Hope this helps someone - I compiled all the information I needed to install my ATOTO A6 Pro, and provided a thorough review. Feel free to ask questions. It was a somewhat complicated install.Materials:

Radio is fast and responsive, just like a smartphone. Screen is crystal clear and sensitive to touch, sharp display resolution (1024x600), bright enough to view even in direct sunlight. Much sharper than Pioneer/Kenwood screens (840x400). Screen brightness is adjustable. Sound output is crystal clear (no amplifier in my setup - and no noticeable distortion even at max volume on my JL Audio Component speakers).
Built in 13 band equalizer with several preset settings (Rock, rap, ect). Equalizer adjustable, but you cannot save your own pre-set settings.
Overall radio seems excellent, does everything I wanted, no bugs or issues to complain about. Future firmware releases could potentially unlock more features. ATOTO does provide firmware updates (to be manually downloaded/installed). External GPS and WIFI antenna included. It will support factory toyota reverse camera and ATOTO dash camera (sold separately). Also enables steering wheel controls.Note: You MUST have Wifi-hotspot available on your phone, otherwise you will not be able to provide a data connection for google maps, apps, ect. I have not found a way around this. Also, be sure you have plenty of data.
There are several versions of the ATOTO available. For a list of differences- see the brochure link below . I went with the A6 pro because it has the best quality screen and amplifier. I opted to exclude the gesture control, seems useless when you have steering wheel controls.
Atoto Radio Brochure
Also note that the newest model has flush “capacitive” buttons (behind the glass), which has a big air gap between the glass and the substrate layers of the display. This can result in a parallax effect on the screen, some users complained about that.
Amazon also offers the previous generation which had physical buttons. I went with the physical buttons version, I think it looks better anyways.Apps:
Full access to the google play app store. Compatible to Torque App for live vehicle information such as RPM, coolant/intake temps, O2 sensor readings, estimated MPG, fault codes, ect. Supports voice activation with Google, Hound, Alexa, and other voice control apps. It doesn’t seem quite as responsive as Siri/Google. I don’t think picture in picture is possible, so if you are using google maps you cannot control your radio/music app by hand (but you can still use steering wheel controls, which gets the job done)Calls/Texting/Searching:
Operating system is Android 6.0 (Marshmallow). You can add additional apps (Alexa, Hound, Pushbullet) to add features such as voice activation of phone calls, pushing text messages, and voice searches. Voice calling works fine, but hands free texting is not an option (I have not found a way around this yet). There is no text messaging “banner or popup” like you would see displayed on a smartphone.
You can use “Headunit Reloaded” if you want to use Android Auto/Apple Carplay on this unit. I tried the free trial of Headunit Reloaded, it seemed very slow/laggy, so I deleted it.The ATOTO has a built in phone call app which syncs your contacts, and allows you to manually select favorite contacts to be displayed on a separate menu.
The app store is useful for a variety of other apps, it can be used just like a smartphone. Add your favorite podcast app, let your passenger watch youtube, netflix, ect. The bottom line is, this radio has a ton of capability, but it will take time to set it up for your needs, just like a smartphone
Additional Features:
Customer Support:
- Add OBD bluetooth Dongle to use torque ap
- Add Atoto Dash camera - dash video’s can be displayed directly on the radio (easy to prove fault in an accident right on the spot). May support other dashcams, but the Atoto 44P2 is plug and play via USB, 1080P resolution at a bargain price.
Seems fairly responsive (12-24 hr delay), somewhat helpful if you are familiar with/educated on your problems. Small language barrier. Based 100% in China.Installation Instructions:
Disclaimer: All modifications performed at your own riskRadio wiring is simple, pretty much color for color between the ATOTO & Metra harness. Use good quality heat shrink connectors or solder if you feel brave enough.
Steering Wheel Controls:
Use the Metra 70-8814 Harness. Follow the wiring below for connecting the Toyota factory harness to the Atoto Harness. There will be some extra wires on the Metra Harness - you can cut and tape those.
- Atoto Steering Wheel Control # + to Toyota PURPLE AND WHITE (middle one) - with 300 ohm resistor
- Atoto BLACK GROUND to Toyota White/Red stripe
- Atoto Steering Wheel Key + to Toyota Yellow/Black line - with 2000 ohm resistor.
Note: You must place two resistors inline (in series) with the #+ and the + wires. These are absolutely necessary because some of the Toyota button resistances are too low to interface with the ATOTO. I used a 300 ohm resistor on the #+ and a 2000 ohm resistor on the + wire. ATOTO customer support also confirmed this is necessary on the Tacoma (and potentially other vehicles as well). You can use pretty much any size resistors within the 200-10000 ohm range, it’s not picky as long as they are different resistances. After that you can program the buttons, fairly straightforward.WIRE #+ 300 RESISTOR #+ WIRE

Youtube Reference - Highly recommend you watch this before doing any wiring:
https://www.youtube.com/watch?v=iIZZAtEcBqk&t=621sThere are multiple ways to wire the camera. If you have a factory backup camera, the factory rearview mirror provides a 6 volt output to power the rearview camera.
Note: Disabling the rearview mirror and using a PAC-39 to power the camera should theoretically provide the clearest picture. However I was still disappointed with the picture quality - it looks a bit fuzzy/grainy on the ATOTO, mostly due to the fact that the factory rearview camera is low resolution. Solder your wires and use a good quality component video cable to achieve maximum video quality.
- If you want the camera in the rearview mirror and on the ATOTO, then you can just tap into the Camera positive and negative wires, run an RCA to the ATOTO backup camera input. This is the simplest method, since you retain your factory power source.
- If you want to disable the rearview mirror and just display on the ATOTO, then follow the wiring below.
Wiring Method #2: Wire a PAC-39 up above the dome light. PAC-39 to provide 6V power to backup camera. Backup camera positive and negative run to the ATOTO backup camera input.
Tape an 18g wire along the RCA cable, use that for reverse input to the ATOTO unit (activates the rearview camera function). Run the RCA from the dome light, down the A-pillar, under the dash to the ATOTO.Rearview Mirror Wiring (factory)
PAC Wiring:
PAC39 White/Red (6V OUTPUT to camera) - connect to toyota shielded cable black wire
PAC39 Black (GROUND) - connect to toyota white/blackPAC39 Twist Red and Blue on the PAC together (12V POWER INPUT) - connect to Toyota small gauge RED Reverse wire at the rearview mirror
Note there are TWO red wires going to rearview mirror one is a constant 12V and the other is 12V only when in reverse (should be a smaller gauge wire). Test your wires before disconnecting anything!)Also connect the reverse wire to that extra wire taped on the RCA, connect other end to ATOTO Reverse wire (pink). In my case, I installed the dash camera at the same time and fed all three wires down into the dash.
You can also use the toyota accessory light green to power the PAC if you want to utilize the backup camera at other times (when driving)
The toyota shielded harness contains the 4 wires going to the reverse camera:
Flush Mount USB Connection:
- Black - 6V output to camera (cut and cap mirror side). Connect pac 6V output (white/red) to black
- Shield (Bare Wires) - Camera ground - connect to PAC39 ground
- White - Camera video negative - connect to RCA shield
- Red - Camera video positive - connect to center pin of RCA
To remove the old aux input, stick your fingers behind the AUX jack inside the dash and pop it out. It’s a tight squeeze.Pop the new USB connection in, and plug into the USB labeled “EZ-connect” (used for data transfer/mirroring).
Note the ATOTO also has a second USB output for a 2A Quick charge. (Quick charge port does not support mirroring)
