Bosion AC8257 - Android Head-Units

Hi there!
I've bought a Bosion HU (4gb ram 64 rom chipset ac8257) and works really well compared to my previous unit (PX5 2gb ram). I've registered at 4PDA forum to get some information about software but I can't find too much info about this unit..Any experience with this kind of software? I get used to the PX5 units so now I'm completty lost about this new chipset.....MCU...
Link to my product

Thanks in advance.

hey. i know its an old thread but I ve got the bosion HU.., already followed the almost dead thread at 4PDA Forum also. This head unit is crap, honestly spoken, do you have an idea if there are alterntive firmwares maybe from other manufactures that would work with the boison units? my BT calling feature stopped working after last update what has been talked about at 4PDA also. In addition I do not like much the apprearnce of the start-screen and many other minor issues too... now I am in hope that somebody has found a good working alternatively firmware file that is way better than the boison one? sorry for my bad english..

Hi! Same situation on my side.....I've tried another Android units before and this one it's not bad....I've not found another compatible firmware....If you find something please post it

I've just purchased this ac8257 b200 unit and I'm NOT loving it. My px5 with frequent wifi dropouts is preferable.
Does anyone else have an issue with the accessibility downloaded services being disabled after a short period? I've added the apps to be excluded from Battery optimisation and ensured battery saver is off and even made the apps device admins if the app can be but within an hour the services are disabled.
Also, Google voice typing seems to be like the old android 6 version with the big grey rectangle covering the lower half of the screen while listening for voice input and if it fails because the internal mic is crap I can't get it to cancel to go back to the keyboard. I usually have to exit the app and relaunch it.
UPDATE: Apparently Duraspeed is a separate task manager/battery optimisation app that comes with these units. I've now tried turning that off as well as enabling it and adding the apps as exclusions and the downloaded services are still disabled after a short period.
Google Maps also runs much slower than my previous 4Gb px5 unit.

You have probably found this post already but I got an update for my unit here. https://forum.xda-developers.com/t/...with-android-11-android-auto-wireless.4467385

8257 / AC8257 / AC8257_DEMO Android 11 & Android 12 with MCU update
So, I did some work and found Android 11 & Android 12 for the 8257 and both works, great. Along with the MCU update. The AC8257_Android_scatter.txt, found in both android files are known as project ac8257_demo, with platform MT6761. I have found...

New E-Tong unit released. Identify hardware?

A new unit was just released for the 2004-2008 Acura TSX, which is a first as removal of the stock radio removes the dual zone climate controls as well. This is an awesome surprise for the TSX community, as before we were stuck with a god awful replacement for the stock CC system if we wanted to use a double din.
Anyhow, I've reached out to E-Tong and a representative sent me some images of the About Device screen. I was hoping the community here might shed some information based on what little info I have.
This is the unit in particular:

CPU: Intel ATOM 4QuadCore, GPU4D: Mali-450 MP4

Machine Response Code

Now I'm assuming this has an Intel Sofia 3GR, particularly the Atom x3-C3200RK, as no 3G connectivity is listed for the unit outside of "support 3G dongle". I'm basing this on the Mali-450, lack of native 3G support, and 3200 in "Machine Code Response". Other than that, I'm guessing.
Assuming I'm correct, would the Sofia 3GR with 1GB RAM on 6.0 be adequate for Pandora/Spotify and Waze? I have no real other desired usage outside of that and rare bluetooth calls, with maybe the exception of playing some movie files for my kids on long road trips via a USB drive.
If so, anything to be aware of up front? I'm assuming I should be prepared to remove the unit cover and add a heatsink and fan assembly to the SoC package already. Suggested mods or tweaks?
Any and all information appreciated. I'll be relaying this information to my TSX forums as well. Thanks everyone!
Anyone have any insight?
Hey there, i just bought a radio from aliexpress for my 2003-2007 honda accord and all my info lines up with yours. I was wondering if you found out any information on it? Do you know the firmware to use to update the MCU? Thanks!
** EDIT if you care still lol
Are unit is joying software. If you look on their forum you can find a screen shot that matches ours. I ran that update and ran the root for joying devices from here and it worked great. I got viper4android installed and got some custom mods installed and it's working great.

I am thinking of buying this unit, how is it in your TSX? I currently have a non-nav TSX so I don't know if I will need to mess with the wiring harness or not.
Any help?
I have the same unit, and the clock and GPS doesn't work anymore. I wanted to reset to factory or try and upgrade it. I have it in my TSX now.
Can you advise any suggestions or recommendations?
On every start up the time goes back to 2013, 11:00pm. The only way to fix it, is go find a wifi, since GPS doesnt work.
I tried contacting XEOWYN, with no luck. I regret buying this.

Might be a long shot, but I'm having issues with my unit and would like to try and update the firmware and/or software. I'm currently on android 6.0, been seeing the newer models are on android 8.1. I tried searching through the joying forum as you suggested with no success.... Is there any possible way that you could lead me to a specific solution? Thank you for your time and good day to you.
Got the same device, but still on Android 5.
Joying firmware gets looped on MCU update, if I remove the folder with MCUs and the update binary, it stops with "OTA package and app package need to be updated at the same time"
Any advice?

Help with Identifying Chinese Android head unit

Good Afternoon ppl,
I'm looking for some help with a android double din unit I recently purchased.
Loving the features on Android in a vehicle but I have some niggling issues with it.
1) Radio RDS doesn't seem to work
2) Easyconnected doesn't seem to connect
3) A lot of normal android settings are missing
4) trying to find updates and files for apps that come pre-installed.
5) Mic isnt brilliant , not sure if theres a way of adding a new one?
this is the unit i bought.
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItemVersion&item=282795045681&view=all&tid=1800660504018
and I've got in to factory settings:
Appver: K2001_NWD_S212109.20170511.21343500.N001

I've looked around the forums and theres been some results with uninstalling updates and allowing it to reinstall the update , however Iet won't let me uninstall the updates , , I've trying installing the APK (update) and this won't let me do it that way either.
I don't even know who the manufacturer is.
Hope someone who knows a lot more about Android head units can help (Please)
Hello, I'd return that for a refund if it still in customer protection zone. I see by the link that this web is gone, probably some scam involved.

PX5 Isudar | Vehicle.apk is not working properly

Hello,
I have PX5 Isudar with latest Android 10 and latest MCU. I have installed latest Android because I was thinking it will fix my problem with the Vehicle.app
Vehicle.app is not working properly and it is working only (sometimes) when engine is not running, in some cases it is working when I make contact with key. But in most of the time i can not see doors open/closed, handbreak, seatbelt, rpm - nothing if device is running and engine is started.
I have Golf V 2006, two doors 77kw.
is there any updated vehicle. app so I can try on my Car?
Thanks
Hi, not Android auto topic, so requested mod moves. You might receive or find answers to your Android Head Unit question after identifying your head unit and asking in the appropriate forum.
Also contact your reseller for support if not already and list that, with any steps taken.
Thank you,
I can send more infos, just let me know what you need?

Chinese Head Unit - How Frustrating Can It Be

Hello All,
There is much information on this forum which has helped me so far on this android head unit journey but I am almost at the position where I might throw the damn thing out of the window and reinstall the basic manufactures head unit.
I bought the head unit from a dealer who is no longer in business and cannot contact them which closes off the normal route for enquiry.
The headhunt appears to be a generic Chinese manufacturer. The config shows as:
MCU Ver: DH200729T512188X611200805
FrameWork: 9 PQ2A.190305.002 eng.work2.20201208.100955
Android Ver: 9
App Ver: 2020120801T_1280x480_970
Tablet: rkpx6
The bluetooth function has been disabled which was originally a problem when using an iPhone as you have to hotspot every time. I overcame this with a wifi dongle and 4G card.
The GPS is terrible as well (part of the problem is the number of high rises that shadow the road). One of the main reasons for upgrading was the navigation which I generally cannot use.
So I thought a CarLinkit adapter would solve all of my problems which it did - although I get horrible screen interference that makes the unit completely unusable. The interference is completely random and CarLinkit have said that the problem is the head unit and not the adapter.
I've removed the adapter now and have to use my phone for navigation which works but doesn't solve the problem I originally tried to solve.
I seem to remember that the android version was originally ver 8 and it appears to have upgraded itself to version 9. When I play music know it takes about 2 minutes for the sound to come out of the speakers (even though the music appears to be playing). It only happens on the first boot of the head unit.
I'm currently banging my head against a wall with this technology and it appears that updating and not knowing exactly what you are doing could brick the system.
So my questions boil down to:
a) are my carlinkit issues really related to the head unit?
b) why would sound be delayed by 2 minutes after the unit has started?
c) what is the latest software I can apply to this head unit?
d) is there a better unit that I can install that will be much more reliable out of the box? there appears to be other head units available although I need a RHD option which many of the sellers on AliExpress saying isn't available.
Hopefully, I can gain some experience from others on this forum.
Thanks in advance,
DC

Any android head unit with less than 2GB RAM will be a dead zone to run apps or the OS. Apps crash a lot and OS doesn't perform well. I am not sure about your head unit's RAM capacity.
Alternatively, I would suggest uninstalling/disabling the apps that you don't really require through system settings >> apps

Android 10 SC7862 Head unit

Hi everyone,
Im new and have recently purchased a 12.1 inch head unit for my 2007 Nissan 370GT.
It has android 10 and CPU is UIS7862 3G + 32GB
I have a problem with my reverse camera and ac controls not working.
In the reverse settings it is greyed out and won't let me enable reverse cam.
Also unable to get any on the ac controls to work.
Also i have seen others with firmware upgrades that make it look a lot nicer and user friendly. Has anyone done it?
Where do people find kernels, ROMs or firmware upgrades? do people offer it as a service?
Any help would be appreciated.
┤Mod Edit├┤Facebook reference removed├ Firmware on Facebook or do google search! Best customizable firmware for these units ONLY IN FACT!​
I have contacted him, he can not do anything with the SC7862 cpu. Only Px3 and PX6
