Review

Hi. I'm from Brazil.

My review about my hu threecar Stm32 px6 9" IPS 64Gb DSP version.

I'm using MCU mcu-202007211001KC6-1414, firmware Malay full v2.2 DSP version.

I really recommend to change the capacitor 25v 3300mkf to a 10.000mkf. The difference in mid-range and low frequency is impressive!

I also did an upgrade to cooling the processor, with passive heatsink, which is enough for the px6 dissipation.

Everything is running smoothly. I'm satisfied with it.

Some pictures attached
[Android Head-Units] khldacosta:
Thanks for the hint, I've ordered a couple of replacements! Do you know if the capacitor just filters the input power? Any audio quality issues, popping, white noise etc?
[Android Head-Units] megatm:
No audio issues. The mid-range is more evident and the bass more deep. Before the capacitor change, I had a pop-up sound when turning on the hu. After that, it's gone. I tested the frequencies using AudioTool from play store with Dayton iMM-6 Calibrated Measurement Microphone, and the frequencies improved considerably.
[Android Head-Units] khldacosta:
Thank you! Many people just think it's "better" but you have proven it! I will sadly not know if it is better as I will be upgrading capacitor without testing fully first.

Recently realized that GPS cannot find any satellite. It used to locate 7-12 satellites but now can find only 1. The unit is PX6 STM32 DSP from EUNAVI. Is there a workaround to locate the issue?
[Android Head-Units] InstandRadio:
I have a DSP radio, but one that fits into my Ford Focus MK2. It's a PX6 with STM32 MCU. Can I install this update?

I am currently having problems with my radio. It keeps crashing and that annoys me a bit. The support, well it's not much help now, I have to admit and have a few other bugs that I noticed. I hope you can answer me :)

does it look like this?

Thanks for this lively discussion, it made my day!
[Android Head-Units] InstandRadio:
I dared to install the Android version of Threecar on my "look a like" Ford Focus MK2 / Mondeo MK4 radio. Unfortunately there are only very short and concise answers that make it difficult for a newcomer to know what to look out for. In any case, it's going great. Up until now there have been no more crashes and the navigation voices are output correctly at the correct volume. What surprised me was that the buttons on the radio don't have to be reconfigured. I suppose because this information is stored in the MCU. Many thanks to the person who made the software available here. I would have liked to have taken the mod, but again no information about the difference between the Lite and the FULL version, no answer to questions either.

[Android Head-Units] InstandRadio:
I wasn't sure about the support in the forum and decided against the mod. I installed the software from Threecar, which works really well and is very stable. At least for me. I think there is a fix for the problems with the rear view camera. Have you tried that It's a few posts further under the download link.

I'm using Threecar's firmware. It works very well. Unfortunately, I don't get enough information about the difference between the lite version and the full version.

Here is my OS and mcu.

My maker told me. Different batch of px6 with stm32 using different OS AND MCU. cannot mix..

I had serious doubt on it, as long its px6 with stm32, it should be all the same OS and mcu.

You have no idea how much i waited for this link...

Guys, I want to share my problem I have with my eunavi PX6 STM32 HU.

I bought it on AE from a factory they had (eunavi) in Poland. The HU came quite in good packaging, and after installing, one day later the HU started showing some strange signs.

It would randomly reboot, sometimes playing the radio it freezes and restarts radio app. Sometimes it freezes the screen, the touch doesn't work but the radio keeps playing. Most of the time it happens the screen freezes and it goes out rebooting.

Most of the time after 5 or more reboots, it kind of starts working fine. No reboots for all the ride I do with my car. USB/Radio/Video everything works fine. When i leave the car siting for 3-4 hours or next day same thing happens.

I tried almost every rom and MCU i could find...from 2019 to 2020 with no avail (except this december 2020 firmware that you just posted). I can also send you the links of all the firmwares I have gathered, could be useful (including IMG files for creating repair sd-card)

Do you have any idea to what causes this? It is strange that everytime i update to another firmware it works ok, until i turn of the car, come the other day and freeze/reboot stars again. I also did a fan mod which i linked it to one of the external USB that the unit had.

Is it possible this USB does the problem? Also i remember whit one rom whenever i put my phone usb it rebooted...

The only thing left to do is:

1. Check the back connection...I am pretty sure that everything is fine, but just to be sure, maybe re soldier the cable pins...just in case

2. remove the speaker connector (maybe one of the speakers causes shortage, two of them have their round cone broken)

3. Remove the antenna cable, maybe it has a problem...it has been raining all these days, maybe it is connected...

4. Remove the fan that os over the CPU...something strange that when i was modding it, applying a small presure on the top of it caused reboot... (at least happened once)

5. Last but not least, the only solution if it is not hardware related, I should test it in another car. It is strange that when i was updating it I hooked it to a 12 volt 1amp adapter...It never rebooted, but It is hard to believe as i couldn't connect it to external speakers, nor leave it there to test for a long time (which probably I should...)

I waited so long for this HU to come and install it in my car, and it wasn't even cheap (250$). I feel so frustrated something like this is happening. I also cant sent it back as I don't think the seller will refund due to warranty seal break (fan mod).

If you guys have any idea I would be so grateful. Thanks in advance!

[Android Head-Units] BOOMER SCOTT ROBERTS:
Need Assistance with replacing bootanimation.zip file on MCU STM32 HU!!

Hi. I hope some can provide feedback regarding an issue I'm having using a custom bootanimation file. I've tried all of the Ford bootanimations from the BOOT ANIMATION thread here which I saved to a USB drive last year to use on an XTRONS which, I believe, is a MTCx type HU without any issues. Any of the FORD animations work on my XTRONS HU.

However, after uploading any of those same animations to the new Eincar HU and rebooting (and after the boot logo I chose from the available logo files) the animation doesn't play. Instead the display is void during the time the bootanimation would normally display. If I remove the file from /system/media then I see a generic ANDROID animation. This particular animation has to be built into the the OS someway because I can not find it anywhere in the HU. If I upload the bootanimations (800 & 124) that came installed on the Eincar HU, they display. I've read through posts in this tread as well as the BOOT ANIMATION thread but can not get any of the custom bootanimations to display, or find a resolution to my problem. I'm stumped!

Suggestions are greatly appreciated.

[Android Head-Units] Meteor100:
I would like to share my solution for improve cooling. I've used aluminium radiator, PWM controlled fan (from old graphic card) and Attiny13 microcontroller to control fan speed (according to radiator heat).Fan starts when temperature raises over 50*C. I've tested the radio in 20*C and fan starts once (for 2 seconds) every 1 minute (during benchmark is working) so i think that in hotter days everythink will be work great.

Hi there guys.

I need help if it's possible.

I bought recently Bosion PX6 4G +64GB NODSP version for Audi A4.

I have:

KC1E0112-PA1-1.1.4.3.1 - BLINK161 - 20191129 - 701F

STM32-20191028-11-KC6-41

The biggest thing is that I have two slots for microsd card in the front of the unit.

First should be for maps, second for TF card. I think they switched ports because in TF card port microsd wants to format (but even when I click format it stops at 20% and after couple of minutes it shows that card is ready - but it's not, I cant see it in ES explorer).

Other port (map) check cards when I plugged her in, but says no music files (but card is almost full, visible under PC) even ES explorer or poweramp or total commander can't see device (even in Android settings under memory), tried with two SD cards 1GB ad 2GB formatted to FAT32 (both are visible under PC).

USB port connected to the back of the unit is working fine. USB stick is detected and starts playing music immediatelly.

User @Shrinker64 (https://xdaforums.com/t/rockchip-px6-with-mcu-stm32.3976665/post-83002127)

wrote that he has newer firmware but never upload it. Maybe some one has it?

The most important thing is playing music from SD card.

Help much appreciated.

[Android Head-Units] khldacosta:
If the EUNAVI is anything like the Threecar, then as you've already opened the unit, unplug the small white FPC flat cable coming from the headunit.If not seated properly, it can cause all sorts of issues :)
[Android Head-Units] khldacosta:
This is my cooling solution. Nice and simple, big heatsink on top but differently to everyone else - I used a 5mm thermal gap filler on the bottom of the board. The CPU is soldered directly onto the board.

You can cool the processor by drawing heat through the PCB and then into the case to dissipate. No thermal shutdowns when running over 1 hour with heater on :)

Black capacitor is a mod as indicated by another user on page 20.

Uniquely, I also extend the FPC ribbon connectors if you need to remote mount the headunit as shown, there was no space behind the screen in my car. The copper is to shield from EMI ( max length around 40 cm)

My thoughts : Excellent sound quality, unit is really fast, steering wheel controls work perfectly, can run multiple apps. Would recommend to others.
[Android Head-Units] atthila8:
can this update works for me? no dsp version. thanks
[Android Head-Units] ardi_sulo:
Well, I opened the HU again, removed the two white flex cables and the brown little one. When I removed the big white flex cable, the screen greyed out the same way it does during a reboot process that usually happened... I re-seated the flex cable, and it's been 3 days I tested it, and no reboot, nothing :eek:. I can't believe my eyes :oops:

I can't believe myself I couldn't figure it out. You are e legend bro! You are a savior!

I was very desperate because the unit kept rebooting for no reason at all...

Now I can enjoy the HU as I should!

Many thanks!!! Much appreciated!

Hello guys,

I recently purchased a Bosion Px6 that came with the OS Version KC1E0113-PA1-1.4.4.1-BLINK161 20200604-N3 and with the MCU version STM32-20200403-11-KC6-37.

Meanwhile I flashed one from Malaysk and the radio is just bugs.

I would like to go back to the original version.

Can anyone help ??

Thanks.
[Android Head-Units] khldacosta:
Glad to hear it is fixed! I found out the hard way when using FOUR of those flex cables to join the headunit to the screen using TWO extenders (so 8 flex connectors to plug in perfectly.... haha!!). If ribbons are not seated correctly, even if it looks correct, it can cause:

No touchscreen.

Random reboots.

Mirrored display (left to right).

Fuzzy display.

No display.

Anyone encountered this problem.

The screen keep flashing/ flickering.

I factory reset it, but it still flickering.

I did not install any new app.

Pls help.
[Android Head-Units] Robbo69:
I would like to know this too, although a 5Hz rate may be better as there are apparently some data transfer problems at 10Hz.

There is a (paid) app called U-droid Center for U-blox on Google Play that looks like it could be used to do this but interfacing it with the head unit looked a bit complicated for me! It also doesn't look as though you could auto-start it with the parameters needed, so you would have to run it manually each startup.

Has anyone tried this app?
[Android Head-Units] trulu:
anyone here using ahd parking camera? how do i know if my headunit support ahd camera?
[Android Head-Units] trulu:
you should post a video of your screen flickering/ flashing. and check your white flexing cable if it connect properly or not. my doubt for now is from the hardware.
[Android Head-Units] Robbo69:
Not all head units support AHD. To check, go into Settings - Video and scroll down. If there is a setting Backcamera Video Input you will have a choice of several AHD types. If this setting is not there then AHD is not supported.

CURRENT MCU

STM32-20200721-11-KC6-40

I have a problem that when answering a call from the HU i have to wait 3-4 seconds before i can hear the caller from the HU (bt phone application slow to open?)

Sometimes answering a call from the connected phone, phone application in HU is not waking up so call is answered but no sound from HU. have to manually change sound from phone to phone or speaker and then back to HU and then the sound works.

Tried different phones but same result.

asked eunavi for an update and they told me to wait.

I don't know where you are getting the 403 error. I'm guessing If you are getting it while using the update maybe there is a serial check on the server to see if the unit can download the update.

Hi, I've updated my Bosion RK3399 STM32 unit with the Malaysk Lite DSP version, but after it restarted the screen was only black, no logo, nothing.

- had a dump of the flash and written it back, but nothing changed (I know weird...), black screen, no boot

- tried the SD boot method with the recovery image added in the Malaysk thread, the screen only flickers, no boot

- tried to upgrade by SD, now the unit when starts the screen only flickers, no boot and not even getting in loader mode (connecting the 2 circles near the USB 4pin 1mm SH connector)

- removed the RK3399 shield to connect EMMC TP to GND so to force it to maskrom mode, but it's not entering maskrom mode, no connection on the OTG USB (before it worked, I entered in loader mode and also maskrom mode, loaded RK3399MiniLoaderAll_V1.09.bin and dumped the flash to the hdd)

- also tried EMMC CLK to GND, no maskrom mode

- USB 5v pin is not powered, 0v on it

- STM32 MCU is powered, 3.3V

- the USB OTG cable I'm using has only GND, D+, D- connected to the PC (+5V is not connected), the unit is powered by 12V as normal, before the update the cable/connection worked

Any help in getting into maskrom mode will be greatly appreciated, I'm out of ideas... :(

What is the role of the MCU? Should I get a ST programmer and flash it? (I haven't flashed it, but can it interfere in getting into maskrom mode?)

I've attached pictures with the unit when it worked and with the lite version used for update, also the points where are the EMMC TP/CLK and for getting in loader mode, the circles near the white USB connector (the pictures are from the forums, but are exactly like my unit, including the D+/D- in the 6 pin connector that in the manual are "not connected")

Post the real photo from the downside of your HU.In some hardware of the reseller Eunavi the two pin near the inside usb connector doesn't have any function(at least for me)
[Android Head-Units] unimatrix099:
Hi, I've added the photos, actually it should not work with EMMC TP to GND, for me it's not working and the other CLK pin is not actually for EMMC, it's for SPI, I will try to put both images with transparency, like in this blog post:

https://lurchi.wordpress.com/tag/rockchip/ (here with the design from this blog the EMMC CLK is on the back...)

Btw the 2 pin near the USB worked for me before I've had the issues with the update/flashing of EMMC.

Thanks.
