There are two wireless interfaces to the stereo.

The advantage of playing thru the stereo is you get better sound quality and can use the outdoor speakers.

1. Bluetooth pairing to the BT-B27 bluetooth receiver. (see below)
Works with most mobile devices.
  - Works to redirect all sound from your mobile device (most are bluetooth enabled).
  - Requires bluetooth pairing first.

2. A chromecast audio interface (see below)
  - Works only with chromecast enabled apps, such as Pandora, Slacker Radio, Spotify, Google Play, iHeartRadio, ...
  which have casting built in.
  - Uses wi-fi for a little better audio   - Wi-fi works over a greater distance.

(Apple Music is protected by Digital Rights Management (DRM) and can't be played on other devices without some third party apps to remove DRM.)
Amazon Music only suports casting on android devices, Samsung, Huawei, LG, Motorola Moto, Google Pixel, ....

Here's a schematic of the connections for you techies.

Both are connected to the Video/Aux input to the stereo. <
