For Mtk8257 users:

I prepared a version of MainUI which allows to re-configure SWC keys via a mapping file. This allows to remap the keys even if a CAN box is in place. Let me know if you want to try.

For 8667 users the same is possible but requires to test the replacement of MainUI with an updater app. Looking forward getting contacted by some testers...
[Android Head-Units] TorstenH:
Interesting is the "CanNative" message. Are you getting other CanNative message when long pressing the SWC mode key?

Anyone know the code for enabling developer options? It isn't 000000 which is the only code in the manual. I've only tried that and 123456. I've heard it might possibly be 8878 or some combination plus the digits on the hour of the 24 hour clock.

Hello, please help. In the Junsun V1 4GB/64GB head unit, the Install menu is off in the settings. When I want to turn it on, you ask for a code. Does anyone know this code to turn on? Thank you very much!

Good morning ! Hello everybody

I bought a Junsun v1 plus 6g 128 gb jand almost everything works except the front sensors. If they detect an obstacle, there is only a sound signal, but there is no visualization of the sensors' operation. Rear sensors work properly with visualization. Is it set somewhere in the system?

I messaged Junsun/Awesafe and they told me. It's the Year, month and day of whenever you're using it in this format: 2023.06.30. You must use the dots.

@buzzywuzzy

Hi, friend,

I need to enter the developers menu, I thought the code would be 000000 but that is for factory settings. I need to enter the developer menu but I can't get into it.

I have seen that I think you have been able to access it. I need you to tell me how you did it...

Supposedly you have to enter the date in the following format: 2023.07.03 or 2023.03.07, I did it but none of it worked.

My radio only admits a maximum of 6 numbers and I don't know how to put the code in.

All the best
[Android Head-Units] buzzywuzzy:
Could you give me a picture of what your screen looks like when you try to input the code? It's not the same screen where you enter six digits like factory settings for me. Also, you may have a different model.

Have you tried 7890 and then for the last two digits, the current hour according to a 24 hour clock? So like, if it's 2pm the code would be 789014. Try that?
[Android Head-Units] fgarlam:
This is the screen to access the factory setting menu

And there is the information about the version of my radio

That is all the information I can offer you.

A question. Do I have to have the 24-hour format active in the android settings?

I will try to try with the code you posted.

Thanks for answering.
[Android Head-Units] buzzywuzzy:
So at least for my device, that screen is not where you access developer options. That screen only works with 000000 for tweaking other settings. For developer options, you have to navigate to Android Settings like normal -> About -> Tap on Build Number 5 times and screen should popup asking for a password. That's where you have to put 2023.XX.YY with XX being the MONTH including the zero for a single digit month (07 for July) and YY being the day, with a zero for a single digit day (03 for the third). You also MUST put the dots inbetween them like shown.
[Android Head-Units] fgarlam:
Thank you very much for your reply.

Finally I could access the developer menu but there was no option to adjust the rear camera.

I remain convinced that the problem is in the configuration of the video signal of the rear camera and that I need some secret code to access some menu and be able to adjust it.

Unfortunately, currently the only code that works is the factory setting with the 000000, but there is no option for the rear camera menu.

If you have any other ideas, I’d appreciate it.

Buenas tardes TorstenH, tengo una junsun V1 Pro y tengo dos dudas. Una es que no tiene acceso al menú de android, imagino que tendra acceso con un código o toques y la otra que cuando entre con el código 8888 en erase all content, no hace un hard reset completo.

Me puedes echar un cable?

Gracias de antemano.

[Android Head-Units] TorstenH:
If you modify a setting via 8888 or 8878 some of your head units settings get erased (equalizer, radio stations,...).

Please let me know which model you're using. 8878 or MTK825X?

Hi lads.

I would need help. I have a 2/32GB Junsun V1 Pro Car Radio. I bought it 6 months ago and the bluetooth does not work. I click the bluetooth app in the radio then click the search the circle just spins and spins, but it doesn't find any devices (I try ios and android) Car Settings --- Extra Setting tipping (123456 pass) and choice --- Config info after BC6 the bluetooth maybe (Junsun France store tell me). I'll select it when I exit, then it won't save the settings.

Maybe hard reset and all data wipe solves the problem if yes whats the setting code?

I can't even select the logo of the car because it's not in the list ( Suzuki Swift 2009)
[Android Head-Units] niconoel:
hello, do you know the code for here?
[Android Head-Units] DDavid95:
Hi. No. My menu is different. I try the 8888 code but not work. Just 123456.

[Android Head-Units] niconoel:
Here is what I have when I go to this on-board computer part.
[Android Head-Units] TorstenH:
Result of a quick look into the coding:

For me this looks not like a code which needs to be entered.

If you enter a number > 3000 it gets used as parameter for the library method PSASetDis:

public void onOK(String str, int i, int i2) {
int i3 = 3000;
if (i <= 3000) {
i3 = i;
}
CanJni.PSASetDis(i3);
}

public class CanJni {
static {
System.loadLibrary("can59");
}

SetDis may be short for set distance.

PSA means: https://en.m.wikipedia.org/wiki/PSA_Group
[Android Head-Units] TorstenH:
Here we can see the calculation logic for consumption, range and speed:

protected String GetConsumpVal(int i, int i2) {
if (-1 == i) {
return "--.-";
}
float f = ((float) i) * 0.1f;
if (i != 0) {
float f2;
if (i2 == 0) {
f2 = 100.0f;
} else if (i2 != 1) {
if (i2 == 2) {
f2 = 282.35f;
}
}
f = f2 / f;
}
return String.format("%.1f", new Object[]{Float.valueOf(f)});
}

protected String GetRangeVal(int i, int i2) {
if (-1 == i) {
return "----";
}
if (2 == i2) {
i = (int) (((float) i) * 0.62137f);
}
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("");
stringBuilder.append(i);
return stringBuilder.toString();
}

protected String GetSpeedVal(int i, int i2) {
if (-1 == i) {
return "---";
}
if (2 == i2) {
i = (int) (((float) i) * 0.62137f);
}
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.append("");
stringBuilder.append(i);
return stringBuilder.toString();
}
[Android Head-Units] TorstenH:
And even more interesting the hard coded units.

Consumption values can be reported as gallons, l/100 and km/l:

protected String GetConsumpDW(int i) {
return i != 0 ? i != 1 ? i != 2 ? "" : "MPG" : "L/100" : "KM/L";
}

protected String GetRangeDW(int i) {
return 2 == i ? "MI" : "KM";
}

protected String GetSpeedDW(int i) {
return 2 == i ? "MPH" : "KM/H";
}
[Android Head-Units] niconoel:
Here is what I have when I go to this on-board computer part.

it's true that when I enter a 4-digit code, example 1111, it displays 3000 in the area where there is the flag. if I enter 1234 it displays 1234. the seller told me to set the canbus to 11 and it's psa because I have a 2017 Peugeot Partner car. but he also told me 58 psa foreingn. and that 58 I have not tried yet because everything worked with the 11 except this computer problem. in the list of 11 and 58 I cannot find Peugeot Partner. maybe that's the problem.
[Android Head-Units] niconoel:
for me it takes L/100 and km/h

Is it possible to modify in the file so that everything is correct? I am very new to this.
[Android Head-Units] TorstenH:
And what do you want to see instead?

Or is the head unit itself showing different values?

Sorry but I can't compare the values because the dialog covers the numbers on your picture of the head unit screen.
[Android Head-Units] niconoel:
that is not good because it must be L/100 and the value 11.6 is not good because my car computer says 8.4 L/100.
[Android Head-Units] TorstenH:
Both values are correct:

1 / 11.9 * 100 = 8.4
[Android Head-Units] niconoel:
then it is the km/L data which calculates incorrectly. if we modify in L/100 it will perhaps display as on the original on-board computer.
[Android Head-Units] TorstenH:
Don't think it's bad to know that you need 8.5l for 100km what means that you can drive 11.9 km with one liter.

To be honest I don't see an issue here.
[Android Head-Units] niconoel:
here in Belgium we are used to consumption in l/100 and not how many liters per 1km. it's not easy.

there is also data 1 and 2 which are shifted on the on-board computer. here on the photos, the 1 on the original computer is the 2 on the car radio.

Hello everyone !

I have issues with my junsun (6go+128gb). I want to factory reset all the configuration to get back as the first turn on. I tried multiple things:

- in the factory mode (8878) erase all content. But the configuration stay like the bluetooth name i gave it.

- I tried to press the rst button, it's restart but cannot boot in the dfu mode. It's just restart the androidunit.

I think i need to factory reset because my wireless carplay with carletter not connect. The bluetooth is connected /the carletter app start but nothing happen. It as already work and i have in my iphone the name of the carplay detected but not connect and impossible to connect to it. I wait like 5min nothing happen.

I reset my iphone connectivity settings nothing change.

Second problem i have parking sensor and camera with my car. The camera works but not the parking sensor. I don't know how to connect it. Is it the pink parking cable i need to wired with the red cable next to camera cable ?

I hope you can help me.

Best regards

Hello guys,

I'm new on this forum and would be very happy if you can help me.

I have purchased junsun android radio 64+4 for Honda Accord 2007 (EU) and would like to connect external microphone with the radio. I pluged the microphone in MIC connector behind the unit but it still uses internal microphone that is terrible quality. Is there any setting inside the radio that let's me switch internal with external microphone? I looked everywhere and did not find it.

Thank you for you'r future help,

Download the zip file. Extract it and put the bin and the upd file on an old USB stick. The head unit should recognize the update files by itself and ask if you want to update.

No glue.

Hello,

I have a Junsun V1 Pro (128 GB/ 6GB).

I accidentally changed something in the Settings (8878).

The side control buttons do not work and my radio does not work either (cannot listen to the radio).

I would like to reset all the settings as they were originally. Unfortunately, I have played around with it too much...

A reset didn't help either.

I would be very happy if someone could send me screenshots of what the normal values are?

[Android Head-Units] thomaass:
Hello,

the side buttons may do not work because you maybe reassigned them. What I mean is that the button are not assigned for each function. Try to configure the side buttons in the menu "Touch study" by clicking the function for example "Vol -" and the side button. The button will turn dark blue on the display which means it's been assigned.

I'll send a screenshot of my radio configuration which works (at least) in my car with a V1 Plus.

My switch buttons only light up when I switch on my car lights... is it possible to activate this permanently?

It would be very nice if you could send a picture of your settings from the "Others" section.

I think something went wrong there too.

By the way my Carplay doesn't work so well, is it possible to update the Carletter app or the system in general?
[Android Head-Units] thomaass:
Hey,

I'll attach my other settings which I modified a little bit. Still, it works.

I've already tried to activate the side buttons light but I couldn't find out how, too.

The Carletter app should be set in the section "other" > "AutoLink" (you can see it on the pictures). I guess if it still doesn't working you need to contact the seller for the latest firmware or find new firmware/new carletter apk in the forums. But if carletter worked before you change the factory settings, it is probably the cause. (or try to clear the cache)
