Wilco737Pic Heading problem

Since i am still gettign use to the reality of the Fsx Wilco 737PIC, i have another problem im not sure how to fix.

When doing an IFR Flight, The controller will tell me to turn a certain heading, so i set the heading into the autopilot and it turns to that heading, but that heading is wrong because wehn i am at my heading i was told to go to, the controller says over and over to turn to the heading, when i already at the heading.

So i look at the Fsx map, and it says a whole different heading then what i see in the plane.

For example, the controller tells me to turn to say 190, so i set that in my autpilot and it turns to 190, but the controlelr says i not at the right heading, so i look at the map and it says somthing like 350, so then all correct that on the map but then going back to my plane, it will say im at a whole diferent heading.
It's hard to explain this problem but if someone knows how to fix this problem it would be greatly appreciated.

someone?

anyone know this or not?

Dosn't anybody ever go on this site anymore?

Sorry, I fly simple GPS, can't help.

NeverMind i found the problem, i didn't have my IRS set up correctly.
