Help Hands Free Incoming Calls

I have recently noticed that whenever I receive calls on my hands free car radio (Sony 410), it now only displays the number and not the contact name. I have a Galaxy A12 phone and yes, I have checked that my contact listing has synced to my radio. I don't recall having altered any settings and nothing I try will restore it from this state. Has this happened to anyone else and if so, how did you fix it?
