Attention all Apple iPhone users. If you have a base model audio system that is installed in the RT and RTL do not download the new iOS 11.2. Your bluetooth streaming will not work with your audio system. I downloaded it this morning and on my morning drive to work I could not play my Sirius Radio app thru my audio system unless I connected thru the iPod port in the center console. If anyone else has experienced this same problem and has a fix please respond.
