Mavic Radar Red Arrow Error and Fix?

[vas67]

Mavic Pro Radar red arrow shows different positions depending on phone orientation or cable choice.
It seems the external USB Is correct or is it opposite phone orientation??
Any thoughts please??

which direction is the RADAR map point pointing towards?
please see above thread where I go over many types of calibration and cord location problems that cause the red arrow to wander.
