Before Installation
2.1 Precautious
·Do not install this unit in vehicles without an ACC (accessory) position:
Without an ACC circuit, the display may remain powered even after the ignition is turned off, which can drain the vehicle battery.
·Ensure all ground wires are connected to a common grounding point:
Proper grounding is essential for system stability and safety.
·Avoid trapping wires under screws or moving parts:
Secure all cables carefully to prevent pinching or damage—especially near seat rails or adjustable components.
·Always switch off the ignition before making any wiring connections:
This prevents potential short circuits or damage to the electrical system.
·Connect the yellow (constant power) and red (ACC power) wires only after all other connections are completed:
This reduces the risk of accidental power surge or misconnection.
·Insulate all unused or exposed wire ends with electrical tape:
Leaving wires uninsulated may cause short circuits or safety hazards.
·Power lead (yellow wire) warning:
If connecting this unit alongside other stereo components, ensure the car’s circuit amperage rating exceeds the total amperage required by all connected devices. Failure to do so may overload the circuit.
2.2 Extra Accessories for Installing a Universal Fit Headunit

Module 3: Steering Wheel Control Wiring
Upgrading from a factory head unit to an ATOTO car stereo does not mean sacrificing the functionality of your factory steering wheel controls. With the help of aftermarket solutions from companies like Metra, PAC, and Crutchfield, you can retain control over essential functions such as volume, mode, and track selection by installing an interface module to integrate your original steering wheel controls with your new ATOTO headunit.
1. Types of Steering Wheel Control Signals
There are two main types of steering wheel control signals:
·Resistor-Based Analog Signals
·CANBUS-Based Data Signals
For CANBUS-Based Signals:
If your vehicle uses CANBUS-based steering wheel control signals, you will need to purchase a compatible CANBUS data interface. Without this interface, the factory steering wheel controls cannot be retained after replacing your car stereo with an aftermarket unit.
For Resistor-Based Analog Signals:
If your vehicle uses resistor-based analog signals, you can either:
·Purchase a steering wheel control interface module.
·Locate the steering wheel control wires in your car’s harness (or wiring harness) and connect them directly to the corresponding steering wheel control wires on the ATOTO power harness.
2. Recommended Resources for Wiring Harnesses or CANBUS Interfaces
Here are some recommended resources to find compatible wiring harnesses or CANBUS interfaces:
·United States/Canada:
Metra Online, Crutchfield, https://pac-audio.com, Amazon, ebay and etc.
·Europe/Australia:
Connects2, Amazon, or eBay
·Japan:
Kanatechs, Rakuten, Amazon and etc.
3. ATOTO Power Harness Steering Wheel Control Wires
The latest ATOTO power harness includes two types of steering wheel control wiring options:
1.3.5mm Female Jack for SWC
2. Separate Steering Wheel Key Wires
Important: Use only one of these options—either the 3.5mm jack or the steering wheel key wires, not both.
4. Setting Up Steering Wheel Control
4.1 Wiring Methods:
【AI图解: The associated image illustrates an overview of the Wiring Methods.】
Note：The wiring diagram and interface layout are based on the X10G209E model as a reference. Please locate the corresponding interface positions according to your specific model.
There are two wiring methods depending on your setup:
Method 1:
If your purchased wiring harness includes a 3.5mm male jack for SWC, simply connect it to the 3.5mm female jack on the ATOTO power harness.
Method 2:
Step 1：If your wiring harness or car harness does not include a 3.5mm male jack but has steering wheel control wires:Connect the positive steering wheel control wires to either the “Steering Wheel Key(+)” or the “Steering Wheel Key #(+)” wire on the ATOTO power harness (sequence does not matter).
Step 2: Connect the steering wheel control ground wire to the black ground wire on the ATOTO power harness.
NOTICE:
·If the interface module requires selecting a head unit type, choose Pioneer.
·The “Steering Wheel Key(+)” and “Steering Wheel Key #(+)” wires serve the same function and are interchangeable.
4.2 Programming the Steering Wheel Control Buttons
Once the wiring is complete (via either the 3.5mm jack or the steering wheel control wires), program the steering wheel control buttons through the head unit's settings. Follow the step-by-step instructions provided in the ATOTO user manual to assign functions to each button(For detailed instructions on steering wheel control learning, navigate to Features > Steering Wheel Control (SWC) Learning Configuration.)
5. Troubleshooting Unrecognized Buttons
If some buttons cannot be programmed or recognized:
1.Verify that the steering wheel interface adapter/module is functioning properly and not defective.
2.If the resistance difference between certain buttons is too small for the head unit to recognize, try adding a resistor in series with one of the two steering wheel key wires. This may resolve the issue.
Safety Reminder
We strongly recommend completing SWC wiring under the guidance of a professional installer, especially when dealing with unfamiliar vehicle wiring systems.
Important Note:
For users in the United States, the X10 is compatible with the iDataLink Maestro module, which allows you to display engine performance metrics and other vehicle data directly on the touchscreen while retaining factory features for a wide range of vehicles.

This is where you’ll plug the FAKRA connector. Gently insert the FAKRA plug until it clicks into place securely.
2) Positioning the antenna module:
①Choose a flat and unobstructed surface inside the vehicle, such as the top dashboard near the windshield.
②Clean the surface and peel off the adhesive on the back of the red antenna base.
③Firmly press and mount the antenna in place. Avoid metal obstructions above the antenna to ensure signal strength.
6.MIC Input: External Microphone Input
Function: It is specifically designed to connect to our AC-MIC20 external microphone.
Items to look for before placement:
①Before using the AC-MIC20 external microphone, please ensure that the protective dustproof adhesive film covering the microphone mesh has been removed. Failure to remove this film may result in reduced audio quality during use.
②Do not place the microphone in front of air vents.
③If the vehicle has tweeters placed on sail panel, do NOT locate the microphone on
steering column area.
④The front of the microphone must not be blocked.
⑤Microphone should be firmly attached to mounting location.
⑥Do not cover the grille openings surrounding the microphone.
⑦To avoid excessive wind noise, do not place near the sunroof opening.
The location of the microphone can vary from different vehicles due to layout, interior materials, etc.

Module 8: Power & Ignition Wiring
Purpose: Supplies power to the head unit and ensures it turns on/off properly with vehicle ignition.
【AI图解: The associated image illustrates an overview of the Advanced Power & Ignition Wiring Connection.】
Note：The wiring diagram and interface layout are based on the X10G209E model as a reference. Please locate the corresponding interface positions according to your specific model.
How to Connect:
1.Connect the Chassis Ground (-) wire to the main ground wire on the original vehicle power supply. If the original vehicle connector does not have a main ground wire, connect to a clean, bare metal point on the vehicle chassis. Poor grounding may lead to noise or instability.
2.Connect the Constant / Battery Power (+) wire to a constant 12V battery source in the vehicle. This ensures system settings and memory are retained when ignition is off.
3.Connect the Accessory / Ignition (+) wire to the vehicle's ACC (Ignition) power source, which supplies power when the key is turned to ACC or ON position.
Note: It is recommended to follow the sequence of connecting the ground wire first, followed by the constant power wire, and finally the ignition wire. This minimizes the risk of short circuits or accidental power-related issues during the installation process.
Module 9: Supplying Power to the Head Unit
Power 15A Port: For supplying power to the head unit
Connection Instruction: Use the X10 Android head unit’s included 20-pin power cable to connect the Android head unit via the "POWER 15A port" to the corresponding original vehicle’s B+ battery positive wire. (Generally, a dedicated adapter is used for installation without the need to cut original wires.)
Important Reminder:
1.Complete all wiring connections (speakers, antennas, cameras, USB, etc.) before plugging in the POWER 15A connector to the vehicle. This helps prevent short circuits, protects internal components, and ensures a safe system startup.
2. Before securing the head unit into the dashboard opening, ensure that all basic functions are working properly. This includes testing the speakers (audio output), screen display, camera feeds, USB connections, and other essential features. Confirming functionality before final installation helps avoid the need for disassembly and reinstallation if any issues arise.
