well wot i did was , after doing a gpsquickfix...,which i personally think s**te , cause it didn't actually do owt , was a ' pin' reset , which again did nothing other than reset the clock time , - i took it back to a great catologue store ( no names), swapped for a new and alls fine again , the unit was only 2 weeks old so i ad the comfort of that , and i will do it again , an again..these pices of kit must be the most unreliable electronic gadget going , ya can turn ya telly on everytime and get a picture ( signal), same wi ya mobile phone , but sat navs...oooeerr...........
