In some vehicles, the built-in OEM GPS antenna may provide better performance under satellite signal obstruction (such as in urban canyons or covered areas).

Important Notes:
● Not all vehicles with wired CarPlay or Android Auto are equipped with an independent OEM GPS module or support external GPS data output.

● If your vehicle does not support OEM GPS positioning data, enabling this setting will have no effect.

4.4 Wi-Fi Hotspot Compatibility Mode

If you want the CB4PL to stay connected to an external Wi-Fi network while using CarPlay or Android Auto, enable this option.

With the CB4PL's dual-band Wi-Fi (2.4 GHz / 5 GHz), this mode allows Android apps on the CB4PL to continue accessing the internet without affecting the CarPlay or Android Auto connection.

⚠ Enabling this mode will reduce system performance, causing navigation lag, audio stutter, or unstable CarPlay / Android Auto connections.

For smoother operation, do not enable this mode.

Chapter 7 Troubleshooting

Important Note:

1.  If you have checked the points described in this chapter and the problem persists, unplug the CB4PL for 10 seconds and then plug it back in.

2.  If the problem still occurs after following the suggestions, please contact Customer Service for further assistance.

1. General Issues

Issue 1: CB4PL does not respond / does not power on / restarts randomly

Reason & Solution:

● Confirm wired CarPlay / Android Auto support

Make sure your original car head unit actually supports wired CarPlay or wired Android Auto.

CB4PL cannot work with systems that support wireless CarPlay / Android Auto only.

● Check the correct USB port

Ensure the CB4PL is connected to the original USB port specifically used for wired CarPlay / Android Auto.

Some vehicles have multiple USB ports, but only one supports CarPlay/Android Auto data transmission.

● Verify vehicle compatibility

Confirm that your car model is compatible with CB4PL.

● Check cable connections

Ensure all cables are securely connected.

● Insufficient USB power supply

For vehicles with weak USB power output (e.g., certain Nissan, Isuzu, Toyota, Lexus, and Volkswagen models), use the included Y-shaped power cable and connect it to a cigarette lighter socket or a high-power USB port.

● Possible power cable issue

If the CB4PL still does not power on, the supplied power cable may be defective.

Please contact your dealer or ATOTO official customer support to request a replacement cable.

Issue 2：Original car head unit cannot recognize CB4PL system even when properly connected and powered

Reason & Solution

●Incorrect connection mode:

Ensure CB4PL is in the correct mode (CarPlay or Android Auto) according to your head unit. (See 2.4.2 for details)

●Compatibility limitation:

Certain car models or head units may not fully support external Android system overlay. Check CB4PL compatibility list.

●Aftermarket head unit compatibility:

Certain aftermarket head units may experience protocol incompatibility or unstable connections. If this occurs, please contact ATOTO Customer Support for further assistance.

●Try “Link” app again:

Tap the “Link” or similar app on the original head unit to manually access CB4PL.

●Restart devices:

Power off CB4PL and original head unit for 10 seconds, then reconnect.

Issue 3: CB4PL loses power after being used for a while

Reason & Solution:

●Insufficient or unstable power supply: For stable operation, the CB4 requires a stable 5V / 1A power supply. If necessary, please use the provided Y-shaped power cable to ensure adequate and stable power.

●Overheating due to poor ventilation. Avoid placing CB4PL in enclosed spaces like glove boxes or armrests.

Issue 4: CB4PL disconnects and restarts when releasing the brake pedal at a stoplight

Reason:

●Vehicles with a Start-Stop system automatically turn off the engine at temporary stops. When the engine restarts, the battery may experience a brief voltage drop, causing CB4PL to reset.

Solution:

●Confirm whether your vehicle has a Start-Stop system.

●If yes, try disabling the Start-Stop system.

●If the problem is resolved, check whether the Start-Stop function can be permanently or manually turned off.

2. Network & Internet Issues

Issues1: CB4PL cannot connect to Wi-Fi

Reason & Solution：

Wrong password, out of range, interference: Verify Wi-Fi SSID and password. Move closer to router or hotspot.

Issues2: Mobile data not working

Reason & Solution：

SIM not activated, unsupported carrier, PIN locked: Use activated data-only SIM. Check LTE band compatibility. Disable SIM PIN. Verify carrier supports CB4PL IMEI.

3. Bluetooth Issues

Issues1: Bluetooth fails to pair

Reason & Solution：

●CB4PL or phone may already be connected to another device: Disconnect the current Bluetooth connection before pairing again.

●Device not in range or not discoverable: Enable Bluetooth on both CB4PL and phone. Ensure device is discoverable and within range.

Issues2: Bluetooth screen lock not working

Reason & Solution：

Device not paired or out of range: Ensure phone is paired with CB4PL. Enable Bluetooth unlocking in BT Lock app.

4. CarPlay / Android Auto Connection Issues

Issue1：Wireless CarPlay/Android Auto cannot connect

Reason & Solution：

Bluetooth or Wi-Fi not enabled, device not compatible: Enable Bluetooth and Wi-Fi on both phone and CB4PL. Ensure phone is not connected to other networks. Pair through CB4_xxxx device in Bluetooth.

Issue2：LED indicator flashes slowly

Reason & Solution：

Unable to connect to CarPlay / Android Auto: Check phone compatibility (iOS 9+ for CarPlay; Android 11+ for Android Auto; older devices may have limited support). Reboot CB4PL and retry connection

5. GPS & Location Issues

Issue1: GPS signal weak or slow

Reason & Solution:

●CB4PL GPS obstructed:

Place CB4PL near car air vent for better reception.

● Vehicle GPS not enabled:

If GPS positioning remains slow or unstable, the CB4PL can use the vehicle’s original GPS antenna (if supported by your head unit), which usually provides stronger and more stable signals.

Please contact ATOTO Customer Support for detailed guidance on enabling or configuring this option.

Issue2: Location-based apps not functioning

Reason & Solution：

GPS disabled or app permissions not granted: Enable Location in Settings > More > Location > Use location. Grant location permission to apps.

6. TF Card Issues

Issue: Cannot play media files

Reason & Solution:

● Unsupported file format. Supported video formats: TS, 3G2, AVI, MKV, WEBM, MPG, MOV, 3GP. Supported audio formats: MP3, OGG, FLAC. Convert the file if necessary.

● Unsupported file system. Replace the TF card with one formatted in a supported file system.

7. 4G SIM (EIOTCLUB) Issues

Important Note (Service Disclaimer)

The included EIOTCLUB SIM card and its data plans are provided and managed by EIOTCLUB as a third-party service.

If you encounter activation, plan, payment, or service quality issues, please contact the SIM service provider for support.

Issue 1: No mobile network / no signal icon after inserting the SIM

Possible Causes：

● SIM card is not activated, or the trial package has expired.

● SIM card inserted in the wrong orientation / not fully seated.

● Local carrier coverage is weak in the current area.

Solution：

● Confirm the SIM is activated (scan the QR code / follow the activation guide), and check plan status in the EIOTCLUB app/service page.

● Power off the device, reinsert the SIM correctly, then reboot.

● Move to an area with better LTE coverage and retry.

Issue 2: SIM works on a phone but not on the CB4PL / keeps prompting or fails to connect

Possible Causes：

● SIM has PIN lock enabled (CB4PL does not support entering SIM PIN).

● SIM is data-restricted by the provider (IoT plan policy / APN provisioning / region restriction).

Solution：

● Insert the SIM into a phone, disable SIM PIN, then move the SIM back to the CB4PL and reboot.

● Confirm the plan supports data usage on IoT devices in your region. If unsure, contact the SIM provider.

Issue 3: Data is very slow / unstable connection / frequent dropouts

Possible Causes：

● Network congestion or weak LTE signal.

● Trial package throttling or plan limit reached.

● Device installed in a location with poor reception (enclosed spaces).

Solution：

● Relocate the box for better reception (avoid glove box/armrest; place closer to open area).

● Check remaining data / speed policy in the EIOTCLUB service page or app.

● If stability is critical, use Wi-Fi or a reliable hotspot as an alternative.
