JCarTools first-time setup: a complete guide to the main features

Before you start

Complete the JCarTools installation and grant the required permissions. Configure vehicle-related features only while parked, with the infotainment system switched on and the power supply stable.

1. Make sure JCarTools opens without a licence error.
2. Install and open the navigation or other apps you want to display on the instrument cluster.
3. Change one setting at a time and check the result immediately. This makes it much easier to identify the option responsible for any unexpected behaviour.

If JCarTools is not installed yet, begin with the JCarTools installation guide. A separate USB GPS guide is also available.

1. Select the correct vehicle profile

The selected profile determines which features JCarTools displays and which commands it can send to the vehicle. In “Vehicle profile”, always choose the entry intended for your exact make and model.

Check whether your vehicle has a profile

The list of supported profiles continues to grow. The names below help you identify the relevant vehicle family, but available features may differ even between cars of the same make.

2. Open an app on the instrument cluster

Use this section to choose an app for the digital instrument cluster, such as Yandex Maps, Waze or another compatible navigation app.

1. Select Yandex Maps, Waze or another installed app.
2. Use the manual instrument-cluster launch first. Check that the app opens and that you can return to the factory interface.
3. If required, test the app on the tablet or centre display as well.
4. Enable automatic launch only after the manual test succeeds.
5. Test full-screen mode separately because it may cover factory information on some system versions.

The custom cluster settings are located nearby. They control the JCarTools instrument-cluster layout and, on supported profiles, the automatic launch of the custom gauges.

3. Custom projection

This section configures additional information prepared by JCarTools. On EXLANTIX vehicles, the data is shown on the head-up display. On other supported vehicles, it is shown on the instrument cluster, not on the head-up display. Open “Configure”, choose the information you need, check it on the appropriate screen and only then enable custom projection.

Depending on the profile, the configuration may include navigation details, speed-camera events, the current speed limit and the placement of guidance prompts. Availability also depends on the navigation app and the display method supported by the vehicle.

4. Automatically start an app on the head unit

Autostart can open navigation or a media player, or run a prepared task group when the vehicle starts.

1. Select the required app.
2. Open it manually and complete any first-run sign-in, confirmation or update.
3. Enable “Automatically launch the app on the head unit when the vehicle starts”.
4. Use the black-screen option only after testing its separate configuration.
5. If you need several actions, create a task group and set their order.

5. Overlay widgets

JCarTools can show a clock, outside temperature, free storage, music controls, weather and VPN status over the factory interface. The available widgets depend on the app version and selected profile.

• Over system elements allows widgets to appear above factory panels. Use it only when important controls remain visible.
• Size and position lets you move and resize widgets. Enable movement while arranging a widget, then disable it to prevent accidental changes. You can restore a widget to its normal size with the size control.
• Weather can use the built-in source or a supported external app.
• VPN shows connection status and opens its separate configuration.
• Clock, temperature, storage and music are enabled and configured individually.

6. Apps, permissions and system tools

The tools section contains APK installation and removal, permission management, JCTStore, a file manager and app hiding. These tools modify software on the head unit, so use files from sources you trust.

• Install / uninstall / grant permissions manages apps and their access rights.
• JCTStore provides a catalogue of prepared apps.
• File manager lets you work with files stored on the head unit.
• Hide apps removes selected apps from the visible factory list without necessarily uninstalling them.

Other settings may include hiding the factory voice-assistant hologram, sharing map location, replacing GPS coordinates and configuring edge swipes. Test gestures while parked because they may conflict with factory system gestures.

7. Vehicle settings

After you select the correct make and model, JCarTools shows “Vehicle settings” only when the profile includes at least one supported function. The contents vary by profile and may include automatic Start/Stop deactivation, speed-warning controls, drive modes or selected driver-assistance settings. Unsupported switches—and an empty section—are not shown.

The screenshots use the most feature-complete JAECOO profile. Your list may be shorter or contain different options. A visible switch does not guarantee support across every trim level or firmware version of the same model.

If a feature behaves unpredictably, return its switch to the previous state and verify that the correct profile is selected. Do not use another model's profile as a workaround.

8. Comfort automations

Comfort automations activate a feature when the vehicle starts and the configured conditions are met. Depending on the vehicle, you may be able to configure seat heating and ventilation, steering-wheel heating, and windscreen or rear-window heating.

Select a driver

The Driver 1, Driver 2 and Driver 3 tabs store separate automation settings. Select the driver before changing any cards. Use Driver 1 for all drivers applies a single shared set instead.

Configure an automation card

Each card has three main controls:

1. Feature icon and level. Tap the large seat, steering-wheel or window icon. Seat controls cycle through the available levels and then off; steering-wheel and window heating toggle between on and off.
2. Left slider: operating time. Set how long the feature should remain active. A value of 0 minutes means JCarTools will not switch it off by timer.
3. Right slider: temperature threshold. Heating starts when the outside temperature is below the selected value; ventilation starts when it is above that value.

Features that can use this type of automation

• driver and passenger seat heating;
• driver and passenger seat ventilation;
• steering-wheel heating;
• windscreen heating;
• rear-window and mirror heating.

Shared timing limits

The “Activation time limit” card applies to all temperature-based automations:

• Check outside temperature. When enabled, each automation uses its temperature threshold. If disabled, those thresholds are ignored.
• Minimum break between trips. This prevents automations from running again after a short stop. For example, a 10-minute value prevents a new activation if the vehicle was off for less than 10 minutes. A value of 0 disables this limit.
• Activation window after startup. This defines how long after the head unit starts an automation may still activate. A value of 0 leaves the window unrestricted.

Remote start and sunshade

“Run automations during remote vehicle start” allows the configured comfort scenarios to operate after a remote engine start, so supported cabin features can begin heating or ventilation in advance.

“Automatically open the sunshade” is a separate option. At vehicle startup, JCarTools sends the opening command if the shade is closed and the selected profile supports the function.

9. Floating button, multi-button, gestures and steering-wheel controls

Floating button

The standard floating button performs one selected action. Enable “Show floating button”, then choose its action. A frequently used app or screen is a good first test.

To reposition the button, enable its movement control and drag it to a clear area. Disable movement afterwards so it stays in place. Do not cover climate controls, camera views, system warnings or factory controls.

Multi-button

The multi-button provides access to several actions. Enable it and select “Configure” to choose the commands. Keep the list short enough that the main actions remain easy to reach.

Gestures and edge swipes

You can assign separate actions to upward, downward, left and right gestures. Depending on the profile, JCarTools may also provide grouped gestures and edge-swipe settings. Leave unused directions set to “Not assigned”.

1. Assign one safe action, such as opening navigation.
2. Test it several times while parked.
3. Make sure it does not interfere with factory swipes, notifications or the system Back gesture.
4. Configure the remaining directions only after the first one works correctly.

Steering-wheel buttons

Supported profiles can assign actions to compatible physical buttons. Test short and long presses with a simple command first, and confirm that the factory function still behaves as expected. Available buttons and actions depend on the vehicle.

10. JCarTools voice assistant

The voice assistant is configured separately from the floating button. Enable “Voice assistant” on the main screen and select “Configure”. The assistant window contains the recognition language, activation method, spoken phrases and their actions.

1. Select the recognition language

Open “Speech recognition language”, choose the required language model and select “Apply”. Another model may need to be installed before use. Only one recognition language is active at a time, so create every command in that language.

2. Choose how to activate the assistant

• Wake phrase. Leave widget activation disabled and enter a short word or phrase in the activation field.
• Widget press. Enable widget activation so no wake phrase is required.

3. Add a voice command

1. Select “Add command”.
2. Enter a short phrase that is easy to pronounce consistently.
3. Choose an action from the list.
4. Leave the command enabled and select “Save”.
5. Close the window and test the command while parked.

Write numbers as words in spoken phrases, and do not mix languages within one command set.

Example commands

• “Navigation on cluster” → display the selected app on the instrument cluster;
• “Open the sunshade” → open the supported sunshade;
• “Driver two” → select the corresponding driver profile;
• “Black screen” → start black-screen mode.

The available actions depend on the profile. If recognition is unreliable, shorten the phrase, remove similar commands and verify the selected language.

11. Final check

• The correct make-and-model profile is selected, and the available sections updated immediately.
• Navigation opens manually on the intended screen and closes correctly.
• Autostart has been tested with one app first.
• Widgets do not cover factory controls or warnings.
• Temperature-based automations do not conflict.
• Buttons, gestures and voice commands run only once per action.
• Settings remain saved after the vehicle is fully switched off and started again.
