Pocket Casts supports CarPlay! If you’re getting a shiny new car, or stereo for your old rust bucket, rest assured you can plug in and go. When you do you’ll be able to browse your podcasts and filters for an episode to play as well as control playback all without touching your phone.
Once you have formed the new URL, you can add it to Pocket Casts by pasting it in here: https://pocketcasts.com/submit. Please ensure you select Private so it will never appear in search results and other places. It’s just for you. You can use the short URL you get back to quickly add it to the app.
If this does not work for your feed, contact the podcast author.
