Hey guys. New here. Just bought a 2017 Dodge Journey Crossroad the other day. I have been playing around with all the bells and whistles and I noticed something in the settings of my Uconnect. Under accessibility it has "Read back main cabin". I have checked and unchecked it and have no clue what it does. Does anyone else know? I can't find any info on it online or in the manual. BTW it is the 8.4 Uconnect system without navigation. Thanks.
