[Android Head-Units] Martin 12:
I read the last two pages as you argue)) You are correctly told in the comments! Volkswagen, like Skoda and the like, does not have two FM antennas, one FM, the second AM! I have multivens and antennas located in the mirrors, in one FM and in the second AM. You are checking it in a strange way, naturally from the AM wire it will catch the FM station, you can just plug the wire for FM and pull it out onto the roof and it will catch, the second question is what quality is the signal.

As I understand it, you finally figured it out))

Most likely, you previously had a 12 volt signal from the radio through the antenna.

Only I didn’t understand where you found the wire on + please explain, and where you connected it. Can you elaborate? Since all systems are different, most have an intermediate unit between the antenna and the radio.

I adjusted the equalizers using the phone, so now everyone probably does. The microphone you are talking about is more expensive than a radio, it is at least not advisable. I think that the people sitting in this thread will not set it up differently as through the phone, there are too many adjustments, and they will not buy a microphone. But to adjust the delay, only hearing will help you, although I like the factory surround sound setting, but I'm not a pro.
[Android Head-Units] Jeka1400:
If the units of measurement on the delay controls were duplicated in cm (as it is done on Teyes), then setting it up is not a problem at all. And it is certainly difficult to see the changes by ear. And even when setting the delay, you have to periodically reset to the default, since at some point the response to the adjustment and on-off of this function disappears. Only reset helps.
[Android Head-Units] Elrathias:
So buy bigger battery, or lower volume on amplifier.
[Android Head-Units] Martin 12:
Yes, I agree, I didn’t understand what the units of measurement are, it’s probably written how much earlier to work, in general, hell knows, in general, I installed it from the manufacturer, it seems normal.
[Android Head-Units] Astralech:
There is voltage on the blue wire B1-AMP, the fan is connected to it and works all the time. +12V for the antenna is on the power connector "G" marked ANT also the blue wire "G8". I have a powered antenna from it.
[Android Head-Units] Martin 12:
Where did you connect it? This is if you have an active antenna and it has a connection to 12 volts? Do you have an adapter?
[Android Head-Units] Aaantonn:
Where is this wire included in the menu, can you elaborate? He probably in the settings of 8888 at the very bottom is signed as an amplifier?
[Android Head-Units] Elrathias:
Sounds like you have connected LOW LEVEL OUTPUTS instead of the default wiring speaker level outputs on the harness. Ie, wrong wires for a non-amplified car
[Android Head-Units] Elrathias:
Having soooo much trouble with this, all three latest fw updates.

Using hizpo special obd2(ie another cheap elm327 clone running the fake v1.5 instruction set) it has insane problems connecting to torque and acctually staying connected. I think carletter android auto is blocking it, due to overriding bluetooth connection stack, but im working on putting together a proper bug report for jitu tech.
[Android Head-Units] Elrathias:
This happens when car has amplifier and is expecting low level output from stereo, and you give it speaker level outputs. Ie source => head unit => head unit amplifier TDA7850 ≈15-50v => car amplifier ≈x4 === VOL 1 around 60dB instead of 36-38dB.

Depin speak output cables from canbus harness and splice in the low level connections from HU onto those now loose pins. Use bullet or insulated spade connectors if unsure.
[Android Head-Units] Astralech:
I cut off the plug from the antenna cable and soldered the cable to the signal wire. The power from the G connector ANT cable is connected to the antenna through the filter (C + 3xL) removed from the Fiat radio.
[Android Head-Units] Aaantonn:
Yes, just go to the bluetooth on the radio, further to the right are the settings and change the password to the password from the OBD. I have the most common OBD 1.5 for $4 and everything works great. The only thing I use karista, and it can not be installed on the car radio.

@marioti

aka VW/VAG "diversity antenna"
[Android Head-Units] marioti:
My car is Skoda Superb 2012 - as it's stays in my signature

I have oem 3C0035507P fin antenna. With this the car left the factory. This antenna got 3 plugs. DAB, GPS, AUX Heating. Don't have DAB so it use only gps and webasto. Radio antennas are builded in side rear glasses

I have to say, with this antenna GPS sees average 28-29 satellites with 24-25 in use.

Radio amp / separator is powered by blue wire named "amp" and it's connected to G8 (see pic.) On stock settings it wasn't active. I have to go to Factory > 8888 > pos. 34 (penultimate position, i guess)
[Android Head-Units] peibol:
Hi guys!

Anyone tell me where can I buy this unit?

Thanks !!
[Android Head-Units] Clyde72:
My car is the original Golf MK5 2008 version without satnav/satelitte, it was delivered like that from the factory with a whip antenna on the roof.

Now I have on board satnav ;), it is one of the reasons I bought this HU btw. I was a bit suprised that you've changed RNS315 for this HU. Is RNS that bad?
[Android Head-Units] marioti:
Depend what you expecting for. For my needs RNS315 is pretty bad. Touch screen only 5", in res. 400x240 pix. Navi maps don't had actualization since 3 years, and no one know if they will be. Whether that, navigating was just bad.

You can't use any android auto aux modules.

The only pretty good thing, is the bt connection for calling and music streaming and of course good (standard FM) radio receiption

Hello, I bought a Roco k706 S3 on Ali, and after two months of use it got a black screen. Any suggestions on how I could access remote? Wanted to enable secondary monitor to use av output.
[Android Head-Units] kylegrant:
Ali Express
[Android Head-Units] peibol:
Yes, but where?
[Android Head-Units] kylegrant:
just search for your car model and stereo (for me - mk6 jetta stereo) and you should be able to find a few
[Android Head-Units] Clyde72:
Thx, glad I've stopped looking for an second hand RNS and fell on this cheaper alternative then. And as you said I also preferred an more "open" android based unit, I had allready heard & read stories about map updates etc...
[Android Head-Units] Jeka1400:
Do you have direct contact with the manufacturer?
[Android Head-Units] Jeka1400:
I did so, it does not connect
[Android Head-Units] Elrathias:
Sorry to hear that it didnt work for you, it was the method i used to get mine working after updating fw to late february release.

Trying to connect my S5 to my ECU Bluetooth module. It has a pin and but it does not ask for it when I try to connect.

My phone can connect just fine and it asks the pin when I do.

Any fix?
[Android Head-Units] Aaantonn:
Go to the bluetooth on the radio, further to the right are the settings and change the password to the password from the OBD
[Android Head-Units] Elrathias:
Looks like loose cable, check connection on socket and motherboard for loose pins
[Android Head-Units] longhiw:
Thank you for your suggestion, but the flat connections had already arrived. I did a test by connecting the display directly to the board and still no image.
[Android Head-Units] Elrathias:
This does not look correctly seated in socket

To change the km/h to mph on stock launcher, press and hold the speed/kmh. You'll get a pop up with option to change to mph.

Remove the power cord and reinsert it and restart the unit without removing the screen

So i got a new head unit and it seems the MCU version starts with QF03 and 2023-03-15. Has anyone seen one of these and is it still possible to update the system version to 4.11? Current sysversion is QF001.20230304.121526_v3.4802 and MCU is QF03.V01.01.20230315.002121. Also DSP is BU32107 and Radio is TDA7708.
[Android Head-Units] MarcelloR92:
Potresti avere la nuova versione MCU che ha? @Clyde72
[Android Head-Units] marioti:
I install basic version, and it says that app is not compatible, and the plus version won't be neither

i've just found out this app is made by our user, but only for FYT based HU.

I asked KoTiX2 about Radio app, he is the creator of this app. He buyed a QF001 unit and will be working on it. But still, it take him some months

[Android Head-Units] super_paws:
Anyone aware of how to adjust display size or DPI?

I find Android Auto a bit too small/dense on the 1280x800 screen.
[Android Head-Units] pohatta:
Does not work. It says "connecting" and then "unpaired" PIN is 100% correct.
[Android Head-Units] Elrathias:
There is a bug related to dpi and resolution with android auto and android 12/13,

However, if you enable developer options on your phones android auto page, you can manually set resolution.

I recommend you use a square of default resolution due to how the HU gpu handles up and downscaling (ie 640x400 instead of 1280x800)
[Android Head-Units] Elrathias:
If you have problems connecting to other than GSM/Edge, check antenna cable and connectors. make sure you didnt connect GPS antenna to 4g connector and vice versa.
[Android Head-Units] Elrathias:
Bluetooth stack is customized, so you need to connect to the OBD2 FIRST, and THEN phone. else it throws errors like its armageddon.

very annoying.

Also, dont leave the OBD2 reader in car, insert it after HU has booted up.
[Android Head-Units] pohatta:
It is not an OBD reader. It is a Bluetooth module inside my standalone ECU to read every sensor and even make adjustments to the engine directly from the radio. It just does not want to connect.

I do not have my phone connected to anything, I only tested if I could connect my phone to the ECU Bluetooth module and that worked just fine so the issue is in the radio, not that bluetooth module.
[Android Head-Units] buggme:
I did. GPS works. No service with no bars. But as soon is I installed the Simcard it show AT&T in settings. But emergency calls only. I changed to every APN settings I could find. With a reset in between. Pulled the power also to do a restart. Drove close to a tower. My phone was getting like 100m DL/UL speeds. No luck so far.
[Android Head-Units] esmeraldo18:
I have Hizpo S2 model, do you know if 360 view can be implemented?
[Android Head-Units] blue_one:
As already stated before the head unit only connects to a few Bluetooth device classes like handsfree, btaudio or some obd dongles. The manufacturer of the head unit did not open the Bluetooth stack for all devices. So Your ECU isn't supported pretty sure.
[Android Head-Units] Elrathias:
demount the unit, and connect a small car antenna from walmart or equivalent, one of those old school window mount versions, and see if maybe you got a bad antenna. https://www.amazon.com/Bingfu-Adhesive-Antenna-Cellular-Amplifier/dp/B07ZYQ7FY8/ something like that should suffice.
[Android Head-Units] Elrathias:
Then that is your problem right there. if your custom ECU has internal bluetooth connectivity, and it is outside the spec and compatability of the head unit, you cannot use that source. i suggest you connect to your phone, and use an android auto compatible torque-alternative as a workaround.
[Android Head-Units] Jeka1400:
Only with an external 360 device
[Android Head-Units] KoTiX2:
It seem that i need root to be able to start working on this unit...

The wifi ADB that come with the unit is unreliable because when transferring the files it shutdown the wifi connection.

I also tried the USB debug but it couldn't connect to my windows11 PC...

Not a good start but i'm sur ei'll find a way ;)
[Android Head-Units] MarcelloR92:
How did you manage to activate ABd WiFi? I can not
[Android Head-Units] Clandaries:
Just read opening post ;)

- wireless ADB is enabled by default with root user. 🎉 The port is 9876. ( I've found that inside the build.prop)
[Android Head-Units] marioti:
I think [B]blue_one[/B] can help (i hope). He was the first to found out eg:

" wireless ADB is enabled by default with root user. 🎉 The port is 9876. ( I've found that inside the build.prop)"

so if the wireless method is available, i hope the wired one is also possible
[Android Head-Units] Clandaries:
I think we have to use points on the Mainboard of the HU. But i am not willing to destroy the S8 even if it is not working 100% with our Suzuki cars.

There are some points on the mainboard that seems usable to connect it to a PC
[Android Head-Units] KoTiX2:
Yeah i can c

Yes, i can connect with wifi adb but as I said it's inconsistent.

I'll try to update the firmware/MCU maybe they fixed that (crossing fingers)

I did only some quick tries yesterday maybe I'll find out why debug USB is not working for me. Maybe it's just my new PC... I'll let you know ;)

EDIT: the wifi connection was not stable at all. it didn't depend on wifiadb.

After updating MCU (firmware too but the MCU was the problem) everything work as it should.

A bit slow but it work.

Adb connect ipnumber:9876

I've installed the Hizpo S8 in my 2015 2 door Wrangler that has the Alpine premium sound. The unit was pretty plug and play but I get very low volume out the rear speakers and I can't find a diagram for the 2 door. The fronts\tweets and sub are fine. I've tried both the wire connectors that fit the Mopar plug. No difference in sound. Fader doesnt do much aside from turn down the sub and front zone. Support recommends a factory reset but that has been done, as well as the latest updates found in this thread. I'm wondering if there is an amp for the rear bar speakers that isnt triggering.

in my case i notice that the gsm reception is poor compare to my phone. In both i have sim from the same network provider. Antenna from HU is mounted inside dashboard. But above this antenna is only 4mm dashboart plastic. My windshield doesn't have a heating or so, which can interference.

So is there a way to buy and mount a better antenna? but i don't want anny roof whip antenna :)

[Android Head-Units] Clyde72:
Finally did a mic adjustment. I removed the pcb & capsule from within the OEM Vag mic housing & put an 6 mm capsule from an old Parrot mic in place. At the radio end/center console side I made an adapter to 3,5" mono jack (so it is the pcb/circuitry preventing the OEM VW mic to be used with aftermarket units).

So I have my external mic now sitting at the designated location in my Golf MK5 without need to run any extra cable. And normally it is future proof if I were to change to another aftermarket unit. I unsoldered & removed the internal mic of the HU all together btw. Good riddance.

Works very well - better than the internal mic mod did. And no more mic picking up the (low) fan noise.

Edit: inside the OEM mic housing there is an small pcb which has a 6 mm mic capsule soldered directly to it. If one is carefull in removing the guts (pcb with capsule) you should be able to repurpose the capsule. I was too brute and broke the capsule's solder islands (but I knew I had another 6 mm mic capsule laying around if needed)

Could also be simplified by just cutting off the OEM mic housing and soldering an external mic directly to the OEM connector leads of course. And make an adapter to 3,5" mono jack to connect to external mic socket.

Hello, good afternoon. I wanted to ask a problem. I have the external microphone on for Bluetooth and it sounds very bad. Is there a solution to improve communication?
[Android Head-Units] marioti:
With bluetooth mic, i gues you can't do anything. Just use the built on, or external one, for ex. like Clyde described few post up
[Android Head-Units] amesino:
Yes, but I can't find the publication. If there is a colleague who can tell me, I would appreciate it.
[Android Head-Units] Clyde72:
You can do a search in the thread - at the top of every thread page - and do a search for "mic" and you will find all the posts dealing with mic & mic modifications.

In general there are two options, or choose for the internal mic mod (closing a gap) or the external mic mod (dissabling the internal mic). External mic is best a wired one. There is one delivered with the unit depending on your model. Most OEM built in mics are not compatible btw.

I've tried the internal mic mod first as I didn't feel like running extra cable. I wasn't pleased with that mod and wanted an external mic but without running extra cable so I went a step further and examined the OEM mic closer and modded it (VAG car) to use it with the HU + I removed the built in mic from the unit.

That OEM mic modding I did very recently. Result is superb, finally quality hands free calling and speech/dictating (for navigating eg). I can recommend it for every VAG car owner here. May even be possible for other car brands with OEM mics I guess.

Hi,

Since yesterday I have the problem that I have a black screen. buttons on the side work the touch too. but I have no picture. I had that 2 days ago and during the 5min drive I got a picture.

Is there one here that has the same problem?

and can I upload a new update via pc maybe it's because of the bugy software

[Android Head-Units] Clyde72:
There is no possibility to connect to an pc.

You also mention buggy firmware so did you install it while we adviced not to?

You could try automatic update to the latest system update or try resetting the unit with the reset pinhole and see if this solves things.
[Android Head-Units] SonGoten!!!:
I have the update 0408 all the time wanted to do the new one but I haven't yet. Can you explain to me how the auto update works? or the one with the reset pinhole
[Android Head-Units] Clyde72:
I don't know your HU model but with mine there is a reset pinhole on the right top side.

To auto update (or maybe consider a downgrade to a known stable fw version) rename an firmware "update.zip" file to "update_auto.zip" and place the file in a QF folder in root of a Udisk. Insert disk & start up the unit & cross your fingers... If you use an Udisk with led indicator you will notice it flickering if the unit is reading from the Udisk.

As I have decent mic functionality now I would reconsider Toppal AI as I do not have SWC. But first Toppal would need to support Dutch...

A question though to those who have a subscription to Toppal AI. Does it support voice controlling third party apps like Waze or streaming music apps etc? Could you for example ask "hey Top, open Radio Paradise and start playing"? or open Google calendar etc

You can view the list of available commands by entering the Topall Ai program. There is a description of the available commands depending on the license level. The commands that he knows in the database, he executes quickly enough, but what requires a request from the server is quite long and not always from the first time. Well, in general, if I need, for example, to lay out a route, it is much faster to go to the navigation and press the microphone icon already there. Played with it for a while, now abandoned it. And the quality of its work depends on the firmware version of the radio, the newer the better.
