Map Spinning/GPS issues

[F150Chief]

Did you disconnect the GPSM when you upgraded to Sync 3 from Sync 2?

EDIT: I searched and see you did disconnect the GPSM…

Every journey i do, the map will always spin here and there (also the compass in IPC spins with it). There are occasions when the arrow is not even on the road and it eventually finds its way back.
I’ve installed the new version along with F10 maps, has anyone else experienced the map doing a rotate whilst driving in this version(or any other versions). If I put it fixed north mode the rotate issue doesn’t happen, but if I put in the other 2 modes, every 10 seconds or so it spins/rotates.
I purchased it secondhand in October 2019. It came from a crashed Mondeo and I didn’t find out what year it was unfortunately.

This does not appear to be an APIM programming issue, but looks more like a communication issue between the IPC, APIM, and BCM. Or it could be just loosing GPS lock. I have noticed that the display will move more and have more corrections in other modes than “North” mode.

Is the data above for the APIM in the car now? If the unit came from a Mondeo like yours, it should be ok for programming. The data looks ok to me at first glance…

You could try reloading the entire asbuilt for the APIM and then Master Reset. I’ll research some, I have heard of this and I thought there was a solution.

You did not mention if you are using CarPlay, but there have been issues reported with this in CP and the GPS lock will not return until an ignition cycle.
