Chapter 31 System Update

Online Update (Over-the-Air Update)

OTA updates automatically download and install system versions released by ATOTO through a network connection, without requiring the user to import any files. This method is suitable for general users to obtain the latest features and optimizations at any time.

Requirements for OTA Update

1.The S8 Lite head unit is connected to a stable Wi-Fi / 4G network

2.The S8 Lite head unit is powered with a stable power supply

3.The S8 Lite head unit has sufficient storage space

OTA Update Steps

Navigation Path: Navigate to Home Screen > App Drawer > System Update App

Step 1: Tap the System Update App icon to enter the update interface. Then tap “System Update,” “MCU Update,” and “CAN Update” to check for new versions. If an available update is detected, the system will automatically prompt you to download and install it. After the update is completed, the system will automatically reboot again.

Note: If the user has not connected the GPS antenna, new version notifications will not be received.

Precautions

1. Do not disconnect the power, turn off the unit, or unplug essential wiring during an OTA update.

2. Keep the S8 Lite head unit connected to the network and ensure it remains powered on throughout the update process.

3. The screen may temporarily turn black or the unit may reboot during the update; this is a normal phenomenon.

4. OTA updates do not affect user data stored on the head unit, but it is still recommended to back up important information in advance.

Chapter 32 FindApps

The FindApps is an exclusive app store designed specifically for ATOTO Android devices. We are dedicated to enriching your driving experience with a wide array of software.

Operation Steps of Using FindApps

Navigation Path: Navigate to Home Screen > APP Drawer > FindApps

Step1: Tap the FindApps icon to launch it.

Step2: On the app page, scroll through the list to find your desired app, then tap Install > Retrieve.

Step3: On the Manage page, scroll through the list to find the app you want to uninstall, manage, or update, and proceed with the desired action.

Chapter 33 Fast Boot

The Fast Boot function is designed to speed up the system’s entry into the main interface after the vehicle is started, significantly reducing boot-up time.

33.1 How Fast Boot Works

1.Low-Power Sleep Mode

(1) Activates approximately 5 minutes after the engine is turned off and the key is removed (or upon opening the driver's door, depending on the car).

(2) Enables the S8 Lite Android head unit’s system to wake up in under 2 seconds with the ACC power signal.

2.Battery Efficiency

(1) Operates on less than 10mA, allowing a typical car battery to last between 160-250 days in this mode.

(2) Automatically transitions to full power-off mode if idle for more than 168 hours (7 days), reducing the battery drain to just 2.5%-4%.

3.Recharging and Automatic Shutdown

(1) Daily driving recharges the battery, preventing the system from an automatic shutdown.

(2) After parking for over 7 days, system start-up will take 20-25 seconds.

4. Proven Reliability

Supported by over 100,000 users.

33.2 Cautions for Fast Boot

(1) To ensure Fast Boot functions correctly, it's crucial to wire the “12v Ignition/ACC” and “12v Constant Power/Battery”correctly in the power harness. For details, please refer to the “Connection” section under “Installation”. (Navigation Path: Navigate to Eproductcare > Car Stereo > S8 Lite > Specific Model: S8 LiteXXX > Installation)

(2) Incorrect wiring may prevent the system from entering sleep mode, leaving the screen on, or interrupting the hibernation process, leading to a 20-30-second restart time.

Common Usage Issue

Issue:

Can the sleep mode on the S8 Lite be disabled? The customer is concerned about battery consumption and would prefer the unit to shut down completely instead of entering sleep mode when ACC is turned off.

Solution:

On the S8 Lite, after the vehicle is turned off, the unit will exit sleep mode and automatically shut down after about 5 minutes. Therefore, there is no need to worry about excessive battery consumption.
