Narrative:

I had been cleared to descend to 5000 ft MSL and was told to go direct mygal. At 4500 ft MSL, ATC called my attention and said to descend to 4000 ft MSL. I was too busy trying to find mygal and program the (commercial mfg navigation aid) to find the waypoint. I was single pilot at the time.
