Narrative:
Gfms was placarded OTS. This also takes the GPWS OTS. I did not see the GPWS placard in the logbook until it was time for the terrain briefing at the end of the runway for takeoff. Upon checking the MEL, I realized the aircraft was not legal for flts into mexico without the GPWS. We taxied back to the gate and substituted aircraft. Suggest aircraft with FMS not be dispatched to mexico if FMS is OTS, as it is tied into the egpws.
