New CarPlay Features in iOS 18.4: More Icons, Smarter Routes
- Big screens just got an extra row of icons for lightning-fast access.
- A smoother, less distracting ride is now on the horizon.
- Apple Maps now plays nice with Tesla Superchargers for EVs.
- Wonder how these tweaks could change your drive? Read on!
Apple’s latest iOS update isn’t just about pretty new features—it’s also giving CarPlay a subtle but thoughtful refresh. With iOS 18.4 now available in beta and slated for a broader release in early April (according to Apple’s website), the changes might seem minor at first glance, but they pack a punch for those with the right vehicles.
A New Layout
One of the standout adjustments in iOS 18.4 is the revamped CarPlay interface. As reported by MacRumors, certain cars now benefit from an extra row of app icons. Instead of the usual two rows, select models—like the Toyota Tundra equipped with a 14‑inch display—show three rows, allowing drivers quicker access to a broader range of apps. This means less time swiping between pages and a reduced chance of distractions while driving.

However, this upgrade isn’t universal. Smaller screens, such as those in a Honda Civic with a 9‑inch display or an 8‑inch panel seen in some vehicles, continue to show the traditional two-row setup. For drivers of larger-screen models, this extra row is a welcome enhancement, ensuring the interface makes full use of the available space without inflating icons to impractical sizes.
EV Routing
Another notable update comes from Apple Maps. iOS 18.4 now supports electric vehicle routing that incorporates the North American Charging System (NACS)—the standard that includes Tesla Superchargers. This enhancement links your EV’s battery level with Apple Maps’ navigation, automatically inserting charging stops at the optimal points along your route.
At present, the feature is somewhat limited. It appears compatible with a handful of models on the market—specifically Ford’s F‑150 Lightning and Mustang Mach‑E. As Ford explains, this capability is already available on CarPlay for iPhones running iOS 17 or later, meaning no additional software update is necessary. Here’s how Ford advises drivers to set it up:
- Connect your iPhone to CarPlay.
- Open Apple Maps, navigate to Settings, and select your preferred charging network—ensure you choose a NACS fast charging station like a Tesla Supercharger. (You only need to do this once.)
- Enter your destination.
- Apple Maps will calculate your battery’s state of charge upon arrival.
- If a charge is needed, the app will automatically reroute you to a NACS fast charging station.
When a route is started that includes Tesla Superchargers, drivers may see a warning that the route requires a Fast Charging Adapter (NACS) – drivers should make sure to have it with them to use.
Looking Ahead
While these updates might seem modest compared to the long-rumored next-generation CarPlay—which promises a complete overhaul of in-car software—there’s no denying their immediate impact. For tech enthusiasts and Apple fans alike, these refinements demonstrate Apple’s commitment to improving the user experience incrementally, ensuring that both the driving experience and EV navigation become smoother and more intuitive.
It’s always exciting to see how even small tweaks can make a big difference on the road. If you’re fortunate enough to have a vehicle with a larger infotainment screen or an EV that supports NACS, iOS 18.4 might just be the upgrade that makes your drive a little smarter and a lot safer.
