Narrative:
Location: 340 degrees radial 40 DME agu-en route. We were being rushed out of dfw. The agent and ground crew were ready 14 mins early. We expedited through our checks, but I did not double-check our routing on the GPS. En route we experienced a hydraulic problem that took up a lot of my time, talking to maintenance and dispatch. Our route after cdr was UJ11 but we had direct gdl in the GPS. Mexico center called us about 40 DME northwest of agu and told us to go direct agu. We did with no conflicts. I believe that we were approximately 15 mi west of UJ11 centerline when we made our course correction. I should have been more diligent in checking the gfms before we left. I felt a little rushed. If we had not had the hydraulic problem en route I would have caught the error. I always have my navigation charts out for backup but I was behind this time due to our problem. I have to remember to fly the airplane first.

Title: AN MD80 CREW, ENRTE TO MMGL, DISCOVERED THE GPS WAS FALSELY PROGRAMMED WHEN ATC ISSUED A VECTOR TO INTERCEPT THE FILED AIRWAY.
Narrative: LOCATION: 340 DEGS RADIAL 40 DME AGU-ENRTE. WE WERE BEING RUSHED OUT OF DFW. THE AGENT AND GND CREW WERE READY 14 MINS EARLY. WE EXPEDITED THROUGH OUR CHKS, BUT I DID NOT DOUBLE-CHK OUR ROUTING ON THE GPS. ENRTE WE EXPERIENCED A HYD PROB THAT TOOK UP A LOT OF MY TIME, TALKING TO MAINT AND DISPATCH. OUR RTE AFTER CDR WAS UJ11 BUT WE HAD DIRECT GDL IN THE GPS. MEXICO CTR CALLED US ABOUT 40 DME NW OF AGU AND TOLD US TO GO DIRECT AGU. WE DID WITH NO CONFLICTS. I BELIEVE THAT WE WERE APPROX 15 MI W OF UJ11 CTRLINE WHEN WE MADE OUR COURSE CORRECTION. I SHOULD HAVE BEEN MORE DILIGENT IN CHKING THE GFMS BEFORE WE LEFT. I FELT A LITTLE RUSHED. IF WE HAD NOT HAD THE HYD PROB ENRTE I WOULD HAVE CAUGHT THE ERROR. I ALWAYS HAVE MY NAV CHARTS OUT FOR BACKUP BUT I WAS BEHIND THIS TIME DUE TO OUR PROB. I HAVE TO REMEMBER TO FLY THE AIRPLANE FIRST.
