Narrative:

I was at FBO in sba and was given taxi instructions to runway 15L. I told the controller I was unfamiliar and asked for progressive. He told me to taxi via taxiway B. I saw taxiway B on my garmin 'safe taxi' GPS and proceeded through the ramp. When I got to the taxiway; the 'B' had disappeared from the screen and not thinking; I taxied on the same route; as I had just arrived and crossed an active runway. 1) I did not verify visually outside the cockpit. 2) I assumed that a 'progressive' would keep me out of trouble.
