Yep. I know from my earlier posts it might sound like I'm trying to piss on their parade. That isn't what I'm trying to do at all. However, I am very black and white on this kind of ****. I don't believe in 'feels'. "It's got a DSP so it must sound better" is not evidence whatsoever. All of the units, barring a very small number, now have a built-in DSP into the chipset. This provides the granular EQ settings that are found on the Xtrons units for example and so far, matched with the TDA7851 amp chip, has been getting nothing but positive remarks. I am also able to comment on the quality of audio provided by the Xtrons unit I fitted. I'd say it beats the OEM stereo, which wasn't cheap and the levels of EQ modification allows me to far surpass it with some fairly trivial tweaks.

If they're going to do this properly, they need to compare like with like. If they compare with the MTCB units or Joying units then it's like comparing Apples with sausages. My mobile phone probably produces better audio output than those early MTCB units and the Joying's aren't that much better.

Like I said, feels mean nothing to me. I don't give a **** whether they put a sticker on that says 'DSP'. I want it to sound better. Simple.

Looking at that screenshot of the DSP app, a lot of the features look like what a Viper4 would have... I might just take the plunge and flash Magisk on mine to see how it handles Viper4
[MTCD Android Head Units General] skezza:
With the exception that obviously all of the effects are handled and processed by that DSP chip, so offsets the work from your CPU. V4A is software driven, so inevitably adds a small amount of extra work on the CPU, n a head unit though, that might be ideal because you're unlikely to be gaming or doing anything that fully hammers the CPU anyway.

I can see there are some potential benefits to a dedicated DSP, but what I want is proof that there are 'real world' benefits. If the benefits are 'feeling good' then I'd rather go and spend £70 getting drunk on a night out. So far, all I've seen are 'feels' and nothing that actually demonstrates a marked improvement.

Here is a picture of the new moded board it look similar but if you look close you can see the red resistors is no lo get there
[MTCD Android Head Units General] blue_racer:
Sorry, I do not really see red resistors.. so do not understand.

May you show what is inside the isolation of the external rca cable?

[MTCD Android Head Units General] blue_racer:
Thanks, found it at 14:41 in the video: https://youtu.be/HGD2Aii_vx0?t=881

But I also do not have them inside.

May you open isolation of the external rca wire to show what is inside, please?

Hi I am trying to show you the mainboards or not the same as you can clearly see difference in the to boards on the dsp board and surroundings

hi sorry cant do that the radio is all ready install in my van
[MTCD Android Head Units General] Blueone:
I completely hadded with Androidautoshop, the support is the worst I ever seen. a tip, never order at this place.
[MTCD Android Head Units General] wboops:
Hi guys thanks for giving me that push to buy another unit. I have purchased my new unit from Alibaba.com the unit is working great and I have is order a new IPS screen the Dsp is really working great no problem to complain about thanks guys
[MTCD Android Head Units General] skezza:
You quoted me.....
[MTCD Android Head Units General] jtrosky:
I was considering one of these units from AndroidAutoShop. A few things made me back off:

1. This thread. Lots of bad things about AndroidAutoShip have been mentioned in this thread.

2. The Chevy-specific version of this radio appears to be a cheap Hizpo-like radio. I bought a non-DSP Hizpo unit that *looks* exactly the same and was not happy with the overall quality of the unit (loose knobs, poor heat-sink design, limited video-out functionality, bluetoth quality, etc). Not sure if the internals are the same as the Hizpo, but I have a feeling it's basically a Hizpo with the DSP chip added. I ended up with an Eonon GA9180A and it's better than the comparable Hizpo unit in just about every aspect.

3. Poor return policy (have to return within a week).

4. The fact that it has a TN display. I really wish these units had an IPS display!

While I like the flexiiltiy the added DSP chip offers (gives you more tools to allow you to customize the sound to your preferences), I'm hoping that Viper4Android will give me enough flexibility to make me happy. Plus, I plan to use an external amp that has auto-tuning capabilities built in (Kicker KEY180.4 amp - look it up - it sounds great).

It seems most of these Android head-units have crappy TN displays. I wish they sold "high end" versions with higher quality audio internals (high quality DACs, 4V pre-outs, better screens, etc). I'd be perfectly willing to pay more $$$ for them if they offered one. Unfortunately, you can't find a real Android head-unit from the "big boys" (Pioneer, Alpine, JVC, Kenwood, etc).
[MTCD Android Head Units General] AndroidAutoShop:
Hi, and thanks for the feedback, Our units have IPS and are made by the same manufacturer as Xtrons. Eonon GA9180A is made by Klyde and has a TN panel.

All the PX5 units we have are IPS panels.
[MTCD Android Head Units General] jtrosky:
As I said, I was referring to the Chevy-specifc DSP unit (XV8, I think) and when I asked your company if it had an IPS or TN screen via email, I was told that "the DSP units have TFT". I still have the email.

Are you now telling me that the Chevy-specific DSP unit has an IPS screen?

If not - are you saying that you do have a Chevy-specific DSP unit that *does* have an IPS screen?

This is the kind of "bad" stuff that people are talking about in this thread. Your reply was very misleading. I was talking about one unit (the Chevy-specific DSP unit) and you're talking about a non-DSP, non-Chevy specific unit (unless I'm misunderstanding something). My understanding based on the reply I got form your company is that none of the DSP units have IPS screens - and this entrie thread is about the DSP units you are selling.

So far, every Chevy-specific Android head unit that I've seen has a TN screen - the Hizpo that I purchased (same as Xtron unit) advertises an IPS screen but it's the exact same screen as the Eonon GA9180A that I bought (I have both side by side right now and they behave *exactly* the same in terms of viewing angles and the "reverse video" effect at certain angles.

Comparing the Hizpo Chevy unit (whcih I believe is exactly the same as the Xtrons - the user manual even says Xtrons on it) and the Eonon GA9180A, the Eonon is better is every way, from faceplate quality (knobs, etc) to performance to functionality. For example, the default music player on the Hizpo unit would "skip" as it was scanning the SD card for cover art, etc. The Eonon didn't skip at all during that same process (same SD card!). The Hizpo could only send video output from DVD or Aux-in (Eonon send it from ALL sources). The Eonon has two SD slots - one dedicated to GPS and one dedicated to media. Like I said, I couldn't find one thing that the Hizpo/Xtrons could do better.

What I'd really like is a Chevy-specific unit with DSP *and* IPS - and I couldn't find such a beast...
[MTCD Android Head Units General] skezza:
A week return? That can't be true surely? How can you be sure something is going to run well for a long time with just a weeks work. Most defects do manifest themselves at the start, but a week is pushing it!!
[MTCD Android Head Units General] jtrosky:
That is a correct - a one week return period.

Here are the questions I asked AndroidAutoShop and their answers:

I'm very interested in the XV8 DSP unit that you sell, but I have a few questions:

1.* Does this unit have an IPS or TFT screen?

2.* Can you change the button backlight colors?

3.* Can you send video output to headrest monitors (from DVD/SD/USB etc) while using navigation on headunit?

4.* What is the warranty lenght?

5.* What is your return policy if I'm not happy with the quality of the unit?

Thank you very much!​

And here is how they replied:

Hi, the DSP units have TFT.*

Yeah you can change the colors of the buttons

You can send video to headrest yes.

Warranty is 1 year.

you can always return the unit within 1 week after receving it.

Kind Regards

The Androidautoshop team

www.androidautoshop.com​

My *guess* is that they order these from someone else and that seller has a 30-day return period. So if you buy from AndroidAutoShop and want to return it, you have to return it to AndroidAutoShop where they check to make sure everything is included, etc and then they return it to the people that they bought it from. The one week return period ensures that they have enough time to get it, inspect it and then return it to the original seller withing 30 days. But that is pure speculation on my part - I could be wrong about that. Just a theory...

In the end, I'm glad I went with the Eonon - so far, I REALLY like the unit - but I am still in the "bench testing" phase and haven't actually installed it "in car" yet. While I can get a good idea of sound quality "on the bench", I need to get it installed in-car to truly evaluate things like sound quality, screen usability, steering-wheel and warning chime functionality, etc.

What I'm trying to do right now is get copies of the firmware and MCU files in case something goes wrong and I need to revert to stock - but Eonon isn't cooperating - they seem reluctant to send me the files. So I need to fight with them a little (if anyone has any hints, please let me know!). I just don't want to have an issue and need to wait 3 or 4 days to get the unit back up and running. Perfect example, I emailed them last Friday and they didn't get back to me until the morning (some Chinese holiday or something). I can't just go 4 days without a car radio if something happens...
[MTCD Android Head Units General] bombername:
to be honest, i dont think there are ISP Headunits out there.

It seems every display has the same manufacturers and in the videos i dont see any differences.

If you want to know it for shure, you have to order some units to test it.

But if i see, that new PX6 cpu have the same resolution (1024x600) i dont trust any china brand. :laugh:

I trust my eyes only.
[MTCD Android Head Units General] jtrosky:
There definitely are DSP head-units out there. Read through this thread and you will see actual pictures of the insides of the units - some have an extra DSP chip added - and if that DSP chip is installed, you can also see the extra options in the stock "Amplifier" app. The DSP units definitely exist. However, I'm not so sure the DSP chips are really all that good - you're much better off with an external DSP processor anyway. :) But, they do exist and you do have some options...
[MTCD Android Head Units General] bombername:
My friend, i´m talking about the kind of display -> ISP.

Not about the DSP. ;)
[MTCD Android Head Units General] blue_racer:
I've been in contact with AAS for a while regarding the sub problem on DSP radio.

After a long back and forth (yes, the support is not the fastest!) I will now get a replacement motherboard with DSP to fix the problem.

I am curious and keep you up to date.
[MTCD Android Head Units General] jtrosky:
Ah, I see. I saw "ISP" and just assumed it was supposed to say DSP being that the thead is about DSP units. Part of the reason I never even considered that you were talking about screens is that it's not "ISP" - it's "IPS" (In-Plan Switching, I think it stands for). :)

To be completely honest, I find it ridiculous that they are still using TN displays in a car radio in this day and age...

I *so* wish that there were high-quality Android head-units available - whether it be from Chinese manufacturers or elsewhere. At least have "low-end" and "high-end" options... I'd *gladly* pay more for a unit with an IPS screen and high-qualiy internals (DACs, DSP, 4V pre-outs, etc). But right now, it seems that you are pretty much stuck with low-end audio if you want an Android-based head-unit.

But, on a positive note, from what I've read, the audio quality of the units *is* getting better - it's just a slow process...
[MTCD Android Head Units General] bombername:
You´ve got it my friend!

But so far, i guess we have to play with that what we can get right now.
[MTCD Android Head Units General] Flemischguy:
Almost 2 weeks ago, i installed the radio in to my car. I have to say that the sound is amazingly good, rich deep and crisp high, what a difference with my previous old android radio who only had 3 settings, high, mid and bass, much better fm reception, smoother reaction on the steeringwheel knobs and good phone calls on both sides on the line.

I connected my gps receiver thats in my shark fin antenna and receive all 12 GPS satellites, even in my garage.

So i'm quite pleased about this head unit

It's kown that the PX5 gets pretty warm, i see that the cpu reaches 65°C if some apps run in the background, i feld it geeting warm up when i was testing it before i mounted the unit in to the daschboard, i know i will void the warranty, but i gonna mount a fan in the radio to cool down the cpu.

Meanwhile i see there is a new CPU on the market, the PX6 which is a hexacore with 2 A72 cores and 4 A53 cores.

BTW... Will it possible to upgrade to a RK3399 soc instead the whole motherboard or in worst case, the radio it self?

If so, i hope they will provide a fan to cool down this CPU, it wil provide a even faster system like they show in this video on 8:35 https://www.youtube.com/watch?v=LL1t1jdyT5k
[MTCD Android Head Units General] jtrosky:
Exactly which unit did you purchase? Also - does your sub-out work? I've read about the sub-out not working right on these DSP units. Curious if that has been fixed.
[MTCD Android Head Units General] Flemischguy:
To under stand my set up i will tell you this story.

I have a BMW E46 2003 coupé face lift model, and when i bought the car there was only a single din radio bussines cd in the dasch which i later replaced by a single din alpine iva d105 with screen of 7 inch screen with gps.

Couple years later i wanted more punch sound in the car, so the guys of that same car audio shop who placed the Alpine radio, din't have much or no space behind the radio when they installed it because of the single din bracket.

They installed Audison speakers and high tones speakers in the front door and audison speakers in the rear and the Audison AV 5.1k amplifier who can handle 'rca in' and direct input from the audio out that normal going to the speakers but now goin first in to the amplifier, also they modificated the audio out wires on the iso connector.

So my setup is quit different than the most user here. My subwoofer has a remote control for the volume and i can adjust the bass level thrue the equaliser of the radio.

I let them installed my first android radio and they modified those wires (i wasn't aware of that) so for me it was a surprise when i installed this new radio from Android Autoshop and i had to cut the 2 delivered iso connectors and solder them together with the right pins for the audio to the amplifier.

Sorry for the long long reaction, i hope i explained it right.
[MTCD Android Head Units General] AndroidAutoShop:
The sound is amazing yes.

SUB port has been fixed in newest revisions of units with DSP. We are still working with hal9k to get a few optimizations in. new updates will be released Over the air.

PX6 will be coming in a few months time. but expect to have stable software for this in 3 months.
[MTCD Android Head Units General] Flemischguy:
SUB port has been fixed in newest revisions of units with DSP you say, What about the first units that doesn't have a sub out because a fault on the board?

Could they be replaced?

Is it possible to swap the soc on the motherboard with this new cpu?

Regards F.G.

AAS DSP Radio *new generation*

Last week I got a new mainboard from AAS for my BMW E39 DSP radio.

It's amazing, now I got clear sound and sub out also.

They've created a new mainboad, another DSP platine and if I'm right a stronger AMP TDA7851L.

New will also be, that radios will come with a HAL9K-based firmware. :o

Added a new site at our wiki.

Negative points:

- support is still slow

- still no manual for DSP menue (but in process)

I noticed that they removed the "DSP" from the radio descriptions. Do they no longer sell the DSP-modified versions? They still show the DSP "Amplifier" screenshot in the pictures, but there is no mention of DSP anywhere else (they used to specify DSP right in the title, etc)...
[MTCD Android Head Units General] Blueone:
I still didn't get my money back while I send the unit 6 weeks ago. This company cannot be trusted, if you receive a unit you are lucky but better not to buy anything here!

I could care less about the amplifier in them as I use an amplifier for my sub and a very good 4ch for my mids & highs, I have the xtrons 10.1 with the px5, it's rooted running the maylay rom butter smooth, I believe it has the dps built in, I use the neutron music app from play store and all of the nice crossover features work along with all the parametric eq to widen bands and all, I may eventually hook another pair of small tweets to the head unit itself, mine was ran through the bose system amplifier at first, so I never really heard what it sounded like with just the units built-in amp..

I like the look of the app I seen in pictures above, how can I get that apk on my current unit..?

Thanks
[MTCD Android Head Units General] govno64:
Just wanted to add for anyone looking or searching google: I just installed a ISUDAR Android 8.0 4gb Ram head unit with octacore Coretex A53 1.5GHZ processor with added DSP and the DSP is awesome. It's much better than my stock head unit and has some really great control options - I'd definitely say the quality is comparable my old Alpine head unit, and I would be very impressed it it weren't making this kind of clear output without an upgraded dedicated DSP chip.

FWIW I installed this android head unit in my 2007 Volkswagen Passat 2.0T with factory Dynaudio Amplifier system and it makes the factory stereo (which was already awesome - seriously Dynaudio makes some kickass stuff) sound even better. It worked out of the box with the factory amp, no special CANBUS, Wire Splicing or VAGCOM programming needed.

It's a little laggier than I had expected (especially considering its 8-core with 4gb ram), but even still for $250, I'm pretty damn happy with it. Now I just need to find a way to get it to start booting when I unlock my car, instead of when I put in the key, cuz the startup time is a good 30-45 seconds.
[MTCD Android Head Units General] colins:
The main audio issue I've noticed is a constant low level white noise whenever the unit is unmuted.

Did you install something additional, like a DAB+ receiver?
[MTCD Android Head Units General] fjer:
I'm very confused by all this DSP talk. :confused:

I'm using an external amplifier and would like the best possible audio quality on the RCA outputs, so I was looking at an XV8 (androidautoshop.com/volkswagen/128-1147-volkswagen-9-touch-screen-dsp-android-80-4gb-32gb-entertainment-system.html - sorry, I'm not allowed to post real links yet).

I don't use the built-in amplifier and I don't need/want equalization, so I asked AndroidAutoShop whether that device would be a good fit for me. They told me that they recommended the FX8 (androidautoshop.com/volkswagen/231-1747-volkswagen-9-touch-screen-android-80-4gb-32gb-entertainment-system.html) because it is a superior device, and the DSP is not relevant to me when I'm using an external amplifier.

I was under the impression that these DSP boards were more like sound cards rather than just signal processors, seeing that they seem to have such a large impact on the sound quality, and according to some of the tech specs posted here they have their own DAC and ADC chips and everything.

But if the DSP output is only connected to the amplified speaker outputs, it must be a different story...? Would the RCA outputs even work in a unit with DSP?
[MTCD Android Head Units General] bisy:
Hi,I also have same question for DSP output and please experts for help,In my car is factory sound system with factory amplifier,I like to know if DSP gives signal on RCA AMP. OUT connectors or signal is same like on NON DSP UNITS ????
