Hello I have a strange one, Last week the clock on the sat nav (top right) decided to put itself back an hour. Not a problem perform the reset that have read about on this site, nope not worked when I go into the 'where am I setting GPS' it is showing connection too two or three satellites giving me the correct location. I have tried setting the time too London and also automatic but it still refuses to update. Has anyone got any ideas on this? It is a T31 2007 aventura.
