Narrative:

First flight of day. New electronic flight bag (efb) installed. Given taxi instructions to runway xx. Distracted by new efb and glare on screen. My expectation bias was for departing on runway yy. During taxi on 'P' I turned on 'C' toward runway yy. Ground advised us of our mistake. We then did a 180 turn on the ramp and taxied back to runway xx via 'P'. Lesson learned is to try to avoid expectation bias by better preflight briefing. Having an IOE student didn't help.
