will the above work with my rooted joying unit running 6.0.1? I installed the 07 July Update, rooted, and installed joying tools 1.3 apk with some no kill mods, etc.

It hasn't worked on me with Samsung Evo Plus 128GB SDXC, but this one has:

I just need to get down to the car to verify. :)
[FYT Android Head Units] dyabolikarl:
Hi I setup that today but unfortunately my unit is running perfectly. So my speed difference was only 0.8km/hr which is within specs for my odb.
[FYT Android Head Units] Clandaries:
It is not the speed difference we are talking about :)

We are talking about the steps. it goes 0 - 4 - 8 - 12 and so on.

But it should go 1 - 2 - 3 - 4 and so on :)

[FYT Android Head Units] dyabolikarl:
I'll check i am sure mine doesn't do that.

Reported the GPS issue to Joying today, too. Mine is also jumping in 3 to 4 km/h steps. Also, GPS reception with update from7th July is worse than 25th of May. My navigation software is permanently recalculating, which makes the use of the software senseless.
[FYT Android Head Units] dyabolikarl:
Well I made a video. I was going to do a screen record.... but when i logged into play store my unit crashed and factory reset :( So i had to get the ying up and running again :(

Near the end of the video you can see the jumps when i hold the speed then slow down and speed up about 17-20seconds in (left is GPS , OBD is right)

Sorry if it's not good enough :(

[YOUTUBE]hCt1r1UxELg[/YOUTUBE]

I'll do another one once i sent my joying up again. I have screen recorder installed now.
[FYT Android Head Units] tbd@immigrantsong.de:
Have you checked the GPSsettings in the car settings and the location settings? I had to disable GLONASS and "high accuracy" as my Navigations was also continuously recalculating.
[FYT Android Head Units] gtxaspec:
How do you disable glonas?
[FYT Android Head Units] spinbot:
The issue with speed stepping up in jumps is because they are using integer meters per second.

So it will increment every 3.6km/h or 2.24miles/h. The Waze GPS shows rounded speeds so it jumps about every 4km/h. This is a real pain as I use it for over speed alerts.

Not sure what has to happen but I am assuming that the gps driver needs to be fixed to return fractional m/s (as a Float not an Integer).
[FYT Android Head Units] Guangor:
Good night, after updating to the July 7th version the GPS does not find satelites and it fails quite and the phone is disconnected from the Bluetooth constantly ...

Is there a solution to this?

Thanks
[FYT Android Head Units] edit:
I did not have any issues with the GPS after upgrading from 25 May to 7July but I had issues with Bluetooth and I found out that it depends a lot on the phones used.... I found out that it liked my Samsung a lot better than my Huawei.

Please write an email to Joying... the more we all write the bigger the chance that they will take action and fix the issues.

---------- Post added at 06:31 AM ---------- Previous post was at 06:24 AM ----------

I wrote to Joying many, many emails on this subject because it bothers me a lot. I used to pay attention to the "ding" that Waze makes when I am over the speed limit... it saved me a few times from not paying attention and slowly speeding up. They told me that was the only one complaining and they said that they can't do much about it.... this is how the system works and they can't do anything. Unless we all ask for a fix it will never happen but I guess not many are bothered by this issue so no one asked for a fix but me.

I hope someone with programming skills can fix this because I don't think J will take action on this matter.

---------- Post added at 06:47 AM ---------- Previous post was at 06:31 AM ----------

Bluetooth tethering speeds will always be slower then Wi-Fi because that's the limitation of the Bluetooth technology.

Unfortunately the Bluetooth speeds were cut in half on android 6 compared to android 5.... most likely from poor programming... can't explain it otherwise... and there is no solution yet.... like I said many times... we don't have skilled people to fix it :(
[FYT Android Head Units] Guangor:
Thanks for the answer ... I've already written to joying and I'm waiting for an answer, the truth is that the GPS was going perfect and since I update it, I lose a signal or directly do not receive it
[FYT Android Head Units] edit:
Also it might be wise to double check if the GPS cable plug has not loosened on the back of the unit and you can check if the cable is ok....

So far 2 GPS antenna cables (the wires inside the cable broke, nothing visible on the outside of the cable) on my units in the last 4 years... from the heat and vibrations and the twisting of the cable.... so anything is possible.

This is not a definitive test because it all depends if the cable is the culprit and how badly damaged it is but you can do the following test : Take an GPS testing software (link below) and check for GPS signal while you slowly and carefully bend the cable in various places... if the GPS signal shows up it means there is a cable problem and you need to change the GPS antenna... it's cheap.

https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=ro

OR :

You can also buy an GPS antenna, plug it in, check if it works... if it still doesn't work you can return it because most likely the antenna is not the issue... if it works keep it, problem solved.

Good luck !
[FYT Android Head Units] edit:
You can also return the unit to defaults (if you haven't done it already)... if it's an software issue an reset to defaults may bring it back to life.... I haven't heard anyone complaining of GPS problems so far but who knows... given the software is not at it's best everything is be possible.

Take the microSD cards and usb sticks out, before reseting the unit to defaults and check for for errors.
[FYT Android Head Units] Guangor:
Ok I will do a reset and I hope it is solved because it is very rare that I lose the signal and before it did not happen and the radio is less than 3 months .. also disconnects from the bluethoot the galaxy S7 continuously and before it did not happen ..

In order to prove what you say and thank you very much for the help

So after getting a replacement motherboard for my Joying, I noticed they sent me one with the 6021 chip. They then also had to send me the display board as the new motherboard didn't work with my old display. Finally got the display board today and booted it up. The 6021 chip/motherboard says it's cpu info is "Intel ATOM QuadCore, GPU3D: Mali-400 MP4, RAM: 2GB DDR3"

Right now, I don't know if it's an upgrade or downgrade... but the gpu seems like a downgrade from the 450 to the 400. :confused:

Anyways, I'm back to Joying after struggling with hardware issues with a MTCD unit.
[FYT Android Head Units] edit:
Welcome back !

---------- Post added at 06:53 PM ---------- Previous post was at 06:48 PM ----------

That is a known problem... Many people complained about BT disconnecting a lot on latest firmware.

There is no fix yet :(

Someone created a fix on another forum... Tested it a little and the stability was so and so for me...
[FYT Android Head Units] AssassinsLament:
Thanks!

Odd, but after updating to the latest firmware, my gpu now says 450 (which said 400 before updating).

there's some slight alterations needed for 6.0.1, I think. It will work but there's different files you need.

[FYT Android Head Units] gustden:
Been away for a bit. I'm on the May 25th release and it is working fine for me. I really have no complaints whatsoever. GPS and bluetooth/tether are working well.

From what I have read here, it sounds like there are BT and GPS issues with the latest release. Is there any advantage to upgrading to the July release?
[FYT Android Head Units] edit:
Wooooow ! Welcome back !

Man, we missed you like crazy ! Not to mention that we also need you like crazy :)

You can finally use Google app and Waze/Google maps voice commands are usable again... also voice search.

I haven't tested it but even velvet.apk might work...

More on the 7th July update : BT is disconnecting a lot for no apparent reason. There are times when the CPU usage is high without an apparent reason because the unit is idling.

GPS was fine for me but one thing that drives me nuts if the way the speed jumps in 3.6 km/h increments.... that is old news and I know that I am asking a lot here from day 1 of your arrival but maybe you can have a look at it.

If you fix it you would make a lot of users very happy!
[FYT Android Head Units] gtxaspec:
Maybe this is specific to the 6021 units? I'm on the July release on 5009 and everything is solid, except for GPS step. Best release so far, stability wise.
[FYT Android Head Units] rknuette:
No, I've got a 5009 and have the same issues.
[FYT Android Head Units] Beatwolf:
This may be a stupid question, and I'm sorry if the solutio is obvious, but how the hell can I reboot the HU? So far i've had to disable the hibernate option in order to reboot the system. Isn't there a way to do a hard or soft reboot?
[FYT Android Head Units] rknuette:
Your device should have a hole labelled "rst" meaning "reset". Press it with a tooth pick.

The other way which should work on your device is sliding down the screen two times (1st: notifications, 2nd: an extra menue with options like reboot).

I'm missing time information in the Bluetooth music app.

I mostly use it for audio books, where total duration and current progress/time remaining is essential.

I do not want to move the audio books from my phone, since I spend most of the time listening in other vehicles than my own car.
[FYT Android Head Units] Rated RR:
For couple of times Joying support has told me that if you press reset switch you will lose all your user data. But I'm not too sure about that, and i don't want to try it now that i finally brought my system up and working with the July upgrade.

This is true, though, if you haven't done default settings on upgrade, but then you also have all sorts of problems.

Anyone has tried that on a system that is working well?

A very quick mini review on the Joying Sofia 2gb 7" single DIN with integrated amp (DE-JY-UMS03N2).

Positives...

+ Android 6.0.1 out of the box; no upgrading required.

+ Simple physical install and mostly straight forward software setup.

+ Paired with my ELM327 OBD2 bluetooth scanner straight away (not the Joying one) and works well with Torque Pro

+ Google Maps and other GPS dependent apps worked immediately

+/- Paired with my Google Pixel XL without any issues, receives bluetooth calls but stutters with music.

+ Loaded up a 32gb microSD card with MP3's and plays fine once i'd installed PowerAMP.

+ NooElec Nano 3 USB SDR (bought from eBay) installed easily, drivers and Wavesink Plus app (purchased on Google Play) gives FM & DAB+ radio

+ Sound quality without Viper4Android is passable but not brilliant compared to my previous high-end Pioneer HU. Must give V4A a try.

+ ADB over WiFi was easy enough to set up with the all-in-one app. Got root no problems.

+ / - Bluetooth data connection to my Pixel is a little unreliable.

Now for the negatives...

- Ribbon cable to screen was (and is) loose causing the display to cut out. Had to disassemble the unit and press the cable ends back together.

- Had to reset the unit more times than i can remember whilst getting everything up and running. Random issues.

- Having to type in security codes to access settings menus is a PITA when you keep forgetting them.

- Bluetooth music streaming stutters and is therefore useless. Reverted to SD card as a work around.

- Installed Google Now Launcher as i couldn't stand the Joying one! Ok Google worked, then stopped working. Need to investigate.

Things i'm yet to try out...

- Viper 4 Android to improve the sound quality

- Bluetooth steering wheel remote (attempting to use the touchscreen in a stiffly sprung sports car is challenging / dangerous)

Overall, i can't really say if it's better or worse than other Joying or even Android headunits as this is my first but it shows great promise and the negatives haven't made me rip it out of the dash yet.
[FYT Android Head Units] surfer63:
Thanks for your review. Especially your remark about the SDR triggered me.

I had no idea what an SDR is. Now I do. :)

Going to have a look at it.

Edit: Or are the DAB+ dongles actually also SDRs? Are they somehow restricted?

Does anyone know what Chip is used to drive the RCA Line outputs ? I need to know for isolation transformer selection to drive the balanced inputs on my Harmon Kardon door amplifiers in my old P38 Range Rover. I already tried one channel via a balancing transformer, and the difference is amazing. All the buzz & hum was gone, so gonna buy 5 transformers, but want to make sure they match the RCA output impedance.

My unit sometimes in the past randomly couldn't boot, i thought it was the cables and i unplugged everything and connect it back together, sometimes this solved my problem some others it worked again after some hours. All these times the buttons lit and the screen was blank with no sound or touch response.

Yesterday when i closed my car everything worked fine but after an hour when i turned it up again i faced the same problem, i unplugged the unit in order to plug it to my psu home to see if it will work and the problem still persists (this is happening for the first time), after that it boot and after 20-30 seconds it closes again. From that time i have not manage to get past that point even though i tried to unplugged and plug again the main cabletape that connects the unit to the touch screen.

Hello, has anyone facing this issue with his device?

BT Dialing.

Hi, when I download my Contact list from my phone with the default BT app, the numbers are all without the International + sign so they will not work. Have to ad a + or a 0 in front to be able to call? Any workaround for this? Strange for me that I can't fined any other complains for this. I know I can change the + in my mobile with 0's, but some countries use only 1 zero, others 2 zero's. With + it not an issue on the Mobile, just that + get lost when you download your contacts from Mobile to HU.

Thanks
[FYT Android Head Units] pwood999:
Same here, but considering the July update, although not suffering the bug that release is supposed to fix.

I'm also using PowerAmp full version, and EQ seems fine, so not bothering with Viper.

I'm using eBay non-SDR DAB+ USB. Was really crap with windscreen antenna, but since making my own "DIY Coax" antenna and installing on rear window it now works with 5-bars 99% of the time.

Most threads about audio quality seem to focus on the power amp chip. My 18 year old Range Rover Harmon Kardon door amplifiers fed from the RCA outputs seem to give really good audio.

Same issue for me. I took the cable out and squeezed the IDC connectors in a vice. Now it works perfectly, but considering ordering the longer cable with looks better quality in the Joying Videos.

Not had these problems myself.

As above, not bothering with Viper, but my analog steering buttons work perfectly.

is it better than umecity ?
[FYT Android Head Units] shanetrainST:
SDR's are very handy as some chips sets can operate out of the standard TV and FM, so u can use them for receiving HAM radio bands and Aircraft bands ect.

There is quite a lots of information on

http://sdr-radio.com about these devices.

But if u have lots of Trucks on the road, good chance they use UHF (that's that band they use in Australia) and they are a really good source of road traffic information that can be picked up with the correct chips set SDR and a android app (sdrtouch)

also u need to correct antenna to match the frequency bands u want.

tip on how to--sound on radio works but not on music or bt

this might have been covered before but I could not find a reference to it so I thought id post my findings in case someone else benefits from it.

I have a UL 135N2 6.0.1 in a 2011 Nssan Titan with the rocford fosgate system. I I couldn't get the amp to turn on for anything else but the radio and after searching I came upon the joying website that recommends to reload the firmware or re-seat the harness and other useless suggestions. finally the person that had asked the question there, connected the amp-cont wire to the amp turn on wire and that worked but if you have a vehicle specific harness like me the amp remote wire is included in the wiring of the harness and in my case at least think the turn on voltage is 5v so I was a little worried about supplying 12 v that comes out of the amp-cont wire so here is how I fixed it:

go to the factory settings menu right bottom button, enter the password 8863 and configure your can-bus interface. On mine I could not find my exact model but I picked Nissan Patrol and upon downloading the necessary file the amp now turns on for all sources

not sure if this will work for everyone and there is some caution on downloading the wrong interface file but might worth a shot

Where did you locate your GPS antenna? Did you check for breakages in the cable? If you twist the cable very gentle on several postions: does it change the signal?

Positioning the antenna on top of something metal helps increase the signal. I have my GPS antenna inside my dashboard on top of the big metal bar. The GPS head is magnetic
[FYT Android Head Units] Guangor:
Thanks, I'll check everything
[FYT Android Head Units] surfer63:
Also check if you are using A-GPS. A-GPS use mobile phone masts/signals and WiFi. In case of connection to a WiFi network it can use it for a first 50 mtr course positioning. If you leave home and you are connected to your WiFi, you should get an almost immediate position.

As your head unit does not have a SIM, unless you have a dongle, it can only use the WiFi signal of a network it is connected to.
[FYT Android Head Units] Guangor:
A-GPS connects when you are in a WiFi network or you have to activate it somewhere?
[FYT Android Head Units] surfer63:
You have to enable it in your GPS/Location settings.

Update on RCA Line Outputs & external amplifier buzz. Mine is now sorted, and sounds much better.

I have used 5 of these 600ohm balancing transformers to connect the Joying line outputs to the Harmon Kardon audio amps in my old P38 range rover. These both isolate the amps from ground loops, and provide a balanced audio feed to the amps.

Now the speakers are silent when the head-unit volume is down, and loud & clear when listening to anything from the stereo.

[FYT Android Head Units] treel:
Not exactly sure what do you mean.

Bluetooth works like a client server. The device which initialize the connect first time must enter the pairing code.

When you connect something like OBD the head unit is the server which provide the code.

If you pair a phone with the head unit the server is the phone.

Which device you are trying to pair ?

[FYT Android Head Units] treel:
OK I have made a short video with the pairing some OBD but it should work the same.

I need to know if you the device require a pairing code or not.

If you don't know try to pair with a phone a and if it require code the phone will ask for it if not it should pair with out the code request.

if it require code then the choice is yours and you can enter whatever you like . (maybe there is a problem with a pairing then watch the video and follow the steps)

if the pairing don't require code then you need enter 3368
