Connect your iPhone to CarPlay and tap Castria on the car's screen. The CarPlay app is part of Castria Premium and needs iOS 26.4 or later.
The car shows four tabs:
- Listen Now: episodes to keep listening to, and new episodes.
- Up Next: your queue.
- Playlists: your playlists. Tap Play all or Shuffle.
- Shows: your subscriptions. Tap Play latest, or Add all new to Up Next.
The Now Playing screen has buttons for speed, the sleep timer, topics, marking an episode played, and saving it. Ad skipping works in the car just as it does on your phone.
If Castria says:
- Update to iOS 26.4 or later: update your iPhone.
- Sign in to Castria on your iPhone: open Castria on the phone and sign in.
- CarPlay is part of Castria Premium: subscribe in Castria on your iPhone. The car unlocks straight away, without reconnecting.
You add shows and queue episodes on your iPhone. The car is for playing.
