Multimedia system Nissan Connect 1 has become a standard solution for many models Nissan, including Qashqai J11, X-Trail T32 And Juke F15. Despite the convenient interface and wide functionality, owners are often faced with the need to connect additional equipment - be it a rear view camera, an external amplifier or a diagnostic scanner. This requires knowledge connector pinout, which is rarely documented in official manuals.

In this article you will find detailed pinout diagram of all Nissan Connect 1 contacts indicating voltages, purpose and possible connection options. We will analyze the standard and hidden functions of the connector, and also provide practical advice on modifying the system without the risk of damaging the electronics. Particular attention is paid security — you will learn which contacts should not be closed and how to avoid common mistakes when working with wiring.

What is Nissan Connect 1 and where is the connector located?

Nissan Connect 1 - this is the first version of a multimedia system with a touch screen that was installed on cars Nissan from 2013 to 2017. Unlike later versions (Nissan Connect 2 And Nissan Connect EV), it does not support Apple CarPlay And Android Auto, but has a connector for connecting external devices.

The main pinout connector is located on the rear panel of the head unit. To access it, you must:

  • 🔧 Remove the decorative panel around the radio (usually secured with latches).
  • 🔌 Disconnect the power connector and antennas (carefully so as not to damage the cables!).
  • 🔍 Find a 26-pin connector (most often white or gray) with markings CN-105 or MULTIMEDIA.

On some models (for example, Nissan Qashqai 2015+) the connector can be hidden under metal protection. In this case, you will need a screwdriver T20 for dismantling fasteners. Do not confuse the main connector with the power connector - the latter has 12 contacts and is marked as POWER.

Full pinout diagram for Nissan Connect 1 connector

Below is a table with the pinout of a standard 26-pin connector. Please note that some models may have slightly different pin assignments (e.g. Nissan X-Trail T32 pin 13 is sometimes used for CAN-H instead of VIDEO IN).

Contact number Purpose Voltage (V) Wire color Notes
1 GND (Common minus) 0 Black Main mass of the system
2 +12V (ACC) 12 (with ignition on) Red Power when turning the key
10 CAN-L 2.5 (standby) Green/white Low speed CAN bus
15 VIDEO IN (RCA) 1.0 (signal) Yellow To connect a rear view camera
26 USB D+ 5 (with active connection) Purple Data+ for USB devices

The complete diagram of all 26 contacts can be downloaded here (PDF, 1.2 MB). Please note that contacts 17 And 18 (AUX L/R) on some versions Nissan Connect 1 inactive - their activation requires firmware.

💡

Before working with the connector, disconnect the battery for 10 minutes - this will release residual charges in the capacitors and protect the system from short circuits.

Assignment of key contacts: what can be connected?

Not all connector pins are equally useful for modifications. Let's look at the most popular ones:

  • 📹 Pins 15 and 16 (VIDEO IN And VIDEO GND): Designed to connect an analogue rear view camera. The signal is sent via RCA, but requires activation in the service settings menu (access code: 1234 or 3456).
  • 🔊 Pins 5 and 6 (AUX IN L/R): Audio input for external devices. Disabled on some firmware - to activate it you need Nissan Consult III or special software.
  • 📡 Pins 10 and 11 (CAN-L And CAN-H): Connection to the vehicle's CAN bus. Allows data to be read from the ECU (for example, for Torque Pro), but requires an adapter ELM327 with support CAN 500 Kbps.
  • 🔌 Pins 25 and 26 (USB D- And USB D+): standard USB 2.0 for flash drives and smartphones. Maximum current - 500 mA, so powerful devices may not be detected.

Contact deserves special attention 20 (MUTE). When applying for it +12V the system automatically mutes the sound - this is convenient for integration with a radar detector or Hands-Free system. However do not supply voltage higher than 14V - this can burn the input transistor.

How to activate hidden functions via CAN bus?

Additional options can be unlocked via the CAN bus, such as displaying tire pressure or transmission temperature. To do this you need a diagnostic scanner (for example, Launch X431) and block access BCM. On the menu Configuration select Multimedia and activate the desired options. Caution: incorrect settings may result in an error U1000 (loss of communication with CAN).

Typical mistakes when working with pinouts

Even experienced auto electricians make mistakes when connecting to Nissan Connect 1. Here are the most common:

⚠️ Attention: Never connect +12V to contacts CAN-H or CAN-L! This will instantly disable the unit BCM and will require its reflashing (cost from 15,000 ₽).
  • ⚡ Short circuit of contacts 2 and 3 (+12V ACC And +12V BAT): causes the fuse to trip F37 (10A) in the block under the hood. After replacing the fuse, the system may not turn on and will require a reset via Nissan Consult.
  • 🔄 Confused VIDEO IN And AUX IN: The rear view camera will output audio instead of video. Check the wire markings!
  • 📱 Connecting a smartphone to USB without a resistor: on some firmware this causes an error U0100 (loss of connection with TCM). Use a power isolated USB hub.

Another common problem is no camera image after connection. Reasons:

  1. The entry to the service menu is not activated (you need to go to Engineering Mode and turn on Camera Input).
  2. Wrong polarity VIDEO IN (check with an oscilloscope - the signal should be 1V pp).
  3. Conflict with another device on the CAN bus (disable all additional modules and check again).

☑️ Check before connecting the rear view camera

How to modify Nissan Connect 1: practical tips

If you need to expand the functionality of the system, here are some proven solutions:

  1. Connection Apple CarPlay/Android Auto:

    Not officially supported, but you can install an adapter CarPlay2Air or AAWireless via USB connector. For correct operation you need:

    • 📱 Radio firmware no lower 5.0.2.18 (checked in Settings → About the system).
    • 🔌 Adapter supported USB OTG.
    • 🔄 Disable Energy Saving Mode in Bluetooth settings.
  • Installing an external amplifier:

    Use contacts 21-24 (FRONT/Rear SPEAKER OUT) to output the signal to an amplifier. Please note that the signal level is low (2V), so it may be necessary line-out converter.

  • Integration with climate control:

    Via the CAN bus, you can display data on the interior temperature on the screen. For this you need a module Nissan CAN Gateway (about 8,000 ₽) and firmware with support Climate Data.

    • To diagnose errors after modifications, use the command in Nissan Consult:

    SCAN ALL → MULTIMEDIA → READ DTC

    If an error appears B15A0 (USB fault), check the circuit +5V on contact 26 multimeter.

    💡

    Any modifications to the CAN bus require testing to ensure there are no conflicts with other units (ABS, ESP, SRS). Use CAN analyzer for traffic monitoring.

    Diagnosis of faults by pinout

    If Nissan Connect 1 stopped working after connecting the devices, use these instructions:

    Symptom Possible reason Solution
    The screen does not turn on, but the backlight is on Short circuit in the circuit +12V BAT (pin 3) Check the fuse F10 (15A) in the salon block
    There is sound, but no picture The cable between the screen and the main unit is damaged Disassemble the panel and check the connectors LCD1 And LCD2
    Error NO USB DEVICE when connecting a flash drive Resistor faulty R120 on board (100 Ohm) Replace the resistor or connect USB via a hub

    For in-depth diagnostics, use Nissan Consult III/IV or Launch X431. If the system gives an error U1000, this indicates problems with the CAN bus. Check:

    • 🔌 Integrity of wires CAN-H And CAN-L (the resistance between them should be 60 ohm).
    • 🔋 Contact voltage: CAN-H — 2.5V, CAN-L — 2.5V (deviation more 0.5V speaks of a break).
    • 🚗 Block state BCM (often fails during power surges).
    ⚠️ Attention: If after diagnostics there is an error U1000 remains, do not try to reset it manually through Clear DTC! This may result in loss of connection with ABS And ESP. Contact the service to check CAN terminators.
