Will cheap eBay USB dab adaptor work with Joying? - Android Head-Units

Hi guys,
I just bought a new Joying 2gb HU with buttons. I'm thinking of adding dab radio and on joying website the adaptor is $80 but I can get one on eBay for $5-$10.. That's a pretty big difference in price for basically the same thing.
Something like this http://www.ebay.com.au/itm/142202102357
Can anyone verify if these will work with the HU?

These cheap SDR adapters do not work with the DAB app that is preinstalled on Joying units.
Only Wavesink app works with these SDR Adapters.
I tested both variants and I sticked with the Joying adapter and the preinstalled app.
SDR = Software Defined Radio

So just to verify, yes they do work provided I download another app but this isn't the best option and if I want it to work best then I should go with the joying adaptor?

Yes, I did a comparison of
Wavesink app + SDR adapter
vs
Joying app + Joying DAB adapter
regarding usability and reception and audio quality.
Joying has won.

Dodgy reception

Hi,
I have a Joying head unit (about 3 years old) and Joying USB DAB adapter bought in June 2017.
The reception has always been a bit patchy where I live but perfect where I work.
I have now bought an active antenna from ebay.
This antenna now provides good reception where I live but where I work it drops in and out from 5 bars to nothing.
I have been following the signal quality and near work when it drops out, the value fluctuates wildly up to 1200 (480, 1000, 700, 1280, etc).
When its working as expected the signal quality value is 40-70.
Is it possible that there is now too much signal ??
I have been using the modified app from July 2018, would it make a difference to upgrade to the App store version?
Thanks

Is there an Audiophile grade Android unit yet?

I'm waiting for an Audiophile grade unit. Is there a unit out that has the following:
Hi-Res DAC (Hopefully at least 32-bit/192kHz)
Optical out
Volume Knob (not a deal breaker)
3gb of ram or more
speedy processor
Nice screen size at least 7"
Nice 31 band EQ or 15 bands for left and right
And if these are not available, are any of the manufacturers on this board that can push for this type of product? I truly believe if there was such a unit, that they would kill the market in one year.

First, there are no such units available.
Second, I think you overestimate the market for something like that. The "audiophile" is a very VERY fringe market.
What is needed, is generally better quality hardware. Something with mainstream parts, like a high end qualcomm SoC, and supported by some outfit that is actually *COMPETENT*.
The better overall quality hardware would naturally have better quality audio come along for the ride, and this would definitely be enough.

What would be the 'best' constructed head unit right now?
I was looking for an Android head unit, and my car dealer wanted to sell me a Parrot Asteroid Smart (with an amazing Android 2.3 and 512MB memory...).
I did multiple searches and got to no conclusion. Probably the best quality 'chinese' head units right now are joying and Xtrons, but even they are not specially good at audio quality.
I read there was a posibility to 'hardware-hack' some PX3 units (but I wanted PX5...)
Any recommendations?
I have recently just removed my android head unit from my car and reinstalled the standard head unit.
The audio out of the android unit is horiffic to say the least. The standard headunit knocks the socks off of the
android unit plus they have the cheek to advertize it as HIFI quality sound.

Dynavin units are the closest from what I've heard with Burr-Brown DACs. But the actual Android side of things is a bit dated

The hardware hack on the PX3's you are referring to... is that the one where they disconnect the BD37xxx from the MCU and connect it to the SoC? If so, point your sights at an INTEL JOYING, because the BD37033 *IS* connected to the SoC, and is directly controllable.

What head unit?

I know this has been asked a million times but I keep seeing "this brand is good" and other threads supporting "that brand sucks".
I have $150-250 USD for a head unit and am looking for recommendations.
Needs:
non-factory Reverse Cam
Front DVR capability
GPS
Steering wheel
4g capability
Would prefer 4gb ram but if budget limits I would go for 2gb as long as its solid and can Nav w/ music without issues
(going in a 2014 subaru wrx)
TIA

Sound Quality on PX6 units with DSPs

I recently purchased a Mercedes 2005 CDI and I gotta say I love this car. The COMAND is solid but definitely outdated. I started looking around for drop-in head units and found the 2 big players Avin and Dynavin for the W211. No looking at older posts (2018 and before) i hear a lot of people beating up on the units because they are Chinese made. But present-day it seems like there have been strides and upgrades in chips that are being used. So I'm wondering is there really going to be a noticeable sound difference between a Bluetooth-connected 3.5 mm adapter going through the command and a properly tuned Avin or Dynavin unit going through a MOST adapter to a factory amp and speakers? Looking at XDA it seems like the chips used in the AVIN is TDA7851F (I am waiting on confirmation on this from AVIN). The TDA7851 is actually the same as a pioneer chip (https://forum.xda-developers.com/t/a...2171s.3891089/). The Dynavin is a burr-brown (or Texas Instrument chipset) now I'm not sure how plays with the most adapter. But in the end, it seems like the hardware is there for improved sounds. Does anyone on here have objective data to swing the conversation one way or another?
The other question is longevity, I've heard the Dynavin units generally have generally received pretty decent reviews and have pretty decent support. I have not heard anything from long-term owners of the Avin. If there are any on here have your units functioned long term?

Best audio quality

Which of the current 7" double din PX6 hexacore headunits offers the best sound quality? I love the convenience of the other apps but at the end of the day music is what I play most. Built in 3G or 4G modem would be a plus. My current Joying has one and it works great. No need for wifi or dongle.

Best amplifier chip / DSP or not

Hi,
I'm just looking for a new Android head unit for my car, and here's what I found on Aliexpress :
First one is a Seicane branded one, with AC7315 amplifier chip according to the seller, and DSP built-in
Aliexpress Link (Select "WIFI(2G 32G)H5N-RPH" )
Second one is a GiantLion branded one, TDA 7388 amp chip according to the seller but without DSP
Aliexpress Link (Select "WIFI (2GB 32GB) D")
Which one would you think has the best sound quality ? Both do have an Allwinner T3 CPU so it's identical on this point, but I read somewhere about someone having a really poor sound quality with the AC7315 amp, so I found this unit with a TDA7388 but it doesn"t have DSP, so I'm a little lost...
Thank you !
Hi and welcome new member,
Not MTCD or hardware development, requesting mod moves. Allwinner T3 CPU are not MTCD.
In reply, both would be poor, suggest avoiding these units altogether.
Take a little time to read through the forums and familiarise yourself with the forums and unit types.
Thanks for your reply !
I'm sorry I didn't really know where to post this...
I have a good 4 channel car amplifier from Blaupunkt, do you think if I hook it up to any of these units the sound would be better than its integrated amp ? Like can the RCA output also be of poor quality ?
