in my case, i can have my cell as a hotspot, if i set it on the dash directly above the unit, thats not more than 1.5" directly above it. once connected move my cell to the back seat connection is lostl.

take unit into my house power up, in my kitchen it can not see my wifi that is 10' away,

i had considered firmware update may or may not make it better/worse, hoping better,

if i am reading these firmware numbers correctly , what mine came with is more current than other posted here, and the update sent me is very current date wise. i will be installing that with in 3 hrs and post results.

i have tried as mentioned, the tiny blue antenna wires, bent at 90 left and right, 90 up, 90 down, straight back etc. every angle possible. made no change.

to view the lengths as also mentioned, any picture i can see of that C connector and the wires mine are 1/3 shorter than any pictures posted. i noticed that weeks ago, tried extending them 1/2-4" made zero difference. the thing is bluetooth is a non issue
[Android Head-Units] Clyde72:
Possibly it will but maybe try the 2611 system update first

I love my new boot logo. Maybe I will disable the sleep mode to see it everytime I start the engine. 😂
[Android Head-Units] TTVR6:
apparently none of my usb ports even work. that is one item i had not even connected or tried yet beyond plugging the cell into see if it would charge when connnected. it did not, and at that point i didnt attempt to check actual cell to unit connection, i had no need to. i just figured it was not capable of charging or settings turned off. which is of of the 3 items this upgrade was suppose to address.

i tried both rear usb ports as i can see no sd or front usb.

code 8888 only brings up usb versions to select, no where do i see turn on or off any ports or which to make master. so my results posting on this update wont be any time soon. it takes a day or more to get a reply from china.

anyone have any insight as to how where to turn on usb ports? and associated codes required?

one thing i happen to notice on my box unit came in. two addresses of dealers or perhaps service techs for where these are programmed and shipped from? london and germany. the overall box where you would expect to find contents model number labels etc are all wrapped by this other set of labels.

i was checking to see if box contained any actual model, version number.

wondering how significant those addresses and websites may be for tech info

if any
[Android Head-Units] Clyde72:
@blue_one As you know I successfully upgraded my S4 with DSP BD37534 with the 2611 system upgrade you've shared. My DSP stayed the same. What is the DSP of your S8 in fact?

Cheers
[Android Head-Units] kabelgleichung:
Thanks, I wired it that way, but the unit does not start. It consumes around 30mA when wired that way, so it seems to stay in standby.

It starts up when connected in my car and ignition is on. So it seems that it does indeed needs CAN to power up.

I got the Ul 7867A off ebay that fits the Sicon xD with 4g lte.(if you search scion xb 4g lte radio)(it will come up with what I bought)

All I'm getting is Egde(2g) service... I have tested 3 Sim cards for ATT that works on my phone/tablet and even a USB 4g lte dongle.

But no change. I tested a 2nd antenna. Tried every APN settings searched, drove close to a att tower, tried 3 different firmwares. Tried looking in Factory settings 4455. Etc.

2g is no longer available.

Any firmware/software etc that I can look at?

Also the GPS speeds are in KM/H. On stock launchers.. I like the stock launch is there a US version of them?
[Android Head-Units] Scofi003:
Ciao ragazzi, ho un’idea per quanto riguarda l’antenna gps, che ne dite se installo questo cavo doppio e aggiungere un’altra antenna? Secondo voi funzionerà?
[Android Head-Units] Meteordust:
English please: Hi guys, I have an idea regarding the gps antenna, how about if I install this dual cable and add another antenna? Do you think it will work?

For the money maybe nice to test.

Somehow I think that two signals and with a little distance offset from the same satellite(s) will confuse the GPS software, never tested something like this, so who knows :rolleyes:

But it will not boost your GPS reception I think, if you put two GPS antenna's in your car, they are both still limited due the car construction.

But not tested is not known, so let us know.....

Hello, i have a S5, someone know how to root the tablet ? i need to modify the animated boot logo :/

How to disable adb from wifi ? the recent firmware is again in debug mode ? how to more secure the tablet ? thx
[Android Head-Units] Lione2:
Hello,

i finally order S5 model for mazda 3. Cross fingered!

The only way to update it is via usb ? Not OTA ?
[Android Head-Units] marioti:
read the first page
[Android Head-Units] freman5:
Thank you, how to disable wifi adb after finish operation ? i can only access it on localhost ? because i have 4g internet on it :/
[Android Head-Units] freman5:
I notice a slight delay in updating the speed displayed on the tablet, how can I improve it? Sometimes I even see 20km/h when I'm not driving x)
[Android Head-Units] marioti:
Only way is to improving gps as far as it possible.

First - read the first page you find how to make some changes in settings.

Second - change the antenna
[Android Head-Units] freman5:
thank you, i think before, the speed was get from canbus not from gps... And i see more bug with speed after apply the new setting in first post, maybe i need change port to unsecure, because i change for secured port...
[Android Head-Units] Meteordust:
What is written in first post is working well in many of our devices, port 7275 and 7276 both do the same....or actually nothing.

Dont change other settings on that factory 5544 pages....

What bugs you talk about....look at your signal strenght, how many satellites visible, what accurary...

Where you place antenna, is signal strenght for at least 7 satellites above 35 %. and green.

My car sees 20 to 27 satelittes with 2 meter accuracy, gps fix maybe 20 seconds after boot to homescreen, never really heard real problem with gps.

No. Have Mazda6 GJ -13 w tomtom navi.

Everything works though.
[Android Head-Units] Elrathias:
Define good, define decreases.

Typically id say ambient noise level in car increases, and percieved audio volume decreases - but there might be different things happening.

What unit, what car?
[Android Head-Units] simetra1:
now like this. The first time I start the car the sound is loud again until it moves high. It drops a little when I move. It doesn't go up when I stop again.
[Android Head-Units] Lione2:
Great news, can't wait to test it
[Android Head-Units] Clyde72:
OTA doesn't work and between us you wouldn't probably like it to have to go and fetch 1,9 Gb over 4G from chinese servers 😉. Downloading the files to pc with fast ethernet (in my case) can allready take its time. Once downloaded updating via usb is quite fast, only some minutes... + it gives you more control over the process (checksum etc...) imo
[Android Head-Units] Elrathias:
Cut cable and add in resistor, rheostat, of computer fan controller board - whatever is easiest for you. Fan runs on car voltage, ie 14.4v = overspeeding and LOUD.

Id probably buy this 2-pin variant and make it fit if connector is different: https://vi.aliexpress.com/item/1005004945274989.html

27ohm resistor so 14.4v should draw down to ~11v, itd be something atleast. unless you live in texas or some other REALLY warm place, id probably opt for a 48ohm resistor. Anyways, its something - and more than going full passive.
[Android Head-Units] Lione2:
You're right. I imagined not having to make a hole in the plastics industry to pass a usb cable but it does not matter. it's easy to disassembly frame on mazda 3, i will update time to time like this
[Android Head-Units] Elrathias:
https://www.aliexpress.com/item/1005003792120414.html

Screen is universal product, digitizer and frame is not.

However, this store sells them: https://qvkscreen.aliexpress.com/store/137464?spm=a2g0o.detail.1000007.1.a8e6612bjScaSl

To be honest id much rather get a new screen, than fiddle with a screen protector in my car.
[Android Head-Units] Meteordust:
Never tested it on stock fan with resistor, only on the Sunon fan mentioned on first page, it's as 0.52 Watt labeled on the fan I received.

I putted 68 Ohm/1 Watt resistor, with 14 volt still had 12.5 Volt, put it in line not parallel on the voltage, so 14 volt (red wire) to resistor, from resistor to + (red wire) fan.

Why the option for higher resistor in warm area?? the higher I put how slower the fan goes..?

The higher Ohm the more it eat away voltage.
[Android Head-Units] Elrathias:
Drop glovebox, squish in sides, pull out. you can reach the rear of the stereo with some flexibility, no need to make hole.
[Android Head-Units] Elrathias:
I mean unless warm, choose higher resistance. if desert, texas, other really warm and sunny place, under dashboard temperatures may approach max operating temp anyway and you might be better off just living with the fan noise.
[Android Head-Units] Elrathias:
This is weird. Please try and measure voltage on fixed volume setting, and seeing what AC voltage you get to speaker. i cannot think or imagine any software issue that would cause reverse speed-adjustment to happen.
[Android Head-Units] MarcelloR92:
@Meteordust But if I put an active sim without an active 4g connection, does the stereo time update before the GPS connection?
[Android Head-Units] Meteordust:
yes it does if your NOT active 4G card can create a network connection that can sync time.
[Android Head-Units] MarcelloR92:
So I buy a sim without a 4g connection, hoping that the time updates first
[Android Head-Units] Meteordust:
Be careful...my answer was actually a question....can a not activated sim card get network acces to sync time ..?? have no clue and no old sim card to test ..
[Android Head-Units] MarcelloR92:
I want to try to use a pay as you go sim card, with no active subscription and 4g data disabled, I want to see if the time is set automatically, when I turn off the stereo for more than 2 hours it takes more than 1 minute to find the time automatically. I followed your guide but nothing changed
[Android Head-Units] Clyde72:
I have to front USB ports on the VW model. Sorry. Maybe you don't need to make wholes in your dash trim. Look on Alixxxx for "Mazda 3 usb socket"...
[Android Head-Units] Meteordust:
This also depends all on your gps antenna reception ....when it is weak it will take more time.

And did this trick to avoid a wrong time, that chinese host displayed my time wrong...2 to 4 minutes behind compared to my phone, car dashboard display or atomic clock..but set it to supl.google.com also speeded up the gpsfix on other owners HU.

Try also to clear the cache of the GPS test app, not 100% sure but my gps fix became somewhat slower and slower, after clearing that test app it became normal again, or was lucky.

Look few pages back, @Clyde72 showed the pictures/video ..and also his experience, very fast gps time sync.

Or create hotspot with your phone, put hotspot on before starting the car.

No clue if automatic Android Auto connection will do it too ..only use BT myself for music and calls.
[Android Head-Units] Lione2:
I don't have the car yet, just based on videos on web. I will check! That give me hope

It seems it's only for latest model, it's for a 2010 model but thanks :)
[Android Head-Units] Meteordust:
That is also still my question, bought my unit in the winter...maybe in the summer I fit a larger low noise fan behind the HU to transport the heat away, so heat not staying in dashboard for long time around the back of the HU.

Sun burning on the car for a few hours can really give high temperature in the car as we all know.

Resistor is to prevent damage on the fan, better put a quality fan with resistor, so it will have around 12 volt on engine running, don't actually hear my Sunon fan running, like the stock fan did on 14 volt.

Compare the fan blades between cheap stock and Sunon, on 14 volt the stock gave less air then Sunon on 12 volt, my CPU temp dropped around 10 degrees, this because higher static pressure and airflow, design of the blades makes the fan.
[Android Head-Units] Clyde72:
Running an extension to glove box or passenger side are indeed also options. There are gaps. It's not all hermetically closed...
[Android Head-Units] Elrathias:
If unsure about resistor, use rheostat. Some minor soldering, but a customizeable solution. Resistance increases with load, so measuring no-load resistance isnt really avcurate. I think you can probably go all the way up to 90-100ohm and still get enough cooling, but meh, 40-50ohm is middle of the road and should be good enough - theres a solid sound barrier after all

Dont forget that running the AC in summer drastically lowers sub-dash temperatures due to heat absorption from air ducts.
[Android Head-Units] Clyde72:
The AC ducts is what I am counting on too
[Android Head-Units] Meteordust:
Don't now the price yet of the gasoline in the summer ..to run the AC 🤣.

And yes I wait also till the summer before doing unneeded stuff.
[Android Head-Units] Clyde72:
I have my Climatronic on all year long, no idea how much fuel it consumes actually, it's comfy though. The trick in summer is to put AC temp about 3 degrees lower then outdoor temp. This cools enough. Otherwise you make the system work & blow to hard and it is even not comfy.
[Android Head-Units] Meteordust:
Was a little joke about the fuel prices, crazy world these days, but you right, I keep 5 degrees as difference above 30 degrees, below I open a window, not really like the dry cold air, but everybody their comfort he likes.
[Android Head-Units] Jeka1400:
I have an active, but unpaid SIM card. I’m not ready to say how it was with the clock readings before it was installed, but with it the time is relevant immediately after the start of the radio.
[Android Head-Units] MarcelloR92:
When you turn on the stereo every time does it tell you 5.00? And after a few seconds does it update automatically? Or does the current time automatically appear when you turn on the stereo?
[Android Head-Units] Jeka1400:
Tomorrow I'll check for sure, but in any case it happened fast enough that I never even saw a non-actual time.

I'm more concerned about the problem with the "sleep" mode. Until today, it somehow worked, albeit not stably, and the sleep time did not match the settings, but it still worked, but today it stopped working altogether. I reset, changed the setting, did a shutdown - turning it on in the engineering menu, nothing helps.
[Android Head-Units] Clyde72:
I'm under the impression that there might be an issue with the latest 2803 fw version by following the firmware thread a.o. I am no specialist but my gut feeling tells me to leave it sitting on its chinese server...
[Android Head-Units] Scofi003:
Hi guys, does anyone recommend a GPS antenna to buy? Better than the standard one?
[Android Head-Units] kabelgleichung:
Which file did you recompile to find the factory codes? I am currently searching for the codes in a different, but pretty similar rom.

Thanks
[Android Head-Units] freman5:
Please someone know, how i can use external battery ? for save energy from the car ? its possible to use switch, for select power from car or external usb battery ? thx
[Android Head-Units] Jeka1400:
You definitely can't from an external USB. Why do you need such difficulties? The consumption of the radio in the off state does not exceed 10mA. With this current, a normal battery will last from 1 month. My alarm system with GSM and GPS consumes from 25 to 70mA.
[Android Head-Units] freman5:
the problem is that when the engine is off and tablet on, the battery discharges quickly after 30 minutes
[Android Head-Units] skferek:
Hi everyone, my unit is S8. I've been following this thread for some time. It has proved very useful in several cases. The latest soft 20230408 has new changes: 1. SVC works 2. you can minimize phone applications during a conversation 3. data from ventilation via CAN appeared on the display, but nothing can be changed only the preview 4. data from parking sensors via CAN appeared when reversing
[Android Head-Units] Jeka1400:
Even a tablet just turned on cannot drain a working battery in 30 minutes. When it is on, the consumption rises to ~1.5A. Now, if you listen to music at high volume, then it’s more realistic to land the battery. But in such a situation, you need to install an additional car battery, no power bank will save you.
[Android Head-Units] Lione2:
I read the whole thread, so I have 2 new questions:

Did those who recently purchased a model end up with a manufacturing date after December 2022?

It is also written that the removal of a resistance improves the sound, still relevant?
[Android Head-Units] Aaantonn:
You have a radar on the screen on the left, what is this suggestion?
[Android Head-Units] Jeka1400:
I checked the operation of the clock on my radio. When turned on, as soon as the clock appears in the status bar, the current time immediately. Therefore, the presence of a SIM card, I think, has nothing to do with it. I think that for those who complain about the problem with the clock at startup, the radio is not connected correctly. As an option, ACC and BAT are mixed up in places. When properly connected, the clock should continue to count even when the radio is completely turned off. Remember any simple radio connected to a car, because it did not waste time when turned off, although there was no internal battery there either.
[Android Head-Units] Jeka1400:
Also updated to the latest version. Only the MCU had to be updated too, although the version was the same. Otherwise, it constantly hung or went into a reset. While satisfied, it seems that it works better than the previous version.
[Android Head-Units] MarcelloR92:
Would BATT be number 5 in the pattern? Do I have to reverse the connections? Do I have to connect number 3 of the diagram to BATT?
[Android Head-Units] Clyde72:
Don't confuse battery drain with idle car battery voltage. You say motor off, HU on... and being used I presume...

When the motor is running voltage can go up to over 14V. When engine is off battery voltage is around 11,8V or even 11,5V. This is normal, a classic car battery is rated at +/-12V. When the motor runs the alternator will charge the battery a.o. resulting in the higher voltage. When the motor is off charging is stopped and battery voltage drops to the nominal voltage again. Or below if something drains it... consumes power...
[Android Head-Units] Clyde72:
A natural summer breeze by opening a window is always nicer and even healthier, I totally agree on that when cruising but not when on the highway e.g.
[Android Head-Units] snaker12:
Hello,

i have installed a back camera and i also installed today a front camera. If you go at back car options is says for how many seconds to change to front view camera (5s - 15s) when you take out the reverse. I choosed this option but the front camera says no signal. There are 2 inputs to the harness where i can connect the front camera which are marked as cvbs1 and cvbs2. I have connected my front camera at cvbs1. In order to see the front camera i must choose aux from the programs menu and then the camera shows the image fine on the screen.

There is no input cable which is called front camera.

My question is do i miss any menu option about the front camera and this is the reason that it doesnt work the way it should. Should i connect to cvbs2 input which seems kind of wierd as cvbs1 makes more sense. Any other ideas?

Thanks.
[Android Head-Units] Jeka1400:
On the diagram, they are signed correctly, only in fact the wires on the connectors from the radio to the car can be mixed up in places. My complete wire did not match the line going to the side light, so I do not exclude that you have something mixed up in the same way. In any case, I would check with a tester on the connector going straight to the radio. It is also described in the manual.
[Android Head-Units] Clyde72:
Before you let people switch cables tell me if you have canbus connected?
[Android Head-Units] Jeka1400:
And how or where did you connect the power to the front camera?

In general, according to my seller, this function is not supported, but in the new firmware I see that theoretically this functionality can be implemented. I don't have a free camera right now to try it.
[Android Head-Units] Jeka1400:
My car does not have CAN BUS, but this does not change the way +BAT is connected
[Android Head-Units] snaker12:
At the back camera you get power from the reverse lights. At front camera i took from the battery itself.

The problem is that theoretically the option that says for how many seconds to switch at front camera after removing the reverse should output on screen the cvbs1 input, which is not happening in my case. And this is very frustrating. Am i missing something.
[Android Head-Units] Jeka1400:
I also planned to do this myself, but since you say that it does not work, then you need to think of other options or wait for an update.
[Android Head-Units] skferek:
Yanosik navi&radar
[Android Head-Units] Clyde72:
No, but if you would have canbus then the unit would sync time over can on startup. That's why I asked
[Android Head-Units] Jeka1400:
I can't claim to be 100% sure, but logically speaking, synchronization should not cancel the operation of the internal clock in the off state. Plus where this information (exact time) is taken by CAN BUS. Rather, the radio has more sources (GSM, GPS, Wi-Fi) than it does. Correct me if I am wrong.
[Android Head-Units] skferek:
Run adb and send command

pm grant <PackageName> android.permission.SYSTEM_ALERT_WINDOW

it will activate show on top of other apps
[Android Head-Units] Clyde72:
Because we tested this time sync issue weeks ago, with and without canbus connection (without internet connection). With canbus time seemed always in sync with the car clock on startup, even if the car clock was not set correct. After some while the time on the unit was adjusted by GPS as we figured out. It is all in the thread. Info from our testing & searching.
[Android Head-Units] Jeka1400:
That is, when starting up, the radio did not have the correct time corresponding to the car's clock, and later it was corrected by GPS? Perhaps I did not attach importance to this information, because at that moment I was looking for another))

In the one described by other participants, it is said about the initial time indication corresponding to the firmware time, but it cannot be like in CAN! This indicates precisely the lack of proper power connection of the radio.

In defense of my version, I can add that on conventional 1DIN radios, often in the wiring for connecting the bundle, there was a ready-made possibility of interchanging + BAT and ACC. Apparently sometimes, depending on the car, they are in different pins. I'm talking about standard ISO now
[Android Head-Units] snaker12:
Tommorow i will make one last test and plug the front camera to cvbs2. I must take out the dash as i have installed the radio player and it will take some time. I dont have much hope though. After some reasearch i think that this android player doesnt have a front camera seperate input and this is the reason that it doesnt output nothing on screen when it switches from back to front camera view. If cvbs2 acts like a front camera input i will be proved wrong but i highly doubt it. The cvbs1 and cvbs2 must be acting only as auxiliary video inputs and this is why i can see the camera only in aux in app.
[Android Head-Units] Jeka1400:
If anything, there are special consoles for these purposes, but unfortunately they do not support AHD cameras.
