AC8257 CPU Based unit's problems & questions - Couldn't find any info about it
Thread starter
Start date
- Did not wipe out user data/installed apps installing over 5/24/22 1.73.3. Don't know about installing over older firmware (if anyone try, please report back)
- Didn't see any change although I didn't look extensively.
- DSP set to DTS with super strong bass. Setting to Rock was fine for me.

What PIP (Picture In Picture?) feature are you referring to? I only know split screen (one app on right or left half of the screen) and UI17 launcher which has a window to show any map app screen.Can PIP not run well in this version? I tried using map but it always closes and can't display PIP.
Not split screen, this is what I meant. I have T3 and can do thisWhat PIP (Picture In Picture?) feature are you referring to? I only know split screen (one app on right or left half of the screen) and UI17 launcher which has a window to show any map app screen.

This is a Andriod 8.0+ and Google Maps PIP feature. This HU's google maps has PIP allowed in permissions but doesn't show on my xyauto UI17 launcher.Not split screen, this is what I meant. I have T3 and can do this
Maybe it needs launcher supports to make it work and xyauto launcher don't have it? The video where your pic came from shows using with carwebguru on their HU.

I've tried various launchers, it doesn't work. I want to confirm if it's because of ac8275 or something else

This works on my Junsun V1 pro (MTK 8257) but only if I start a navigation (Google Maps in navigation mode).

I have a B200 ac8257 unit and pip works just fine, apart from the fact I want it anywhere except the lower right corner. You would think there would be a setting to choose which corner you have it.

Do you think it's because of the firmware? My unit seems to be using 32bit

My headunit its like this:
I think bosion AC8257 doesn't use xyauto YT5670B firmware discussed in this read. Google doesn't seem to show much info on how to get Boison AC8257 firmware.This is exactly the kind of launcher I've been looking for as Nova and FCC etc just don't suit my requirements. I have the bosion ac8257 model, but this launcher should work for me shouldn't it?
Junsun V1 Pro is different firmware than xyauto YT5670B. Probably YT5670B doesn't support map PIP you are seeking since we never seen it working. There are more details parameters in android development mode menu and engineering menu but haven't looked to see if anything can enable PIP map working.Do you think it's because of the firmware?

I think only the more recent HU models came with built-in fan. Older ones seems to have no built-in fan. Mine seller provided external fan (12v 40mm x 40mm x 10mm brushless). Yours might be smaller judging from the picture. If you want to be sure, unfortunately have to remove HU, disassemble and see.hello! I have this same radio and I have a problem, the fan makes a lot of noise, it seems that it is broken. I took it apart and put it back together to see if the noise went away but no. I need to know the measurements to buy another one and not have to disassemble the radio twice. Can someone tell me the size of the internal fan? THANKS.

FYI, 12V fan will be noisier than 5V fan (I've only connected on a electronics bench to test and haven't installed in the HU) But of course 12V power source is easy to find in the car. 5V will need to tap USB or other 5V supply inside the HU.

Has someone have battery issues? Today after not using the car for 5 days it has started very poorly.
For now I will try to change the power mode to direct shut down.

I have been reading your messages and contributions in this post and in your web page so thank you, it helped me a lot!
I would be interested on installing this launcher in my HU, I have downloaded ("gongban_YT57xx_SplitScreen-ui17-v1.73_42e18e94_ota.tar.gz") but i dont know how has to be installed because is not a "normal" apk, needs to be installed as an update or something like that?.
If I want to get back how can be uninstalled or changed?
Thanks!
I recall this launcher just overrides the default. xyauto has a lot of launchers with naming overlap (usually called "launcher1") Android's default app settings show how many launchers to choose from and which is default.
There is a "Other Settings" tab on the latest firmware's Car Settings app (don't know when introduced). This is where you set the nav app for this 3 split window UI. See attached pic
For Nav choice, I've settled on Sygic for free nav without cellular data connection on my HU. It does 2 things correctly which the other 2 free options (google maps, here we go) don't do.
- Will switch to night theme automatically. Latest google maps + HU's android version don't do this unless you are navigating a route. White background google maps is very bright for dark night use in my car.
- Sygic will automatically put map in 3D driving mode when driving. Google maps and here we go stays in 2D north up mode if not navigating a route.
But free sygic missing turn by turn and don't have google's nice search capability (require network so basically need a cell plan)Thank you very much for the detailed information! I don´t like the stock launcher so may I install that one that one because it looks much better. I supose that doing that I am not going to lose any data or app.
Sorry for my bad english but I didn´t understood your second paragraph:
"I recall this launcher just overrides the default. xyauto has a lot of launchers with naming overlap (usually called "launcher1") Android's default app settings show how many launchers to choose from and which is default."
That means that if I install this launcher I will lose the one that I have now? Or I will have both installed?
Again, thank you!
If you want to recover original UI, you can try this 4 different UI patch from xyauto for 1024x600 displays
XYAUTO (xygala.com)
Its better than reinstalling firmware if worry about losing user data and/or app licenses.Okey!
I have checked in the "Other Settings" tab of my HU and the option of "main window application" does not appear, maybe only appears when that launcher is installed? Or maybe I don´t have the lastest version? (my specs are in the post #799).
Thank you!
Comparing your System Info from post #799 to mine on latest firmware (5/24/22 1.73.3 release) on post #748. They are many differences. Don't know why. (J1.73.3 / 1.73.3, Sistema / Android os, AM+FM+RDS / NXP6856)
Can you show image of your default launcher? Maybe you have a different variation of this firmware.
