Archie's and ACSI poi on t6 sat nav

[Speleo62]

We are off to France on Friday . Anyone got any advice how to add asci and/ or Archies to T6 sat nav. We tried Welsh gas' download but it wouldn't recognise it. The whole info system is a bit of a mystery. We have them on IPad. Also any recommendations for campsites aiming for Chamonix, especially near Calais as on evening euro tunnel.
Thank you

We just use the iPad.
Our favourite Calais campsite is Chateau Gandspette http://www.chateau-gandspette.com/campsite-france-pas-de-calais.html only 25 minues away from Calais or Dunkderque.
