View I-Model on iPad

Hi forum,

Trying to view an imodel on the iPad. I've created my i model, published it via Publisher, put it into Dropbox... but that's where my trail to view it on the iPad ends. Navigator instructions end at this point and it doesn't tell you how to get it from your cloud service onto Bentley Navigator Mobile? i cant open it from Dropbox with Navigator and the Navigator App itself doesnt appear to have a 'find' or 'gotoo' folder button. It seems to have 3 standard demo projects on.

Am i missing something simple?
