Viewing angles

VIEWING ANGLES

If anyone is curious to know how the viewing angles are on the joying units. This one is on my rav4. I dont know if there is any difference compared to the others like their universal ones. Its unlikely since im sure they use the same type of panels ....just different sizes.

Heres a video i uploaded on youtube

Looks like theres a 6.0.1 update now. Has anyone tried it yet?
[MTCD Android Head Units General] bogdi1988:
I don't see an upgrade link
[MTCD Android Head Units General] thedru13:
Me either
[MTCD Android Head Units General] bogdi1988:
Apparently it's coming out Monday - from another thread
[MTCD Android Head Units General] kampfschachtel:
the 8inch and 10.1 inch panels are the same but different size and come actually from tablet screens. The 7 inch ones are totally different panels, standard radio ones. Viewing angle on 10.1 is much bigger due to from tablet then on your 7inch.

The issue with the 10.1 is at night due to white is very bright at night, even if you put brightness fully down. All apps possible have already swithched darker "night version" but I will put a slightly taned anti glare protection folio on it, that should solve this issue. Otherwise happy with it, fast and good picture.

that's great. Happy if some of you test it and also check if the mods are still runing. Not a developer, so I will wait till the pro's here figure out how well it runs and what bugs our chinese friends delivering this time:eek: as a surprise package
[MTCD Android Head Units General] simpl3lang:
Joying's YouTube channel just kept releasing how to upgrade videos last Friday. That's how I found out they have an update.

I see. that's a bummer for me cause the one I got for the RAV4 fits perfectly in place of the stock unit....its cleaner looking, doesn't stick out and doesn't obscure the AC vents. I do want a 10.1 screen...and if you say it's better than what I have then I might just try it. Sell my 7in screen android unit for to my sis and buy the 10.1 ....I'm sure it will block the AC vents and that's what's stopping me from buying it.

Can you make a video on YouTube showing the viewing angles on the 10.1 screen? Thanks
[MTCD Android Head Units General] bugluv67:
I have a stupid question. How do u find the model number you have? I didn't see it anywhere on my unit.

This is the one I bought. It great. Was an easy install on my 03 Deville. Works great.

[MTCD Android Head Units General] bugluv67:
Thanks for the info. Now if I may. Is this the newest model? There's another quad-core 2gb model listed also. It looks similar but the knob is in the middle of the left side. I'm asking because I am about to buy a 2nd one. And I want to be sure I get the fastest most updated model. The joying amazon listing and website isn't very clear about this. Other than saying it's has 5.1 and quad core.

This is the one I'm referring to. Or if there's a different model that's newer.
[MTCD Android Head Units General] bogdi1988:
The one you have is the latest. Look on the specs to have Intel Sofia CPU and 2gb of RAM
[MTCD Android Head Units General] bugluv67:
Awesome thanks for the info!

Guys - is someone else of you struggling with the factory radio app? I'm having the issue, that it jumps to other frequencies all the time, although the reception is not too bad. It just jumps arbitrarily to other frequencies that sometimes don't have any reception at all.

What's the capacity limit on both the SD card and the USB mem sticks that I can use with this?

Would it power a 2.5" USB HDD?

Is it possible to make the OS use the SD card as internal storage?
[MTCD Android Head Units General] naplesbill:
Does it coincide with your phone and notifications?
[MTCD Android Head Units General] wanb1i:
I've got a 128gb sd in mine, works great. Someone else indicated they used a 256gb. Must be formatted as fat32.

It powered my 1tb western digital drive.

No on the sd as adaptable storage.
[MTCD Android Head Units General] romprod:
Do we know the spec's of the SD card slots and the USB ports?

I'm guessing the USB ports are plain USB2.0 but unsure of what speed the SD card slot will be?

I have a USB2.0 to SATA3 adapter that I guess I could connect an SSD to. That should be fast enough and shouldn't cause any issues.

USB Hub / Intel Joying Power Issue

I'm having a problem.

I have a USB Hub that shares the same retained power circuit as the Joying Intel Headunit. When the HUB and Headunit is connected to the retained power circuit and NO USB connected between the two, I turn the key, everything is fine, the HUB powers on, the head unit powers on. When I turn the key off, everything is still fine, the head unit turns off, the hub turns off.

The problem occurs when I connect the USB cable from the Headunit to the Hub. When I turn the key on, everything is fine, the head unit and hub both come on, HOWEVER; when I turn the key OFF, NEITHER the Headunit OR USB Hub will go off, BOTH will stay on INDEFINITELY and NEVER go off.. yet separated (no USB connection between the two) they both go off as intended)..

It SOUNDS like, Battery power (always hot) is going through the radio and into the USB cable and into the HUB, from the HUB it is going BACK through my retained power circuit and INTO the head unit, keeping retained power ALWAYS on .. thats what it seems like. If I disconnect the USB cable both devices lose power.

Any idea as to how I could prevent this? Is there any setting in the HU that will allow me to disable the power going into the USB cables since i have external power already?
[MTCD Android Head Units General] Saiyajin:
Nope - jumps completely on it's own. Sometime like 4-10 times in a row, even after adjusting the station myself. It's driving me nuts!

2. Did you open the Google app and approve the permissions requests?
[MTCD Android Head Units General] cormoo82:
I have this exact same problem and it is driving me nuts! Did you solve this by chance? If not is there an alternate radio app we can use?
[MTCD Android Head Units General] surfer63:
This is due to the fact that they implemented RDS AF incorrectly. AF is to find the strongest altenative frequency for the current radio station.

Joying, or actually their software supplier SYU, interpreted it as "simply find the strongest frequency", like in any frequency available.

You better switch off AF on your radio app.

I have my Joying since January and since that time I have been mailing them. They seem to understand the issue now, but they only mention that it is better to switch off AF. They say nothing like "We are working on it and will supply a correct version on ...".

It seems to happen on more Chinese head units. Very stupid.
[MTCD Android Head Units General] Saiyajin:
Thanks for the insights. Not sure though if that is the "solution" even with AF off it is switching pointlessly to other frequencies, even if there is no signal at all.

Change the LED's

Hi all. I posted this question in another thread but this might be a more appropriate place. One of the main purchasing factors for me was the orange LED's pictured in the ad for the headunit. But I only have 7 color options, and the "orange" is actually green/yellow. Does anyone have a mod to edit the colors available? Or perhaps recommend a different ROM than the one that ships with the unit? Alternatively, I'm willing to dig around - if I knew where the app controls for the "lantern" setting were stored within the rom... I might be able to decompile and edit the hex values. In earlier versions of Joying units they had much more customization over the LED colors... would love to see something like that return.

Missing Phone Dialer / Bluetooth App

[MTCD Android Head Units General] Barton261:
I'm looking at getting the 2g ram 32gb rom model. I have a aftermarket overhead DVD player in my suburban currently with an Sony in dash DVD player with 6.2 inch screen. Currently with my setup I'm able to play video files from a thumb drive and it will play on both the indash and the overhead DVD player. I can also navigate away from the movie or turn the indash screen off and the movie will continue to play on the overhead unit.

Can anyone tell me if I can do this on a joying unit? I want to be able to play movies from sd card or thumb drive to overhead monitor while also utilizing Google maps or another app. Or will the overhead monitor just display exactly what's on the screen on the joying?
[MTCD Android Head Units General] wanb1i:
According to the specifications of the new unit there are 2 video outputs for rear additional headrest tablets. And the main front unit can operate independent of the video player. There are 2 USB2.0 ports for various options. Some models also have DVD players.

Use caution on these new units, I have just received the 8" single din unit and I'm having issues with Bluetooth Music and bad FM Radio reception. I get my car back from Best Buy today and will do a thorough review and post the results here.
[MTCD Android Head Units General] Barton261:
I understand there are multiple video outputs. My concern is whether or not a video will continue to play and be displayed on an external monitor if that is not what is shown on the units display. Example: I start a movie and then switch to google maps. Is my external display going to show the movie or Google maps?
[MTCD Android Head Units General] wanb1i:
Please READ my response to your request. "And the main front unit can operate independent of the video player." To me, that sounds like a positive answer to your quarry.

BTW, thanks for taking your personal time to respond to my question.........:highfive:
[MTCD Android Head Units General] Barton261:
Just for everyone's clarification I got an answer from the company rather than relying on this joker to provide bad information based on his/her opinion.

The answer: The units without a DVD player can not support video out functions from any app or anything displayed on the screen. You have to hook up an external multimedia player to the video in and whatever is playing on that device will be what is shown on the video out so there is not DAC in these devices. No streaming .avi/.mp4 files. Furthermore it will not use more than one app at the same time the caveat is to update the firmware to allow PIP view which will give you a windowed video player inside whatever app is open.

Lastly the models with a DVD player operate in the same manner only they do not require a video in multimedia device as the DVD player is built in. So essentially these things are useless. The Sony DVD player I have now provides more functionality currently.. (which sucks) as I can play files from a thumb drive and have it displayed on my overhead monitors.

I'm hoping in the future they will upgrade them to include a true video out rather than an RCA pass through.

worked great the 1st time. I recommend doing the update first. Also, be sure to get the steering wheel control schematic from you dealer. Don't depend on vendor diagrams, they're not accurate. I bought $100 worth of cables & adapters I didn't need because I listened to the vendors!

Do that first, otherwise you'll loose all the changes you made.
[MTCD Android Head Units General] doitright:
The first time Android boots up on any device (i.e., following a factory reset), it usually has to optimize some applications and make some configurations before it can complete boot. In the absence of many "installed" programs, it does not seem unreasonable to expect this optimization to take around 10 seconds, especially on an Intel CPU.

---------- Post added at 04:28 PM ---------- Previous post was at 04:21 PM ----------

Didn't you read the instructions?

adb connect {IP address}

adb root <-- oh, what? Yep. That command switches adbd to provide you with a ROOT SHELL, i.e., it is PRE-ROOTED.

The rest of the instructions after that are to replace AOSP root with that supersu junk. Don't trust supersu.

---------- Post added at 04:52 PM ---------- Previous post was at 04:28 PM ----------

That RCA passthrough thing is pretty strange. I'm guessing that it can be used to take the video source and display it both on the head unit and split it off to an external display?

In any case, I think your best solution to this ridiculous situation will be to use something like a raspberry pi to drive the external display. If the external monitor has HDMI input and its own speakers, you can probably get by with a pi zero ($5), otherwise you'll need at least a Pi 1 A+ with A/V outputs. I'd probably recommend the Pi 3 B though, since it has WiFi, which would allow you to control it from the head unit over the network using very trivial HTTP commands.

However, note that using wifi for this will complicate access to your cell phone network. You'll either need to switch to BLUETOOTH tethering to your phone (which the Joying units are able to do, with a minor hack), or they will both have to connect to your phone's hotspot and communicate through your phone, OR, you will have to do some custom networking in order for the access point (head unit) to obtain its network from a client (phone). Yes, this third option CAN be done, but is considerably more complicated than pressing the "wifi tethering" button.
[MTCD Android Head Units General] demo84:
What instructions? You mean the one that is supplied with the radio? Oh yeah it's in German even if the radio was sent to Great Britain lol

Anyway I got different problem now. The side buttons not lit up at all. They stay black. I know there is settings for that but they don't change anything. Even settings for color change has gone :eek:
[MTCD Android Head Units General] doitright:
You responded to a post by [MENTION=2856632]wanb1i[/MENTION] -- that post had a link to "instructions" for obtaining root. You responded to it, so I assume that you had read it.

About the side buttons... they are controlled by the headlight circuit, so most likely either you haven't connected your headlight wire, or you haven't turned your headlights on. It will be the ORANGE+WHITE wire on the joying harness.
[MTCD Android Head Units General] ikerg:
On mcu settings (factory settings) you can enable disable led light for buttons.

On Android settings you can adjust the color

[MTCD Android Head Units General] demo84:
Yes I haven't connect any wires to the headlights. I didn't know that I have to. So here is the settings for side buttons. What shall I choose without headlights connection? at the moment they are set to TIME CONTROL but when I put the engine off buttons stays ON for like 10min :eek:
[MTCD Android Head Units General] wanb1i:
I don't think the Time Control setting is for the side lights. It says it's "Back light". My lights stay on as well when I shut the car off. I'll check that setting and post the results.

That setting has nothing to do with the side lighting. I noticed that I had left the headlights control in the ON position (auto headlights) and that's why my side lights stayed on.. So if you have auto headlights, be sure the switch is in the off position and see if they go off when you shut the car off. Mine do now.
[MTCD Android Head Units General] demo84:
Please have a look. This unit without manual is driving me crazy lol so many options
[MTCD Android Head Units General] doitright:
That sounds like it is probably matching up to the amount of time that the radio remains on (whether the screen is on or not) after you turn off the car. It does that so that you don't have to completely boot up after you do something short, like fill the gas.

I really would suggest hooking up the wire to your headlights. Most cars factory radio wire harness should have a signal for that you can use.
[MTCD Android Head Units General] demo84:
Thanks will have look tomorrow
[MTCD Android Head Units General] wanb1i:
So there is a manual of sorts. It's an app called "Operational Guide" or something like that. It provides some guidance, but not all of the needed information. There are also several videos on YouTube that I found helpful, unfortunately, they're done in broken chinglish, which requires focused concentration to understand. That's another reason why I rooted the device, installed Nova Launcher and built my own UI.
[MTCD Android Head Units General] demo84:
That make more sense! I hope this device on xda evolute more and we will get nice stable custom rom or at least custom recover :D

Hello everyone.

I have an aftermarket chinese 2din on my Merc which is absolutely garbage, not android based. BT audio quality is terrible and radio reception is poor.

I'm looking to replace it, and first I thought to build a custom setup for my Nexus 7, but it's too much work for me.

I then found info about these Joying units, and I'm considering it as an alternative.

I can buy a used one at a reasonable price, but it's the 1 GB RAM version JY-UL124.

https://www.carjoying.com/android-5...ehicles-support-mirror-link-dvr-dab-obd2.html

Will the extra 1GB of ram make a huge difference in terms of boot time, multitasking and stability?? I'm going to use it for connecting my Samsung Note 4 for calls and music, WAZE, and random video watching on youtube.

Should I leave it and consider the new 2GB models?

Besides, is it possible to connect my Note 4 and use USB tethering instead of Wifi tethering, and charge the phone when connected to USB? This could be really helpful.

Thanks!

You'd be better to ask that question in this thread:

While you're there, consider putting that rom on your used unit. Many have and appear to be pleased with it.

I don't see why it'a better to be posted there. It is a thread about a specific custom ROM.

It's a rom, for that specific unit where people who have that unit can answer your questions.

This thread is NOT about that unit, but a much newer and totally different architecture system. Most of the people on this thread don't have experience with that unit. That's why.

Personally I wouldn't buy anything with less than 2GB ram. That's why I was waiting for 2GB Joying unit

I had before unit with 1GB ram and it was horrible experience. Never ever any unit with 1gb ram. But that's my point of view
