Hi @Stephenie , welcome to the Pandora community!
I'm sorry for the trouble you are experiencing.
All Pandora automotive implementations require you to use a compatible iPhone or Android with an active internet connection in order to stream music in the car.
In other words, if you are using an iPhone you need to use CarPlay to connect and if you have an Android device you need to use Android Auto.
In your case, since you changed from an iPhone a Samsung Galaxy phone (Android), now instead of using the CarPlay app on your car you need to use the Android Auto app. Unfortunately Android Auto is not compatible with iPhone and CarPlay is not compatible with any Android phone.
Hope this helps!
