Ok i have an S3 with the satnav as above in the title. I work in Falmouth in Cornwall and yesterday turned the satnav on and changed the display to show my position on the map. It showed me as being somewhere in Penzance and today whilst in Falmouth it showed me as being over in St Ives! I don't really know when the fault started but i only noticed it yesterday as i hardly use the satnav.... What might be causing this error??
