So I've just paid to have the reverse camera that came with my unit installed, which I should have been able to do myself, and neither of us could get the image to show. Just a blank screen with the reverse guidelines. YouTube videos etc seem to indicate that it's just a case of switching the rear camera type to AHD_720 and do a reboot, but that's made no difference.

And What's the precamera input type setting all about

Anybody got any suggestions please?

Does this model have developer mode/options and if so how do you enter/activate them as I've tried the standard way.

Hi,
After struggling hard to find how to update my unit (what doesn't seems possible with USB key in my case ; only with a MicroSD card), I finaly did it.
This new system is Android 11 based, and allow to connect to Android Auto wireless, sounds good uh?

My unit is AC8257 based, and has 8 core, 64 GB ROM, 4 GB LPDDR4 RAM @ 1024x600, but the upload also contains 800x600 & 1280x720px, there is .BAT files that make easyier to pick up the good Android_scatter file.

Here is where I come from first :

And here is where I am now :

Below, a picture of the app/system that detect that my phone is close by and ready to pair with Android Auto. I first had to connect it with wire to show him the way. It now seems automatic.

Hi Most of the reverse cameras that come with the head unit for free are NTSC output type. So when you go to settings then select camera hardware channel or similar option to NTSC or in some units its CVBS kind of. Try it good luck

Hello guys I reverted back to the firmware for which I posted the link before. Fastboot working perfect with google maps and other apps. Bluetootj connects very quickly. 360 camera app working good its bit different than other AVM360 but not asking for activation. For wireless android auto I purchased headunit reloaded emulator app from play store for $6.99. Set it up with wifi launcher app in my phone. Works excelently faster than Qlink app. So any one wants everything working give a try. cheers.
Hi, confusion for me. too many version publish here. I think i have same situation, 360 camera. I not really want broke my device ;) what is version you use for 360 camera and no choice to use upload with male male usb + software ? i can't upgrade with usb storage key right ? Thank you

Thanks. I believe I tried all settings, including cvbs pal and NTSC and also ahd 720 pal and NTSC.

I think I ended up receiving a CMOS camera as that seems to be what the seller was also selling separately. Luckily I eventually found a spare AHD camera and swapped it out.

Success!!!! I have fastboot and wireless android auto working 😀😀


Current firmware info is attached and used this firmware

Now I did when I first downgraded I had to format all + download in spflash to a previous firmware then I did this one and it all works now
Wait a minute.... Why on your screenshot you have version 20220613 and me 20220614 ? and you have fast boot... maybe is the cause of slow boot ?

From memory I had to use sp flash tool version 5.2152 otherwise the scatter file would give errors
ok, i have this error because bad ascii on folder name.... Need remove all bad ASCII . haha and is already posted before.. damn.



Ok i resume for other.

-Use recent SPFlash tool like 5.2152

-Remove all bad ASCII folder name. i suggested use short path like c:\ROMS\myrom\simplefoldername because you will get error on spflash tool.

-for me i use android_config_Slim xml config because i not have 1Din enclosure

-Create a full backup of your device with spflashtool, You can use youtube video i post before if you cant use "memory test" to know where partiton begin and stop. Use WwR_2.50_Eng to check partiton structure and cut your userdata. if you can read system.img ext4 partiton i this is not bad. You can keep your RAW data because im really not expert for backup data with spflash and WwR_2.50. Maybe someone can give more detail because i not have "test RAM" option when i use spflash....

-Watch out 2610pro+ and 2610pro is not the same. I think 2610pro+ have slow boot problem. Need confirm this.

-Maybe use format + download can solve slow boot problem but i think is cause by 2610pro+ version or flash method (spflash tool vs USB dongle update.

-Maybe some person will have problem with 360 camera for activate software license. Need confirm this and found solution. i think other apk can solve this problem.

-When firmware is install you need PC mouse to solve, touchscreen calibration, bouton setup, radio setting, language, etc.

thank you for you help. too bad i cant test 360 camera because i not have right now but i want buy kit in the future. Sorry for my bad english. lol. If everyting work good for me. i think i will check to extract and recompile system.img and rename \system\media\bootanimation* file because is really ugly Target brand animation ;) and add some apk in the firmware. If someone know where is UI file structure maybe i can add other with apk MOD with other color. Normaly is not really complicated edit image in apk et sign apk after. Someone have root solution too ? just more easy to do some test for MOD this firmware....

Hi Can you please let us know how to extract and recompile system img file. That will help to put 360 apk which does not ask for activation and then everything along with wireless android auto will be working. Thanks

    Hi there!
    I'm having a bit of trouble with this recently purchased new unit photo in attachment.
    When I turn on the car the hot spot turns on by itself, the radio turns on by itself.
    The touch screen sometimes freezes/it seems that the touch coordinates no longer match or the system freezes I don't know which of the two, and then resumes normal operation after many minutes.
    I can't configure the "XINBAS" can bus module because they are written in untranslated Chinese.
    It fails to connect with my fully functional blutooth ELM OBD2 module with other devices it "doesn't see it".
    I've tried to contact Bosion but I'm getting emails with automatic replies that don't address my issues.
    Is there any update I can do?
    Thanks for any response
    I have no answers for most of these questions, however.

    My unit would not connect to my ELM OBD2 at first. I had to go into android settings/bluetooth settings and change the password from 0000 to 1234. I then restarted and then i could connect to OBD2. Hope it all works out for you

    This is possible as i have not tried such an old USB! They dont even sell them anymore in my country so this is a complete joke if this is the case. I cant understand why a head-unit that runs android 10/11 would use a 1.0/1.1 USB to update? That sounds like total maddness to me, especially because the settings are factory set to 2.0 on the unit. However multi flash drives later i still have no updates unit so you could be right.
    So here's my conclusion. I had an older model with a USB port on the front of the screen and the USB cable in the back like these. When i used the front USB port, it worked and charged the phone. When i used the back port, it work and charged the phone like a USB2.0 would but the moment android auto was activated it didn't charge the phone anymore. It actually seem to very very very slowly discharge the phone.

    As these units only have the back cable USB ports, it's the same. You get fast charging on your phone if you are not using android auto, the moment you start using android auto, it won't actually charge the phone. It's as if it can't supply certain amount of volts while reading.

    So my conclusion is power. USB 2.0+ require a bit of power to operate at those speeds. However it seems USB1.1- doesn't require that much power. So when it's booting, the USB is not receiving enough power to be read.

    Using that theory, a microSD adapter that's in USB form but not USB3.0+ compatible should work because it's low power.

    This is NOT an ANSWER, this is just an attempt to find a solution by process of elimination

    Hi,I tried this app, but I still can't wirelessly connect my android phone to Android Auto. The "press to connect" button didn't work, other settings button is the instruction.The unit is Bosion BX-D05, Android 12 . Any more suggestions? Or did Isomething wrong?

    Thanks for your help.
    For some reason that app doesn't work when installed separated. For some reason it only seems to work when it's installed with a firmware update / upgrade

    HI everyone. I have one of these systems. My problem is when i insert a USB, an upgrade page automatically comes up. It recognises MCU but not the firmware. When i got to upgrade and reset, it just asks to reboot without the option for me to select img option. Am i getting something wrong or is this the USB issue people are talking about?

    I have attached images in this order. 1: Device info, 2: The automatic upgrade screen that shows up, 3: The Upgrade & Reset upgrade option that goes straight to restart.

    Please help, what am i missing here
    Hi, I had exactly the same issue (see the 1st post of this thread), USB key was recognized for MCU, not firmware update, I fixed it by installing from a Micro SD Card, what did the tricks!

    Hi,
    Did you first manage to connect your phone to Android Auto with wire ?
    I think you need to enable the link with wire, before being able to use it wireless.

    That said, let you give you my point of view on Android Auto.
    I've struggle hard to get it working wireless, and now it's set up, it's more a pain that a benefit.

    When you have such car unit, it's totaly useless to use Android Auto that is a tiny version of Android, that don't allow you to use all apps, and has many restrictions. You better install same apps on your car unit, and set up an easy internet sharing from phone to car unit wireless (Phone & car unit bluetooth autopairing, a bixby routine on Samsung can autoenable the wifi hotspot, and your car unit will then autoconnect to it).

    The only downside is the Wireless QI app that provide Android Auto keep turning on automaticly when the car unit goes in real sleep mode (after a few days), so I need to manually turn off from time to time the wifi hotspot feature of the car unit, that block the car unit from using a wifi network.
    Another thing about android auto, it seems to use bluetooth and wirelessAP at the same time

    I want to be able to use android auto wireless.
    how can I do it?
    Open Wireless Qlink app and Re-pair your phone to the head unit
    2
    Thank you very much!!

    I want to ask you one more thing.
    how do i download and install zlink?
    the system i bought has PhoneLink installed.
    you cannot install Zlink as they dont have the license for it, you can install it and pay for it if you wish but the phonelink app works well, you can force it ti work by going to settings-general-Carplay
    and if you want android auto wireless you can open wireless Qlink
