Thanks to you all I set up the Navigation correctly a few weeks ago and all worked ok but today I set a destination clicking on history and chose the route and although is came up on screen with details inc. time of arrival etc on l/h side all that happened as I drove the journey was a repeated voice saying 'route re calculated' and a warning of overspeeds - the route itself showed as I drove it but no voice directions!
When the route appeared on screen I clicked on destination at bottom of screen and then on navigation.
What have I done wrong as it worked ok a few weeks ago?
Thanks
Gordon
