Narrative:
Departure course deviation. We were cleared the wyldd 1 RNAV departure out of las. Prior to pushback, we received 'read before fly bulletin' which said to expect radar vectors from departure to a segment of the RNAV departure. Tower cleared us for takeoff and did not give us a heading, so we flew the initial RNAV departure heading. Tower handed us off to departure control and I checked in, the departure controller acknowledged and did not give us any vector to a point. I was expecting a vector as per the 'read before fly.' I queried the controller twice but got no response. The departure frequency was very busy and it was tough to get a word in. The controller finally responded and seemed confused by my question. In the midst of this, we overshot our turn point on the RNAV departure, which I was not sure that we even were supposed to be flying. The departure controller asked about our turn and gave us a heading back on course. He seemed intent on us flying the whole RNAV procedure. The issuance of this 'read before fly' contradicted our actual clearance and created confusion. The departure controller seemed confused also. I should have clarified this discrepancy with tower on the ground before takeoff.

Title: WITH A COMPANY BULLETIN SUGGESTING THAT RADAR VECTORS ARE TO BE EXPECTED, A FLC EXPECTED THAT AND NEGLECTED TO FLY THE WYLDD RNAV 1 DEP FROM LAS VEGAS, NV, AS THEY WERE CLRED TO DO.
Narrative: DEP COURSE DEV. WE WERE CLRED THE WYLDD 1 RNAV DEP OUT OF LAS. PRIOR TO PUSHBACK, WE RECEIVED 'READ BEFORE FLY BULLETIN' WHICH SAID TO EXPECT RADAR VECTORS FROM DEP TO A SEGMENT OF THE RNAV DEP. TWR CLRED US FOR TKOF AND DID NOT GIVE US A HDG, SO WE FLEW THE INITIAL RNAV DEP HDG. TWR HANDED US OFF TO DEP CTL AND I CHKED IN, THE DEP CTLR ACKNOWLEDGED AND DID NOT GIVE US ANY VECTOR TO A POINT. I WAS EXPECTING A VECTOR AS PER THE 'READ BEFORE FLY.' I QUERIED THE CTLR TWICE BUT GOT NO RESPONSE. THE DEP FREQ WAS VERY BUSY AND IT WAS TOUGH TO GET A WORD IN. THE CTLR FINALLY RESPONDED AND SEEMED CONFUSED BY MY QUESTION. IN THE MIDST OF THIS, WE OVERSHOT OUR TURN POINT ON THE RNAV DEP, WHICH I WAS NOT SURE THAT WE EVEN WERE SUPPOSED TO BE FLYING. THE DEP CTLR ASKED ABOUT OUR TURN AND GAVE US A HDG BACK ON COURSE. HE SEEMED INTENT ON US FLYING THE WHOLE RNAV PROC. THE ISSUANCE OF THIS 'READ BEFORE FLY' CONTRADICTED OUR ACTUAL CLRNC AND CREATED CONFUSION. THE DEP CTLR SEEMED CONFUSED ALSO. I SHOULD HAVE CLARIFIED THIS DISCREPANCY WITH TWR ON THE GND BEFORE TKOF.
