On multiple occasions HDG on Garmin G1000 has 'X-ed' out for 2 seconds to several minutes. This causes me to cancel my IFR training mission multiple times and return to base. I have attempted to have this issue resolved by several certified avionic technicians to no avail. After online research I have found blogs describing the same issue; so this is not happening to just me. My avionics technicians have had communication with both Cessna and Garmin about the issue. Apparently; both Cessna and Garmin are aware of this and are saying it is a software glitch. I consider this to be a 'Safety of Flight' issue since I could lose HDG during IFR in a critical situation and it appears to be across the aviation community with Garmin G1000.
