I have bought a 2010 A5 with the nav cd is locked in the tray. I looked on Ross Tec Wiki and it said to go into 'Radio' - 56 and alter the value in channel 68 to 1 or 0. when I go into it channel 67 & 68 come up as Not Available. When I researched it further it suggested to try 0E but this controller can't be found.
Has anyone any idea why I cant find the channel or re-set the value?
Thanks
