Motorola EX124G from Tracfone bluetooth issues

Has anyone else had this issue and resolved it? My Motorola EX124G from tracfone mostly works with my Prius IV Navigation system. I can do most everything with it, except that it won't allow me to answer calls.

I had an older Motorola tracfone that would let you hear the ring and answer through the Nav system. With this phone, the phone itself will ring but you won't hear anything on the car speakers. I'm unable to answer by pressing the off-hook button on the steering wheel or by trying to anwer the call manually on the phone itself.

I can dial through the Nav system just fine, transfer contacts, etc., just can't receive a phone call.

Please Help!
