  • More than 300 apps from Google Play Store have been tested installable on ATOTO A6 Series, especially media/entertainment apps and apps in category of "Auto & Vehicles". However, very few apps that are specified only working on phone based Soc chip will not be installable (such as Android Auto).

All the contacts can be searched by manually typing or A-Z filtering and users can add certain contacts to "Favor" list for quick dialing!
  • Easy pairing & connection - 2 steps, finishing within 2-3 seconds!
  • ATOTO A6 Pro models apply latest Qualcomm Bluetooth 5.0 w/ aptX Feature - it could help decode the high quality audio delivered from phones that Bluetooth of which are also supporting aptX coding/decoding technology, and play the music at Wired Quality Sound level, yet wirelessly. Even though the average bluetooth streaming solution is enough for the majority, there is still regret for these hypercritical people (who are more obsessed with wired CD music). Now throw away your AUX cables, external storage, just play the music stored in your phone via Qualcomm Bluetooth 5.0 w/ aptX option;
  • The aptX feature requires the phone side to also support Bluetooth aptX feature to perform perfectly;
  • Media ID3 info(song name, singer and album) will also be synchronized when using Bluetooth A2DP audio streaming, and dynamic sound spectrum displays when music is playing. Just say goodbye to an empty playback screen!
  • Phone signal strength /battery power could be displayed on A6 notification bar!
  • The Bluetooth 2 not only works as Bluetooth tethering internet, but also allows to connect to Bluetooth game pad(for kids in rear seats), Bluetooth OBD2, Bluetooth TPMS, and transferring files between A6 and smartphone is also supported!

    • Builtin EasyConnect app allows users to cast what's displayed on phone to ATOTO screen via USB/WiFi;
    • Latest Toshiba Ultra powerful Pre-amplifier IC, Enjoying Outstanding Listening Experience


      • The pre-amplifier IC applied to ATOTO A6 Standard & Premium version has been the best one we found that could perform so excellent in processing treble, middle & bass audio and get a positive balance.
      • Now the A6 Pro applies newest much more powerful Toshiba preset amplifier IC,which comes with 4x49 Watts BTL Max output & 4x29w RMS output! It means with the conditions of non-distorted audio amplifying & delivering requirements, the RMS 29w power output lets user experience more powerful, more natural music/audio
      • It can drive 2Ω - 8Ω door speaker
      • Latest 178° full-viewing angle IPS display screen, excellent viewing experience


        • ATOTO A6 Pro applies latest 178° full-viewing angle IPS display screen, which helps improve viewing experience in strong daylight, and important app tips such as navigation prompts could be viewed clearer than traditional display screen;
        • In addition, IPS display technology has outstanding color rendition,as well as retaining displaying naturalness

          Highest Compatibility For Vehicle Fit/Installation

          There has been a consensus on the dimension of double din in dash metal case for installation (178mm*100mm/7"x3.94"), But there's no agreement on dimension of the front face-plate part. So lots of users encountered issues /hassles with other 2 din head units when installation dash kits are applied.

          Most installation dash kit brands provide 2 din mounting frame with 174mm*98mm opening (Metra, Scosche, PAC dash kit,etc).

          ATOTO S-A6(Y)27xxx can fit perfectly! No trimming/cutting job is needed!

        • Max 2A Quick Charge - Replenish Phone Battery Power Easily

          Phone battery power may drop quickly, especially when it is streaming audio via Bluetooth, or sharing phone data (WiFi hot spot or BT Tethering) for Android car stereo to access internet, or running EasyConnect app wirelessly.

          Powered by inner PMS IC, ATOTO A6 Premium/Pro can deliver power to smartphone faster than other Android car stereos (500mA - 600mA). Max charging speed is determined by charging protocol from phone, & length or materials of the charging cable.

          2S FAST BOOT

          Fast Boot - Access the system less than 2 seconds

          To speed up the boot time of Android system from 25s to only 2s is never easy. Protecting car battery from draining out,as well as ensuring quick boot available every time you start the engine are the two key essentials. This feature has been tested in more than 40000 pcs of ATOTO products (M4 & A6) and is reliable enough. The inner clock will count and if the vehicle is parked for more than 7 days, it will be automatically powered off to save car battery power.
