I never inputted my VIN anywhere and eveyrthing still works. Is that important? What does it do?
No idea but am wondering if that was the reason my Forscan profile load showed so many DTC’s. I have been running with this incorrect VIN for months and never noticed anything weird. Got back into Forscan to increase the bass and volume of my stock 6 speaker radio and just started looking in all the drop down modules out of curiosity. Saw the VIN for the first time in BdCM and corrected it. Then saw it again in at least 2 other modules but it was correct in them. Will be driving it tomorrow for the first time since making several changes, hoping nothing goofy happens.

Ugh so test drive results are... no steering wheel radio control buttons work (including phone) except up and down volume. Dammit! Also, when the car is shut off, the screen goes blank but won’t shut off for a long time. Thought I had it figured out but guess not.

Has any 2020 owner upgraded to sync3? I don't seem to be able to fix hazard toggle switch. The 726-29 line in the Bodycm as built is different. There is no 02 line.
I downloaded a premium 2020 as built and they match what I have for 726-29.
Also lost FordPass connection, but that's a different topic. Any help is appreciated.

Loaded the APIM.abt backup file and everything works now, so the problem was in there somewhere.

Anyone know what I need to mess with in forscan to get radio working correctly?

I bought an plug and play harness but guessing I need some stuff tweaked in forscan because only my right speakers work with the Bluetooth audio and I gotta changed audio format using the audio request button but I don’t hear the lady either

FYI I have a 2016 PP1 and went from the sync 1 to sync 2

Hi. Will a sync 3 manufactured in 2019 work in a 2016 mustang? Is there any differences between the different years they were manufactured? I’d just prefer to get the newest one possible. Cheers
