Nissan Murano Z50 head unit: characteristics and problems
Standard audio system Murano Z50 presented in two main options:
- 📻 Basic version — Bose 6CD with monochrome display (resolution
320×240), support for CD/MP3 and AUX input. No USB or Bluetooth. - 🎵 Premium version — Bose with navigation (models KLH1-0C000 or KLH1-0C010), color screen
800×480, DVD player and voice control. The firmware is often outdated (version2.0–2.5).
Main complaints from owners:
- 🔊 Poor sound quality at high frequencies (even with the system Bose).
- 🗺️ Outdated navigation maps (last update for Russia - 2012).
- 📱 No integration with smartphones (no CarPlay/Android Auto).
- 🔋 Frequent mistakes
ERR-03orERR-05when reading disks.
⚠️ Attention: If your radio gives an error ERR-03, this may indicate a faulty laser reader. Trying to clean the lens with alcohol often makes the problem worse - use only special lens cleaners (CD Lens Cleaner).
Some problems can be solved programmatically. For example, update the navigation firmware to version 3.1 (latest official for Murano Z50). However, this will not add support for modern multimedia protocols. An alternative is to install an aftermarket radio with adapters to retain control from the steering wheel.

Step-by-step instructions for installing the radio
Replacing the radio in Murano Z50 requires caution, especially when working with connectors CAN buses. You will need:
- 🔧 Set of screwdrivers (phillips and flat).
- 🔌 Adapter for connecting ISO connectors (for example, Nissan 16-pin to ISO).
- 🎛️ Multimeter for checking voltage.
- 📄 Connection diagram (see below).
Step 1. Dismantling the old radio
- Disconnect the negative terminal of the battery.
- Remove the decorative panel around the radio (carefully pry up the clips with a flat-head screwdriver).
- Unscrew the 4 bolts securing the radio (at the corners).
- Disconnect the power and antenna connectors. Don't pull the wires!
Step 2. Connecting a new radio
Please use adapter for compatibility with CAN bus Nissan. Connect the connectors in the following order:
- Yellow wire (
Battery +12V) → constant plus. - Red wire (
Ignition +12V) → plus from ignition. - Black wire (
Ground) → mass. - Blue/White (
Power Antenna) → antenna control.
☑️ Check before first use
⚠️ Attention: If the radio does not turn on after installation, check the fuse F37 (10A) in the block under the hood. It is responsible for the audio system circuit and often burns out if there is a short circuit.
Sound settings and integration with the Bose system
Standard acoustics Bose in Murano Z50 has a unique configuration: 11 speakers (including a subwoofer) with individual amplifiers. When installing a non-standard radio, it is important:
- 🔊 Use outputs
RCAfor connection to the standard amplifier (located under the front passenger seat). - 🎛️ Disable the built-in equalizer of the radio and use the settings Bose.
- 📶 Check the phasing of the speakers (if connected incorrectly, the bass will be “blurry”).
For fine tuning:
- Enter the sound menu of the radio (for example, in Pioneer this is
Settings → Audio → Equalizer). - Select a preset
Flat(neutral). - Activate mode
Time Alignmentand set delays:- Front speakers:
0.0 ms. - Rear speakers:
2.5–3.0 ms. - Subwoofer:
5.0 ms.
- Front speakers:
How to check the phasing of speakers?
To check the phasing, use a test signal (100 Hz sine wave). If, when switching the polarity of one of the speakers, the bass becomes muffled, the polarity is incorrect. B Murano Z50 standard wiring: plus on the speakers is marked with a red marker.
If after adjustment the sound remains unsatisfactory, check the power supply circuit of the amplifier Bose. Connector contacts often oxidize C101 (located behind the glove compartment).
Updating the firmware of the head unit
Official updates for radios Murano Z50 were produced until 2014, but enthusiasts created unofficial firmware with support for modern formats. For example, firmware KLH1-Mod v2.1 adds:
- 🎵 Support
MP4,FLAC,AAC. - 🗺️ Updated maps Navteq 2022 (unofficial port).
- 📱 Emulation Bluetooth for streaming music.
Update instructions:
- Download the firmware from the forum NissanClub.ru (section
Murano Z50). - Format the flash drive to
FAT32(size no more than 32 GB). - Copy the firmware files to the root of the flash drive (the files should be called
UPDATE.BINAndMAPS.DAT). - Insert the flash drive into the USB port of the radio (located in the glove compartment).
- Press and hold the button
EJECTfor 5 seconds - the update process will begin (about 20 minutes).
⚠️ Attention: If during the update the radio gives an error UPDATE FAIL, do not remove the flash drive! Repeat the process, first checking the integrity of the files (MD5-hash must match the one specified on the forum).
After the update, reset the radio settings to factory settings (Settings → Reset → Full Reset). This will eliminate possible interface glitches.
Common problems and their solutions
Even after proper installation, problems may occur. Let's consider typical cases:
| Problem | Possible reason | Solution |
|---|---|---|
| The radio does not turn on | Incorrect connection CAN buses or fuse F37 |
Check the voltage on the yellow wire (should be 12V), replace the fuse |
