Wireless CarPlay Adapter

User Manual

Important Instructions

This wireless CarPlay adapter is designed to work exclusively with iPhones and is incompatible with other smartphones or tablets.
This wireless CarPlay adapter is designed exclusively for cars that already have their own wired CarPlay function and does not support cars without CarPlay functionality.
Only iPhone 6 and later models are compatible with this wireless CarPlay adapter. Please note that your iPhone operating system must be iOS 10 or higher to use this adapter.
If your car has been customized with some wireless features (such as Wi-Fi dash cam, car 360 surround monitoring, etc.), the car screen may appear black after the connection is completed. This is not a defective issue of the product. In such cases, it is recommended to contact the customer service team for assistance.
To avoid signal conflicts, ensure that there are no existing Bluetooth or Wi-Fi connections on your current phone before connecting the wireless CarPlay adapter.
The adapter can only be connected to one device at a time. If there are multiple iPhones present, please ensure that only the user's iPhone is connected to the Bluetooth and Wi-Fi signal of the adapter "smartBox-xxxx".
After the initial setup, the wireless CarPlay adapter will automatically reconnect to the previously paired device on subsequent uses (ensure your phone's Wi-Fi and Bluetooth are enabled before use). In some vehicles, you may need to manually disconnect the other Wi-Fi to maintain wireless CarPlay use.

How to Use

Working Mechanism: The wireless CarPlay Adapter uses Bluetooth to set up the connection between the phone and the vehicle and then switches to using Wi-Fi for the actual functionality. After the Bluetooth pairing is successful, the phone's Wi-Fi will be occupied by the wireless CarPlay program, while disconnecting the Bluetooth connection. If you switch the Wi-Fi connection to other devices or turn off the Wi-Fi of the phone, the wireless CarPlay will disconnect. It is recommended to keep only the connection with the adapter in your phone's Bluetooth and Wi-Fi lists.

Setup Steps:

Start the car and wait for the infotainment system to boot up fully. Turn on the Wi-Fi and Bluetooth of your phone and make sure they are not connected to any external networks or devices.
Plug the wireless CarPlay adapter into the USB or USB-C port designated for Apple CarPlay in your vehicle. If your car has multiple ports, ensure you connect the adapter to the port assigned for wired CarPlay (typically identified by a white wire frame around the port or a specific icon next to it).
After connecting to the correct port, the indicator light will illuminate. Your vehicle's display will then switch to the interface shown below, indicating it is ready to pair.
Go to the phone's Bluetooth setting, and select "smartBox-xxxx" to pair. If the initial pairing attempt is unsuccessful, please try a few more times.
After Bluetooth pairing, your phone's Wi-Fi will automatically connect to the wireless CarPlay adapter's Wi-Fi signal "smartBox-xxxx". During this period, do not manually connect to this or any other Wi-Fi signals.
Once the car display transitions to the CarPlay control interface, this indicates that the connection has been successfully established.

LED Light Description:

Cyan status: Power on indicator.
Green status: CarPlay connected (green light is always on).

To Ensure Wireless CarPlay Works Smoothly:

Settings > WLAN > Ask to Join Networks > select "Notify".
Settings > WLAN > Click the 'i' symbol on the far right of "smartBox-xxxx" > Turn on 'Auto Join'.
In some cars, you need to select "automatic connection" in the CarPlay settings so that the automatic connection function of the adapter can be used.

Online Firmware Upgrade

Premise:

When the wireless CarPlay adapter functions correctly, the current version is compatible with your car. In such cases, it is advisable not to update the firmware to prevent potential issues.
Only attempt to update when your problem cannot be resolved using the solutions provided in the FAQ list.
If issues arise after the upgrade, consider resetting the factory settings or returning to the previous version.

Update Steps:

Power up the wireless CarPlay adapter.
Connect to the wireless CarPlay adapter's Wi-Fi network with the password "88888888".
Open Safari and enter "192.168.1.101", scroll to the bottom of the page, then select the latest version in the drop-down box and click "Update".
After the upgrade, please restart your phone once before using the wireless CarPlay adapter.

Note: The adapter's Wi-Fi itself does not have the Internet function. You need to turn on the cellular network of your phone to enter the upgrade website.

FAQ

1. What is the password to connect to Wi-Fi?

Normally, what we need to manually connect is Bluetooth, not Wi-Fi. After the Bluetooth connection is successful, the Wi-Fi will be automatically connected, and no password is required. The password is set up for upgrading the firmware. If the adapter functions correctly, it is advisable not to update the firmware to prevent potential issues. When pairing, only initiate a Bluetooth connection, no need to manually connect to Wi-Fi, and make sure Wi-Fi is enabled and not in use.

2. The indicator light of the wireless CarPlay adapter is still on after the car is turned off.

Some cars will not immediately cut off all power when they are turned off, so the adapter light won't go off immediately either. If the car will always keep some power even when it's off, you can unplug the adapter when you get out of the car, so that you don't have to worry about the car battery. No operation is needed, or unplug the adapter when the car is not in use.

3. Can't find the Bluetooth or Wi-Fi signal "smartBox-xxxx" of the wireless CarPlay adapter?

Possible Causes: 1) The smartphone's Wi-Fi and Bluetooth modules are malfunctioning. 2) The wireless CarPlay adapter is defective. Solution: If convenient, you can test it with another iPhone. If only a specific iPhone cannot find the Bluetooth or Wi-Fi network and Bluetooth settings of this iPhone and then restart the phone once (this will require you to re-enter the password when connecting to Wi-Fi networks that you have connected to before). If the same problem happens on other iPhones, the unit may be defective. In this case, please let us know and we will refund you or send you a replacement. Reset network settings (this will cause you to re-enter your password when using a network you have previously connected to): Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Clear the pairing record, restart the phone, and re-pair the adapter.

4. Audio input or output issues: calls rejected or forwarded to voicemail/no play sound/microphone not working/music playback interrupted or paused/voice functioning abnormally...

Possible Causes: Bluetooth plays a pivotal role in the pairing and audio transfer functionality of the wireless CarPlay adapter. Audio issues may arise if the phone's Bluetooth is connected to multiple devices, with the background device of the mobile phone occupying the Bluetooth connection or if the audio output selection is incorrect. Solution: 1) Please check your phone's Bluetooth to see if it is connected to another device. If so, please ignore other auto-connected Bluetooth devices or turn off the Bluetooth directly (such as your car/watch/Airpods). Settings > Bluetooth > Choose the Bluetooth that comes with the car like "Car model xxxx" > Click the exclamation mark: select "Forget This Device". 2) Clear the programs running in the background of your phone when using the wireless CarPlay adapter. 3) When on a call, check that your "Audio" output option is CarPlay. Persistent disconnection? Possible Causes: Dropped connections are usually caused by Wi-Fi interference. Solution: 1) The wireless CarPlay adapter relies on a Wi-Fi connection to work. Dropped connections are usually caused by Wi-Fi interference. Do you have other Wi-Fi devices in your car, such as a car camera with a Wi-Fi function? If so, you may need to ignore other Wi-Fi networks when using the wireless CarPlay adapter. 2) You can also improve this problem by resetting your mobile WLAN network. Also, updating the firmware of your wireless CarPlay adapter is worth trying. 3) Other cases: A. Please make sure that the Bluetooth and Wi-Fi functions of your mobile phone are turned on and the Bluetooth is not occupied when you get in the car; B. Clear the pairing record, restart the phone, and re-pair the adapter. C. Try to upgrade the firmware (refer to page 6).

5. Persistent disconnection?

Possible Causes: Dropped connections are usually caused by Wi-Fi interference. Solution: 1) The wireless CarPlay adapter relies on a Wi-Fi connection to work. Dropped connections are usually caused by Wi-Fi interference. Do you have other Wi-Fi devices in your car, such as a car camera with a Wi-Fi function? If so, you may need to ignore other Wi-Fi networks when using the wireless CarPlay adapter. 2) You can also improve this problem by resetting your mobile WLAN network. Also, updating the firmware of your wireless CarPlay adapter is worth trying. 3) Other cases: A. Please make sure that the Bluetooth and Wi-Fi functions of your mobile phone are turned on and the Bluetooth is not occupied when you get in the car; B. Clear the pairing record, restart the phone, and re-pair the adapter. C. Try to upgrade the firmware (refer to page 6).

6. The wireless CarPlay adapter won't pair with multiple phones? Why does pairing fail when using different mobile phones?

Possible Causes: Pairing occupied. Solution: The adapter can be paired with multiple iPhones, but it can't connect with them at the same time. In addition, the system will connect back to the last used iPhone due to the default function of Bluetooth. Therefore, before pairing to a new iPhone, please disconnect the Wi-Fi and Bluetooth of the currently connected iPhone and manually set up the connection in your new iPhone.

7. Unable to automatically reconnect?

Possible Causes: Phone/car screen settings problem. Solution: 1) In some cars, you need to select "automatic connection" in the CarPlay settings so that the automatic connection function of the adapter can be used. 2) Check phone settings: A. Settings > WLAN > Ask to Join Networks: select "Notify"; B. Settings > WLAN > Click the "i" symbol on the far right of "smartBox-xxxx" > turn on "Auto-Join".

8. When the phone plays videos, why the audio is not synchronized with the video?

Possible Causes: Problems with wireless CarPlay systems. Solution: Even the original wireless CarPlay that comes with the car also has an audio delay when watching the video. This is due to video transcoding is a more complex process than normal audio file transcoding and takes longer to process. To minimize delays, we have used a dual-module design to improve product transmission speed. However, this is a normal problem of wireless CarPlay, not the adapter's problem.

9. Car screen goes black/CarPlay no response after pairing?

Possible Causes: Wi-Fi does not connect automatically. Solution: 1) When you pair it for the first time, you need to keep the Wi-Fi turned on (no need to manually connect to the wireless CarPlay adapter's Wi-Fi at this time), and then perform Bluetooth pairing. When the Bluetooth pairing is successful, the Wi-Fi will automatically become connected to the adapter. You can check whether your Wi-Fi has automatically changed to the state of connecting the adapter when the black screen appears. If not, please unplug the wireless CarPlay adapter - ignore the "smartBox-xxxx" on your Bluetooth list - restart your phone once - plug the adapter and repair it again. 2) Make sure that your phone's Bluetooth and Wi-Fi are active and NOT connected to other devices (such as your car/watch/Airpods). 3) If it still doesn't work, please try to update the firmware and reset the adapter. A. Refer to page 6 to upgrade the firmware; B. Unplug the adapter - Clear the established Bluetooth pairing in your phone with the adapter (unpair the "smartBox-xxxx" in the Bluetooth list and delete it) - Open your phone system settings, general, CarPlay, select "smartBox-xxxx", and forget this car - Restart your phone - Reconnect and pair as you did the first time.

10. Audio lag or sound quality problem (excluding audio delay during video playback)?

Possible Causes: The audio stream mode has a frequency conflict with the vehicle system. Solution: Enter the upgrade page and modify "Audio stream mode" (please refer to pages 6-7 of the manual).

11. When pairing, CarPlay does not start or the car prompts that the device is not compatible/does not recognize the USB.

Possible Causes: Different cars have different interface protocols. Solution: Enter the upgrade page and modify the "Start-up delay" setting (please refer to pages 6-7 of the manual).
