hey guys anyone found a way to select which apps to send to the second RCA connectors ? I want to be able to display a video or something like that on the second RCA screen while my main unit display the launcher or google auto (I don't want to get fined for watching a kid show while driving lol)
[Android Head-Units] fani:
Is that illegal?? lol, I always have some videos playing on mine while driving.:eek:
[Android Head-Units] koontzy65:
Actually here (Quebec, Canada) yes it is, you can't even program a GPS while driving. Just the fact I have a custom screen in my car can get me a fine since I'll have to prove I wasn't watching something on it while driving lol
[Android Head-Units] adamhumphrey:
Is my unit similar to these units
[Android Head-Units] koontzy65:
Nope not at all ;)
[Android Head-Units] adamhumphrey:
Any ideas where I would find a firmware update for it?? I would like to use a newer android version if I can.
[Android Head-Units] koontzy65:
If there is nothing on xda, your best bet is to ask the seller of the unit. Else, lot of time there is simply no upgrade at all
[Android Head-Units] Maxkir:
To increase the speed of wifi, on some firmware disabling the bluetooth in the curtain helps.

It also helps to install a wifi antenna, instead of wiring in the connector. http://4pda.ru/forum/index.php?showtopic=936535&view=findpost&p=87039361
[Android Head-Units] fani:
I have done similar upgrades for wifi and cooling on mine. :good::good: wifi reception improved, ie. it would get 3 bars instead of 2 for instance, but the download speed remains the same. Disabling Bluetooth helped.

Sound and microphone already work satisfactory so I didn't bother changing.
[Android Head-Units] PamelaGirl:
Thank you both for the reply pertaining to Wifi.

At last my unit is in the car and I dont want to test fate by reopening it to add on a wifi wire. I will try turning off bluetooth first.

Thank you :)

How to permanently change region/ time zone? Every time when I start radio and synchronize time by GPS I have GTM +3 zone (moscow time) but i am in GTM+2 zone so I have manually change my time from e.g. 7:00 to 6:00 (or manually change time zone).

Fake AF, it's marshmallow. I asked him already but he won't send them. Can I dump it myself?

[Android Head-Units] PamelaGirl:
What maps are you Good People using?

I was using TomTom Go but now I am liking the many different screen options in Sygic.

Thanks
[Android Head-Units] fani:
Sygic for the most times. it works well with agama's center widget.

& Offlinemaps and igo nexgen as backup, because sometimes Sygic asks me connect to internet and not work without.
[Android Head-Units] PamelaGirl:
Auhh very nice viktorsaari.

May I ask what version of igo are you using?

Our setup is very similar with being rooted and running Agama Launcher.

I just want the quickest starting maps with quick access to my music. My music app is n7player Music Player, I spent a lot of time looking for a player that focused on album art. I wanted something with that old school carousel horizontal scroll, so n7player Music Player fits the bill until something else appears.

Thanks :)

Thanks :)
[Android Head-Units] darkado:
How did you root your HU? It kinda looks the same as mine.
[Android Head-Units] fani:
We installed pre-rooted firmware, Link is in the 1st post,

But I recommend making a full backup/memory-dump of your working device before trying anything new, in case you need to revert back.
[Android Head-Units] PamelaGirl:
Yes follow the instructions from the first post.

Viktorsaari is the man with the plan, he helped me every step of the way, without his help my head unit would still unrooted and or bricked.

Do that backup of your firmware before doing anything.

:)
[Android Head-Units] math_green20:

[Android Head-Units] thomasraz:
My new (received Aug 2019) unit was shipped with Android firmware "YT9217B_00002_V004_20190530" and MCU firmware "HW8227L-3.3-SW0-3.1"

When I boot it with the test points shorted, it does NOT automatically look for updates on the attached USB disk. Instead it presents a boot menu (like a lot of Android cell phones do) with the following options:

- Recovery

- Fastboot

- Normal

As long as the test points are shorted (Vol+ pressed) the menu selection cycles between those 3 options. Using the test points as a momentary switch input, I can select "Fastboot" (as I assume I need) but the "Vol-" must be pressed to commit the selection.

I have not yet found a direct "Vol-" input to the CPU. I have found two other sets of pads on the PCB that operate Vol+ and Vol- as from the virtual/touch inputs, but those only work after Android is booted (do NOT function during boot).

Are you aware of a hard Vol- input on the PCB? Or another method to select Fastboot?

*To be clear why I ask: I'm probing for interesting IO ports, in this case to add another/new method for updates via Fastboot on newer firmware. I do not need help with Flashing updates (yet ;)
[Android Head-Units] t3l3m4k0:
When you are into boot menu have you tried to validate optin with a usb mouse, maybe it works :confused:
[Android Head-Units] thomasraz:
That was an excellent suggestion. But no. The USB mouse does light up during the initial boot, but it is dead at the "Select Boot Mode:" prompt. I just tried it on both USB ports. Moving the mouse, left click, right click, scroll button, scroll wheel all do nothing.

Thanks for the suggestion, though!
[Android Head-Units] fani:
One of the two large dots (test points) is ground, one is vol-up, and one of the smaller points in circles is vol-down/ok. They work by shorting to ground. You need to experiment and find which is which. I forgot.

[Android Head-Units] PamelaGirl:
Hello Good People,

viktorsaari, you a mentioned multi windows setup, and I was interested in knowing how you did this?

I would like to always have my Map app and music player app displayed on the screen together. Is there an app that can resize an app window? Sometimes I would quickly want the map to be cover 70% of the screen, while other times I want the music player to cover 70% of the screen.

I would consider such a setup if it meant putting AGAMA Launcher on ice.

Super Thanks :)
[Android Head-Units] PamelaGirl:
Just tried this on my phone running Marshmallow 6.0.1 so will try on the head unit tomorrow. If anyone is interested here are the steps:

•	Install a file manager app with root access.

•	Open the newly installed file manager app and grant it root permission.

•	Go to*/system/*directory and open*build.prop*file.

•	Inside the file, change the value of build type*from*user*to*userdebug.

•	Save the build.prop*file.*

•	Reboot your device.

•	Once back, enable Developer Options:*go to*Settings*>*About Phone*> tap on*Build Number*seven times.

•	Go back to*Settings*>*Developer Options*> go to the bottom of the Drawing*category and*enable*Multi-window*from the options.

Yep, it was that easy to get multi-window on Android 6 on your rooted Android smartphones. For the tablets, all you need to do is enable developer options, and then toggle multi-window on. Enjoy using multiple apps in the split view mode.
[Android Head-Units] fani:
I tried the same, but got error that my build.prop file was "read only". I was unable to save the edit.
[Android Head-Units] PamelaGirl:
Stay the course my friend as it can be done. I use Root Explorer. Within Root Explorer:

1. Long press on the build.prop file.

2. From the three dot menu choose "Open in Text Editor".

3. Click yes for the pop-up window saying "A message appears saying the file is read-only. Do you want to remount as read-write and continue the operation?"

4. Change ro.build.type=user to ro.build.type=userdebug

5. Save it.

6. Reboot

7. Go back to*Settings*>*Developer Options*> go to the bottom of the Drawing*category and*enable*Multi-window*from the options.

8. Reboot and you should be all set!

Interestingly my build.prop file was already set to userdebug. I enabled Multi-window from the Developer Option and it worked after a reboot. Now I can achieve the multi-windows and still have AGAMA as my Launcher. :victory:

Hi

Few weeks ago I have received similar device ac8227l 2/32 version. Actually everything works good , but sometimes when hu is running Google maps music is being hanged for milliseconds . I have check system utilization and definitely it occurs when all cores rich 100%. Do you have any similar experiences?
[Android Head-Units] PamelaGirl:
I have not experienced this yet.

Having my device rooted I am able to delete apps not needed. I also use Greenify and Titanium Backup to freeze apps not being used. I also make sure extra apps are not starting up after the system boots.
[Android Head-Units] spewaq:
And what apps have you freezed/deleted? Former I have used greenify with Xposed on another device and didn't see any difference.
[Android Head-Units] PamelaGirl:
So far apps like:

Google Map

Calendar

Back Camera

I am using my unit to do two things:

Play music

Off line maps via Sygic and TomTom

System resources that aren't needed are being researched and if possible being put on ice.
[Android Head-Units] fani:
Sadly, it didn't work on mine. I see no option to open the file in text editor (i have a text editor installed). while using root explorer. and with ESfile explorer, it says file is read only.
[Android Head-Units] PamelaGirl:
This is odd, Root Explorer opened it via its built in text editor. I too would get the read only message but moving forward it says it will change the permissions to read-write.

You can copy the build.prop to your download folder and from there to your computer and find an editor to do the deed. Come on viktorsaari, a guy like you has to have multi-windows on their head unit! :cool:
[Android Head-Units] PamelaGirl:
Also this a try for split screen

hi! just got this unit yt9216c. trying to use sygic with aimp. already gone thru the steps in engineering settings to prevent music from pausing. but its not working. after sygic voice finished talking, the music will not resume. current firmware is factory original yt9216c-ahd-00005-v004-20190510-hifi. would it work if i flash the earlier version from the pd4ru website 20190426?

thank you

yantz
[Android Head-Units] fani:
I would suggest trying another navigation app. the same happens on mine using "OflineMaps". Sygic works fine but sometimes it forgets the installed maps and wants to download again. So for now I am sticking with the preinstalled iGo nextgen, (with updated maps ofcourse).
[Android Head-Units] yantz:
Hi viktor! So you're not recommending flash to older mod version? I've been using sygic for several years now on my mobile. I will try igo later. Igo don't have this issue with music pausing?

Thank you

yantz
[Android Head-Units] fani:
It is unclear what causing the music to stop. There are some mutex options in the "factory setting" "app setting", also option to select your navigation apps in there. but still, i'm not sure if it will help. Tinkering with the firmware is a whole can of worms with these devices. If you want to experiment, make a backup first. :good:

Good day all,

I recently bought a seicane headunit form AliExpress.

After installation i found that the local music player application was not working properly and it was uninstalled by mistake . Then I asked for upadted file from seicane support but after the update the headunit is not loading properly, its getting hanged on main screen and getting rebooted again and again

Hopefully someone will be able to help me here.

I tried to reset by pressing the reset button but nothing helps.

I have seen a dozen videos of installers saying to mount the GPS antenna:

1. Inside the dash

2. On the dash for clear line of sight

3. Upper part of windshield/up high

This is very conflicting. Where are you good people mounting your GPS antenna?

Thanks
[Android Head-Units] yantz:
As mentioned by viktor, you could try taking apart the apk and hack it. I went with installing other launcher. Try agama or car launcher, they are good car launchers.

I've never used tomtom but is there option to use Google tts? If there is, then try using Google tts instead of human voice. I'm using an app called "offline gps navigation" and it suits my needs although i have to use tts instead of human voice

---------- Post added at 02:54 PM ---------- Previous post was at 02:39 PM ----------

I also went thru a lot of videos. The keyword that i found common in most videos is "metal". I mounted mine on the edge of the dash where the metal frame holds the dash. It worked very well. The metal frame behind the radio got too many stuff above it that might obstruct the sky view. My car is a 2010 toyota estima

I re-installed the previous from my backup, and surprising I lost the fast boot. Now it does full 30 sec boot every time. :eek::eek:
[Android Head-Units] kadett 1:
How did you manage fast boot. My device always takes 30 sec. Is there software adjustment?
[Android Head-Units] fani:
yes, with MCU 2.8 (and later) and firmware May2019 (and later) it automatically fast boots in 1-3 sec.
[Android Head-Units] kadett 1:
Can you say something about this firmware? This is from my 10,1" device. I think it has the same Hardware but only 10,1" display. The resulotion is the same so I think firmware should work!?
[Android Head-Units] fani:
yes, your firmware is fine. it should have fast boot already. Or there might be a bug (like mine).

Check in Android settings, Accessibility, see if QuickBoot is enabled.

[Android Head-Units] fani:
it seems to be the same as one discussed here. Your firmware is newer but I found it to be same as before.

You can try the rooted twrp version shared in first post, but make a backup of yours first. Good Luck. :cowboy:
[Android Head-Units] KS810:
There are two zip files on the first post..

And

Can I use either zip file?

Thank you..!
[Android Head-Units] fani:
yes,

one is memory dump, 14GB

the other is only the firmware part about 1.5 GB
[Android Head-Units] KS810:
Well, I tried the usb flash through the settings, and the “upgrade android” was illuminated but when I went to restart it said incorrect file.

(I assume that since the firmware is older, it just plain said no..)

So I tried the XYAUTO folder technique and it just booted normally..

I will try the spflashtool tomorrow..
