[MTCB Android Head Units Q&A] TooBusy:
Since I bought the camera for my PC, I tested it on my HU only to see how it works; no intention to leave the camera there; I have two dedicated dash cams in my car. During the test, I never had any force-closes. I didn't try using other apps while recording. I forgot to mention sound: every few (about 5) seconds I heard loud noise when watching recorded videos. This was actually recorded on the video, but not heard while recording. All recoded videos had this noise.

Dear Developer,

does your app get acceleration via the accelerometer or via the gps?

I'm trying to understand if autosave can work on a device without accelerometer.

Thanks a lot and best regards

Does this unit lag at all for navigation?

Is the quad core version better value?

Dear,

I see the pixel, too.

So it's by dialyroads?

This is not a big problem, but did you find any fixes?

Hi

Have you a idea ?

I Have 2 cams connected: one on the reverse and it's ok , I can reverse the picture as I want...

and one on the front of my car cennected on the second video input but the picture is INVERSED from left and right... the right is on the left on the screen and the left is on theright ??????

??:p
[MTCB Android Head Units Q&A] devilsoft:
Yes, I think it's a small bug in DailyRoads, which is related to the transparent floating buttons bar.

Maybe [MENTION=3221689]DailyRoads[/MENTION] can help you with how to hide that, as I didn't try much on this yet.
[MTCB Android Head Units Q&A] typos1:
Yes I m sure someone decompiled the software months ago, you ll have to use thread search to find it though.

I dont think these units have accelerometers.

Not noticed any lag, there are no quadcore versions of these units, if you want quadcore (RK3188) there are the Ownice and Newsmy NU3001 units, both have threads on XDA.

Sounds like you have your front cam connected to the rear cam input and that youve also got mirror image/reversed image selected in setttings.

Hi Krisian,

downloaded, renamed and tried to copy it to system/app.

I can't delete the original MTCRadio3.apk and/or copy the new one: I tried with ES File Manager and I got a message saying EROFS, read-only file system

Then I renamed the original file to MTCRadio3.apk.old but, after renaming it back to MTCRadio3.apk I don't have the radio anymore :crying:

Any idea to get the radio back or to install the one with the right PTY names?!?

KLD 2.41 29/1/15 + KK 4.4.4 rooted (Coudu ROM v4.2)

Thanks in advance for your support.

It is not a bug, but an essential element to be able to record video in the background. That pixel is actually the viewfinder :)

---------- Post added at 01:56 PM ---------- Previous post was at 01:52 PM ----------

Auto-retain depends on the g-force threshold you set in the video settings, so it needs an accelerometer to provide the g-force values.
[MTCB Android Head Units Q&A] devilsoft:
Yes, it makes sense then :)

Maybe you can position the pixel at 0,0 , MaxWidth,MaxHeight or somehow outside of the screen ?

it's not a big deal for me, as it doesn't bother me, but maybe other users will love that :)

And what does do this dimmer screen option in xposedmtc?
[MTCB Android Head Units Q&A] devin2:
I didn't think beaucause I have the signal reverse ok and when I reverse the car it's the good cam selected ( the rear ) ( that's the cam ok )

but when I select the video input ( the forward cam ) the ima is inverted and the mirror reversed option change nothing for this input ( that change only the rear cam ) ????
[MTCB Android Head Units Q&A] patagonia1:
With Malyask ROM you can turn off screen with the button on the top right.
[MTCB Android Head Units Q&A] typos1:
ONLY if you have physical buttons, if you have touch buttons like some JY units, then only the long press/shut down menu option will work, a short press will not turn off the screen, it will turn off the unit and the only way to turn it on again will be to turn off the ignition.
[MTCB Android Head Units Q&A] agentdr8:
Which TWRP image are you using? The one that [MENTION=853627]coudu[/MENTION] provided? It's been working fine on my GS and KGL so far.

I don't know about advantage, but I do like that I can restart my vehicle and not have to wait for the HU to boot up again.

It allows you to override the backlight controls based on either fixed times, or ones automatically calculated via gps location and date. It also has integration with Screen Filter, which is a screen overlay module that can make it even darker, or place a color filter over the screen (much like Twilight or lux).
[MTCB Android Head Units Q&A] DRidilla:
Can you try using Root Explorer, and changing the permission on system/app & mtcradio3.apk to allow writing, then copying over? Also you may need to reboot.
[MTCB Android Head Units Q&A] R4D3N:
I have a KGL unit and with both original KGL and Coudu's KLD firmware it turns my screen off,music keeps playing and It turns back on if I tap the screen or press any button.
[MTCB Android Head Units Q&A] typos1:
Ah, right, so far I have only heard of it working on KLD units, good to hear it works on others, mine actually stopped working on 4.4.2.

It IS annoying that the screen comes back on if you press vol-, vol+ or mute though !

BTW, if anyone is interested I have a single tuner, internal DVB-T card for Klydes available, pm me if interested.

Hi guys

Hi have some issues with my device

It's a native 4.2.2 1024x600 huifei device for citroen c4

I tried to root it with Download Root Master 2.1.1 so i lost the connection during the process and now the unity is unable to connect to any type of network wifi, 3g, or bluetooth.

How can i solve this problem

doing a factory reset?

Flashing a new firmware?

all tips are welcome

thanks in advice
[MTCB Android Head Units Q&A] DailyRoads:
Unfortunately, there is no easy solution for the capture sounds, since Android doesn't have any special option for developers to control that sound. We had to use a workaround, which doesn't work on all phones. You can try setting that sound level to 0 in the Camera settings, but if this doesn't work, you may need to replace the sound files.
[MTCB Android Head Units Q&A] ESTIMULO:

Are you satisfied with the Dual Core HuiFei? Would you have paid the extra $100 for a Ownice if you didn't have the HuiFei already?

I'm looking at the options here and getting a quadcore unit costs at least $100 USD more... but I'm wondering how useful a quadcore is.
[MTCB Android Head Units Q&A] typos1:
If I was buying now I d be looking seriously at the Newsmy or the Ownice.

Ideally I d like one of the units in this thread upgraded with the quadcore RK3188 chip abecause the MCUs used in them are much more developed than the MCUs used in the Newsmy or Ownice units, it wouldnt be hard to do, but there are no signs of it happening.

I also would want 1024x600 resolution.

The HuiFei type units are good but even a mid range smartphone is quadcore nowadays with a high res screen, so theyre are starting to ook a bit low spec.

It depends what you want to do with it. I do like to have as fast a processor and as much RAM as possible though (my Android phone and Android TV box are quadcore with 2 Gb of RAM and I d kinda like my HU to match them), if youre not so bothered about cores and RAM 2 cores and 1 Gb may be enough for you.
[MTCB Android Head Units Q&A] coolxal:
I'm mainly just looking for navigation, hands free calling, radio, and music. If it can do all those smoothly, I'm kinda fine with it.

What else are you running besides the above that you are starting to run into the limitations of dual core 1 GB RAM?

I also notice there's more of a dev community for this unit.
[MTCB Android Head Units Q&A] typos1:
Some people have said that their units struggle whilst recording video, playing music and navigating all at the same time, but it depends on your POV, if you regard dualcore and 1Gb RAM enough, then these units are for you.

The reason the dev community is bigger for these units is that theyve been around since Nov 2013 and the Ownice and Newsmy only since Sept and Nov 2014, so much newer, the Ownice is not even rooted, but the Newsmy is and theyre making some really cool custom ROMs, however the MCU is a bit underdeveloped (no RDS for instance) and it only has 2 RCA audio outs and no sub out. The Ownice has a better developed MCU (though not as developed as the HuiFei type units) fully functioning RDS, 4 RCA outs and sub out.

Need help with my Eonon head unit

Hello XDA Community,

I'm a long time reader of XDA. I first noticed the Android Head units this past December and thought it was a better and cheaper option than a Pioneer GPS head unit. I recently purchased the Eonon G2110Z

eonon.com/Car-DVD-Players/Android-Car-DVD/G2110Z.html

I picked the Eonon because it comes with a 2 year warranty. All i'm looking for is a music player with GPS and capability of torque.

After reading thru the forums again I felt a bit confused as to if I can upgrade the Eonon G2110Z to KitKat 4.4.x

My unit should arrive from China via Fedex Monday 3/02/15.

Thanks for any help or feedback
[MTCB Android Head Units Q&A] stevenmirabito:
I'm not sure that I agree - reading through the threads for both units just now makes it sound like they are incredibly buggy at the moment, to the point of being unusable in the case of Ownice. The HuiFei platform is much more mature.

---------- Post added at 12:35 AM ---------- Previous post was at 12:31 AM ----------

Just installed the same unit, and yes, it's fully upgradeable to 4.4.4. Instructions are in the OP, click through the spoilers to read them all. I'm assuming based on your link that you purchased the G2110Z and not the G2110ZV, the latter of which comes with 4.4.2 out of the box (and a waste of money since you can upgrade the G2110Z yourself, the unit is identical to the G2110Z otherwise). Also, don't worry about updating the MCU - the Eonon units come with the latest MCU version, v2.40, pre-installed.

Thank you [MENTION=326195]juliocohen[/MENTION]. I didn't get that cable. I thought that connector was not in use, as marked on some pictures I saw before, even though the diagram on the unit shows it as "Rear USB". And even if it was another USB, I thought I wouldn't need it, because of the other two. But I did wonder why I always see USB2 (File Manager or Settings-Storage) and never USB1, and I thought that USB1 was probably for units that have a front USB port.

Your post surprised me. I asked the seller to send me that cable. I hope they send it. My 3G dongle is working, but occasianally it loses connection and I need to wait for a while to get it again. Also, when I have a WiFi connection, even if it's not for Internet, data connection drops off. So far, I would say these are just small annoyances, but it's possible that that (single) USB port is more reliable than the other (double). It might have less issues with other USB devices, such as USB keys, etc, but this might be wishful thinking.

I had the same problem in my 2007 VW Golf,I solved simply disconnetting the red and yellow cable from the connector and using the ones coming from the can-bus decoder.

My requirement to:

-have the head unit support OBD2 over bluetooth and work with Torque App

-The head unit should have 4 preouts (Front and Back Left & Right) and 1 subwoofer RCA + it should produce a good clear sound quality

-The android unit should have the latest android firmware available such as 4.2 or up

-The headunit should have good software/firmware support and updates

-Optionally The head unit should be able to get rooted

Xposed is a framework that lets you make calls to changed code each time a call in the system is made to it. This way instead of trying to decompile/recompile you find the section of code you want to change and you get xposed to intercept it and run your code instead. You can also do this for resources.

Do a search here on XDA - there is plenty of info including tutorials.

Long time lurker...first time poster.

Just installed one of these and have a couple of questions. Before anyone asks, I've read the entire thread. I also got the universal style as I couldn't find one specifically for my vehicle.

I know that I read that there are a few guys here that have this unit hooked up to subs. I also know that some of the other 'similar' android units have fairly standard crossovers for the front/rear/sub based on screenshots posted in various ads on ebay/alibaba/etc.

I can't seem to find them in the menu of the huifei unit I have. Is there a crossover section in these units?

Also, has anyone tried a 64GB microSD card in the unit? I was able to hook up my 1TB portable hard drive to the unit without problems, so I know that there is no technical limits of 32GB on the USB. However, because 64GB MicroSD will be technically SDXC, I was hoping someone could shed some first-hand experience before I go out and buy one.

Thanks
[MTCB Android Head Units Q&A] typos1:
What about modifying it so it runs on the lower half of the screen only, so you can see Torque widgets the same time ? Or does this involve modding the smali as well ?

The 32Gb limit is software defined, pretty sure I ve read a post saying larger cards worked but if they dont then is pretty easy to remove the limit, search xda for details of how to (I cant remember).
[MTCB Android Head Units Q&A] coppertop2000:
Thanks, I'll look into it.

If anyone has any input on the crossover issue, please let me know. I can use the amplifier (5ch) to set crossovers using the amps pot controls, but the sub-level control is really what I'm looking for since my amp doesn't have a remote bass controller, and sub-level often needs adjusting based on input/songs/etc.
[MTCB Android Head Units Q&A] Sengir:
No crossovers,sorry. I adjust my subwoofer amp level from the remote gain knob of the amplificator.

On the unit the only audio settings are: fade,balance,loud,3 bands equalizer.

I could try to make a portrait-skin for running with xposed-Module xMultiWindow.

What is the best solution to get around this limitation?
[MTCB Android Head Units Q&A] TooBusy:
I checked the tread and I couldn't find anything conclusive; not even one post that clearly states "there are issues with 3G dongle with or without a powered hub". Unfortunately, there is not even one post that confirms the opposite: "3G dongle works fine with a powered hub, but there are issues when the dongle is used without a hub". So far, only you are saying that. Too little to be conclusive.

At the moment I'm more interested in "Rear USB" port (#9026[/url). Could it be that it provides more power, or it's in some other way more reliable? If that turns out not to be the case, a powered hub will still have my attention.
