Narrative:

We departed off runway 25R from lax. We were assigned the orcka 3 SID; given 'climb via' the SID except maintain 5;000 feet. The SID has a discontinuity between initial RNAV fixes into an assigned heading transition to 'expect' a turn to the klipr fix.I was pilot flying and hand flying the departure. When we started on the 236 heading (heading); I asked my copilot to double check the chart to see if that heading should be continued or if we had a another turn. He said we needed to turn towards klipr; so I began the turn. Since I was hand flying; I did not pull out my efb (electronic flight bag) to double check and glanced at the chart my copilot had displayed on his efb. The turn; however; was not authorized and we were queried by the controller as to why we were turning which was my first realization that I had deviated from my clearance. He then vectored us per his discretion back onto the arrival.after reviewing the issue with my copilot; I realized he was looking at a naco (government published) chart; which had a graphic depiction of the turn to klipr being next. He did not understand the symbology of the naco chart whereas the dotted lines represented 'assigned' track vs. 'Own navigation' track. He did not read the narrative therefore he did not understand that the turn to klipr must be assigned vs. 'Own navigation.'as PIC (pilot in command); I utterly failed to review the SID narrative thoroughly enough to understand what the copilot was directing me to do was incorrect. I bare sole responsibility as my copilot is very low time; and was not experienced with operating out of lax.I could have avoided this by executing a much more thorough review of the SID prior to departure and using CRM to ensure both myself; and my copilot understood the SID. I will also add that the naco graphic depiction of this SID was confusing even to me; as I had not immediately remembered the difference between a dotted track and a solid line track; as I am accustomed to using jepp charts. I should have called for the autopilot; then checked the chart myself; prior to making the unauthorized turn.
