[MTCB Android Head Units Q&A] TomKnowles:
Hi people.

First and foremost i want to say thank you to all the people who have posted on this thread, it's an amazing resource.

I bought and fitted myself a JY 1024x600 unit running 4.4.4 and installed it before the easter bank holiday. I did about 600 miles over the long weekend and have been tweaking and playing with the set up.

Overall I am very happy with it, a few minor issues to sort, but none that have made me regret buying the unit as of yet. Sound quality out of the box is pretty awful but with a little playing i have got it to a level that is satisfactory.

There's a horrific thud sent through the RCA's to my amps if i just turn the engine straight off, so I've ordered a couple of ground loop isolators in the hope of removing this.

Getting the time to display correctly was a bit of a pig, the only combination that would work is : GPS time update OFF, Automatic network time ON, Automatic Timezone OFF. Any other combination wouldn't work.

I am using Waze to navigate, and the auto night time mode doesn't work, whether this is related to the issue above, I don't know, but i suspect it is (GPS signal seems to give wrong time code). Would it be possible to set Tasker to turn it from Day to Night and Night to Day depending on sunrise and sunset times for my country?

My mic seems to completely not work, but that's an external that's plugged in, going to try removing that and seeing if it's just a faulty mic and whether or not the internal one works, even if it does it will probably be pretty bad going by other peoples experience.

I am yet to install one of the custom roms, root the device or update the MCU, as it is working well enough now, and without experience in these things do not wish to screw it up, but can see myself giving it a go in the not too distant future.

Once again, thanks to everyone on XDA, the support available on this thread convinced me to take the risk and buy one.

I am using Malysks latest 3 April ROM and am trying to run legit TomTom from playstore. It installs fine but crashes as soon as I start. Anyone have a fix for this (layman friendly please)

It has been mentioned here: http://xdaforums.com/showpost.php?p=54439133&postcount=2064

If you don't use external power either it is not seen at all or the speed is very slow. Thus the frame drops. I think that he only uses one usb port to power the HDD.

You should try an ssd if you have one laying around. They require less energy.
[MTCB Android Head Units Q&A] typos1:
What I m getting at is its not an actual problem as such, its kinda to be expected that an HDD is gonna need an extra power source and using one sorts the problem, unlike the USB stick problem which is bizarre, is not to be expected and has no solution, at least not yet . . .
[MTCB Android Head Units Q&A] ga!nusha:
I see what you mean. I think the best solution is to test an SSD in order to see if he still has the frame drops. Besides, SSD's are better suited for cars than HDD's as they don't require flat, not bumpy, surface.

LE: seeing that you are online, i'd like to take advange and ask you a question. If i'm not mistaken you have an KLD with DVB. Have you bought separately the DVB or it came with the unit ? Do you know if there's any available for KLD's ? I'm interested in something internal, not on USB :)
[MTCB Android Head Units Q&A] martinblanco20:
Finally i m upgrade to mcu kld 2.40 and coudu 4.4.4.

The unit works well, my only problem is when the stereo is running sometime the sound only came from front right speaker. I go to amplifier setting but cant setting nothing because the amplifier options are not responding.

I reset the unit and came to normality for a while.

Someone have an idea could it happen??

Thank!!!
[MTCB Android Head Units Q&A] corwest:
Unless something hooks to the SoC version in the build prop or something i Dont see why not? However I wont be the one to test since I just got my KLD yesterday...

ipod wiring / usb digital tv

Ok.. in my unit there are 2 usb only. But it´s possible open the unit and fit an exclusive ipod usb cable?

Did you have wiring diagram?

Best regards!
[MTCB Android Head Units Q&A] typos1:
Klyde use internal TV cards, but the other makes dont seem to, if you intend to use the TV when moving (for passengers or for the radio only, obviously) then you are best off with the dual tuner TV card.

I do have a spare single tuner card if youre interested, pm me.

---------- Post added at 06:34 PM ---------- Previous post was at 06:29 PM ----------

If thats the 8Gb version then it will be the same as the dual core version, Klyde assure me its the same, the only difference is the partitioning on the 16Gb version, the user who gave DSA the firmware has the 8Gb version . . . unless youve found something different about it DSA ? Was it the 16Gb version maybe ? But as I said echudoba has the 8Gb version, and I think hes put the firmware on his unit.

Only the SoM (its not an SoC) is different on the RK3188 versions (as I ve said a lot of times !!), EVERY other bit of hardware is the same, so MCU versions are THE SAME FOR ALL UNITS !!

Hello,

again a short update on installation of the "new" tomtom go app. The problem: TomTom tries to install the map on the internal NAND-memory, which is too small for a larger map such like Europe. I got it now also working with the install-recovery.sh skript written by dsa8310, please see above, thanks again a lot for the nice support.

I had to change the destination path in the install-recovery.sh and one has to take care that this destination path, where the script binds in the external sd card, doesn' exist already. Then it works nicely, much more conveniant then fouldermount.

Best regards,

Michael
[MTCB Android Head Units Q&A] echudoba:
Yes I did do the update and mcu, It's 2.44 and I have an 8Gb version. I am tempted to try the one of the ROM's on page 1. If I did and it would not load do you think it is possible to reload my original update.img? from recovery. I have gotten into recovery from the instructions on page 1.
[MTCB Android Head Units Q&A] pbiggane:
I've determine the two cables on the back of the quadlock are indeed fiber optic cables for the MOST bus and it is my understanding these interface with the communications equipment, including the steering wheel controls. I think I need to close the open loop with a MOST terminator, however I may need to purchase the connects2 infodapter for everything to work. Pretty frustrated with this, since the seller said the unit was plug and play for my car and that steering wheel controls would work. This is the can bus decoder that came with the car, I also uploaded some photos of the quadlock with fiber optics and a wiring schematic that may be helpful for others users.
[MTCB Android Head Units Q&A] corwest:
So who would know why there is a constant static noise coming from the speakers with my KLD unit? It is there regardless of what I'm doing on the unit and the volume if the static doesn't change at all.
[MTCB Android Head Units Q&A] Malaysk:
Where can I download the factory firmware without root? Thank U.
[MTCB Android Head Units Q&A] echudoba:
I will wait for you guys to put something together. I'm still evaluating my occasional hang up on boot and wi-fi inconsistency. It works great, very responsive, the only change I am looking for is higher pixie density which requires a rooted device.

I'm new to some of the language on the forum, exactly what does pre-rooted version mean. I take it you made some changes to the original files I sent you.
[MTCB Android Head Units Q&A] DJCannonball:
Hey i got some news!

my seller sent me kld_rk3066_h(150104).rar

i put the unit back into the dashboard, fired it up, flashed the firmware i got.

tadaah.. no more crashes!

a little side-note: there was also a MCU.IMG but it didn't take it for flashing.

i deleted the update.img so MCU.IMG was the onlything left on the sd, tried flasing again, but it returned the image 'invalid'

never the less, it kept running for almost 2 hours without crashing.. amazing.

i can't explain why all those other firmwares were causing crashes, and this single firmware doesn't

there were 3 things that came to my attention:

1) the unit seems to have difficulties mounting and unmounting several storagedevices.

when an mp3 is playing and i turn the unit off (acc-off) it shuts down, and when i turn it back on it keeps complaining that i didn't unmount it properly. sometimes it does and sometimes it doesn't i can't tell why.

2) the second thing is, the trouble i had in the beginning is back: when music is playing i start Sygic at that moment the music stops (like the unit cannot find any mp3s in the sd). gps sound is set to mixing. mixinglevel is set to '0'

even when i'm playing music thru A2DP blutooth from my phone. the music stops suddenly when starting Sygic.

Sygic was set to GPS-application.

3) sometimes the volumebutton stopped working. when playing music (or any other sound) it keeps playing but i cannot change the volume. the strange thing is: volume up and down on my steeringwheel DO work, while the onboard volume knob does nothing :eek:

A reboot at that point doesn't help, only a hard reboot gets the volumeknob working again.

i'm beginning to suspect all these 3 things have something to do with the MCU being faulty. my stock mcu was KLD 2.30 i flashed it to v2.40 but the mcu.img i got from my seller didn't flash (invalid img) i don't know what version it is.

i least i got rid of those horrible crashes :angel:

I have an Erisin ES9401A with MTCB-KGL4-v2.01 firmware. Pleae help me, if I want upgrade firmware what you recommend upgrading?

What is the latest official fit this model?

And maybe a dumb question. What happen if I upgrade to a 1024x600 firmware if my unit has 800x480 screen?

Thanks
[MTCB Android Head Units Q&A] DJCannonball:
sure no problem, where do i send it to?

btw i think it's 4th of Januari in stead the 1st of april. (the other way around) and yes for 1024x600 model
[MTCB Android Head Units Q&A] peti007:
I checked today and in PA the resume on start wasn't enabled. Sorry, my fault! But the issue still there if I used Mode switch override before shutdown.

So the situation: In Mode switch override just the Radio is selected (and PA is the default music app). If I listen to music with PA and then press the Mode button, PA paused and Radio app goes foreground and sounds.Then I press Mode button again, Radio muted and PA goes foreground, resumes playing music from last position. Now if I shutdown the car, on next boot PA starts, but Radio too! And Radio sounds, PA paused.

If I close Radio with the physical BACK button before shutdown the car, on next boot PA starts playing music from last state.

I think XposedMTC doesn't close Radio app correctly on Mode switch override as the BACK button does.

I cant be the only one with this issue with the RK3066 HeadUnit app. The switches keep turning off.

[MTCB Android Head Units Q&A] peti007:
Yes
[MTCB Android Head Units Q&A] agentdr8:
I'm just switching the audio output via the AudioManager instance, so that would probably be why. I can rewrite it to close the Radio app instead. Then it should never launch on boot unless it's specifically in the foreground.

Sounds great, thanks again!

Canbus mazda 3 2010

So I have a KLD model purchased from Autopumpkin for a 2010 Mazda 3 iTouring (without Bose)

MCU 2.40

(rooted 4.4 from the google drive link from the first page.

tomtom works

the dpi is set to 180 on this image

the radio app looks correct and not warped

everything from the play store has worked for me

google voice search still crashes)

The canbus that came with the unit did not work and on a whim found a site that did sell them.

ROADNAVI

CAN-bus Decoder for RN S90 S100 S150 S160

RN Model: C034 Mazda 3

(they have several models for mazda 3, had to email the seller to know which one would work)

After a month of waiting for it to cross the sea. I plugged it in, just replacing the canbus decoder(it came with a wiring harness)

The Steering wheel control volume control clicker now works,

Mode button now switches between the many inputs.

Radio station silences when switching between inputs.

Radiostations are displayed on the minidisplay.

The forward and back buttons do work and beep, but might need to tinker with it to make it forward songs.

Before this the minidispay only showed "NAVI SYSTEM"

Android Auto(ish)

Gday guys,

This app attempts to replicate android auto on your phone, for those who dont wont to update their car stereos, It does work (limited) on our HuiFei units and it looks very good for a beta.

Mapping, very good so far, follow doesnt work however the arrowhead for the compass works

Phone functions no good (lists mobile network not available) duh, no phone in our units

Music, Google music woking, I would like to change this to poweramp though.

If we could get the phone function to forward this onto your connected phone it could be a real competitor for the home screen.

[MTCB Android Head Units Q&A] Brendo:
Yep, I got issues with enable toast, enable media keys settings being lost as soon as I press back button. Rest seem ok. Only happening on 2.14. If I leave the settings window open, they stay set until exited
[MTCB Android Head Units Q&A] pants001:
I have same issue, if i stay within the settings page they turn off after a few seconds. I have to set to On then jump out quickly.

This then stays working so i presume they are still On

RK3066 HeadUnit app

Hi guys!

Problems with switches - this is a bug of android caused that there are too many SwitchPreferences on one Activity. i have changed prefs to the CheckBoxes, which should be more usable.

+ some fixes

1. Start music app via "Play" command

2. Music app does not started if system apps already started (Stock music, radio, etc)

Check out new beta version: http://petro.ws/s/mtc-service/MTC-Service-2.15b2.apk

---------- Post added at 09:35 AM ---------- Previous post was at 09:33 AM ----------

Please, test new 2.15b2 version, if it is ok - i will update it on Google Play.

Ohh wow. for first time Petrows your app auto starts JetAudio playing on boot.

Edit: Maybe it was in early versions just i was in such a hurry to get out of settings before they turned off again

(Thanks for your efforts on this app. It makes the difference between good car stereo and excellent)

Edit2: I cant have babies but you know what i mean
[MTCB Android Head Units Q&A] typos1:
I think it would be easy enough to un brick it, but better not try it if DSA thinks there are differences, I ve not heard back from Klyde yet.

I know some BMWs have MOST, but they also have CAN Bus as well, I thought MOST was only for audio/video, so there should be some CAN Bus lines there somewhere. There are quite a few people with BMWs who have not reported the problems you have.

There are ? What are the differences DSA ?

Glad to hear its sorted !!

---------- Post added at 11:05 AM ---------- Previous post was at 10:53 AM ----------

Hmm, dont know, people dont usually get this, take it youve checked the earth, didnt you mention about a ground loop isolator ? Has it come yet ? What car have you got ?

Normally root is obtained by installing an appp or flashing a zip, but since 4.4.2 files have had to be added to the firmware image and then flashed, basically a modified firmware update that will give you a rooted device once installed. There are a couple of custom firmwares avaible as well, but seing as DSA says that there are actually differences in the RK3066 and RK3188 firmware after all best not try any dual core firmware, Malaysk makes one of the custom firmwares and he has asked for a copy of the RK3188 firmware, so I m guessing they ll be RK3188 custom firmware that you can try soon :)

Glad youre up and running again !

Thats the only difference ?

You dont have an EONON - EONON are just sellers, to find out what unit you have, go to the "about" screen, as for firmware, as it says on the first page, you can try any Android version, but ONLY MCU versions that match your device.

It IS a silly question !! 1024x600 firmware will work fine, but teh right side and bottom of the screen will not be visible. Install rooted firmware and change the DPI yourself, or use Malaysk's firmware which has an app for it built in.

---------- Post added at 11:07 AM ---------- Previous post was at 11:05 AM ----------

Lol, I m not impressed with it either from what I ve seen !

---------- Post added at 11:10 AM ---------- Previous post was at 11:07 AM ----------

Great news !

You werent really expecting it to be cylindrical were you ? It wasnt cylindrical in the picture !

I read the listing and it does sound like a good booster though, if you get good results, I may even get one and stop using my OEM booster/cylinder set up :)
[MTCB Android Head Units Q&A] ga!nusha:
Eonon products are KLD. Perhaps we should create a directory with all the resellers and the original manufacturers ?
[MTCB Android Head Units Q&A] typos1:
Are you sure ? - I thought they sold a couple of manufacturer's devices.
[MTCB Android Head Units Q&A] ga!nusha:
From my local forum i can confirm that both Mazda 3 models from eonon are made by KLD (i have one). Another friend has the eonon for corolla and it it also a KLD. i assume all android versions from eonon are KLD

I haven't looked at all of their models, but from the pictures it seems that all of them have the 4.2 KLD radio app :)
[MTCB Android Head Units Q&A] typos1:
Havent checked their site for a while but I m sure I ve seen other makes as well. People really need to check their version and forget about the seller, I d suggest to pakidermo that he add a note to that affect to the first page, but no one would bother to read it !
[MTCB Android Head Units Q&A] DJCannonball:
here's the firmware i got from my seller.

it's ment for KLD_4.4.4_rk3066_1024x600(150104)

it seems that this is the ONLY firmware that doesn't crash my unit after 15 minutes of cpu-load

somebody put this on the repositories:

https://www.wetransfer.com/download...ea2e0952eb84cb9abb72680d20150408113357/18ace6

a little sidenote: the enclosed mcu.img doesn't seem to flash
[MTCB Android Head Units Q&A] ga!nusha:
Depends on the car you have, but in most cases is because your car uses an amplifier. Depending on what car you have the solution can be as simple as adding some noise filters (not noise cancelers !) and as complicated as rewirering (my case with a 08 mazdaspeed 3 bose)

In other news, here is the latest official Eonon firmware for KLD 800x480 from 03.03.15: https://www.wetransfer.com/download...1b24b08640c8081b239e98c920150408115121/8b48d4
[MTCB Android Head Units Q&A] typos1:
I ve got Bose and I have no such problems, but I know some Audis need ground loop isolators to eliminate noise, it depends on how the Bose system is implemented and which system it is.

Rewiring does seem a bit drastic ! Was there no other solution ?

"Official Eonon" ? You mean its Eonon specific, or just a link theyve given you to KLD firmware ?

A good place to check is the forum for your car [MENTION=1677474]corwest[/MENTION] they often have tips on fitting aftermarket systems and the methods for these units the same as any other aftermarket system.
[MTCB Android Head Units Q&A] ga!nusha:
In my case i needed to take the pre-outs of the unit and solder them to the harness adaptor. On max i could bearly hear the music with the engine running. Other units from eonon (the win-ce ones) don't need this manipulation. Don't know why...

Here's a video(not mine) of what i did: https://www.youtube.com/watch?v=ZnSsZtXvNMw

Then i added ground loop isolators to remove static.

The firmware is the one KLD sent to eonon. It is not eonon specific. Sorry for confusion.
[MTCB Android Head Units Q&A] Malaysk:

[MTCB Android Head Units Q&A] ga!nusha:
Ok. So it's not new. I shared it as i received it. Didn't have time to decompile it. Btw Malaysk, i've seen that you know your way round rom building. I have trouble finding the kernel boot logo. I am creating a custom firmware for my unit and i was thinking of changing that too but i cannot find it in kernel.img or boot.img. Do you know where it is ?
[MTCB Android Head Units Q&A] pbiggane:
typos1, I'm not sure why I can't respond to your latest post, the only option is for me to respond to my first post. Anyway, I searched the BMW posts the other day on this forum and I think I'm just the lucky one who has a weird setup. I pulled the head unit apart, I'm going to enclose the mainboard in a plastic case and attach +12V, tap into the can bus from the oem unit to the can bus decoder that came with the unit and attach the fiber optic cables to the oem main board, this should keep the MOST bus in the loop and let the car think that the factory unit is still plugged in, hopefully this will restore my steering wheel controls and kill the SOS error I receive on my dash cluster when I start the car. For anyone that wants to know what the inside of the BMW professional head unit looks like, I've attached a couple photos. One of the photos is of the main board itself, showing the fiber optic cables and the other photo is of the daughter board that plugs into the main board which houses the quadlock connector and the analog stereo output. This solution should also rid the need of purchasing the expensive chime retention kit that some aftermarket companies sell and I won't need to purchase any additional harnesses that may or may not work.
