Crossover owners Nissan Murano second generation (Z51 body) are often faced with the need to upgrade the standard multimedia system. The original interface, despite its reliability, quickly becomes outdated, not supporting modern formats for navigation, streaming and multimedia content.
The market offers a wide range of solutions: from simple adapters for Apple CarPlay to powerful Android tablets that completely replace the standard head unit. Choosing the right device is critical, as incorrect integration can disrupt the operation of the climate control or parking sensors.
In this article we will look at the key aspects of choosing, installing and configuring a radio for Nissan Murano Z51. You will learn how to preserve the functionality of the standard buttons on the steering wheel, configure a rear view camera with dynamic markings, and ensure stable navigation without loss of sound quality.
Features of the standard system and reasons for replacement
Standard multimedia installed at the factory in Nissan Murano Z51, is based on proprietary software. Although it provides basic functionality, users often complain about slow touchscreen response and lack of support for modern video codecs. Software updates from the manufacturer occur extremely rarely and often do not bring the desired changes to the interface.
The main problem of standard systems is the closed architecture. You can't install third-party apps like Yandex.Maps, Waze, or YouTube, which makes long trips less comfortable. Additionally, the screen is often low-resolution, causing navigation text to appear washed out in bright sunlight.
Changing the head unit allows you to integrate Android Auto and Apple CarPlay, turning the car interior into a modern entertainment center. It is important to understand that the replacement should not affect the operation of the on-board computer and security system. A high-quality CAN bus adapter solves this problem while maintaining all vehicle functions.
If you are looking for a solution for Murano Z51, pay attention to models with support OBD2 diagnostics and 3G/4G modems. This will allow you to access the Internet directly from the cabin, without depending on a smartphone connection via Bluetooth.
Criteria for choosing a new multimedia system
When selecting a head unit for a crossover Nissan Murano Z51 Several technical parameters need to be taken into account. The first and most important thing is the size and shape of the screen frame. Depending on the year of manufacture and configuration, the shape of the opening may differ slightly, so universal frames may not fit perfectly.
The processor platform plays a key role in system performance. For comfortable work with cards and video players in multitasking mode, it is recommended to choose models with at least 4 GB of RAM and 64 GB of built-in flash memory. Weak processors will cause freezes when switching between applications.

- 📱 Availability of Wi-Fi and Bluetooth 5.0 modules for stable connection of smartphones
- 📡 Built-in 4G modem or SIM card slot for accessing the Internet without a phone
It is also important to pay attention to the type of screen. IPS matrices provide wider viewing angles and better color reproduction, which is critical for watching videos by passengers from the rear seats. Also check for an amplifier output if your car has a premium Bose audio system.
⚠️ Attention: Do not buy radios with screens that are not adapted for car lighting. When the headlights are turned on, the screen brightness should automatically decrease to avoid blinding the driver at night.
Installation and wiring process
Installing the head unit in Nissan Murano Z51 requires accuracy and understanding of the connection diagram. The first step is to dismantle the standard panel and remove the original unit. In most cases, this does not require removing the entire torpedo; just carefully snap off the plastic fasteners around the perimeter.
After removing the standard radio, you need to connect the adapter block. It is through this adapter that signals are transmitted from the vehicle’s CAN bus to the new system. Errors in connecting the power cords may result in a short circuit or inability to turn on the device.
☑️ Preparation for installation
The connection between the power connector (ISO) and the adapter must be tight. If the contacts are loose, the system will periodically reboot or lose the signal from the rear view camera. It is recommended to use electrical tape or heat shrink tubing to secure connections and protect against vibration.
If you are not confident in your abilities, it is better to entrust the installation to specialists, since incorrect installation can damage the wiring of the door cards or instrument panel. However, if you have a tool and a diagram, the procedure takes no more than 40 minutes.

Setting up the CAN bus and maintaining functionality
The most difficult part of the setup is the correct configuration CAN buses. This system is responsible for the exchange of data between the on-board computer and multimedia. Without the correct settings, you may lose information about engine temperature, fuel level or door status on the screen of your new radio.
In the device settings menu you need to select the car model Nissan, Z51 generation and year of manufacture. Then comes the calibration of the buttons on the steering wheel. It is often necessary to manually assign functions (volume, track switching, voice assistant) to physical buttons, since automatic detection does not always work correctly.
- 🛠️ Checking the display of data on the dashboard after switching on
- 🎛️Adjust microphone sensitivity for voice commands
- 🔊 Testing the operation of the amplifier when switching to reverse gear
Pay special attention to setting up the parking sensors. In some firmware, you must manually specify the type of sensors so that they are displayed correctly when reversing. Ignoring this item may result in the system issuing false warnings or not responding to obstacles.
What to do if the buttons on the steering wheel do not work?
Check if the correct CAN bus protocol is selected in the settings. Try rebooting the radio. If the problem is not resolved, you may need to update the CAN bus adapter firmware via USB port.
⚠️ Attention: When changing the CAN bus protocol, the system may reset all settings to factory settings. Before changing settings, make a note of the current configuration.
Integration of cameras and driver assistance systems
Connecting a rear view camera to a new radio requires setting up dynamic markings. Static lines do not take into account the steering angle, which reduces the safety of maneuvering in narrow spaces. For Nissan Murano Z51 Cameras with CAN bus support that automatically change the trajectory of lines are ideal.
Many modern radios support connecting multiple cameras (front, rear, side). This creates a 360-degree effect if the cameras are installed correctly. However, this function requires a specific software module, which is often included with expensive models.
To adjust the image you need to go to Settings → Camera → Camera Type. Select the mode that matches your camera (for example, "Nissan" or "Universal"). Adjust brightness, contrast and saturation so that the picture is clear even in the twilight.
If you're setting up a wide-angle camera, keep in mind that objects will appear further away than they actually are. It is recommended to practice in a parking lot before starting active use in order to get used to perspective distortions.
Audio system and sound quality improvement
Many owners Murano Z51 choose radios with support DSP (digital signal processing). This allows you to customize channel time delays and equalizer for a specific car interior. Stock systems often have flat sound that doesn't bring out the full potential of Bose speakers.
Connecting an external amplifier via RCA cables requires care. Wires must be shielded to avoid interference and background noise. Make sure the cables are long enough to run from the front speakers to where the amplifier is installed, usually behind the rear panel.
