I am thinking about installing a rear cam and can't decide whether to go with the joying one or the original from VW for my Passat.

The joying one is much cheaper, but I think the quality might be worse than the VW-rear cam and the installation isn't as nice, as I would have to screw it onto something right?

Has anyone here faced a similar decision?
[FYT Android Head Units] ste2002:
I have Joying rear cam installed, and it is quite OK even in darkness. In order to use VW cam with Joying HU one have to purchase Joying adapter for $70. I've purchased it - just in case, since I still have also VW rear camera installed (but disconnected). Above is relevant for B6/B7 VW generation, not MQB.
[FYT Android Head Units] derschnelle:
Thank you very much for your quick reply.

My Passat is a B6, so I would have to get the adapter ~70€ and the VW-rear cam (low) ~130€.

Do you think it is worth, spending the extra money on the VW-cam instead of the joying one?

How did you mount the joying one? Screwed on the license-plate-holder?
[FYT Android Head Units] ste2002:
I did not have a chance to check how VW camera works via adapter with Joying HU, only with factory RNS-510.

If you still want to purchase VW camera and adapter - rather pricy items - just spend another $20 also for Joying camera - no big loss - so you can later compare/choose. As I've already said, Joying camera with dynamic lines suits me OK. I do not believe it is as precise showing lines as calibrated VW set (with RNS/RCD-510), but I think with that Joying adapter you are going to loose all that VW precision. As to video quality - it is quite comparable to factory VW.

As to install method - no, it was not LP frame, I have Skoda Superb and installed camera under 5th door using supplied bracket.
[FYT Android Head Units] derschnelle:
Man you are helping me very much, thank you. I just ordered the joying cam and will try it out first.

I still don't really know, how to install the cam, but I will have a closer look when it arrives.
[FYT Android Head Units] edit:
I would go with the original because :

1. The original has glass lens that are or higher quality and last longer,

2. It has the correct angle so you can see your bumper as a reference so you know how closer can you get to the objects before scratching it. Some Chinese cameras do not have the right angle so you don't see your bumper when you reverse... you have to guess where it is and you don't have such a great precision. Yes, in time you can adjust to that but it's not the same

3. Usually the original offers better quality but the downside is that you have to cut wires to adapt the camera to the Chinese units because the original has custom plugs

4. The original camera has the optimal field of view (140-170 degrees) so you can see all the rear bumper and then some

5. The original camera usually has better low light sensitivity

6. the original camera is mounted more discretely and looks better overall

My story : I installed an camera more then 3 years ago even if I had parking sensors and I found it so useful that I can't live without a camera now. I was lucky that I got a good one, decent picture, right angle (I was able to see my rear bumper) it was in a fixed position, not adjustable (not that it needed) and also served as a plate number light, very discrete. The problem is that after 1-1.5 years the lens started to degrade rapidly, were made of cheap plastic (of course, Chinese merchandise) to the point that I wasn't able to see more then 0.5 meter behind my car... the imagine was white, the lens were matte. So I exchanged it with another camera (Chinese) and to my surprise the new camera did not had the proper field of view.... on paper it said 140 degrees, in reality it was more narrow around 90-100 degrees so I wasn't able to see all there was to see behind the car. On top of that it did not had the right angle so the closest object that I could see was 1 meter away from my rear bumper... useless, uninstalled it and put he broken one back (lots of wasted time). Bought a new one, this one has the right field of view, the best picture so far compared to all the cameras that I had, better low light image (albeit it goes black and white but I don't mind) but it does not have the right angle so I can't get closer to more then 10-15 cm to an object because I can't see my bumper as a reference to be able to judge the distance properly....

I ordered 2 more cameras now from 2 different sellers.... I hope that I finally get one that works as it should...

My car wasn't designed with a back-up camera in mind and I can't buy an original one (or find one at the scrapyard) ... if I could I would get one in a heartbeat....

I agree that I have higher demand from hardware compared to lots of other people and quality for me it's important. I'd rather spend a bit more money to have higher quality item with a longer life than spending lots of hours (and money) changing different cheap cameras till I could find one that really works as it should and fits.
[FYT Android Head Units] surfer63:
Do you have the mixed GPS switched on? Meaning using the GPS and Glonass satellites. Using both increases accuracy a lot.
[FYT Android Head Units] sanangel:
I also have a Passat B6. I installed an aliexpress camera and I am very happy with it. Obviously it is not 4K quality, but for the use of the car, it is almost perfect.

No separate adapter is needed, it is plug and play.
[FYT Android Head Units] surfer63:
As mentioned earlier in several threads: It is not the image quality as such. It is the durability.

These cheap alieexpress cams have plastic lense which wear out relatively fast.

After 1 year of use you can only see whether the car parked behind you is black or red. Not if it is a truck or a sportscar anymore. The plastic lense has lost all of its quality.

And for the price you can indeed buy 2 others,but it is a bit annoying to rewire the whole stuff.

Unless you use one of those cheap aliexpress 2.4GHz wireless RCA sets. Then you can change as often as you like.

This is how it works!
[FYT Android Head Units] edit:
The GPS cable plug might got loose at the back of the unit or the GPS antenna cable got damaged... It happened to me too on my old unit 2 years ago.... Same behaviour.

The worse it could happen is a bad soldering of the GPS cable on the SoM.

First check the cable for damage and the GPS plug if it's screwed in tight to the back of the unit ... Also would not be a bad idea to open the unit and visualy check the internal GPS cable if it's properly soldered to the SoM then buy a new GPS antenna it's around 50-70 Lei.

Good luck !
[FYT Android Head Units] sanangel:
If I'm honest, the camera that I bought is more than two years old and works the same as the first day.

I had it before Joying with an Alpine in my vehicle and it still works well.

On the other hand, I have a problem with Joying that nobody has reported.

I'm with the penultimate update (I have not flashed the last one yet) and when I connect the lights of the vehicle, the screen dims and blinks and if I'm traveling, little by little it goes down in intensity until it ends up being black. It's something very uncomfortable ...
[FYT Android Head Units] btrax:
Hi guys,

I want to buy the Joying Unit for my VW and i have some questions :)

First of all, it concern the heat, as I see many customers complain about the heat of the unit. If it's overheating the unit will stop or it will be just laggy (i plan to drive a lot and the last thing I want, it's that the unit won't work after one hour or two ^^)

And the second one, does anyone bought the unit with the Digital amplifier, does it worth it ?

Cheers guys :)
[FYT Android Head Units] surfer63:
I can only answer your first question: Yes, you definitely need cooling.

Before cooling I had temperatures up to 92 C while the max working temperature is 85 C. This will not make your unit "laggy", it will make your unit dead slow and unworkable.

Next to that your unit will die sooner or later: meaning (much) sooner.
[FYT Android Head Units] btrax:
That's the point I don't understand, why they sell that if the cooling is not sufficient ^^
[FYT Android Head Units] edit:
It's all about the consumerism world we live in, cutting costs, making more money... All the brands (big or small, famous or not) don't want their products to be easy and cheap to fix... either the repairs are very expensive or they want to sell you something new instead (more expensive) with every single chance they have.

Joying did the same with this one, they used poor passive cooling (heatsink) to save money and they totally skipped the active cooling (fan, although it's needed) to save money again... they probably estimated that the unit will last at least 1 year what's the general warranty period (except in Europe) and when the unit fails they are happy to sell you a new motherboard or offer you to buy a new unit... The world we live in they taught them too that if they play their cards right it will mean more money for them and no matter what it's a win-win.
[FYT Android Head Units] btrax:
So, does I need to put a big HeatSink or HeatSink plus a fan to evacuate the heat?

Hello,

It would seem that a sofia based android head unit is the way to go. I am curious though, is Joying the only manufacturer out there that uses them? It is unfortunate they do not have a head unit with the OEM look for most cars.

Those who have done the viper4android mod does that really get you as good or close to as good as a real head unit?

And how is the bluetooth streaming and audio calls at the end of the day?

Thanks
[FYT Android Head Units] derschnelle:
Hmm no one with the same problem?
[FYT Android Head Units] nk33:
i have noticed they released a new one ofe these - with all the same specs - apart from

It also has:

Android 6 pre-installed

Digital amplifier built -in - with proper cross-over built in

Here is the ebay link: https://www.ebay.co.uk/itm/Joying-7...788652?hash=item2f078793ec:g:T3oAAOSw3YJZW1os

can anyone verify this crossover works?

i currently run last years model, have not rooted and have not upgraded since i bought it as everything works well. I had to install a few things behind it to make it work properly with my speakers and sub:

1) Line driver to increase the output from the sub-out as the one on the unit was not enough

2) Amps for my speakers as the power output from the speakers was really low and poor

3) Amp on sub (had to do this anyway)

4) Relay switch to trigger the amps to switch on as the switch from the unit is so low and poor
[FYT Android Head Units] nyogtha:
Looks like this is only happening / is a problem with the dab+ app. Both Spotify and normal radio works without any stuttering when starting waze or google maps after.
[FYT Android Head Units] nexxusty:
Why has this turned into a help thread?

Are most people here THAT helpless? These are the best Head Units available and still everyone has issues.

I don't get it, really. Have had ZERO issues with mine.... not one.
[FYT Android Head Units] tuuza:
The units are far from completely functional ones. They have ALOT of stupid things that could be easily solved by Joying but they dont care too much.

Lähetetty minun E6853 laitteesta Tapatalkilla
[FYT Android Head Units] treel:
No problem.

I was surprised that joying don't allow that.

1.) there was little problem they allowed only to pair with devices that begin with "OBD" or "gooddriver"

2.) they have a bad logic in the pairing process.

One question is the apk working without problems ?

Yeah used Windows device and adb connect (ip)

Sometimes I'd get 'server out of date' or i get connected and when i try to do anything is says permission denied to write to system

Is there anything that has to be done to the HU first?
[FYT Android Head Units] tuuza:
If you are using the method 2, the command you should use is install (ip) , no need to use the connect. And make sure that the cmd is started with adminstrive acces.

Open CMD as admin, use CD command to go to the folder wich has all the files, type install (ip) and it starts to upload stuff to your HU.

Rebot and install cf superuser.

You can't do it over a mobile hotspot ... So both HU and Windows machine connected to the same phone tether. Needed to both be connected to a proper router.

Look up the thread with the mods. You need to enable immersive mode. If your do with * then status is hidden at all times.

Is there any way to get this to work :(

I've got it rooted, I've got SuperSU installed, I've replaced the server apk to stop tasks being killed but it does not do what i need. Which is...

I need the HU to not close an app for upto an hour. When driving from place to place i route a map into Good Maps and go from point to point but it seems if I'm out of the car for more than about 10 mins Google Maps does open again but forgets the route I've entered.

Any one have any fix or ideas? :fingers-crossed:
[FYT Android Head Units] booba5185:
I can't get immersive mode to work, I've tried all the apps and they either do nothing, erase everything on the screen except the background (thankfully a reboot fixes this), or the bar will still be there, but it won't say anything. How can something so simple be such s PITA?

Edit: I got it....when I tried the method listed on the first post of this very thread...face, meet palm.
[FYT Android Head Units] surfer63:
What do you mean with "crossover"?

It is simply a JY-UM135N2D. It is already quite some time on their own website like all the other "D" models.
[FYT Android Head Units] nk33:
a crossover allows you to adjust the frequency of sound that goes to each set of speakers. that way you dont need an external one.

so you want midrange going to speakers, highs going to tweeters, and lows going to subs....anything else would cause distortion.

look at the pics of the stereo in the ebay link - the pictures show nice crossover interface
[FYT Android Head Units] surfer63:
:D I thought you meant that Joying had built a crossover by "mixing" two models of them into a new type.
[FYT Android Head Units] nk33:
lol....

no that would be cross-breed hahaha

we are speaking audio here...cross-over is essential for good audio.
[FYT Android Head Units] DBestman:
Well, you can disconnect the cable from inside the head unit.
[FYT Android Head Units] KamaL:
I have a question regarding an android unit from another brand named UNIWAY model ATY9071, based on the Allwinner 3T chipset

I've been using my JOYING unit for a while and pretty happy with it even with 5.1, and I got a new 9" unit for another car, and I chose it because it was ready with all cables without the need of any adapter for the dash or cables

I'm facing two issues, and I'm asking here because the JOYING units have these 2 essentials features, so I thought I could some help here.

The seller on Aliexpress was really unhelpful, as in many cases with chinese brands..

https://www.aliexpress.com/item/uni...zuki-SX4-2006-2007-2008-2009/32825779273.html

1) BLUETOOTH TETHERING - as other chinese devices, BT is really messed up. I can't get into the bluetooth settings panel at all, not even using all kinds of tricks, and once connected to my android phone, I can use it only for calls and media, but there is no option for bluetooth tethering. I have to use wifi hotspot, which drains the phone battery quickly.

Is there a solution to fix this??

2) SHUTDOWN DELAY - the device has the option to stay "awake" after turning off the car, but to a max of 3 HOURS. This is not practical at all, so each time in the morning I turn on the car, it needs to boot to android for at least 30 seconds, and makes using GPS while driving very dangerous.

Is there an application that can keep it in standby mode with minimal electrical draw, so I can use it instantly in the morning, just like my JOYING unit?

Again, the seller was really unhelpful with these 2 issues, which are simply basic for a car stereo, so I hope you can help with this.

Thanks in advance!!
[FYT Android Head Units] nk33:
There are 2 apps for bluetooth - one is called blueballs.apk - this gives you the native bluetooth pairing module. there is another custom apk called bluetoothtethering.apk - this will let you connection share your android stereo from your mobile. i use this and you are rate - the battery drain is minimal.

as for the stereo needing to boot - this only happens for me if the weather gets under 2 degrees overnight. Otherwise the stereo will not switch off for days even if i dont start the car - it comes on instantly - wakes from sleep. there may be something wrong with yours...
[FYT Android Head Units] KamaL:
I think you're talking about JOYING units. My question is about a different brand, I'm looking for having these features that are found in joying units.
[FYT Android Head Units] nk33:

Problem with Joying Sofia

When I start my engine it could happen, that the device crashes with the error message: "Unfortunately, Mainserver has stopped". Then I cannot tap on OK, the device reboots automatically. Can I find any log files when the devices crashes? Is it possible to deactivate the automatic reboot? It's very annoying.
[FYT Android Head Units] surfer63:
The November version doesn't have the original Settings.apk. Probably because Joying doesn't want users to use that one anymore.

lbdroid deodexed the September one and patched it at the same time, because the developer options were broken.

Than one can be used on the November ROM.

See here.

(And in case you're asking why it is not in my apk: My unit is bricked for over 3 weeks now. I hope my new replacement motherboard will arrive Tuesday or Wednesday. After building it in (and some soldering?), I can continue with my apk as I don't want to release an untested one.)

Is there a way to have the title of the music/radio played in the screen bar. I remenbered on Malaisk ROM (On MTCB) it was possible.
[FYT Android Head Units] surfer63:
Hardly. The RDS-txt function is badly implemented.

Very occasionally you get this text automatically. In 99% of the cases, you don't get it.

I only get if from one local station (which I don't like), but I don't get it for all(!) the big mainstream stations.

I know from a few other users, that they have the same experience.

I was talking about having music title ( from Spotify, media player, etc...) On the screenbar, when I had a Rockchip device on my polo, with malaysk ROM it was possible. I hope it will be possible on the future :)
[FYT Android Head Units] surfer63:
Malaysk has the Xposed framework in his ROMs and most probably it was one of the Xposed modules doing that. There are a number of media player related modules, but I never looked into that.

AF works, if...

By accident I realized that the radio AF works quite well, if you preset the relevant frequencies in memory. My 40km test drive showed that the radio keeps my main radio station switching about 15 times between the preset frequencies without hearable drop outs. Maybe this info helps someone... ;)
[FYT Android Head Units] surfer63:
What do you mean with "switching about 15 times between the preset frequencies".

If I have one radio station like "Radio538" (in the Netherlands), correct AF would be to switch between the several frequencies in the 102.1 to 102.7 FM frequencies if I drive through the Netherlands.

Is that what you mean the radio app does?

Or do you mean it switches between the preset frequencies it self you setup for one station (like Radio538) (going from preset 1, to preset 7, to preset 3, to preset 5, etc.)

Or do you mean it switches between the preset frequencies it self you setup for some radiostation 1, some radiostation 2, some radionstation 3,etc.?

And the radio of which ROM version? November or December? Joying/SYU made a lot of internal changes in that radio app using completely different libraries..
