Frequently Asked Questions

The app says Music access is turned off

Digital CD Changer needs Music Library permission to show your albums. If access was denied previously, open the Settings app, find Digital CD Changer, enable Media & Apple Music access, then reopen the app.

My albums are not appearing

Make sure the albums are available in your Apple Music library or purchased music library on this device. If you recently changed your library, close and reopen the app so it can refresh. Library availability may also depend on your Apple Music subscription status, sync state, and whether the music is still available through Apple.

CarPlay is not showing the app or looks out of date

Confirm that CarPlay is enabled for your iPhone and vehicle or receiver, then disconnect and reconnect CarPlay. If the interface still seems stale, reopen the app on iPhone and try again. CarPlay templates are controlled by Apple, so final appearance and availability can vary by system version and hardware.

Playback will not start

Check that the selected album or track is still available in your library and that Apple Music playback works normally on the device. If playback was interrupted by another audio app or system event, try again after returning to Digital CD Changer.

A slot shows an unavailable album

This usually means a previously assigned album can no longer be resolved from your current music library. Remove or replace that slot with an album that is currently available on this device.

I reached the magazine or disc limit

The free tier includes one magazine with up to six disc slots. To add more magazines or more slots per magazine, upgrade to Pro from the ••• menu (Pro Mode). Pro is a one-time in-app purchase with no subscription.

How do I upgrade to Pro?

On the main changer screen, tap •••, choose Pro Mode, and follow the prompts to complete the one-time purchase through Apple. After purchase, you can create unlimited magazines and use unlimited disc slots per magazine.

I already bought Pro but it is not unlocked

Open ••• → Pro Mode and use Restore Purchases. Make sure you are signed into the same Apple ID used for the original purchase. If restore does not work, check your App Store purchase history for the Pro upgrade, then contact Apple Support for billing issues or email us with your device and iOS version.

Purchases, Billing, and Refunds

Digital CD Changer is free to download. The optional Pro upgrade is a one-time in-app purchase sold through the Apple App Store—not a subscription. Apple handles billing, purchase history, restore, and refunds. For charges, refund requests, or purchase problems, use Apple Support and your App Store purchase history. For restore or unlock issues after confirming your Apple ID purchase, email mitchell525@gmail.com.
