Hi.

Anton TNT said:

Hi, in device settings / infortainment or accounts / google find option "install from unknown location" , and check that files / package (apk) is fully downloaded - maybe it is better to download them on usb and then install from usb stick thru apk installer.

(sorry I haven't learned how to include quotes yet....)

It happens to me with APKs that before I normally installed from a USB stick, but now (maybe because of an app or I don't know..)

I can no longer install even copying them to the internal memory and trying from there.

I tried to give consent to apps of unknown origin to Google

is italian: means "Less secure app access",

and now is activated.

(Is correct?)

I can't find other references to APKs in the infotainment configuration menus.

I rebooted the device and tried again to install several APKs, but the error "Error while analyzing the package" always appears!

This is my device:

I have set the language of the device in English, so as to show you the message:

A suggest?

Thank you

please use this help : https://medium.com/@GuruTechnolabs/...ing-the-package-error-in-android-c2fca91673cb

or try googling it ... I cannot help you seems to me you have outdated version of android
[Android Head-Units] marv66:
Hi.

II searched for the solution on the Internet for hours, but nothing.

Since the device does not have an option entry to enable unknown apps, I installed the "Hidden settings" app from the play store and looked for the option.

View attachment 5442085

Finally I found it, but unfortunately it is fixed on "disabled" and does not allow you to change it.

Maybe there is a block created by some previously launched app that has performed operations allowed in root,

maybe I should root the device,

maybe there is a need for some sort of reformatting that only the manufacturer can do....

Unfortunately I can not even resign myself to install only from the play store, because some applications I have only as APK (example that of my dashcam).

I find myself an unusable infotainment!

I don't know what to do anymore...
[Android Head-Units] h1p1n3:
did you try this?

click on the gear where it says HMI: and put in 8888 as the password,

go to OTHER

find INSTALL and set it to enable

find PROTECTION and set it to DISABLE
[Android Head-Units] marv66:
Hello.

Thank you for the information.

I did as you indicated, in fact the INSTALL option is disabled.

View attachment 5442569

Unfortunately when I try to activate it, it requires a password!

View attachment 5442571

Is this a known password? Does anyone know it?

Thank you
[Android Head-Units] h1p1n3:
3234 I believe. It's on the forums here somewhere. Id look but traveling at the moment. Will update if I find something different
[Android Head-Units] marv66:
Works!

THANK YOU VERY VERY VERY MUCH !!!!!

YOU SAVED ME.(y)(y)(y)(y)

I am happy to have found a forum of competent people.

Hi.

Is possible in a FF-5000 8227L system obtain an app for vocal commands offline?
[Android Head-Units] Anton TNT:
Hi, you have google voice commands just like in any android, just install search bar with microphone icon and try it
[Android Head-Units] marv66:
In my FF-5000 8227L device google voice command requires an online link.

I would need to give commands even where there is no telephone network coverage
[Android Head-Units] Anton TNT:
If your device has wifi connection just connect to internet or just make your mobile phone as main network by creating a hotspot and connect headunit thru it.
[Android Head-Units] marv66:
My ff-5000 8227L owns 16Gb ROM (... flash) and 2Gb of RAM is mounted in a Jeep.

I often travel into narrow valleys and gorges where there is no internet signal coverage. So I need an app that allows OFFLINE voice commands.
[Android Head-Units] Anton TNT:
Maybe sattelite connections ? It works with tv tuner usb card bought from ali express, In general this is not tested with headunits yet but it involves a small radio dish antenna and usb port in device (sattelite connections also uses radio frequencies similar to broadband routers/wifi), but I must say it is expensive and complicated.

Following this story you can download a program : https://www.apkmirror.com/apk/saiy-ltd/saiy-assistant/ and use this SAIY app or just use GOOGLE ASSISTANT !
[Android Head-Units] marv66:
I appreciate every idea :),

but I would avoid complicated and expensive solutions.

When I bought the car there was inserted as standard a navigator + mp3 player that accepted voice commands in different languages, all OFFLINE.

The management of the navigator maps was difficult, rudimentary and with paid updates, with a closed operating system.

I replaced it with the FF-5000 getting an Android system and the ability to load and update apps and maps at will, surf the net and more...

Unfortunately I thought I could use voice commands by simply loading an app, but it seems not so!

It seems almost impossible to me that there is no app for basic, simple,

TOTALLY OFFLINE

voice commands such as:

"Browse to location X",

"Call Mary",

or "Play the music track Y"...
[Android Head-Units] Anton TNT:
This link I gave you , not working ? have you tried any?
[Android Head-Units] marv66:
Hi,

I tried the APK of Saiy that you indicated to me in the link.

I thank you.

It's the only one that really works offline.

Unfortunately for those who are not native Speakers English is quite difficult.:unsure:

Above all it tells me that it only supports the English language, even trying to give custom commands for example de you have to give an address in the navigator that is not English does not find it... you should pronounce the name of a city or a street as if a foreigner were reading it, guessing what the spelling might be...😵😵

I tried to see on

Saiy is a Fully Customizable Voice Assistant that Works Offline [XDA Spotlight]

Saiy is an open source voice assistant that can work offline. It was originally launched in 2012 as "Utter," but now development is back in action.

www.xda-developers.com

which speaks of configurable language, but the link application says that there is only English.

Saiy is also very complex with many options that I would not use, however, if there was the Italian version, I could waste time (and I know it takes a lot...) to configure it.

If anyone knows other apps, with just the basic commands to be given (such as the examples of the last message) and multilingual I would be grateful.

For now I'll try to fiddle a bit 'among the menus of saiy, in the scraps of time...
[Android Head-Units] Anton TNT:
Must be languaege support, like microsoft has a pack to download and install. sorry to hear that all, please try then to find suitable program for you, there are many on net, just search google
[Android Head-Units] marv66:
Hi,

Unfortunately for the Italian language I found only programs that run online relying on google....

I hope that in the future "saiy" integrates the possibility of other languages besides English.

Plugins for "saiy" I can't find them.

For now with one eye I will have to look at the road and the other look where to press the touch screen...
[Android Head-Units] bhudcser:
Hi Guys,

I'm afraid the answer will be "Impossible" but let's give a try.

Is there any way to add a bluetooth device (OBD Interface) manually? I know the pairing works only in one direction (search/add the HU by the phone). In this case I would like to search for BT devices on the HU itself.

Thanks, Daniel
[Android Head-Units] MrReis:
I stumbled upon a post in another (German language) forum that adds to the information I previously posted about settings not being saved between system power cycles (China Radio does not keep the last state after switching off). The poster states "I finally found the error. In the end, the problem was that before I changed anything in the hidden menu, I saved it on my USB stick. Which in turn was plugged into the USB port of the radio the whole time. As a result, the radio apparently fetched the file from the stick for each boot. For whatever reason."

I thought that I had changed the location of the file the system used to backup settings to the same location where I created a backup. The German poster showed that actually ("for whatever reason") if a backup of the system setting is saved, then the system uses the contents of the backup file to set the system settings at power up. All settings are saved in the backup file, not just the factory settings, so whatever the radio and sound settings were when the backup was created will continue to be the settings used at system power up - until the backup file is removed or a new backup is made.

I don't get why the backup of the factory settings should be used to set the system settings at power up. I would call it a software bug not a feature.
[Android Head-Units] bhudcser:
Hi Guys, Do you think there is an option to set the subwoofer level somehow? I cannot see this in the DSP settings.
[Android Head-Units] Anton TNT:
Hi to all...

In variety of devices with chip 8227L this is common error, it happens a lot with my device ALPS FF5000, I resolved it by formatting USB /SD CARDS with FAT32 sys and this is the place where my maps are for navi software, while device turns on and off , it writes all settings instead of internal memory to SD CARD memory where maps are. When removed from slot, device settings resets it self. In factory menu, there is a option transfer settings to USB/SD CARD (just appear as icons - settings ->USB), there one must deactivate that option and reset device, and then configure all settings and turn off device.

As major interference of that error radio.app in variety of firmwares for 8227L chipsets just freezes and stops responding after first install and reboot. Fix is to install update again, go to factory menu with PIN CODE 8888 and configure RADIO menu to standard device needs and reboot. When android starts again, you can tweek radio stations, rds etc.

Chinese merchants are rather stingy about it, but they have stock android softwares with different UI settings for each aftermarket device. One must ask for right software from them (usually gives you link for firmware on cloud services) and then download. I took opportunity while downloading firmware and downloaded all softwares/apps that was there from my seller including full navi and torque apps etc.
[Android Head-Units] Anton TNT:
Yes in factory menu (access thru pin code), then section VOLUME menu, there are settings for all audio levels
[Android Head-Units] bhudcser:
That means this is only accessible in the hidden menu right? So no option to switch off or just simply lower the volume of the sub in the DSP application?
[Android Head-Units] Anton TNT:
You have values like AMP = 0 AMP=1 etc. In some settings menu like OTHER "0" is disabled, "1" means active
[Android Head-Units] snakecsabi:
Hi! Could this probably be the problem for me too? I tune in the radio stations, arrange the icons, set the default gps program to waze, and then when the unit restarts it forgets everything! I installed the system from usb and then the flash drive remained in the usb port. Would you like to save the factory settings here by default? And how can I fix this problem by basically saving everything in the memory of the headunit and not forgetting the things set up? Thanks in advance for your help!
[Android Head-Units] Anton TNT:
After update is complete before you turn off your device you must tune all settings that you want, remove any cards or usb connection from slots and then turn off. Eventually it will write to internal memory.
[Android Head-Units] snakecsabi:
thank you very much, i try and report what the result was!
[Android Head-Units] bhudcser:
Have you been able to check this? I have the same issue. DSP, Brightness and other settings are loosing right after the restart. I have only one FAT32 formatted USB stick attached to the system. @Anton TNT has mentioned to remove storage devices before setting everything up then turn off the device. This solution should force the system to save settings file to internal storage but this method doesn't work for me. Am I doing something wrong?
[Android Head-Units] Anton TNT:
Delete any folder containing ANDROID or DATA or OLD on USB that is connected on device but you must delete it on PC or laptop because headunit system will most likely lock these files if you try to delete any while connected to device port (while headunit Android system is on and actively writing memory).

Another mistake by Chinese resellers is to let system to write to other SD cards (containing navi cards) or USB ports (various softwares connected to USB like TPMS with usb support, USB DAB+ apps and amplifiers etc.).

AFTER FIRST INSTALL /UPDATE REMOVE ALL SD CARDS AND USB DRIVES FROM ANY PORTS AND THEN TWEEK SETTINGS AND THEN REBOOT DEVICE.

In some cases it takes two or more times to boot without those SD cards and USB drives in ports. When successfuly written into internal memory (you will see that icons are not rearranged again, radios work and saving stations etc.) then you can put cards or USB in ports again.
[Android Head-Units] asad5150:
I have done all that and still doesn’t save the settings. Lost of thoughts what to do
[Android Head-Units] Anton TNT:
1 solution - go to factory settings with pin code, then in menu other or somewhere there find option LAST MEMORY STATE - must be on REMEMBER or checked box, also PROTECTION option must be OFF and INSTALL option to ON (guessing all this is for ALPS device with 8227L chipset)

2 solution - on a quad lock connector find wiring diagram for your car radio on one part and head unit wires on second part and find memory wire 12V+ , usually yellow one and switch wires with red one ACC KEY ignition , crosswire it and see if helps

3 solution - if second option doesn't help , contact seller of device and he must provide you software update and if no progress still, new firmware update
[Android Head-Units] freeman94:
hello, I need help.

My alps-f5000 8227L (MERCEDES UI) bluetooth connetion just drops, and disconnect randomly but almost always. I don't know what to do, without bluetooth this radio is useless :(

It is pairing, and working sometimes so the unit is no broken, but something is interfeering with it and it just disconnect and can't connect again, I need to shut down engine and start it again so it reboot itself.

Please, any advice?
[Android Head-Units] Anton TNT:
Hello, I think that this thread is not about blue tooth and related problems but it's a problem with

device / headunit so I'll help...

First thing... Place here a images of bluetooth connection manager from device (UI of bluetooth or app) and bluetooth hardware info (in infotainment section where other infos are like HMI, MEDIA etc. - usually in a settings where you get into factory settings)
[Android Head-Units] miroslavpena:
Hi..have you manage to connect obd to hu?

In HU in Bluetooth option i see obd but after i try to connect pop up window for pairing code disappeares immediately and error msg pops up saying unable to pair wrong code..any solution?
[Android Head-Units] Anton TNT:
if you have factory settings and in it menu or option for bluetooth please set to version (BLUETOOTH) to value 4 or 5
[Android Head-Units] miroslavpena:
Which one?
[Android Head-Units] Anton TNT:
BT pair mode must be on setting 2 , BT sysnch must be on SYNC, INSTALL option to ON, AUTOLINK to ON.

And find option BTOOTH or BLUETOOTH version - it sets values from 1 up to 10. Active one is probably at value 4.

Restart...

Then try if connects and if it is stable.
[Android Head-Units] Anton TNT:
So it is ALPS AC8227L demo
[Android Head-Units] Anton TNT:
What problems do you have with bluetooth?
[Android Head-Units] freeman94:
the thing is it sometimes connect to phone bluetooth, and sometimes not, in fact even if it connect properly it sometimes disconnect and so on.

Additionally my device doesn't stick the settings i set, meaning if I set my radio stations, some Audio EQ settings etc, display brightness etc it just restore radio defaults after reboot (not always but very often)

I did look on the hidden advanced settings 8888 but i dont see any option for remebering it.

I would be so happy to solve this
[Android Head-Units] Anton TNT:
Sounds like you have cache memory, if device is rooted find folder CACHE on root folder and delete it, then restart and set everything, restart again and unit will write this changes on next bootup.
[Android Head-Units] freeman94:
Ok I'm gonna try that.

I didn't root my unit so i might not be able to access this folder to delete

Gonna look it up after work when. I get into car
[Android Head-Units] Anton TNT:
If not rooted use File Manager app from playstore or download apk and install , from inside File Managar app you can see root folder and delete cache folder (if not write protected).
[Android Head-Units] johneri:
I've had an audio problem with my head unit since I got it. The volume gets throttled after some time, it seems like it is due to overheating. It forces the volume to a low setting and keeps lowering it without ever releasing the throttle without rebooting. The temp of CPU is around 80-90c when this happens, so it's pretty obviously the reason. How could I prevent this??

Another problem is static rumbling of the audio itself. Just now I began to listen music from YT Music, and it began with mild static on each sub beat. Then suddiently the audio became clear and it stayed clear up to max volume, even with the bass. Then when I slid down the notifications slider, the static bass came back hard and didn't stop.

Does anyone have any ideas how to prevent these issues? I'm planning on opening the head unit and adding both passive and active coolers in the hardware to prevent the throttle. I would limit the CPU but I cant root the head unit because my PC doesnt recognize it, and phone cant connect via ADB either.

As for the unstable audio quality, I need some advice because I have no idea why it happens. It could be due to the car's speaker wirings because it happened with the original head unit but stopped after switching to the FF5000, though now it's random...
[Android Head-Units] Anton TNT:
Hi, I heard some rumours that a simple isolating tape between cables/input jacks (radio antenna) and casing of unit eliminates static, try that first.
[Android Head-Units] ElCons:
Hi everyone, I have a Macrom AN700DAB with android 10 and i use agama car launcher. Specs in attachment. The other day i tried to see some setting of the hidden menu (the one that is reached with 8888) because sometimes the bluetooth stops working. Basically the sound skips a couple of times and then stops until I restart the system (this problem occurs almost always if I use car launcher pro, with agama almost never). From that moment on, every time I turn the car radio off and on, the sound setup settings (equaliser, loudness, etc..) are reset. I also tried deleting the android file on the usb stick and then removing the usb stick but nothing. I also reset the system but it didn't fix it. The standby time is set to 0, although I would like to be able to set it to 60 minutes without any problems. How can I do to solve?

The last image is one setting that keep resetting (the loud go back to off)
[Android Head-Units] Anton TNT:
Report this issue to car launcher pro, they can update their car launcher software with correction.

You can try to resolve in factory settings go to OTHER section and see if you can find settings related to Bluetooth , there is a option VER or VERSION set value to 4 or 5, and just underneath is another option to activate or deactivate synchronization, BTSYNCH , set to SYNCH option. AutoLINK option must be on ENABLE also.
[Android Head-Units] ElCons:
First of all thanks for the quick reply. the bluetooth disconnection problem this morning happened a couple of times even with agama launcher. to solve I have to go to system settings, bluetooth and clear the data. obviously it is not a sustainable solution because it happens often and it is a long process to solve. I'll try to change the settings you recommended, but I'd be interested to know what they are for. BTSYNCH I've already tried setting it to sync and the only thing that changes is the volume that become managed uniquely by both the tablet and the phone, but in a uncomfortable way.
[Android Head-Units] Anton TNT:
You can try in factory settings , on menu SOUND, reduce or set higher the slider by 1 or 2 to bluetooh sounds. Maybe it will help to correct sound skipping.
[Android Head-Units] ElCons:
Maybe I explained myself wrong. The sound skips 2/3 times and then stops working until I turn the car stereo off and on again. By "stops working" I mean connected phone audio is not heard from the radio, although everything else is fine.

I would also like to know what changes if I change the bluetooth version parameter
[Android Head-Units] Anton TNT:
Nothing changes , only that uses higher version of bluetooth available.

I think that you are just expiriencing bad connectivity here or output.

On developer options in head unit, if it is visible in system, there is a test for bluetooth connectivity and debuging, but it's hard to debug if you are not a techinician, it must be done by pro.

[Android Head-Units] ElCons:
Hi again,

I'm still having problems with this unit. For example, bluetooth most of the time does not work and the symbol above flashes intermittently. Furthermore, very often the volume controls and the home button (both from the screen and from the steering wheel) do not work or they work but with a long delay, even minutes.

Basically when there are those delays the com.ts.mainu18 app is frozen and I can't open for example bluetooth or infotainment settings.

Also as seen in the attachment it says activation code does not match and it doesn't go away until I turn off the unit.

I tried to do the factory reset (erase all content) from the factory menu by logging in with 8888, but nothing changes, the problems persist and the unit is practically unusable. Also that reset doesn't completely restore the default settings. For example, the boot logo that I chose and the name of the bluetooth that I changed in the factory menu remain. I wanted to know how to do a total reset to factory settings with the hope of solving.

Thanks in advance
[Android Head-Units] Anton TNT:
Change firmware, activation code does not match is warning that this firmware updade is not for your unit. Find similar one that works and update.
[Android Head-Units] ElCons:
But I've never changed the firmware, it's the original one.

The writing activation code does not match does not always appear.

But these days the volume keys and the others on the left touch screen are practically never working. However I can try to change firmware as a solution, but the warranty is invalidated?

Where can I find a guide on how to do it and where can I download the firmware?
