Somewhere in 2026 the internet decided that a custom CarPlay startup sound is called an “intro” — the clip that plays through your car speakers the moment your iPhone connects. Tesla-style chime, movie sound bite, three notes of your favorite track. Same feature, new name. Here is how to add one, start to finish, on iOS 26.
TL;DR — the 30-second answer
Apple doesn't offer a built-in intro setting. To add an intro to Apple CarPlay you need one of two things: a dedicated app like Car Play Connect (pick a sound, it plays on every connect), or a free Shortcuts automation (works, but fires inconsistently since iOS 26.0). The sound itself should be an .m4a or MP3 under three seconds.
What counts as a CarPlay intro
The intro is any audio that plays right after the CarPlay handshake completes — after the two-tone system chime, before your music resumes. Because it plays through the car's speakers at whatever volume the head unit is set to, short and tonal beats long and loud. The clips that survive daily use are under 1.5 seconds; anything longer collides with the first seconds of your music.
Step 1: Pick the intro sound
Grab a ready-made file or trim your own. Export as .m4a (MP3 works too), keep it under three seconds, and normalize the loudness so it doesn't blast at highway volume.

Step 2: Load it into a startup-sound app
In Car Play Connect: open the Sounds tab, choose one of the 46 built-in packs or tap Import to bring in your own file. The app stores the clip locally, so it works without a network connection in a parking garage.
Step 3: Set the trigger to CarPlay connect
Toggle the startup sound on and grant the one-time permission prompt. From then on the intro fires on every CarPlay connection — wired or wireless. You can set a separate disconnect sound too, which is the underrated half of the feature: an audible confirmation that the phone actually released the car before you walk away.
Step 4: Test it with the engine running
Volume behaves differently between accessory mode and a running engine on many head units. Plug in, let CarPlay load, listen. If the intro is too loud relative to your music, trim the source file's gain rather than the car volume — the car setting also changes your navigation prompts.
The free Shortcuts route (and its limits)
Shortcuts → Automation → When CarPlay Connects → Play Sound. It costs nothing and works most days. The catch: since iOS 26.0 the CarPlay trigger fires inconsistently when the phone connects while locked — which is most real-world connects. Our full field guide to both methods documents the failure pattern and the exact Shortcuts recipe if you want to try it first.
FAQ
Can I use a song as my CarPlay intro?
Yes, but trim it. Export the three seconds you want as .m4a and import that clip. Pointing an automation at a full track means the intro runs into your actual music and you end up hearing the same opening twice.
Why doesn't my CarPlay intro play every time?
If you built it with Shortcuts, that's the known iOS 26 trigger inconsistency — it fires unreliably when the iPhone is locked at connect time. A dedicated app hooks the connection event directly and doesn't depend on the automation engine.
Does the intro work on wireless CarPlay?
Yes. The trigger is the CarPlay session starting, not the cable. On wireless the intro plays a second or two later than wired because the session itself takes longer to negotiate.
