Narrative:

I was monitoring my position on my new garmin 396. The moving map showed the presidential tfr with a cutout for the ZZZ departure. I was in the cutout area and climbed to a VFR altitude of 3500 ft forgetting that the class B was above 3000 ft in this cutout area. The controller questioned whether I was familiar with the class B airspace. I certainly was; but had been distraction by the new GPS and tfr marking. I should have referred to the sectional chart instead of relying on the GPS depiction which did not give the floor of the class B in this cutout. Callback conversation with reporter revealed the following information: reporter had used a similar unit once several months prior to using the new GPS for this first time flight. The device automatically loads route information; tfr's; WX; etc; and reporter finds it a good flight aide. Because the tfr display information at the time of this flight was abutting a class B area; the actual tfr information covered the class B information that would normally be displayed. The reporter does not find the new technology distracting but acknowledges that the paper charts should be consulted prior to relying on the electronic information.

Title: A C177 PLT WITH A NEW GPS CLBED INTO CLASS B AIRSPACE BECAUSE BOUNDARY DISPLAY INFO ABOUT A PRESIDENTIAL TFR COVERED CLASS B ALT DISPLAY INFO.

Narrative: I WAS MONITORING MY POS ON MY NEW GARMIN 396. THE MOVING MAP SHOWED THE PRESIDENTIAL TFR WITH A CUTOUT FOR THE ZZZ DEP. I WAS IN THE CUTOUT AREA AND CLBED TO A VFR ALT OF 3500 FT FORGETTING THAT THE CLASS B WAS ABOVE 3000 FT IN THIS CUTOUT AREA. THE CTLR QUESTIONED WHETHER I WAS FAMILIAR WITH THE CLASS B AIRSPACE. I CERTAINLY WAS; BUT HAD BEEN DISTR BY THE NEW GPS AND TFR MARKING. I SHOULD HAVE REFERRED TO THE SECTIONAL CHART INSTEAD OF RELYING ON THE GPS DEPICTION WHICH DID NOT GIVE THE FLOOR OF THE CLASS B IN THIS CUTOUT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR HAD USED A SIMILAR UNIT ONCE SEVERAL MONTHS PRIOR TO USING THE NEW GPS FOR THIS FIRST TIME FLT. THE DEVICE AUTOMATICALLY LOADS RTE INFO; TFR'S; WX; ETC; AND RPTR FINDS IT A GOOD FLT AIDE. BECAUSE THE TFR DISPLAY INFO AT THE TIME OF THIS FLT WAS ABUTTING A CLASS B AREA; THE ACTUAL TFR INFO COVERED THE CLASS B INFO THAT WOULD NORMALLY BE DISPLAYED. THE RPTR DOES NOT FIND THE NEW TECHNOLOGY DISTRACTING BUT ACKNOWLEDGES THAT THE PAPER CHARTS SHOULD BE CONSULTED PRIOR TO RELYING ON THE ELECTRONIC INFO.
