Hi I have a 2004 A6 Final Edition which came with a the 2004 version dvd navigation. I had my frien copy his later version which was the 2005 map of western europe and the 2007 map of eastern europe. I placed the 2007 DVD map into my sat nav and it updated my system. I then went to put in the 2005 version of western europe and it does not work and neither does my original 2004 version of western europe. The only one which does work is the 2007 version of eastern europe. Which is of course very little use to me . Can anyone help or direct me me in the right direction...excuse the pun Oh there is a message which comes up on the sat nav screen which tells me to pay a visit to my dealer.....urrrrrrrrrrgh
