System Nissan Connect 1 (also known as Nissan Connect Navigation) installed on the model Qashqai J11, X-Trail T32, Juke F15 and other cars of the concern from 2013 to 2018. Despite the release of newer versions (Nissan Connect 2 And Nissan Connect Services), the first generation remains in demand due to its ease of integration and upgradeability. However, when upgrading or repairing, owners are faced with a problem: official documentation for pinout of connectors either missing or scattered according to the service manuals.

In this article we have collected current data on the pinout of the main connectors Nissan Connect 1, including ISO connectors, CAN bus, USB/AUX And rear view camera. The information is based on analysis of circuits with ETM (Electrical Troubleshooting Manual) for Qashqai 2014-2017 And X-Trail 2014-2018, as well as data from enthusiasts who upgraded to Android Auto or Apple CarPlay. Particular attention is paid undocumented contacts, which are often ignored in standard instructions, but are critical for the correct operation of the system.

What connectors does Nissan Connect 1 use?

Head unit Nissan Connect 1 connects to the car through several key connectors, each of which is responsible for certain functions:

  • 🔌 Main ISO connector (A) — power supply (+12V, ACC, ignition) and speakers (4 channels).
  • 📡 CAN bus connector (B) — data exchange with the body control unit (BCM) to display information on the display (eg tire pressure, fuel consumption).
  • 🎵 Audio/video connector (C) — connection USB, AUX, rear view cameras and antennas.
  • 🔄 Control connector (D) — buttons on the steering wheel and touch screen (only for versions with navigation).

Important: depending on the vehicle configuration and delivery region (Europe, Japan, USA) pinout may vary slightly. For example, in Qashqai for the market JDM (Japan) no support Apple CarPlay, and in European versions a separate connector can be added for DAB radio.

Below is a table with connector designations for the most common configuration (European version Nissan Connect 1 with navigation):

Connector designation Case color Number of contacts Purpose
A Black 16 Power and Speakers (ISO 10487)
B Gray 8 CAN bus (High/Low), signals from BCM
C White 20 USB, AUX, rear view camera, antenna
D Brown 12 Controls (steering wheel buttons, sensor)
⚠️ Attention: In vehicles with the system Bose connector A may have additional contacts to control the amplifier. Connecting a standard head unit without an adapter will result in no sound!

Main ISO connector pinout (A)

Connector A (black, 16 pins) is responsible for power supply and connecting speakers. Its pinout is standardized and corresponds ISO 10487, but with some special features for Nissan:

  • 🔋 Contacts 1-8 — power and control:
    • 1 — +12V constant (yellow wire).
    • 2 — +12V ACC (red wire, turns on when you turn the key).
    • 3 — GND (black wire, ground).
    • 4 — Illumination (orange, button illumination).
    • 5 — ANT Control (blue, antenna control).
    • 6 — Mute (not used in the basic configuration).
    • 7 — CAN-H (green, only for versions with navigation).
    • 8 — CAN-L (green-black).
  • 🔊 Contacts 9-16 — audio outputs to speakers:
    • 9 — FL+ (front left, white).
    • 10 — FL- (front left, white and black).
    • 11 — FR+ (front right, gray).
    • 12 — FR- (front right, gray-black).
    • 13 — RL+ (rear left, green).
    • 14 — RL- (rear left, green-black).
    • 15 — RR+ (rear right, purple).
    • 16 — RR- (rear right, purple-black).

To connect an alternative head unit (for example, Pioneer or Sony) adapter required ISO → Nissan, since standard ISO connectors not compatible with original wiring. Please note: in versions with Bose signals to the speakers are supplied through an amplifier, so direct connection to the connector A not enough.

💡

If there is no sound after installing a new head unit, check for Bose amplifier in the trunk (usually next to the spare tire). In this case you will need a bypass adapter, e.g. Nissan Bose Emulator.

CAN bus: pinout and connection features

Connector B (gray, 8 contacts) is responsible for exchanging data via CAN bus between the head unit and the body control unit (BCM). This bus is used to display information from vehicle sensors on the screen:

  • 📉 Tire pressure (TPMS).
  • ⛽ Fuel consumption (instant and average).
  • 🚗 Power reserve.
  • ⚠️ Fault warnings (e.g. Check Engine).

Connector pinout B:

Contact Wire color Purpose
1 Green CAN-H (high level)
2 Green-black CAN-L (low level)
3 Red +12V (power supply for CAN module)
4 Black GND
5 Blue Speed Pulse (speed signal)
6 Yellow Reverse (reverse gear signal)
7 Orange Illumination (brightness adjustment)
8 Purple Steering Wheel Controls (steering wheel buttons)

An important nuance: if you install a third-party head unit (for example, on Android), for correct operation CAN buses will be required CAN adapter (For example, Nissan CAN Bus Interface from Dension or Connects2). Without it, the screen will not display data from the car, and the buttons on the steering wheel will stop working.

⚠️ Attention: Connecting an incompatible device directly to CAN bus may cause errors in BCM and lead to Check Engine. Always use certified adapters!
📊 What system do you use in your Nissan?
  • Nissan Connect 1 (original)
  • Android Auto (via adapter)
  • Apple CarPlay (via adapter)
  • Third party head unit
  • Other

USB/AUX connector and rear view camera (C)

White connector C (20 contacts) - one of the most complex in Nissan Connect 1, as it combines several functions: USB, AUX, rear view camera and antenna. Its pinout varies depending on the configuration, but the basic circuit is as follows:

  • 🔌 USB:
    • Contact 1 - USB+ (D+) (green).
    • Contact 2 - USB- (D-) (white).
    • Pin 3 - +5V (red).
    • Pin 4 - GND (black).
  • 🎧 AUX:
    • Pin 5 - AUX-L (left channel, white).
    • Pin 6 - AUX-R (right channel, red).
    • Contact 7 - AUX-GND (black).
  • 📹 Rear view camera:
    • Contact 10 - Video+ (yellow, composite signal).
    • Contact 11 - Video-GND (black).
    • Contact 12 - Reverse Trigger (blue, +12V when reverse gear is engaged).

Feature Nissan Connect 1 — the rear view camera is activated not only by a signal from Reverse, but also data on CAN bus. If you are connecting a third-party camera, you may need a signal emulator (for example, Nissan Camera Emulator).

To connect Android Auto or Apple CarPlay through USB adapters like this are often used NissanConnect Upgrade, which are connected to the connector C and emulate the original device. However, such solutions may conflict with standard navigation.

Connecting steering wheel buttons (connector D)

Brown connector D (12 contacts) is responsible for control from the buttons on the steering wheel. Its pinout is standardized for all models with Nissan Connect 1:

Contact Purpose Wire color
1 Mode (mode switching) Red
2 Volume+ Green
3 Volume- Blue
4 Next Track Yellow
5 Previous Track White
6 Answer Call (answer the call) Orange
7 Hang Up (end call) Black
8 Voice Control (voice control) Purple
9 GND Brown

To operate the buttons on the steering wheel when installing a third-party head unit, you need CAN adapter or resistor modulator (For example, Pac SWI-RC). Without it, the buttons will be inactive, since the signals from them are transmitted via CAN bus, and not via analog wires.

If after installing the adapter the buttons do not work correctly (for example, Volume+ works like Next Track), you need to reassign functions in the head unit menu or update the adapter firmware.

How to check the functionality of the steering wheel buttons without a head unit?

For diagnostics, connect a multimeter in resistance measurement mode to the connector contacts D. When you press the buttons, the resistance should change:

- Volume+: ~1 kOhm

- Volume-: ~2 kOhm

- Mode: ~3 kOhm

If the resistance does not change, the problem is in the wiring or the buttons themselves (a common problem is oxidation of the contacts under the steering wheel).

Compatible with Android Auto and Apple CarPlay

Original system Nissan Connect 1 does not support Android Auto or Apple CarPlay. However, there are several ways to add this functionality:

  1. Firmware upgrade (not officially supported, but enthusiasts have developed custom solutions for Qashqai J11 And X-Trail T32).
  2. Installing the adapter (For example, NissanConnect Upgrade or Dension Gateway 500), which is connected to the connector C and emulates the original device.
  3. Replacing the head unit to a third party (for example, Pioneer AVH-Z5200BT or Sony XAV-AX5000) with support Android Auto/CarPlay.

The most reliable option is to use an adapter Dension Gateway 500which:

  • 🔄Keeps the standard display and control buttons.
  • 📱 Supports wireless connection Android Auto And CarPlay.
  • 🎵 Remains original navigation and radio functional.

The disadvantage of this solution is the high cost (from 500 euros) and the need for professional installation. An alternative is Chinese adapters (for example, Carlinkit or OAA), but they often conflict with CAN bus and may cause errors in BCM.

⚠️ Attention: When using Chinese adapters for Android Auto There may be problems with displaying engine speed and rpm on the screen. This is due to the fact that cheap devices do not correctly process data from CAN buses.
💡

If you need a stable job Android Auto without losing the functionality of the standard system, the best option is an adapter Dension Gateway 500 or Connects2 CTNISS001.

Common problems and their solutions

When working with Nissan Connect 1 owners often encounter typical malfunctions. Let's look at the most common ones:

  • 🔇 No sound after replacing the head unit:
    • Reason: amplifier adapter missing Bose.
    • Solution: install Bose Emulator or connect the speakers directly, bypassing the amplifier.
  • 📵 The buttons on the steering wheel do not work:
    • Reason: missing CAN adapter or incorrect connector pinout D.
    • Solution: Check the adapter connection (for example, Pac SWI-RC) and reconfigure the buttons in the head unit menu.
  • 📺 The rear view camera does not turn on:
    • Reason: no signal Reverse on pin 12 of the connector C or the emulator is faulty.
    • Solution: check the voltage on pin 12 (should be +12V when reverse gear is engaged) and set Nissan Camera Emulator, if you are using a third-party camera.
  • 🔋 The head unit does not turn on:
    • Reason: missing +12V ACC 2 connectors on pin A or a fuse has blown (usually F37 10A in the fuse box).
    • Solution: Check the fuse and voltage on pin 2 (should be +12V when turning the key).

If an error appears on the screen after installing a new device No CAN Bus Connection, this means that the adapter is not connected to the connector correctly B. Check:

  1. Polarity CAN-H And CAN-L (green and green-black wires).
  2. Availability of +12V power supply on pin 3.
  3. Integrity of wires (often frayed near the connector).
