after retrofitting snyc 3 into a 2015 Taurus I recently tried updating my sync 3 apim and sadly bricked it, the replacement APIM worked with Siri after I changed some ACM asbuilt bits (AC is original to the car)
Siri works perfectly (ex, reading my messages as well as voice commands) I noticed though Waze doesn’t talk (aside from muting my music) even though I tried playing with the volume. I thought it might be a Waze issue but I noticed when reading out my Whatsapp messages sync will immediately skip the whole message and ask do I want to reply?
I’ve googled the Whatsapp issues but haven’t found anything, I tested Waze with Android auto and had the same experience.
