Magnetic Compass Issue

[blemoine]

When I start in KSNA my magnetic compass and heading indicator are off by about 90 degree. If I start at KATL the magnetic compass and heading indicator are correct. GPS and all NAV's are off. I looked on Google but could not find a solution. Any help is appreciated.

FSX with SP2, new install and setup. This issue was from the initial install. I deleted the system (OS, everything) and installed again, this did not help.

If I load a new flight and start at KSNA on 1L, my magnetic compass indicates about 13 degrees.
If I load a new flight and start at KRYY on 27, my magnetic compass indicates about 274 degrees

Thank you!

What number are you expecting to see when you start on 1L at SNA?

Seems pretty close to me.....01L should be 15°

I have installed several add-ons and updates after last testing. looks like one of them fixed the issue. I performed a flight from KSNA to KCRQ, all seemed to work no issues with the Compass or GPS.

Thank you again!
