Hello, I bought an S4 (4G/32go) and I have two problems the "home/backward/volume+-" buttons do not light (I checked in menu and/or change color but nothing). Another problem the bluetooth does not detect (in Torque or not) my "infocar" branded OBD2 (BT LE 4) (my Android phone see it), do you have any idea why?

SYS : QF001.20230304.12156_v3.48_02

MCU : QF03.V01.01.20230314.011021
[Android Head-Units] marioti:
Ok I'll check it with torque. bu what if I want to use other app. I test it with VagDPF and CarScanner, and bt not work properly (as I described)
[Android Head-Units] marioti:
Do you have working canbus? It detect when car light are on and turn on the button backlight

About bt, read posts above, we all have problems with bt connect to obd scanners
[Android Head-Units] MauriBixio:
I can use 3 different apps, but only suitable for BMW, to monitor various real-time engine parameters, erase errors in the ECU, etc. and they all work flawlessly.

I use OBD BT Vgate pro, but it also works with the cheaper OBD BT Vgate "simple".
[Android Head-Units] MauriBixio:
First of all update the Firmware and MCU with latest version.

For OBD BT read the posts back, I also wrote as I do....but you don't always get positive results with cheap OBD interfaces.
[Android Head-Units] Bro´:
i got same SYS and MCU on mine S8 Ossuret 8+128 as Lymhit. This is the last MCU version for QF03 at the moment as i know, and last "stable" firmware version
[Android Head-Units] Lymhit:
Thanks is good for light 👍
[Android Head-Units] Lymhit:
Is realy cheap odb ? (45€) (https://www.amazon.fr/Getue-Vehicle...qid=1685273659&sprefix=infocar,aps,116&sr=8-2)

Hey guys, i'm in between this Hizpo S4 vs Junsun V1Pro for my GOLF 6 2011 , i've read that Junsun have poor quality audio, do you recommand me Hizpo or Junsun radio ???
[Android Head-Units] xdsbx:
I installed a junsun on a friends car, it is much slower than hizpo
[Android Head-Units] Gyovany96:
Maybe this helps: https://docs.google.com/spreadsheets/d/1aU9D3FN478taZz-6gHiHTAZhHl1ivuM1eRihWaHti08/htmlview

It's from YouTube channel Saab Unleashed. The S1-S4 have the already very good UIS7862A CPU as the S5-S8 have the overclocked version of it UIS7862S wich is even better. I don't know for sure what Junsun use but I remember looking at some V1 HU, asked the seller about CPU and they told me they use MTK CPU wich it's not so good at all.

Good day to everyone. Faced with a problem.After updating the firmware, Topal AI does not turn on.Is it possible to reinstall somehow? Thank you in advance.

Please, more information:

Radio model?

Current version of Firmware and MCU?

Hello! There is a problem with the GPS! I was driving out of town and suddenly a problem arose. Shows 11 found satellites instead of 25, and in use 0. GPS does not work. Who knows what could have happened? I pretpologue that these are problems with the antenna, but I put it under the interior trim, now it's a whole problem to get it.)

But if the problem is with the antenna, why does it then see 11 satellites, and not 0 ???
[Android Head-Units] KoTiX2:
Guys another good news:

Today I've got the radio audio output from NavRadio+ working.

So the most problematic parts of the porting are solved.

Now it's just a matter of time to add the seek and autoscan functions and to fine tune everything.

I'm pretty happy for the progresses:)
[Android Head-Units] homyak567:
before the update, there was this firmware

I thought it does though I don't have parking sensors on my Golf MK V 2008. Climatronic control over canbus will not work for Golf/VAG but that is no big deal as these controls are seated right underneath in the center console.

In all, works great in my Golf, I even modded the OEM mic to use with the head unit. My unit comes from Ossuret, another distributor of these units.

I read reviews for Junsun beforehand and decided to give an S4 a go, mostly based on the hardware specs. I also am not an MTK fan.
[Android Head-Units] MauriBixio:
I haven't upgraded to 0508 yet, I stayed at 0414...MCU is ok.

Did you also "erase all user data" with firmware update?

When I updated to 0414 I did NOT erase all user data (I didn't want to install all my apps again) result:

Toppal AI in the end didn't work properly anymore!

I had to redo the firmware update (the same one) this time also with erase all user data, and when I'm done, Toppal works correctly.

Ok, it's a pain to install all your apps again...but that's the only way I solved with Toppal.
[Android Head-Units] homyak567:
Thanks for the advice, but I don't want to delete all the settings.Maybe there is an opportunity to simply reinstall Topal AI?
[Android Head-Units] MauriBixio:
No,Toppal it is built into the firmware.
[Android Head-Units] homyak567:
If Topal is tied to the firmware, then do I need to install my old firmware?

Or is it enough to reset the settings when updating
[Android Head-Units] MauriBixio:
I can only tell you that with firmware 0414 Toppal works for me, but only by doing as I wrote to update.

In any case, you can downgrade the firmware, if compatible with the current MCU version, only firmware is enough, vice versa, downgrade the MCU too, the version suitable for the old firmware you install.

[Android Head-Units] popamor:
My fan runs even when I have just started the unit, definitely below 50C.

@blue_one , any idea what this version update mean from post#1? Is there specific serial # date that the fan app is applicable to? Meaning that my unit has an older serial number thus not able to be controlled by the fan app?

26. Display the fan APP according to the serial number date (the boss does not display the fan APP, and the board after 2022-12-22 displays the fan APP)
[Android Head-Units] popamor:
Whew! I got the S8 version of both update.zip and mcu.bin and flashed my unit again tonight. It worked. I guess the S5-S8 needs the mcu.bin with the last 6 digits version # 002121. S4 and below uses # 011021.
[Android Head-Units] blue_one:
Hi, the automatic fan control doesn't work for me either. It has something to do with the mainboard manufacturing date I guess. Mine is from 21.06.22 so definitely before 22.12. 😣

My next exciting discovery: the head unit talks to me over a serial console. All you need is an usb to uart bridge like CP210x and connect to the shown ports. Than you can use putty (115.200bps) to connect to the console with full root rights.

[Android Head-Units] b0gdi:
Maybe somebody with a newer motherboard could take some pictures to compare them, mine is also the older one and de fan app doesn't do nothing

I will try to buy a fan and test it. The wiring i have has a fan plug on it. Maybe it works

Hello. How to add a logo, bootanimation?
[Android Head-Units] Clyde72:
Thx, I begin to see a pattern. S8 buyers seem to get better support than let's say S2/S4 buyers... but the good news seems, update files shared from S8 owners here can be used to update the lower models...

Thx for sharing!
[Android Head-Units] Clyde72:
Damn, I don't find my way on that Chinese site to get to actual downloading. Could you re upload them to Mega nz and share maybe?
[Android Head-Units] isash:
Today I received the same firmware (but for S5). Installed. All right. Only the fan runs constantly. The application does not affect it.

I also recently bought an android HU through hizpo, S8 8gb/128gb specifically for ford f150 and am having more or less the same problem with this as someone else on this forum

Only I could turn off the HU when shutting down. Everything seemed to work but no sound and no canbus functions.

I have found that there are several obd2 error codes and this is presumably the reason why the OEM SONY AMPLIFIER will not turn on.

I also think that this is the reason that the battery is drained because the car no longer goes into sleep mode but continues to search for the missing modules.

Can you give a copy of the MCU QF03 ?
[Android Head-Units] Elrathias:

[Android Head-Units] Elrathias:
I am very sorry, but i have never seen those cables on any of the k706 harnesses, can you show exactly the kit you ordered, or link to listing at the very least?
[Android Head-Units] Elrathias:
Two small blue wires are the manufacturers extremely cheap solution to 2.4ghz antennas for bluetooth and wifi.

If your car does not have a camera as standard, then yes you need to tap into the wiring harness for the reverse light, and figure out a way to snatch +12v and good ground. Its usually easy enough to piggyback the rest of the harness.
[Android Head-Units] Elrathias:
This is not possible, the device is a highly customized android tablet with absolutely non-standard hardware attatched, so they wipe everything to make sure all configuration files stay compatible with all the fixes and workarounds they use.

Edit: that is system settings and system data, user data can sometimes be saved.
[Android Head-Units] Aaantonn:
Yes, just when you turn on the download, when you have this picture, uncheck the second checkbox - clear user data. All settings and applications will be saved.

Just a question:

with custom animated bootlogo, when Android finishes showing it, will continue to display (for a few seconds) the default screen with a small progress bar and the writing "Android is starting" before the home screen or does that disappear too?

I wish to make it disappear, if possible...no "tricks" for this?

I join the request. It would be nice to get rid of this. In my case is more funny because it says (in translation) "your telephone is turning on"

i've noticed that every time i pair my phone with hu by bluetooth, it (the phone :) automatically want to turn on Android Auto. Phone is turning on the wifi on itself and trying to connect. and all the time i have a notification with this on phone. I searched in phone in AA option, but there's no possible to turn of the automatically connect (only option is: turn on "always", 'if it was use the last time", or by ''default (car decide)"). I can turn off the notification with this but it doesn't change that the phone will keep try to connect. Any suggestions?

My AHD 1080p camera is only working when set to 720p ahd. When set to 1080p it is complete grey fuzz. Anyone else have this issue? I am using the cable that came with my camera and I cut the wire that enables ahd.

Thx
[Android Head-Units] Gyovany96:
I'm using 1080p AHD without problems. Try setting 1080p25, not 30. Idk about your camera model but mine was already AHD signal and to make it CVBS you must cut a cable.. Maybe yours is the other way
[Android Head-Units] MauriBixio:
Sure ... I was wrong, sorry, I too writes the same thing as you "Starting the phone".

It would be nice to get rid of it, so we would have a cleaner animated bootlogo.
[Android Head-Units] MauriBixio:
If it's AHD you have to make it work like this (high resolution).

If you cut the wire it becomes CVBS, low resolution (at least with most cams that have this capability).

So, if the seller sold it as AHD1080 but with HU it only works with AHD 720, it's possible that the seller sold you an AHD 720 cam instead of AHD 1080... contact him and ask for explanations, or request a refund or replacement .

edit:

The video cable that comes with these cams is really rubbish, it's not shielded and it catches spurious...

I've just installed S2 in my car, first attempt no sound, contact seller, I needed to connect to the blue wire marked "AMP con" to positive (red wire), then I got sound, VERY loud, volume level 1 could barely hear music from player, volume level 2, my daugther needed to cover her ears very loud.

I'm in the program itself on the radio tape recorder, turned off the search and connection, changed my phone from android to iPhone and it can't turn on, and deleted it from the phone. A simple automatic connection of the phone via bluetooth is enough for me to make calls, without third-party programs.
[Android Head-Units] blue_one:
Sounds like you have some kind of oem amplifier in your car. What car is it? Maybe you can use a high/low level adapter to adjust the correct level for your oem amplifier.

My car is a Mazda 6 2012 modell with Bose sound system, the loud sound the seller suggested that I install the old unit, then adjust sound level, then install player again.

[Android Head-Units] Elrathias:
Usually you can choose DVR as maps alternative in launcher widget, and then in launcher settings set other navigation software as "DVR".

As to why blitzer, when both waze and google maps work flawlessly, thats up to you.
[Android Head-Units] xdsbx:
I allready tryed, on car launcher pro is only google maps and yandex api supported.
[Android Head-Units] Elrathias:
Have same amplifier, in mazda6 2013.

There is nothing you can do, the stock amplifier needs differential signaling, and only speaker level output (harness) on head unit will send that, the rca leads are ground referenced.

To clarify: bose amplifier wants an equal positive voltage and negative voltage, for each signal. It then compares the signals and subtracts out all noise to give amplifier perfect base signal to amplify.

If one of these signals would be ground, signal compared would be somewhere inbetween insanely quiet and discarded. Ie the comparator gets +5v and 0v, instead of +5v and -5v.

What CAN be done, is lower app output volume on android, voice control BOOP will still almost break your speakers, so disable that.
[Android Head-Units] Elrathias:
Disable the background service in carletter settings
[Android Head-Units] Elrathias:
Then i suppose you will have to email car launcher pro developer, and ask. Im refering to the stock launchers that are bundled in firmware.
[Android Head-Units] shinji82:
Ist there a chance in the stock ui to change the media player widget to another Media Player Widget (i use aimp)?
[Android Head-Units] x0101222:
Hi.

I believe that it disappears also and will display your animated bootlogo during the cold boot.

Keep present that sometimes when we make the update of the software the bootlogo will go to the Android default one.

Also make your animation with a indefinite time loop to be able to provide some animation during a long boot, to avoid the feeling of a stuck software.
[Android Head-Units] Aaantonn:
If you connected to the phone once, then nothing helps, everything turns on automatically every time. It only helped to deceive the program by changing the android to the iPhone in the settings.
[Android Head-Units] MauriBixio:
Maybe... with Car Launcher Pro, if you create a shortcut to your favorite navigation app in home, you could run it from there later?

I just looked at this Luncher app,it looks good...but test only on phone not in HU,but with shortcut i can run es. my favorite Navi app "Igo Israel" BUT only in fullscreen not enbedded.

edit:

we have a thread for Car Launcher Pro app too:

https://xdaforums.com/t/car-launcher-pro.3295086/
[Android Head-Units] Jeka1400:
Unfortunately no. There is one bug in the regular launcher that allows you to do this until the radio is turned on completely again (not from the "sleep" mode). To do this, you need to launch YouTube and return to the home screen, while YouTube will be displayed on the widget instead of the regular player. Now launch any player you need and it will be on the widget. This is how it works for me with PowerAMP.
[Android Head-Units] Elrathias:
Must be a persistence bug. Disable bluetooth on phone, start carletter and let it smash its viriual head into the wall looking for your phone, then hit settings and disable start automatically - background service setting, then exit and reboot the unit.

Now, the unit should no longer report to your phone as being android auto compatible.
[Android Head-Units] Elrathias:
Yes, but if you look at the rca lead it is single pin connected, ie referenced through car chassi ground - the shield on the rca isnt connected at all. Its litterally just a dead rca connected to the socket pin Fr+/Fl+
[Android Head-Units] Elrathias:
Interesting question, i do however not think so.

If you change to a different launcher, you should be able to redesign the widget layout any way you want to, but that is not a painless process due to the high amount of customization in these units.

Iirc one of the black layouts has several more options for widgets, but i dont know if third (fourth?) party apps are supported there.

Else, just use an android auto compatible media player, like spotify or Poweramp. https://www.androidauthority.com/best-music-players-android-auto-944720/
[Android Head-Units] Elrathias:
I sat down and started thinking, there is nothing that says you cant convert the cheap ground referenced signal from the hu into a differential signal yourself, but it requires a bit of electronics know how that i suspect most people in this forum does not have.

What youd need is a ±5v power output from somewhere, and 4xAD8476 single-ended to differential converters.

https://www.analog.com/en/technical-articles/adc-driving-single-ended-to-differential-conversion.html

Or somehow convince Jitu Tech into allowing a way bigger gain adjustment on the amplifier circuit, -15dB isnt enough.
[Android Head-Units] Jeka1400:
I don't understand you very well, perhaps because of the translation. I sent you a photo from an article describing similar situations in a recording studio. And if it works on professional equipment, then why won't it work for you! And in general, as far as I understand in circuitry, when connected using the RCA method, one of the inputs of the microcircuit is simply pulled up to ground (possibly through additional circuits) and it works. The difference between an XLR connection and an RCA connection is the amount of noise and the frequency range, but we are not in a recording studio))

As for connecting an external amplifier to the output intended for connecting speakers, to match the signal level by voltage, you need to set a voltage divider. I do not think that it is difficult to do and calculate in some kind of online calculator or selection method. But this method only increases the distortion and noise introduced by the radio amplifier. The only benefit in this method is the operation of all sound settings in the radio, and not just the equalizer. Although I'm not sure that he makes changes at the RCA output. There may be a clean line output.
[Android Head-Units] marioti:
Could you show me where? I don't see it direct in Carletter options, and also in this app from HU settings
