after upgrade I had trouble with audio, volume wouldn't be as loud as before, bluetooth audio messed up with calls. Got it solved with these values.

try this ACM values:


727-01-01 920x xxxx xxx
727-01-02 x300 xx
Thank for the info but unfortunately there is no way to alter those values as in the Fiesta (at least) the configuration is not by AsBuilt for the ACM but by Central Configuration. The CC/IPC forces the radio to use a smaller format asbuilt (1 byte) without the options available. I have not been able to get it to report the extended format in any way.

I figured out my problem: Bad connections

The APIM plug pins are about .2mm thinner than my measurement tool's pins which caused them to extend too far and make no or bad connections. Fixed this and the sound from the 'alert'/mono line is back again.

Settings are now which work:
112 - In car entertainment High level CD AM/FM
154 – Accessory USB without
157 – bluetooth Handsfree without or G2 bluetooth (makes no difference)
172 – Front Display DM8 with nav
214 – Mini ICP (08)

I changed the ACM value byte to 02 but this seems to make no difference but it was that on the car from which the Sync 3 device came from so I kept it like that.
