Narrative:
Entered bjc class D inadvertently. Upon xchk of GPS (garmin 430) realized false GPS indication. Immediately contacted bjc tower to notify and left class D airspace to the west. Entered class D airspace by 1.5 - 2.5 mi. Latest download for garmin 430 does not show class B; class D for denver area. One cause to contribute was first flight after maintenance. I was checking autoplt; etc; for proper operation. Distraction.
