[MTCB Android Head Units Q&A] ftsur:
So I received my unit today. It's a Eonon GA5153. There seems to be two "versions" of this unit. I've been following along in a VW specific forum where a manufacturers rep is interacting with members. When I ordered mine, the ad described an 8" unit that had only buttons and no knobs. There are members who revived this unit. What I and many others revived is a 7" unit with knobs. Rep claims only difference is the knobs. All of the ads on Eonons site and eBay ads show a unit with knobs.

I only hooked it up temporarily, but I was unable to get audio from the car's aux input that is located in my center console. Any know if this possible? My Rockbox,d ipod didn't work with this HUs iPod interface. It's a major disappointment.

Other than that, the unit worked well with my steering controls. It looks nice and ran smooth.

Are you sure the first unit you have pictured is not a KLYDE? I just bought a KLYDE (Pumpkin) KD-C0223 and it is identical to the first picture you showed in your post. Maybe you aren't using the right firmware.

Hmm... Mine's pairing but never asks for the pin...which it needs to function. Trying to get the Vivid Linq working with this beasty. Thanks for your override btw, one step closer to tuning the car from the head unit. Next is getting it to ask for pin, and getting superchips' terrible software to NOT crash when trying to connect to the bluetooth. Maybe some sort of emulation on the android side that translates from the bluetooth app to android's bluetooth controls.

The lights power on for a few seconds when the device boots.

After that its controlled by the can bus.

If you Put 12V on the orange wire, the button lights will keep on.

What app are you using for touch simulation marcros, i tried many? None of them worked properly.

Not sure why you need app settings for IGO, you can do that by tuning sys.txt

Ive got mine installed, ill post some pics tomorrow i hope.

Very satisfied

Canbus works great with VW, only arrow and radio integration in the headsup display don't work.

Any ideas?

The rest is great:

Rear gear

steeringwheel

Airco

I am using Automagic. Just set it to be allowed in Accessibility then you can click anything. Even has an overlay to pick what you want to click :)

What setting do you change in sys.txt to get full screen? or see the whole of the menu?

Ps. I tried to edit the MTCRadio.apk to do my blue radio and it wont load now. Tried just extracting and recompiling the existing one and it wont load. They are protecting these app now in the new image. Just need to work out how :(

[MTCB Android Head Units Q&A] kwalsh24:
So here is a question that just popped into my head.

Since these units do not have a standby mode, how well do they perform after a few power cycles? As essentially when you pull the key its like pulling thw power out of thw unit, so its not having a proper shut down, anyone noticing any ill effects from this ?

I see this unit here

http://dycaion.en.alibaba.com/produ...lti_touch_Screen_3G_Wifi_BT_Radio_Stereo.html

It has what appears to be a 5 day standby? Also uses a a9 1.6, I contacted the supplier to see what chip is truly being used, as you see a lot using the telechips processor. Makes me wonder if this is the same or if its using a legit 1.6ghz processor. Would also need to check the os, one spot says 4.1 another spot 4.2 lol
[MTCB Android Head Units Q&A] getehem:
This unit is a product from SION, also sold by ZHINAVI, with same address in Shenzhen, with a different interface ( see http://xdaforums.com/showthread.php?t=2618348 and....beware)

Thanks for the heads up, will continue with my order on my huifei, if it ever does get processed.

Anyone have anything to report for my first question about the lack of standby effecting performance ?
[MTCB Android Head Units Q&A] brownstein72:
Mine seems to have a large capacitor or something because if my car has been running for a while, the unit says "shutting down" when I turn the car off and then it will stay on for about a minute. I am guessing it does a proper shutdown at this point. Mine is not a huifei branded unit though and seems to have some differences with the software.

This is the unit I bought:

[MTCB Android Head Units Q&A] typos1:
Theres nothing to "beware" of - Telechips are ok, maybe not as good as Rockchip but ok.

The problem with this unit was that the first ones came with a quad core Samsung processor and 2Gb of RAM.

Then they were downgraded to a Telechips dual core and 1 Gb of RAM.

Some people ordered the quad core one and got the dual core, they were not happy, obviously.

But if you KNOW its a dual core Telechips before you order, then there is no problem.
[MTCB Android Head Units Q&A] kwalsh24:
Well, the only problem is, they aren't properly advertising the speed, as some are listed as 1ghz, 1.5ghz, 1.6ghz & 1.7ghz. I keep hoping to find a unit with the knobs and 8" screen with a proper spec processor but no luck lol.

Has anyone had any success remapping any of the buttons? Would make more sense to have a home button over a DVD button on the unit I'm getting.

Hi all, just a few questions regarding the unit I've just bought, I'm wondering if anyone has any experience with this specific model.

"2014 Exclusive Pure Android 4.2.2 1.4G Dual Core 1024x600 IPS Capacitive Screen Car DVD player for AUDI A4 With 16GB Flash" from aliexpress seller Green Point.

Just wondering if it matters much that the processor is only 1.4ghz and if they can still be rooted using the same process as the other units? Final question, is there a SD card size limit? I'm about to go and buy some 64gb cards but the only thing I can find on the thread suggests 32gb is the maximum but that 64gb+ are untested.

Cheers for any help!
[MTCB Android Head Units Q&A] pakidermo5000:
I am glad to hear that you could fix your headunit and that you are back to business !

I do not use automagic, but Tasker. I was trying to figure out how you call the Amplifier settings menu to then send the "touch" order to activate the loud speaker option.

So, I downloaded your file, but it looks empty when I open it with notepad++. And it is only 166B. Could you check that ?

You just gave me the idea for using the radio knob with poweramp (or any player). It can be done with tasker. I just need to find out the coding of the knob button (can get that from getevent in adb), and assign a "touch" on the right place of the screen when the knob button action is detected and the player is on. (not really needed in poweramp as you can swipe to change song..)
[MTCB Android Head Units Q&A] 1-2-Hak:
You right - that didnt up load at all :(

I used tasker for years and then I found Automagic. Blows tasker out of the water. Fully flowchart - easy to implement.

I do things like detect when my phone is connected via bluetooth - make it turn on wifi access and announce car mode activated. The head unit detects my phone wifi and brings up google now to show cards for travel to work etc.

Love proper automation :)

Another thing I have just set up is Xposed Gesture Manager. I have set two finger swipe left an right to change to next app. Two finger swipe up gives app switcher. Three finger pinch closes to home. No more fiddling with buttons soft or hard anymore. You can set up different swipes to activate radio etc as well :)

Will have a look at uploading the flow again tomorrow.
[MTCB Android Head Units Q&A] xrapidx:
Sounds like you guys are happy with the units in general.
[MTCB Android Head Units Q&A] 1-2-Hak:
This is the third Multimedia head unit I have hacked. I can you let you know it is so far the most supported by the manufacturer and customisable I have come across.

I can definitely recommend this unit as it is out of the box for 90% of the users and still have all the customisable options for the hackers out there who love to get the most out of the units.
[MTCB Android Head Units Q&A] pakidermo5000:
:) Looks like we are doing similar things... xDD

I am starting to be "fluent" in tasker.. will give it another shot, but I like the flowcharts of automagic... helps a lot in long tasks...

I also automate turn on wifi hotspot on my phone when bluetooth is connected, and turn off, when disconnected.

I also set up brightness according to day time. Have a task to check sunset and sunrise on the current region and progressively dim in or dim out after sunset and sunrise times.

I do not use google now, because my mic. s*cks... but this would be cool, to just "talk to the car", could you check the quality of your recordings ? I get background noise and a whine with mine. Calls seem to be ok, since noone complained...

Good idea to use a gesture to go "home". I want to install xposed today and set some apps to lower dpi. I will also set a gesture to go home... because that little icon is difficult to touch while driving.

I am also working on a screensaver (it will actually just dim out the screen (or show pictures, or whatever I come up with) after 30s of inactivity unless gps or selected apps are working..). Just did it today on my phone, I am gonna try on the car this evening.

I also wanted to set up a task to kill radio, bluetooth, etc apps when I turn 3rd party music players because, at the moment the sound just gets mixed as headunit apps have priority over 3rd party. I will post "task" if I manage.
[MTCB Android Head Units Q&A] 1-2-Hak:
That's a great idea on closing the system apps when third party ones are started.

You should really check out automatic. Will speed up your automation development ;)
[MTCB Android Head Units Q&A] pakidermo5000:
I am not as experienced as 1-2-Hak, but have followed the threads of OUNU, AN-21 and S150 for more than a year, and I can tell you that the HuiFei is much better than those, and has only minor issues that can all be "fixed". I would buy again without doubt.

Right now, the only thing that bothers me is the "long" (24s) boot up times.
[MTCB Android Head Units Q&A] zorantoma:
Contact names not showing on call? Posible fix.

For those of you that dont have all the contact names not shoving when you get a phone call,delite all the blank spaces between the numbers.

Exsample: 00386 123 123 will not show the name

00386123123 will show the name

When you corect the numbers,you have to resync the units phone book and start a fresh call with the changed number or it will not work.

[MTCB Android Head Units Q&A] tomc99:
Hi all.

I currently have 4.4.2 on my HU but would like to upgrade to a pre-rooted 4.4.4

Problem is, I use my HU in my 4x4 and have a heap of preloaded maps that will only work when loaded on the internal memory, so, I need a ROM that has not been reparted (I have about 4.3gb of maps).

I tried Coudu's ROM but can't use it due to the reparting.

Do any other pre-rooted, non-reparted 4.4.4 ROMs exist?

Thanks,

[MTCB Android Head Units Q&A] marco.lav:
There are several things to consider

1) your stereo could feed an amplified antenna (Example lanciaDelta)

** and with the current UH this does not happen.

2) The MCU does not control well the Tuner Chip.

* (With high probability)

3) electronics that they used in the UH is bad

** (When I do a half hour of time pieces pieces that UH!)

I would try to feed your old car radio and see if the central antenna is a wild voltage of 12 or 5 V.

in the case, you must provide the first thing to feed the antenna.

As for the proper use of the AF, I'm talking every day with the hope that Autopumpkin able to leverage their technical, it's almost certainly a problem of implementation.

We Italians, for the morphology of Italy, we hear more this issue.
[MTCB Android Head Units Q&A] delu77:
Thank you Marco, now is more clear!

I will test the original radio, ancd check the antenna voltage. I have also an unwired cable (antenna amp). If needed may I hook up to +12 (or +5) if the antenna output from Eonon is not enough ?

I am writing to support also, but first of all they don't understand why the radio needs to tune automatically the changed frequency.....ahhhh...chinese..... ;)
[MTCB Android Head Units Q&A] sixxkilur:
Looks to be the same as my GS-C0219 HU from Pumpkin yours has the European TV tuner that mine does not other than that nearly the same units.

Rooted mine with Root Master, then made a nandroid backup of the HU and flashed KLD_4.4.4_800x480_141223_rooted_light_reparted_init.d_v4.2 on it

runs fine for me.

[MTCB Android Head Units Q&A] sixxkilur:
MCU has to be for your head unit's hardware; MCU's are not interchangeable like the Android OS images are. you can change to different official MCU versions made for your unit only. Trying another type of MCU could brick your device.
[MTCB Android Head Units Q&A] marco.lav:

version changes is fine as long as the MCU you use was made for your head unit.

It IS ok to change the MCU version as long as it is an MCU from the same manufacturer of your unit - if you have a JY unit, then you can try ANY JY MCU and if you dont like it you can change it for ANY other JY MCU.

[MTCB Android Head Units Q&A] marco.lav:
yes, I have a power supply that feeds my amplified antenna, but I think the problem is in the gesione Tuner and not in the lack of signal
[MTCB Android Head Units Q&A] typos1:
If you want to hook it up to your aux in socket, you need to find the end of the cable from the aux input in your centre console and then connect it to the aux in on your head unit.

Theres a link to MCUs a few pages back.

If you dont want to cut the wire, then just unplug it or put up with it until you install a rear cam.

This is a generic Chinese stereo front, there are many many Chinese stereo manufacturers that use this front on Android stereos, WinCE stereos and non OS stereos, ALL of the 6 or 7 manufacturers that make the stereos in this thread also use this front, so you CANNOT tell which manufacturer makes a unit just by looking at it if it has this front, with the possible exception of Roadmaster who use slightly different button graphics.

The info you want is in the first page of the thread, have a look at it.

You need to side load some apps to install them or change your build.prop so it shows as a different device.

The Tomtom problem is common on KK devices, search the thread for info on how to get round it.

You could pm Coudu and ask him to do a 2Gb space for apps version, leaving 5Gb free for storage.

I m not sure what you mean exactly by "firmware" ? Have you read the first page of the thread ?

I m guessing not - ALL the versions (KGL, KLD, RM, GS, JY, MD, YZ) can use ANY of the Android update.images, but you can ONLY use and MCU.image if it is for the manufacturer of your unit (ie ONLY KGL MCUs on KGLs, ONLY KLD MCUs on KLDs, etc)

Both the wireless transmitter, receiver and camera all have power. The video rca composite plug is connected to the only video in on the unit. Yet no cam on head unit. It is supposed to switch to detected signal automatically I assume. If not what app, feature or settings to use backup cam.; and are there any other wires on the head unit that I need to hook up. I had the same cam kit wireless add-on connected to the old head unit that used to be installed on the car. Also the can bus wires are most of these useless on a 2006 GM vehicle?
[MTCB Android Head Units Q&A] delu77:
No I don't. The original does not need it. Anyway I will try to connect the old radio and check the output voltage...

EDIT: I have read in other forums to "hook up" the blue wire (antenna amp, number 6). But where?
[MTCB Android Head Units Q&A] typos1:
The original DOES need it, but it is integral with the original head unit, on most after market units it is NOT integral and thats where the power injector (often incorrectly describes as a "booster") comes in.

You hook up the blue wire to the blue wire on the power injector, but as you have not got one, you cant.

Get one, they are very cheap and it will improve your reception.
