Intro – The Hidden Complexity of Murano Z51 Upgrades
The Nissan Murano Z51 (2009–2014) is one of the most complex models to upgrade with an Android head unit. Many owners—and even professional installers—expect a simple plug-and-play job. In reality, the factory BOSE system, multiple OEM head unit variations, and unique wiring requirements mean that without the right preparation, you can end up with no sound, missing functions, or a costly reinstallation.
Before you buy or install, here are the key things you need to know to ensure your upgrade is smooth and successful.
1. Identify Your Trim Level: Low Spec vs. High Spec
Low Spec (Non-BOSE)
-
The factory head unit is retained.
-
Audio is output through the AUX port into the factory speakers.
-
Only one type of OEM head unit exists for low-spec Murano models, so the wiring harness is relatively easy to match.
High Spec (BOSE)
-
The factory head unit is removed and replaced with the Android unit.
-
The Android unit must have a built-in amplifier to drive the BOSE system.
-
There are multiple OEM head unit versions, meaning different wiring harness and CANBUS requirements.

2. Multiple OEM Head Unit Variations
This is where most mistakes happen.
-
Low-spec Murano: 1 OEM head unit → 1 harness type
-
High-spec Murano: 4–5 OEM head unit variations → 3 different harness sets
-
Each OEM head unit type requires a matching harness and CANBUS decoder for full functionality.
If you choose the wrong harness, you risk losing sound, steering wheel controls, or climate control functions.
3. CANBUS Decoder Matching
The CANBUS decoder is the bridge between your Android head unit and the vehicle’s electronic systems. Without the right one:
-
Climate control display and adjustment may disappear
-
Steering wheel buttons will stop responding
-
Some BOSE audio functions will be disabled
Matching the CANBUS decoder to your OEM head unit type and model year is crucial.
4. Common Pitfalls to Avoid
-
Wrong harness purchase – leads to non-functional audio or missing features
-
No CANBUS decoder or wrong model – steering wheel buttons and AC controls stop working
-
Mixing trim level solutions – installing a low-spec harness in a high-spec BOSE model results in no sound
-
Not verifying OEM head unit type – guessing instead of confirming
