Narrative:

Cleared direct cqy, then cleared direct howdy intersection, then map and electronic route failed in FMS. Used backup navigation but we forgot we were cleared direct howdy and we proceeded direct cqy. About 2 mins later, center asked if we were proceeding direct to howdy. We told center we had a map failure and would continue direct howdy. We had no further problems. Center gave us a heading to intercept the arrival southeast of howdy.
