On my 2015 F150 XL, I successfully swapped my 4.2 Sync 1 for 8 inch Sync 3 w/Nav and also added an OEM rear camera. All work perfectly thanks to the many people here that post their builds and help others with theirs. Also have to include everyone that has done so much work on and with Forscan. The issue I am having is with a newer ACM module that I want to install. My original has AM/FM, CD and Sirius and works fine. But, I would like to have HD radio and I see that the 2019 ACM's with Sirius actually now have SiriusXM. For those that don't know, there is a difference. SiriusXM is the newer radio with more channels. I purchased a 2019 ACM, two actually but that is another story, from a 2019 F150. It has SiriusXM and HD radio. I installed it in my F150 and nothing. The Sync 3 comes on, Nav works, just no audio. The screen says "Audio Off". I thought that the module may be dead so I removed it and installed the second one that I had purchased and got the same result. So, I connected Forscan and it could not see the ACM. I know there are different CAN buses and the ODBII cable I have is the ODBLink EX that auto switches between the buses. I put my original ACM back in and all is fine. I am wondering if Ford changed any pins on the connectors on the back of the ACM with the new 2019 model. I have been searching and coming up with nothing that matches my situation. I do have access to the pinouts for my 2015 ACM but not for the 2019 so I can't verify if anything is different. So, if anyone has any ideas, I would greatly appreciate your help!

 

Does anyone have any ideas?

 

I think that all changed in 19 go to forscan forun and do a search there and you should find some info on that

I’ve could swear I’ve seen mentions about the latest acm’s being significantly different than earlier ones....like in a software/configuration/way it interacts with everything else sorta way and not just + sxm and - CD player sorta thing. I don’t remember exactly what or if it was overcame via different as built settings though as it was something that didn’t interest or concern me, but I do recall seeing this on here before though.

 

any luck I just got a 2019 ACM from a fusion ti and no sound ether, I want HD radio

 

So, the 2019 vehicles have two extra wires between the ACM and the APIM, and to make them work in an earlier vehicle, you need to add those two wires, and use an APIM and ACM from a 2019 . . . the ACM you need only comes in Lariats with the 502A package and higher trim levels, where the B&O Sub is installed . . .

I could be wrong, but I'm pretty sure that some of the earlier models had HD Radio along with Sirius XM . . . you could use an ACM from one of those vehicles and not have to change anything else out or add any wires . . .

 

I got both from the same car, do you know where to find a wiring diagram?
thanks
