Android Head Unit + Pioneer DEH-PRS80

Hello everybody , I'm owner of Ownice C200 Chinese head unit and i hate about audio quality and Bluetooth. I was using Behringer UCA 202 Usb dac but few months ago it stopped to work. Dac working with other devices but with head unit it is not working. When i use USB audio player, I can hear sound via headphone but from stock car speaker , no sound. For this i bought line converter to connect directly RCA from USB dac, but then i learned it need amplifier to power speakers. ( if i am wrong , please correct me)
I search a lot of topics in XDA and i saw one message using two head unit in car but there is no more information. I want absolutely same things. I want to use Pioneer deh-prs80 ( i will hide it somewhere in car) and will continue to use Android head unit for navigation, watching movies, rear view camera purpose. Is it really possibly ? I don't want to install any amplifier to my car, i don't need loud music, i just need clear and crystal music. I have hertz esk 165.5l as speaker.
If it's possible how will be connection ? Car battery enough to make power for both head unit ? ( i will connect speaker wire to directly pioneer) , is it possible to connect android head unit to pioneer via aux or Bluetooth or what ? I wish when i use android head unit, sound will go to pioneer and this head unit amplifier to speaker quality sound.
I also wonder if it is possible can be sound quality difference playing directly from pioneer or through android head unit to pioneer ?
I hope this topic will help to people who suffer from audio quality expect other features in android head unit..

Nobody can help ?

Well I would connect it via Y Splitter and the Front RCA out on the HU would go to the AUX in the Pioneer deck and connect your bluetooth to the Pioneer HU instead of the Android. You would have to zero out the sound from the Android and adjust your EQ settings from the Pioneer to get the best quality needed.

Head unit with fully working bluetooth?

Does anyone have an recommendations on an double din android based head unit that has a fully working bluetooth module? Something that can pair with and control an Alpine PXE-0850S amplifier. Does such a head unit exist?
Thanks

I would also like to know if such a product exist.
With new headunits including plenty of memory, storage, fast a75 cores and 4g -but high noise floor and only 2 slow usb ports+crippled BT is such as letdown :-(

I noticed the Atoto units have two bluetooth modules and support bluetooth tethering. Any chance those will pair with generic devices?

Well, I answered my own question by buying an Atoto S8 and trying it out. The second bluetooth module seems to be a normal fully working module and does pair with the Alpine amp and allows the amp settings to be configured using the Alpine app. However, since the amp also supports bluetooth streaming, whenever the head unit connects to the amp over bluetooth it routes audio output from music apps (but not the radio) via the bluetooth connection (instead of spdif), bypassing the head unit volume controls. So whenever I want to change the amp configuration I have to pair it with the head unit, run the Alpine app, make the changes, and then unpair the amp. Grrrr.....

Newbie: Android tab hooked up to Sony BT Amplifier w/o head unit

Hi Everyone,
I hate stock car audio set ups and can't stand how bad the stick head units are in my country India.
I'm planning on buying a new car, the Nissan Magnite (the base version usually comes with just the Aircon and no bahut, music player or speakers) and wanted to set up the ICE without any stock components. Could you help me understand if the following set up would work as I'm describing it.
Car amplifier: Sony XM - GS6 (with built in DSP)
Head unit: Samsung s6 tab lite with wireless charging dock
Speakers and sub woofer: haven't finalized, evaluating options
1) can I install the amplifier in the 2 din console space, have the tab connect to the amplifier via Bluetooth and the tab becomes the default screen. Is this possible?
2) since the tab will be playing the music, can it also act as a DSP or an equaliser via any available apps? Like what's the best way to get quality output from this setup?
3) can the controls be set up to connect the following to the tab, either via Bluetooth or via USB or via 3.2 jack and finally control them either by voice assistant or dashboard control buttons on the tab:
a) steering mounted controls for music player and calling,
b) FM radio antenna to connect to the tab,
c) reverse mirror, obd scanner, Aircon controls?
Thanks in advance!

Bump!! Pls reply to a noob
TIA

Android head unit bass missing

Hi all
I bought an Android head unit for my car to replace the original system. The unit is working fine (apple carplay, which is the main use), unit bootd and all is ok except the bass frequencies are hardly audible.
My car has an OEM amplifier which turns on with the unit and volume is good so I know the radio sends out enough volume to drive the amp. I do not have direct speaker connections in the car.
The car is an Audi TT roadster from 2007 with the standard audi oem amp.
I have read about MCU patches to fix the bass issue, but I am having trouble identifying my unit to find a patch. Below are some pictures of the system informarion of the unit.
If anybody knows a solution, I would be very gratefull.

Bluetooth audio not starting automatically

Hello, I've got a Chinese headunit and recently setup headunit reloaded app on it for wireless connection. The wireless connects well but no audio comes out through car speakers automatically. If I navigate to the phone app on the headunit and select Bluetooth audio that's when the sound starts playing.
Would anyone have any suggestions how to make the Bluetooth audio start coming out of car speakers automatically?
Previously I was using Zlink for wired android auto and audio would start automatically.
