Ardupilot / here4 X7+/ cuav

Good afternoon

I’m currently using a CUAV X7+ pro FC in a ALIGN T-REX 800e pro DFC traditional helicopter.
Is there anybody out there who uses this FC ( cuav ) together with the HERE4 GPS/compass system ?
I would be interested if there are any known problems with calibrating in MP and as well if there are
CAN protocol problems known ?

Thanks a lot
Kind Regards
