I guess the "reverse in" wire detects +12Volts . By means of trial disconnect the wire and make sure it has ground signal. If problems persist, there will be something wrong with the electronics that check for the 12Volts.

It's been a while since I installed the stereo but I thought the reverse in wire (called Reversing Wire on my manual) was used by the rear camera to power/enable it? I'll check it anyway to see if it's not taped up correctly. The only wire I've got going to the reverse camera is the video in, the camera is powered off the rear reverse lights on the trunklid.
[MTCB Android Head Units Q&A] IrishHayZeus:
In the Factory Settings (Password 126), there should be an "Audio" screen, that lets you adjust the mixer levels between the radio, bluetooth audio, dvd, tv, avin, and android (sys). Adjust these until you have satisfactory audio levels between the various inputs. Be careful though, don't go messing with stuff in other screens that you don't understand. You can brick your stereo.

Hi Henrik

Did you put the sd card in the gps slot? If you cant get it to register it from there, then just go in to recovery and install.
[MTCB Android Head Units Q&A] IrishHayZeus:
The Reverse In wire on the HU is a detection wire, that looks for +12v on the wire to signal that the car is in reverse. In my car (I just bought a Pumpkin JY about a week ago, and I installed the rear-camera last night), exactly like yours, the camera is powered from a splice in the +12v wire the powers the reverse lights in the trunk. However, you still need to connect the "Reverse In" on the back of the HU to a matching wire that indicates when the car is in Reverse. Some units will auto-detect the video signal from the camera and switch automatically, but most, in my experience, require an active +12v signal from the dash/console. In this way, its actually possible to have the camera powered all the time, and hard-wire a switch on the dash to force the HU to switch to the camera while driving (I'm considering this for when I tow my boat).

Cheers,

Is it not possible to let for example Deezer or spotify use external SD in the KitKat roms? After a reboot or app restart i get the message that the location cannot be accessed. Same goes for my Sygic app (purchased) It cannot see any map on the external sd card.

Is there a fix?
[MTCB Android Head Units Q&A] lmattiso:
Great information, thanks. I wonder if I ground the reverse in wire if that will still allow the video to trigger the head unit. Either way I'm going to check out the wiring harness and ground that signal. Thanks for the tip.
[MTCB Android Head Units Q&A] agentdr8:
Just be sure to diode-isolate your 12V source, as to not provide power to the reverse lights while driving forward :D

noise

1Hi [MENTION=3590033]Malaysk[/MENTION]

I installed this firmware on my jy unit and it installed fine, really cool looking. But I am getting a noise that sounds like a a hard drive running coming from the speakers, it makes the noise even with the volume muted.

Thanks

I managed to update my unit, with new MCU and Android version, I choose to use your newest for 1024 resolution and it works very well! I have some questions for you thou, what navigation software do you recommend. Also in the OEM application I used to have an application that I could streem music/video from my phone to my unit, this seems to be missing in oem.

I have tried to install Here (Nokia) on my unit, but I can't get the settings menu to show so I can't choose the external sd card to save maps. Anyone else who found a solution for this?
[MTCB Android Head Units Q&A] gy_ro:
I only told to connect that wire to ground to test and see if you got that "no signal" text while that wire was grounded (HU switching to reverse cam). If not, the electronics are ok, if the HU keeps switching to reverse cam while the wire is connected to ground, the 12V detection circuit is damaged.

Normally the 'reverse in' wire is connected to a switch which gives you 12V when you put your car in reverse.

Where you get the 12V for your reverse cam itself is your choice. I always drive with day running lights on (but my car has the taillights on too ...), so I connected the cam to the taillights because that was the most obvious and easy way ...

Hope that I explained without confusing you now.

Ronny.

Hi Malaysk !

Tell me regular launcher is oem from kgl or kld ?

[MTCB Android Head Units Q&A] Enc0der:
Same here, yahoo weather never worked for me.

I think this is because of the screen resolution, this app has no landscape mode (I tried it on the phone, it won't rotate) so I believe this is what causing it to crash at start up.
[MTCB Android Head Units Q&A] typos1:
The person I am talking about did a lot of research about the radio chip and found there were different ways of implementing AF, they were talking about maybe trying to change the way the app does it.

:)

The line is common on Android launchers of all types, it indicates which dekstop screen you are on.

There are several schematics for that sort of thing in this thread

We know they are the same but they are NOT interchangeable.

---------- Post added at 11:35 AM ---------- Previous post was at 11:25 AM ----------

Thats what usually happens if you put the wrong MCU on your unit, are you sure you are using the correct one ? If you are it may be a bug or possibly someone has incorrectly named the MCU.

There are no changelogs for firmware.

It can be hard to search - you have to think of all the words people might use to describe something.

[MTCB Android Head Units Q&A] SinergyX:
I installed this radio last night, noticed my car has no reverse 12v by default. Now i could get a line from the rear light or do a switch, but i noticed there is a 'car record' program that i gues is used for 2nd video in? So my idea was to put my rear cam to the 'cam 2 in' of the radio and use the 'car record' program to get a video signal. So i have control over my input (since reverse deactivate when u put your car back in 1 - if you are bad at reverse parking - thus loosing signal) and can launch it at any given time (and offcourse, record stuff as i go). Also, since its just an android app, allowed me to continue use my HU with no issues.
[MTCB Android Head Units Q&A] Malaysk:
Navigation software can not recommend, because in Russia we used the program that you do not fit. Navitel, IGO , Yandex Navigation and others. Other questions I unfortunately do not understand. ;)

No need, I ve put ALL firmware on the fileserver linked to on the first page ! :)

I wasnt in contact with anyone, I said someone posted about it before and they found out quite a bit of info, I know they were Italian and I m pretty sure that it was this year, so if you wanna find the posts I d use the search function to the right, search "AF" going back as far as 01/01/15.

Already is Malaysk - everytime DSA uploads firmware, I put it on the fileserver linked to on the first page, coudu puts his there as well, only yours is missing, I can upload them as well if you want ?

Hi,

I'm using a DVB-T USB dongle with the PadTV app (it's the only app that detect my dongle, other apps including PadTV HD from the same developer does not detect my device).

It works very well and makes my dedicated DVB-T tuner irrelevant because I much prefer this solution with touch screen controls.

However there are one issue that annoys me:

Every time I boot my unit, Android detects my dongle and then automatically loads the PadTV app - so basically it's like having the app autoload with android on top of everything else.

Is there a way to avoid this from happening? I know I can simply unplug the dongle and only plug it when needed, but it sits in the glove box and I would like to avoid this solution if possible.

There is an app called Autorun Manager that might do the trick, but I'm afraid the PadTV app is not really autostarting "at boot time" but instead simply auto loads itself when the USB dongle is detected...

I will try it and update here, but in the meantime if you know anything that might help I would love to hear :)

thanks

EDIT: the Advanced Mode of this app looked promising, but unfortunately the PadTV app is not listed at all in the list of apps "which are registered for system-wide events".

Black Screen when headlights turn on/off

Hey guys, I have the G2110z with the latest firmware 4.4.4. Everything works well, but I have a slight problem when I turn my headlights on or off. The issue is that when I turn my headlights on, the screen goes completely black but the touch screen/buttons are still functional. The only way to turn the screen back on is either restarting the device or I hold down the statusbar to change the brightness ( Have gravitybox installed). Only happened recently so I'm not entirely sure what I've changed. Anyone got any ideas on how to fix this? If not I might do a factory reset to see if it might solve the problem.

[MTCB Android Head Units Q&A] Henrik_Nyberg:
Have you tried Here? It's a free navigation software from nokia, They provide free offline maps poi speed cameras etc. However for some reason you can not se the settings screen.

But if I was to use another navigation software, what version would you recommend that works as it should with your software. I can get Europe maps instead of the Russian maps :).

I was also asking about someway to stream movies and music from my phone to the Car entertainment system. I used to have an app that was located in the "oem" folder and updated sometimes. If I had the car stereo in wifi teathering and connected my phone to it I was able to stream video and audio from my phone to the car enterainment system.

which verson of MCU?
[MTCB Android Head Units Q&A] Enc0der:
Go to settings -> system (I think) -> clock.

Then, change its color........ I missed it too because it's black on black by default..

But I have also installed the latest 3066 version and I have a different problem - I really don't want the weather panel (constant notification), but I can't remove it...

settings -> system -> weather panel -> always crashes with force close.....

I have tried all possible settings for the GPS location method if that should make any difference..

What you have stood on the factory firmware MCU? To KGL there are different versions KGL/KGL4/KGL5/KGL3 you need to flash MCU only under the right your unit, or you will work incorrectly button!!

MY OPINIONS:

My favourite GPS app was Sygic, I purchased it a couple of years ago. However, a recent update made it stop working with my head unit and their support confirmed there was an issue between my hu and Sygic. I do keep trying every so often though to see if it's been fixed (it hasn't).

I tried several offline ones on the Play Store (Here, Navmii, Copilot, Route 66, several others) and although they all have something good about them I eventually found my original install of iGo (was on an SD card from my hu seller) and after some updating/hacking I am using that and am happy with it.
[MTCB Android Head Units Q&A] zorantoma:
Ha?????????

Please read the tread first and what people are talking about. True contacts hase nothing to do with this.
[MTCB Android Head Units Q&A] gnox:
As far as I understand it - the ROM has True Contacts installed - and this app takes over the reading of contact data from your phone and passing the data to the MCU Bluetooth stack

Behringer USB DAC

I had the same issue when Xposed Screen Filter was installed.

USB DAC

I searched and found one or two members tried/use USB DAC with the HU. I found the Behringer UCA222 what could be an inexpensive solution for sound quality problems. BUT USB DAC works on Android side only. So no Radio, no BT (and others what I don't care). If would be there an USB BT dongle what can handle handsfree over Android (TrueContacts works this way?) and an USB FM/DAB with good and usable interface (RTL2832U+Wavesink is ugly, Monkeyboard is expensive) then I would give a chance for an USB DAC.
