New Joying PX5-based Android 8.0 Units - [Rockchip PX5 A53 | Android 8.0 | 4GB RAM]

I installed two different models of Joyings newest PX5-based head units. Both are the 7 inch screen 4GB RAM / 32GB flash double DIN model with flat buttons on the left edge.
Please note that as of May 2018, there appear to be multiple new 4GB / 32GB Joying head units have different internal hardware and are not compatible with each other or with the PX5 2GB Joying head units.
JY-UM128N4PX5 is a QD unit
JY-UO128P4 appears to be an FYT unit
Buyer beware. My recommendation is AVOID the QD based units and seek out the FYT units.
See below for more details.
The following information is for JY-UM128N4PX5. Further down the page is information for JY-UO128P4.
=============== JY-UM128N4PX5 =================
Came with Android 8.0.0 installed.
APP Version TP6735 0.0.65
MCU Version TP6735 4.40
Kernel Version 4.4.103
Master password:126
Password for changing logo:0000
Password for changing UI:8086
So far I have noticed the following:
The unit does not trigger the amplifier turn on signal wire - the orange and black wire labeled AMP-CONT always measures zero volts on my voltmeter. Workaround is to use either the antenna signal wire, or the ACC power signal wire, to turn on your amp. Joying is aware of this issue.
Sleep does not work. The unit shuts down completely about one minute after you turn off the vehicle's ignition. It doesn't sleep and then come back on instantly like my Intel-based Joying unit. Boot time is about 20 seconds. Joying support now says that sleep is not supported on the QD units.
I cannot find the radio settings in the new radio app. You used to be able to slide the bar at the bottom of the radio app to get to settings. Now in Android 8, there are a couple of radio settings that have been moved to the main android setup dialog.
Some of the functionality of the former car settings app has been moved to the android settings dialog. But not everything is there - for example this is where I was looking for the ability to tell the unit to toggle the amplifier signal wire. I could not find any such setting.
AM radio reception is non-existent - static on all AM channels.
FM reception is good, but I cannot figure out how to get the FM Radio to enable display of song and station information - this used to be under RDS settings, which no longer exist.
Bluetooth calling works fine. Seems more stable than my older Intel-based unit.
Sound quality is good - I am using an external amplifier.
The logo set up is missing Porsche and Saab Logos. My Intel-based Joying unit had these. Easy enough to load my own custom logo.
The unit ships with Joying's "Launcher3" selected. On the home screen, the labels of the bottom row of icons are cut off. The screenshots on Joying's website show the same thing. The joying2 launcher is missing.
If you reflash the unit, the vertical keypad on the left side of the unit gets un-mapped and stops working. Fix is to go into car settings and remap it.
========================= JY-UO128P4 ==================
Android Version 8.0.0
Build Number px5-userdebug 8.0.0 OPR5.170623.007
System Info APP 1024x600 2018-04-27 21:42:36
MCU Version 2018-01-23 10:59:33 JY_(R68)_R-86C-096I-NC-NP-1.0-P12S
Passwords:
Factory settings: 3368
Developer Options: 3368
Reset: 3368
Password for changing Launcher:8086
Password for changing screen current:
So far I have noticed the following:
The software on the JY-UO128P4 is very close to that of my older Joying Intel based system.
The developer has replaced all of the system settings screens native to android with their own settings screens. Not super cool. All of the car settings and android system setting are now intermingled.
Upon unboxing, the JY-UO128P4 has only a single Wifi antenna wheras the JY-UM128N4PX5 had two (diversity) wifi antennas. I have not tried to compare reception differences.
The amplifier turn on signal now works as expected (AMP-CONT wire correctly signals 12V when unit is active)
Sleep works as expected
AM radio reception works weakly.
The FM radio application works as expected. Radio app settings are accessed within the radio app. It's possible to enable RDS for song and station ID within the radio app.
All of the joying launchers are available - I prefer launcher 02 and it's available on this unit.
Many more car logos are available on the system. Porsche logo was built-in.
The only things I've noticed so far that are worse with the JY-UO128P4 than the JY-UM128N4PX5
The unit suffers from the android 8.0 bug on Joying where all of your google contacts are deleted if you allow your account on the head unit to sync contacts with google.
As noted above - the native android settings panels are all removed.
The app for setting the color of the buttons on the side panel is limited to pre-determined solid colors - yellow, white, red green etc. On the JY-UM128N4PX5 you could select and set any RGB color, which made it possible to match the button illumination to your other dashboard lights.
As I learn more, I will post more.

I cannot find most of the passwords needed to set up the unit. The master password is 126 - I found that by watching a joying video. But I cannot find the second level passwords for changing the logo, changing the launcher, etc. Anyone have the other passwords?
The utility to change the color of the buttons on the left side of the unit works, but the buttons do not illuminate one the unit is booted.

I cannot figure out how to change the launcher - with the default launcher the lower row of app icons is only half visible on the screen.
Who else has a new Joying Android 8 unit - what else are you seeing? Has anyone found solutions to the items above?

I have had several back and forth emails with Joying support in the last couple of days.
They are trying to find the passwords for their new units under Android 8. Support didn't know. They had me try 00000 and 123456, neither of which worked. I told them the main password is 126 - they didn't know this either. I still need passwords for all of the second level settings - change the launcher, change the logo, see if there are more developer options for car config, etc.
They are apparently aware that the AMP-CONT lead to turn on the external amplifier does not work. They recommend connecting the accessory wire from your vehicle to the amp signaling wire instead, so the amp will turn on when you turn your key to the accessory or on position, bypassing the head unit.
They acknowledge there are no detailed settings available for the radio under Android 8 in the radio app. So there is no way to turn on station or channel ID for US customers.
I also let them know about another radio issue - FM Radio reception is normal, but AM reception is awful to non-existent.
Google maps is ok, directions from Google maps are mixing with other audio ok.
Feels like Android 8 on the new Joying 4GB units isn't quite ready for prime time yet... Has anyone tried to upgrade a 2GB Android 6 unit to Android 8 now that the Android 8 files are on Joying's website? Do you see the same behaviors, or am I seeing hardware issue with the brand new 4GB units? I suspect it's all software, but would be nice to know.

The 2GB units are not compatible with the 4GB units. They need different hardware drivers and different MCU firmware as the firmware in the 2GB units is from FYT. I forgot the manufacturer of the 4 GB units but @gtxaspec knows.
There is no downloadable firmware yet for the 2GB units.

hi, i've the same unit and the password was noted into the user manual, it's 3368.

If you buy Joying android 8.0 unit the SKU like:JY-UO135N4PX5 or JY-UOS03N4PX5,password as below:
Master password:126
Password for changing logo:0000
Password for changing UI:8086

TomTom
It seams to be so hard. Again an Android HU, where TomTom navigation does not work. It let's me download the maps, but after that it crashes every time I try to load the application.

I can confirm these passwords are correct:
Master password:126
Password for changing logo:0000
Password for changing UI:8086
Other findings so far:
The illuminated buttons do work - they sometimes take a few seconds to come on after your illumination wire signals with 12V.
The logo selection with this new unit does not include Porsche or Saab. You can still upload your own custom logos.
I updated the unit to the latest (2018-4-20) release on the Joying website which is supposed to include optimizations and Zlink and my unit is now hanging at the Android text logo (right after the animated Android logo). I sent a note to Joying support for help and will also wait for a few hours to see if it comes back to life.

The same happened to me
After writing about 25 emails with Joying support I had to reflash the whole system ... loosing all my data.
For now I am really not going to try any more updates from Joying with this unit.
Really hoping for a Custom Rom & Root for this unit.

I have one of these as well. Any one find where the setting is to make the sleep mode last longer(2hrs) before it full shuts down? it seems to be locked on 30sec currently. Also it wont pair with my OBDlinkMX BT dongle. in the older MTCD units, making the BT password 1234 let you do it, but not here. anyone have any luck with BT OBD dongle pairing?

I was really leaning towards getting this unit but have been holding off because I wish it had Bluetooth 5.0, maybe I should wait a little longer since it seems to have a fair amount of bugs. I know a lot of people are happy with the Xtron since it has all the best features I just really prefer to have the buttons on the left like this unit has. Looking forward to seeing if you guys can get this squared away

I was able to get my unit working again by reflashing. It took about 10 tries with three different USB cards but it finally worked. Joying support provided a file that included a system image and a Window-based chinese language USB card writing programs, along with a word document with instructions. You build the USB drive and then plug it into the left hand USB connector, and click the reset button on the front of the unit. It loads, then tells you to remove the USB drive, and then if you are very lucky it will reboot into Android.
After re-flashing, the vertical keyboard on the left side of the unit did not work. Turned out the mappings had been erased. Fix is to remap the keys - there is an option in car settings.
Current issues still present in the unit seem to be:
Unit shuts off entirely after 30-60 seconds instead of sleeping when you turn off the vehicle. My intel-based unit sleeps for several days.
No AM radio reception - static on all channels.
No way to turn on song or station identification in the radio settings for FM.
AMP-cont signal wire does not work. I've worked around by wiring my accessory wire directly to my amp's signaling wire.
Have not tried Torque and Bluetooth ODBII reader pairing yet - on my list for this weekend.

So, it's not just me...
I purchased a JY-UM135N2PX5 (PX5 2G/16G) with Android 6.0 mid to late March.
I had it on my bench through April, testing and configuring it prior to install.
After trading emails with Joying tech support, I was sent an Android 8.0 update to address a Zlink/iPhone issue.
I started my install in the car today, and discovered "no sound". I guessed that the AMP-CONT wasn't turning on the OEM amplifier. I rechecked the cables, which checked out just fine. Tried a Joying JY-UM135N2 (Intel Sofia 2G/32G Android 6) on the same harness, and it functioned as expected (turned the OEM amplifier on and had sound). I took them both back to my bench and noticed that the "AMP-CONT" on the PX5 unit did not appear to have 12V on it, while the Sofia unit did.
I did not leave the non-functional PX5 unit in the car long enough to see any other issues.
I am curious if I were to revert back to Android 6 on the PX5 unit, if it would fix the AMP-CONT issue (at the cost of breaking the Zlink/iPhone functionality)

Would you be so kind as to share those files with us? This would be a good starting point for further testing and research. Simply upload to a hoster like mega.

Here is the reply I got from Joying support this morning in regards to the open defects I am tracking with the unit. I suspect that all of this will get fixed in subsequent software releases, it's relatively obvious stuff. Can anyone confirm if these same issues exist in the Android 8 builds on Joying's 2GB PX5 head units, or are these unique to the newest 4GB units?
Dear friend,
Please noted :
1) sorry that your system is different with Intel head unit , it do not have fast boot feature . so it will completely off .
2) for the AM receptions is bad , you need to set the proper time and zone . also the radio area choice .
3) sorry, the head unit you purchased do not have the RDS setting .
4) for the am-cont not voltage , please connect the ACC (red wire ) to your amplifier wire . then can offer 12V .
Hope your noted .

Are they serious? I would suggest to try the Malaysk Rom, i guess your units are MTCD and MTCE devices so maybe this rom would support the missing software like rds and the other hardware not supported by Joying

I have a 2GB Android version 8.0.0 unit, but my unit is a FYT based unit like the Sofia 3GRs, unlike yours which is a QD unit.
Mine does have fast-boot as my unit is a FYT based unit, using the same hardware/SOM as the Sogia 3GR intel units.
I never used AM-reception. I wouldn't know, but I know from previous users on Sofia 3GR that they also complained about the AM reception
Which RDS-setting? This is so confusing and so not concrete. RDS is a complete set of functions. The syu/FYT based software on the FYT based units support RDS-PS, RDS-PTY and RDS-TA/TP. The latest firmware versions on FYT units (Sofia 3GR and my PX5) also support RDS-RT. They do not support RDS-AF. They implemented "something" like AF. If you use that option it does not select the Alternate Frequency of your radio station, it selects the strongest signal it can find of any station. Note that it is the software. The radio chips in all these units support the complete RDS set of functions.
Don't know about the the amp-cont wire.
You ask about and mention AM and about RDS. I hope you know that RDS can only be used on the FM signal. RDS is not available for AM.

You have an Allwinner T3 chipset in your unit.
Do not use a Joying thread to ask a completely off-topic question.

I've received the same unit, facing the same issues as the OP.
Also the localisation in my language is quite poor.

I've bought this unit in the hope that it would be compatible with custom ROMs.
Are you saying that the unit MCU is almost unknown and that no custom ROM would be available in the near future?

FM Radio keeps scanning for stations

Hi,
I have one of the cheap Chinese Android 9.0 headsets with the PX6 Octa-core Processor 1.5 GHz RK3399 (Radio Chip NXP 6686). The model is Fongent Car Android 9.0 Radio Multimedia Player PX6 4G RAM 64G ROM.
The problem I have with it is that the radio will not stay on any station that I choose. Everytime, I switch to a programmed station, it starts to scans after like 10 second and always stops on the first station in memory that it had found. It is getting very annoying now. I tried to fiddle around with the AF TA PTY settings but that didn't do anything.
Anyone has experience with this radio app? Is there another one I can use that doesn't need internet connection to use and can use the antenna?
Please help!
Thank you.

Somewhere in the radio settings you must also select the correct region: japan/europe/etc.
Did you do that?

Yep, i had to do this on mines when i first got it. it was still set to China. Also if you flash the wrong MCU file it could also cause this issue.

I didn't flash anything. The unit is as it came from the factory. I did change the region to US. The radio has automatically programmed different stations under P1, P2, P3, etc all the way to P18 I think. But always stops at 88.7 New station. Even if I choose a different station like P5 or whatever...I get to listen to that station for like 5 seconds or whatever and then it starts to scan and then stop at 88.7! So frustrating. To the point, I just want to use a different FM app for this. But I don't know of any that uses the FM radio to broadcast instead of looking for an internet connection. I am not looking for internet radio.

It happened to me with some radio stations, I solved the problem by turning off the TA.

First question did you contact your seller about this? When you do get to listen to a station does it sound clean? Are you moving or parked? Can you manually tune in or enter a station frequency and see if it starts to scan again? It's possible your car has an amplified antenna and it needs a power injector. Otherwise I'd say something is wrong with the radio and you should send it back.

No I did not contact the seller in China about this. Yes the station sounds clean and clear. I have tried it while parked and/or moving. It doesn't make a difference. Yes I can manually move the tuner to a different station and it plays for a few second and then again starts to scan. It does NOT stay in a particular station other than 88.7. Everything was ok with the stock stereo that came with the car. Is there only on radio app on Android 9.0? Can I not try a different radio app to see if that work? Mailing the unit back would be more hassle that it is worth. To me it is a software issue or some settings/tweaks that needs to be made.

Well I understand that shipping back to China is less than ideal, but your seller is better placed to help you than any of us especially with the little bit of information you provided. Best case they can give you an MCU update that could fix the problem or at the very least work with you to adjust settings in the service menu. Or they may realize the MCU is defective and send you a replacement. The only alternative radio apps I know of are only for MTC MCU. Yes the radio chip is controlled by the MCU so you're not likely to find a generic radio app.

Take a look here : http://4pda.ru/forum/index.php?showtopic=973677
I use Google translate, but I am not brave enough to flash any of the ROMs from there.
I have the same unit I'm my Camry.

I have the same one, bricked it flashing boot.img patched by magisk. Supposedly magisk patched boot.img has to be flashed into 'recovery partition', not 'boot' partition. I have made more or less full backup of the unit but do not know how to enter recovery mode using buttons or shorting wires.
Regards

I have a Hizpo Android10 head unit with the same MCU version (I think, first letters are same: S32F0). Also interested in if there are updates available and how the h**l you can acivate recovery mode with button presses.

Hoping as time passes more will get these HU's and eventually root and cook a ROM for them.
Mine has a number of issues,
1) The OEM reverse camera only works for 3 seconds when selecting reverse then it switches off
2) The basic DSP works but the more advanced DSP doesn't
3) GPS is very inaccurate
4) No RDS
5) Volume and radio channels change by themselves
6) Car settings don't work
7) Open doors indicator is switched around, left door open shows right door on HU.

Are you sure you have the same unit?
Because:
1) My reverse camera works,
2) DSP Works
3) Gps never give me problem, error of 3 meters is normal
4) RDS works perfectly
5)Never happen to me
6) car setting works, i changed SW and other settings

Are you sure you have the same unit?
Because:
1) My reverse camera works,
2) DSP Works
3) Gps never give me problem, error of 3 meters is normal
4) RDS works perfectly
5)Never happen to me
6) car setting works, i changed SW and other settings
7) I didnt have that functions (in my car) so i cannot test

I have a RK3368 RockChip PX5 head unit with MCU S32F0 processor, I have no idea what one you have or if it's the same.
What I listed are the problems with mine, why I don't know, but as there's not much other recourse hopefully a ROM update might fix things with mine.

Thanks, I had seen that but the first post says (translated):
"There is essentially no information about it, there are no modified firmware either., The firmware in the header was sent by the seller and was not checked for operability, it is up to you to sew or not.
There were no known attempts to get root on the device."
so it doesn't seem much has been done

I see, but differents users who had gps/clock/rds problems solved it flashing the only mcu called rdsfix file. You can give it a try....

Here is the rom sent by seller yesterday, link available for 4 days.
Android 10 PX
HIZPO PX5C_C01_HA6_11211237
The gps works well.
No GPS navigator in the rom.
Torque OBD included
WeTransfer

Installation:
Copy the zip file to a USB stick or SD card formatted in FAT32
Put in the radio on, press RESET
The installation is done at restart, duration 10mns, remove the key or the SD when installation finished and green screen displayed.

I have an really odd problem with my HU, the reverse camera view goes off as soon as one starts moving and comes back on when stopped again. I fixed most of the other issues I had but this one still persists.
It's an Android 9 HU in a Ford Ranger PXII/T6.
Any ideas?

I had the same issue it turn out the video cable going from the headunit to the camera was bad

I have a Hizpo Android "10" Headunit (Advertising claims Android 10, but the unit actually runs Android 9). This model is specifically designed for BMW E90 Series cars, but I'm sure the chipset and software is the same across their devices. (Part: AD8CHKSOI2I08772)
Specs are the Cortex A53 Octa-core and 4GB Samsung DDR3.
Here is the Build number information from inside Android settings:
ANDROID: 213328
MCU: S32F0_XinRC-18_20199820_HA1_6686_D_FF_C8
APP: PX5_C54_HA1_XRC_EN2019-09-02-2008
The password for the factory settings on my unit is "0000".
Inside here there are a couple useful features such as:
1. Mute Radio on system startup
2. Reverse Doors for Car Overlay Feature
3. Change Boot Splash Screen
I am hoping to root this device so I can hide the Android navigation bar and convert over to gesture controls only, enable USB data tethering with my iPhone, and disable some system services/apps as the device can be laggy at times, unacceptable behavior with 8 cores and 4GB RAM, especially in mid 2020!
But overall I am happy with the device.

Bought my new head unit for Jeep Grand Cherokee from Erisin.
It is the new model ES8176J, PX5 Octa Core with 4GB RAM and 64GB ROM.
I was supposing that it was a MTCx but it seems that the MCU is the S32F0 one.
Do you know where I can find updates, modded ROM, root, etc?

I have a Zltoopai unit for a BMW e82. Think pretty much the same as jahjah440.
ANDROID: 145358
MCU: S32F0_XinRC-18_20200527_HD1_7708_D_FF_DSP_C8
APP: PX5_C54_HA1_Xrc2_EN2020-06-05-1728
I'm running it with a Carlinkit carplay dongle which works great. It just doesn't allow me to run radio in the background. I'd like to be able to set the carlinkit app as navigation app so it won't mute the radio. I can't do that now.
Want to get rid of the stock launcher because the unit keeps asking me to chose between that and Agama...
If it can do that it's perfect. Now it's pretty good.

8227L_demo

Hi,
hello, i bought this radio from aliexpress (https://www.aliexpress.com/item/4000620695689.html?spm=a2g0s.9042311.0.0.421e4c4dx9cnJf / MT8227L 4-Core Android 10 2GB+32GB (Radio IC: ST7708, Amp IC: AC 7315, DSP normal)) but the concerns turned out:
1) First, the radio always turns on for a long time (as if the memory is cleared. While the radio channels are still there).
2) Searching for a gps signal takes a very long time.
3) The radio loses the signal in the meantime when the car is switched off.
4) There are very few options to configure. Even in menu 8888.
There is no help from the Chinese. As always Tried different cables, locations, etc.
Since I already had one experience with Chinese android software, it is clear that the error is in android software.
Although there was another android radio but with malaysk mod software all the troubles were solved.
Here is the Chinese android radio software: https://drive.google.com/file/d/1z0UrWRHSb_ZCvt3YsDVytRMMHUutrVpT/view?usp=sharing
Can anyone help or provide better software or improve existing one?

From the few pictures you posted, I think your device is a FF-5500 right? If so, then it uses the same firmware as Junsun V1 and Hizpo ad907001

Install Device Info HW and it will say so in the system tab.

Vanku PX6 7" 4GB 64GB Radio will not tune, or search.

Hello, I have a Vanku PX6 unit I bought before christmas that I was quite pleased with.
Recently the radio just stopped working. It won't scan or search for stations, tune any presets.
Sometimes it shows a radio station other just a 0.
I have reset apps, done a factory reset, disabled and re-enabled radio in factory settings and power cycled or reset the unit several times.
Does anyone have any suggestions before I send it back?
Thanks in advance

HI, if you have an gps antenna connected near radio antenna disconnect it and see if this is doing interference.

Hi Anton, no I don't think it is an interference issue. It is more like the software stopped talking to the chip.
Thank you for the reply

Get a new firmware from seller and update device or return that device to seller and get full refund if still in warranty or user protection period.

Hi, try to install NavRadio+ if it will work, so it's a software error, if not so it's a hardware error, probably a radio chip. The free version is enough for the test:

Hello, thank you for the advice. It does appear to be a hardware issue.
