The NEXTECH LA9038 Vehicle Tracker includes the following components:

ON/OFF Switch

LED Indicator

SIM Card Socket

GPS Antenna

Standard Wire Harness

The LED indicators on the NEXTECH LA9038 have the following meanings:

GREEN LED Flash once: 2G/3G/4G & GPS working well

GREEN LED Flash twice: 2G/3G/4G working well and no GPS signal

GREEN LED Flash three times: 2G/3G/4G & GPS working well but battery low

GREEN LED Flash four times: 2G/3G/4G working well, battery low and no GPS signal

GREEN LED ON continuously: 2G/3G/4G searching network

GREEN LED OFF continuously: Power off

RED LED Flash once: uploading current tracking

RED LED Flash twice: can not upload tracking now

Open the SIM card room cover with your finger and slide the switch to the ON position. The tracker will then power on. If the tracker’s battery is low, connect the power & GND wire to the car battery. After power on, the LED will flash. If the Green LED flashes once every 4 seconds, it indicates the tracker is working well.

The NEXTECH LA9038 uses a 2G/3G/4G Micro SIM card. To install, open the SIM card room cover. Slide the metal cover to the “OPEN” direction to open the SIM card holder. Insert the SIM card into the holder, paying attention to its direction. Then, press and slide the metal cover to the “LOCK” direction to secure the SIM card.

The NEXTECH LA9038 uses a 2G/3G/4G network and uploads tracking data only through the internet. Ensure the SIM card data service is enabled (some SIM cards may require an SMS or USSD command to enable GPRS). Ordering a data package (20-30MB/month) can help save data charges, as most trackers typically use less than 20MB per month. Always power off the tracker before installing or uninstalling the SIM card.

The NEXTECH LA9038 requires a 9-40V DC power supply and should be continuously connected to the car battery. The wiring connections are:

RED or BROWN wire: Connect to 12V/24V car battery

BLACK wire: Connect to GND (Car Body)

WHITE wire: Connect to ON Signal (Engine Running) Positive Input

The ON signal indicates if the engine is running (positive means engine is running). If the ON signal is positive, the NEXTECH LA9038 will begin uploading location to the server. If the ON signal is open, it will stop uploading. If the GREEN wire is not connected to the ON signal, uploading is controlled by the shock sensor: when the car starts moving, the tracker uploads location; after the car stops moving for 2 minutes, it stops uploading.

To use the YELLOW wire for engine cut, a relay must be added. When the NEXTECH LA9038 receives an engine cut command, the YELLOW wire will continuously output a negative signal. This signal drives the relay to control the engine’s power supply or petrol pump power supply, turning off the car engine. The output current of the YELLOW wire is less than 500mA, and a diode must be added to protect the tracker’s driving wire. A 12V relay is needed for a 12V car, and a 24V relay for a 24V car. Normally, the engine cut output controls the car’s starting motor, oil pump motor line, or ON wires. Be aware that turning off the engine while the car is driving is dangerous.

For car security, the NEXTECH LA9038 should be installed in a hidden place, such as behind the seat, inside the armrest box, under the back window, or within the panel. It is crucial that the installation location allows the tracker to receive 2G/3G/4G and GPS signals. The GPS antenna side must face the sky to receive GPS signals. Before replacing any cover panels, confirm that the tracker can locate its position after installation. If the location is inaccurate or lost frequently, try changing the installation spot.

Most SIM cards require APN and user name & password settings for internet access. To set the APN, send the SMS command “APN*12345678*apnname” to the tracker, where “12345678” is the device password and “apnname” is the SIM card data service APN name. The device will reply “APN: apnname”. To set the internet user name and password, send the SMS command “USERNAME*12345678*username*password”, where “username” is the internet visiting account name and “password” is the account password. The device will reply “USERNAME: username, PASSWORD: password”. If the SIM card is an M2M card without SMS service, you may need to insert a normal SIM card first to configure these settings, then switch back to the M2M card.

When the NEXTECH LA9038’s power supply is off or the voltage is too low, the tracker will send a power down alarm SMS to the authorized number. This indicates that the tracker’s power has been removed or the tracker itself has been removed.

To reset the NEXTECH LA9038 to factory settings (like a new tracker) via SMS, send the command “FACTORY*12345678”. “FACTORY” is the command, and “12345678” is the tracker password.

The working temperature for the NEXTECH LA9038 is -20°C to 60°C. Outside this range, the specifications may not reach the standard level. The storage temperature can range from -40°C to 80°C.

The initial preparations required are:

1. First, you will need a functioning 2G GSM or 3G WCDMA or 4G LTE mobile phone SIM card with a data plan for internet usage.

2. Connect the tracker power wire to the car battery and slide the switch to the ON position. The Green LED will be on continuously, indicating the tracker is powered on. Place the tracker outdoors to easily get GPS & mobile phone network signal.

3. Check the LED flash, referring to the System LED Indicator for details. If the Green LED flashes once, it means mobile phone and GPS signal are well. If the Red LED flashes once, it means the location has been uploaded to the server.

4. The NEXTECH LA9038 can auto-configure APN & GPRS user name & password. If the auto-configuration is incorrect, the tracker will not visit the internet, and its location will not update on the app & website. The red LED will flash twice. In this case, you need to send an SMS to the tracker to manually change the APN & GPRS. Send “CHECK*12345678” to the tracker to check the APN auto-configuration. Call the tracker’s SIM card supplier to confirm the correct APN & GPRS. Send “APN*12345678*apnname” and “USERNAME*12345678*username*password” to the tracker to change the APN & GPRS setting.

5. Visit and log in to the tracking platform. Select the language, and you can check the current location, playback history tracking, etc. The platform user name and password are the last 7 digital numbers of the tracker’s ID (e.g., if ID is 803201712345678, the user name is 2345678, password is 2345678 or 123456). Users can change the password by sending “ID*12345678” to the tracker to check its ID.

6. The App also uses the same user name and password as the website login. Visit the website with a mobile phone, click the app icon on the login page, or scan the QR code on the login page to download and install the iPhone & Android app.

To set the GPRS mode, send one of the following SMS commands to the NEXTECH LA9038:

For KEEPONLINE mode (always online, even when the tracker stops moving): “KEEPONLINE*12345678”

For SHOCKCONTROLGPRS mode (turn off GPRS 10 minutes after the tracker stops moving): “SHOCKCONTROLGPRS*12345678”

“KEEPONLINE” or “SHOCKCONTROLGPRS” is the command, and “12345678” is the tracker password. If successful, the tracker will send back “GPRS: Keep Online” or “GPRS: Shock Control”. If the password is incorrect, the operation will fail, and the tracker will send back “Wrong Password”. The default setting is Shock Control. In Shock Control mode, the tracker uploads tracking when it moves and goes to sleep (GPS off, GPRS online) and offline (GPS & GPRS off) a few minutes after stopping. Keep Online mode uses more data and car battery power and is not recommended for long parking or old car batteries.

To remotely reset the NEXTECH LA9038, send the SMS command “RESET*12345678” to the tracker. “RESET” is the fixed command, and “12345678” is the password. If successful, the tracker will send back “Cancel all alarm setting and re-power on”, then it will power off and on automatically. If the password is incorrect, the operation will fail, and the tracker will send back “Wrong Password”. This command can be used if the tracker is not working properly.

There are two methods to reset the NEXTECH LA9038 to factory settings:

Method 1 (SMS): Send the SMS command “FACTORY*12345678” to the tracker. “FACTORY” is the fixed command, and “12345678” is the password. If successful, the tracker will send back “Setting back to factory default”, delete all user settings, and restore all settings to factory mode. The tracker will then power on again after deleting user settings.

Method 2 (SOS button): First, switch the tracker’s power switch to OFF. Then, press and hold the SOS button. Do not release it. After a few seconds, the LED will flash, and then a few seconds later, the LED will turn OFF. Now, release the SOS button. Finally, switch the power switch to ON again. All tracker settings will have been reset to factory mode.

If you have changed settings like APN, IP, or authorized numbers, you will need to reconfigure them after a factory reset. If the password used for the reset is incorrect, the operation will fail, and the tracker will send back “Wrong Password”.

Important notes for operating the NEXTECH LA9038 are:

1. Please confirm that the SIM card PIN code has been disabled. If a mobile phone uses this SIM card, it should not require any password. Otherwise, the tracker cannot find the GSM or CDMA network, and the Green LED will remain ON.

2. This tracker uses 2G GSM & 3G WCDMA networks and uploads tracking only through the internet. It cannot work in CDMA or CDMA2000 networks. If a 4G SIM card can operate on 2G GSM or 3G WCDMA networks, then it can be used in this tracker.

3. The GSM and GPS antennas are built into the tracker. Ensure the installation location allows the tracker to receive a GPS signal. Keep the tracker away from large metal objects and magnetic components.

4. GPS typically needs 10-200 seconds to locate its position. If the GSM signal is weak or the network is busy, SMS messages may be delayed by the GSM network; this is normal.

5. Tracking data on our server will be kept for 3-6 months; older data will be deleted.

If the NEXTECH LA9038’s RED LED flashes twice and the location cannot be updated, it indicates that the SIM card data service is not enabled, or the APN and username/password for internet access are not set correctly. You should confirm these settings.

The NEXTECH LA9038 uses 2G/3G/4G networks and uploads tracking only through the internet. It is not compatible with CDMA or CDMA2000 networks.

The GPS antenna is built into the NEXTECH LA9038. It’s important that the installation location allows the tracker to receive a GPS signal. Typically, locations like the back of the seat, door post, roof post, under the back window, or under the panel can work. Ensure the tracker is kept away from large metal objects and magnetic components, and that the top of the GPS antenna faces the sky.

The NEXTECH LA9038 has a built-in rechargeable backup Li battery. A single full charge can provide power for about half an hour. Normally, the tracker should always be connected to the car battery to ensure continuous power. The charging circuit will stop automatically once the battery is full.

The GPS on the NEXTECH LA9038 typically needs 10-200 seconds to locate its position. If the GSM signal is weak or the network is very busy, SMS messages may be delayed when sent via the GSM network; this is considered normal behavior.

The tracking data from the NEXTECH LA9038 on the server will be kept for 6-12 months. After this period, the old data will be deleted.

If the NEXTECH LA9038 auto powers off, please confirm that the tracker’s power supply is properly connected to the car battery and that the power fuse is in good condition.

If the NEXTECH LA9038’s GREEN LED stays on, but there is no response or ringing, you should confirm the following:

1. The SIM card has been installed properly.

2. The SIM card PIN code is disabled.

3. The SIM card has enough credit/charge.

4. The mobile phone network works well in that location.

If the tracker is working correctly, the Green LED should flash once or three times every 4 seconds (note: initial power-on or recharging the battery may delay the first locating by 5-30 minutes).

If the NEXTECH LA9038 cannot upload location to the website, confirm the following:

1. The SIM card has GPRS function enabled.

2. The APN or GPRS username & password is correct. You can send the SMS command “CHECK*12345678” to check the auto-configuration, and call the mobile phone hotline to confirm the correct APN & GPRS.

If the tracker is not moving, it will not upload tracking. Try moving the tracker in an open air environment (indoor rooms cannot receive GPS signal).

If the NEXTECH LA9038 cannot send back information by SMS, confirm the following:

1. The SIM card has enough money/credit.

2. The SIM card has caller ID display function and SMS service function enabled.

3. Read the SMS information that the tracker sends back to check if the instruction and password are correct.

If the NEXTECH LA9038 rings when called but does not hang up, check if an authorized phone number has been set. Use an authorized phone number, delete the authorized phone number, or reset the tracker to factory settings.

After leaving an underground parking area, the GSM and GPS modules of the NEXTECH LA9038 will take a few minutes to receive signals and re-locate. During this time, some tracking data may be lost, which is normal.
