@ H@mlet,

Sorry, there are currently no resources to develop a specific mobile browser enhanced version of the map. We tested navigation successfully on Android 4.1 with Firefox. However scrolling of the map is incredibly slow but that's a question of mobile device memory and performance and also of available internet speed.

Regards.
