Carlinkit 4.0 Design

The Carlinkit 4.0 adapter is made from lightweight and durable Carbon Fiber, which is stylish and environmentally friendly. Its eye-catching blue color and excellent finish make it a perfect accessory for any car. Moreover, the device is fingerprint-resistant and scratch-resistant. You’ll find the Carlinkit branding on the front and an LED indicator placed just below it. You’ll find the device’s serial number and regulatory markings on the rear.

Carlinkit 4.0 Wireless Apple CarPlay / Android Auto Adapter

The device has two USB ports – USB-A on the top and USB-C on the bottom. The USB-A port can only be used to upgrade the device’s firmware using a PC or Laptop. The USB-C port connects your car. You’ll not find any buttons on the device. If your car has a USB-C port, use the supplied USB-C to USB-C cable. If your car has a USB-A port, use the supplied USB-C to USB-A cable.

Carlinkit 4.0 Setup

Before we begin the setup, there’s one more important aspect to consider: the USB cable. It’s crucial to use the cable that comes bundled with the device or invest in high-quality cables from trusted original equipment manufacturers (OEMs). Google recommends using a cable under 3 feet (1 meter) in length. It’s essential to avoid using USB hubs or cable extensions.

Alternatively, you can also try using the USB cable that originally came with your phone. The bundled cables are typically 30cm long, providing ample length to keep the device conveniently positioned near the USB port or infotainment system. Now that we have the cable aspect covered let’s proceed with the setup process.

Carlinkit 4.0 Connection

Both Android Auto and Apple CarPlay apps are built into the operating system. CarPlay updates are automatic and get updated automatically whenever there is an Apple system update. Google pushes frequent updates to Android Auto via Play Store, and you need to update it manually. If you are using Android Auto, make sure the app is updated to the latest version. Check this link to update the app via Google Play Store.

You don’t have to worry about enabling additional options in Android Auto Settings because the Android Auto app detects whether your car supports Wired or Wireless Android Auto. Update the Android Auto app, and you’re all set to start using it without any further configurations required.

To begin, connect the Carlinkit 4.0 adapter to the USB port in your car that supports Android Auto/CarPlay. If your car has multiple USB ports, ensure that you connect the adapter to the specific USB port that is enabled for Android Auto or CarPlay functionality. In the below image, note that the USB port on the left is designated for Android Auto / Apple CarPlay, while the USB port on the right is intended for charging purposes. Follow the below steps to pair the adapter with your car.

Apple CarPlay / Android Auto Port
  • Once you connect the device to the USB port, the LED light on the front starts blinking Red, and at the same time, the Bluetooth name is displayed on the car screen, making it easy to identify and connect to the appropriate device.
  • Turn on Bluetooth and Wi-Fi on your phone.

After tapping on the Pair option, the adapter promptly establishes a wireless link between your phone and the infotainment system. With that, the setup is finished, and you can now utilize Android Auto / Apple CarPlay wirelessly in your vehicle.

The Carlinkit 4.0 Adapter is a versatile 2-in-1 adapter that enables you to wirelessly connect both your Android and iPhone to your car’s infotainment system. The adapter is compact, has excellent build quality, and is made up of scratch-resistant material. I have been using the Carlinkit 4.0 adapter in my MG Astor for over two weeks and am thoroughly satisfied with its performance. It operates seamlessly, requiring no manual intervention.

Using the touchscreen to navigate the interface on wireless connections feels as seamless as using a wired connection. I have tested the adapter with Google Pixel 7A, OnePlus Nord, OnePus Nord 2T, and iPhone 14 Pro, and I haven’t encountered any latency or touch response problems whatsoever. As soon as I start my car, within 20 seconds, the music starts playing from my favorite music app, Google Maps seamlessly appears on my screen, ready for navigation without any need to touch the screen or retrieve my phone from my pocket to connect it.

The audio quality is good, and the voice calls are fast and clear as well. I’ve tested multiple apps like Google Maps, Spotify, Apple Music, YouTube Music, and JioSaavn and have not experienced any issues. I was also able to interact with Google Assistant and Siri without encountering any difficulties. The steering wheel controls also work fine, and I could change the tracks and increase/decrease the volume without any issues.

Despite the absence of a dedicated app, accessing the device settings on the adapter is very easy. Moreover, the company has also provided multiple options to fine-tune the device settings, allowing users to address any potential compatibility concerns with specific infotainment systems. The major downside I noticed pertains to seamless switching. When using both an Android and an iPhone, it is not possible to seamlessly switch between the two devices.

Instead, you must disconnect the Android device before connecting the iPhone to the adapter. Also, the adapter has to be replugged to bring up the boot menu. During my testing, I couldn’t use the dial pad on the screen as it didn’t respond to any inputs. It appears to be a bug that is expected to be fixed in future updates. It is crucial to note that utilizing Android Auto wirelessly can significantly drain your device’s battery life faster than anticipated. So for long drives, wired connectivity is recommended.

The Carlinkit 4.0 adapter delivers exactly what it promises and is undoubtedly a compelling option to consider. If you are seeking a device that supports both Wireless Android Auto and Apple CarPlay, the Carlinkit 4.0 stands out as one of the top choices under $100 / INR 8,000.

  • Scratch-resistant
