Narrative:

I was flying an aircraft equipped with a G1000 for the first time in nearly a year. I trained a lot with that type; but then moved on to retractable gear to work on commercial/CFI certification. Normally we leave yip at 2500 due to dtw airports class B shelf above us at 3000. I climbed to 2500 using the autopilot and didn't notice I had not armed the altitude; so it continued to climb. I noticed my altitude was too high about 2950 and disarmed the autopilot; and I stopped the climb as quickly as possible without startling my passengers; but unfortunately the altitude did register 3000 or 3020; after which I quickly descended to 2500. This happened near the top corner of the bravo airspace near the semi-circle gap around the svm VOR; probably about 1/2 nm to 1nm away from the edge of the airspace.
