Sorry for the confusion. Some newer automobiles now come equipped with radio systems that can either work with a smartphone or in some cases the radios use the smartphone OS like Android or iOS. These are slowly improving. My Toyota RAV4, for example, not only automatically connects to my iPhone via BT when I start the vehicle, thus allowing calls to be made and answered via the radio system in a hands free manner, but it also makes my iPhone music available to the car radio to play. Other automobiles have much more sophisticated systems that will allow you to run iOS or Android apps on the radios. I'm using the term "radio" but what these systems are is much more than just radios. They tend to include GPS navigation, backup camera displays, etc. They are basically like having a small Android tablet or iPad built into the automobile's dash, but have radio listening capabilities too. Some systems, like the one in my RAV4, just tap into my iPhone data to exchange information and work like a remote speaker/controller for the phone and music. More sophisticated models can play the apps too. At present, most of these systems are still not very good, but they are getting better.
