Narrative:

The captain accepted a direct clearance to a fix with our RNAV unit when it was MEL'ed inoperative. I asked him if he was sure he wanted to do this and he said 'yes.' we used this 'inoperative' piece of equipment for primary navigation of the flight. He also had me change our flight plan to ia, but we accepted a direct clearance anyway.
