Narrative:
After taking position on runway 3C at dtw we were given a clearance to turn left to 005 degrees cleared for takeoff. I read back the whole clearance, selected 005 degrees in the heading (select) window. The captain concurred and began the takeoff roll. At approximately 600 ft we began our left turn to 005 degrees and were handed off to departure. The departure controller asked us our heading and gave us a right turn to 060 degrees. We are not sure if we turned to an incorrect heading, because nothing was said, but a left turn off runway 3C is unusual. There was no conflicting traffic.
