Anyone ever had any issues with their heading indicators (pri and stby) as well as the gps showing about 180 degrees off on the ground, and constantly fluctuating in air? Taking off on KMIA Rwy 9 shows a heading of 276 centerline and in the air IFR to Cleveland the GPS and heading indicator fluctuate between 150 and 360, causing autopilot at cruising altitude to go nuts.
I've used the keyboard for calibrating the compass but nothing changed. Ive even tried uninstalling and reinstalling FS9. Same issue. The only things I've changed is I've recently installed ImagineSim's KDEN (I doubt this is the issue), as well as, playing around with the ProjectOpensky 737-900 model and finally installing the PMDG 737NG package. Is there something in the aircraft.cfg for the PMDG that could be causing this? Even so I've deleted the installation completely, tried flying the default C172 and had no change in the heading malfunctions. The failures are currently turned off as well.
