I know you posted this a while ago, so I may be beating a dead horse here...

But the geekbench results are actually significantly less than the PX6 on single core tests. Multithreaded though the Intel scored higher.

So really, the end user experience may actually be quite a bit better on the PX6...
[FYT Android Head Units] julien_blanche:
I think it's not worth it to buy Intel head units just because of CPU power itself, there are so many bugs and no solutions yet. Best logical action would be the buying popular products like px5, px6 etc.

Currently i have regrets for buying it, how hard could it be the solve Bluetooth application full screen problem. There are several bugs like this and this is unacceptable, just makes you tired while searching the forums to trying to solve the problems because of no product support by maker.

The purpose of these products should be the replacement oem units without too much hassle, not to be sale with pre-mature uncooked retail software.
[FYT Android Head Units] tangcla:
Manufacturer support has been great, I'm in constant communication with Joying regarding product feedback and they've been great.

Also remember the cost of the item - an OEM or branded product like the Pioneer would be triple the price of the Joying, with even less support.

I've tried contacting Pioneer for head unit feedback and they didn't even bother to respond.
[FYT Android Head Units] julien_blanche:
Maker support is not great at least in my experiences, when i report a problem to them i got nothing regarding the cure, they just saying we will pass it to our engineers and they are working for it. After a while i get a message that saying sorry for your problem but our head unit or software works in this way :) So this is hardly called as support...

I am not against all android head units, just saying that most popular ones would be more reasonable choice regarding the custom roms and solutions by the users.

cheers
[FYT Android Head Units] merdok:
I have had this response as well. But then some good email response with other issues. My support over last 2 years has been hit or miss.

They need to embrace xda. Creating their own forum is nice, but when issues get escalated they request email. Then no one sees the resolve. Hurts the purpose of a forum.
[FYT Android Head Units] merdok:
Does everyone just apply firmware upgrade on top of last?

I remember with Sofia would loop the process. Something like factory reset from settings, upgrade firmware, factory reset from settings.

I have had some strange issues have not been able to pin down. Wondering need to still do this routine.

Issues:

I cannot get unit to set default volume after resume (power off car and start car). Also when I applied current fw then factory reset introduced an issue with display having blue/white hue. At first thought they changed the menu color theme then noticed Spotify looked weird and saw flickering on certain colors.

For color test image it showed flickering on all the marked colors. I still show nav bar issues that was reported gone. Oh I wish we had a custom recovery
[FYT Android Head Units] tangcla:
Yep, just install it over the top.
[FYT Android Head Units] andTab:
Well. I pulled the trigger on the 7inch single DIN, 4GB+64GB with SPDIF and 4G: JY-UOS03N4GS.

[FYT Android Head Units] bersercci:
Haven't found a working solution or apk.

Anyone know if it can be done with rooting/magisk/xposed/... Anyone got Netflix working on the new Joying models with Oreo?

---------- Post added at 09:34 AM ---------- Previous post was at 09:31 AM ----------

Same here. Overall experience from Sofia to Airmont feels like a downgrade. No Netflix, sound distorted, Spotify keeps running on startup (at least they fixed the google voice and notification bar issues with 2019-5-15).

Yes it is faster, but pretty annoying when it comes to all the defects and deficiencies.
[FYT Android Head Units] Cr4z33:
Perhaps it depends on the current microphone you are using there?

In my home living experience my several Google Home devices work actually very good under high noise conditions (loud music, people chatting all together in the same room, hair dryer on, etc.)! ;)

[FYT Android Head Units] Black6spdZ:
I too am having some regrets about this unit.. so far besides being a bit faster and newer android over my older Newsmy NU5002 I am really upset that something as basic as running a BT OBD2 adapter in a "vehicle android head unit" doesn't work properly. Second, even though the SSID is saved on the unit, often when I get in my vehicle, turn on phone hotspot I have to go into wifi settings on the Joying before it decides to connect! And lastly, while the TPMS is new to me and was working in April firmware it is now broke in Mays release. One step forward and about three back!
[FYT Android Head Units] merdok:
I have had this happen with saved ssid. Short term fix was long pressing wifi icon from notification pull down, it would the just connect automatically.

I found going into the back / wipe screen and selecting the wifi option in there. Then adding ssids again worked properly
[FYT Android Head Units] mrchief1985:
So currently the may firmware is the best one to use?

I'm on the april firmware with the messed up voice in google maps and Waze crashing. Is this resolved in the may firmware?
[FYT Android Head Units] Theo164:
Voice in google maps works flawlessly with May firmware...

External microphone does not work but internal is ok

Volume reset to the default preset value does not work after turn the car off/on

Bluetooth calling app does mot minimize and is always on top during a phone call… its annoying while I use navigation
[FYT Android Head Units] tangcla:
But you can press the Nav button and it'll go back to home. You can't use the lower half of the screen but it's better than before.
[FYT Android Head Units] phatass_dk:
Does this new unit still have the issue of missing GPS lock after having turned the car on and off?

External microphone really needs firm pushing into the socket. You really need to hear an audible "click" otherwise it will not work.

Yesterday evening I just released my latest version of my JET apk (root required), that allows to put the BT app in the background while having a call (actually it allows to have another app in the foreground).

Are you able to make calls with Google Assistant? Mine just says "Sorry, not able to do that yet".
[FYT Android Head Units] Theo164:
No i get the same answer... "not able to do that yet"
[FYT Android Head Units] Cr4z33:
I got that with previous firmware and having installed Google Assistant manually from the Play Store.

As soon as I upgraded to May firmware (and data got reset) it works perfectly, especially by using it in HUR.
[FYT Android Head Units] rigattoni:
Why??? :confused:

At normal usage with navigation, mp3 decoding, Blitzer.de, Skype at an outside temp of ~32°C the CPU is on a 4 hrs drive at ~ 70-75°C, without any hardware modifications.

The CPU usage is only 10% of the time at 100% for less than 5 sec.

As far as I could see, there was at no time a CPU clock reduction necessary.

I just want to understand your motivations to do what you want to do.

The bench test does not show real usage. I would go with you if you could show an overheating while regular usage... but I assume you won´t be able to show that....

sorry... you can do what you want to do, but this is not really needed.
[FYT Android Head Units] julien_blanche:
Agree with you but this modification may help the keep fake Chinese capacitor life last longer because of capacitors does not like hot conditions. Also I am sure that input voltage cap is not tough as stated 105 C.

Hi guys,

i installed the first APK shown in this post https://xdaforums.com/showpost.php?p=73345810&postcount=37 on a JY-VO130N4G and it looks like Netflix is working.

At startup it will ask you to update the app, obviously don't do it.

Hi, i know it is a very old post but i'm fighting with the universal steering wheel on a Joying specific for VW... :crying:

I still don't know if i'll be brave enough to play with the welder, mee too i'm a software guy, but i was wondering if JOYING sent you precise information on the HW modification to do.
[FYT Android Head Units] Cr4z33:
I don't know what Joying unit and adapters you bought and what VW you have, but all I can say is that at first it looked hard and confusing.

Loads of cables (most of which weren't needed in my car), but with a little patience and lots of email to Joying support team I was getting the picture of the whole situation.

Long story short it is much easier than what it looks at first, but you have to be double sure about what you need to buy (adapter, etc.) and how to connect everything.
[FYT Android Head Units] bambapin:
I have a Passat and i bought a JY-VO130N4G which is supplied with the can bus decoder.

I must say that everything works including the integration with the reverse camera, information on levels, doors, climate etc. and also the unit is very fast, much much much more than my previous one.

The problem is that the car does not have the original steering wheel controls, before this new radio i had another headunit android always specific for VW that had a CAN BUS decoder that split 2 KEY1 and KEY2 wires that could be used to connect an universal SWC (the wireless ones found on aliexpress): in short words it was enough to connect the universal SWC outputs to the KEY1 and KEY2 cables coming out of the CAN BUS decoder, in this way the universal commands were recognized and the other functions of the original CAN BUS they kept working.

It seems that these new JOYING models no longer allow to receive external signals (and in fact there are not even split cables).

I could not understand if it is really a HW problem or if it is simply a SW limitation of the app that deals with learning: if it really solves making the system believe that the MB is universal, it makes me think that maybe in some so you could circumvent the limitation also via SW, even if at the operating system level.
[FYT Android Head Units] Cr4z33:
Are you just supposing this or did you have confirmation from Joying support?
[FYT Android Head Units] bambapin:
The Joying support told me that it is not possible at all, then i read about the 2 resistors modification on your old post.
[FYT Android Head Units] Cr4z33:
Aha now I understand! [emoji16]

Send information and pictures to the guys at http://connects2.com/ and see if they have what you need.

I did it and they had the needed adapters without having to solder a thing. [emoji57]
[FYT Android Head Units] bambapin:
Thank you but the Joying's support did not give me any information on what to do, that's why i asked Surfer63, who has a VW radio if he had the information :)

Indeed i think my situation is opposite to yours, if I had factory SWCs, they would work without any adapter, i have to make universal SWCs work.

Alright then. [emoji6]

I still did not do it either. Just like you I'm a software guy, not a hardware guy. I do not even have a soldering iron.

I have been thinking of ordering a universal motherboard for my unit. The dimensions and connections are 100% the same.

But: If I screw up with soldering I can still buy that motherboard. The motherboard in my previous Sofia once completely failed. Then I got a new motherboard for 40~45 euros or so.

Next time (if there is a next time), I will order a VAG unit (because of the formfactor and facia) with a universal motherboard. But I might have another car as well when that happens.

Below the mail from Joying.

==============================

Hi Harry,

Glad to hear from you, hope everything goes well with you :)

If you do not need a canbus system. that is ok, can you change the resistance by yourself? If yes, you can change your current VW motherboard to universal motherboard.

Move below 2 resistance to the arrow place, it will become a universal motherboard. Then you can use that external SWC device.

<image attached>

Here is a short video for your ref about how to move the resistance to other places: https://youtu.be/ukSpJDFXHRY

Best regards

Mandy

==============================
[FYT Android Head Units] bambapin:
Thanks a lot! Watching the video i realized that it's definitely too scary for me :)

If i can find some free time i would like to investigate if there is a way to use the universal SWC control unit bypassing the can bus, for example to send signals (perhaps using an arduino in the middle) via usb or bluetooth to the headunit.

This way perhaps it would be possible to create a service on the headunit to intercept the signals and use them in some way....

Hi,

Were you, or anyone for that matter, able to get BT car adapter working. I just bought a fancy auto off ODB2 adapter but it never shows up. The adapter shows up on my phone just fine.
[FYT Android Head Units] bambapin:
Hi, i suggest to ask directly Joying support, at least in my experience they respond quickly.

I used this email: support@joyingauto.com
[FYT Android Head Units] surfer63:
Joying crippled both USB and Bluetooth. Already since the Sofia models.

For USB they do not allow dash/web-cams. They have a "white list" with usb dashcams that they sell and they block every other usb web/dash-cam.

For Bluetooth they allow phones, HID devices (mice, keyboard) and ODB2.

Your OBD2 not being recognized is a bit strange. How does it identify on your phone?

The BT app also checks for "OBD" in the identification name string.

Hi, I'm thinking about doing a similar mod, how are you powering the fans? Does the motherboard have spare fan connectors or are you using an external pwm controller?
[FYT Android Head Units] Theo164:
Power is 12v from ACC (12 - 13.5v) i installed 2x NA-RC10 low noise adaptors to keep maximum voltage close to 12 ) every time i turn on ignition switch it power on fans and HU

5v fans is an option too powering them form the usb headers

In my car head unit is in front of the A/C evaporator and below - above of the air channels it gets cold in there

I did the same test like yesterday to make sure everything is ok this time with ac on

Do you think that Android 9 would be better?

Let me say it like that: NO!

Any stable 8.1 is better than a new 9.0 version... and there is still a lot of place for getting better on 8.1.

[FYT Android Head Units] rigattoni:
We are here talking about a real new unit and yes, there are still some issues in the firmware.

If we would be able to increase the pressure to fix the known issues and missing features, that would help a lot to increase the priority on their side.

We should create a list of issues and missing features and send it to Joying. May be we have luck...

All,

I'm trying to make a final decision between this platform and the newer Dasaita px6 dsp units. Since this platform has been out for a while I would love to hear about what you love and hate. Below I've done my best to list pros and cons for each unit / platform. I am looking at the "universal" 10.1 /10.2 inch screen options in double din form factor. Feel free to weigh in if you have any thoughts please. More than anything, I'm looking to hear from anyone that is using these units built in amplifier with either factory or aftermarket speakers. Sound quality is important to me and it appears the mosfet amps / chips are virtually the same for both these units.

Dasaita px6 dsp pros:

Android 9 vs 8.1

Rockchip platform seems to have more longevity / development vs intel ?

Mali 864 vs Mali 820 (not a huge deal)

Faster single core performance

HDMI out (nice to have)

2 camera inputs

3 1.5 amp usb outputs

Cons:

Need to purchase android auto / carplay dongles separately (100+ for both)

No spdif out

Screen not easily / quickly removable

Unsure if canbus adapter for chevy cruze is compatible

Joying 8.1 intel DSP pros:

spdif out

android auto / apple carplay support built in via zlink

Easy to remove screen

Seem to have good technical / customer support?

Joying makes a direct 7 inch oem style replacement for my 2011 silverado vehicle, which makes getting harness / canbus adapter easy....

Faster multi core performance from CPU

Cons:

No video out

Android 8.1

usb / bluetooth limitations?

overheating issues potentially (live in phoenix lol)
[FYT Android Head Units] ozzyboy:

I have few questions

from where you get 12v for vents (acc12v+ or directly from battery) and 2nd question, you didn't use the up cover on HU after you install the vents?

Hello,

guys i'm planning to buy this unit and i saw that it's 40$ cheaper from China store but would it be any custom taxes fee applied when delivered to Belgium, France or Turkey ?

Thanks a lot for your answers !
[FYT Android Head Units] julien_blanche:
Joying store declare the item value $80 or whatever you request from them when they ship it but it does not mean you won't pay custom fee at all, it depends on custom officer judgement. For the Turkey you may be charged extra %20 additional with %20 import fee because of the special tax, for the Europe this is subject to change depends on declared value of the item...

Thanks Julien..for your reply...I saw there was a 25% off coupon for the black friday....i guess there will be also some sale for the summer sale period...i think i'm gonna skip the father's day deal 12% and wait for the summer deal....

[FYT Android Head Units] julien_blanche:
If i were you i would skip this head unit forever and go for a new px6 :D, anyways i got mine for about $370.

I saw the PX6 but i was thinking this is way better than the Rockchip PX6...
