Narrative:

Flying from pit to ewr. As we were making our approach into ewr and being radar vectored, the captain (PF) asked me to identify the LOM and ILS frequencys. As I diverted my attention inside, the captain made a turn. The controller gave us a heading of 90 degrees and the captain thought the heading was 190 degrees. The captain was just rolling the wings to level when I finished identing the navigation radios. Just as I was getting ready to tell the captain the correct heading, the approach controller called to tell us we were on the wrong heading. We were turning into the path of other planes on final approach and turned back onto course. To prevent this from happening again we should have idented the navigation radios earlier so I could have stayed in the loop, helping to monitor the approach.

Narrative: FLYING FROM PIT TO EWR. AS WE WERE MAKING OUR APCH INTO EWR AND BEING RADAR VECTORED, THE CAPT (PF) ASKED ME TO IDENT THE LOM AND ILS FREQS. AS I DIVERTED MY ATTN INSIDE, THE CAPT MADE A TURN. THE CTLR GAVE US A HDG OF 90 DEGS AND THE CAPT THOUGHT THE HDG WAS 190 DEGS. THE CAPT WAS JUST ROLLING THE WINGS TO LEVEL WHEN I FINISHED IDENTING THE NAV RADIOS. JUST AS I WAS GETTING READY TO TELL THE CAPT THE CORRECT HDG, THE APCH CTLR CALLED TO TELL US WE WERE ON THE WRONG HDG. WE WERE TURNING INTO THE PATH OF OTHER PLANES ON FINAL APCH AND TURNED BACK ONTO COURSE. TO PREVENT THIS FROM HAPPENING AGAIN WE SHOULD HAVE IDENTED THE NAV RADIOS EARLIER SO I COULD HAVE STAYED IN THE LOOP, HELPING TO MONITOR THE APCH.
