I just swapped a non-Nav Sync 3 Screen and APIM(starts with K) into my 2014 F150 that had Sync 2. The APIM initially had version 3.3.18266 and when I would go to sources and press SiriusXM, it would make a sound but nothing happens.
I have since updated to 3.4.22251 and done a Master Reset and am still having the same issue. Everything else seems to work(AM, FM, Bluetooth, HVAC, heated/cooled seats/etc.)
Any ideas? My 7D0-01-01 is set as Axxx xxxx xx
Oh and I did turn on Sirius Travel Link in the APIM and I can go in and see my Sirius Radio ESN. So it does know its there and sees the correct ESN.
