How to Install CarPlay Themes on iPhone

Out of the box, every CarPlay screen looks the same. A theme changes that: coordinated wallpaper, widget colors, icon styles and layout that turn the default grid into something that actually matches your car — or your mood.

What a CarPlay theme can change

Apple doesn’t offer full theming natively, but iOS 26 opened enough doors to make real theming possible:

• Wallpaper — CarPlay supports a set of wallpapers natively in Settings, and iOS 26 widened the options.
• Widgets — fully customizable through third-party widget apps like CarTheme: colors, backgrounds, fonts, icon styles.
• Layout — which widgets appear, in what order, in what stacks.
• Sound — a startup sound that completes the identity.

A theme in CarTheme is all of these bundled into one preset you apply in a tap.

Installing a theme with CarTheme

1. Download CarTheme and open the Themes tab.
2. Browse the gallery — minimal dark, retro digital, pink aesthetic, BMW-style, JDM and more.
3. Tap a theme to preview how the widgets and colors look together.
4. Tap Apply Theme. The app generates the themed widgets and walks you through adding them to CarPlay (Settings → General → CarPlay → your car → Widgets).
5. Optionally attach the theme’s matching startup sound on the same screen.

Setting the CarPlay wallpaper

The wallpaper itself is set on the phone:

1. Open Settings → General → CarPlay and choose your car.
2. Tap Wallpaper and pick one of the available options.
3. For a coordinated look, pick the wallpaper closest to your theme’s base color — CarTheme’s theme pages tell you which one pairs best.

Making your own theme

The gallery is the fast path, but the editor is where CarTheme shines. Start from any preset, then:

• Change the accent color to match your interior lighting.
• Swap icon styles between filled, outlined and glass.
• Adjust widget backgrounds — solid, gradient or transparent.
• Save it as your own theme and reuse it across CarPlay and your iPhone home screen.

Troubleshooting

The theme applied but CarPlay looks the same. Themes work through widgets — make sure you completed the Add Widget step in Settings after applying.

Colors look washed out in the car. Many head units run brighter/cooler than an iPhone screen. Try the theme’s high-contrast variant, designed for washed-out displays.

Can I have different themes for different cars? Yes — widget layouts are per-vehicle in iOS 26, so your daily driver and weekend car can run different setups.
