The combo of PMS50 mod for GNS530 and my mod for KAP140 (both on github) seem to work as before. I have not found any recent new issues (yet) with that combo. If present the PMS50 mod will be used in C310R emulation in place of the WT GNS530W mod in the marketplace.
In todays release post, Milviz is recommending this combo of 3 mods:
https://github.com/pimarc/pms50-gns530/releases/download/v1.0.54/pms50-gns530.zip
https://pms50.com/fs2020/gtn750/pms50-gtn750.zip
https://pms50.com/fs2020/gtn750/aircrafts/pms50-gtn750wtt-aircraft-milviz-cessna310.zip
which does indeed include a new KAP. You can use gns530 in panel and the gtn750 will run in the background.
The PMS50 KAP code is recently updated and I have not had time to test fully yet.
The WTT ‘stuff’ is more advanced emulation of the GPS with many improvements including in approach processing. Note: you need to use the ARM button with the WTT KAP to capture an altitude.
