Hi All,  Newbie here.   Got into my 2008 X Type estate last week and put an address into the Sat nav.
 
	It was calculated and i told it to set as destination and start.   as i moved off from Home, the Nav seemed to move off the roads i was on!
 
	It now believes i am actually 40 ish mile southwest of where i am.  I have gone into the menu and reset my location, but as i move off it goes wrong again.
 
	Anyone got any ideas.    I've also removed and reinserted the disc.
 
	Thanks
 
	Tony
