How to Add Apple CarPlay to Any Car
Apple CarPlay can be added to almost any car in three ways: replace the factory stereo with a CarPlay head unit, fit a plug-in CarPlay interface behind the factory screen, or use the manufacturer’s own retrofit or activation where one exists. Which route fits your car depends on the dash opening and the screen it came with.
Many modern vehicles come equipped with Apple CarPlay, allowing drivers to seamlessly connect their iPhones to their car’s infotainment system. But what if your car doesn’t have CarPlay built in? Fortunately, there are several ways to retrofit an older vehicle with CarPlay, improving both convenience and safety while driving.
This guide will cover:
- What Apple CarPlay is and why it’s useful
- Different methods to install CarPlay in a car
- Key considerations for CarPlay installation and compatibility
- The benefits of upgrading your car with CarPlay
What Is Apple CarPlay?
Apple CarPlay is a system that integrates an iPhone with a car’s infotainment display, allowing drivers to control their phone via the touchscreen, steering wheel buttons, or voice commands. Instead of fumbling with a phone while driving, users can access navigation, music, messaging, and other apps directly through the car’s interface.
Main Features of Apple CarPlay:
- Navigation: Apple Maps, Google Maps, and Waze with real-time traffic updates
- Music & Audio: Apple Music, Spotify, and podcast apps
- Communication: Hands-free calls and messaging through Siri
- Apps: Access to compatible apps like WhatsApp, Zoom, and Audiobooks
- Voice Control: Siri for hands-free operation
Even if your car did not come with CarPlay, it is possible to install it using aftermarket head units, CarPlay interface modules, or OEM retrofit solutions.
Ways to Install Apple CarPlay in Your Car
1. Replacing the Factory Head Unit (Aftermarket Car Stereo)
One of the most common ways to add CarPlay to an older vehicle is by replacing the existing stereo system with an aftermarket head unit.
Which Car Stereo Systems Support CarPlay?
Many well-known brands offer multimedia systems with built-in CarPlay support, including the Android head units we stock for specific models in our shop, supplied with the matching fascia and plug-in harness, plus:
- Pioneer – Premium-quality displays and sound systems
- Kenwood – Reliable units with Apple CarPlay and Android Auto support
- Alpine – High-end multimedia systems with excellent audio quality
- Sony – Affordable and stylish touchscreen displays
How to Choose the Right Head Unit?
- Check the size of the dashboard opening:
- Single-DIN: Standard 50mm (2 inches) high stereo slots
- Double-DIN: Larger 100mm (4 inches) high units with a bigger touchscreen
- Consider additional features:
- HD touchscreen
- Bluetooth and Wi-Fi connectivity
- Rear camera input
- Built-in GPS navigation
Pros of Replacing the Stereo System:
- Full CarPlay support with a high-quality touchscreen
- Improved sound quality and additional features
- Compatibility with backup cameras and sensors
This is the route for cars with a basic radio and no screen; see our car radio installation page and a typical example, this VW Polo Android head unit.
2. Using a CarPlay Interface (Plug & Play Solution)
If replacing the entire stereo system is not an option, a CarPlay interface can be a practical alternative.
What Is a CarPlay Interface?
A CarPlay interface is an adapter that connects to the existing infotainment system, enabling CarPlay functionality without requiring a full stereo replacement.
How It Works:
- Installed behind the factory radio
- Connects via Bluetooth, Wi-Fi, or USB
- Controlled through the original touchscreen, steering wheel buttons, or voice commands
Advantages of a CarPlay Interface:
- Keeps the original car design intact
- Easier installation compared to a full stereo replacement
- Cost-effective solution
- Supports both Apple CarPlay and Android Auto
Before purchasing, check if your car’s infotainment system is compatible with a CarPlay interface module. We fit these behind factory screens on Audi, BMW, Mercedes, Porsche, Land Rover, Jaguar, Lexus and Volvo, for example this Audi Q5 wireless CarPlay box; the service page is Apple CarPlay & Android Auto.
3. OEM Upgrade from the Manufacturer
Some automakers offer official software or hardware upgrades to add Apple CarPlay to older models.
How to Check if an Upgrade Is Available?
- Contact an authorized dealership
- Check the manufacturer’s website
- Look for third-party upgrade services specializing in OEM software updates
Potential Downsides of OEM Upgrades:
- Can be expensive, often costing between €500 and €1,500
- Not all car models support this upgrade
- Requires dealership installation
If an official CarPlay upgrade is not available for your car, a CarPlay interface module is usually the best alternative. Where the car already has the hardware but the feature was never switched on, which is common on 2017+ Audi, BMW and Skoda models, Apple CarPlay activation enables the factory feature without adding any hardware.
Cost of Adding Apple CarPlay to a Car
The price of upgrading your car with CarPlay varies depending on the method you choose:
- Aftermarket head unit: €250 – €1,000
- CarPlay interface module: €150 – €500
- OEM software/hardware upgrade: €500 – €1,500
Our own prices are on each product page in the shop, with professional fitting in Dublin added at checkout.
Installation Tips and Considerations
1. Professional Installation vs. DIY
While some CarPlay solutions can be installed without technical expertise, others require wiring modifications and dashboard disassembly. If unsure, professional installation is recommended to ensure compatibility and prevent damage. Send your registration and a photo of the dash and we will confirm the right route and a fitting slot at our Dublin 11 workshop: get a quote.
2. Update the Firmware
After installation, make sure the new system’s firmware is updated to the latest version. This will ensure the best performance and compatibility with your iPhone.
3. Test All Features
Before finishing the installation, test CarPlay connectivity, navigation apps, call functions, and audio playback to confirm everything is working correctly.
Why Upgrade Your Car with Apple CarPlay?
- Safety: Reduces distractions by allowing hands-free control of your phone
- Convenience: Easy access to navigation, music, and calls while driving
- Up-to-Date Navigation: Use real-time traffic apps like Google Maps or Waze
- Voice Control: Control key functions using Siri
- Enhanced Driving Experience: Better infotainment system with modern features
Upgrading your car with CarPlay transforms your driving experience by making it more connected, intuitive, and safe. Whether you choose to replace the head unit, install a CarPlay interface, or opt for an OEM upgrade, there are options to suit every budget and preference.
