Hello. I have Erisin media on one of my cars. After using the rear camera, there is an option to automatically turn on the front camera. On my other car I have Junsun 8667q media but I can't find such a setting. Does anyone know a solution?
[Android Head-Units] gduck:
Yes, but Carletter is the application (in the firmware) that is "always" newer. If not, it doesn't matter. So.. ;)

[Android Head-Units] frost_theone:
I am on FW45.

Android phone - No problem using BT and wire using CARLETTER. There are 2 ways of connection as shown in red circle

IPhone - Only able to use BT. Tried using wire but it didn't work since it indicates BT only (circled in yellow)
[Android Head-Units] mitjama:
Same situation in my case with FW v46. When I was on v39, CarPlay on wire worked.

Did you upgraded FW to v45 or got it by default from the store?
[Android Head-Units] frost_theone:
V45 was already on my radio by default. Tested using original cables too to isolate your issue.

Just curious, Was V39 CarPlay named as CarLetter as well?
[Android Head-Units] mitjama:
It was called CarLetter as well in v39.

It was renamed to CarLink in v46.
[Android Head-Units] lepe76:
My dealer just sent me the UI02 V48 firmware upgrade, the original is V39. I haven't used it yet. I have version 6/128. https://drive.google.com/file/d/1kZBeDMuAEuYlViYUqtvuPJt7f59NbD4k/view?usp=sharing
[Android Head-Units] gduck:
Sorry, but this is not clear for me... Before the connection, how would CarLetter know what kind of phone (Android or iPhone) you have?!
[Android Head-Units] frost_theone:
I hope I get your question correctly.

For the first time, need to manually choose the phone type I have on the bottom left corner indicated in pink. I can toggle between Android and iPhone.

After I exit, it will remember the last phone connected.

Hope this is the information u are looking for 😊
[Android Head-Units] frost_theone:
I see. I saw that you tried to revert v39 but wasn't able to do so. I guess you tried to uninstall your v46 first before installing back v39?
[Android Head-Units] gduck:
Yes, now clear, thank you! ;)
[Android Head-Units] mitjama:
I haven't uninstalled the app. I can try this first if this will be possible. Original app is built into the firmware.

Interestingly, I got an answer from the seller today. He says (if I shorten his answer): Use wireless connection ... Huh

Namely, I would like to use wire, too. If I connect CarPlay wirelessly then I can not use mobile's WiFi hotspot for the radio...
[Android Head-Units] balances89:
I've been trying for more than 4 months, but it doesn't solve anything for me. I think he deceived me...
[Android Head-Units] gduck:
Please send me (in PM) the specification (from the box and the Head Unit) and I will ask ;)
[Android Head-Units] gduck:
Yes this is probably not possible without root...

So, I changed the v39 version number of Carletter so that it can be installed on v48. It will be the same as v48, so once you exit it, the system will "restore" to the original CarLetter version. If it works well, let me know and I'll set the version number a little higher so that you can install it permanently. ;)

Check your PM messages!
[Android Head-Units] gduck:
The update has been completed, the v39 version (with fake version number) works under the old name: Carletter. However, you can no longer choose the wired connection for iPhone. There could be something in the firmware that we don't see...
[Android Head-Units] gduck:
Hi!

Mission accomplished! I got it! The v39! ;) 8667Q军灿UI02-国外-1280x720_v39_20230712.zip

This is a good Manual for T10. But it might be useful in general. ;)
[Android Head-Units] garage battle:
can you do data over usb? my iPhone will do wireless CarPlay and if I also plug the USB in I get ethernet tethering to the deck. I was quite surprised by this.
[Android Head-Units] garage battle:
Hello thread!

Just purchased an 8667 unit 4g/64. I cannot get the unit to find/connect to my ECUTEK BTLE dongle. The stereo can see other bluetooth devices (my phone / living room TV) but pretends that the dongle isnt there. The ECUTEK app doesnt see it either.

Any thoughts?
[Android Head-Units] kitten_lv:
Most probably I could, but that wouldn't be as elegant of a solution. BT tethering is part of Android and I'm confused, why it wouldn't work out of the box for this HU, because a much cheaper competitors HU I had in my previous car had BT Tethering.

I hope for BT tethering and I hope that someone will be able to guide me.
[Android Head-Units] seth_space:
Are you sure your ecutek is not connected to another bluetooth device?

It only supports one connected device.

If so disable/unpair the connection with the other device.

But remember bluetooth is a very messy protocol with lots of different flavors.
[Android Head-Units] kitten_lv:
I'm so sorry, but what is "ecutek"? My Junsun v1 Plus headunit is connected to only to my Samsung S23 Ultra, so one device.
[Android Head-Units] bloot:
Ecutek most probably is an OBDII bluetooth adapter, I find it kind of strange that it is not visible for your head unit, does it appear on your phone?
[Android Head-Units] kitten_lv:
Sorry for the misunderstanding. I'm not trying to connect to a OBDII device. I'm trying to share internet via my phones Bluetooth Tethering, but the headunit doesn't want to receive internet through my phones Bluetooth Tethering. I want to share my phones internet to the Headunit (Junsun v1 Plus) via Bluetooth.
[Android Head-Units] bloot:
Ah sorry, the answers crossed one another, I was referring to the device @garage battle was talking about, for your question, did you enable sharing internet access in the Bluetooth settings? These settings are a bit buried into the system, you can invoke it via OK Google for example (OK Google, open Blutetooth settings). Sorry, I've never shared internet connection via bluetooth and don't know if it is possible in this HU, but I guess there must be a setting for enabling it.

You'll need Google Assistant for OK Google to work. You could also search for bluetooth settings apk in the system but I think the OK Google method will be easier and 100% will work, I did open it this way a while ago.

Google Assistant - Apps on Google Play

Get things done faster and easier

play.google.com

Edit

This is what I was referring to, but I think this must be enabled on the device that shares internet, not in the HU, but you may try anyway
[Android Head-Units] seth_space:
@kitten_lv ,

Sorry responded on the wrong entry.

Was meant for @garage battle
[Android Head-Units] kitten_lv:
Thank you so much, for the extended help. I have Bluetooth Tethering enabled. The problem is that the Junsun v1 Plus, for some reason, is presenting itself as a Bluetooth Headphones/Speaker/Audio device, so I don't have any chance to toggle Bluetooth Internet Access. Nor my phone, nor the HU offers this option. 😭
[Android Head-Units] bloot:
Maybe you can try this https://xdaforums.com/t/share-internet-connection-via-bluetooth.4236823/
[Android Head-Units] Rickavv:
Is there any news? Any luck fixing it?
[Android Head-Units] cursex:
Not yet. Our friends from Junsun told me that they are working on a new firmware to fix it..
[Android Head-Units] kitten_lv:
Oh, I did try this .. and only when this didn't work for me, I became desperate and got the courage to ask for help. I searched the forum far and wide and can't seem to find anything that works. 😭
[Android Head-Units] bloot:
Oh, sorry then, have you tried reaching out your seller for more detailed instructions?
[Android Head-Units] kitten_lv:
Yeah, I did... They said that I can go freak myself, that the HU doesn't support bluetooth internet connection and only works via WiFi tethering. I wouldn't mind wifi tethering, but the thing is, that wifi tethering doesn't work whilst wireless Android Auto is running. The device is the Junsun v1 Plus 8/256GB (FF_866X).
[Android Head-Units] gduck:
LOL! :( Please answer this: "Yes, I'm a smart person, so I know you're lying about the Android version! TERRIBLE!"

PS: I will also try to test the bluetooth internet connection to see if I can figure something out ;)
[Android Head-Units] kitten_lv:
I so appreciate you trying to help and I hope you will succeed. 😻
[Android Head-Units] yakdtai555:
To be Frank, I think many buyers start returning their radio. They are probably fed up already. Lol

The last time I saw the number of Junsun radio sold for my car type on Aliexpress was 180+ units.

Now it is showing 157 units.

From this, we can see everyone knows about Junsun business ethics. Full of lies china company.
[Android Head-Units] kitten_lv:
Unfortunately I wasn't as smart to not fall for the trap. I asked Junsun for a refund, that I want to return the HU, but still waiting for an answer. Made a dispute case through AliExpress customer support. Hoping for the best. Fingers crossed.
[Android Head-Units] yakdtai555:
They will accept refund but they will ask you to pay for shipping first.

They will scrutinise the unit you return, ensuring no damage or dings on the radio before proceeding the refund.

Your shipping payment will probably return through PayPal.
[Android Head-Units] yakdtai555:
As most of us are aware from v39 to v48, there is no form of Android 12 update.

I simply don't understand why they are so adamant to claim that its Android 12.

P.s their bluetooth is not 5.0 as what they claim. Its only 4.xx if u test with 3rd party application
[Android Head-Units] kitten_lv:
It sounds like you have experience with this? Except the film on the screen, that I removed and the carbord box for the frame, that I tossed out, the device is flawless...
[Android Head-Units] kitten_lv:
Bluetooth tethering is available since Bluetooth v2.2 so... I don't mind Android 10, I don't mind Bluetooth v4.xx... I just want the functionality. 🥹
[Android Head-Units] yakdtai555:
Let's see what they propose for your case.

If they really want to sell the unit, they might just compensate you with other things.

Actually the BT on Junsun has limited capability, for instance I think it cannot even bluetooth files from mobile phone to head unit.
[Android Head-Units] gduck:
I wouldn't actually call it a limitation, but a BUG. The bluetooth module is somehow very poorly written. "Funny": JUNSUN ODBII bluetooth adapter cannot connect to JUNSUN HU. (Advertised together with HU!) They promise to fix it, I'll be curious. So there are problems with the bluetooth part. In the next few days I will test it with firmware from different manufacturers, I curious if there is a difference...

I'm afraid that the "error"/limitation is in the MCU and there are not updates for it. :(
[Android Head-Units] kitten_lv:
Yeah, let's keep our fingers crossed. I really hope for a refund.
[Android Head-Units] ossie26:
I advise ideas on how to buy px5 or px6. I have had Junsun myself and I am done with that radio where you can't do anything and when you ask Junsun, they always ask what it is, always your fault or you who did not understand it.

I had my first radio from and px5 never had a problem and I started changing because it was all old and I had no Carplay and couldn't get it via an app and that was only for Android Auto then the ****ty Junsun radio I only had 2 months now cost me me and px6 and it is the best and super good as work according to my wish
[Android Head-Units] gduck:
Unfortunately I have no good news. I tried three different firmware versions, but none of them work:

- XTRON (which has the ID Juncan UI02 v48 and its modified version)

- TENGSHI (which has its own ID, but its core is the same as Juncan UI03 v5)

- JUNSUN (Juncan UI03 v5)

Unfortunately, it looks like the firmware core is being cooked somewhere and the manufacturers are just modifying and adding codes. I couldn't find an 8667 firmware file in which BT internet use would work. :(

I don't know exactly what is in the MCU (ts67.bin), so far I have seen the following:

- G6-TS (220713) - old, but downloadable

- G6-TS (230322) - current, I never seen newer, not downloadable

it has a lot of parameters that can be used to customize the firmware. Some example:

- support_cpu_fan: whether to have fan support

- custom_device_name: device name on the Android about screen

- custom_ver_: HMI: TSKJ.NVG6.D.Q.F.<<THIS>>.2023.07.11.8.34

- support_change_navivolume: two or four volume options:

abrakadabraaaaa :D

So, I can also make small modifications, but unfortunately it is unlikely that I would be able to modify the bluetooth, I don't know enough about that.
[Android Head-Units] seth_space:
The support_change_navivolume: two or four volume options:

That one looks promising.

i often have to turn down the volume to avoid deafness with a navigation notification.

Where to find this option?
[Android Head-Units] gduck:
This is coded in the MainUI. I made this modification in the UI03 v5. Tell me your firmware version number and I'll do it ;)
[Android Head-Units] seth_space:
I am on v43
[Android Head-Units] bloot:
Very interesting, what files should be modified to get the navi and bluetooth volume controls? I extracted the MainUI.apk but there's so many files I got lost :ROFLMAO:
[Android Head-Units] gduck:
Not a simple zip file, do not unzip! :D

res\values\strings.xml

original value:

<string name="support_change_navivolume">0</string>

modified value:

<string name="support_change_navivolume">1</string>
[Android Head-Units] bloot:
Thanks will try it ASAP! Yes MainUI.apk is not unzippable, I used apktool so no problem there.

Edit

I saw this

<string name="support_multi_window">0</string>

Did you try it? Seems to be PiP support?
[Android Head-Units] kitten_lv:
Thank you, oh, so much for your help and that you tried to remedy my hurt... I filed for a refund to them and hope to buy a different headunit, where the seller asures me, that the unit is MUCH better, and I believe him. (I will never learn) :D

I don't think it's 0 in Tenghsi v53, but there is PIP support ;)
[Android Head-Units] bloot:
I modified some parameters and repacked it with apktool but it didn't want to install, I guess I need to sign the apk but have no idea how, will try to find out.
[Android Head-Units] gduck:

[Android Head-Units] gduck:
Yes, this is the other "line", it's more customizable, I think it's actually better ;) Good luck!

Topic link
[Android Head-Units] balances89:
I send you a private message
[Android Head-Units] gduck:
Well, my PIP project and hope are returned :D

I brought up the topic again because I found some settings while analyzing the MainUI.

Now I'm using firmware 8667Q军灿UI03-车模--1280x720_v5_20240113.zip, which had to be changed in the MainUI because the open door warning didn't work. Then I wanted to enable the navigation volume control, so I started analyzing the MainUIs in other firmwares.

This is how I saw a few settings with which I started to "play" and modify the v5 MainUI :)

"support_change_navivolume": the navigation volume control appeared for this, but as it turned out, it does not control anything. I'm still investigating this matter...

"support_freeform_mode", "support_multi_window" (thank you for

bloot ;) ): I enabled these in case it helps with PIP. Note: only the "support_freeform_mode" was enabled in Tengshi firmware.

The result:

base fimware: 8667Q军灿UI03-车模--1280x720_v5_20240113.zip

+ modified v5 MainUI (only for "8667Q军灿UI03-车模--1280x720_v5"!)

+ Tengshi 8667TsLauncher3_ts05_1280x720.apk launcher (from Tengshi v53 firmware. File is attached.)

Now, I have two selectable Launcher: "Launcher" is the orignal JUNSUN and "Launcher3" is the Tengshi launcher.

And now, the hope is returned. :) This "configuration" is working since three days, without any problem. :) For the driving, I'm using Magic Earth Navigation (you can see in the picture), because it follows the route. For the navigation, I'm using the built-in Google Maps.
[Android Head-Units] bloot:
Many thanks! Will try the Tengshi launcher you are sharing, I am a total denial and cannot get my modified MainUI.apk to install in my HU, no matter how I sign it, or zipalign it, it just won't install :(

[Android Head-Units] frost_theone:
@gduck thanks for sharing. 😊😊

1. So I guess you are using Junsun v5 firmware as your main launcher since Tenshi Launcher doesn't indicate doors opening?

2. Since you enabled PIP in Junsun main ui FW v5, Tenshi launcher has no problem displaying Google map at all. So if i am still using the v45 or v46 FW and plan to use Tenshi Launcher, I am still going to face the PIP glitch unless I modify the PIP setting. Am I right?
[Android Head-Units] limsheng:
Hi, I just came back from my car and finally got the full screen. The solution was really that simple.

I used E-sys to code the resolution.

And that’s that! I can’t believe other coding apps can’t do it but only E-sys. Haha
[Android Head-Units] gduck:
1. NO! The original v5 does not indicate when the door is opened! The modified v5 MainUI fixes this bug! ;) I use the Tengshi launcher because it has PIP support and thus the original JUNSUN launcher is available ;)

2. In fact, YES. When I tried with v46, I always had a PIP error the next day.

Hello,

i installed correctly this version :

8667Q军灿UI02-国外-1280x720_v48_20231201

But impossible to install this version :

8667Q军灿UI03-车模--1280x720_v5_20240113

At the end of the install i'm blocked on "Fastboot mode..."

Do you have an idea why i have this ?

Thanks :)
[Android Head-Units] gduck:
What is the head unit type? I've swapped back the firmware versions about 30 times, but I had no problems...

What happened? Does the v5 update happen 100% and doesn't it start again?
[Android Head-Units] Sama41:
I don't know really, it's not a Junsun but i think it's the same...

It's a Hizpo Head Unit with a 8667Q processor

V5 starts to install but at the end, i'm blocked with "fastboot mode..." , I have to force restart.

After reboot I automatically revert to my old firmware with all data retained
[Android Head-Units] 14r33k:
Are you sure? Hizpo usually have a UIS7862, not 8667Q
[Android Head-Units] gduck:
If it works with 8667Q v48, the CPU type is indeed 8667Q...

"After reboot I automatically revert to my old firmware"

In this case it won't even start the update... Am I right?

An update process:

1. Restart

2. MD5 hash check 2-3 minutes

3. update process 2-3 minutes

4. clear all data

5. Restart

6. DONE

How far can you go?
[Android Head-Units] garage battle:
bringing this back up as the responses got sidetracked. my iPhone can see the ECUTEK btle dongle but the Junsun deck doesn't see it / the installed ECUTEK app on the Junsun doesn't either.
[Android Head-Units] gduck:
You have the LATEST firmware on your HU. ;) (Which is publicly available). CAN setting depends on the type of CAN adapter. What is the type of CAN adapter?

If your CAN adapter type is the SimpleSoft (Xp), the current setting 117 is OK for you. Choose the first one (Renaul, Duster), unfortunately few things will work.

117 Renault (Xp):

- Renault, Duster

- Renault, Duster (AVM)

- Dacia Duster

- LADA VESTA

- Renault Fluence

You can check the firmware file number with code 160 on the gear icon.

If you have 8667Q军灿UI03-车模--1280x720_v5_20240113 (99%):

This version does not indicate when the door is opened (bug)! The modified v5 MainUI lot of times fixes this bug! ;) You can try, if you would like, but it didn't work for anyone else with a Clio 3 2008 model... Since v5 is the original firmware for you, unfortunately it is not possible to know whether this is a know v5 bug or a limitation of your CAN adapter.

"If your open door warning disappeared after the v5 update, install this patch. Download (slow download is cost free), unzip and install the apk ;)"
[Android Head-Units] wybitny2:
I wrote to Junsun, I wanted to obtain software like the one in the photo, they wrote to me that they do not have such software for my radio - the 8667Q processor. Does anyone have software like the one in the photo with such a function? . They described to me that this software is only available for the UIS processor. I wonder why they advertise something that is not available in a given processor. Or maybe that's why there's an ad telling you to buy a newer radio.
[Android Head-Units] gduck:
This looks like v5: 8667Q军灿UI03-车模--1280x720_v5_20240113.zip

More information about UI03 v5, please read this ;)

But the proximity alarm display may depend on the car and CAN type (I think), I have not seen such a picture yet with proximity alarm...

PS: looking through the v5 MainUI source, I didn't see such red car and triangle images. So, very similar, but probably really made for a different CPU/HU type. (for example JUNSUN X7)
[Android Head-Units] wybitny2:
I also looked through the software and also realized that it's crap, that's why I'm asking
[Android Head-Units] wybitny2:
Maybe there is someone here who knows how to connect to a computer via ADB, in older software it was possible to do this, I will share the information what I have, but I need to get an answer about how to connect to a computer via ADB.
[Android Head-Units] SteeveGr:
V5 and V46 contain this warning which is related to CANBus of BMW or Iveco cars.

So probably it has to do with the CANBus information of specific cars .
[Android Head-Units] garage battle:
deleted - silly issue
[Android Head-Units] Sama41:
Yes i'm sure it's a 8667Q processor :)

This is strange because the update start, i have no error message but after maybe 8 minutes, i have "fastboot mode..."

I force a restart of the head unit and it starts without problem on my last firmware with all datas... but not on the new firmware.

I have this problem only with the firmware v5_20240113. Not with others firmwares...
[Android Head-Units] gduck:
