I upgraded to SYNC3 and Ive had some interesting issues. First the volume would be maxxed out all the time but someone here helped me modify the ACM so thats fine. I installed some new speakers and in trying to fade them in the controls I noticed those functions wont stay adjusted. Fade/Balance go to front left although the speaker are all playing equally and the EQ just resets to max after you adjust. Anybody have any idea? The APIM and ACD were from a Sony system and that was the original issue with the volume. I will attach current asbuilts for APIM and ACM.
Normally the place to start with the ACM when the donor has the Sony and you don’t is to use your factory AB to overwrite the values in the ACM so it matches your car or to get the AB from an SE.
What’s the part number of the ACM?
There nothing really “special” about the internals of the Sony ACM on the older ACMs, you just pic up an HD radio tuner IC in the US (off & on for this is controlled by the setting in the APIM). Newer units use an A2B for the Sony / B&O.
Would have to pull dash apart to get part number. The apim acm and hvac module all came out of a 2017 taurus limited.
What does ForScan show for the part number/assembly number?
I will look into it. Did not know forscan gave you that information. Do you know what area shows that?
You’ll see that in the log page as it finds modules
eg
