Garmin Montana 700 as a Roadbook Reader

Hi

Nowadays, most of the off-road events are Roadbook driven. Some are on paper only, but I find most of them handling a digital PDF.

I would love to be able to use the Montana 700 as a Roadbook Reader. My group are using the Samsung tab active 3 because they have a lot of choices (and free). 

Is it possible to develop and app that reads a .PDF and shows trip and cap head?

Thanks!
