yeah on my phone it says the card is formatted Fat32 but it doesn't show up in the unit on either card slot.

Have you tried this on the January 4 update? I just got the unit and I'm scared to try and root it on the new update.
[MTCD Android Head Units General] wanb1i:
No, it's just a UI update and I'm not using their UI.

No worries, the units come rooted, this just opens it up and installs SuperSU to keep it permanent.
[MTCD Android Head Units General] braddman:
So it's safe to do this on the Jan 4 update?
[MTCD Android Head Units General] wanb1i:
Yes, it'll be fine.
[MTCD Android Head Units General] braddman:
Kind of confused about the instructions earlier, you gave me one file, then I believe you added another one later a couple posts down, is that correct?
[MTCD Android Head Units General] wanb1i:
Yes, that's right.
[MTCD Android Head Units General] sonof:
Anyone have root with the latest drivers and bootimage etc. That come with January 4th (or December) update?

Also did someone modify the non-functioning DVD and Eject buttons to work?

[MTCD Android Head Units General] braddman:
I think there's a step missing for idiots lol. Do I have to install ADB for windows?

Second question for idiots, is this made to install from a USB stick on the unit? I copied the files to the USB stick but on the unit I can't see anything inside the USB stick and I have no idea why.
[MTCD Android Head Units General] wanb1i:
No adb on windows required, when you click on the bat file itll open a terminal window where you enter the commands. Yes, USB on the HU. There are 2 USB on the unit, be sure to modify the commands for the usb you are usinng. How did you format the USB? I'm pretty sure it needs to be fat32. The HU won't read any other format.
[MTCD Android Head Units General] braddman:
I thought this was done from the PC side? What's the IP address used for if everything is done on the HU?

This part of the instructions confused me...

o to PC open the ADB_FOR_PC folder double click on OPEN_Command_Here.bat and copy - paste commands in the file attached. Sounds like a long process, but reall takes less than 5 minutes.

Here's where I am.

I have the USB stick in the HU being recognized and all the files on it including the one called cmd_file.txt and it has my IP address on it. What did I do wrong?

You keep mentioning BAT file, what BAT file? I'm confused about the ADBFORPC folder thing.
[MTCD Android Head Units General] wanb1i:
So, the ADB_FOR_PC folder goes on your PC (not the HU). Click on the open_command_here.bat file and it will open a terminal window on your PC. Now open the Cmd_file.txt and edit the commands to the disk0 or disk1 of the USB in the HU and the ip address of the HU on your network. Then copy & paste the commands, in order, and hit enter for each and your unit will be permanently rooted.

Be sure you have installed alll the updates or you'll have to do this again.
[MTCD Android Head Units General] braddman:
I found it...I redownloaded the zip and BAM...it's in there. SO dumb...sorry.
[MTCD Android Head Units General] wanb1i:
Are attached.
[MTCD Android Head Units General] braddman:
Do I need now to install SuperSU?
[MTCD Android Head Units General] wanb1i:
Just run the commands, if, after you reboot, supersu isn't in your app list, then you can install supersu. You may need to update the su binaries.
[MTCD Android Head Units General] braddman:
Done and Done, have you installed speech? I was wondering how to get turn by turn speech on google maps.

Nevermind I guess it just works.

The 12/8 update fixed that ,mine works fine .ok Google doesn't talk back but maps works fine if you select it s the default Navi app.
[MTCD Android Head Units General] thedru13:
So having an odd issue. Not sure if it's a headunit thing or playstore. So I can download free apps fine. When I try and buy an app via the headunit it errors out due to payment.

This would allow a fast and stable connection using an android smartphone through USB tethering, while charging the phone at the same time.

The details are in the joying forum:

Hi all, I have problem with rear speakers. There is no sound coming at all from rear speakers and I don't think it ever was. Unit is 2 days old and I found out today. Any idea what might be wrong? Is it an issue with amplifier? I thought I didn't have any as I saw under passenger seat and there was no amplifier box.

Car model : VW Passat 2012 B7

Unit : Joying VL 131N2

Please help!!
[MTCD Android Head Units General] wanb1i:
Did they work with the old hu? Are they connected? Use a Volt meter to test the wires at the hu for power output. First test the front working speakers for a baseline reading, then test the rear. Make sure you have a good ground on the black wire. If there's no output, get a rma & send the unit back.

---------- Post added at 07:50 AM ---------- Previous post was at 07:47 AM ----------

Why do we need this? Wifi tethering works great.
[MTCD Android Head Units General] DarkFoxDK:
It doesn't seem like you can move the screen in that one. My car has climate controls right above the radio, so the screen can't extend much above the unit. Hence why I'm interested in Joying's system.

[MTCD Android Head Units General] DarkFoxDK:
That's the 1 GB version. Unless they wrote the wrong specs. ;) (Edit: Which I'm not entirely sure they haven't, btw...)
[MTCD Android Head Units General] wanb1i:
I'm new to these head units, and I just bought a Joing 10.1 5.1 Android unit w/1gig. I may be able to cancel it. Is there a serious issue that I should cancel it?
[MTCD Android Head Units General] DarkFoxDK:
The problem with only 1 gig of memory, is that you'll be able to run at most one, maybe two apps in the background before running out of memory, and then Android starts killing apps to save memory. For example, this means your music might just randomly stop, because Google Maps used too much memory.
[MTCD Android Head Units General] wanb1i:
Understood, I watched several videos, but none of them showed any or little multitasking.

I cancelled the order!

Hi [MENTION=425896]kc2koj@hotmail.com[/MENTION]

Are you able to connect to the web via bluetooth tether thru your phone instead of wifi hotspot? This would really save a lot of juice on the phone. Appreciate your feedback. Thanks.
[MTCD Android Head Units General] ikerg:
I don't think it could be possible... MTCD units (like joying) controls the Bluetooth from the MCU and not from Android....and they are limited the Bluetooth profiles to be used

[MTCD Android Head Units General] leonkernan:
Joying really would like you to buy an upgraded headunit.

They've even got an idea for how to use the old one, as a fancy radio in the house?!

[MTCD Android Head Units General] dayanandgp:
They were working with OEM Head unit.

How do I test the voltage at headunit? Do I need to cut the cables to check?

Any other way to find out what's wrong? :confused:
[MTCD Android Head Units General] wanb1i:
No, no need to cut the cables. On top of the HU is a diagram showing which wires do what. Find the appropriate + wire, put the red probe in the corresponding hole of that wire in the plug connector until it makes contact, make sure the black wire is connected to a good ground or the associated - wire. Read the meter, really quite simple. Make sure music is playing.
[MTCD Android Head Units General] dayanandgp:
Thank you so much for your replies. Are you talking about RR and RL out pins in the picture?
[MTCD Android Head Units General] wanb1i:
Ok, odd, i don't have those problems with my phone. Also, not sure you'll get much of a charge out of the HU, maybe, half an amp? That might maintain your state of charge.

---------- Post added at 08:19 AM ---------- Previous post was at 08:13 AM ----------

Yes, trace that wire to the plug that connects to your car connector and test it there. Test the front first so you know what it should read.
[MTCD Android Head Units General] dayanandgp:
Please bear with me... I got a VW connector and it directly connect to the OEM plug. So the 12V and all wires are part of the connector plug... So how can I check the individual leads? I was actually talking about the RR and RL on the left side of the picture where it is going to " Monitor (B) ".

Which one did you mean?
[MTCD Android Head Units General] wanb1i:
So, where the wire enters the plug, if you look closely, you wil see a metal connection to the wire inside the plug. Put the red probe point on the metal of the + cable and the black one on the - cable. With the meter set to DC volts, read the meter.
[MTCD Android Head Units General] dayanandgp:
Okies, thanks I will get hold of a voltmeter and try..
[MTCD Android Head Units General] wanb1i:
Better to get a digital meter if you're going to buy it, more accurate, but an analog will work as well.
[MTCD Android Head Units General] Pinkpanther9:
I would first look if there are speakers connected to the outputs. Disconnect the big black plug from the HU. Then check with an ohm-meter or DMM the resistance between the green and green/black wires. You should read something like 4 or maybe 8 ohm, on weird wired cars you can also get something like 2 or maybe 16 ohm. Do the same test on the purple and purple/black wires. If not in this range you don't have speakers connected there and you need to check why.

I don't think anyone released a modified APK for DVD and Eject buttons? I have been following the thread and read every post in it. There were talks about it being possible but newbies like me don't know how to do it even if pointed at the right direction. It is the Sofia-1-C9-Server-V1.0.apk that handles it and user gtxaspec found out about how it works here but I don't think he released a modified APK.

And what comes to the root the boot.img in root_AIO.zip is - as far as I know - from the older update file but I don't think that makes any difference :) Thanks for the link, enabling root was easy with it. I used MicroSD card instead of USB stick but just had to alter the commands and it was done.

3g dongle

Hello

So I have this unit and it runs like a dream, but now I want to connect it to a 3g dongle. I ordered the Pumpkin 3G dongle because it seemed android friendly, and tested it works on my computer, but the head unit doesn't find it. Does anyone have experience with this?

Short update : since yesterday night situation got worse and sound was coming only from front right. Whenever I pressed the unit sound was coming in front right and left still not In rear. Today morning I removed the unit and replaced with OEM and rear speaker was working. So I replaced the unit and pressed the plug little harder thinking it might be some loose connection. The rear space is pretty cramped in passat headuinit so I am guessing one of the wire was twisted and or loose when I shoved all wires. I will drive around for few days to see if problem comes back and if it does I will return it.

At this point I have one question, while routing the USB cable to Glove box, one of the USB cable got frayed /spliced and I had to put a tape around it. Do you think I can still return the unit or will they create problems? :crying:

Solution to too bright screen

Root and install Cf.Lumen from Play Store.

You can either let it dim the screen based on sunset and sunrise or time.

Update location to your location in the app to use sunset to dim the screen. Select Custom as sundown filter. Select 0.200 value to each of the three RGB channels. This will dim the screen nicely without affecting the screen color too much. It will look a little washed out due to the back screen light still being too bright but that's something we cannot change at the moment.

If you want it to dim based on time set sundown filter to none and use the above settings for sleep filter. Adjust sleep time to begin for example at 8 p.m. and after that time the screen will be dimmed.

Experiment with the settings of Cf.Lumen and find out what looks best for you. There's even the possibility to only use Red channel in the night which is good for your vision in the darkness etc.

Does it work even after sleep??

I'm using Twilight for the same purpose but it is disabled on each sleep so I have to launch it every time.
[MTCD Android Head Units General] sonof:
Unfortunately I don't know at the moment as I just tried it the first time today. Could the solution be installing the app in the priv-app folder to prevent it from being disabled on sleep?

Edit: Yes, installing as priv-app prevents the app from being disabled on sleep. However, the apps notification bar disappears after sleep but the app is still running in the background doing its magic.

Alright last question, is your dongle working via tethering? Or does it setup a wifi connection that you connect to? I have a sinking feeling the Pumpkin Dongle is not compatible, after reboot still doesn't work.

To answer your question, my dongle works by plugging it into the USB.

[MTCD Android Head Units General] Kurt Lund:
[MENTION=2856632]wanb1i[/MENTION] what dongle is that? I assume some labeled Huawei or something. I have now tried 3 different dongles and none of the work. Does you use PPP or something or did it work out of the box?

Another question: when I turn the ignition off the radio does not shut down. It is fitted into a Skoda which is technically equal to VW Golf. In the manual it says something about cutting the orange wire. Should I do that? I tried to unplug the red acc wire and the it shuts down immediately. In car media setting I have tried both opff and dormancy, but it does not make any difference. Isn't there a menu for the dormancy timing. I think I saw it somewhere, but now I can't find it again. Can somebody give me a hint. Thank you in advance.

Question one : its a Verizon 4g LTE dongle like this:

http://www.ebay.com/itm/Novatel-Wir...614670?hash=item2cb8d652ce:g:3RoAAOSwA3dYfFLV

It connects and directly provides high speed 4g Internet access when available and lower speed 3g when 4g isn't available.

2nd question: The unit stays on for about 30 minutes in "sleep" mode so if you stop for gas or whatever, you don't have to wait for it to boot up. I've had mine installed since November and haven't had any issues with the battery.

I've heard people say there's a way to change the dormancy timer, but I've never been able to find it.

Some newer cars don't turn off the acc until the driver door is opened, have you checked that?

If that's not it, ask the vw dealer why the acc doesn't turn off with the key. There may be a way to reprogram it.
[MTCD Android Head Units General] Kurt Lund:
I figured out why it did not turn off after the key was taken out. It says on the ACC cable that the ACC cable should not be connected on "High configuration cars" apparently my car is such a car. Actually I could see on my old car radio that the red ACC cable was not even included in the cable harness.
