Recommended Application for DGN viewing for field users

Good morning, all.

Does anyone have any recommendations for which application would be best to view DGN files for employees in field? I would love to enable our field crews (survey, environmental, construction, other) to open a DGN with its references attached and be able to view the file. Even better would be location awareness with the files that are geolocated. We have played around with a couple different options, but so far it is cumbersome and usually not worth the effort.

Any ideas?
