Narrative:
While tracking westbound on V100 between elx and musky; chicago center inquired as to our position north of course. We responded that we were showing on course; and stated we are tracking the 277 radial outbound from elx. Center replied that we should be on the 271 radial. I input the 271 radial and intercepted the course. Upon further investigation; our navblue charts+ show 277 course westbound on V100; while FAA issued charts show 271. In addition; navblue charts+ show a change from 277 to 274 after passing yolur intersection. With no navaid located at yolur; how can the course change? We were navigating in green needles because the aircraft had 3 mels at the time.I suggest a review of the navblue charts+ enroute charts to determine if accurate data is being presented to pilots using the charts.
