The languages are poorly translated. Third-party launchers do not work. The code to activate the logos 01010101 does not work. The only new thing I have seen is something in the volume menu, which is not a big deal either. They only release patches, it's a shame they don't try to polish the firmware.
[Android Head-Units] TorstenH:
I see. One more update not worth the effort required for installation.

I will stay on an old firmware which runs smooth by using a simple launcher not showing such a sports car which has absolutely nothing to do with the car I sit in.

I don't use one of the 0101... logos because the image resolution is too bad so I set a logo based on an own image.
[Android Head-Units] OneMisterios:
That Launcher its from other website, i test It 4 Launchers they have extract from other firmware. Its not come with the last firmware. I Will check the firmware today ,to see If he have new things
[Android Head-Units] Christod:
They are sending me a new screen. God knows when it will reach me or if it will be worth the hassle to replace it. In the meantime is there anything that can be done to reduce glare? Also can I disable warm boot? I have heard that, while the unit turns on faster, it sips power from the battery.
[Android Head-Units] jchilla:
i am actually so pleasantly surprised just how great my audio is sounding utilizing the digital output from the head unit and into this $20 dac, and then from dac output RCA's into my 4 channel amp.

Before I was using just the low level rca output from the head unit into my amp and was actually having great results too it really did sound good. However, with digital output it is just that much more clearer and fuller sounding. Especially in the low subwoofer frequencies. With digital I can clearly hear individual base notes and when the tone of the sub changes with the note being played down to the most tiniest of change in tone, it's really that clear. Before with using regular preamp output from head unit the low frequencies were muddy sounding almost as if individuals notes were blending together making it very hard to hear individual sub bass tones.

I know I'm not breaking any new ground here lol just want to share my experiences and hopefully can help someone out in the future when choosing their audio routing.

Idk why I waited several months to even try the digital output lol I was happy with rca pre outs but still lol I see now why this is the better way to do it.

I do have a question, is this cheap dac I'm using harming the signal in any way? You can spend big bucks on dsp's I kinda gotta assume using a cheapo dac isn't the best? Idk it sounds freaking amazing lol
[Android Head-Units] marchnz:
Let your ears be the judge.
[Android Head-Units] jchilla:
I hereby rule in favor of digital output. But definitely, it can be too easy to get caught up in "specs" of all this equipment when what really matters is what it actually sounds like to you especially. great advice

🆘 🆘 🆘

Hello guys, I need your help.

After updating to the latest firmware and MCU (clean install) the display stop outputting media info to the car's original screen. I tried to re-install the firmware and MCU and the problem still occurred.

So. . I tried to factory reset with (22558800) and then suddenly everything stop working. Steering wheel controls, screen buttons, everything! Seems like somehow the canbox version was lost but after setting it up the one was used before the problem is still there.

Any ideas how to fix it, please? I already have tried factory reset again, firmware update, mcu update etc.
[Android Head-Units] muminek1963:
See post #6149
[Android Head-Units] ulbx:
Actually it was #6152 as the screen was fine on mine. Although I have to search what else the factory reset messed up.

Hello, I ordered the S6 model and have a question about connecting the amplifier. The device has one subwoofer out, but my amplifier has two low-level inputs, RCA in L & R. How should I correctly connect them?
[Android Head-Units] refsada:
Works for someone Bluetooth Tethering? It does not work for me. Is activated on the radio and cell phone.
[Android Head-Units] jchilla:
S6 brother ditch the rca outputs and use the digital output, then to a dac, then to your amp. I just commented about how good it sounds a few posts up. The dac is cheap, only $20, you will have crystal clear audio trust me bro you will never go back. The path will be from radio digital output to dac digital input then dac L & R rca out to rca input of your amplifier. You will hear sub frequencies you've never heard before it's so clear
[Android Head-Units] cleverdicky:
Hi, does anyone happen to know any part numbers for the jst ? type connector plugs on these units plz.

Im afraid the bunch of grapes style of wiring has meant a few have broken of the pins on mine.

Is there a way to connect two devices via bluetooth? I want phonecalls from my smartphone and music from second device (tablet).

I can only connect one device, when I try to connect second one - the first one is disconnecting.

I tried to use "dual bluetooth" in factory setting, but it seems to do nothing.

Hello

..is there any code to increase brightness like junsun code 1616 has?

Or any other way to increase the brightness of the Roco K706 radio?
[Android Head-Units] mad212:
Do you power the DAC from one of the headunit USB ports?
[Android Head-Units] MauriBixio:
No
[Android Head-Units] jchilla:
Yup! It runs off 5volt so even any phone charger from the cigarette lighter would work to, but definitely most convenient to run off the USB head unit
[Android Head-Units] OneMisterios:
I have translated the firmware into Spanish language, what I could. Hizpo has said that they are going to release a new update. If you want it to be well translated into other languages, you have to talk to them. I have this file that they sent me to translate. Pressure Ossuret and Hizpo to do something. Good luck
[Android Head-Units] Peixeiro:
I want translate to Portuguese. Can you send me your Spanish translate? It's easy, because the similarity...
[Android Head-Units] stormrider57:
Hi there 😉 im new (with k706, Hizpo 8go 128 13.1 inch)

this isn't my first head unit i've already had 4 (fyt, topway, etc.) i've just updated the firmware and the MCU

I put back some applications (navradio+, power amp, etc...)

I received it yesterday, so I had a usb problem, the one that preserves the factory ones, suddenly no sound, I tried all the ports, it was too random, then I took a 4 pin connector from my joying and there the usb key was detected.

The next day, I turn on the radio, no sound, nothing, I remove the usb key, and try to read the music, which are on the hard disk delivered with it, nothing, then I restart, and there I have sound, I put back this mini usb key, sandisk, it works a few seconds, and then again no sound, I removed some files that were on it except the music, since it works, in any case I hope it was this.

I would like to point out ,that this head unit manages, my factory amplifier, and subwoofer on JEEP renegade.
[Android Head-Units] stormrider57:
has anyone used another launcher?

I suppose you cannot display the album cover with poweramp in the little native widget, it only works with the original application.!!!
[Android Head-Units] Stormbringer!:
I don't know much about the optical stuff so forgive if this is stupid. I'd like to go to a 5channel amp. So I'd like to know if the optical out has only 2 channels or 4?!?!
[Android Head-Units] redlikemethodz:
I'm having the same issue where my unit can only access the 2G band of my cellular provider. It only shows either GPRS or EDGE connection type. Were you able to resolve this?

Thanks!
[Android Head-Units] redlikemethodz:
How did you even get 4G to work? Mine only connects to my provider's 2G band.....
[Android Head-Units] OneMisterios:
Reset your radio from the screen . That smale hole.
[Android Head-Units] jchilla:
It's all good man I am too even with audio in general there is so much to learn and I'm just really getting into it but technically the digital signal output from the head unit is the complete full signal from the lowest lows to the highest highs, from 10hz-20khz something like that range. From there if you are wanting to use RCA inputs to your amp your going to have to obviously split that full digital signal into however many channels your going to use and you can do that with a DAC (digital to analogue converter) or with a DSP (digital signal processor) and there might even be other ways too but those are two that I've seen. The DAC which is what I used in the pictures above, are pretty simple and surprisingly extremely cost effective, and all they do is take that digital signal from the radio and convert it to RCA outputs L & R. Now sort of similar to you im using a 4 channel amp and to use all 4 channels I am just simply using a Y splitter to essentially double the RCA output from dac so I have 2 L & R channels. Since your using a 5 channel in kinda stumped how you'd get 5 channels out of it, I'm not sure but do triple RCA splitters exist? Lol I feel like they do, you could use 1 regular Y splitter and a triple? Y splitter to get your 5 channels? There might also be DAC that can output more than just 1 L&R and that way you could easily get 5 out of that try looking into that?

You could also go the DSP route a little more expensive but they are really amazing piece of equipment because they allow you to do pretty whatever you want to that digital signal, you can set crossovers, individual EQ's, limiters, all kinds of crazy stuff that is totally worth it. The PRV 2.4 dsp is about $70 and is a great option but there are tons of others too just throwing it out there but the DSP would easily allow you to have 5 channels out and each individual channel you can set all of its own parameters.

I am extremely happy with just using a DAC and am so blown away by how good it sounds but I am also insanely curious to what I could do with a DSP that I'm probably going to get one very soon here.

Hope that helps you plan your build better, if anyone else reading this has a lot more knowledge about this and knows of other ways I'd love to learn as well

That's no problem. Just set the GA as standard voice app and define the steering wheel key if needed.
[Android Head-Units] Clyde72:
But voice activation won't work
[Android Head-Units] blue_one:
That's correct 😉
[Android Head-Units] Clyde72:
Just had another look at running services, amongst them is "TXZ" and some further searching confirms me that Google Assistant indeed conflicts with TXZ Speech.

So there are 2 options for Assistance with voice activation: to Toppal or not to Toppal.

I have issues with my S4 4gb from hipzo with this soc.

- 4g no work no detect SIM card

- Display and memory FM. When car is a longer time off (maybe 8+hours) i on ignition and Android HU and i see this damage display, radio is restart (no memory FM station). Display work ok after 1-5 min.

I have sleep mode on. When i on ignition (example 1/2hourse) Android HU on very fast, display is ok and memory station work.

I think maybe display is damage, but why memory station are cleaning?

I noticed strange thing. Ignition is on and radio on and display work fine, when i off and on ignition or double click button power display correctly off and on. Service work ok. When i use button restart (in this small hole), HU od off and on with effect how on foto and memory FM is lost.

Do you any idea? Thanks
[Android Head-Units] Ccleaner63:
there's a sleep whitelist in the factory settings menu that prevents apps from being killed in standby mode (ignition off).
[Android Head-Units] popamor:
But the FM stations should be saved through restarts, reboots and so on. My S5 saves that stuff across shutdown and reboots. Reset is a different story as it resets back to defaults. What firmware version are you using?
[Android Head-Units] Meteordust:
Hi,

My device has weird problem with time, my time in status bar was running 4 minutes behind, what I can see is that network time is getting overruled by GPS time.

When I put that switch off/on (automatic network and GPS time) in date/time settings it first showed the right time and few seconds later overruled by GPS, 4 minutes behind.

Time showed in GPS app was 4 minutes behind, did a "clear and update" in the GPS app, it updated the time to the correct time and status bar time also changed by that, so assume this GPS app is responsible for the GPS time in the status bar....so hopefully it fixed the problem, but don't understand GPS didn't showed the right time in the first place? or starts to run behind after a few days..?

Incorrect time/date can give Google Playstore problems, or other app problems I assume..not when it's a few minutes of, but when it is totally out of date.

Noticed that date/time during start of the unit is way off, needs to be updated by network time/GPS, so time getting updated few seconds after homescreen comes up after a start. Unit connects to phone hotspot.

Maybe I need to check what my date and time is doing in sleeping mode, before I had problems with Google related apps, Playstore, Youtube and other apps I installed from Playstore when using sleeping mode, they where not opening or CTD after unit coming out of sleepmode condition.

Btw have sleeping mode off now and that problems disappeared, also whitelisted all possible showed apps.

Anyone has/had same issues..? my device s7, fw 20230109, mcu 20230103.
[Android Head-Units] Clyde72:
My unit is connected directly to 12V and shuts fully on and off. It shows the fw release time and date when just booted and then also gives correct time & date after some seconds. Was working ok when connected with canbus and sleep mode off. It doesn't cause apps malfunctioning or so it doesn't bother me much.
[Android Head-Units] Meteordust:
That was not the question, also explained that sleepmode gives problems and have it off, and yes my unit also has 12v continuous and ignition key startup the unit.

Question is that it seems that time on homescreen/ status bar gets the GPS time, yes after a few seconds, but it was 4 minutes off, clear and update in that GPS test app corrected my time, so GPS test app showed also 4 minutes off before clear/update AGPS and after that both where correct.

My conclusion was that the GPS test app provided the time, but not sure what is underlaying in Android itself, not an Adrroid programmer myself and GPS test app cleared something in Android system, regarding location and time settings.

Maybe someone, had the same issue, not asking for who has not with all respect.

No other setting also possible in time/date settings, like only network time and no GPS, GPS seems to overrules network time possibility, just hope that time stays correct now and maybe someone had a solution to prevent this in the future.
[Android Head-Units] Clyde72:
I just wanted to say that it maybe doesn't have to do with sleep mode. Just checked it and is 2 min off on my unit. Yup GPS time.

Network time and date setting have never worked. Tested it beginning december. Then I still was on canbus and time and date were always correct as it synchronised with the car's time and date via the car canbus network I guess. Connecting to internet never made a difference.

I'm no programmer neither but I know there is no way to reprogram anything if you cannot get into root (or in engeneering mode at least). Those with programming experience are trying to get into root or engeneering mode since beginning december when thread was started... and since I've joined the thread and follow it daily.
[Android Head-Units] xdomino996:
No radio app on whitelist

I have firmware on photo
[Android Head-Units] Clyde72:
You are still on 0818 firmware & mcu, you would better do some updating, it will solve FM issues a.o. Be sure to pick files for S1-S4 untis & tick the option to keep your user data before updating.

I´ve tried out the onboard ARM USB test points today. Windows recognised a new device but couldn´t activate it. I guess the right driver is missing. Had not much time to play around...

Thanks! I should choose newer soft? Hizpo Android HU isn't FYT? I have model for Opel Vivaro. Thanks :)

Should not that help with issue display?
[Android Head-Units] Clyde72:
Not sure if it isn't FYT, to be sure check with HWinfo app and compare with the chart in first post before trying updating anything!

With us, system info screen looks different...

Or ask your seller directly for firmware update. Much safer.
[Android Head-Units] popamor:
I would suggest you upgrade your firmware and MCU to at least the November version. That one helped a bunch of issues. Make a list of your issues before upgrading. Then test out your issues after upgrade to see which ones are left.

Found a way to access engineer mode..

1.Download from google play.

Shortcut master (lite)

2.press 3 dots on upper right and select "secret code explorer"

3.select engineer mode and press explore.

4. Select a sub menu that says engineer and launch!!

Superb, maybe we can adjust mic now a.o.

that makes sense, the 5th channel is just the subs, I can grab that elsewhere. I'll look for one of these DSPs or DAC that has 4 channels. I really want fade, etc..

Jst 2.54mm connectors, id recommend getting a kit with an assortment of sizes they're well worth it for like 15-20 bucks
[Android Head-Units] cleverdicky:
Thank you. I soldered what I needed directly to the board now.

I looked at the kits even cheaper here UK. but wasnt sure of the spacing size.

Or is that the pin size. It looked about 1mm to me.

Way to small for the cable sizes.

Also I couldnt find a kit that had any 20 pin (way ?) plugs .

There is a code (four letters) stamped on the side of the original plug which I did search but found nothing.

help with the problem. I downloaded the updates, installed the update from a USB flash drive. And now the side buttons (touch buttons that light up) don't work for me and half of the programs don't work, namely, I can't go into the settings.

The mp3 files can be assigned album covers (you can do it yourself with the appropriate program) and then they are displayed during playback. At least that's how it is with me.

Just wondering how many here were px5 owners ?

Do you find these radios K706 are better or worse ?

I know they are cheaply made units even with top hardware specs (if selected). And im gradually working through some issues before I get round to fitting mine. But I cant help but wonder how much better they could be, as was the case with the px5's, if if say Hal9k were to do a complete custom rom for them.

Wonder if he's around doing roms still or fighting pootins war ?

Removing those sample files does not rewmove that picture, it must be stored somewhere else unfortunately.
[Android Head-Units] Mr.TT_NZ:
From what I can measure the hardware is not too bad but the software seriously lets these units down.

This being the 'Android developers' forum' I had real hopes that some of the developers here could fix those problems; so far I'm disappointed as none of them seem to visit this part of the forum or won't contribute.

A full custom ROM would be great, we could all add our input to ensure that all the bugs were eliminated right at the development stage.

Should a developer here work on a personalized ROM, waste so much time, that they would then use the Chinese to sell it with their units, without making any effort and earning free money?
