New avionics (Garmin 750) incorrectly showed boundaries of San Francisco Class B. I descended to 6000 foot to be below outer sector floor. By time I double checked (iPad) I was near the 4000 foot floor sector and descending rapidly. I may have been slightly above 4000 feet after entering the 4000 foot floor sector. When ATC advised me of the problem; I was already in a rapid descent.
GA pilot reported a problem with a new avionics platform that seemingly caused an airspace incursion.
