I updated a friends 2011 E220 with this and now it says 'Navigation Unavailable please insert the Navigation DVD'. The process seemed fine and it loaded up version 9 ok. When you put the DVD in it just goes to 100% again and comes up with this message. I was lead to believe that this may need a firmware update for the Command software? This allegedly is on the DVD but it didnt seem to do anything other than the map upgrade.

His old maps were v6 Audio APS 50 which i replaced with the v9 on this forum.

What do i need to do now to get the 2013 map working?
