I am fairly new to augmented reality implementations, and have been handed down a project which used Junaio sometime back in 2012. I need to re-implement everything from scratch, and I think I've been fairly successful so far; I can get my POI's to show up on a map and in the list, however the 3D Models for those points and thumbnail/icon images for those POIs do not show up in the app when I load my channel. Here is an example of the XML being used for one of the POIs. Is there something I'm missing?

the best way to find support for that is on metaio helpdesk. maybe this helps: http://helpdesk.metaio.com/questions/17632/gps-tracking-scale-over-distance
