Is there a new firmware update 8259P_1280x720 for the year 2024?
[Android Head-Units] limsheng:
Hi, I’m looking for solution for my screen when I found this forum. Will this update solve my screen problem?
[Android Head-Units] morgiee:
Hello, so an update on what I've done so far. I went ahead and installed the following firmware, overwriting my existing xtrons firmware and it installed perfectly and the user interface is sooo much smoother, easier to navigate and really up to date so thank you for the recommendations!

8259P_军灿UI02v1280x720-国外_v107_20230919

However there are a couple of issues since installing and i dont know how to fix them. was hoping you could help me with this?

1. Whatever settings I change, whatever radio station i present in the radio app, as soon as the system restarts or the car has powered off the stereo and the i power it back up, it wont save the settings i loose them.

The previous xtrons firmware always remembered the settings. so.... could it be the can bus type is not the correct on hence loosing the settings on power off? if so how can i find out which can bus type my car is so i can select the right one?

2. The car icon on the home screen works when i start driving, so its picking up the cars speed, however its in km but I want it in miles per hour. I cant find anywhere to change this?

3. I downloaded the following main UI file and installed it exactly as per the instructions and even tried the alternative method if it didn't work. Unfortunately i cant seem to install the main ui. Have i got the correct one for v107?

I need this one:

MainUI_825X_1.3v107​

but downloaded this one as it was the closest match in the attachments:

MainUI_825X_1.3

Other than that everything else seem good so far!

Thanks again!
[Android Head-Units] flaviopac:
I'm running this on an Audi. The headunit came with this firmware installed.
[Android Head-Units] dansblackcat:
maybe you can extract the mainUI from the xtrons firmware and install onto your system?
[Android Head-Units] dirkpassat:
Can you download it somehow?
[Android Head-Units] limsheng:
After plugged in the 2 update files and started swiping the screen up and down saw the recovery mode came out. But failed to read any update file and the android proceed to start as usual. Any help ?
[Android Head-Units] Terragama:
Can someone please share 8259P_军灿UI02v1280x720-国外_v81_20230427.zip version? The newest is bull... rear camera no signal or with late turning, headunit is slower than before. I need to do a flashback thx
[Android Head-Units] Terragama:
I flashed v90 version and now its allright, but i think its really Android 12, cause API is 31
[Android Head-Units] choldimir:
Why flash v90 if v113 is available? It makes no sense already.

It's not Android 12, that's masked, it's Android 9 or SDK 28...
[Android Head-Units] Terragama:
Because 113 got laggy in my device and caused malfunction of rear cam. 84 was the best for me but 90 is good too
[Android Head-Units] TheGrinch3:
Hello I falshed the v113 and all work fine with the exception of the rear cam which often (not always) the signal is down. But the same problem I had also with the previous version, the 107. I have one Kia Cee'd JD and I never touched the CANbus section (I have no idea about it...) leaving it on "ALL". Are you sure that with v90 or 84 the rear cam works fine? Thanks for your suggestion
[Android Head-Units] Terragama:
My rear cam worked great with 84, then i flashed 113 and cam had often not signal and start delay... Now i flashed v90 and its fine, but i made factory reset after flash so maybe thats the problem, some cache storing all info and after flash it was laggy, but now it work and i ll not flash it again
[Android Head-Units] TheGrinch3:
Thanks a lot for your feedback. I will follow your suggestion: with 113 I will make a factory reset and if nothing will improve with the rear cam, I will put again v90 hoping it will work better. Have a great weekend
[Android Head-Units] morgiee:
Good idea, but how would I do that? Thanks
[Android Head-Units] dansblackcat:
Haven't done it myself so I'm not sure. I believe I've seen people mention that there is an app that can backup and restore the MainUI. Maybe someone else can help better.

[Android Head-Units] Tomtom24:
Hey,

I suddenly started having problems with my reversing camera 2 weeks ago.

The camera has been working perfectly for months and suddenly the signal is very poor (it's not a wireless camera but is connected directly to my Junsin v1 Pro).

I have version 107 installed but even with that the camera worked but unfortunately not anymore.

Does anyone know what the problem could be?

Greetings

Tom
[Android Head-Units] gduck:
It seems, like a contact problem... Broken cable?
[Android Head-Units] Tomtom24:
The camera is no more than 3-4 months old. The problem is sometimes worse, sometimes better. It's not that the picture is always like this.

But often a green cast at the beginning. Quite strange.
[Android Head-Units] krajczar:
Hello,

I could not find an answer to this.

My head unit has a SIM card with unlimited internet. I want to set the WIFI sharing to always be active.

Can you help me with this?
[Android Head-Units] TheGrinch3:
Hello, I am having issues - but not always - with my rear camera starting with the firmware version 107 and now with v.113. With previous versions, v81 and v90, it worked fine. The user Terragama had the same issue and he flashed the system to v90 with the factory reset and he said now the camera works fine. In the next days I will try to do the same.
[Android Head-Units] TheGrinch3:
Hello Terragama, I found in one of my folders the version v81. If you need it I can share it with you. Let me know.
[Android Head-Units] choldimir:
Have you looked at the first post?...
[Android Head-Units] atmtm:
Do we have a camera tested that works well with our source?

Your firmware is BMW "specific."

8259P_BMWUIO1v1280x480-foreign_v21_20210628 X=1280Y=480

With other 8259P firmwares working on it, but the interface may be different and BMW-specific applications may be missing! But since you have VW, that probably won't be a problem... ?

PS: please, be careful! I think not all fimware supports 1280x480 resolution!

I'll look at what PrinceLc posted, I don't think it will be a problem ;)
[Android Head-Units] dirkpassat:

Hi guys ... This is my situation ... Radio stuck when loading Junsun V1 Pro. Help me log in reboot recovery
[Android Head-Units] gduck:
You can try this:

1. Download your last firmware

2. Extract the zip file contents to a USB drive. .upd and .bin

3 Use forced update (use the USB cable with 4pin head unit connector!):

when turning on the head unit (either from the car's power supply or from the RESET button)

- touch the screen with five fingers continuously

OR

- swipe your fingers on the screen maniacally

After that, head unit booted from USB and the installation starting.

Hey,

does anyone know if you can adjust the camera lines?

So when you activate them they are displayed in the centre of the screen but they should be further down so that the red lines start at the bottom.

I would like to move the lines otherwise the lines make no sense at all.

Thank you!

Hello, I have an junsun v1 pro for mitsubishi lancer (I don't know if it's relevant or not), but I am unable to update it. They provided me with this link, which is v113.

Hi!

Is the USB stick file system is FAT32?!

No other USB device connected?
[Android Head-Units] Teddy.:
Made sure to remove all other usb devices, it is fat32 checked it multiple times. I sent them (junsun) a message and they said to ship it to china or try again. Really scratching my head on this one.
[Android Head-Units] gduck:
Can you describe exactly what is happening?

1. restart HU with reset button (cold restart)

2. plug USB stick (you have only a 8259.bin and an 8259.upd file on the USB stick!)

and after?

Check your firmware version:

ONLY, If the firmware type is indeed the same (!) 8259P_军灿UI02, you can also try forced update:

1. plug USB stick to the 4 pin USB connector

2. when turning on the head unit (either from the car's power supply or from the RESET button)

- touch the screen with five fingers

OR

- swipe your fingers on the screen maniacally

After that, head unit booted from USB and the installation starting.
[Android Head-Units] Teddy.:
I just retried with a different sd card and it started updating. I'd also like to mention I created a new blank 8259.upd file. Currently updating, hoping for the best!

[Android Head-Units] Teddy.:
Sorry for posting right after my own post, could we update the CAN? I currently have no CAN features from my car, I have the simple soft can box, however I noticed that junsun asked me to select raisetech (hope Rz stands for raisetech).
[Android Head-Units] gduck:
What is your exact CANBus type? For example, I have a Simplesoft RP5-PA-104 and it is "Xp". I think you should open the "Xp" section and find the Mitsubishi ;)
[Android Head-Units] Teddy.:
Rp5-mt-101, it is under xp position 56 if I recall correctly, however functions like setting the amp are not available.
[Android Head-Units] gduck:
It's the same as mine, only it's for a different car, and ... then Xp is the right choice. Maybe that's all what knows. :(
[Android Head-Units] Teddy.:
I have noticed that it is missing a connector which supplies can info to HU. It is a 8 pin connector that is populated only with 2 wires can h and can l. Just search for vw passat and you'll see. I found the harness with 8 pin but it's close to 70 eur with the appropriate can box.
[Android Head-Units] gduck:
Yes, you need to connect with the 8 pin (only two pin used) connector to HU also. But this cable price in only 6eur ;) For example: LINK. But, please check your power cable connector, because for VW have two different version!
