I replaced the radio in my RV a couple of months ago with an Alpine Stereo that has Apple Car Play. If you have a iPhone you plug it in to the radio and can use various iPhone apps on the stereo. The main one I like is the GPS function so you get an inscreen GPS unit. But you can also use iHeart radio and play music directly from your iPhone. And not only that but the unit also has AM/FM and the capability to do satellite radio it you want it, but I didn't hook mine up for that.
