[General Discussion] QF001 (ROCO K706) Head Units with UIS 7862s (not FYT based) [read first post first]

[ImBenny]

Carletter works on both, wireless and wired on S5.

It starts sharing WiFi on wireless mode, isn't it?
Mine does nothing.
My phone even crashes after waiting a lot.

 

[ImBenny]

thank you, I will try when i am at home!

Unfortunately, my wireless android car does not work either. It randomly stopped working on the 0414 update. That's why I updated to the 08/05 version, that didn't solve the problem either. And even after a factory reset I can't get it to work..

Maybe we should try out downgrading the Android Auto App on our phone then.
What if it stopped working after a Google Play Store update?

 

[noppoer2]

I don't think it's an issue on the phone. Normally, with carletter, the Bluetooth logo turns green when my phone has a Bluetooth connection with the unit. That is not happening at all now. The strange thing is that apple carplay wireless just works properly.

Didn’t worked for me.. I’ve downgraded to the same version but still overheating.. what is the normal temperature of the unit ? I mean when listening to radio or using CarPlay ?

If fixed in car, i had 55-65, but in last tuesday i did some mod and

Next change i made. I have glovebox with wentilation (if the ac is working then i have cool air in there) so i connected air tubes and guide one to the back of HU, near the fan. Also i change a air direction, to fan blow inside HU. First tests look good obviously. Before this change, the HU fan blowed constantly and normal thing was 55-65 degree in CPU (condiotions: radio and google maps was on, nothing else, outside temp 22-23 C, AC off, car fan on, on the lowest speed, inside temp was set to 20C). Now there is ca. 42-46 C in the same conditions.

Anyway. Go to Factory and set "332211" it should be a popup with cpu load and temp (you turn off the window by write again this code) . If the load do not change in time, but it's in max, then there is something wrong with MCU firmware or in mcu itself. But if the load change between min and max, i suspect no thermopad between cpu and housing. Somewhere in the middle of this thread, there is a description how it looks

Remove bluetooth pairing on HU and android auto history from phone, then retry. Else factory restore the head unit, and try again.

 

[noppoer2]

You have to remap buttons in the settings!
Go to settings, enter 8888 then you will find a menu there where you can add functions to buttons.
I am working now but I will take pictures when I arrive home if you want.

Did you get the Wireless AA work btw?
It worked well to me before the update but now it only works wired via CarLetter.

Yes it works again now!. vias the menu of 8888. I have set all the buttons. Thank you!

I have followed the steps above with no success. Even a factory reset didn't help. When I have time, I'll investigate why it will come. Otherwise I will look for another app/solution

Thanks i'll try that before modding anything !

Has anyone pulled the Audio player stock app from the Sx model radio?
Horrible look, I would like to see if it is possible to "modify"...

What can be a valid alternative app to this stock audio player, in anticipation of using Car Launcher Pro as main launcher?

 

[Clandaries]

Maybe Musicolet. It also has car mode.

Edit: i was thinking of radioplayer. That one has a car mode.

But Musicolet is a good music player

Thanks.
I know Musicolet good app.
I tried this app on Car Launcher pro (only test for the moment with phone, I want to create my theme first...) and it works fine embedded, in background.

With phone, however, when it connects with Car Launcher, an popup appears at the beginning (if I have the data internet active) then immediately after the popup disappears.

No other free and ad-free player, which works totally embedded, in the background (even at the beginning) with Car Laucher pro?

edit:
I'm talking about audio player app that can work mainly offline ..like Musicolet.

Hi all, if anybody would like to test a very early alpha version of NavRadio(basic), they can find it here:
Download NavRadio BASIC for QF01

it's incomplete, full of bugs, it surely crash here and there but still usable.
I have enabled Google Crashlytics to help me debug all the crash and ANR so more people use it and more i'll fix it.

The full version will come when the free version will run smootly.
Enjoy


NOTES:

- Autoscan is done by MCU and it's fixed to 18 stations. Anyway you can use Autoseek function to find more stations or add new ones to the existing ones.
- The first frequency at startup need to be fixed.
- Sometimes you can hear the sound muting for a second, it's because the ROCO service think that navradio is a player and not a radio. I'll look for a fix later on..

Good thing is, it's work on ours HU
As a as a beta tester, first impressions:
1. As you notice, it stop playing randomly, and as for me it stop completely, there is nothing i can do but change a station or reload the app. For now it's a main problem.
2. equalizer button, not work
3. the app is in the same volume level as oem app, and for me they both are to quiet. I have hope to get a volume control in this app (it can be done in app like musicolet, so it isn't impossible, i gues)
4. I have notice, that in oem radio app via canbus shows a station frequency preview on instrument cluster (see the video). Is there a way to do the same here?
5. On instrument cluster station preview i've notice also, that radio app volume shows 1 step lower compared to global volume, eg. if on instruments i see volume 2, in the same time on HU displays volume bar in level 3. Maybe it have something to do with point 3 as above.
6. In full screen the app shows 6 remembered stations (quick selection). Now, if i use a split screen, the app shows 4 buttons, and it's ok. But, if i go back to full screen, then i see only 4 buttons instead 6. See seccond video.

Hi There
this happened to me when android auto went from 9.4 to 9.5. After several unsuccessful attempts, because after a few successful connections everything failed again (the bluettooth was connected but the carletter did not detect it), it was only possible to connect via cable. I downgraded the firmware because before everything worked, and guess what?. Anything !!. Then I remembered the several years I spent on the MALAYSK forum and had an epiphany. Never upgrade or downgrade without erasing all data (user included). I know it's really annoying but it has to be (tick checksum and user data). One of the things that alerted me was that without deleting everything, when you change the launcher it duplicates the apps in the application drawer. So now whenever I upgrade or downgrade I delete everything. If you notice the time of the first boot of the device after updating is longer. Now everything works like before including (hey google), which only worked with the wake-up button. Try this because it could very well be the solution to your problem, which was mine too. PEACE

Today just installed a new Hizpo S3 in my wifes car, this is a Qf001 / Qf003 version. This is a lot faster than a older S4 Qf001 version.
Canbus Ac working, other features like hybrid car monitor and keylesgo ( smartkey) are working. Sound is a bit better.

Great news.
With this new HU,
Firmware version?
MCU version?

Can you inquire if MCU QF03 also works with "old" HU Sx and current QF01 MCU latest release?

And...AC works,brand car\model?
Canbus HU hardware: type\name\model?

Didnt tested too much, but I will use it primary in next days.
1. For short time didnt noticed stop in playing.
2. Equalizer button, not work
3.Volume level is good for me.
4. Can bus work for me as on stock app, but it would be better to display station name instead frequency.
5. I have similar problem as marioti described for resizing window.
6. I noticed steering wheel button for changing stations not work.
Anyway thank you very much for this project.

I did not updated it, because anything works just great for now..
It is installed in Toyota Prius Plus xw40 2012

Thanks for your report
Please specify your model, MCU and radio type

1. ok, noted down.
2. I still have to work it
3. ok, noted down.
4. i still have to look at the entire canbus, that will be my last priority
5. NavRadio is not considered a radio app but just a third party app so that could be the reason
6. I'll look at it

So I did the 332211 code and yes the cpu is fluctuating from 600mhz to 1800mhz that means I have to open the unit to see if there’s no thermopad and put it one if needed

I’ll keep this updated thanks

1. ok, test it more so you can report me better
2. I still have to work it
3. ok, good
4. i still have to look at the entire canbus, that will be my last priority but i doubt i can display text...
5. I'll look at it
6. I still have to work on SWC

I can see that your unit show the RDS text and this is great because i could not test it on my unit

Hizpo S8, MCU is latest 230207 (https://jitu321077708mcu230207.oss-cn-hangzhou.aliyuncs.com/mcu.bin), radio is TDA7708.
As of No 4., stock audi radio BNS 5.0 was displaying station name but this unit displaying only frequency in radio. But if I open phone, it displays "PHONE" so its capable of displaying text.
