More than a car stereo - Install Android Apps,play music online, run online map & get real-time traffic, connect various external devices to expand functions

ATOTO S8 internet access & multiple connections

S8 Ultra provides 2 Methods for Internet Access:

1). Phone's cellular data


  • S8 allows users to connect to the phone's hotspot via 2.4Ghz WiFi or Bluetooth tethering for internet access.
  • Running online maps or streaming music online on Android car stereo do not need high bandwidth(less than 200kb/s), Bluetooth tethering connection is capable of dealing with such demand.
  • Compared with WiFi connection, Bluetooth tethering has lower power consumption, so phone battery will last much longer while Bluetooth tethering is enabled;
  • WiFi connection is easier as it requires only one step - enable your phone's WLAN hotspot, and WiFi connection is finished within 2-4s; Bluetooth connection requires 2 - 3 steps;


2). Built-in 4G Cellular Modem


  • There is a SIM card slot behind the unit, and it only takes Micro size. SIM with Data Plan is not included in the product package.
  • The integrated 4G LTE modem module works with frequency bands supported by most carriers. The supported frequency bands are - 2G (GSM 850, PCS 1900); 3G WCDMA (B1, B2, B5, B8); 4G LTE (B1, B2, B3, B5, B7, B8, B20, B28A, B34, B38, B39, B40, B41);
  • Only carriers who support bands listed above can allow S8 to access the network. Even if the frequency bands in the above list are supported, the operator's communication base station does not cover the places your vehicle stays, S8 will not be able to access it.
  • You can visit Wikipedia to learn more about LTE bands supported by local carriers. International buyers need to check the frequency bands compatibility with your local carriers/operators before placing order.


Install countless Android apps from Google Play Store


  • More than 1000 apps from Google Play Store have been tested installable on ATOTO S8 Series, especially media/entertainment apps and navigation apps in the category of "Auto & Vehicles". Very few app developers may specify devices/system environments that are allowed to install or run their apps, which results in the inability to install or run on any Android car stereos. Netflix is the case, but a specific version of Netflix is pre-installed so that you can still use it on S8;


Versatile Connectivity - The ATOTO S8 Ultra has lots of inputs & outputs customized for working better in a vehicle


  • Connect to a specific USB On dash 1080P DVR camera for video preview & playback;
  • Connect to a specific ATOTO USB TPMS tire pressure monitor system. When one or more tires are under-inflated, it will pop up a prompt warning on the S8 screen, and even emit a prompt tone as a reminder;
  • Connect to a rearview camera with CVBS & HD video signal out for safe parking;
  • Connect to your Android / iOS smartphone via USB/WiFi and using EasyConnection to cast what's displayed on the phone to S8's screen;
  • Connect to your Android / iOS smartphone for running iPhone CarPlay (wired & wireless connection) / Android Auto (wired connection), which seamlessly integrates your smartphone with the S8's built-in display and allow you to make phone calls, access your music, send and receive messages, get directions;
  • Connect to an OBD II Diagnostic Scanner /Engine Code Reader via Bluetooth 2; Compared with single Bluetooth, dual Bluetooth makes communication tasks more balanced and stable between multiple Bluetooth connections.
  • Plug the phone into the dedicated QC 3.0 interface, S8 will charge the phone battery quickly.

Dual Bluetooth chips inside, connectable to more Bluetooth-based devices, customized Qualcomm Bluetooth 5.0 with aptX HD audio codec and voice assistant interface

ATOTO S8 Ultra Android Car Stereo Bluetooth 5.0 aptX


  • The Bluetooth 1 works as Bluetooth hands-free (call/answer) with A2DP streaming audio feature. Contacts/recent records will be synchronized once the smartphone is connected. Supports "Quick Search" and "Add to Favorites" for quick dialing!
  • Built-in Noise Cancellation Technology to help suppress background noise and echo feedback in a hands-free call. You don't have to yell at the car stereo to talk with the other one.
  • ATOTO S8 Ultra applies Qualcomm aptX HD codec, which was designed to answer the growing demand for high-resolution audio. This enhanced codec supports 24-bit music quality over Bluetooth. This means listeners can hear even the smallest details in their music. Even though the average Bluetooth streaming solution is enough for the majority, for these hypercritical people (who are more obsessed with HD audio quality), there is still regret. Now, enjoy wireless HD audio easily with S8 Ultra;
  • aptX Low Latency audio delivers sound in sync with what’s on-screen, reduces delay and improves end-to-end speed of the audio transmission (from 120ms to 40ms!), resulting in high quality, synchronized sound, so you never miss a beat.
  • The aptX HD feature requires the phone side also to support Bluetooth aptX HD to perform correctly; Users can check this on Qualcomm aptX HD official
  • The Bluetooth 2 not only works as Bluetooth tethering internet but also allows to connect to Bluetooth gamepad(for kids in rear seats), Bluetooth OBD2, Bluetooth TPMS, etc.;
  • Because of dual Bluetooth inside, the system allows user to connect up to 3 devices simultaneously(one for audio, two for data communication).
  • The customized Bluetooth in S8 allows to wake up the phone's voice assistant (Siri, Google Assistant) via Bluetooth connection. So users can use a specific button on the screen, steering wheel or ATOTO AC-44F5 wireless remote to send messages, make calls, and control music with your voice. Much safer, much convenient;

ATOTO S8 easy installation

Highest Compatibility For Vehicle Fit /Installation

Currently, the front panel of 7 inch screen aftermarket car stereos has various sizes (178mmx100mm, 178mmx102mm, 180mmx102). However, most of dash mount adapter suppliers mainly provide 174mm x 98mm dashboard opening, many users encountered trouble / annoyance during installation. ATOTO S8 universal double din models use 193mmx97mm size and can fit them perfectly, no cutting / cutting needed! This S8 model is a universal double din car stereo and the extra accessories needed to complete the installation in a specific vehicle are not included and it is the buyer's responsibility to prepare for these (if applicable). Accessories that may be involved include (but are not limited to) dash kit, wiring harness, radio antenna adapter, data interface, etc.

ATOTO S8 comes with single camera based virtual surround view parking feature

HD 720P rearview video display with Virtual Surround View parking feature (single-camera based)

Traditional car stereos can only take and display 400-600 lines CVBS rearview video signal. ATOTO S8 works with a specific HD camera to show HD 720P rearview video quality. S8 Ultra has integrated a special Panoramic Image Stitching algorithm that allows the processing of the image sent from a specific rearview camera and rebuilds a dynamic, virtual, but almost same-size ratio surroundings view. It is quite helpful for drivers to park large vehicles (full-size sedan/SUV, van, light trucks) in a narrow or small space. The specified backup camera (AC-HD03) for Virtual Surround View parking is sold separately.

ATOTO S8 Privacy protection

Personal Privacy Protection without sacrificing convenience

In order to protect Google /Facebook & other SNS accounts from being accessed, S8 has a screen lock option for users to lock the screen when the car (car stereo) is not in their control (Valet Parking, or vehicle taken by others). An additional option (Unlock with Bluetooth) allows user to unlock S8 screen once phone Bluetooth is connected automatically. You do not have to input the password manually to unlock the screen.
