Narrative:

While flying a training flight in VFR conditions with an instructor/safety pilot we discussed flying the GPS 07 approach into the grass valley airport. We elected to fly it with vectors from the instructor as I had not flown much IFR or simulated IFR with the avionics equipment we had on board. The aircraft was equipped with a garmin 750 GPS and a garmin 530. I also had my ipad up with the approach plate for the approach. I have the upgraded subscription (pro) that shows the actual position of the aircraft on the approach plate. We are both familiar with the local area and airspace from a VFR standpoint and regularly deal with ATC for transitioning through beale's airspace/tfr; however neither of us had flown this GPS approach before and didn't realize that mrgoo; the IAF is actually within beale's class C airspace and subsequently in the tfr. Doing the approach ourselves rather than getting with ATC; norcal or beale; put us into the tfr on both the approach and the holding after the missed approach. Contributing was that the instructor had the 530 display up to show the intersections; the ipad approach plate does not show the class C and the auto zoom function of the garmin 750 zoomed us in to where we could not recognize the boundary of the class C airspace. We discovered the problem when we switched the 530 over to the map page and could clearly see the airspace depiction. We certainly had plenty of technology to use; but needed to understand the limitations that comes with and be aware at all times of what airspace we are in or headed too.
