Tracking this info down was a nightmare for me. Hope this is useful to someone.
Requirements:
• Axxess aswc-1 Universal Steering Wheel Control Interface. (link)
• Time and patience.
IMPORTANT: DO NOT use the 3.5mm Female input (SWC IR-WIRELESS Steering Wheel Key Control Port) on the back of the Atoto A6 Pro. This port does not work for some reason.
**Connections to the Car**
1. Download the vehicle specific instructions for your car, as well as the "Axxess Steering Wheel Control Interface Installation Manual" (two different PDFs) from https://axxessinterfaces.com.
2. Follow the vehicle specific instructions to first connect the AWSC-1 to your car.
**Connections to the Radio**
1. The aswc-1 includes a female 3.5mm connector with a brown and brown/white wire coming out. Use this to connect to the Atoto’s Steering Wheel Key(+) and Steering Wheel Key#(+) wires.
2. Connect the "Steering Wheel Key+” wire of the Atoto A6 to the Brown/White wire of Axxess ASWC-1, connect the "Steering WheelKey#+” wire of the Atoto A6 to the Brown wire of the aswc-1
(yes, both of these wires are positive. I don't know who or why, but it works.)
3. Plug the male 3.5 mm jack from the aswc-1, into the female 3.5 mm jack that you wired up in step 2.
4. The ASWC-1 will NOT auto detect the Atoto A6. (don't worry, not a problem)
5. Follow the instructions from page 12 of the "Axxess Steering Wheel Control Interface Installation Manual" to change your radio type.
Change your radio type to "Visteon". (Visteon is radio type 8).
7. At this point you have completed configuring the aswc-1. Next, move on to your radio.
8. From the radio navigate to: Settings>Default settings>Steering wheel program.
9. Once at the screen press "Reset".
10. Then press any key value from the menu, it will begin to flash.
11. Finally press one of the buttons on your steering wheel. The flashing key (from step 10) on your radio will stop flashing, and a triangular symbol will appear on the key. This indicates the key has been successfully programmed.
repeat steps 10 and 11 until you have programmed all the steering wheel control buttons. :good:
first thanks for the guide there is nothing of information of those two wires anywhere.
second, I followed all the steps except the manual programming of the stereo, but use the axxess app to program the module as Visteon but I still can not make it to work, I know that axxess is well connected to the car because it already worked with my previous stereo but honestly I do not know what else I can do to make it work.
ATOTO steering wheel control for cars with resistance circuit
Just wanted to mention that if you vehicle's steering wheel controls is based on a simple resistance circuit, then it can be connected directly to ATOTO with no need for Axxess aswc-1. My vehicle (2011 Subaru WRX) was in this category.
For my vehicle, there are two wires in the harness and the resistance between these two wires will change depending on which SWC button is pressed on the steering wheel. Unfortunately, the ATOTO documentation is dead wrong how to hook this up. The manual says that if your vehicle has two wires, you should connect the two wires from the vehicle to the "Steering WheelKey#+” and "Steering WheelKey+” wires. That doesn't work. Instead you should connect one of the vehicle wires to chassis ground and the other vehicle wire to either of the ATOTO "Steering WheelKey" wires. I think the ATOTO wires are both labeled as "+" because they assume the vehicle SWC will provide a path to ground. Hope this information helps someone else.
Thanks a lot for your sharing! Really helpful!

On the Atoto a6 there is a Steering Wheel Key + (Orange wire) and a Steering Wheel Key# + (Brown, Black Stripe).
On my Metra harness there is a Steering Wheel 1 (Green), Steering Wheel 2 (Blue), 12v (Red) and Ground (Black). All for the Steering controls.
This is on my 11 WRX.

Can you give a link to the Metra harness you have? The 2011 WRX steering wheel controls have 2 or 3 wires depending on your car's options, so having 4 steering wheel wires on the Metra harness seems strange. I'll paste one of the wiring diagrams here, guessing at your car's options. If you have trouble pasting a link to a Metra part like 70-8901 , just add some spaces onto the URL to make it look like plain text.
Also it would help to know if your 2011 WRX came originally from the factory with a non-bluetooth radio, bluetooth radio, or with the Navigation. The important point here is whether your steering wheel has just the Vol+/Vol-/Mode/Seek button cluster or if you also have the other cluster for controlling the bluetooth phone.
My guess is that you should connect Metra SteeringWheel1 to ATOTO Steering_Wheel_Key+, connect Metra SteeringWheel2 to Chassis Ground, and leave the any other steering wheel specific wires on your Metra harness unconnected since ATOTO doesnt need those. This is just a guess without the other info that I requested.
My bad. It is an "upgraded metra". It won't let me post a link. From auto harness house part AHH-70-7552
My cars a limited no nav. So it has bluetooth.

OK, so given that you have harness AHH-70-7552, then you should connect Metra SteeringWheel1 to ATOTO Steering_Wheel_Key+; connect Metra SteeringWheel2 to ATOTO Steering Wheel Key#+; leave the Metra SWC +12 and ground wires unconnected (ATOTO doesnt need those). The "third" common wire from your vehicle's SWC will be correctly connected by ground by the harness itself, as is noted in the AH-70-7552 product page:
*Pin 14 is grounded in the harness for the convenience of the installer. If this connection is not desired, cut the wire that connects between pin 14 and pin 10

BTW, you might find this AE64 page useful for details on the pinouts for your subaru's 20-pin connector.
On a separate topic, are you connecting a back-up camera to the ATOTO? Noticed that your Metra harness doesnt have the reverse gear signal.
I was going to eventually and just run a wire from the reverse sensor wire to the units harness

Yes, that's what I did on my install and what I would recommend. The ATOTO has a "feature" where it will disable playback of videos unless the parking brake is set, but that feature is disabled by default. There is no particular reason to connect the parking brake wire to the ATOTO unless you plan on enabling that feature.
Atoto swc
Thank you for your tip, my car Mitsubishi Pajero dakar has 2 wires with diferent resisteses, i conected 1 cable from the car to ATOTO and the second cable of the car to ATOTO AND GROUND toghether, that was the only way that worked... if i leave the second cable of atoto without ground it do not work..
Outlander 2015 Problem
Hi All !
I followed your instructions.
I have a Outlander 2015 and a ATOTO Pro A6.
After configuring the AWSC-1, only two buttons on the steering wheel work in the mapping panel (Volume up and skip right) no other wheel button is recongnized by ATOTO
I tried to swap the wires from the male jack connected to Steering key and key# with no luck.
Anybody encountered the same problem ?
Thank you
help what colour

Did your 2011 Subaru Forester come from the factory with Navigation? If not, then does your steering wheel one cluster of SWC buttons (Vol+,Vol-, Seek+, Seek-, Mode, Mute) or does it also have the second cluster of SWC buttons for controlling Bluetooth phone? These questions affects the color and location of the wires you'll be looking for.
It has volume +&-

OK, Take that to mean your 2011 Subaru Forester did not come with factory navigation and does not have the Bluetooth steering wheel buttons. In that case, you are looking for the following two wires on your car:
Yellow wire: Connected to pin 14 of your 20-pin Subaru audio connector.
LightGreen with red stripe: Connected to pin 4 of the 20-pin Subaru audio connector.
Refer to pics and pinouts of the 20-pin Subaru connector. Connect one of the above two Subaru wires (either one) to ground. Connect the remaining Subaru wire to ATOTO orange-black steering wheel key (+).
Leave the ATOTO brown-black steering wheel key #(+) unconnected. This worked for me, but others had reported that they needed to connect the steering wheel key #(+) to ground, so you could try that if needed.
Thank you, I will give it a try,
Since you are familiar any idea the best place for finding a reverse light wire easy to get to.

On 2011 Subaru Forester with factory navigation, that wire (a brown wire with yellow stripe) would be brought out to one of the navigation connectors. Don't know if that wire is accessible in your vehicle's instrument panel harness or not.
2015 Honda Fit
I've got the AWSC-01 connected to the HDCC-02 harness. The module will sense my buttons for setup but I cannot get it to work with the head unit. The head unit will detect a button press when the module ends it's setup mode on boot though. I've got it hooked up as described using the wires through the HDCC-02 harness. I even tried grounding each wire and it didn't make a difference.
According to another user they had to buy a $100 adapter to get it to work. I really don't want to pay $100 for steering wheel buttons.
Help would be appreciated.
2014 WRX l, no nav, bluetooth.
So my Metra harness did not come with steering wheel pins (4, 13, 14) can I just bypass the harness and hook it up straight from the A6 to the cars wires?
Hi all !
I'm starting a new thread because I did not find a lot of information about ATOTO A6 Pro and steering wheel controls.
I have a outlander 2015 and Im trying to use the steering wheel controls on the ATOTO using a aswc-1. I plugged the brown wire and brown white of the aswc to the two swc wires on the ATOTO.
The aswc auto detects the car but not the radio. I tried pioneer and Visteon but only two buttons work (vol up and seek forward).
I also tried to switch the two wires. No luck.
Anybody had success configuring the pro version ? Which radio type did you use ?
Tried to contact Atoto support but no news from them yet.
Thank you !
Hi, me too I need an interface between sec and tesla style android radio. Let me know if it will work

Problem solved !
I finally found a solution to my problem.
I got rid of the aswc-1
I connected pin 9 from the 20 pin power harness to the steering wheel key + (not the #) of the ATOTO pro and I also connect pin 19 to ground.
That's it !
After that I configured the different associations between keys and action in
Settings general settings steering wheel on ATOTO.
Hope it helps
Merry xmas to all. !!!

Lolo - how did you identify which wire to attach to the Atoto, and which to ground?
I have an issue with Atoto A6 and steering wheel controls as well. The information on this subject is all over the place.
I have a 2010 Prius with steering wheel control built in, but the suggestion was that I could not use Atoto's SWC without an Axxess ASCW-1. So I bought that, and a wiring harness for the Atoto to the Prius, so I wouldn't have to wire anything myself.
So, the radio is working fine... but the steering wheel control is completely non-operative. I'm using only four wires on the Axxess - red, black, green orange (or brown?) and green black. Wiring just the power and ground (red and black) I got a slowly alternating red/green on the Axxess. Wiring to the SWC1 and ground gave me a solid green on the Axxess (the wire harness SWC2 is an empty socket). Even with the solid green, when attempting to program the SWC in the Atoto menus results in no response. I'm sure the wiring is janky, of course, because the information is so sparse and at times conflicting.
So... do I even NEED the Axxess on an Atoto A6 and the 10-15 Prius? If I don't need it, what's the process for hooking up the stereo alone? This is making me... unhappy. LOL.

I'm not sure about the 10-15 Prius, but you can check with a multimeter. If you only have 1 or 2 SWC wires, just check resistance between the wire(s) and ground when you press buttons. Resistive SWC just use different resistances for each button press (which you'll see in Ohms). If they're resistive, no adapter necessary. Just splice and go.

I figured it out by going back to my early years as an IT tech.
There were FOUR separate wiring harnesses the original Prius II (2010, non-JBL) had connected to the factory Matsushita stereo. I bought an Axxess ASWC-1 and a wiring harness specifically for the Atoto A6 to a Prius. The new harness only used TWO of the FOUR harnesses (an 8 pin and a 12 pin, unused were a 20 pin and a 10 pin). The problem is that the wiring harness had two SWC wires, and neither was *actually* going to the factory SWC. I couldn't diagnose which wires were the SWC... so like an IT tech, I hooked the old radio up and just started eliminating the harnesses one at a time to figure out which one had the SWC wires.
Lots of web searching told me I might be looking for a pink and red wire, the process above *confirmed* that the harness with the pink and red wires was the harness that included the SWC. SO. I cut the pink and red and hand-wired them to the SWC1 and 2 of the Atoto HU (ignoring the Axxess ASWC-1 completely)... and it worked. Went into the Android default settings, programmed the Keys to Vol + and - and FFD/Rew, and then it completely worked. What's more, I can return the Axxess ASWC-1 to Amazon and have one less aftermarket part jammed into my dash.
I put all this information here so if anybody has a similar Prius they want to upgrade they can see my experience. If you have a Prius 2010-2015 and you want to upgrade the factory radio, you can do it with an Atoto A6 and retain your SWC without any adapters. Yay!

Did you end up going with Atoto. I am considered one and did not find much information!
