I CANNOT MAKE CALLS ON MY HANDS FREE BECUSE THERE IS A PROBLEM WITH THE TCU. NISSAN IS AWARE OF THIS IMPORTANT SAFETY ISSUE AND THEY WANT THOUSANDS TO FIX IT. I CANNOT USE MY HANDS FREE IN MY TRUCK, I CAN HEAR THE VOICE OF OTHERS BUT THEY CANNOT HEAR ME. ITS A HUGE DISTRACTION WHEN MAKING AND RECEIVING CALLS. THIS TCU IS CAUSING THE MIC NOT TO WORK. NISSAN HAS A TECHNICAL BULLETIN ON THIS. IT IS UNDER CLASSIFICATION: EL18-006 AND REFERENCE: NTB18-023=NISSAN; MICROPHONE DOES NOT WORK
