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.

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.

Am I still in the wrong section?

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.

How is the sound on joying 1 din android radio? And how is touchscreen?

How does it sound. Does it work good with stock speaker and does it handle pioneer or any brand speaker (up to 4) cause i can only amplifie my subwoofer in the back since the speakers are in the doors...
And i need a new radio. But i would like th have decend sound. At least that it will handle loud sound (without basse cause my subwoofer will do that)
And does anyone know if the screen can be tilted a bit? I use a mercedes w203 c180 and the dash is not flat it goes up so radio with a flip screen are aiming at my roof...
Anyway i migh br interested in one now that u can eq the sub..
And does it have 1 sub out at 2 rca speaker out or just 1 sub 1 pair of speaker (rca cable i mean).
(i mean 1 sub an 1 speaker rca are good but maybe i wanna amp my front speaker one day)
And how is the touch screen?

What is the Rockfors....an amplifier? a Subwoofer?
Did it have some RCA inputs?

Hey,
the Rockford Fosgate Systen is a complete OEM Soundsystem from Mitsubishi.
It Contains Speaker in all 4 Doors, in the Front Doors with Tweeters and in the Rear is a Subwoofer.

Did you buy your unit with Canbus decoder?
According to Dasaita, you need the canbus CB001 for models 2007-2013 and CB003 for models 2014-2017
The can bus is needed for Rockford Fosgate System to work with the headunit

You should buy harness with canbus

Ok,
but did you can change the punch of the subwoofer?

I am in a 2013 X and have a Dasaita PX3 unit. Subwoofer controls when you have the canbus box attached are not the sub bar in the Amplifier app but the far left 60hz bar.
Hope that helps.
It's like this one... But Dasaita may have it on their site Hot-Audio.

I have the same issue controlling the subwoofer on the PX6 with outlander and fosgate system. Controlling the sub with 60hz on the eq is hardly a fix as it is just lowering 60hz over all the channels . It would benefit to be able to adjust the sub volume as it seems to be louder than it should be. I am in contact with dasaita so will see what they say.

Hi
So I have a PX6 from navifly or whatever. Anyway had probs as well, went to a place called audiocity and now it works because(still cant control the sub punch but at least now it does punch) the wiring for the amp behind the radio was wrong. The amp gets its signal from the front speakers and behind the radio the driver side front speaker wiring was wrong. Its supposed to be both the same +/- but one speaker was the other way around and the signals were working against each other rather than working together. I think now you guys mby can try to find that. Now the punch was real gooooooood.
If needed I can do few pics or a video about this.
I cant control the sub that much but I can control the bass still. So it is punching good.

Hi, if it's not a strech for you I would really appreciate some details about this.
My problem is that balance does not work (if I put 100% on rear the volume goes to 0) and most annoying probleme is that I have a bass delay, which means that when the bass should kick in it actually fades in from 0 to whatever...and it takes like 5 seconds to be at the volume it's supposed to be. This i annoying because it does not only happen at the start of the song, but also on the entire track. From factory settings I chose the sound option without amplifier because the other two options (with amplifier and auto detect) don't care about amplifier settings after restart, so choosing a customized present (or rock, classical etc) does not make any sound changes. Any ideas?

Android unit for Ford Fiesta mk7

Hello everyone,
I would like to install an android car radio in my 2012 fiesta, not so much for having the color display, the touchscreen or the possibility of seeing videos but to change the main unit and have better sound (I have installed quality speakers, I have soundproofed the doors and installed an amplifier, but there is a background noise, which also increases with the engine revs and having tried with 2 different amplifiers, I have to assume that it is the fault of the car's head unit).
The problem is that Chinese sellers are not very clear about compatibility;
for the fiesta from 2013 onwards there should be no problem, but I have a 2012.
In the past few years I have been looking for an android radio that would display informational messages on the display and allow the car settings to be adjusted (as is done with the original radio), but it was not possible for fiestas from 2008 to 2012.
I would like to keep the vehicle information messages (such as for open doors or climate controls), I would also like the steering wheel and facia dashboard controls to work; if it could also work the bluetooth would be great! (I have a sony car radio, the one with black facia, with usb and bluetooth, no synch).
Among the various I contacted is Witson, but they were unclear and contradictory about compatibility; one employee told me that it is compatible, another told me that it is not compatible.
Even the employees of belsee, jdaston and Ljda have told me that their units are compatible with my car. but I found no reviews about it.
is there someone here on the forum that can help me, maybe someone who has more information or who has installed one?
Thanks
PS
I am attaching the images of my car and radio model (2012 Ford Fiesta, titanium version)

Hello,
I have similar thoughts and installed android head unit to my mk7 facelift fiesta (2013) I'm new on this things but I will try to help.
After the installation of head unit, I still have the information messages for ac and doors, steering wheel and dashboard buttons are still usable(adapted to new system for different functions). My usb and aux port is still working. The system I have has bluetooth, wifi, gps, carplay/android auto(wifi and cable), other apps(play store), rear view camera. Only rear parking sensors not showing on system because they're not car spesific theyre universal parts, I you have original sensors they will also shown in screen. All this compatibility comes from canbus adapters, theyre spesific to car model which comes with head units and it manages all the communication/adaptation with car, So If head unit you looking for is specified for your car, everthing has to be similar in your condition too.
Before I had this unit. My car is fiesta 1.0 ecoboost titanium x , in Turkey it comes with this unit.
After installation, this is my unit ''AC8227L'' 1gb ram and android 6.0 version, exact same design with picture
I did some modding on theme of course and this is how it looks now
I also modded new boot logo with little photoshop

Car notification example
If you had anything as a question, just let me know

How is the sound quality? I installed a similar item, but 9 inch. Sound quality is really poor compared to factory radio. The OP is having a Sony radio so I think changing it to a chinese android radio would be multiple steps backwards.

thanks for sharing

Where did you buy it

Dasaita PX6 MAX10 - MCU Amp App

I have a Dasaita PX6 MAX10 which originally shipped with below software version.
Shipped Versions
Build Number
rk3399-userdebug 10 QQ2a.200305.004.A1.eng.htc.20200725.171818 test-keys
Mcu Version
MTCE_HA_V3.57_1
I updated to HA3_rk3399_10.0_ota(20201113)升级包 and MTCE_HA_V3.67 and after some testing I realised in the amplifier app the option for FREQ CUT was so aggressive compared to the shipped version. Even on the lowers setting 60hz it seemed like it was taking so much more out of the sound then before.
I flash back MTCE_HA_V3.57 and kept it on the latest software HA3_rk3399_10.0_ota(20201113)升级包 and it functioned as it was shipped before, FREQ CUT was working as expected. Then I tried to incrementally update the MCU to each higher version but anything above MTCE_HA_V3.57 would reintroduce the issue.
I should mention that I am using RCA outputs for front and rear audio.
I also realised that even on the shipped MTCE_HA_V3.57 the FREQ CUT option in the AMP app has no effect on the rear speakers it only works with the front audio.
If anyone has some advise would be appreciated. Thanks

What does reseller suggest when contacted for support.
Also, was the unit fully powered off, disconnected from battery after MCU changes?

I did not try to disconnect the battery after MCU flash.
I haven't contacted the reseller about the MCU flash but they got back to me and said from their engineer that only the front RCA has CUT FREQ.
