I’m referring to the metal piece in your first picture. Slide that metal piece back and lift it up, then place the SIM contact side down and close the metal piece again.
[FYT Android Head Units] CZ Eddie:
Whoah, that was far from obvious!

Slide the metal clip up (away from the cable) and lift it open.

No wonder the SIM didn't want to go in nicely.

It took my Google SIM right away and set it to a T-Mobile APN.

Service is generally poor at my house but I'm not too happy with connectivity ATM.

Turns out the Joying doesn't get Band 12 (I think) which is all I get at my house.
[FYT Android Head Units] abbyme24:
Yeah the bands are limited. I have t-mobile which is primarily Band 2 and Band 5 and the Joying only has Band 2. Luckily that is the “base” for T-Mobile’s network so the coverage is pretty good overall. Sucks you don’t get Band 2 at your place.
[FYT Android Head Units] credo@unforgiven:

My car is Adui a3 8P 2004 r.

I connected the relay, the voltage from the backlight bulb turns on the relay which gives 12v from the power supply of the radio antenna and gives it to the reverse signal. Everything works now.
[FYT Android Head Units] PsychoMcSatan:
Still looking to set DPI at time of ROM install and Googling has uncovered that editing the line ro.sf.lcd_density=x (where x is desired DPI) in build.prop should do the trick, but I don't see build.prop in the Joying ROM files. That line looks similar to others in config.txt files so wondering if this command can be added there, but looking for confirmation on what exactly config.txt is and how it's applied.
[FYT Android Head Units] stormrider57:
the seller give me the entire rom (full) and there is a lot of syu and fyt files in it.

Joying units are manufactured by an outfit called "Carsql" aka "SYU", which is now owned by the manufacturer of the SoM, "FYT". They (SYU/SQL/FYT) have a lot of customers that they manufacture radios for, INCLUDING Joying, and likely yours as well. Usually, the MCU is tagged with the customer ID.

I searched this thread for keyword "slow" but didn't find anything.

Is anyone else experiencing extremely slow Google Play Services?

App installs take foreverrrr to start downloading and the download itself is really slow too.

I somehow accidentally reset back to factory defaults after a Joying Extra Tools mod gone wrong.

And still have super slow Google services.

Tried changing DNS to 8.8.8.8 and it's still slow.

I'm on the latest 6/21 firmware.

My WiFi is blazing at 60Mb down / 10mb up.

Chrome works fine surfing the Internet.
[FYT Android Head Units] CZ Eddie:
I just upgraded to the "BETA" Google Play Services.

And so far, so good. :good:

EDIT: Nope, nevermind. I got one app that downloaded fast. The very next app download is back to super slow speeds.

argh

EDIT 2: I wiped data from everything Google related. Got one really fast app download. Then the next download was again back to really slow.

Frustrating. I can't even get this Joying off my bench to install it in the car. I've never had an issue like this with any of my ~20 phones, tablets & other devices over the last few years.

hello, i did everything like in "tne readme folder" but it does not work ??

patched with magisk etc.... the only difference is , my "patched boot img" was "called magisk patched" and when i check with magisk it says magisk is not installed !

For info, i used my boot img from my stock rom (sinosmart)
[FYT Android Head Units] bambapin:
You have to rename the "Magisk patched boot" to "patched_boot" and then following all the next steps explained in the readme (put the patched IMG inside the input zip, start.bat and so on).

Indeed, you know that the procedure has been tested only on the latest Joying units and that can be potentially dangerous on different headunits?

[FYT Android Head Units] stormrider57:
yes i know, this can be dangerous, i tried a ready patch from 4pda forum i was rooted, but i had a red chinese, message at the top of the screen.

done , im rooted ,:) i installed the joying extra tools, and tried for another radio apk but it does not work after rebooting, still the same radio apk its a nice one ,but the RDS TEXT is to small.
[FYT Android Head Units] CZ Eddie:
My rearview camera gives "No Signal" on the Joying.

But works fine when its RCA is connected to my AV Receiver and computer monitor.

I do have the "back" wire connected, which is why Joying changes to the backup view. It just isn't understanding or detecting a signal?

Is there a special setting I need to configure for this?

I'm on a new, reset to factory defaults, 6/21 firmware version.

My Odroid XU4 Android board see's it just fine.

Joying just referred me to their blog about hooking up backup cameras, which I already told them I followed.

EDIT:

I'm a dork. I didn't realize there were two different video inputs. One on the deck (that I was trying to use) and one on the harness (that I should have been using). Backup camera works fine when you use the correct input.
[FYT Android Head Units] PsychoMcSatan:
After a couple hours of tinkering, I believe that ADB over WiFi on these units isn't possible without rooting. [MENTION=2550900]surfer63[/MENTION] 's suggestion to add persist.adb.tcp.port=5555 to config.txt does allow a connection (after USB debugging enabled on the Joying), but there doesn't appear to be a way to authorize the PC's connection so no commands are accepted. Looked into copying over ADB_KEYS, but root is required.

And I tried adding "ro.sf.lcd_density=200" to config.txt to try to install the ROM with different DPI, but that doesn't seem to work. No apparent ill effects though.

Also, I earlier had troubles regaining Google Voice after rooting then uninstalling Magisk. So it turns out that after uninstalling Magisk, I discovered Magisk still installed. When I started it up I got a message along the lines of "Full version required to complete previous action", clicking okay downloaded some more files and then rerunning uninstall did the trick and I'm back to normal with Google Assistant talking back to me.

So I feel my unit is pretty much where I want it and likely no more tinkering... except maybe adding a fan... or if a new ROM comes out with new features to try.
[FYT Android Head Units] bambapin:
Maybe the radio apk is different in your rom. Try to look for the name of the radio app in the list of installed apps.

[FYT Android Head Units] davemazo:
Is anybody else having problems making calls on this unit. When I say ok Google, the assistant pops up, I say "call X" and all I get back is "sorry I can't do that yet". My contacts have been uploaded to the head unit and work if I say "show me my contacts list" . I can then press the contact I want and the call is made. That though is not the safest way to do it
[FYT Android Head Units] CZ Eddie:
I haven't messed with calling yet.

Have you given the app permission to access the contacts?
[FYT Android Head Units] bambapin:
As far as i know, Google assistant phone calls are not yet wordlwide available, do they work on your phone?
[FYT Android Head Units] surfer63:
On the Sofias and PX5s we always needed the "GVC Callhandler 4 Joying".

I can't say anything about the intel Airmonts, but you might give it a try.

And lately I use Bestee, as I want to get away from Google as far as possible.

I'm not convinced yet as it crashes a lot on my PX5, but I can make calls. And Play store says my unit is not compatible, so I installed in on my phone and copied it off using Total Commander.
[FYT Android Head Units] davemazo:
Thanks CZ Eddie

I'm sure I have enabled access but I'll check later

Bambapin

Thanks, I used to be able to. I've just checked my Note 8 with android 9 and I couldn't. I retrained the phone and now at least the phone is working, I'll see if it has affected the head unit later when I get a chance

Thanks surfer63

I have installed GVC call handler. Maybe I've not told the unit to use the app to make the calls. Again, when I get a chance I'll investigate later

Thanks all
[FYT Android Head Units] PsychoMcSatan:
Google won't forward on the call request if your DPI is at 160 (perhaps it thinks you have a tablet and not a phone?). I've confirmed that 161 works. The Airmont didn't seem to need the GVC Call Handler at first, but functionality became spotty. It seems flawless now that I installed it. I think it removes certain character combinations that the Joying bluetooth app doesn't handle well.

Also, to point calls to the GVC Call Handler app (or Joying app), I believe you need to first use the Google app and press the microphone icon, which then presents the option for you to choose what app to make calls when you say "call whomever". OK Google doesn't give you that setup option, but once set, OK Google should work.

Found the post where I got most of my info... and there's a video too:

Call handler

Thanks for that. I did see that and gave it a go but for some reason I didn't have the same options or items to tap as shown in the video. I'll have another look though.

I believe I need to root to change the dpi to 161. I'm a bit wary of rooting and bricking the unit. It's something I don't fully understand.
[FYT Android Head Units] hillbicks:
So, after a lot of trial and error I got sound working on my headunit (My car needs an additional DSP adapter for the cars amplifier). Next thing is debug the steering control adapter.

In the couple of hours that I tried it I noticed one thing. While using waze, street names and such on the map look really bad. Anybody else notice that? I guess I'll try to change the DPI and see if that makes any difference.
[FYT Android Head Units] maoyaotang:
I've just updated version 9.0 and I don't feel much different. I am the Chinese version.
[FYT Android Head Units] davemazo:
With regard to making calls using "OK Google" I think I'm getting somewhere. I found that Google hadn't synced my contacts to the head unit. I can now make calls, the call screen briefly appears but then reverts to the home screen and the call is handled by my phone but plays through the car speakers, if that makes sense
[FYT Android Head Units] PsychoMcSatan:
So did you change your DPI? If you're getting the Joying bluetooth-dialer app to popup, then you're definitely close. I was having similar behavior till I installed the GVC Call Handler app (in Play store). It was developed for earlier Joying units to smoothly hand off call requests to Joying's app. It appears all Joying's have the same bluetooth-dialer so it works on this unit as well.

Actually, it sounds like it may be working as it should. Your phone is making the calls so you will see it's Phone app startup. However, audio should be handled by the Joying microphone and speakers.

Cellular Data connection issues

Hello - new member here. I just installed one of the Joying Airmont units ( JY-TO158N4GS) in my Lexus GX470. Love everything about it, except I can't get the cellular data connection to work.

I've installed the SIM in the dongle, and it shows as connected in notification area (4 bars) but I cannot access the internet through any apps (Maps, google play, chrome). They all say the unit is offline. I can get wifi access when I am at home, but no cellular.

I've reached out to Joying and their advice was to reinstall the SIM and reset the unit. I tried that, no change.

Thanks in advance for any advice on things to try, I am guessing there is some setting I am missing.

----------------------------------------------------------------------------------------------------------------------------

Scratch all that.... Turns out that I am an idiot, as the issue was that the SIM needed to be activated. All the docs on AT&T website said no activation needed - but I had to call and give them the IMEI. Up and running now. Not great speed, but I can use maps and stream music.
[FYT Android Head Units] Mlsaab:
Who's the carrier? If tmobile the sim needs to be set as a tablet. Their sync up only works with their dongle.
[FYT Android Head Units] davemazo:
I haven't changed my dpi no. I can't find that option, maybe because I'm not rooted and not too sure how to do it.

The Joying bluetooth app doesn't pop up, it goes straight from the Google Assistant back to the home screen despite the GVC Call Handler app set as default call handler. It does seem to be working after a fashion though
[FYT Android Head Units] bambapin:
It is possibile that the Google Assistant on the headunit routes the call directly to the phone (as if the headunit were a Google Home) and doesn't treat the headunit like a bluetooth headset to start the call.

This feature is available (on Google Homes) certainly in the US but not yet for all countries/languages. Where are you from?
[FYT Android Head Units] Cr4z33:
I am using Headunit Reloaded with one of these units and using Google Assistant to call somebody is working good so far.

Maybe youre right i found this :

[FYT Android Head Units] julien_blanche:
Lets create a list for remaining issues after 2019.6.21 update;

1- Head unit initiates gmail contacts to be deleted (sync)

2- Status bar background color (background is transparent and icons & text are white, so when you open an app with white background you can not see anything in the status bar)

3- Spotify, Youtube or any last program auto starts always

4- Dimmer option for the side touch panel buttons (it is too bright at nights)

anybody to contribute to above list would be much appropriated so we can send it to the joying cause it seems that they are stopped producing solutions...

cheers..
[FYT Android Head Units] surfer63:
This bug already exists since Android 6.0.1 on the Intel Sofias. That is more than 2 ~2½ years now. Lots of posts here, on their old carjoying forum and now also on their new forum-joyingauto.com forum.

The first year Joying did not even want to recognize it until john Molberg made a video of it.

But it is still not solved. So many (open source) contacts apps on F-droid and in the play store. And open source on github and the google archives, and they still can't fix it. :rolleyes:

Edit: I made a "read-only" BT app about a year ago for the PX5. The BT-app has "android.permission.READ_CONTACTS" and "android.permission.WRITE_CONTACTS" in the AndroidManifest. I removed the "WRITE" authorization.

There is also a simple work-around, but it shouldn't be necessary.

After firmware flash:

Go to Settings

go to user account -> account sync

disable sync (of contacts)

couple phone via bluetooth

download contacts

Never switch on the sync
[FYT Android Head Units] julien_blanche:
Thanks for you detailed answer very much appropriate, since this problem does not exist on non-joying px5/px6 platforms i thought it could be solvable but it seems they over sighted this issue for a while.
[FYT Android Head Units] surfer63:
Off course it should be solvable :)

They simply don't seem to be able to do that.
[FYT Android Head Units] thierry34:
point 2 : is there an option to close the screen (screen black) but application music always work. it's useful for the night. on my pioneer unit, i have this option. when i drive by night, i turn off screen but the music always play. i haven't light in my car.

i ordered my joying unit tochange my pioneer unit. i hope there is a solution for that.
[FYT Android Head Units] surfer63:
On the Sofia units there was: hold the power/volume button 10 seconds. That doesn't work on the PX5 units. No idea about the intel airmonts.

Otherwise there are a multitude of "black screen" apps in play store. Touch app icon: black; touch screen again: and there shall be light.
[FYT Android Head Units] hillbicks:
Does anybody else have the problem with the sound level when turning on the ignition? Since the music starts to play once the head unit is turned back on again, it seems that the sound level of my car is suddenly maxed out, even though it wasn't before I turned the ignition off. Normally I would say that this is not related to the head unit, but I did not have that problem with the aftermarket radio I had before.
[FYT Android Head Units] DustoMan:
The setting you are looking for is "default boot volume" under the General settings. . I had to turn mine way down.
[FYT Android Head Units] rigattoni:
They are most likely set to a boot volume of 18...

Had to reduce it to 6 to not get a heart attach... :)
[FYT Android Head Units] kuku2004:
Some more problems I have encountered:

1. When Google voice is activated people on the other side of the call can't hear me at all. When it is disabled they can hear me.

2. Spotify swc is working only with old versions of Spotify from 2018 (canbus).

3. "slow" voice in Google maps and waze after rooting.
[FYT Android Head Units] hillbicks:
That was my first thought as well. But I'm not even talking about a cold boot, just turning the ignition off and directly on again results in the volume being increased. The volume of the head unit stays the same though. That's why I doubt that it is related to the head unit, but you never know with these things......

I just tried it again with the volume on 6 on the joying, the volume level of the car is increased, not on the joying.
[FYT Android Head Units] CZ Eddie:
I wired up the dimmer wire to my vehicles dimmer wire. But nothing happens on the joying when I turn on my headlights?

Hi all,

Hoping you can help as Joying support is proving to be quite useless unfortunately.

The bluetooth quality of phone calls is very poor in my car with my SC98 on latest firmware.

Sound in my end sounds distorted as when you increase the gain way way too much on a signal.

On very low volume levels like 5-6 where I can barely hear the other end of the conversation, the "clipping"/distortion starts happening.

The receiving end seems to hear me rather fine.

Strange thing is that when I play music via bluetooth, the quality is superb.

I have a high-end external microphone connected but am unsure if the HU uses the internal or external one.

I have this issue with both my Oneplus 5T and an iPhone 7.

Br,

Phatty
[FYT Android Head Units] kuku2004:
Joying support claims the latest firmware solves the issue other side on call can't hear you when Google voice assistant is activated, can anyone confirm this?
[FYT Android Head Units] hillbicks:
Anybody ever have the issue where the head unit pulls so much juice that the car won't start anymore? Just had that happen to me.

My understanding was the head unit goes into sleep mode once you turn off the ignition and completely shuts off once a battery threshold is met in order to preserve enough energy to still start the car.
[FYT Android Head Units] edcam33:
With the May update I had to turn off Google permission to microphone as caller was not hearing me. So update did not solve this issue, at least in my case. Not sure about others if they also have the same issue.
[FYT Android Head Units] tangcla:
Hmm, I'll have to check that on mine. So you went to settings / app permissions for Google to disable it?
[FYT Android Head Units] edcam33:
Yes Google app permission , turn off microphone permission. That was the only way for me that caller could hear me over Bluetooth.

Google applications eventually lose internet access after rooting

Hello. I have one of these devices and I recently rooted it using the instructions on xda. I have noticed that since rooting, my device regularly loses internet access in some Google applications. I've noticed it so far in the Google app as well as Chrome.

Curiously, Google Maps works just fine. I know that it is accessing the internet because the traffic information is downloaded each time I program a route. The Play Store is also able to access the internet because I was able to find and download/install Firefox through the Play Store. It was able to access the internet just fine after installing. So, it's not a global problem. Seems only to be happening in Google apps and even then only certain Google apps.

If I reboot my head unit, Chrome works fine and has no issues. But eventually, it will lose its ability to access the internet. I've not noticed any patterns as to when it might lose access. Is anyone else who is rooted experiencing this issue? Thank you.

Brian
