Besides the fix I also positioned the receiver as close to the front window in the dash as possible. Also improved things. Reception is decent enough ever since. I really don't mind that much either, same goes for time sync but that chapter was nice actively experimenting, brainstorming & fun and resulted in the gps tweak by @Meteordust a.o.
[Android Head-Units] MauriBixio:
The GPS sat fix occurs already at greater than 3 Sats.

Obviously the more satellites you receive the more accurate the position.

The fix allows you to use additional satellites useful for Europe as well as the default Chinese Sats system.

So running the fix ALWAYS NEEDS to do it, in any case...

Receiving more Sats is VERY dependent on the position of the antenna.

Ideal would be outside on the roof.

Alternatively internally, above, center dashboard, without metal parts above it.

For each car the best position for the antenna must be found (if positioned internally) carry out tests to verify this position...
[Android Head-Units] marioti:
oem fin antenna. one of a better reception. Picture taken on the road trip, todday afternoon. Usually i have ca. 17 fix sattelites
[Android Head-Units] MauriBixio:
The maximum of Sats reception for the common standard GPS (NMEA Global GPS System by USA) is 12, this number of Sats have been in orbit for many years.

Then there is Galileo for Europe, with a further 32 Sats (system not yet 100% complete).

By Russia exists Glonass system.

By China exists BEIDOU system.

The Sats of these different systems can be added to the 12 of the standard "main use for car" GPS by USA.
[Android Head-Units] lontrish:
Thats odd. My system firmware says 20230712.

Just to clarify, I meant to say my system firmware was July for the S8. Not the MCU. i had an issue when I tried MCU with it saying the MCU being QF01 as to mines being QF03.
[Android Head-Units] halloj:
I think the July FW exists as it is installed by me in my unit.
[Android Head-Units] duboffik:
Hello. My s8 HU worked fine several days, but now touchscreen (not interface, just my touches) rotates 90°.

22558800 (factory reset) didn't help. Firmware upgrade (to 20230712) didn't help. And i cant upgrade MCU (because have qf03 20230315 yet). With mouse all works fine. When i rotate interface on 90-180-270 degrees with adb, interface changes, but nothing changes with my touches (they active only like on attached video - i press right corner HU, touch makes only in left side). Any ideas?
[Android Head-Units] MauriBixio:
Try touching and holding your 5 fingers on the hand for at least 5 seconds on the display, in different positions.

If doing so does not open the screen to recalibrate the touchscreen, then most likely your touchscreen panel is broken and needs to be replaced.

In this case, contact the seller to get a new panel...

Thi is tthe link of today firmware by https://autofather.com/s_sjjc

https://jitu2firmwarezlink20230614.oss-eu-central-1.aliyuncs.com/update.zip

Well,it still looks like the previous one from June, not July.

Anyone downloading from here let me know...
[Android Head-Units] halloj:
Look here and you can see both FW and MCU is the latest:https://xdaforums.com/t/general-dis...d-read-first-post-first.4525675/post-88791281. Both available in the FW thread.
[Android Head-Units] lontrish:
Yeah thats odd. I did download the initial one from Autofather and it showed up as July then I tried and redownloaded/reinstalled it again yesterday and still comes up as July from there.

Seller just sent me a firmware (also supposedly June from the url so I'll try that one to see if it turns to June or stays July).

Seeing if seller has an updated MCU or Id check the other thread for the MCU since the other halloj has QF03 but also a more updated MCU.
[Android Head-Units] halloj:
Look above yours.
[Android Head-Units] MauriBixio:
I already know everything related to new firmware, mcu, release dates, links etc. read my previous answer CAREFULLY...
[Android Head-Units] halloj:
Ok, but please why are you pointing to the old FW and not to the newest?
[Android Head-Units] lontrish:
I saw it after since we both posted around the same minute.

Thanks for the image btw, hopefully that MCU will fix my sound issue.
[Android Head-Units] MauriBixio:
Maybe you didn't read correctly:

I simply wrote above (in reply to the other user) that from autofather.com it seems that the OLD June firmware is still present in their downlaod link and NOT yet the July one.

In the FW thread I know that there is a download link for the July firmware (which I already have available) .and I will of course use that when have time to do it... ;)
[Android Head-Units] halloj:
I've been running it for a couple of days and at least on my unit the sound issue seems to have been resolved. I haven't experienced the black screen issue either.
[Android Head-Units] nyp42:
@DCB103 Thanks for posting the picture of your original firmware version.

I received the same links from Hizpo for my S2 unit as both @DCB103 and @Clyde72. I had hoped we might get the newer version from 4/01/2023 like the S8 guys got. Oh well. I have actually been runnig the 4/01/2023 update.zip with the 1216 MCU file and it seems to be fine BTW.

I tried loading the MCU that xdxbx posted on my S2 and it wouldn't load. I posted the picture of the error message several pages back.
[Android Head-Units] Clyde72:
There are lots of connectors, even within JST types. You could go to an electronics store with an harness and ask if they recognise it...

Planning on tapping into the A block 😅?
[Android Head-Units] DCB103:
for the FW in the 1228 is more information as in the 0104, can also be that S1-S4 fw was released little sooner as the other.

I also found another maybe interesting thingy on the fan, on a unit from navifly (similar specs) there was a picture where they controlled the on/off of the fan by switching the AMP in sound settings. Have not found similar setting yet on our units.
[Android Head-Units] blue_one:
It would be nice to have access to the arm debug ports when the head unit is inside the dashboard
[Android Head-Units] Clyde72:
@nyp42 found a similar setting

thx a lot for that info! my hunch could be right about controlling the fan over blue/black connector...
[Android Head-Units] nyp42:
I haven't had that issue with Android Auto but I have had it with Torque and Google Maps. I was able to fix it by switching back to the default launcher, opening the app, then using the back button to exit the app. If it launched in windowed mode this time then when you launch it again it should be back in full screen mode. Exit with back button again and switch back to your usual launcher.

It's kind of finicky to get changed but the key seems to be switching back to the default launcher.
[Android Head-Units] nyp42:
If we are able to control the fan I'm pretty sure it's just on or off and not different speeds. The help diologue (?) in the fan control app just says if turns the fan on at 50 deg C and nothing about it changing speeds.
[Android Head-Units] nyp42:
Has anyone contacted their vendor and claimed their firmware update went wrong and now their unit won't boot and ask for a way to recover it?

@Vėžys
[Android Head-Units] Clyde72:
That should allready be ok as controlling. Only let the fan turn when unit is possibly overheating until temp is safe again. If connected to 12V constant it will keep turning at all times. And apparently can kill the fan as I've read. Fans with variable speed control mostly have 3 wires, live, ground and 3rd connected to a sensor.
[Android Head-Units] Vėžys:
They don't tell me how to fix it. They said me "Return the device back and we return some of the money"
[Android Head-Units] nyp42:
That's lame. Who is the vendor?

We really need to figure this one out. Especially you.
[Android Head-Units] kikegsxr:
Hello, my seller Hizpo has sent me an update for my S4. It only updates the system and the same MCU version that it had on 12/26 is maintained. I have noticed a little better radio reception and the volume of different applications more normalized, but no It has given me more time, I just confirm that it works ok on S4. I share it in case it can help someone.

https://musetransfer.com/s/1xymy8rkv

I have finally been able to solve my 4g data problem after the suspension of the device by modifying the APN of my operator, now it works correctly
[Android Head-Units] Clyde72:
I noticed a pinhole saying "reset" on the unit. Does that do anything? Maybe pressed in while powering up or so...
[Android Head-Units] b0gdi:
anyone with similar problem? this happens when the unit starts from sleep. it's driving me nut's and the seller ossuret it's not helpful at all.
[Android Head-Units] Clyde72:
I also noticed differences in radio reception. Initial 1910 fw was good and saved programmed stations, 1126 fw was way worse reception + didn't hold/save programmed stations and with 1216 fw reception improved again + saves programmed stations
[Android Head-Units] Vėžys:
I tried to do various actions, but nothing works
[Android Head-Units] popamor:
Hahaha, sounds like Microsoft 2 groups of developers making Windows versions. Vista was terrible compared to 98, Win 5 was better, then Win8 was horrible, then 10 stinks less...

Does that point towards the 0104 version might have bad reception? I have not updated mine with this new version.
[Android Head-Units] Clyde72:
Try turning sleep mode off first, code 15935700 in factory. Take the keys off and start engine after 10 min.

I notice you have an automatic climate control, can you control it with the unit?
[Android Head-Units] Clyde72:
Why do you think I didn't try more updates yet :) ? My radio reception... 😉
[Android Head-Units] kikegsxr:
I forgot to mention that the update process changed and now the seller gave me these instructions:

Hi friends, please upgrade your radio according to this file, system upgrade: decompression copy QF folder to the root directory of the formatted U disk, the machine is fully powered on and plugged into the USB cable, the machine will automatically upgrade after detecting the U disk file, do not power off or other operations during the upgrade process, upgrade about 8 minutes, the upgrade will automatically enter the main interface. If the machine does not upgrade action, try another USB interface. Do not shut down, power off or other operations during the upgrade process.

Oryginally Unit came with

FW: QF001.20230109.190922_V3.08_01

MCU: QF01.V01.71.20230103.002121

DSP: BU32107

RADIO: TDA7708

Its S5 i guess as it has 4GB ram & 64GB FLASH memory

This HU drives me mad, loosing my patience to it as I really have no clue if I do sth wrong or its simply just faulty.

I thought I managed to sort my disapearing sound with downgrading FW from 0615 back to 0508, but it still does the same.

Symptom: on cold start when it all boots up sound plays fine for max 1-2 min then it disapears. Clearing memory and reboot fixes it again for 1 min and it disapears again, what i noticed is that when I shut down car and start it again (stand by is set to 2 hours) then i t does play fine for a lot longer , but again after 10-15 min sounds is gone again.

It really anoys me as once I think its all good and configure unit to my liking install all apps then its playing up again.

I waisted so much time on it and can not figure out what it is, tried decoding media files by soft (on/off) same for amplifier switch in factory settings but it doesnt make any difference.

I already tried FW: 0414 / 0508 / 0615 /0714

but have not downgraded MCU yet

has anyone came accros similar issue? any suggestion before I get rid of this thing?
[Android Head-Units] xdsbx:
Sounds like faulty dsp in your headunit. It will be to hot after some time and gets off
[Android Head-Units] MauriBixio:
Also possible to evaluate that those who have an oem amplification system but OUTSIDE the oem radio, when installing these HUs, may suffer from audio problems, since the amplification stage inside the HU\DSP chip is not fully compatible with that of the oem amplifier.
[Android Head-Units] lone_slayer:
Well ordered my S8 (Mazda 2 setup) from the hizpo choice store on aliexpress a month ago and they still haven't sent it. Have contacted the seller (not easy through the choice store as you talk to a bot first) and have been told it will be shipped out before the timer ends (has been extended about 10+ times). So the plan is to let the timer run out and get a refund and purchase another unit from another seller/store on aliexpress. Has anyone have store recommendations? Also are you happy with your stereo or would you buy another brand?

You are my hero! Problem with rotated touchscreen was solved!
[Android Head-Units] hojnikb:
is anyone working on custom firmware for these units? Possibly with cleaned up interface and stock apps?
[Android Head-Units] Clandaries:
I think they all get new head units QF03. Therefore they have no head units, or not enough at the moment.
[Android Head-Units] crv13:
No, reverted back MCU to version I had when I got this unit : 20230103.002121

downgraded FW to 0508 and guess what? it definitelly doesnt have same problem I was having with newest MCU

at least for now no sound cutting for 20 min.

I tried various FW with this old MCU and only 0508 is playing fine for the moment that long... will see in long run.

We have exactly the same board. Have you used a qf03 mcu on a qf01 board ? You didnt have an isues?
[Android Head-Units] halloj:
No I've not. This is what the seller delivered in form of hardware. I've only updated the FW and MCU according to the picture.
[Android Head-Units] MauriBixio:
Still...

The hardware features of EACH S8 are written identical (DSP BU32107,TDA7708 etc.) for both QF01 and QF03 mainboard.

You have to be sure instead, with respect to which mcu file to use (QF01 or QF03) if your mainboard is native QF01 or QF03, and use the suitable mcu file type...
[Android Head-Units] snaker12:
Thanks for making this clear!
[Android Head-Units] Telperion:
I'm selling my S8, if you're interest in private party (and this doesn't violate any forum rules). I got busy and never got around to installing it in my car, and now I don't feel like going through all that trouble, so it's basically brand new. You'd just need the car connection kit for your specific vehicle.
