When I connect my Android smartphone to any USB of the device, it's charging it but it doesn't recognize the phone as a storage device to access data. Also phone gives a pop up that the device it's connect do can't access its media. Is this normal? I also got quick charge off.

Charging problem through the dongle for Android Auto or Carplay

Hi All,

I installed an ATOTO A6 Pro in my wife's car about a week ago. I noticed that when she uses her phone through the dongle with CarPlay, the phone does not get charged.

I wrote to ATOTO support about this and they said that the phone must be using more energy than the unit can provide through the dongle. They also said that using the "Quick Charge" USB output wouldn't help because when the dongle is connected, it switches to "Standard Charge" mode automatically.

Has anyone else experienced this? Bit of a deal killer for the wifey...

Subwoofer issues

I installed an A6 Pro without gestures a week ago. I can't seem to get any decent volume out of my subwoofer. I've got a 200 watt Kicker amp with a 12" subwoofer in my trunk. I've adjusted the gain with a 40hz tone. Even if I set the subwoofer setting to manual and turn the volume up to 40, I hardly get any output to the point that if I turn the subwoofer output off I barely hear the difference in the interior of the car. I've even turned on bass boost on the amp and loudness on A6.

My last HU had a separate sub volume I could adjust to get a nice deep bass sound, but this is ridiculous. I did use an RCA Y adapter to go from the A6 to the stereo inputs on my amp, although the sub of course is wired for mono. Ideas?

My system with an A6 Pro with an addition of a preamp

I’ve been watching this post for some time. I own an A6 Pro and really like it. I haven’t had any significant issues after the 9.5 update and hope a few things, that you all mention, do get updated.

I would like to add a significant upgrade I made which ten folded the A6’s sound and abilities. I added an Expert Electronics PX8.2 8 way preamp with IPhone app control. I mainly wanted it because of time delay, better crossovers, parametric EQs and precise gains - plus other cool features. It might go over your budget but it really gives the A6 razor sharp precision and still falls way under a name brand. It’s sound is much better than a name brand with the Expert pre amp in the mix.

For those not familiar with time delay, it was the feature I really wanted that sold me to the Expert. I was in competition in the 90s and remember getting in a vehicle with calibrated time delay. The notice was apparent immediately. Time delay insures your sound reaches your left and right ear at exactly the same time. This creates transparency to the music and offers realism. This is done by entering the exact measurements of all your speakers to your ears in 10mm increments. You then program these measurements into the Expert PX8.2 using your iPhone app or you can also download the app into your A6 regular or pro to control your PX8.2. My system hit under budget and sounds similarly to my competition system from years ago. I am running Rockford amps but plan to go to soundstream high end amps. I know I’ll get better headroom and a cleaner soundstage with soundstream amps vs Rockford. The Rockford class D are excellent though.

They ship super fast!!! Had it in like 5 days to Florida!! Straight from Brazil! they are out of stock at the time of this post , which doesn’t surprise me, but hopefully they re stock soon. There are other similar models but this worked best for me.

I have had one issue I’m trying to work through. Certain usb sticks won’t recognize. It only likes slower cheap sticks. Any input would be appreciated. As writing this, I just thought I should try turning of the fast charge setting for USB. Maybe having this on is affecting compatibility of the usb sticks.

I just got my Atoto device and using Google assistant t doesn’t play auto play songs on Spotify. If I tell the google assistant to “play Ed Sheeran on Spotify” It just opens the Spotify app without playing.

Anyone knows how to get the Google assistant to actually play the song on Spotify on the Atoto A6? Thanks

Atoto A6 Pro, NO POWER :(

I have owned an Atoto A6 Pro since March and it has been great but today, suddenly, when I started my car, the screen wouldnt come on, blank, no sound, no flicker, nothing.

I tried turning it on and off, turning the car on and off, hit the reset button on the outside of the unit, pulled the unit out and there was nothing unplugged.

Just stopped working!? *shrug*

Anyone seen this happen before?

Have you checked the car fuse and the fuse on the back of the radio?
[Android Head-Units] imogenheap:
I downloaded the Google assistant app from the play store. Does Google Assistant work to play music on Spotify on your Atoto unit?
[Android Head-Units] djdavid:
Yes it works.

Today I try again.

Have you the premium account on Spotify?
[Android Head-Units] moti_r:
Thanks for the info.

I just ordered an A6 Pro last week (hope to get it next week) and I'm actually quite concerned about the sound quality. Going to connect it to an external amp.

How did you connect it to the preamp? Using the RCA out?

Have you compared its RCA out to a high-end head unit? Is it the same quality?

I was thinking about getting a USB DAC (Dragonfly black maybe?) to bypass the A6 Pro's internal DAC.

Has anyone done that successfully?
[Android Head-Units] imogenheap:
Yes, I have the premium Spotify account. Do you need to press the Google Assistant app to activate it or does google assistant respond to you saying “ok Google”?
[Android Head-Units] djdavid:
Yes you need to press the Google Assistant app.

It don't recognize the voice.

I just tried and it worked, it open Spotify and the requested song.

I prefer using a multimeter continuity check but you can usually see a blown fluse.
[Android Head-Units] cartainment:
That's concerning. I've recently installed the A6 Pro and I'm loving it so far, I hope issues won't start popping up cause it was also bit tricky to install it in my case. Please update us with what ATOTO says about the issue.

Do we have any kind of warranty in case sh@t happens?

I think audio quality is pretty decent as it is. Haven't got the chance to experiment much with the settings but it seems very decent for a chinese android h.u.

Turn Screen Off while in usage

Also, is there any way to turn screen off while the unit is still on? (like when listening to music?). I know that you can use the stand-by feature but this will still keep the display on so I would like to look for a way to turn if off in order to "help" it a little bit. If not, is there any way to replace the stock screensaver with something that moves (just to keep playing around with the pixels, however I guess IPS displays don't suffer from burn-ins but the issue of the guy above got me concerned)

Atoto A6 Pro (A6YVW721PRB) - ROOT & ROMS

Hello XDA fam!

Has been years since I have posted/resourced XDA. Am glad to be back.. :o …..life - women - work - you all know the drill.

With that being said, I have just purchased a new Atoto A6 Pro (A6YVW721PRB) Plug and Play Vehicle specific model for my 2012 VW Jetta 2.5L.

I am noticing after many reviews and online sources that I should look at rooting and flashing a new rom onto this HU as the stock one is well, should I say - garbage.

It is stock android 6 as I know, but am wondering if this can be flashed into android 8 or 9? Also, if so; what ROMS would be recommended for this unit?

ANY information/links would be greatly appreciated.

:cowboy::good::D
[Android Head-Units] moti_r:
Hey,

I just bought the same unit for VW, hope to get it next week and install.

My main concern is the sound quality. Was hoping to be able to connect a USB DAC but I now read it might not be possible with this HU. Cross my fingers and hope the audio quality will be good enough out of the box.

What do you hope to achieve by rooting?

AFAIU you can overcome the ugly UX by using car dedicated launchers, like CarWebGuru.

Other roms will probably not be a perfect fit, and you'll lose some of the benefits of the atoto, like double bluetooth pairing and aptx support (which is what made me buy it in the first place).

Anything critical that is worth the new rom efforts?
[Android Head-Units] forumsnowsoldier:
Nothing critical I would say, I'm sounding with the stock VW audio so I'm not worried about subwoofers or anything aftermarket. Just looking to maximize performance, really. Navi (GM/Waze) - Radio - BT (Spotify) would be the major usage for me. I honestly just want the unit to run as smoothly/quickly as possible with an intuitive interface, which is user friendly for I, but also for front passengers. Customization is always key as well. Looking for options is all, I suppose. I swear I'm not a perfectionist. ;)

---------- Post added at 09:00 AM ---------- Previous post was at 08:34 AM ----------

If I do look at scrapping the rooting/rom method, what launchers would you think are worth looking at asides CWG.

I guess the main reason for considering some R&R is to steer away from Android 6. There must be a better reason Atoto are using it on these high end models other then its fluidity? Any input on this?

Cheers
[Android Head-Units] moti_r:
AFAIK there's no major difference between Android 6 and 7/8 when it comes to auto. The big leap was for 6.

Also, I read somewhere that many of the allegedly Android 8/9 units are actually 6 with tweaked versions, they are not authentically 9. Not sure about that, but read it in multiple places.

Personally I don't think the version is important at all, as long as the system is performing well and you maintain compatibility with the major important apps.

Two other launchers I found:

https://play.google.com/store/apps/details?id=altergames.carlauncher&hl=en

https://play.google.com/store/apps/details?id=org.kustom.widget&hl=en

(the 2nd one is not a launcher, but it will allow you to customize the stock launcher with nice widgets).

Will give all 3 of them a try when I have the HU and see what sticks.

Also, headunit reloaded is worth checking out, as it may provide you with Android Auto capabilities. I have a feeling this might eventually be 90% of what I'll do with the HU.
[Android Head-Units] cartainment:
Don't worry too much about the audio. I'm with same speakers as before (previously had a pioneer 1-din h.u) and without an amp, and the audio is pretty good. It's same as before if not bit better and louder. Unlike other chinese head units, a6 pro seems to be pretty alright for audio.

By the way, anyone knows any way to be able to receive notifications from your phone to the head unit via bluetooth or something? I know Android Auto can do it, but is it still possible without it?
[Android Head-Units] forumsnowsoldier:
Looking foward to hearing back on the results. I will also do the same.
[Android Head-Units] nosympathy:
Anyone have any luck with getting to a recovery of any kind? Their support has been terrible.

After updating apps my unit would only boot to the initial ATOTO black and white screen and reboot every 1 minute or so. They told me the steering wheel controller can do a recovery so I got that. Followed the recommendation from them. Press Hangup once, Answer twice and microphone 3 times. I can see the unit reset, but it's the same as if I do a pinhole reset.

It's not restoring factory defaults as they led me to believe as the button lights are still the custom color I set.

There has to be a way to force the unit to restore, I just can't figure it out.
[Android Head-Units] eclipseturbo99:
You would want to just use the front stage set of RCA outs. The PX8.2 takes 2 ins and gives you 8 outs all up to 9 volt which will full drive any amplifier so you’ll get all the wattage it provides. Even without the PX8.2, an A6 Pro has a clean preamp and easily compared to any high end unit. I ran the best head unit money could buy when I competed so my ears are tuned to good quality and I would have returned the A6 in a heartbeat if it didn’t live up to my standard. Don’t let the low price fool you. I do worry about longevity as I see users reporting issues here too soon into their purchases.

It does fall short in some minor areas but sound isn’t one of them. It does fall short with output voltage. To get the most headroom and lowest harmonic distortion, you would want to add a good preamp line booster or a full preamp like the Expert PX8.2. 9 volts would be more than adequate. Standard preamp boosters are rather inexpensive but most only use 1 channel pair and you would need 3 for a 5 channel setup. I always used preamp boosters - I sold them to buy the PX8.2 and very glad I did. So I still would highly recommend a PX8.2 if your running a 5 channel or more setup because it costs less than an audio control preamp booster. The higher voltage in the preamp stage will send a cleaner noise free signal to the amplifiers allow the gains to be turned down. I run a 300 amp alternator and before the PX8.2 I had a decent amount of alternator whine and after adding a strong preamp voltage, its gone. It’s mainly because before adding the PX8.2 I ran the gains on the amps much higher which introduced noise. Some amps use strong internal preamp stages and do not require a booster. You’ll know if your cranking your gains all the way up and the system still runs quiet with heavy hiss or alternator noise. I run Rockford, right now, and they are known for low gains. Once boosted they rock very clean.

One more plus the PX8.2 gives is the balance and fade is much more accurate (one main reason I wanted it). You do this through the assigned channels gain. So basically it has greater stepping resolution. With the A6, by itself, I found trying to balance the channels to achieve a perfect wrapped soundstage either over shot (too far right) or under shot (too far left) the soundstage. I couldn’t get that perfectly balanced center soundstage to the driver listening position. With the PX8.2’s fine gain resolution, you can get a very defined soundstage perfectly aligned center stage without going too far left or right. The drawback is you’d have to fire up the app make quick adjustments

Thanks for the info about the audio!

Re notifications, take a look at pushbullet. I think it might be what you're looking for.

Thanks a lot for the informative reply! If you use that kind of equipment and say the quality is on par with pro audio, I'm much less concerned!

Can't wait to get my hands on the unit already and have it installed.

Strange how the voltage is so low. They claim to have 4V out (when others stick to lower figures). I'll surely give it a try and if there's too much line noise, I'll try amplifying it through something like the PX8.2.

Might also consider a DAC, to be prepared for another unit, in case atoto turns out to be too buggy or unreliable. The latest Joying seem to have SPDIF digital out. Paired with a good DAC, it means you can literally put aside all the audio quality issues. With a proper DAC you can also eliminate any line noise, since you can use a long SPDIF cable and have the D2A done near the amps.

Hope I won't have to go there, though. Atoto seems like a great unit.

I used Pushbullet for several years to sync sms and other notifications.

Right now I am using Pulse for sms.
[Android Head-Units] eclipseturbo99:
I’d say 4v for many applications should be fine. I believe it’s a bloated figure or possibly a peak figure and not an RMS figure. There aren’t many agencies guarding the figures of electronics these days. One reason I like Rockford amps. They claim 400 watts RMS but I get a verification card showing the amp hit 485 watts RMS. So in this case they under estimate their product showing quality. But on the same note, Rockford’s input stage is power hungry and expecting high volt outputs. I remember my Soundstream amps were happy with 2.5volts! So it’s an equipment thing when it comes to volts. I plan to switch back to Soundstream in the next 6 months.

What an A6 allows is more budget. I intended to add a 1/3 octave audio control EQ, a preamp, external amps, and lastly, a high definition digital audio player. I did end up with way more with the A6 because of its ability to run apps and it’s interface and it is like having a mini computer and car audio in one a plus other non android head units can’t do.

Very interesting!! I have messed around with DACs and you are correct. One reason I want to go to a High Resolution audio player in my setup and also convert all my CDs to high definition lossless FLAC format. I have a secret app I’ll share in another post. And this app works with the A6!

If you get the 9.52 firmware update, you won’t find too many reasons to dislike the A6 but the SPIDF output of a joying is very interesting and in a class of its own. I will be reading on that because it does fall in line with my research into high resolution audio. Since high resolution audio is new to me, I cannot believe the sound quality of some samples I have found on the net. And awesomely enough, the A6 played them!!!! that is a good test as there aren’t too many units that can play the files due to hardware limitations. Cool right!!?

Atoto A6 FM antenna connector

Just noticed my existing car antenna won't fit into the back of the head unit. The connectors aren't compatible.

What type of connector is on the back of the A6 for radio reception?

I have a subaru 2014 outback. Would appreciate if someone posted a link of what I need to purchase.

Hey I installed The ATOTO A6 Pro into my 2015 Subaru Legacy. Perhaps this part can help.

I used this part:

Best Kit Antenna Adapter - aftermarket radio to OEM antenna 2010-2019 Lexus/Toyota/Subaru/Scion

Just copy and paste on Amazon. I cannot include a link due to new user link restrictions.

You can enter your vehicle info on Crutchfield if you want a list of compatible parts for a aftermarket installation.

Honestly though I never use my radio on my Atoto. I only use bluetooth through music on my phone or through downloaded music on the Atoto. If you mostly use your phone for music then you can just skip retaining your radio to make things easier.

Word! I actually have one of the very first Rockford Punch amps (the trapezoid figure), bought it something like 20 years ago and it still rocks as new. I remember being astonished by the actual measurements specified on the card that came with it. Amazing hardware.

In my current setup it is directly connected to a Pioneer HU that outs 2v - and I get zero line noise. It's a VW Tiguan, so not too long of an RCA cable to the trunk.

Indeed, great results. Although if you aim for FLAC I guess it should be very easy to decode and play, as it's completely lossless so very light compression. Maybe more sophisticated multi-channel stuff is more difficult to decode, but I'd try to focus my search on finding the right software.
[Android Head-Units] nimbus22:
Thanks for your assistance.

I bought this radio refurbished from a reseller on ebay. He seems to be selling lots of new and refurbished units.

The confusion is that there seems to have a "pin" in the antenna receptacle. Perhaps this came out of a defective antenna cable that was previous plugged in.

So the input looked non-standard. I pulled the pin out and everything seems to work as it should. I can now plug in a standard antenna. Still waiting for a mounting kit before I plug everything in and see if I can get radio stations.

So I checked the fuse on the deck, as suggested and its not burnt out (at least it didnt look burnt out).

I am in the process of contacting the manufacturer, wondering if anyone has any other suggestions?

:(
[Android Head-Units] voigts:
I didn't get any replies about this here, but after some research, it seems that this HU just isn't putting out enough voltage to my Kicker amp for my sub. I installed a PAC LD-10 inline booster and now the sub is working nicely. I'm also going to install a PAC LC-1 so I can adjust the sub on the fly. It's a pain that this unit doesn't have a built in sub volume control, but at least for the $35 or so it's costing I found a workaround.

---------- Post added at 09:58 AM ---------- Previous post was at 09:55 AM ----------

Did u also check the fuse in your car fuse panel?
[Android Head-Units] voigts:
What you really need to do is use a multimeter to check both the HU fuse and the car panel fuse and then probe and verify you are getting 12v to both the yellow 12v constant wire and the 12v red accessory wire (when the ignition is on). If the fuses are good and you have voltage to the HU, the unit is bad. You can easily Google how to do this if you aren't multimeter savvy.

I have several questions.

1. Can I change the volume buttons on the unit itself

2. Is it possible to change the language of the google maps to my native language

3. How do I customize SWC, I paired the buttons with functions but those functions are too limited.

When I press call button on SW, the unit does nothing, so I assume it can only pick up when called.

What I want is I press call and then contacts opens up and I can browse through those using another button etc.

How can I modify these things so I can possibly write a script for this. (and voice thing seems to not work at all)

The stock radio app is kind of clunky. When I add a new station to the radio. It shows up at the end of the existing stations. For example, my last station is 107.9 and is p6. When I add 103.3 it becomes p7. So the stations become out of order.

Is there a way to insert, drag, or replace a station? I can't drag the new station between stations. I tried swiping up, down, left, right but didn't see any new options/menus.

I can delete everything and create the stations in sequence but didn't know if there was an easier way to accomplish the same thing.
[Android Head-Units] ArghMonkey:
When my deck was working I tried researching who made the radio app it comes with, no luck. You can download other terrestrial radio apps but its hard because any search for android radio apps, almost entirely comes up with apps that need internet access and dont work through antenna.
[Android Head-Units] moti_r:
I don't have it installed yet so can't play with it but - when you long press a button, does it store the current station? (like stock units usually do)

If yes, then why won't you use one of the buttons as a temp transfer button?

Meaning - to switch buttons 1 and 3, you first press 1, then long press 6 (to store 1 in 6), then press 3, then long press 1, then press 6, then long press 3.

Hope I'm clear :)
