One try more.....thanks for answer.
I saw a video the area 660 worked great together with Foreflight. Have a look. https://youtu.be/mBnv88S4tj4
Wondering why it does not work with SkyDemon? It would be great if area 660 / 760 can share and exchange data like Foreflight can do. The SkyDemon NAV app is very popular and widely used in Europe, especially in UK, Scandinavia, Germany, France, Italy,... It would become to a backup solution to exchange flight plans between area devices series and SkyDemon. This is may a good reason to sell more devices into the market as a backup solution for less reliable tablet solutions.
