No. It will work ... in a non-useless way. It's still not perfectly clear or noise-free, but people will be able to understand you during conversation, something that's not the case in the original state of the unit.

An if you're a bit handy, it's perfectly possible to do this stuff without leaving any traces of your work.

1) to open the machine without breaking the waranty seal which will be found most of the time on one of the 2 screws on the side of the unit (which, all things considered, is the WORST place to put a waranty sticker : just by installing the unit, you can already rupture the sticker as it rubbs against the mounting bracket's sides !!!).

To do that :

- remove screen (in my case, 4 screws on either side of the screen) so you can look "into the machine".

- remove ALL screws of the backplate/heatsink so it comes deattached

- remove the two bottom side screws.

- unhinge all the flatcables

- you can now gently pry the bottom part of the unit from the top part (where the DVD ect is situated). Done, unit is open, waranty sticker has not been broken. :)

Yeah, the thought has occured to me. Not sure if I will do it : I can be really penurious sometimes.

In honesty, all units I have tested in my car before the JY had good-enough AMPs. But the JY sounds .... slightly puny.

I had considered the i-sotec i-soamp 4CX-S for this which I already find too expensive.

I've no doub the PDX is a great piece of hardware, but with that pricetag it is well out of my reach.
[MTCB Android Head Units Q&A] Krisjan89:
The pdx is not that exspensive, found a internet shop in estonia, that sells them for around 500 euro. But on a sidenote a good 4 channel amp, will useualy cost 250-500 euros
[MTCB Android Head Units Q&A] kaween:
1) Well, Typos1 might bludgeon me to death if I have it wrong, but the Android-part of the update (update.img) is independant of the mfg'er. As long as you pick the correct CPU and resolution and your unit belongs to this RK3xxx family, you should be fine. For what it's worth, the screenshot of that Ford-Witson are a dead-ringer of the layouts and UI's I saw on the original software that my JY came with.

5) I've compared the RK3066 with the MST786, and already the RK3066 reacts faster and I'm quite sure it would serve you well. However, I bought my RK3188 for 30USD more than the same model with RK3066 was offered, and I don't regret it for a moment. Honestly ? I'd try to shop around and find a quad core with a 1024x600 screen. Coming from a cheap-*ss like me, that's quite a statement. Something like this h t t p://www.aliexpress.com/store/product/Silver-HD-1024-600-RK3188-Quad-Core-CPU16GB-Flash-Android-4-4-Car-DVD-For-Ford/616809_32327573845.html for example.

Poweramp Pro's EQ will of course be usable to boost HU sound quality (within Poweramp of course) and does a rather good job at it in my opinion.

But I switch it off and let Viper4Android do the work generally speaking.

---------- Post added at 12:00 PM ---------- Previous post was at 11:57 AM ----------

Yup. The Isotec can be had between 250 and 300€. I've toyed with them once and they were certainly good enough for me.

The PDX does indeed go for about 500€ when I look around here. Can't spend that kind of money on an amp in these times sadly.

[MTCB Android Head Units Q&A] MAXIGEPPO2:
I follow this forum for ages.

I installed the rom of Malays, beautiful. With Malays for the time that gives us

But I wanted to ask a question.

What is the best player for Android?
[MTCB Android Head Units Q&A] Siffion:
There are many music players for Android, the best however is down to personal preference on features etc etc.

I use Poweramp and Spotify premium account
[MTCB Android Head Units Q&A] typos1:
"Bluetooth Speaker" and "Headset" work as well on my Klyde, though the best sounding is "Headset" and this has been recommended by others as the setting to use. Have you played with ALL settings including in "expert" mode ? Just enabling Viper does not really make much difference you have to play around with the settings.

No changelog I m afraid.

You dont need to back up your firmware as there are copies on the fileserver if things go wrong. Rooting is a prerequisite for Viper. Sounds like youve got 4.2.2 on you unit. Its not that KYD are not "popular" its just not so many people have bought them as they are not as commonly available as some of the other makes, its essentially theyre the same unit, at least on the Android side.

Have you tried "force enable" in Viper ?

Lol, no bludgeoning from me, the Android side is, indeed independent. :)
[MTCB Android Head Units Q&A] DJCannonball:
now that my headunit is finally operational (after almost 3 months struggling), i can start connecting and tuning the rest of the audio-components.

it came to my attention that my headunit's build-in amplifier (KLD) has some nasty harsh frequency curve somewhere around mid-range.

The unit's stock EQ is pretty much worthless as it can't even 'equalize' the unwanted frequencies properly. my experience is that the EQ can only alter some frequencies for about 1 or 1,5 db, pretty much worthless. if the amplifier would output an equally clear frequencyrange from 20 hz to let's say 24 khz you would not need an EQ after all.

i have not tested it yet, but i think it outputs a clear signal "as is" thru the RCA connectors, switch off all possible signalprocessing on the headunit, and use an external quality amplifier to power the speakers.
[MTCB Android Head Units Q&A] Graves33:
Yes i have tried them all and want to use headset. But the only profile that activates is phone speaker for some odd reason. I will play around with it again today just to verify. Thank u
[MTCB Android Head Units Q&A] kaween:
And does in work in English ?

If so, chances are the French language config was stripped from the build.

You should ask Malasyk about that.
[MTCB Android Head Units Q&A] typos1:
It may help if you go to the Viper site and read the guide there, it explains all about the different settings.
[MTCB Android Head Units Q&A] kaween:
Yeah, that's my feeling too. Hence my remarks regarding the worth of the unit's hardware EQ and the "slightly puny soundscape".

D*mn you both (you and Krisjan89) for pushing me towards that I-soAmp part. :silly:
[MTCB Android Head Units Q&A] Krisjan89:
It could be much worse, i've aleready spent around 2500 euro's on my sound system and still have long way to go, before i am satisfied. ( still missing sound deadening the car and a sound processor) :cowboy:
[MTCB Android Head Units Q&A] DRidilla:
I donated to Malaysk so that the next time I say "Please add a settings toggle to remove the brightness slider from the notification shade." he takes me just a little bit more seriously. :P :P :P
[MTCB Android Head Units Q&A] matekhr:
The same here, but for another language. And a wrong message when powering the unit off.
[MTCB Android Head Units Q&A] edit:
How can I tell if what is on the fileserver is what I have on my unit... from the HU picture I shot with my phone it has android 4.4.4 and that blue interface that I like (you can see it in the link i posted)... till i get a better one :P
[MTCB Android Head Units Q&A] kaween:
I wouldn't be surprised if nigh all the launguage files except Russian and English will have this issue. Again : you'll have to ask Malasyk if this was his doing, or it was the state in which he received the source file.

I see quite a lot of image files coming from 4pda.ru where the "strip everything except Russian, English and sometimes German" is common practice.
[MTCB Android Head Units Q&A] matekhr:
I don't think it's a stripped rom, I beleive Malaysk missed somthing. He will fix it for sure.
[MTCB Android Head Units Q&A] kaween:
Sorry for the slightly off-topic nature :

Lol. That's actually the first thing I did on my car : 6 months old, I parked it on my front lawn on a beautiful summer weekend, I stripped the complete interior of the car to the metal (only the steering wheel and the dash remained), used both sound deadening as dampening materials (Alubutyl and a heavy cloth-like material on top of that) on the full interior inclusive doors, wheel arches, roof, firewall (a ***** when you don't dare to remove the complete dash .... but it's done).

My neighbours thought I had gone bonkers. My wife was sure I was. :)

But the result was well worth the trouble and I can only recommend it.

Costed me 3 days (long weekend :) ) and about 250€ worth of material. Afterwards the car received a complete anti-rust treatment (Dinitrol) in all hollow spaces, arches, panels and bottom of the car. That's 4 years ago, and so far "rust" is something other people have to worry about.

Last car I did this kind of work on was my dad's Ford Escort. After 20 years of misserable Belgian weather, the car was still rust-free. My dad eventually did away with it because the enigne couldn't cope with lead-free fuel and he got tired of the "mix the juice" thing at each petrol-stop. :D (and he got bored of it, hence he bought another, even more boring car : a Ford Fusion) :D

[MTCB Android Head Units Q&A] typos1:
I cant see any blue interface, I can see some blue wallpaper though. There are 3 launchers - the KGL one, the KLD one and the standard "MTC" one, the devs make special launchers for KGL and KLD, other makes (mainly JY and KYD) use the standard launcher, you will find the standard launcher (called Launcher2mtc2.apk) in both KGL and KLD images anyway (at least I have in several of the versions I ve flashed), even if the KGL or KLD launchers are installed. To be honest it isnt that important as all versions from all manufacturers work ("all versions" means all versions that match your processor and screen res). Backup is not important really, just try out some ROMs, you can change the launcher for the MTC one if the ROM you prefer has the KGL or KLD launcher anyway.

Yeah, thats a replication of the guide from the Viper site.

I installed the last malaysk 20 for 800x480 rk 3066 KLD and the KLD6 V54 MCU.

THe mcu works great after reconfiguring all the radio settings using my old screenshoot and it shutdown after 2 hours that is great for me...

But I got an issue with Malaysk... even after doing a factory reset....

At the boot it starts all the music player I installed... playing alltogether but when I shutted down I was listening only MTCMusic....

I installed Google Play Music, poweramp and JRT Music player.

I use always this player because it's faster to start on boot...

Also after factory reset and reinstalling everything I still got an error when I push HOME button... Application "start application" goes to an abnormal termination...

looks like it's xposedMtc... but no errors in xposed log.....

Dumb question

Hey Group, I installed update_4_4_4_800X480_RK3066_20_MAL_NEXT_LAUNCHER_24_05_2015 and so far everything is good (haven't done much testing). I did notice that Titanium Backup was part of the image but it keeps crashing. Just for verification the only way to possibly uninstall/remove and reinstall is just find and remove the apk either via adb or local term session?

I didn't do a factory reset yet so this may fix the issue also but I figured I'd check before starting from scratch.

For posterity this is installed on a G2110. So far 0 issues with upgrading MCU and ROM :D
[MTCB Android Head Units Q&A] MayfairDROID:
There is a setting in settings that starts music on read of SD card. Disable this, and it will stop :)
[MTCB Android Head Units Q&A] agentdr8:
Yes, but what action would trigger the script? Something has to tell everything else that the system is coming out of sleep. Or I suppose the sledgehammer approach would be to write a service that constantly checks the screen on state, and when it isn't on, set a pref to indicate screen off, and then check that upon waking.

Probably not a popular or feasible suggestion, but maybe that driver can learn English? :D

Are you using the default MTC launcher? If not, you should probably disable the Volume display override if it's enabled in XMTC. If you are, try grabbing a logcat for me.
[MTCB Android Head Units Q&A] bubba77:
Mayfair thank you for the reply. Would you happen to know where in the settings this may be located. Will take a look again tonight. I thought I had been through everything and don't remember ever seeing a setting like you mention..

Do you mean an English driver who doesnt speak, or a driver that doesnt speak English ? ! :)

Doesnt really mean anything to us here as Eonon are just re-sellers not manufacturers, its more informative to tell us whether yours is a KLD, JY etc.

I think hes gonna wait until we have a fix, its only been a day or so.
[MTCB Android Head Units Q&A] MayfairDROID:
I dont blame him. If he has someone with a Klyde near him, he could test it and make sure its not the card itself. I would think that if it was the card, even in a 800x480 unit, it would still have the same issue....
[MTCB Android Head Units Q&A] SpEnTBoY:
Which is why I said for posterity. It may mean nothing to you, but to a few others that had been asking about this model specifically it was clarification for them (and another search point within the thread) that it was possible to upgrade it if they were having any reservations.

The factory MCU was an older v2.04 (MTCB-JY-V2.04) and it's a JY that was running 4.2.2
[MTCB Android Head Units Q&A] typos1:
We know it is no the card because the fault affects several people, all with RK3188 cards and 1024x600 screens, there is a known problem with RK3188 cards and 1024x600 screens.

I was just trying to point out that as Eonon are not the manufacturers its useless adding the model number. I ve not come across any others asking the same question.

It doesnt really matter what version of the MCU or Android it had from the factory, the current MCU and Android versions are more important for trouble shooting.

Its a good idea to get used to totally ignoring the Eonon stickers and their made up model numbers and using the correct manufacturer and screen size/processor type for identification, it will be easier for you and for others to help you. :)

a week of reading and I am finally caught up...I feel like I just binge watched a series on Netflix and have to wait a year for the next season! lol...

Has anyone had success flashing the KLD_2.55 to a KLD2 MCU? I saw a couple folks tried but it wasn't clear to me if they were successful. I am not going to be the guinee pig, but would love the 2hour sleep feature if it will not mess up the MCU. Thanks again.
[MTCB Android Head Units Q&A] typos1:
I know what you mean, I did the same once, I also did it with the 4pda.ru forum for these units !

I m pretty sure KLD MCU v2.55 wont work properly if you have a numbered MCU, I think you need the KLD6 MCU.

I and others have installed the wrong MCU before and it will mess up your buttons (they will have different functions to their label), radio maybe set for the wrong radio IC, amp set for the wrong amp Ic, but its easily undone by re-flashing with a correct MCU. Previously people reported that flashing the wrong MCU "will brick your unit" from experience I would say that this is incorrect, but I understand if you dont want to try it.

Sensible the higher overall speed, significantly much higher response. If You use iGO navi with "Nuance TTS" sound engine, You can feel that the speed has been boosted up with lot of levels.

so it's really this combination at this moment that doesn't work very well: KLD + 1024x600 + RK3188 SoM

but still the build-in amplifier of the unit sounds like.... crap i can't find any better expression (sorry)

my subwoofer sounds great because it's powered by an external amp.

i'll be heading for the carstereo stores today to find me some decent 4 or 5-channel amp which can 'low-cut' all 4 speaker-outputs (except sub ofcourse)

I bought another head unit as my first one was crap out of the box and this one is working pretty good except for SWC and illumination which I will sort out later. What Im curious about now is does anyone know if its possible to get the car recorder app to record from the "video in" rca jacks instead of just the usb camera? I have a decent front view camera that hooks up via the video in connectors and it works really well except that car recorder doesnt recognize it is there or any other app ive downloaded and tried.
