Narrative:

While in cruise flight we noticed the #2 mcdu start to flicker and go blank. Shortly after that occurred we noticed a electrical burning odor. We coordinated with dispatch and decided to divert to ZZZ; but changed our minds and decided iad would be closer with good VFR weather. We were set up to go to 19C but got approval for 19L since we were going to [the FBO]. While cleared for the visual to 19L we over shot the center line. ATC reconfirmed that we were cleared the visual to 19L. We quickly made a correction to get back on the center line to 19L. Tower made no indication that this was a reportable event. Crew saturation. Many changes over a short period of time.

Title: CE680 flight crew experiences an MCDU failure in cruise flight and elects to divert for maintenance. Shortly after the failure an electrical burning odor is detected and the crew elects to divert to a closer airport. A very busy descent and approach results in an overshoot while attempting to intercept the localizer. A normal landing ensues.
