I swapped my 2014 F150 4” MFT to Sync 3 3.4 Build 21265. I am having issues where my phone audio will not play over bluetooth or usb (carplay). The carplay does work and I can see my phone on the screen. Also my steering wheel volume works, but not the skip forward or backwards button. Also Forscan is recognizing it as a sync 1.1 and not letting me program all the 8 blocks on the APIM, I can only see the first 4.
I have been reading that after sync 3.0 they dropped support for the older architectures (C1MCA or CGEA 1.2).
I already tried changing the code in the ACM that supposedly fixes the audio issues but no luck. I can hear AM/FM and the radio touch “beeps/boops” over my speakers.
Is it possible to downgrade from 3.4 to 3.0?
Or do I need to find an older APIM? Also do I need to swap my ACM from something newer like a 2016 explorer?
