Standard multimedia system Nissan Murano Z51 (2015–2021 release) often requires firmware updates to fix bugs and add support Apple CarPlay/Android Auto or performance improvements. However, the firmware process has a number of nuances: from selecting the correct software version to the risk of the head unit being “bricked” in case of errors. In this article we will analyze official and unofficial update methods, as well as typical problems that owners face.

It is important to understand that updating the radio firmware is not the same as updating navigation maps. We're talking about reflashing here. system software, which controls the operation of the screen, audio system and smartphone connection interfaces. Incorrect actions may result in loss of functionality or even damage to the device. Therefore, before starting the procedure, check current firmware version (more on this below) and prepare a backup copy of your settings.

How to find out the current firmware version of the radio

Before downloading new files, you need to determine the current software version of your head unit. To do this:

  1. Start the radio by pressing the button POWER.
  2. Go to the settings menu: Settings → System → System information.
  3. Find the lines Version SW or Software Version - this is the firmware version.

B Murano Z51 the most common versions are 58.00.XXX (for systems with NissanConnect) and 2.00.XXX (for basic radios without navigation). If your version is older 58.00.500, the update may not be required - check the list of changes on the official website Nissan.

⚠️ Attention: If the system information indicates HW: 1.0, and you are trying to install firmware for HW: 2.0, the radio will stop turning on. Hardware versions incompatible!
📊 What is your radio firmware version?
  • 58.00.XXX (with NissanConnect)
  • 2.00.XXX (basic)
  • I don't know, haven't checked

Official sources of firmware for Murano Z51

The safest way is to download the firmware from Nissan official website or through the service NissanConnect Services. However, there are limitations:

  • 🔹 Official updates are only available for radios with NissanConnect (8-inch screen, CarPlay/Android Auto support).
  • 🔹 For basic versions (5-inch screen without navigation), there are no official firmwares - only unofficial modifications.
  • 🔹 Updates are linked to VIN code car - you won’t be able to download files without it.

To get the firmware through the official channel:

  1. Go to the site Nissan Owners Portal (for USA) or Nissan Russia.
  2. Enter VIN your Murano Z51 (located on the driver's side windshield or in the registration certificate).
  3. In the section Software updates find the files for the multimedia system.

If there is no official update for your version, you can contact your dealer - sometimes they have access to proprietary firmware. However, this is a paid service (from 3,000 to 8,000 rubles depending on the region).

What should I do if there is no firmware for my radio on the website?

If there is no official update, check alternative sources (see next section). You can also try contacting the service center with a request to check the availability of firmware through Nissan’s internal channels. Sometimes dealers receive updates later than they appear on public resources.

Alternative firmware: risks and opportunities

When there are no official updates or they do not solve your problems (for example, there is no Android Auto), owners Murano Z51 resort to unofficial firmware. They can be found on forums like Drive2, XDA Developers or specialized resources like NaviPlus.

Advantages of alternative firmware:

  • 🔧 Adding support Android Auto And Apple CarPlay for basic radios.
  • 🎵 Improved audio processing (e.g. equalizer with more bands).
  • 🗺️ Updated maps for navigation (if the firmware includes them).

However, there is also serious risks:

  • ⚠️ Loss of warranty (if the car is under warranty).
  • ⚠️ Possibility of “scrapping” the radio if there is an installation error.
  • ⚠️ Unstable operation of the system (freezes, reboots).

Before installing unofficial firmware, be sure to:

Download the firmware from a trusted source (check reviews)

Create a backup of your current firmware (if possible)

Prepare a FAT32 format USB drive (maximum 32 GB)

Charge your car battery or connect a charger

-->

Critical information: Some alternative firmware for the Murano Z51 require flashing the radio control unit (MCU). This is a complex procedure that can result in loss of communication with the steering wheel buttons or climate control. Without experience, it is better to turn to specialists.

Step-by-step instructions for flashing radio firmware

The process for updating firmware via USB drive is the same for most versions of radios Murano Z51. You will need:

  • 📁 Firmware file in the format .up or .zip (do not unpack!).
  • 💾 USB flash drive up to 32 GB, formatted in FAT32.
  • 🔋 Car battery charge is at least 70% (or connected charger).

Step 1: Preparing the USB Drive

  1. Format the flash drive to FAT32 (use the official utility SD Formatter for reliability).
  2. Copy the firmware file to root directory Flash drives (not in folders!).
  3. Rename the file according to the instructions (for example, NSMU_Z51_58.00.500.up).

Step 2. Firmware update

  1. Insert the USB into the radio port (usually located on the right or bottom of the screen).
  2. Start the radio and go to Settings → Software Update → USB Update.
  3. Confirm the start of the process. The radio will reboot and begin installation (this will take 10–20 minutes).

Step 3. Completion

After the update, the radio will automatically reboot. Do not remove the USB or turn off the ignition until the process is complete! If the screen is stuck on the logo Nissan longer than 10 minutes, it means an error has occurred - see the "Troubleshooting" section.

1) Flash drive format (must be FAT32, not exFAT or NTFS).

2) File name (must match the requirements of the instructions).

3) File integrity (download it and check the MD5 checksum).-->

Compatibility table for firmware and hardware versions

Not all firmware is suitable for all versions of radios Murano Z51. Below is a compatibility table based on data from forums and service manuals:

Hardware version (HW) Radio model Supported firmware versions Notes
1.0 Basic (5" screen, no navigation) 2.00.100–2.00.400 There are no official updates. Only unofficial modifications with a risk of unstable operation.
2.0 NissanConnect (8" screen, with navigation) 58.00.100–58.00.700 Official firmware is available on the Nissan website. Versions above 58.00.500 support CarPlay/Android Auto.
2.1 NissanConnect (updated version, 2019–2021) 59.00.100–59.00.300 Requires mandatory updating through the dealer when replacing the radio.
⚠️ Attention: If your radio has a hardware version 2.1, but the firmware is lower 59.00.100, USB update may lock up the system. In this case, special equipment is required for unlocking (the cost of the service is from 5,000 rubles).

Solving common problems after flashing

Even if the update is successful, problems may occur. Let's look at the most common of them and how to eliminate them:

  • 🔄 Radio stuck on Nissan logo

    Reason: Incompatible firmware or interrupted update process.

    Solution: try it forced reset (press and hold the button POWER for 10 seconds). If it doesn’t help, you need to reflash it through the service mode.

  • 🔊 No sound after update

    Reason: resetting the equalizer settings or a conflict with external devices (for example, an amplifier).

    Solution: Check your audio settings in the menu Settings → Sound → Equalizer and reset them to factory settings.

  • 📱 Apple CarPlay/Android Auto not working

    Reason: inactivated function or outdated smartphone firmware.

    Solution: Update your smartphone to the latest version of iOS/Android and check the cable (must support data transfer).

If the radio does not turn on at all after unsuccessful firmware, try the following:

  1. Disconnect the car battery for 10 minutes (this will reset temporary errors).
  2. Repeat the firmware procedure with another flash drive (sometimes the problem is in the drive).
  3. If all else fails, contact service and ask to flash the radio via Diagnostic Mode (special software and adapter required).
💡

If after flashing the firmware the radio gives an error ERROR 03, this means the firmware file is damaged. Download the file from the official source and repeat the procedure.

Firmware rollback to previous version

Sometimes after an update critical bugs occur (for example, constant reboots or lack of communication with the car’s CAN bus). In such cases it is required rollback to previous firmware version.

The rollback process is similar to the update, but has its own characteristics:

  • 🔙 To roll back you need exact version of previous software (You cannot install arbitrary old firmware).
  • 🔧 Some radios block downgrade - in this case you will need service mode.
  • ⚠️ Rollback can reset all settings (keep your favorite radio stations and equalizer).

To find the previous firmware version:

  1. Check the archives on the forums (eg. Drive2 or XDA).
  2. Contact the service center - they may have backup copies of the firmware.
  3. Use utilities like Nissan Consult (diagnostic cable required).

If rolling back doesn't help, the problem may be hardware incompatibility - for example, the new firmware has changed the structure of the memory section. In this case, only a complete flashing via J2534 programmer (the service costs from 7,000 rubles).

FAQ: Frequently asked questions about firmware for Nissan Murano Z51 radio

Is it possible to flash a radio without USB, via Wi-Fi or Bluetooth?

No, official firmware for Murano Z51 can only be installed via a USB drive. Some alternative firmwares support software updates OTA (by air), but this is risky - if the connection is lost, the radio may fail.

Why doesn't the radio see the firmware file on the flash drive?

There are several reasons:

  • The flash drive is formatted in NTFS or exFAT (need FAT32).
  • The file name does not meet the requirements (for example, it contains Cyrillic or spaces).
  • The file is damaged (check the checksum MD5).
  • The USB port of the radio is faulty (try another drive).
Is it possible to flash a radio from a Murano Z51 to another Nissan model?

Technically possible, but highly not recommended. Even if the hardware versions are the same (HW: 2.0), the firmware may not work correctly with the CAN bus of another vehicle. This will lead to errors in the operation of the climate control, steering column switches or security system.
