The car phone works fine if someone calls me or if I manually dial out.
Does anyone know why I am unable to sync adresses between device and auto?

It seems to basically involve downloading an app and having a high enough OS version (which you do). It seems like an old article and I haven't tried it myself, but hopefully it helps.
