Front camera on Joying JY-UL135 - Android 5.1.1

Hello guys,
I have a huge deal trying to implement the front camera on Joying JY-UL135.
I have allready the rear RCA camera installed, and it works great with the reverse gear.
I've connected the front camera on the AV-IN, and it works when I use SRC button on AV-IN, but I want it to work as a front camera, so I've activated it in "Factory Settings Menu", but it shows me a yellow ! sign, and no way to make it work.
I've asked Joying, but no good answer. :crying:
Is it possible to make it work somehow? Maybe by flashing with a compatible MCU? which will handle it as Front Camera and not AV-IN?
Thank you,
Cheers,

Front Cam
Did you power the front camera beside's using the RCA.

Damit17, not yet.. this is what i was thinking about... but from 4pda forum, it seems that F-CAM RCA and AV-IN are differnt.
Is it same input? did you tried it?

Post MCU and Android version in [about] so we know which unit you have. Model numbers are almost meaningless.

Thanks marchnz.
My problem is, Joying does not support officially front cam. The unit has only AV-IN.

Would this be because Joying expect the front camera to be a USB camera/DVR as listed in the wiring diagram? The AV input wasnt intended for front camera operation; this is for DVD players, DVB-T TV tuners etc.
Unless there is a way to assign the AV input via [Factory Settings Menu]?

Hi, maybe something like this may help - Car Parking Camera Video 2 Channel Converter Auto Switch Front /Side/Rearview Rear View Camera Video Control Box with Manual
I have no experience with this unit but tempted to look into a solution like this.

did you ever get this to work?

F-CAM app does not work for me either for rear cam... It shows yellow ! sign... I have a Seicane PX3 android head unit.

My mtcd unit has a front camera RCA input and an F-CAM power connector. F-CAM app and front camera work out of box with this unit.
If you don't have these connectors and are interested in getting F-CAM to work, follow this thread:

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 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.

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)

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?

Front Camera (RCA) app needed for Topway TS9 android head unit

Hi, all. New to the forum.
I have a KUNFINE head-unit which appears to be based on the Topway TS9. It has multiple RCA video inputs, one of which is labeled front camera, but I do not appear to have an app installed that can make use of it.
Ideally, I'd like to install an AHD cam in the front and use that with a DVR software. Searches only turn up USB cam apps, but the vendor advised me that it is possible to use the F-Cam input for that. I just don't know where to get the right app.

I have a KUNFINE head-unit, I think it's a Topway too. I just looked though my settings and do not see that option. I had planned on adding a front camera but had not looked for it yet, since I have been dealing with other issues. What system version does your head-unit have?

"REAKOSOUND" 9" head unit no sound from any app

Hi, I got a "REAKOSOUND" 9" head unit for my 2005 Citroen C4 Coupe, it has "android 10" or an imitation of it. I have no sound coming from the device (tried Youtube, radio, music app, and others. I manly want the main radio cable connection for sound, not RCA although I have tested the RCA connections which have no sound either.
What I tried:
- Reconnected wires multiple times
- Hard reset more than 3 times
- Seller provided "update" that did not change anything
- Tried an RCA speaker into RCA "Aux R Out" - no sound at all (Speaker from a 5.1 PC speaker set)
- Oscilloscope measured from the CANBUS/radio harnes from one speaker line coming out the head unit: 60Hz sine wave less than a millivolt, think that means no sound coming out the Head unit output.
- Tried all avaliable CAN Type options for citroen, steering wheel buttons work with all of them, no sound with any of them.
- Volume has been set to max "40 units".
- Original radio still works.
- Tried to look for some apps on google play that may control sound output, found only one, did not do anything.
- Tried all the apps: Radio, Music app, BT music, Aux mode, Spotify, Youtube, phone call (mic works) - no sound output from any app.
- Canbus works, the steering wheel buttons work and travel distance data is being transmitted to the head unit.
- Tried asking for OS update files from other Ali sellers, all refused to share (not compatible and such).
What I noticed:
- All the Citroen Canbus models in the head unit settings have 2008-2015 models, the ad said compatible with 2004-2008 car models - maybe the Canbus is incorrect for my car (I have Raise PSA-RZ-15)?
- There is no AMP wire coming from the cars side.
- There are no audio settings in the Head unit, Only an equalizer and a balance setting front to back and left to right, that's it. Other head units seem to have more options in the OS.
My Questions:
1. Should audio work without CANBUS?
2. If there is an amp in my car and it communicates with CANBUS, can I turn it on without canbus? (I have not seen an AMP wire in my car - nothing blue with a white stripe or similar)
3. Does anyone have any suggestions what to try to get any sound?
4. Are there any other car androids I could install and test?
a. (EDIT: I found this post on XDA, and this post, and this post, as far as I understand there is an MCU and a MTCD, one of them carries android the other is like bios that bridges the car system to the android, in my case, the sound issue could be from either of them)
5. If it's not android, what hardware should I check? I am decent with soldering and similar electronics, just Head Units are new to me.
Device info that I could find:

Hi new member, posting in MTCD general forum.
Is it an MTCD/E device?

Thank you for the response. I improved the format, hope it helps. I unfortunately don't know what MTCD/E means, I did not find anything on google. Therefore I am not sure if I have an MTCD/E device. I am familiar with electronics but head units are new to me. My first experience with them has been severely disappointing. Hope I can get this unit working and learn something along the way.
What does MTCD/E mean and how do I know what device I have?
If I am in the wrong place, is there a better sub forum on XDA I can post my question to?

Hi, I have requested a Mod moves to [Android Head-units] forum.
Your post is likely to have visibility there. You'll also find your device listed/discussed there - mcu version.

I doesn´t make sense to just guess... If we know the unit, we could find something.

This Head Unit not a Topway platform, so password be not 7890, It's look like FYT platform, maybe take some system info can easier to judge

I thought something like that as I saw your desktop with the buttons on top.
We are talking about a Klyde derivative, with some different things inside.
Now it´s clear, this is a RL9Ac, so my expectation was correct.
There are only 2 PINS available in this unit:
7890 is the first one to enter the system information
8861 for deeper settings menue
There is nothing else.

possible that it is so lacking in options? when the px6 is also too full of options to set

This unit is so different from the ones you seem to use...
All options are available with these 2 Pins. There is no need for any other settings page.
Edit:
The RL9Ac are the pendants to the rotatable screen used in Klyde KD-1280, which are delivered with the RL7Ac MCU. The main setup menu is the complete same in both.
There are already some threads in this forum. Just some guys don´t understand this unit and the features with it.
It´s completely different from all other currently available unit.

this radio has two RCA connectors with written VIDEO IN and S. CAM IN in yellow color ..... I wanted to connect a front camera with RCA connector .... but then how do I select it on the screen?

Well... If you want that the front cam act like a dash cam... no, that doesn´t work.
If you want to have the front cam acting as a parking cam, you can activate that in the settings and it would be activated for some sec. after you leave the reverse gear.

no for the dash cam I have already ordered a dash cam to be connected to usb .... I also bought a simple camera to be inserted in the front grill but it is rca .... I do not have the icon on the screen to activate it .... that's the problem

the radio being specific for the captiva is all plug & play .... but there are some scattered wires that the Chinese say should not be connected .... I am attaching photos .... I had number 5 translated and it is "camera power" but I don't know if it refers to a possible front camera to be powered .... the camera behind the machine works without problems and without using any rca connector.

For front camera i have buy this.... I not want that use like dvr or dash camera..... Only parking camera

My car have front and rear parking sensor
