I stopped at the Aire de Rumaucourt and accidentally closed the Navmii software.  When I started the software and tried to navigate to the Eurotunnel arrival road it said Cannot Calculate Route. The Navmii software showed us travelling on the A26.  After several Kilometres to was able to navigate to the saved Eurotunnel Favourite.  We were travelling from Troyes and I also noticed it tried to take us via the A29 to Eurotunnel (which I ignored and also via junction 8 on the A26)

Cheers
