week the satnav location arrow on the map isn't showing me in the right location
You can also check your location and there's no cooordinates appearing of where I am in the settings.

I've had the battery off for an hour, I've reset the radio which is fine and I've had the aerial off as well
Beyond that is a it technical for me.
I can only think that something's worked loose behind the head unit
Thoughts very much appreciated

Swmbo flattened the battery onthe school run today so I charged the battery and it's decided
To work again
