User Def Waypoints duplicated in FF FP Upload

New IFD550 User here running v10.2.6.1 and experimenting transferring flight plans from FF on my Ipad.

I operate from a private airstrip with no official ICAO designation, which I have set up manually as a UDWP in both FF and IFD FMS/WP, taking care to make sure the format and coordinates are exactly the same in both systems.  Let us call my UDWP VTSW.

When I transfer a FP from FF to the IFD containing UDWP VTSW, rather than match up the two UDWP's  - the IFD (I assume) - manufactures a new UDWP called FF001 with the exact same coordinates and uses that in the imported route.

If I transfer another FP from FF containing UDWP VTSW the new route references FF001 so it is matching the coordinates the second time around with its own automatically created UDWP.  Any future imports containing VTSW all end up as FF001 in the IFD imported route.

I then tried deleting my manually entered UDWP VTSW and editing UDWP FF001 name to VTSW, but stubbornly the next FP came in generating a new FF001.

Any suggestions where I am going wrong gratefully received!

Thanks - Eduardo

I am not sure the UDWP has to also be in the Jepp database. Given the behavior I have described, some form of matching is going on otherwise I would expect to see a new UDWP created inside the IFD every time FF sent one. I think that hidden away is an attribute or setting when a UDWP is created via a FP transfer as opposed to manually from inside the box.

I guess when I edit that manufactured UDWP the setting is lost and subsequent matching logic fails.

Out of interest what long/lat format is your FF and IFD set to?.
