They’re already are, see above.
Here’s the AB from a 2018 F150 XL with the 302A package that came with NAV & XM,
2018 F150 XL NAV.ab (33.4 KB)
Ended up getting it to work, added wire from apim to acm (27-5).
Changed navigation splitter harness to gl3t-10a397-cb with a male to male adapter (correct PN OOS). End result, HD radio, cd, bluetooth, usb inputs, wifi, XM(280 channels) - no center channel.
That means you have an X40 even though it has a JL3T part number on it.
You can try to use AB explorer and look at the deltas between what you have in the ACM/APIM vs the AB I posted from a 2018XL that can from the factory with XM & NAV.
Its working, good enough for me. All settings are for pre x40.
