Junsun V1 Pro MTK8259 4GB + 64GB Android 10 headunit

[TorstenH]

To reboot the head unit without factory menu code 4 you can install Reboot.apk from here:

Junsun V1 - start equalizer/AUX/BT music/CarInfo... from launcher

Additionally to the attached launcher apps you can find here an additional set which e.g. allows to start radio: https://xdaforums.com/t/junsun-v1-start-equalizer-aux-bt-music-carinfo-from-launcher.4237797/post-85047137 The app equalizer.apk...

@galaxynexus789 you must enter to advanced setup (8878 code) and enable AA/Car play and phone link.

First USB is 3.0 (there you will Connect phone), second is 2.0 for USB flashdisk

In advanced setup you can change boot logo to your car brand too

So code 4 is identical to reboot.apk ?

Yes. It preforms a regular Android reboot.

Is anyone experiencing guidelines for reverse camera to be imprecise ? I had guidelines with reverse camera in my original radio and they were telling me exactly where the car was going from start..this new one i think is wrong at radius and there is no setup for that, i can just adjust size and position of lines..
any suggestions?
Btw im using original camera

Mine are stuck to extreme right (dynamic lines). I've turned off all the lines, as they are imprecise even with the factory headunit.

You know you can adjust its position left-right with 1111 code in menu during reverse ?

The lines do not respond to steering wheel input ... they are stuck to extreme right. I'll try adjusting, but I don't see how it'll help me.

#1 note that changing a 8878/8888 setting will reset radio, equalizer, navigation app, ...
#2 in the 8878 settings menu (section Others) is this mysterious memory remember/unrememer setting. Give it a try but consider #1 if you change a setting
#3 remove USB drives because they may be configured to be Androids storage for app data. And maybe the app/setting is required before the USB drive is detected during boot process.
#4 re-flash current or newer firmware
#5 install logcat reader and check for errors and fatal messages while changing a setting or directly after boot.

Hello friends, I don't understand the English language well, I'll use a translator. My problem since I bought the Junsun V1PRO is that I don't have USB, they are not detected even if I have the cables well connected, in the Others hidden menu I see this that I attached in the image, someone Would you know how to help me? I can't update the radio if I don't have a USB option. Please help

I think that you first should disable USB debugging, and in lower part of the menu you posted you should see USB1 / USB2 settings.

Ok thanks I'll do what you tell me to see what happens in the menu.

Just want to mention that USB drive should get detected automatically and you should see a notification in the status bar. Try not only one and especially older, FAT32 formatted USB sticks.

ok I'll do it, but it's very strange that in the hidden menu I don't have the USB1 USB2 option? I have seen screenshots of other Junsun V1 PRO, and it is there automatically, without doing anything, if of course a notification should appear when inserting a USB stick in fat 32 but it doesn't. I think it's a Firmware issue, my problem is that without USB, I can't change the firmware

If there are differences in settings menu:
- have you used code 8878 to enter settings menu?
- do you have a V1 Pro (4G variant) with Mtk825X CPU? Junsun sells the V1 Pro in different variants with different CPUs based on different platforms. App CPU-Z may help.

You're in the wrong thread. This is for MTK8257 aka MTK8259 aka MTK825X.

Flashing a firmware for Mtk825X may lead to a bootloop.

I'm sure you will find other threads in this thread chaos but this may be a starting point:
