After the March 4th update, every time the stereo starts with March 4th and time 5.00 am and after a while it settles down, see the video, how could I solve the problem?

[Android Head-Units] Barykelo:
Hello. I have a new problem on my S5. After uploading the new firmware (230408), my Spotify app always crashes on launch. I flashed back the older firmware (230306) but the problem still persists. Even reinstalling Spotify didn't help.
[Android Head-Units] marioti:
please report it to the vendor
[Android Head-Units] MarcelloR92:
What could it be in your opinion?
[Android Head-Units] Clyde72:
I have the same because my unit always starts complete. My canbus is not connected. Had/have it with every firmware version since 1910 which my unit came with. It shows the installed firmware version & time on startup and shortly after syncs with GPS time. Only takes some seconds to sync. It does not bother me at all.

Again this is normal on full boot and once again not a problem.

Was discussed in the thread weeks ago so you clearly didn't read the thread...
[Android Head-Units] MarcelloR92:
Where is it written?
[Android Head-Units] marioti:
That's not normal for my HU. I just right now turning it on, from cold start (my HU is not mounted yet in a car) and it shows present time and date since the beginning
[Android Head-Units] Clyde72:
It was signaled by @Meteordust and we discussed on it so we found out that the unit syncs with GPS time on full boot. Was in January I think...
[Android Head-Units] Clyde72:
Go over the thread an you will see we had a discussion on it. Can't tell for all HU's but I remember it was discussed since the thread started in December.

You are connected to internet by 4G/sim on start up I suppose. Then it directly syncs that way. If mounted and connected to canbus it will sync over canbus. We tested it without internet connection and without canbus and it seemed to synch over gps network as soon as it gets GPS signal.
[Android Head-Units] marioti:
you are right. I'm connected to home wifi.

sorry :)

So there is solution if you have 4G module in HU. If not, you have to use to it :)

If thinking about, on the main board there is no battery to backup a clock. i don't see there any quardz also.
[Android Head-Units] MarcelloR92:
Mi dà fastidio che non sia sincronizzato

I have the same problem as you, how do I change the host?
[Android Head-Units] ConorStanley:
Thanks, but I tried this and it didn't do anything different and only gave me the default option that is the "Android" boot logo. It never found the logo on the root directory of the USB.
[Android Head-Units] Meteordust:
Hi,

First it is normal that the HU starts up with the firmware date and time, minus 7 hours or something.

When you have no 4G network, it will look at the WIFI hotspot, if not available it will take the GPS time, that can take much longer, it depends on the GPS fix, or better the GPS signal strenght of your receiver.

What I do standard after an upgrade, don't know if all steps are neccasary but it works for me.

Car Settings/Factory, code 5544.

First tab, change the SUPL host to supl.google.com, port can be 7275 or 7276.

Third tab, information, scroll down and only select, GPS, Glonass and Galileo.

Open GPS test app, left top you see three dots, select there the first tab that comes up, satellite filter, also only select GPS, Glonnas and Gallileo.

Do cold start after that.

Thats it, don't have a clue how this factory beidou gps (factory/5544) app and GPS test app work together but you better rule out the Chinese satellites, it seems it is not accurate regarding the time sync., on my HU I had time sync that was 2 to 4 minutes out of sync when I didn't do the above steps, I'm not always connect my wifi hotspot and have no 4G network on my HU.

Additional what I found out on my HU.

After some days GPS fix is going to take longer and longer, found fix for that I think.

Car setting/System/More

It will open the "normal" Android settings, go to Apps, find GPS test app, storage and clear only the cache.

Do cold start.

After that never open that GPS test app again.

You better open the Car settings/Factory and code 5544 to see your satellites if you really need to.

For me it improved immediatly the duration to find a GPS fix that you need to show the date/time when no 4G or Wifi hotspot is available.

See you also use Agama, you can also show the amount of satellites that the receiver sees,
[Android Head-Units] MarcelloR92:
I followed your guide, without an internet connection the time automatically adjusts itself after 20 seconds. Hizpo S8
[Android Head-Units] MarcelloR92:
If I put 7 days sleep mode, does the stereo consume battery? Or is it better to turn off sleep mode and put 2 hours maximum?
[Android Head-Units] Clyde72:
Thx for filling in the blanks. I never ever thought of checking gps settings again after an upgrade. Does it reset to Chinese satellites with every upgrade?

Looks cool that Agama launcher, I also should take a closer look at it... Does Sygic support traffic information in fact?
[Android Head-Units] Clyde72:
Some reported battery drain with sleep mode. I personnally have it off to be sure. Full start goes quick enough and when navigating and taking short stops when I restart the car & Waze it always asks if I still want to continue my trip.
[Android Head-Units] marioti:
If it goes to a sleep mode correctly, the power consumption is low. see my picture.

But in practice it could be differently as you know from this thread
[Android Head-Units] Meteordust:
Yes it does when you do clean install, never did it without it to avoid any conflict.

So don't know what it does if you not clearing user data when upgrading.

Sygic shows traffic jams, trip how much delayed, better route and so on...it is accurate also..but for that of course you need 4G or wifi hotspot connected.
[Android Head-Units] marioti:
i have made 3 updates, always leave my datas. And as for now, didn't have any issue with my added aps. Your GPS mod didn't go back to factory set.
[Android Head-Units] Clyde72:
I will check GPS settings, will do the cache clean meanwhile... + connect to home wifi for some app updating...

I always keep user data, never gave conflicts (so far, touching wood 😉).

Thx, seems similar to Waze then. Needs also internet for traffic info and such (logical when wanting real time info).
[Android Head-Units] ConorStanley:
Thanks. I'll give this a try. I had it set to 1024x600 then rotated it. I think from everything I've read and the suggestions, I have a couple of things to try.
[Android Head-Units] Clyde72:
@Meteordust. GPS settings still all ok, didn't gave option to clean cache from GPS test though.

I did notice something, though the unit does not have a CMOS battery it must have some mem delay. When shutting down & restarting the car within in a short time period, time & date remain + also e.g. Waze remembers you were travelling somewhere. Noticed all of this when making fuel refill stops or quick stops at a shop...

Installed the trial for Agama. Though I neither want the Chinese to follow me I neither want the Russians to do so 😅😂. Nice to be able to put a compass on screen, to be sure to know myself which direction I am going at least 🙃.
[Android Head-Units] Jeka1400:
As far as I was able to notice, the time in the sleep settings does not match the specified one. Presumably (I didn’t measure it very precisely) hours are equal to minutes, and days are equal to hours.

I measured the current consumption before installation in the car and it did not exceed 10mA. It takes about 1 minute to reach this consumption of the radio tape recorder, and although I’m not sure that I had sleep mode turned on at that time (I had to start it later with a code in the engineering menu), but after reaching this current consumption it turned on as if from sleep (I turned it on practically immediately after reaching this consumption). Now I have a 7-day mode and the next morning there is a cold start of the radio, while there are no problems with the battery.

Hello,

i'm about to buy an S5 hizpo/ossuret unit. Are you still happy with it ? No big issues so far ? i hesitate between this one and teyes for mazda 3 2010.

Teyes says reverse sensors won't work, hizpo tells it will. Any suggestion ?
[Android Head-Units] Jeka1400:
Bought two Teyes radios for clients. The difference between them is mainly in the settings menu. In Teyes it is more user friendly, in Russia and Ukraine there is good warranty support, plus there is a rear camera view mode without reverse gear. I don’t see any other pluses, there are freezes during operation on two devices, sometimes you have to reset using the button on the screen, but Teyes’ price is almost twice as high. To itself took S7.
[Android Head-Units] Lione2:
thanks for answering.

Living in western europe so i don't need warranty they provide for those countries.

Android auto wireless works as it should ?
[Android Head-Units] Jeka1400:
What connection do you mean? Bluetooth connects quickly, Wi-Fi connects to the access point on the phone with a "push" (requires you to go into the settings), at least in a city with a bunch of access points and if you need it quickly. And I don’t use android auto because of delays in controlling through the radio screen - it feels like I’ve returned 10 years ago to the old device. I do not like communication with satellites, especially in dense urban areas and on a cold start. While looking for an alternative GPS antenna
[Android Head-Units] Clyde72:
Android Wireless should work if your phone runs on Android 12 (not a fake android 12 😉) but I don't use it. I have installed all my own favourite apps on the unit + don't care about socials and all when behind the wheel.

Happy with my S4 since months. I if should look & search well I could find issues but some people always will find issues even with the best off things.
[Android Head-Units] Jeka1400:
It all depends on what device you used before. Before this device, I had a flagship phone with an OLED screen as a multimedia station. For him, the case was printed on a 3D printer, so it looked like it was in the factory version. So the screen, the operation of the sensor and communication with satellites were at the highest level, and now I don’t have enough of this. I made a replacement only because of the screen size, I wanted a larger size. At the same time, I had full control from the joystick from the Sony radio and turned on the view from the rear camera when reverse gear was turned on. The only thing that annoyed me was the turn-on delay of ~6 seconds.
[Android Head-Units] Lione2:
Thanks for answering!

I saw there is a website with all information and firmware updates ( autofather.com ) it seems to be encouraging for the future. Did you update your unit ?
[Android Head-Units] Jeka1400:
Yes, updated. The seller immediately sent me an update from 03/04/23

I remembered that the surround sound setting works better on Teyes, on my S7 the difference from the position of the controls tends to zero. Reassures that this is not a very important setting.
[Android Head-Units] Meteordust:
What you mean with "didn't gave option to clear cache"....when cache is empty it is greyed out (like you never opened the app)...or don't you have the possibillity at all?, no storage/ clear data or clear cache.

How fast is your GPS fix, assume you not having the stock GPS receiver when it shows 20 satellites like me, if it is no longer then 30 seconds I think you don't have problem like I did, my unit went from 10 seconds fix after boot up to mainscreen to over a minute in one to two weeks, clear the cache made it to 10 to 20 seconds again for my unit.

Like I said before don't have a clue what this GPS test app is doing or interferes after you open it ones in relation to the gps software that seems to be the GPS Beidou system app, probably the factory/ 5544 screen.

I can say that when my HU fan stops, around maybe 30 seconds after taking key out of ignition slot, then start unit again my date/time is always on firmware date/time....maybe car/ canbus related??, knowing you don't have canbus fitted, probably my HU gets totally without any 12 volt in 30 seconds or a minut after taking my car key out.

BTW I'm on Januari FW and MCU, when something runs nice without issues, no need to upgrade.

Tested the others but from 0207 something went wrong with the sound, but maybe it is only me ;)

That's the reason I did factory resets, clear user data, because of the downgrades mostly....otherwise it will leave traces of updated or new apps.

Upgrades probably will do fine...like you and @Aaantonn mentioned, I like fresh and crispy :D
[Android Head-Units] Elrathias:
Yes very happy. If you have BOSE stereo, you need to connect low level outputs to stock harness cable, instead of using normal cable, else its insanely loud.
[Android Head-Units] Lione2:
I have the 6 speakers model, but not bose. Do you have this car ? Reverse parking works ?
[Android Head-Units] Clyde72:
I have the stock gps receiver and the antenna that was delivered with it. Antenna is placed way up in the dash in the center. Only some plastic separating it from the front window. GPS fix is 14 seconds or so since the mod. Before it was way longer.

I could clear data & cache but cache shows 0b. Not much to clear here.

Could be car related. Still not reconnected canbus...

0603 fw & 0207 mcu here, still waiting for a monthly, the Chinamen skipped a March monthly it seems...

I can be wrong but seems like S5-S8 have more often issues after updating...
[Android Head-Units] Meteordust:
I got simular results, but with sharkfin antenna, my car gives inside problems with stock receiver, never went to 40% signal strength, maybe 12 satellites visable, placed it everywhere to test.

Now I have above 40 to 60 % strength, highest visable satellites I had was 27...but mostly it moves between 17 and 23, shown in Agama.

My cache was not empty, when gps started to take longer, now it is and also greyed out, nothing to clear and quick gps fix like you.
[Android Head-Units] simetra1:
Hello friends. When my car is idling, the sound is very good, but when it moves, the sound decreases. What could be a problem.
[Android Head-Units] Clyde72:
I wanted something built in, designed for a car like a head unit 🤔 running on Android without overspending. Otherwise I could have hammered a tablet in it or maybe a 4k smart tv 🫣

We should consider an award for most original comparaison. But the I7 laptop is still on first place 😅

Okay, for some reason, mine did not like three different USB drives I tried. I had to use an NVMe drive that I have that's super fast. Mine won't read the regular USB drives well at all. It will detect them, then they are gone. For me, it won't matter because I'll keep the 1TB NVMe drive on it and use that for updates, etc. But I'm sure someone else will run into this eventually.

[Android Head-Units] Renatovi:
Hi everyone

i have this s3 device

I would like to know with which app can I adjust the speed of the cooling fan?

Thank you
[Android Head-Units] marioti:
There's no such thing. As far as we know, a head units produced to December 2022 got only possibility to turn on or off the fan. Since then, the stock fan app. can also turn on the fan if the cpu temp reaise behind 50 celcius. So without mods (eg. Aantonn mods) you can't do anything more with fan.
[Android Head-Units] Renatovi:
thanks for the answer.

where does the fan turn off?

from which menu?

Thank you
[Android Head-Units] marioti:
you should have the fan app. Se the picture
[Android Head-Units] Renatovi:
There is no fancontrol app in my car stereo

I want to install it but which one exactly?

in the play store?
[Android Head-Units] marioti:
It is stock app, you can't find it in play store.

Do you have the newest software https://xdaforums.com/t/firmware-qf...-uis-7862a-7862s-not-fyt-based.4541261/page-9
[Android Head-Units] Meteordust:
If you not see the fan app in stock launcher app menu, it probably means you have a mainboard produced before December 2022, like almost all of us and fan app is hidden, maybe it is visible in latest firmware I'm not running, but still not working when you have not the newest mainboard, produced after 22 December 2022.

This means no fan control, always on, is better in my point of view because the amplifier/ power plug area becomes warm, so fan will give some cooling for that also, pushing the warm air away from cpu and cool the mainboard, but maybe others think differently.

Only the stock fan is not that high quality and needs to bear the 14 volt when engine is running, search the thread for solutions for that.
[Android Head-Units] kabelgleichung:
I got my Erisin labeled UIS 7862S head unit today. As the unit has a build in CAN bus decoder, I don't know how to power it on on my desk using a normal power supply unit. On my old head unit, there was a pin for ignition. How do I power the new unit up on a PSU? The usual tutorials I found always refer to the ignition pin which my HU does not have.
[Android Head-Units] marioti:
Don't you get the user manual with pinout? I need more info. What do you have on the backside of unit? I guess, you have the power socket not like ours unit, but a quadlock? what car and model year?
[Android Head-Units] kabelgleichung:
Unfortunately there is no pinout in the "manual" (manual are just a few pages). The backside looks like this: https://ae01.alicdn.com/kf/S333f1f5...GPS-Drahtlose-CarPlay-Auto-Stereo-SWC-F-r.jpg

(Quadlock connector is the black socket on the left). It is for a VW Golf 6, 2011. The unit is a Erisin ES8528V-CG.

don't plug canbus unit and power both acc and B+. it'll start up. if you connect canbus it won't.
[Android Head-Units] esmeraldo18:
my unit has canbus decoder and it gets reverse gear data from canbus. so I plugged my reverse camera to the unit and I used the + cable coming from canbus to power reverse camera but it has noisy picture, even worse if something is playing and the volume is high. do you know how to solve this?
[Android Head-Units] marioti:
You need stable +12V with separate wiring. In my case, I get it from fuse box and puted a wire all to te back
[Android Head-Units] nyp42:
To work best as an antenna those wire need to be straight. It's a long shot but maybe the wires are folded or coiled up. Also they need to be a certain length. Is it possible one or both (I think one is wifi and the other bluetooth) have been cut or broken?
[Android Head-Units] nyp42:
This is a real longshot but is probably worth a try.

The unit in this video looks exactly like mine but given that the video is 2 years old it might be different. In any case according to the description this person was able to recover a non-bootable unit by putting the flash files on a USB stick and then powering the unit on and off in specific way. Maybe try grabbing the most appropriate files from this thread and following the instructions in the README.txt.
[Android Head-Units] popamor:
Hmmm, thanks, I'll try fiddling with it when I get home.

Ok, I tried opening the app, my current setting is Auto and the fan started spinning right after power is supplied. The unit temp is 27C so I am thinking that it should not be running at all yet or maybe it should be at a slow speed. Mine whines like it is at top speed all the time even if my unit temp is at 30C when I turned the unit off.

Are you using a different app that has settings for fan speeds at set temp levels?
[Android Head-Units] popamor:
Straight as in perpendicular from the flat back of the unit or straight flat against the flat back? I have it straight flat on the back of the unit. Maybe I should try it sticking up/out front the back
[Android Head-Units] popamor:
My experience is after I loaded the newer firmware, the Wi-Fi reception became not as good. Similar to your issue of not being able to hold on to the connection. I had to run an AP in my garage to get the connection to stabilize.
[Android Head-Units] nyp42:
I ran mine perpendicular to the unit and also put some heat shrink on them to stiffen them up a bit. Linear antennas receive signal along their length and the two tips of the wire are dead spots. It seems to me that laying the wire flat on the unit likely shields nearly half of the antenna. I don't know if it makes much of a difference but that made sense to me.

I think I have also seen a few posts saying the wifi worked fine then when the firmware/MCU is flashed wifi sucked though.
[Android Head-Units] Clyde72:
As to one thing that I have noticed is that the unit's wifi doesn't seem to like 5 Ghz band. At least not over hotspot. I use hotspot when on the road and my phone is capable of creating as well 5 Ghz as 2,4 Ghz hotspot. Initially the unit found but didn't want to connect to the hotspot, when I prioritised the hotspot to 2,4 Ghz band it connected flawlessly and ever since I have stable connection over hotspot. Even while the port with bluetooth/wifi antenna isn't connected since more then a week.
[Android Head-Units] nyp42:
Awesome that worked. Thanks. Not being able to factory reset is a serious issue in the long term.
