Hi Sorry for the delay in responding. They are the very people I mean and two separate discs have failed to work for me. One updated the firmware but neither disc is recognised as a sat-nav DVD - frustrating. Thanks for the welcome. Steve
Just saying 'hi'. Just joined S type (2.7 diesel) owner. Had the car about a year and love it. Always had Mercs and Audis before then but test drove this car and was smitten. Only bug-bear is the price of a sat nav update. I have had discs from the usual alternative source and neither worked - although updated the firmware.
