I can answer for I40 and the only way to get a descent Bluetooth is to modify the HU according
to the specific thread in this forum. Both HU's carry the same problem.
Be careful when you order to get the correct screen ie. 1024. They sometimes specify it as optional.
Also verify if you have a factory amplifier. If you have, you need another loom and an analog/SPDIF box.
They are cheap compared to the big guy's, so don't expect miracles. They still work.
I've four units for different cars similar to yours.

Can you point out the thread with the HU modification that improves Bluetooth?
The original Hyundai amplifier only takes spdif as an input? Intresting i dont see other i30 owners which use an android HU mention that.
You are right on the optional 1024 (usually extra 25$).
Iam most intrested not in the bluetooth mobile -> head unit connection but more in getting the audio from the original mic (just above the drivers head) connected to the HU. I feel this way i have less of the aftermarked look (additional mic) and also better audio since the original mic is pretty much in the perfect spot.
I guess i can solder whatever connection the original mic has to my headunit. But there might electrical issues or the mic cable be part of some strange car bus system which will it make hard to figure outand connect.

I don't have a hyundai, but I've put aftermarket units in 2 different cars w/ mics and both had the same problem - they are active mics that have noise cancelling & can't be used w/ these HUs. BUT, you can still easily disconnect the microphone from where it is located and put the aftermarket external mic in its place. My car is a 2014 mazda 6, and my OEM mic was in my overhead where my dome lights are. The panel was held in by 2 screws where the sunglasses drop down. I drop those 2 screws, disconnect the mic from its connector, and pull the mic out (it had some weak adhesive around it, very easy to take out). I then ran my external mic up my a-pillar and mounted it exactly where my factory mic was located. Sound quality is very good, everyone can still hear me okay. and everything looks stock.
Just buy a unit w/o BT issues (avoid MTCB units unless they have fixed this... others seem okay).

Are the units in my original post MTCB units?
What is the reason the active noise canceling microphones can not be used?

I didn't check your links so you'll have to check for yourself. An active mic will need to be powered, so you'll need to know the correct voltage and supply it somehow. I doubt it's 12V that you can use directly from the unit but you never know. Read it with a meter.
I guess theoretically you could make it work in that case.

Xtrons and Volvo

Hi everyone, I’m new to this forum. I know a bit about Volvo (the older ones!), and Volvo head units, but not about Chinese Android head units.
I’m considering replacing the aging head unit of my (also aging!) 2002 Volvo V70. The head unit is a simple HU 603, so no Dolby, center speaker or extra amplifier. I’m looking at Xtrons TA702P (quad core) or TB706PL (octa core). I prefer a 7 inch touch screen, no knobs, no DVD. But navi should be good, as would radio. Music I can play through usb. And my Elephone S7 (Android 7.1) phone should mirror on the unit if possible.
Other functions like back up camera or steering wheel control are not important to me.
I know how to take the HU 603 out. I know I need an adapter harness to connect with the new unit. And a fascia adapter. All that is available.
My questions:
Xtrons has many car/model specific head units (not for Volvo). They have Canbus decoders supplied with the unit. Not so for the TA702P or the TB706PL. Will that give problems? (The answer from the ebay seller is somewhat useless: ‘Both the TB706PL and the TL702P does not come with the canbus so that you just ignore it.’) Anyone has experience with this?
How are user experiences with these modern Xtrons units? I know, ‘you get what you pay for’, I know that. But still, worth the money?
Units from Kenwood or Pioneer are other options, but again, is it worth it?
Thanks!

Hi there
I own and drive a V70 from 2006. I have replaced the original HU with a SONY 2 DIN unit (XAV-V630BT). This unit has great sound. I also swapped the speakers to JBL. It is totally worth it.
I have a CANbus to resistor unit. This makes it possible to use the steering wheel buttons.
Right now i am testing a Android HU. Unfortunately i have bought the wrong one. The unit is full of bad design choices. The sound integration in the unit is bad. I think that radio, BLUETOOTH and AUX sound runs directly to the sound processor. This means that when the Android unit plays a sound, the sound from the other units are turned off. In my opinion the other source should just fade a little.

Hi there
As said, I don't need steering wheel controls, my steering wheel doesn't even have the buttons. Must have been a cheapskate first owner!
Does this mean the Canbus only affects steering wheel control? So ignoring Canbus (no resistor as in your case), will give no problems?
And yes, by now I've found out Android units may not have the best sound quality. Or radio reception.

Hello from Michigan

i'm new to the forum but have been lurking and reading up for quite a while on these android head units.
I need to replace the head unit in my 2009 Subaru Forester. I kind of a gadget freak, so these android units caught my eye. I was interested in the DSP units from androidautoshop.com but they warned me away from them and recommended their FX8 units (though they didn't really say why except that they were better quality).
The option I was looking at before the DSP unit was a new XTRONS unit which I could get from amazon. They seem to be well regarded from what I've read and the sound quality sounds like it's pretty good with the new amp chips they are using. Now just the other day I ran across a Dasaita unit on amazon that is specific fit for my vehicle so it wouldn't need an installation kit and BONUS has a 9" screen!
Does anyone have any insight on these units? If I go with an android unit it's going to be to satisfy my tech geek so I'm going to want to be able to customize it.
I need it to have good sound. Doesn't have to be audiophile quality, but good.
Decent to good FM reception.
good connection for Bluetooth (i've heard in particular that some of these units have both connection and sound quality issues with bluetooth)
ability to connect to an ODBII sensor for my car. One that I choose, not dictated to me by the head unit company prefereably.
ability to connect to an aftermarket rear view camera.
able to use Waze and Google maps. preferably with audible directions. also offline mapping for those occasions when I don't have a cell connection.
Ideally I would be connecting these direct to speakers, with the possiblity of adding external amplification down the road.
AndroidAutoShop.com FX8 - I have concerns about them and they don't really say much about why this unit is the best.
XTRONS - seems to be popular from what i've read, though i'm not sure about the bluetooth
Dasaita - love the look of the 9" screen with no ugly install kit. Quite a bit more expensive but possibly worth it? I just can't find much info about these. I think I read somewhere on this site that they were pretty good, but I don't know where and it wasn't about this specific unit.
I'm not allowed to post links to the 3 units above yet, but the first one is on androidautoshop and the last 2 are readily available on Amazon.
Are any of these a good choice for me? or possibly a different recommendation? or should I just forget it and go with a higher end Kenwood or Pioneer head unit with Android Auto and use an HDMI for any video needs? I'm not against tinkering and these seem like a really cool option (possibly saving money over traditional head untis as well) but I don't want to get a giant headache that just never works right.
any help from you guys is greatly appreciated.

Help: Junsun V1 Pro + Audi A3 8P

Hi!
I got an Audi A3 8P from 2010 and installed this HU. Everything is working, Android auto / radio / GPS / canbus / OBD, the "only" problem is the audio quality is horrendous. I was expecting it to be worst than the concert radio but it is really bad to the point I'm thinking about returning the head unit. I want to try to improve it before returning it because I was in a friend's car with the same head unit and the sound quality was miles away. I'm pretty sure the problem is hardware/connections. I read somewhere that some Audis have rear speakers amplified and front speakers not amplified. I'm not sure if my car has this configuration but that can be related to the problem.
What is happening is that the sound feels like someone is pushing the gain to the extreme. High/mid frequencies are very uncomfortable and the low frequencies are almost non-existent. I feel like the 3 speakers from the front are being pushed hard and the 2 front door speakers are very low. I saw a video (in Russian with awful translation so could not get much out of it) where the guy was saying that the TDA 7851 amplifier chip usually has too much power for factory speakers (he was not talking about Audi in particular). I spoke to Junsun and they told me they would look into it and try to find the solution but in the meanwhile, I asked for more specs. If I cannot find a solution I will return the hu.
I leave here some technical specs to see if anyone in this forum is able to help me. If I find a solution where I have to replace some speakers or get an amplifier I don't mind. I was thinking if it is possible to get a non-amplified output from the head unit and connect it to an amplifier that distributes for the other speakers.
Audi A3 8P
5 speakers in front and 2 speakers in the back
year: 2010
Head Unit: Junsun V1 pro (I will not post a link because I'm not sure it is allowed)
8-core / 4GB / 64GB
Radio chip: ST7708
Amplifier chip from the head unit: TDA 7851
DSP / RDS: Yes
Android 10
outputs: 4*45w
I found the first picture online but the interior is the same. I also leave here the wiring diagram, according to Junsun I just have to connect the main bay and then 2 RCA's for the rear speakers and 2 RCA's for the auxiliary input.
Thanks a lot for your time

I have the exact same symptoms in my audi tt mk2. As i had no experience with the oem radio i just assumed it was the car that had bad sound and bought an under seat subwoofer.

Thanks for leaving your input.
Did the subwoofer solve the problem? I want to test with another speakers to see how the sound comes out of the junsun head unit. Also I will try to take the car to a friend who is able to measure what is coming out of the unit channels. I will report back.

The subwoofer addes base, which made the sound good. But would not call it excellent, just good enough that it doesn't bother me.

Maybe try the DSP and play with the subwoofer low pass frequency adjustment, it may be filtering out the low frequency to send to a non-existing subwoofer.

Atoto ATOTO A6 PF A6G2A7PF

Hello everyone,
This is my first post in the forum and it is also important for me to say that I am not a radio or Android expert by any means, I will try to be as clear as possible, and I will try very hard to understand your answers. If you can be more detailed it might be helpful.
I want to buy a Android head unit and after looking at several brands I think I want to go with ATOTO A6 PF A6G2A7PF, made the decision based on price, seller in USA, advertised features and reviews I found on line. I would really apritiate any help with the following items I have not been able to find for this or any other Android Head Unit:
1) Is there a better unit for around the same price?​​2) is there a website or something where I can buy the radio harness for my specific car?​​3) Do I need to buy something to be able to us the Bose factory amp's, the atoto comes with some line to converters not sure if that would work?​​4) How can I retain Steering wheel controls? I have been told for my car it is too hard as they are "standard resistive button signal" and other said "it was by impedance"​​5) can I add a usb hub or splitter to connect two things to one USB port on the unit?​​6) I have read a lot about CanBus integration how do I know if my car can do this?​​I will install this in a 2001 Nissan Pathfinder LE that still has the stock Bose premium Audio system and I want to keep the amp's and speakers as is for now. suv Las has a second row screen and a VCR in the cargo space that is connected to the Bose unit. any Ideas was can be done with this or upgraded too.
Thank you
