Well, I can't find 1.8mm on Ali or Amaz...

Low conductivity of 2mm I find this blue type:

High conductivity this other:

I was thinking of using the high conductivity one...
[Android Head-Units] MauriBixio:
This is also a valid idea, different thicknesses superimposed... although perhaps after the thermal conductivity could be reduced by overlapping them (maybe...)

Ideal would be a single thermopad to have maximum efficiency, but 1.8mm is not found, only 1.5mm or 2mm to stay in that range.
[Android Head-Units] marioti:
The seccond one can be to hard and 2mm thick can bend the pcb a little. So maybe ask a seller how hard/soft is this thermopad are
[Android Head-Units] MauriBixio:
The 2mm high performance one should have these characteristics (grey color).
[Android Head-Units] marioti:
well this tell nothing about hardness because 30-55 Sh (Shore scale) can be soft foam or usual silicone. When i look for hardness of those 6W/mK it sais 25-30Sh. So it is as I said before, thermopad 12W/mK are pretty hard, and if in your case the gap is 1,3-1,4mm, then go in 1,5mm thermopad.
[Android Head-Units] MauriBixio:
Well, I will buy the 12W/mK thermopad, 1.5mm thick and I hope it fills the CPU\case gap adequately. ;)
[Android Head-Units] marioti:
Check the temps now and after aplication, and give us some feedback. Maybe i'll also change thermopad

Look here, they have 15w/mK, and hardness is 60-70sh So it is hard silicone.

IMO this thermalright 12w/mk, will be ca 50sh.

https://a.aliexpress.com/_EujiEJp
[Android Head-Units] MauriBixio:
Same,best price, 1,5mm , 15W/MK, B version:

https://it.aliexpress.com/item/1005005633353971.html?spm=a2g0o.cart.0.0.7c5c18fcuEBMqj&mp=1&gatewayAdapt=glo2ita

I buy this.

Without thermopad the temp. CPU runs around 47/57° max (in the height of summer), the fan cools correctly.

With thermopad I will give feedback when assemble (but long time to get it from Ali...)

Did you have connect correctly to power + cable?

Are on + cable permanent current when engine is on ?
[Android Head-Units] Baban2013:
All cables are ok
[Android Head-Units] itiswitis:
That's a problem not very common in this forum. It's unlikely you'll get an exact answer to your problem. I believe the side buttons (non physical) are capacitive buttons, there's nothing mechanical. You could try upgrade/downgrade/reflash your firmware/mcu, make sure you have the correct QF001 vs QF03. If you suspect a cable from behind touching, you could double check your connections (including internal ribbon cables) and wrap electrical tape around any bare wires. The canbus has no affect on the side buttons. But if you suspect a problem with the canbus, you could temporarily disconnect it. I suspect you have a defective capacitive button, have you contacted your reseller?
[Android Head-Units] shadxw:
My s5 unit keep crashing CarLink when using carplay/android auto(wireless).Sometimes after 5 minutes of using, sometimes after 40+ minutes.All units are like this, or only mine?I use carlink because it has better audio quality than bluetooth music or youtube app.
[Android Head-Units] MauriBixio:
To use ONLINE music apps (Spotify-Youtube etc.) it is not necessary to use Carlink\AA, you can do it by directly launching the same apps from their icon on the radio.

For offline music, if you don't want to use BT you can load your songs either into the radio memory or into a USB drive and listen to them directly from the radio internal music player app or third-party apps, e.g. Musicolet.

So what's the real point of wanting to use Carlink\AA if it also causes radio malfunctions?
[Android Head-Units] shadxw:
The sound quality is better on carplay/AA.
[Android Head-Units] MauriBixio:
Absolutely not.

Streaming apps like Spotify--Youtube etc. they are IDENTICAL whether used alone or through Carlink\AA, so the sound quality is equally the same in all cases.
[Android Head-Units] shadxw:
I just tested that again and it looks like the qulity is better on android auto because i had dolby atmos active.If i turn it off, the quality is the same.
[Android Head-Units] MauriBixio:
AA doesn't work miracles on a stand alone application...but think what you want.

Or:

Is it better to have the radio working or with AA that makes it crash?

Hello everyone, French user of an S2 model, I think it's not a bad product. I think there must be a way to optimize all of this. I'm going to read the 200 pages of the subject to see if I find what I'm happy with. But I have a question: based on the screenshot, do you think the product is up to date or can I find more recent firmware? Thank you for your opinions
[Android Head-Units] MauriBixio:
This is the specific thread in which we talk about firmware and MCU files for these Sx units.

You can find everything here with updates up to today, just read (carefully).

No, your unit is not fully updated.

[Android Head-Units] Clyde72:
My unit still runs on April firmware and is doing fine. If everything is working fine why should you update and risk a lot of hassle 😉.

There is also some hardware modding possible without needing any updates. Depends on what you hope to improve...
[Android Head-Units] chris83210:
Hello yes you are right but I tend to always want to update my equipment. That's what old geeks are :)
[Android Head-Units] marioti:
maybe you can try to listen an old truth, that better is the enemy of good :)
[Android Head-Units] Clyde72:
We are as we are. Maybe I'm less geek 😉. I agree that the unit isn't that bad. I'm enjoying it every single ride for nearly a year now. I did some modding (cooling & mic) and only some known stable major updates. But I started off with limited 2910 firmware on an older hardware model...

Bienvenu et bonne chance (courage 🙃) avec la lecture!
[Android Head-Units] chris83210:
Thank you for your response :) Yes, I find it really very good and I really have to look at each setting to fully understand and optimize this car radio. I'm already looking into changing the music player because I find the management of mp3 folders/tags not very practical. But I look at each message on this subject ;) Maybe I will find what I am looking for. Good day

Hi! Have you been sent a Teyes CC3? I want to finally see an adequate comparison) and not just the words mmm I have mmm she is better in everything mmm all throw out your galim tape recorders and buy Teyes mmmm...)))
[Android Head-Units] marioti:
Unfortunately no. It is the longest time so far, which I have to wait for shipping. It's now 34 days.

This is the first thing i don't like. I had to pay 60usd just for International shipping, and wait so long
[Android Head-Units] xdsbx:
Mekede is the same. Better support because of fyt.
[Android Head-Units] MauriBixio:
Purchased through Ali Teyes official store?
[Android Head-Units] marioti:
yes

And this is annoying, because eg. for ossuret hu, i waited just 11 days, shipped also from China, with free shipping
[Android Head-Units] MauriBixio:
Doesn't Teyes at least offer a cash back bonus on future purchases if they don't deliver within a predefined (x) time?

Many Ali sellers offer this in recent times...but, therefore Teyes takes too long to deliver the goods...also charging for shipping (and at a high cost, as you write).

Bad...I hope their radio is worth at least all this. Keep us informed.
[Android Head-Units] Astralech:
I had the S7 from Ossuret with shipping from Poland in 3 days. You said you bought Teyes, so I also bought M6PRO, which had been tempting me for a long time. I took the risk of buying from some new account marked only M6PRO 2K for VW for $200 net, free delivery. It was sent on September 10 and since September 27 it has already been subject to customs in my WER. If it is M6PRO, it should be at least 4/64G.

[Android Head-Units] inscriber:
Here is what ossuret says about 4G and screen problem.

"The 9-inch and 10-inch machine may experience jitter and color distortion or black and white screens when connected to 4G. Restarting can solve this problem, but it will continue to occur repeatedly in the future. The reason is that the 4G video signal is mixed with the screen drive IC signal of 7705N and 73217"
[Android Head-Units] senzatiOn-:

hello, something quite strange is happening to me since updating the firmware and MCU of my S2 in terms of the remote display of my C4 Picasso. Before the update (which is excellent) I had just 2 small lines of CD mode (connection type for this car radio apparently) displayed on the screen and now I have the message "wait" constantly. An idea of the problem ? Do you think this would come from the MCU or the firmware?
[Android Head-Units] senzatiOn-:
replace display and touch - will not work 100% .. Changed several users and it didn't help.

Low cost and simple solution for now is mobile hotspot or USB Modem .

Without SIM I'm using 3 weeks without problems and restart. Without cutting cable red cable from SIM slot

If he found problem...maybe will be and solution.

[Android Head-Units] ghost_kato:
Hello, I bought an S1 model for a friend, work good but i have two questions.

1. bluetooth function. Android phone, importing contacts from the phone went well, you can select and call contact names on the radio. But if I call the radio, the name of the contact does not appear, only the number.

2. Is there any way to display the car model with an indication for parking sensors when reverse gear is engaged? when the reverse gear is engaged, only a message pops up saying that the camera is not connected. The Škoda car only has sensors without a camera, the sensors beep but do not show the distance between the obstacle and the car like on the original radios.

thanks
[Android Head-Units] Barykelo:

Today I received display replacement. Let's see is the problem with 4g slot will be fixed. I keep you informed. First impression is that back frame is metal and there is no removable covers for microphone. Maybe it's new generation screen.
[Android Head-Units] Clyde72:
I have my unit for almost a year now and I'm still a happy user.

One thing I've learned is from time to time nav apps crash or system freezes when connecting to internet (hotspot over 4G) and wanting to start a trip/drive/ride.

Meanwhile I know this means I just have to do some app updating via Google app store ASAP. Then I park, manually connect to an (open) wifi network, open Google Store and do all app updates completely at ounce. Only takes some minutes mostly.

After that, I can take the road/start moving again hassle free for weeks on end.

Otherwise the unit will keep trying updating apps over hotspot/4G every following drive giving issues. Esp when e.g. while I'm driving using Waze or Maps or Spotify the unit is trying to update Waze/Maps/Spotify in the background. They're is a logic to it... (Turning off auto-updating doesn't seem to work btw)

Just wanted to share this experience/learning. Don't go directly about updating system firmware and mcu blindly everytime you experience some crash or freeze. Check the obvious first. Do some app updating/maintenance while staying connected to internet stationary (when at home or when parked wherever).

I am still on April firmware and all I have to do over months is do some app updating/maintenance from time to time. In fact the same way my phone or tablet needs updating apps from time to time when connected to a stable (read non moving/non ever switching) internet connection.
[Android Head-Units] marioti:
You received an IPS screen,

It should be way much brighter
[Android Head-Units] marioti:
Finnaly I got my package. Now I need to find a time to install it in the car, and do some practice tests
[Android Head-Units] MauriBixio:
Hizpo sent me a new screen, to see if it solves the low brightness problem of my S8 unit,without touch panel, which I purchased separately, based on GOODIX GT911 chip, which must be "glued" over the new screen, with its adhesive on the back of the touch panel.

Well, you write in the posts above that the replacement screen "could" be IPS instead of QLED as the S8 unit has as default.

Requests:

1) How do you deduce that IPS has greater brightness than QLED?

2) Furthermore, is it possible to identify (example code on the screen or another way) whether the new screen is IPS or QLED?

Few users ask for test (measuring temperature) with different thermal pads on CPU.

Blue thermal pads 6.0W/mK

(https://www.aliexpress.com/item/1005002842166246.html)

Used 1.5mm and 3mm

Load: ~70°C

Idle: ~40°C

Pros: Keeps consistency, not crumble with pressure.

Cons: Low thermal conductivity

Grey thermal pads 21.0W/mk

(https://www.aliexpress.com/item/1005006011121996.html)

Used 1.5mm and 3mm

Load: ~60°C

Idle: ~35°C

Pros: Good thermal conductivity

Cons: Crumble with low pressure, like old thermal paste.

Coper thermal pads

(https://www.aliexpress.com/item/1005003012265397.html)

Used 2mm + 0.5mm + Thermal paste Noctua NT-H2

Load: ~50°C

Idle: ~30°C

Pros: High thermal conductivity

Cons: Needs cut/brush/grind to fit with CPU/case

2mm and 1mm

2mm + soldering tin (you can solder pads together on pan if you don't have air blow solder)

Cutted/grinded/brushed from 15mm/15mm to 12.9mm/13mm (hole around CPU is not square)

Coper thermal pads + Grey thermal pads 21.0W/mk

Same result as only with "Coper thermal pads".

Conclusion: Use only copper thermal pad with quality thermal paste. It needs more DIY stuffs but you get the best thermal result.

great job. I just wonder what i was doing wrong, because my experience with copper plate give me higher temps as with just a thermopad. Copper plate was 1,5mm (in my case measured gap was 1,8mm) with two sided thermal paste MX-4

But in the end, i made an air duct, lead direct in the fan area, reverse the fan (to blow inside), and since then i didn't get a higher temp as 65C, but normal is ca. 38-40C
[Android Head-Units] senzatiOn-:
Yes, is temporary.

Hello all, it seems that there are some QF001 owners out there but not much informations. So i will try to collect everything and put it at one place. The original manufactor is shenzhen jitu technology co. ltd. These units are sold from...

I got an external microphone from the seller, and inside is a cylinder mic with such size.
[Android Head-Units] Bastianino:
hi, I have a problem with my S8, everything works, parking sensors, dashcam, rear camera, the steering wheel controls DO NOT work, I set the canbus as the seller told me but nothing works, do you have any suggestions? I attach to the photo of the canbus, my car is a 2018 Renault Captur
[Android Head-Units] MauriBixio:
Only hypothesis:

You have radio canbus decoder doesn't work (relating to car to decoder communication, and only for the steering wheel controls, but this would seem VERY strange to me...) or your steering wheel controls are of the resistive type, and in this case you will not be able to communicate with them via canbus, but use the 2 "Key" input wires present in the radio wiring, and therefore you will have to physically connect them to those of your steering wheel...

Is the setting in the radio for you canbus \car\model correct?
[Android Head-Units] Bastianino:
Thank you for the reply, the settings recommended by the seller are these in the photo, but out of desperation I tried ALL the Renault and Dacia settings, without results, obviously online; How can I know if my controls are resistive?
[Android Head-Units] MauriBixio:
I don't know Renault car... but if you write that it's 2018, the communication of the steering wheel controls is almost certainly via canbus (remember that the canbus protocol is NOT the same for every car Brand).

But, from your photo of the decoder supplied with the radio it seems the manufacturer by LZ, so would try (it costs nothing to try) to set the brand in the canbus settings:

"LZ/Renault/your car model" or something similar...

If this doesn't work, perhaps your decoder is faulty, in which case only the seller will be able to help you by sending a new Canbus decoder.
[Android Head-Units] marioti:
Do you have an extra plug on power cable, like in a pic.

If so, disconnect it
[Android Head-Units] Bastianino:
thx, I tried LZ but Renault Captur is not present, so I bought a hiworld canbus and it doesn't work, now I'm waiting for the new "simple" canbus to arrive, certified for Renault Captur, I'll try it in a few days; I tried to put the original radio back in and the steering wheel controls work; I suspect a connection was made incorrectly, is it possible?

thx, tomorrow I'll dismantle the radio and check this connection, thanks for the suggestion, I can't do it now because it's dark ;)
