Narrative:
Prior to push I called clearance delivery to check and see if we needed an amendment to the clearance due to recent software issues with the FMS. They said no this departure is fine. As we started our initial climb the intercept fix and first GPS fix moved to different locations on the mfd causing the flight director to show a right turn instead of left. I flew for another few seconds and asked the captain to get us a heading. When he decided to do so ATC assigned a left turn. Recent issues with the 27.1 honeywell software. Have sfo clearance delivery issue headings until it's fixed.
