I'm sure your seller doesn't know what he's talking about. Which is normal since he's a seller not a technical person. As said so many times, either Canbus or Key1 and 2. What he means by first connect to internet and then select canbus is because the Canbox gets its updated info downloaded from the net.

you can disable the boot animation.

Connect via adb to the Hotspot of the radio. Port is 9876.

mount -o rw,remount /

cd /system

echo 'debug.sf.nobootanimation=1' >> build.prop

mount -o ro,remount /

the radio boots a few seconds faster and the launcher then appears without delay.

Thank you for your answer, I won't waste time on this anymore, I can answer and end calls by touching the screen so not a big deal :)

In the meantime i upgraded firmware, it was 03/2023 both system and mcu, now i think it is latest.

Everything works great, very fast, looks beautiful, i'm in love with my head unit :)

I've had the S7 since March. The radio is quite ok. Since yesterday, after turning off the radio, the radio does not go to sleep for 2 hours, but turns off completely. radio goes to sleep for a few minutes and turns off. after restarting after 5 mins it is cold start. I have the soft from 2023.06.15. I uploaded the latest 2023.07.14 and nothing. what may be the reason that sleep does not work in any position.
[Android Head-Units] Alexirri:

Hello everyone,

i have problems with the 4G sim card slot with the S8.

Massive graphics problems "twitch" of the picture, up to a white/blackscreen. see YouTube video.

Video 1:

Video 2:

Radio has already been exchanged once.

I cut off the 4g card slot on the 20 pin plug, no more problems since then, but also no more internet with SIM card.

Is there a fix for this or what alternatives are there?

Thanks in advance

Greetings

Do you have sometimes or permanently this problems with screen ?

I have the same on HIZPO S7 but sometimes.

Much more on night time.. and don't know why..

First you need to update your MCU and FW.. yours is old. My HU came the same with the same OS and MCU. Now I'm using the latest version FW and MCU and these screen problems occur less often.
[Android Head-Units] marioti:
I was talking about this problem and solution (by disconnect external sim card case), since a QF03 HU owners came here. Unfortunately, as for now, no one found any other solution
[Android Head-Units] inscriber:
Have you contacted the seller. Yesterday I repaired my 4g slot that had a broken red wire on and the problems started for me too :) I sent a message to ossurate and we'll see what they reply.

Has anyone tried it with a external 4G usb cookie. I don't have one otherwise I would try.

But you can use also good aftermarket fin antenna - #1438
[Android Head-Units] marioti:
I have QF001, but I met this problem and "solution" in other forum. The issue is also described in the firmware thread. Neither Ossuret nor Hizpo gave any good solution. They said something about changing the display settings (VCOM, AWDD) but it doesn't help.
[Android Head-Units] Gyovany96:
Thanks but unfortunately my car doesn't have an gps antenna at all so I can't mount fin on rooftop since there's nothing there. I was looking for something more powerful that will get better signal from behind HU (I don't wanna reroute the GPS antenna at all), maybe I can still try a fin antenna but it's gonna stay behind HU like I said so I don't know if it would still be better.
[Android Head-Units] xxbenbluexx:
Hello,

FW and MCU already up to date.

Didn't do anything for me. If it happens while driving and I reset, it's already white/black screen again after the restart.

The funny thing is that the phenomenon never happened when I was stationary, engine off, I had been running for about 3 hours. only when driving off. After that, it also happens when stationary.

Very strange the whole thing.

But since the 4G SIM card cable has been removed, no more problems.

Not the prettiest, but I put a red wire breaker on it. That way I can easily disconnect it so it doesn't do the screen problems until a solution is found.
[Android Head-Units] marioti:

[Android Head-Units] DRDSVK11:
Hi, I have Mazda 6 2009, these buttons will not work, because they were originaly not fed to radio but to BT modul which is separate units in Mazda, and that modul is was connected to oem radio. So if you are not willing to rewire buttonts and make them resistive (I think they are also canbus) they will not work.

[Android Head-Units] b0gdi:
With the sleep mode turned off all is ok. But i want to use the sleep mode if possible.

Yes i have climate control but the unit cannot control it because this year ('07 skoda octavia) has a separate can bus network for the climate unit. Only parking sensors work, doors etc. (also the dynamic lines don't work correctly when reversing).

A CAN bus box other than the CAN bus decoder box that came with the unit?

[Android Head-Units] nyp42:
Sorry I didn't mean to question your English, it is perfectly fine BTW, and I have totally called it a CAN bus box too. I just wanted to make sure you didn't mean some other box than the one the unit came with.

The unit that I bought was specically meant for VAG vehicles and came with a CAN bus box. Did the other versions of these head units not come with a CAN bus box?
[Android Head-Units] b0gdi:
Not on initial firmware, updated to 20221216. For the moment I disabled sleep mode. To bad the unit has a lot of bugs because speedwise is super. The first bug was the buzzing noise on low volume, that resolved with the removal of a small resistor from the pcb. Also the buttons are too clicky for my taste, they double click if you press them harder. Maybe I will also take a look at them to see if I can make them feel less cheap.
[Android Head-Units] Vėžys:
Yes, they can be sold in it without canbus box.

I bought another hu, instead of this not working.

I bought a universal Mekede S500 Fyt based, without canbus box, because I don't need it
[Android Head-Units] Clyde72:
Imo especially for VAG was more about them looking and integrating visually like VAG RCD/ RNS units and that's why I chose it personally. Mine came also with can box but I disconnected it quickly because it has no added value and annoyed me with the reversing process (pre 1216) a.o. A plus is that volume button and all work as I thought them to be purely cosmetic, the more a plus as I don't have steering wheel controls.
[Android Head-Units] AlphaRadioDog:
Hello. I just purchased a ROCO K706 unit that has an S9 sticker on the outside. It is in a Ford F150 fitted bezel specific to this vehicle. It came with the harness and a CANBUS decoder. When I hook it to the existing dash harness I have several issues: It comes on and stays on with and without the key, thus draining my battery over night. 2. I have no sound at all. When I go to the CANBUS setup on the device it shows as a LZ F150 with NO CANBUS version visible. 3. The installation sheet has a note that says the the 8 Pin cable from the CANBUS adapter goes into port F on the device. That 8 pin cable does not exist out from the cable adapter.

Does anyone know if the device turns off and on via the CANBUS? I think that it might also be the reason for no sound as the external amp may also turn On/Off via CANBUS. The system in the truck is a Sony Premium sound package. Can anyone point me in the direction to solve the mystery as the eBay seller just keeps telling yes it is for a 2011 Ford F150. Thanks in advance.
[Android Head-Units] Clyde72:
@AlphaRadioDog

Maybe look on Ford forums on how to connect aftermarket radio systems and the wiring/connectors. Or a Ford garage or a car audio installer. On off has nothing to do with canbus. Neither does speaker sound. Possible you will need some additional iso adapter or some rewiring so power & speaker connectors will line up. I do not know much about Ford, always driven VAG cars
[Android Head-Units] AlphaRadioDog:
Thanks. The stock Clarion HU radio has 3 connectors and the new Double Din 9.5" also has 3 connectors but one does not match with the stock harness. Still should not the Android HU show a CANBUS version if it was connected?
[Android Head-Units] TomZol13:
I found a problem that caused the device not to go to sleep for 2 hours and more in sllep mode. The device turned off after 5 minutes from turning off the ignition. In all positions. Problem with Yanosik app. If Yanosik works in the background. If Yanosik is turned off, the radio goes into sllep mode for 2 hours. The problem appeared around August 4, so it's probably the update's fault. I'm testing. I'll let you know when I'm 100% sure

Everything works basically, but... I've downloaded "Google" app, then "Google assistant" app and when I'm trying to activate it, I should hear that GA chime, instead of it I'm hearing loud *pop* from speakers, no chime, and then everything works normally again., I can talk to it. I can listen to music, activate GA, then *pop* and I can talk. It's quite loud.

So it's working but for some reason instead of chime I hear loud pop, like speaker just turned on but on very high volume.

Any idea what this could be connected with?

I bought this 8/128 gb unit about a month ago and it works perfectly even with the latest updates. The radio is installed on a 2011 Opel Meriva B and by connecting the accessory cable with specific canbus for this car, I restored the steering wheel controls. the problem that, despite having restored the original cables of the car, the original control panel does not work. supplied with the interface cable there is a cable with black and white wire that seems necessary to connect to some other original cable of the car. I tried everything but nothing. Can anyone give me an answer perhaps accompanied by photos or videos. thank you all
