I have had my ct for about 2 months now it’s a none nav car and turn the Bluetooth up all the way up to 4 whatever that means but i still can’t hear who I’m talking to that well, i half to turn my a/c off to hear them i never had this problem with other Lexus so i don’t think is just me being hard of hearing or anything ;-) just want to know if any one besides me has had this issue. and if so what did they do to fix it
