how to use the AUX port on the Android head unit?

Anybody knows how to use the AUX port to play music through the head unit?

Hi, I have the same doubt here. I bought a pure Android unit (still trying to find out which make and model is, as it's unbranded, with RK3188A chip, but not matching any MCU listed on the HuiFei wiki page), and I see that I can only use the dual zone for DVD while navigating (IGO) on the head unit. I mean, I have no PIP functionality (not a big issue), but the dual is not working as expected. I can only send video to rear monitors if it's played from the DVD. No USB, SD, BT, etc music or video files seem to be allowed to be sent through the AUX out port. And I'm only allowed to use navigation app while DVD is played on rear monitors... No radio, no USB, SD, etc video or audio files.
My previous unit is a WinCE supporting really well all this functions, but unfortunately due to a battery power loss, it only starts in recovery mode (expecting to load some firmware from SD card), and I cannot find any FW valid for it. And this pure Android is unable to do it, so I'm investigating to come up with a solution (it's the main reason I bought the pure Android unit).
Anyone knows any option? I think this could be done via software, but maybe I'm wrong.
Thanks in advance, it's really appreciated.

you'll need a 3.5mm/2.5mm male to 2 RCA cable,connect this cable to your MP3 or someting and the AUX IN L and AUX IN R cables ,open the AV IN app on the head unit,then you can listen to the music through your head unit

So, you cannot play music from a friend's phone and use tomtom (or any app) in the meantime?
There is any possibility to have AUX-IN audio and any navigation app in the meantime?
Thank you,

You just bought the wrong device.
Nearly all units with DVD support only video/audio from this drive, nothing else.
All units without integrated DVD can play anything from anywhere, even from any USB-DVD.
From my understanding this cannot be changed...
May be possible by deactivating the DVD by pulling out the connection to the main board.... I don´t know, needs to be tested.

Where do you read that out of his posting? You always can send the AUX player to the background and can use navigation.
By the way... for what reason did you activate the donate button? Did you create any helpful software to ask for donation?

MY unit has AUX in but no AUX in app. Does anyone have the APK or one they recommend? MCTB running android 10.

How do I delete this I accidentally posted in wrong thread.

Ah, someone said it was. What is it?

I don't know if this applies to all firmware, but on some firmware, you either see the AUX or the Front Camera app icon. In the settings, when the front camera is activated, the AUX program icon changes to a front camera. If you deactivate the front camera then the AUX icon appears and I believe the sound source input is also made active in addition to the camera. On mine, the option is under Factory Settings and is named "Front View" on can be toggled on or off.
I have a TEyes SPro 4/64 which is an s9853i FYT unit. You should check the connection diagram for your head unit to see which pins/connectors are for AUX video and audio.

Interesting so I can't use my dash cam and AUX?

Not sure. Try it and see what happens. Maybe your unit is different.
If both your dash cam and AUX use the same inputs, then I would guess that it's not possible.
Best to try and maybe follow-up with your vendor/seller/manufacturer.

I have a similar problem. I m trying to install an reverse camera. I have connected the orange "reversing" wire but when I am in reverse I get a "no signal error". What's the difference between video in and cam in connectors. Do you know what the pin out of this connector is because the rca female cables are not installed and I m trying all possible combinations in order to connect the video in and grnd cables from the male rca. Thanks

Android HU: Junsun DVD-9.0-AN Android 4.4.4 9.0 inch

I was considering this HU for my 2016 VW Polo since I don't care much about having a DVD slot. The title for this HU says DVD but it doesn't sport a drive. Though the spec seems good (RK3188) and the price isn't much either I didn't find any reviews or information about this HU on XDA (or outside).
There are couple of places this is being sold from Ali express to GearBest and also on their own website.
Does anyone have any thoughts on this one? Specifically I was looking for community support (root, custom firmware). Since this sports a RK3188 chip can other ROMs be used on this? Also the HU has a very thin form factor (compared to other HUs) - so would heat be an issue?

Who knows?
It doesn't have a volume control knob, if you can live with that. Personally, on screen adjustments for volume, track selection, "back," and on/off is very unhandy and annoying. You can't just reach up and adjust it with out looking. Also the volume steps of the touch controls are not always small enough to set a precise level. These units, with no US contacts or service, are a pain if you need something. Carjoying is in the US and quite responsive. Updates are also made.....who knows about those other relatively unknown products. They may never update and may no work with other software. I have never seen a 9" screen wonder if the thin bezel is just a half inch smaller and uncovering the edges of an 8" panel. This is just conjecture but perhaps worth considering.

Thanks for the response. I ended up placing an order for this unit instead. I dropped the other one mainly due to there being hardly any orders and reviews. I also did not get any proper responses from the sellers regarding that unit - probably since its new and they are themselves unaware of its features/fit. I agree about the support issues but I also had a tight budget and as long as it works fine :fingers-crossed: I should be OK. Importing these into India attracts a sizable customs duty The unit I bought costed me about $190 shipped via FedEx so I expect the customs would be proportionately lower.
Regarding the volume I have steering wheel controls which should serve the purpose of physical buttons. Though I agree that having a knob is more convenient I also kind of like the flush surface of these full touch units - lesser issues of dust settling.
I will post an update here once I get the unit and install it. BTW the reviews for this on AliExpress are excellent - would love to hear from anyone already owning this. I asked the seller about rooting and custom firmware (kind of essential for android units) but didn't hear anything positive This lack of support and the fact that this is an AllWinner solution (R16 QuadCore Cortex A7) were the only two drawbacks I saw in it (given its price).

How to root Junsun Android 4.4.4
I purchased this unit also from gearbest and like some things about it, but question other things.
The good:
1. The unit is ridiculously thin for a car stereo. There is no CD/DVD player
2. Sound is actually decent. Little difference from the stock unit
3. The home page with rotating icons is cool and different. I can also put a live wallpaper behind it
4. Mirroring app works ok, but I'd rather tether.
5. I can play videos and music on a USB flash drive
The bad:
1. I can't launch other apps and listen to music at the same time. (i.e. when I load Google Maps, radio stops)
2. No native capability to bluetooth tether. USB tethering with EasyTether also didn't work.
3. There are no microsd inputs like other Chinese Android units I've see thus far. I can connect a USB drive to 2 available connectors routed from the back of the unit. This isn't necessarily bad. Just requires different process for rooting that's TBD.
4. Instructions are only in chinese. Don't know who really makes this device, or how to get their technical support. So far, gearbest has provided some answers, but they're far from accurate!
So that said, I'd like to root and install some different apps and drivers that might make USB or bluetooth tethering possible. And that might allow me to listen to radio or USB music or Pandora while I have something else like Torque or Waze running.
Here are settings from the unit:
OS Version/Build Version: JAX1602191130G-WQ-16EN
MCU Version: 201512161416-SLX7786-GEN
CPU Model: RKPX3
Android: 4.4.4
There is also a 'system' page, where I can go to advanced, press 1234 as the password (found it through trial and error) . A screen is then available to upgrade MCU or firmware. However, I don't know where the files should be placed for this screen to register them.
Any pointers on process to root this and/or install something like Malaysk Firmware? Thanks!

This is really bad since it defeats the whole purpose of an Android-based HU. Are you using the stock music app or trying something you installed?

I think all these units restrict the bluetooth to the MCU and is generally not available to other apps. Though I am not sure how Torque works.

This is a problem with most Chinese purchases - informed support is almost non-existent. However since you have an RK3188 based unit I think some of the support threads here may match your unit (at least partially). First try to get into the extra setting menu using the passwords given in the RK3188 threads and rooting as well. You need to find the thread that matches best to your unit/firmware based on trying out the various settings/tweaks. Don't flash anything till you are certain you are in the correct support thread. All the best!

I am sure that this is some soft/firmware restriction. Android 4.4 has a native support of multitasking, so it should be by default in any of core versions of this OS. Main problem that I didn't find any resources where this issue was resolved.

Mine will !

This is really awful - how can they sell a "Android" HU with such limitation? You should give the seller an earful and a bad review for the unit so they are forced to fix it!

I have the same unit also , the camera doesn't show when I am in reverse mode , the steering wheel don't work with the radio, rkpx3 model

I need to know what MCU is installed on this unit . Someone has any clues ?

You can have a glance at this Pumpkin HU for VW, http://www.amazon.co.uk/Pumpkin-Android-Navigation-Subwoofer-Multimedia/dp/B01D30XDXY/

Lol. Even on the official video where this HU was demonstrated , MCU version is 'unknown' ))) http://screencast.com/t/RnQxbkAZBaWX

I bought this device.
The menu is exactly the same, firmware is the same: JAX1603281325G-WQ-16EN.
There's a microSD slot on the front panel.
MCU version: 201601251011-SLX7786-GEN .
Built-in player and radio can not work in the background, and this is the biggest trouble. There is not a full solution is to install third - party players who know how to work in the background, for example: BlackPlayer. But unfortunately, in third-party players do not switch tracks from the steering buttons. Adjust the volume and MUTE works as it should, because these buttons are programmed for the entire system. I liked that as a quick call navigation, you can assign any button on the steering wheel and choose any app.
The unit is decent, especially for the price. But such silly mistake with a built-in player and radio can wipe out all the pluses. Wrote to the seller, promised to talk to the engineer, perhaps

Typo?

Is that a typo? There is NO microSD slot on this unit. You can connect a USB Flash Drive to the USB connections on the back of the unit though.

No. I have already found it when disassembled this HU. Its located on left edge of device. You can use it to flash ROM , or like normal SD... Now I working with stock firmware, trying to solve all issue mentioned in this thread. Its not so easy... bcz this MCU and firmware are not usual for this type of HU, and I didn't worked with this OS before ).

I noticed that the built-in player and radio do not have the manifest permissions to change the audio system settings ("modify audio settings"). Using APKEditor added this line to manifest, but to save, unfortunately, did not work, because I get the error message: the program is already installed and is missing a digital signature. If necessary I can put the modified and the original source code of the apk "music" and "radio"... Now are struggling with receiving the digital signature, the idea is APK Editor must sign the modified apk with the native signature. Apparently, there is some protection.

n the process of using the device revealed the following shortcomings (about the first two already written):
1. Not running in the background built-in music player . That is, when playing music you can't use Navigator. You have to use one or the other.
2. Not running in the background built-in radio programme. That is, while playing the radio you can't use Navigator. You have to use one or the other.
3. Not running in the background audioclub built-in bluetooth . That is, when playing music from phone via bluetooth you can't use Navigator. So you have to use one or the other.
4. After the completion of the incoming call via the bluetooth Protocol SOMETIMES falls off the sound of the entire device. Most likely, the audio service bluetooth does not give audio device. You have to reboot the head unit by switching off the ignition.
5. I really want the joystick on the steering wheel could switch tracks on ALL the audio players and not just on the built.
6. Lost sound player and radio when you lock the screen (press on the power button), which is very inconvenient at night, since I want to eyes did not detract.
7. It is unclear how sync contacts via bluetooth. Some appear, some don't.

I received from the seller working firmware, music is now able to work together with NAV. If anyone needs - let me know.

Eonon GA8198 - Noobie Questions

Hi guys - I recently installed one of these into a Mazda 6. (px3/7.1.2/Arm Cortex Quad) My first toe dip into the Android Headunit space.
Couple of outstanding questions:
[1) I previously had a Sony Bluetooth module plugged into the aux in port. The A2DP on this unit sounds terrible by comparison. (CD Player sounds great) The Sony seems to support a HD codec. Are the codecs in the hardware/firmware for the BT module in these units? Specifically:
a) Is it possible to install more advanced codecs such as AptX HD via a software update/install?
b) Is it possible to connect a better quality BT USB dongle and use that with the on-board BT disabled?
2) I would really like to be able to use Android Auto. I have installed Head Unit Reloaded, and I can get this going with Wifi Direct, but if I plug my Pixel 2 XL into the USB ports, all it will do is charge. I have checked with Emil, and he seems to think this is not the expected behaviour. Eonon support say that is all that is supported. Dashcam etc works OK.
a) I assume ports on these types of head units are USB OTG? (Is that how it works?)
b) Maybe ScreenCast or something is taking the defaults for phone connect. I've been through every app on there I can find. Any other hints?
c) Has anyone had Headunit Reloaded working on an Aonon unit with the USB cable?
d) Is one of these Car Play/Android Auto USB dongles likely to work if I buy one?
3) What are people doing with multiple drivers of the same car? Setting multiple Android/Google profiles and switching between them somehow? Or making an generic Google account for your car?
4) I'm noticing some dashboard lights flashing briefly on the dash (Traction Control) etc when the ignition is on. Need to pull it apart and disconnect the stereo to see if it is causing this. Has anyone else experienced it? (Eonon sent me a firmware update to fix this, but it is just the same)
Any help appreciated! Or to just know if anyone else is using one of these.

Update for #2. I flashed the latest firmware Eonon gave me, and (that caused a few Wifi problems) but now if I disable the EzConnect software they supply Headunit Reloaded works

Can you tell me if you have any issues with yours?
1) I have electrical engine whine noises over the speakers.
2) Some crackle.
2) The top LED display beeps twice every few minutes and flashes "NAVI" up.
3) Running Headunit Reloaded works now, but it randomly disconnects every few minutes or so and I have to unplug/replug. I've read this could be a cable issue that is specific to the Pixel 2 XL.
It's possible I have a cable short or similar behind the unit, but wanted to check with someone else before pulling the dash all apart. Cheers.

Newer Joying head unit

Does anyone have this newer Joying 8.8" widescreen single DIN head unit with the new UI, JY-HOS01N4GS-2 ?
I just got it in and am trying to set it up before I install it in the car. Can it be modded or customized? While this new UI isn't that bad looking, it's a little more modern, but it does have this damn clock on the right side taking up real estate on the screen and I can't get rid of it. I tried using another launcher but the clock still stays there. I also can't get it to connect to my BT keyboard even though it sees it. Nor can I get it to see a universal USB cam which I want to use for a rear view mirror display. I did get it to recognize the universal non-Joying internal sensor TPMS unit I got as well as XTRON front DVR cam (I had to use the program on the XTRON cam to see it though) and an XTRON backup cam.
Can anyone help or point me in the right direction for modding this unit?

Anyone? I did find an app that can see the universal cams now but still need help with the other stuff. Plus I want to change the boot logo to an animated one I made.

I don't have such a unit, so I would not know about your Launcher, but it has been mentioned before in the forum. Please search a bit more.
You can only connect phones and approved devices to your device on BT. See this post and further for a possible modification.
Most universal usb webcams are not supported.

Why the hell do they do that? If I had known that before hand I would've probably went with another unit like an ATOTO or a Dasaita. I went with this one because the widescreen 8.8 IPS display fits my car perfectly plus it has a 4g module built in. (grumble)

Dasaita is microntek. All those units have crippled bluetooth as well. It is something the Chinese do to promote selling their own stuff, I guess.
No idea about Atoto though.
Does your keyboard have a usb-dongle? As far as I understood, keyboards with a usb-dongle do work. All BT equipment relying on the host bluetooth are hit-and-miss, and almost always miss.

No. It uses whatever's is built in to what you want to connect to I guess. I do have a Bluetooth CSR 4.0 dongle and tried using that on it but I can't see where it recognizes it.
The HU sees the keyboard it just won't connect to it. I damn well better not have any problems connecting to my OBDLink MX when I put it in the car. ?

Ok I tried what they said to do in that post but it didn't work. Not sure I did it right. It appears all I had to do was copy those two files in that bluetoothsetting.zip to a clean SD card put it on the HU and reboot it.
If that's what I was supposed to do then no luck. I have read that the firmware on these widescreen units are slightly different than the other Intel Airmont units.

No connection

Dear Sir .
Good day
I have a car head unit android TS10 . Android 10.
There is no connection for wifi ,Bluetooth and gps .
Please any help

Per description the headunit comes with "Bluetooth-Enabled, Built-in GPS, MP3 / MP4 Players, Radio Tuner, Touch Screen, TV, DVR, Backup camera". Look into its user manual to activate the features. Or ask seller / manufacturer for help.

It needs to be updated or reflash the original firmware.
I don't know why head units for cars are so popular, the technology isn't mature enough yet, they all have too many bugs and issues to be truly convenient or worth it in the long run, a waste of money in my opinion.
