Bonroad Intel Sofia HU - MTCD Android Head Units General

Hey guys anyone have a photo of how the wifi antenna is soldered to the board, ? rookie mistake & forgot to snap one before I desoldered it to get some new thermal paste on the cpu & install a new fan.
Cheers !

Microphone problem...

Hello there,
I have a big problem with my desire hd , my microphone stopped working , so i tryed to unsolder it and solder new , but in the process i wiped the 4 pins underneath the microphone , so I'm asking if somebody had schematics for this phone so I can trace wire path of the microphone and try to solder it there.
Also i read over the net for the method of change deffective mic with new universal mic and 4.7kO resistor , but there weren't any more explainations, so if somebody knows and wants to share info will be glad and thankful.
10x in advance.

5ghz

Hello XDA,
As most people know the mtk6753 support 5ghz. But the hardware in the p8000 isn't there. But if i am right our phone is just missing an antenna. Is there a way to add this antenna with a piece of metal?
jiayu s3 antenna
Hello guys,
After some research i found out that maby it is possible to replace or wifi antenna cable with the jiayu s3 antenna cable.
Is there anyone out here who can already tell me that this will not work? http://www.aliexpress.com/store/pro...-mast/1016211_1949602463.html?storeId=1016211

Joying MTCB HU, USB connections.

Just installed a Joying:
. SKU: JY-UL124 . Quad Core Android 5.1.1 Lollipop OS Capacitive 7" High Definition for Universal Double Din . CPU: RK3188 1.6GHz Cortex A9 Quad Core, Resolution 1024*600. RAM:DDR3 1G, 16 GB memory
To my 2014 Australian Hyundai Elantra.
I waited to get the latest HU from Joying that has an unrated mother board and USB/ Comms board. With Lollipop 5.1.1. the unit performs very well with none of the problem previously mentioned on these pages. The internal and external mics are clear and the Bluetooth systems are perfect. Unit has been rooted and I don't seem to need for apps so I won't changed the software.
The dimming for the button and the screen to follow the vehicles rheostat was fixed by making a circuit to invert and amplify the rheostat output to the HU ill line. Work's well, Kudos to the guys at the Subaru forums.
I had one bug fixed by Joying when the GPS nav was muted whenever I plugged in the DVR front camera. Joying quickly sent me a link to re flash my firmware and the problem was fixed. I have them currently looking into a bug when I view the DVR input shown on the HU I get lots of flashing to the screen in all pixel settings. I have been told this will be fixed in the next firmware update soon.
One problem that I can't solve is when I try to use my vehicles Multimedia Jack located in my center console. There is a Aux and USB jack there. All wiring from console to HU is complete. If I connect a USB stick to the Jack in the console then then HU struggles to connect and gives up. If I interrupt the USB plug and socket behind the HU then I am able to use the USB correctly. Looking at the car wiring diagrams there is a amplifier cct behind the Multimedia Jack supposedly to amp up the USB to HU. Doesn't seem to work?
Any ideas appreciated.
Duke
If anyone has any ideas on
i have nothing to add, other than interested to see what the result is. Are you saying that your car comes with a built in hub in the console, and you are trying to make that USB port in the console work to the Joying head unit? my vehicle is similar, and I would like that to work as well
Update
Yes I have a console hub I guess.
The book calls it a multimedia center. Just an Aux port and a USB port or Jack in the tidy bin in the center console. If I by pass the Jacks and directly put the USB stick into the USB tail from the radio then it works fine. When I plug into the console port it tries to read it and fails. The HU then reports a read fail, have tried other known working USB sticks.
I have inspected behind the console jacks and found a cct board attached to the Jacks and then to the car wiring. From looking at the diagrams of the car previous to mine I see a cct board containing what looks like an amplifier. Tracing the car wiring to the radio input connectors seems to be OK and the wiring correct. Voltages at the radio connector are right in that there is 5v +ve, negative - earth and the center pins are data as they should be.
The console Jacks

The wiring for same (mine is same but more complex)
w.hemanual.org/multimedia_jack_schematic_diagrams-2036.html
Really bugs me not to be able to access that USB input Jack esp as the radio is a great unit.
You need to post this question in the MTCD (Lollipop) hardware thread. This thread is for MTCB (KitKat) units. The hardware in the MTCD headunits are very different than the MTCB headunits.

Yes, the MTCD thread is for the headunits with 5.1.1. The hardware changes and software are different. Send one of the admin a message and tell the why you need to get the permissions to post. I had to do that some time ago. Just make sure you follow the rules when post or you can have you account suspended or whatever the moderators deem necessary.

Ok thanks for that. I don't seem to be able to find how to "Send one of the admin a message" Can you help?
Just for info, there are both MTCB/C and MTCD/E Lollipop units.

Anyone with a dead px3 who can locate the SPDIF pin? (Expose the Balls)

Hi, I recently installed an MTCD px3 unit in my car but the audio quality is not that great. I'm looking at the option of a USB DAC but that appears to have its own set of issues and complexity.
I do note though that the RK3188 chip includes an SPDIF function and this does appear as an audio device in /proc/asound/cards so if the pins (balls) are exposed somewhere on the px3 module board then it should be just a matter of soldering to the right points to create an SPDIF interface.
If someone has a totally bricked unit would you consider doing some research? I.e. using some heat to the remove the RK3188 BGA chip and locating the ball that relates to SPDIF and seeing if it can be traced to a track?
The SPDIF transmitter is located at ball N20. You can find the datasheet by googling "RK3188 Datasheet" (sorry I can't post links yet). So who can "expose the balls"?
Alternatively if someone has a dead board/unit they would give away, I'd be happy to pay shipping for you to send it to me (in New Zealand) and I'll do the research and share my findings with the community.
Also looking for someone who understands what would be required on the software side of things to actually use the interface. Some kind of ALSA magic I guess?
Note - I do understand the limitation. I.e. this only applies to audio within Android, not the radio or bluetooth etc. My approach would be to install a physical switch so I could switch my car amp between the analog and digital outputs.

Interesting, those are MTCD/E units, I ll get this thread moved to the MTCD forum.
They claim the resolution is 1240x1080 in those listings.
i don't тhink so, always 1024*600 is mentionned on theese product :/

Its mentioned in the spec sheet but in the pictures it says 1240x1080, the only way to be sure is to buy one I guess - they previously claimed that 1024x600 was HD but its isnt.
None of those items are available.
I have asked for the resolution of these PX6 model
Like: https://ljd.en.alibaba.com/product/...T.html?spm=a2700.7803241/c.0.0.4c8e3e5fwpqDt3
And 1920x1640 is not the resolution of the display. The display is still the stupid 1024x600 resolution. The device have the same stupid 10 years old video output RCA connector, USB 2.0, ....
I will wait some hardware upgrade not only CPU... in next 10 years !!! stupid !

I think youll be waiting for some time.
1024x600 is perfectly good even if it is a weird resolution.
Some RK3188/PX3 Lollipop units have HDMI out if thats important to you.

You are right;
- I know I will wait for a long time, and it is a shame because these Android radio are great …
- resolution, USB2, RCA can be enought, but it is 10 years old , and we want better like our phone, tablet, TV ….etc..
(RK3188/PX3 doesn't work correctly: perf, same display, USB2.... and I don't know why they didn't keep HDMI with PX6 because the CPU have HDMI output...)
I only want to say that these products could be very very very exceptionnal if not only the CPU was upgraded…
I do remember a few HDMI-out units, but most manufacturers seemed to have switched back to RCA video out. Honestly, the reason is probably becuase there is not much in-car gear with HDMI. I mean my headrest monitors are RCA-based, my backup camera is RCA-based and dashcams are usually USB or RCA-based.
What would you really use the HDMI out for?
I *do* wish that the audio-related internals and screens were better quality though (not really higher resolution, just higher-quality display types - no more TN displays). I also with they had anti-glare coatings. A super-reflective screen in the car is just a bad idea... And the CANBUS interfaces that generate sounds are just ridiculously bad. The turn-signal and warning chimes that my CANBUS module generates are laughable...
- "A super-reflective screen in the car is just a bad idea... " => Yes , it is so so true !¨"
- I understand than RCA is usefull too, but they can provide RCA and HDMI (like old PX3), it is not complex (hdmi pin is present on PX6) .
(I need HDMI for my HUD and at this time, I must connect it by USB + displaylink vdeo outut card which it use CPU. The resolution is not very good because the display resolution of the unit is low. (when I use MHL of my tablet, the result for my HUD is "perfect").
- and I need USB high speed for my phone, harddrive….
Unfortunately terrible glare is common even on new cars. Look at tesla that everyone is copying. Very rare to see cars with anti glare screens. Surprisingly more common on cheaper new cars.
I like there is innovated MTC revision after so long, but I will cowardly wait until there are some in stock in EU and first reviews by others come in
I've had 3 or 4 different aftermarket WinCE-based touch-screen 2DIN units in my GM and they all had anti-glare screens. It seems that when manufacturers switched from resistive-based touchscreens to capacitive-based touchscreens, they also lost the anti-glare coating. Eonon actually includes an anti-glare screen protector when you buy from them (at least some of them), which is nice, but unfortunately, they leave a small gap around the edge of the screen since they are a little smaller than the screen itself. For the life of me, I can't underatand why anyone would want such a reflective screen in the car... The nicest screen in the world doesn't do a damn bit of good if you can't see it. The anti-glare layer also significantly reduces fingerprints.
I have same grime with today's TVs even, no way around it. I'm accepting need for protector.
I'm new to all these head units, but from the looks of it, it is all the same with different face plate only - ie. touch buttons/volume rotary knob.
I will wait for px6 64gb in eu and finally give a try even if noone post review here or on 4pda
I mostly want it only for reversing camera though, but still Chinese android HU seems most reasonable, sad
I think those sellers are exaggerating about the maximum core speed.
There are 2 models on the marked, the A72 2.0 GHZ is the RK3399 PRO and the regular RK3399 A72 that run on 1.8 GHZ
http://www.rock-chips.com/a/en/products/RK33_Series/2018/0130/874.html
http://www.rock-chips.com/a/en/products/RK33_Series/2016/0419/758.html
Also these chips get seriously hot, so these chips realy needs a heatsink or a fan, not a simple coverplate like now on the px5.

Why would you assume that theyre "exaggerating about the maximum core speed" ? The RK3399 is available with 2Ghz so we ll assume that these RK3399 units use the RK3399Pro. If someone buys one and the max speed turns out to be 1.8Ghz then we ll know its a plain old RK3399.

How many sellers claimed that they selling a RK3188 @ 1.6 GHZ while they selling the much slower px3 RK3188-T that runs 1.4 GHZ. even the gpu is slower than the original RK3188. So it would be not the first time that sellers exaggerating.

Not that many.
We best wait for someone to get hold of a unit before judging . . .
We all know they'll put a new coreboard on the same motherboards and sell it as the next big thing.
Nothing else will change because the motherboards don't change and that's where all the other functions are.
The only change is this one will get hotter even faster since they won't dare put a fan or proper heatsink on them.

As I said, best to wait and see rather than speculate. Oh and the motherboards do sometimes change and some manufacturers do fit fans.
Would PX5 firmware run on these PX6 Units? Does it need to be recooked?
I have one live PX6 head unit.
Thanks
