User Manual: 2-in-1 Wireless Adapter (HVIN: C3020A, U2, U3)

HOW TO USE

Setup Step

Start the car and wait for the car head unit system to be loaded.
Connect the 2-in-1 Wireless Adapter to your vehicle's USB or USB C port. Note if your car has several ports, please be sure to plug the dongle into the port that is for wired Apple CarPlay or Android Auto.
Turn on your Phone's WiFi, then the adapter "SmarBox-XXXX" will appear in the list. Please do not connect to it or to any other WiFi list at this time, just keep Wi-Fi on and not be occupied.
Turn on the Bluetooth, search for the adapter 'SmarBox-XXXX', then click it to pair. After a few seconds, the phone will prompt "Use Carplay", click the prompt and wait for 5-15 seconds to connect successfully.
After the first pairing, the 2-in-1 Wireless Adapter will automatically reconnect to your iPhone when you use it again (please make sure the phone's WiFi and Bluetooth are turned on). In some cars, you may need to choose the option of "Start automatically" in the CarPlay settings to activate this function.

FAQ & TROUBLESHOOTING

1. What is the password to connect to WiFi?

What we need to connect is Bluetooth, not WiFi. No password is required for connecting to Bluetooth. Make sure your WiFi is turned on and unoccupied when pairing.

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

Because the car will not cut off all the power immediately when it is turned off, the light of the adapter will not go out immediately, but it will take a while. Please rest assured that its power consumption is minimal and will not drain the car battery.

3. Can't find the Bluetooth or WiFi of the adapter?

If convenient, you can test it with another Phone. If only a specific Phone cannot find the Bluetooth or WiFi of the adapter, please try to reset the network and Bluetooth settings of this Phone and then restart the phone once. If the same problem happens on other Phones, the unit may be defective. In this case, please let us know and we will refund you or send you a replacement.

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

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.
Clear the programs running in the background of your phone when using the adapter.
When on a call, check that your "Audio" output option is CarPlay or Android Auto.

* Note: Bluetooth plays a pairing role in the work of the adapter. When the pairing is completed, it only needs wifi to keep working, so it doesn't matter to turn off Bluetooth. But when you use it next time, you still need to turn on Bluetooth, so that the adapter can be automatically paired and connected.

5. Persistent disconnection?

The adapter relies on a WiFi connection to your phone to work. Dropped connections are usually caused by WiFi interference. Do you have other WiFi devices in your car, such as a car camera with a WiFi function? If so, you may need to ignore other WiFi networks when using the adapter.
You can also improve this problem by resetting your mobile WLAN network. Also, updating the firmware of your adapter is worth trying. 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.

6. Can the adapter be paired with multiplephones?

The adapter can be paired with multiple iPhones, but only one device can be connected at a time. If you would like to pair it with a new Phone, please cancel the current connection first. Please note, by Bluetooth function default, the adapter's system will only auto-connect back to the last used Phone.

7. Unable to automatically reconnect?

In some cars, we need to select "automatic connection" in the CarPlay or Android Auto settings so that the automatic connection function of the adapter can be used.
Check phone settings:
1. Settings > WLAN > Ask to Join Networks: select "Notify";
2. Settings > WLAN > Click the "i" symbol on the far right of "SmartBox-xxxx" > Turn on"Auto-Join".
Other cases:
1. Please make sure that the Bluetooth and WiFi functions of your mobile phone are turned on and the Bluetooth is not occupied when you get in the car;
2. Clear the pairing record, restart the phone and re-pair the adapter.
3. Try to upgrade the firmware.

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

Even the original wireless CarPlay or Android Auto that comes with the car also has an audio delay when watching the video. Because video transcoding is more complex than normal audio file transcoding and takes longer to process. This is a normal problem of wireless CarPlay or Android Auto, not the adapter's problem.

9. Car screen goes black after pairing?

When we pair it for the first time, we need to keep the wifi turned on (no need to manually connect to the adapter's wifi at this time), and then perform Bluetooth pairing. When the Bluetooth pairing is successful, the wifi will automatically become connected to the adapter. You can observe whether your wifi has automatically changed to the state of connecting the adapter when this page appears. If not, please unplug the adapter - ignore the"SmartBox-xxxx" on your Bluetooth list - restart your phone once - plug the adapter and repair it again.
If it still doesn't work, please try to upgrade the firmware.

ONLINE FIRMWARE UPGRADE

Premise

If the adapter works properly, it means the current version is suitable for your car. It is not recommended to update the firmware in this case to avoid any problems.

Enter the IP address "192.168.1.101" in your phone's web browser.
Click "Update" on the OTA page. (Do not exit the page during the upgrade process to avoid interrupting it.)
Once the upgrade is complete the page will display "Update Completed."
Unplug and replug the adapter
Delete the old Bluetooth connection on your phone and establish a new Bluetooth connection to start using the upgraded product

*If the update fails, please try the following:

Turn off your phone's Bluetooth;
