2015 Mustang Gt Compass Issue

[Paddymac]

I've made a couple posts before regarding the compass issues I have been dealing with. Long story short, I went from a Sync 2 to a Sync 3 module and have been having issues with my compass ever since (almost for a year). When it was initailly installed the installer put the gps antenna under the middle air vents. I eventually relocated the gps antenna to the proper postion, but the porblem continues. I've tried resetting the Sync 3 unit, but nothing seems to work. Has anyone else dealt with this issue before?

*Attached is a video with what the compass does every few seconds no matter what direction I'm facing.

I’ve tried it a couple of times with no success.

OK them, you may need to reset your APIM. Not sure if this can be done using Forscan.

Okay thanks!

Maybe it could be that you have one of the first ‘2105’ Mustangs and you’re so far into the future, we just don’t have the tech yet to diagnose....

Had the same problem when i changed my sync 2 to sync3 kit from hellhorseperformance.
What you need to do is take off the oem compass on top of the dashboard by the center speaker just disconect it and you wont have anymore problems.
