A quality DAC will certainly improve sound. But low voltage outputs will not create distortion on their own is all I meant by my post. I cant even count how many times I have helped friends "fix" their ****ty sounding system by properly adjusting their gains. We can go on for days about all the things that affect sound quality though.
[MTCD Android Head Units General] hv006:
Hi guys,

im trying to make a choice between the dasaita or xtrons for vw, i dont have a external amp and for me is sound quality really important !

if i read the comments good the dasaita units have a better internal amplifier is this right ? im compare this 2 units :

https://nl.aliexpress.com/item/Dasaita-7-Android-6-0-Car-DVD-Player-for-VW-Golf-Polo-Passat-Tiguan-EOS-with/32801805772.html

vs

https://www.aliexpress.com/item/XTR...ler-Radio-voor-vw-Volkswagen/32850136721.html

so for sound quality i can better go for the dasaita right ?
[MTCD Android Head Units General] bavarianblessed:
It's supports DAB+ with the optional adapter
[MTCD Android Head Units General] bogdi1988:
DAB+ is useless in the US anyway, isn't it? :)
[MTCD Android Head Units General] bavarianblessed:
Which can be rectified with a qulity pre-amp. I picked up an Audio Control Four.1i just for this reason. That and this unit doesn't have a volume knob which is a must for me

Except the P5X units all use the same craptastic DWC-OTG USB 2.0 controller from Designware/Synopsys. There are alot of issues with DAC quality and compatibility on this USB controller stemming from excessive interrupts. I don't have any first hand experience with it yet but there are some very well versed guys on it, THIS post specifically from [MENTION=6011328]aluver[/MENTION]

Yeah pretty much lol
[MTCD Android Head Units General] esounds:
The problem with audio quality is that all these vendors rely on the chipset (extra focus on the word "set" because there is a DAC within the AllWinner and Rockchip chipSETs.) Add to that the outputs on RCAs being between 0.5V and 3V.

The chipset Xtrons uses is the more advanced of those out there but you have the challenge of relying on a Chinese chipset as opposed to what Alpine, Kenwood, etc. use such as Burr-Brown (now TI), Sony (makes their own), Wolfson (now Cirrus Logic,) etc.

The advances in CarPlay and AndroidAuto are moving so fast that you might as well look at something like Kenwood's wireless CP/AA to work with excellent audio quality. I love the apps and cool functions out of these units but these are car stereos first, app tools second. The Chinese don't get that yet.
[MTCD Android Head Units General] naplesbill:
If ultimate sound quality is your goal, I agree with you. But having had AA in my 2017 F150 from day one, it still doesn't do what a full Android HU can do. So, I do the best I can with an aftermarket amp and speakers and enjoy the extra functionality of a full Android HU.
[MTCD Android Head Units General] CadillacMike:
i know this is getting derailed into a car audio convo, but I have been trying to figure this out and glad I stumbled upon this...

so would my best option for sound be Dasaita > DSP > Amp?

and if so, what would i plug into the DSP, the speaker wires or the RCAs?
[MTCD Android Head Units General] bavarianblessed:
If you are running analog to the DSP then you would use the RCA outputs. Never use the speaker outputs for signal unless you have no other choice.
[MTCD Android Head Units General] CadillacMike:
OK, next question

Say is get a DSP and get it all tuned and whatnot. Does that mean I don't use the EQ in the head unit anymore?

Like I put the EQ to flat as I tune I assume. After the DSP is tuned, does the head unit just stay on flat? Or would you still cycle through the presets like Rock, Jazz, etc
[MTCD Android Head Units General] bavarianblessed:
Ideally you want as pure and dynamic of a signal as possible through the pre-outs. So you would keep the EQ off if possible, the less processing in the source signal the better.

If you are tuning the system via the external DSP then leave all tone and frequency adjustments to it. Of course once it's all said and done if you want a little more mid bass and the DSP can't add it then try tuning it in on the headunit EQ. Just don't over do it.

The best signal would be from a USB DAC out of the headunit into your DSP. Pretty much every external USB DAC available is going to produce better sound than the pre-outs will provide.

I'm looking to get this one
[MTCD Android Head Units General] CadillacMike:
I remember back when I had a Joying people were trying to get USB DACs to work.

Currently I have a Dasaita Hot Audio unit that has Android Oreo and 4GB of RAM, it runs like a champ, which is why I am more interested in bumping up my system.

So if the USB DAC works with the Dasaita, you would hook that up to one of the USB ports, then a 3.5mm comes out of it?

So i would need a DSP that accepts a 3.5mm Aux type cord?
[MTCD Android Head Units General] lowridincrew,:
Every head unit has a distortion ceiling. Some distort at 34/35 Volume, some are perfect and some are just trash. It's determined by the output of the RCA signal. 4v would be sufficient for a aftermarket system. My Kenwood has perfect levels at max volume. Toss in a Android unit or other, distortion starts right before I get to the max.
[MTCD Android Head Units General] naplesbill:
yes, that is what the gains are for. if the volume is too low when setting the gains to avoid distortion, you can use a line booster to improve your gain adjustments.
[MTCD Android Head Units General] CadillacMike:
i was looking into this, and I actually already own one of these:

https://www.crutchfield.com/p_703DGNFLYR/AudioQuest-DragonFly-Red-v1-0.html

i have it plugged into my computer. I might try it out on my Dasaita and see how it works
[MTCD Android Head Units General] bavarianblessed:
Nice, I'd be very curious to know how it worked.

I was looking through the hardware specs and found that the board uses a Wolfson WM8978 audio codec.

https://www.cirrus.com/products/wm8978/

Looking at the pinout it seems possible to connect RCA outputs directly to the chip which would bypass the internal opamps and MCU all together. I'm going to pull my unit out and start digging around
[MTCD Android Head Units General] bogdi1988:
That's cool! Subscribed to see where this goes. How would you do the 4 channel and then the sub output with it? This is only 2 channel, right?
[MTCD Android Head Units General] bavarianblessed:
Correct it would be for stereo output only. You would need a separate pre-amp and amplifier to use it this way. I have an audio control four.1i so this is perfect for my needs. We'll see how feasible it is
[MTCD Android Head Units General] bogdi1988:
The output from the stereo goes into my OEM car amp. Sub has its separate pre-amp and amp.
[MTCD Android Head Units General] bavarianblessed:
So it turns out that the SOM has a WM8758B not a WM8978.

It's surface mount but the legs are exposed, as small as they are. Not sure I'll be able to solder to that

[IMG="TE706PL codec"]http://ts.evilsmurfs.com/audio/Xtrons_codec.jpg[/IMG]

Here is the data sheet for it - looks like the DAC is slightly better in this chip compared to the 8978
[MTCD Android Head Units General] robertugrenovic:
Hallo.. do someone know where must illumination come??

My car harness have not the same (ILL) wire like my autoradio..

I found it..

Another problem now, I bought new speakers Focal ISC165 Integration 2-Wege Coax 16.5 cm https://www.amazon.de/dp/B00C3Z46YQ/ref=cm_sw_r_cp_apa_pORIAb7TTKDDC

but Bass sounds less good than by the other old factory speakers

https://www.ebay.co.uk/p/Hyundai-I30-Rear-Left-Door-Speaker-96330-2r000-2010/1115917329

is that because new one are two way speakers or what??

bass was exstra by this old ****y one, but now isn't so good?

please help and thanks

So i've decided on the Xtrons TE697P, seems like the same unit plus a dvd drive. Px5, 4gb ram, 32 gb rom, android 8.0. should be a nice upgrade to my current unit which is the atc ac8227 unbranded android 5.1.1. I'll post some pic and reviews of it once i got it. Pretty stoked though. Here's the one i'm ordering..

https://www.amazon.com/gp/product/B079QJ29TS/ref=ox_sc_act_title_1?smid=A1MITD5Z5MU6OM&psc=1
[MTCD Android Head Units General] soudy1994:
I was about to buy this but then i noticed the low screen resolution.

Most of other head units have more resolution than this.
[MTCD Android Head Units General] Slatz81:
6,95 all have 800pixels Maximum, not only xtrons. it´s the Screen/Display manufactorer

the 7inch Screens are way, waaaay better.

DVD is dead, buy the 706PL instead.
[MTCD Android Head Units General] woomdawg:
I just ordered the 7" unit, I have wanted an Android head unit for a long time. So excited. I plan on using a 120gb external SSD. A co-worker told me that an SSD on an Android head unit would be slow. Does anyone have any input? I don't think it is true. I also want to stick a 128gb class10 sd card. Can I have the SSD and card in use at the same time? Like 2 separate drives. Does anyone know if they can be rooted and pure AOSP flashed?
[MTCD Android Head Units General] snaggle2thtiger:
I've had my TE697P installed a couple of days now. I am very happy with this unit. The different menu takes a little getting used to but the boot speed is close to a factory stereo. Have only had it cold boot a couple of times but even after working 5 hours and coming out for break it will pull up Pandora with in a few seconds and start playing. I have had car web guru crash a couple of times but I feel like this is possibly due to the app not being optimized for android 8.0. The silver bezzle around the unit is actually metal and gives a nice look especially since my interior is already black and silver. The lower resolution is a little more noticeable than i expected but i needed the dvd because i have an 11 month old and we take road trips so dvd playing to head rest monitors will be necessary for me soon. The amp outs really don't sound bad at all. I didn't have to push the gain too hard and this time around all of the apps seem to have similar sound quality and output. My last android unit had a big issue between apps making it nearly impossible to use some because of the huge difference in output to my sub. In spotify and Pandora you couldn't even hear the subs while in the normal radio and YouTube my side mirrors were shaking. This seems fixed and I am super happy with it. If you've been dealing with slow boots and are running external amps I definitely recommend this unit.
[MTCD Android Head Units General] atlpimpneega:
I have this unit too and am happy with it. I can't get DirectvNow to work on it because it doesn't recongize the headunit. Any suggestions?
[MTCD Android Head Units General] bogdi1988:
How's the audio quality? Anyone go from like a Joying to this? Curious how it compares to that...
[MTCD Android Head Units General] therick3:
Looking at getting this head unit as well. Does the dialer app support receiving and making calls from two or more phones? I am sure 2 or more phones can be bluetooth paired but i would assume the app would need to support it?
[MTCD Android Head Units General] jtaylor8328:
Thoughts on another Xtrons 10.1"

I was really considering the Xtrons TR100. I'm installing in a 2001 f-150 which doesn't quite have full double din opening and this model wouldn't require as much fabrication. This one however only has 2Gb ram and the T8 chipset. I don't need the DVD player. Do you have any thoughts or recommendations on the TR100?

Not allowed to link yet but they sell them on Amazon. Only 2 reviews but both fairly detailed and 5-star
[MTCD Android Head Units General] naplesbill:
Well, unless you need the ability to rotate the screen, the TE103P has twice the RAM. The installation needs would be the same for either. IMO, the extra RAM is the best feature.
[MTCD Android Head Units General] jtaylor8328:
Decisions Decisions

I keep bouncing between the two Xtron 10.1" units and an Atoto A6Y2721PB. Love to hear your feedback on the TE103AP when you get a chance to really run it through the paces. I've heard better things in regards to Atoto customer service than the Xtron but I can't speak to that first hand. The Atoto also comes with the external mic and will be $100 cheaper. Also, I've read some places that Xtrons has 1 yr warranty if you buy direct or 1 yr if you buy somewhere else. The TE103AP is $75 cheaper on ebay vs their direct site. So hard finding reviews on these Xtrons so any feedback you have would be huge in my decision making.

Thanks,

Justin
[MTCD Android Head Units General] bogdi1988:
Check Amazon also. Last time I checked it was a lot cheaper there
[MTCD Android Head Units General] jtaylor8328:
The TE103AP is unavailable on Amazon, has one sub par review. It's $399 on Xtrons and $329 on ebay I think. Amazon the TR100 for $285 with two good reviews. The Atoto is prime for $239
[MTCD Android Head Units General] bogdi1988:
Weird! Must have sold out. They still have the 7" model
[MTCD Android Head Units General] jtaylor8328:
I know but I'm really diggin the idea of a 10.1" screen. The 7" model does seem solid though.
[MTCD Android Head Units General] JaPeMo:
Hi friends

I am very interested in this unit but I am worried about the comments and problems about the Bluetooth, ECO and noises in the calls that have been commented on the units of the Xtrons seller.

Can someone tell me if this has been fixed with TE706PL units?

Thanks & Regards
[MTCD Android Head Units General] atlpimpneega:
Just returned my TE697P....my audio suddenly went out on it and after taking it to Best Buy and a local audio shop no one could figure out why. I can confirm that call quality was horrible. Maybe I got a bad unit but I did love the quick boot up times and the fact that I had waze nav and could watch movies without it being mirrored or tethered to the phone. I ended up buying a lower end Kenwood with HDMI input that I plug my firestick into for movies. Welp, it only lasted about one week! I wouldn't buy this unit unless you have a local shop that sells it to where you can easily get a refund or exchange without having to ship it back to Hong Kong.
[MTCD Android Head Units General] JaPeMo:
OMG!!!!!

I waiting a new unit to send to Spain from UK. At the moment are paid but they dont have stock in Aliexpress... I'm very confused about what unit buy... :(

I don't know what to do... cancel or continue and test unit...

I see this:
[MTCD Android Head Units General] bonfire62:
I think only one person said the bluetooth call quality was bad so far. It also may just have a really bad internal mic. I ordered a separate mic to install near the dash. I'll let you know how it goes in a month once it gets in :P
[MTCD Android Head Units General] atarum0r0:
Xtrons TE706PL have sd slot? ty:D

I've got the te706pl installed for Couple of weeks now and pretty pleased with it.

One thing that bothers me though is that the pins for can bus are empty on the main radio connector so I went to their forums to ask around but I am still waiting for an admin to get it approved. So maybe someone here has already tried to connect the radio to can?
[MTCD Android Head Units General] JaPeMo:
What Amp chip have this unit?
[MTCD Android Head Units General] marchnz:
Does it matter when all the TDA variants used in MTCD are all so close in RMS power output? Would think if i mattered, additional power amps be used.
[MTCD Android Head Units General] yellaboyla:
Figure I would add my 2 cents since I have owned 2 different Android head units. I had the Eonon 10.1 tablet and the Joying 7in 1GB ram.

I had to return the Eonon 10.1 after about 6 months in my F150. The wiring harness just isn't cut out for movement. My screen started losing certain primary colors, so I would have to wiggle the unit around to get the color back. I never detached it. this started on its own. So FYI

The Joying units do suck with power output to RCA and speakers. As a couple of you guys mentioned, 4V pre-outs are the norm in car audio. I believe most of these units get lucky if they reach 2V, and that is not consistent. I got around my pre-out issue by just adding a pre-amp. I used a Pyle 4V, pre-out EQ. Same as adding an Audio Control device. I just boosted the radio with the EQ, then sent the signal to my amps. Same as a line amplifier.
[MTCD Android Head Units General] bogdi1988:
Got a link for that Pyle 4V? :)
[MTCD Android Head Units General] atarum0r0:
I just ordered the xtrons te706pl I hope I will have no problems
[MTCD Android Head Units General] yellaboyla:
basically the same......higher pre-out voltage

I've owned two Xtrons head units and will never buy another as long as I live.

Their customer service is awful. You'll wait weeks to get added to their forum, and if you have issues or complaints, they won't post them in the forum. Consider your purchase to not include any customer support.

My first unit was an older (4.4) Android that was ahead of the pack Android version-wise when I bought it. Only, it had issues with BT, and did not support WiFi, because the dongle they said worked with the head unit did not. The buttons beeped this horrible tone with no way to turn them off.

I went to a Joying Wince system for a couple years, and then gave Xtrons another chance. I had the unit for a couple months, and had issues with BT pairing, background noise, and a screen so glossy I couldn't see anything on it with sunglasses on. In those couple months, Xtrons never responded to emails or added me to their forum.

So good luck with them. In my experience, they're out for a quick buck in the US market. I have a Joying Intel unit currently and am quite happy with it.
[MTCD Android Head Units General] tabocaw:
Does anyone else have battery drain issues with this unit. My truck wouldn't start multiple times so I replaced the batteries and started checking the voltage before I started the engine. With the new batteries my truck still is dropping to 11.4 volts overnight. I've already checked the wiring and also I set it to shut down completely after 30 sec. Still no help. Any ideas?
[MTCD Android Head Units General] halegdoi:
i have not this problem. xtrons turn of when car is off

Just ordered one. Can I use a third party rear camera and dash Cam dvr or does it have to be xtrons. If a third parties please can you guys recommend some.
[MTCD Android Head Units General] derjuden:
So wanted to post my experience with this head unit. First off I've never had an Android headunit so I can't compare it to any of those.

1. Sounds quality is good. Seems to be about the same as an average stock car stereo or $1-200 aftermarket stereo.

2. Bluetooth never worked on my unit. No phone could see it, and it could not see any phones or headsets. Updated firmware from the manufacturer and still wouldn't work.

3. wifi stopped working after about a week. It would connect but would not get outside the local network. factory resetting the unit fixed that but with the bluetooth still not working I'm going to send it back.

4. Buy it on amazon, if they don't contact you back within 1-2 days they get a plenty or removed from amazon market place so they have to get back to you. Also buying it from amazon with free shipping was overnight from HK to the US for me. I'm near LA so it showed up 1 day after ordering it which was pretty crazy.

5. Overall I like the UI, performance, and features. I will say there user manual is a joke and really doesn't tell you anything. Also the wiring diagram card they give you is also a joke but all the wires are labeled individually and on the unit itself. So wiring it up is not hard if you have ever installed a radio yourself.

6. The main harness did not have wires for the CAN-bus. the pins are on the head unit itself but the harness doesn't have them at all. I am hoping to get a proper one when i get my replacement unit.
[MTCD Android Head Units General] imarian1984:
Hi guys,

I'm new to this forum, so volume of information is for now overwhelming for me, and also new to Android HU. I'm planing to buy Xtrons TE706PL from their shop on Aliexpress to update the old old HU (branded NAvd-8923 with WinCE) that I have on my Kia Cerato 2006 (Spectra known by others).

Have been filtering results and compared specs/prices for few days now and just before I could make my final decision/place order came across this forum and found that are some users of this model.

So can you guys please tell me if this choice is ok, from the specs sheet and price seems to be, but I'm also interested in other users experiences with it. It will be mostly used as a media player (audio&video from sd/usb) and navigation using waze (also want to order their 4g dongle).

Thanks for you feedback!

XTRONS Installed

I just installed my deck into a 2009 Routan. I still have to cut into my opening to remove a metal brace, but it is deep enough to hold it in place temporarily.

As stated in a previous post, the screen only swivels up and down. The issue I find is that sometimes some apps require a portrait view and so some apps are not viewable.

Second, even though it has play store, contacts and voice do not sync. I don't know the issue. I did download google contacts sync, but it just hung on syncing contacts.

I love the deck and I am working to wire a backup camera. It is speedy, screen is generous especially for my old eyes. I love that it is android and not a muted version, .ie Android Auto.

I forget the app, but it turns on hotspot when the bluetooth contects to the deck. Works awesome. Videos work while driving without any fancy wiring. Waze will detect speed by GPS, but they are good enough to allow you to enter information as a passenger.

Wiring for me was a breeze although I am a meticulous fella. I bought the cheap metra harness only to find out later about canbus etc. Fortunately or not, my van is a very basic model with no steering wheel controls or amp. As such, i bought a iso harness and this allows me to click from deck to iso to metra then car without splicing anything. I hooked up the red power to the spade connection behind the keyed usb port.

Downside is I cant figure out the orange wire which should go to illumination. I tried going from car harness to deck, orange to orange, and no deal.

Second, I really miss a volume knob. Nuff said.

Lastly, the phone app sux. Initially, I didnt even know how to dial out. There is no phone app or dial app. It is a function under the bluetooth app.

As I mentioned, contacts and google voice do not sync, so there is a problem there too.

I tried rooting through KingRoot. No go.

Overall, it sounds good, but mines is a stock audio system. I am still pleased, but I didnt think through these smaller things, like no interface to phone, voice dialing, etc. etc.

Hopefully someone will create an app.
[MTCD Android Head Units General] bogdi1988:
For orange you can pull a wire from the headlight switch. Pretty much any 12V feed from there.
