Do you perhaps have MTCControlInfo.apk ?

Thanks
[MTCB Android Head Units Q&A] coudu:
You're right, I removed MTCControlSettings.apk as it doesn't do anything on my car (VW) and I thought it was the same on other cars...:( MTCControlInfo.apk is still included (displays canbus infos like rpm, battery charge, etc).

I'll leave MTCControlSettings.apk in future releases as it is usefull for some of you and just freeze it on my device.

Thanks guys for reporting. Just use the apk posted a few pages back if you need it until I upload a new FW.

I tried to use the buikd one, but it just not working as it should. It takes ages to read my entire SSD and it doesn't keep any database. I use Poweramp, for so many reasons :)

It has gestures, songs database (it takes 2-3 min first time, to build the playlists), search functionality, custom playlists, grouped playlists per artist, genre, etc, displays of Album Art and so many other features I can't remember now :)

For Video play, I use MX Player, which is another great app I recommend.

Eonon g2111. (JR deck)

I purchased the g2111 deck from eonon.

http://www.eonon.com/Car-DVD-Players/Android-Car-DVD/G2111.html

The thing never worked right. Out of the box the physical buttons worked but when trying to install any apps from the app store it gave error 491. So i did a factory reset. Now none of the physical buttons work and i still get the same error at the play store. The password listed for factory settings menu does not work: 126. The g2110 is mentioned on this forum but i cant find the g2111.

So i thought i would try and flash a new mcu and rom. I can't get the deck to install anything. I put the mcu and image on the root of the sd card and load into the gps slot and restart. Nothing, just loads like normal. I also tried the sd card slot as well, no go.

I included a pic of the about car page. There are pics of the front and back on the website: http://www.eonon.com/Car-DVD-Players/Android-Car-DVD/G2111.html.

Please help. The thing is absolutely useless as is.

An update on the problem I was having with installing a new update img. It seems like the Malaysk files I was downloading weren't complete or somehow corrupted. Clicking on the link on the first page opened a page with a rar. file with an option to view it. Clicked on that and a page opened the the udate img. When trying to download it an error message comes up. Might be the server. The same thing happened with the 4 files I tried. Does anyone have a link to a good file? I really want to try one his roms.

I tried poweramp too, but dont like the look or the layout. It is annoying that the built in music doesnt keep a database, but since I ve chagned from using an external HD to a USB drive it finds the files much quicker.

I thought once Viper was installed it was installed and starts at boot anyway ?
[MTCB Android Head Units Q&A] CARRisma:
I've recently installed the trial of Poweramp and I'm not overly fond of it either. The annoyance I have is that the screen is mostly blank when the music file hasn't got an album art. I would have thought there would have been an option for a spectrum analyser or even a basic visualiser. Even the basic built-in music app has a spectrum analyser. Sadly it seems that most other music apps are the same - album art or nothing.
[MTCB Android Head Units Q&A] devilsoft:
Yes, Viper is starting on BOOT_COMPLETED, but with that install-recovery, it's started sooner.
[MTCB Android Head Units Q&A] typos1:
Ah, right, thanks.
[MTCB Android Head Units Q&A] devilsoft:
Album art is automatically downloaded from internet, and it's a great feature in my opinion.

But even with the blank screen, I find Poweramp way more easier to be used with gestures and how the lists/albums.

The Spectrum is useless too, if you are using Viper FX, like I use :) Spectrum needs to be disabled to let Viper FX do the job.

Heatsink temp

Hi All,

I finally took the time to have the defective power amplifier of my unit KGL-7620 replaced. As I already thought, there are also some defective condensators :( . My question now is how hot the heatsink gets on your units after a hour of playing. I never took any notice of it in the past (when my unit was ok), but now my unit still is in my lab and when I took the unit from the desk to place it somewhere else I noticed the heatsink was seriously warm.

Thanks for your answers.

Microntek and True contacts

Hi guys!

Can anyone confirm that it works to place phonecalls from True contacts (Microntek head unit service installed) with a newer android version than:"KLD_4.4.4_1024x600_141223_rooted_light_reparted_init.d_v4.2.1".

I have tried some of the newer Malaysk roms and also newer Coudo roms, but True conacts just displays "calling" for a second but never really does something. So i reverted to "KLD_4.4.4_1024x600_141223_rooted_light_reparted_init.d_v4.2.1" and it works again. Any suggestions?

APN settings

hi all,

ive had one of these units for a while now and have valued all the work\updates that this thread has had to offer. im hoping someone can help with a small issue i have

ive always used a mifi dongle with my unit, powered by one of the usb ports without issue, on getting into the car i would

turn key to start car\unit

MiFi device would show as charging as soon as headunit powered up

switch mifi device on, and headunit would connect after 20 seconds or so.

im looking at a different option now by using a 4G usb dongle that will be phyicially connected to the unit, ive plugged this in and i see the device flashing, howver im unable to see where to enter the APN settings, (running coudo's 1/2/2015 rom). my question i suppose is

does the usb dongle have to be plugged into a specific usb port, or will any of the 2 do?

is the abillity to add the APN settings missing from the rom, if so is there an alternative rom i can use.

is there a 3rd party app i need to install to allow APN connections

thanks in advance

This is true. It's been mentioned several times in this Thread that 4G dongles are not compatible with current units. Hopefully future models. And not all 3G dongles are compatible either.

Mobile Networks, Mobile Network Settings, Change APN, and many other similar apps are just a shortcut to hidden data connection settings. An app like this is needed if provider settings are different from the default.

The dongle, if compatible, should work with either USB port.

I have JY HU and only have internal mic. I see you added external mic to the HU. Which quality difference of the sound is between external mic and the previous internal mic?

Which type external mic do you use? I found 3 type mic.

aliexpress.com/item/3-5mm...031402381.html

Is there any sound quality difference between these mic?

Where is the best place of the external mic?

The quality is ok between the two. My main problem was that the internal mic for the bluetooth calls was totally unusable but worked flawless with android apps and google. After the mod internal still works flawless and external mic is strictly for bluetooth calls. It still isnt perfect as I still get a little reverb but it is now usable at least. I used a mic that I had laying around and placed it up near my visor in my jetta. As for the mics you listed I cannot tell you the quality differences as I have no knowledge of them. As for your placement of external mic I can only tell you to try various locations to see what works best for you and in your vehicle.

I never had a problem with my phone (KGL and KLD units). I wouldn't expect that these units are compatible with every phone on the market. Even head units originally installed in many cars often include a note: not compatible with all phones. I would expect that the newest phones are more likely to be incompatible, rather than older ones (2 - 4 years old).

Hi, I don't know but the strange thing is that connecting this to my windows 7 pc it connect using the WEB apn that is the one for data sim card, I'm using a BIS SIM vodafone, same number, same traffic of the master SIM I've got in my smartphone...

and using WEB apn I pay for hotspot.

Connecting the USB dongle to the android unit car stereo it connect using the MOBILE APN, no additional costs... is the apn used by smartphone and tablet 3G.

I installed Mobile network setting and had a look, the apn were configured exactly, I tried to change the WEB apn to use the same address of the MOBILE apn address as I've done in my smartphone and it works... no costs in hotspotting..

But the surprise was that the connection doesn't work anymore.... so I uninstalled Mobile network setting and everything started working....

I will do this mod, if I have the external mic. I read from the connection. I know I have to remove C102 resistor and have to connect inner wire to the MIC+ pin of the bluetooth modul and I don't know where do I have to connect the shield wire? Maybe to the SGND pins of the BT modul?

I would like to share my experience of the coudus and malaysk rooms so far.

Have used both roms and I'm quite happy with both of them. One plus for malaysk is that the stock music player actually resumes last song, coudus doesn't. I have the sense that coudus boots a little faster than malaysk. Daily roads works super with both roms instead of the stock app that unmount the USB cam all the time. Sound has improved with the latest kgl update. Using viperfx for the first time.....

My phone has problems connecting via bt. Sometimes it connects sometimes it just opens on the speakers like I'm on a call. I have a Samsung s4. Obd works great on both roms over bluetooth. I think that's all. Oh and I'm 1.86 mcu cause all the others till now don't follow my car's illumination but stay on all the time.

Are you sure you have a correct MCU update file? Your HU seems to be the same as mine, try to boot into recovery for flashing the unit, you can do this by turning on the unit with the power button pressed for some seconds (unit must be completely off, turn off ignition for a couple of minutes before turning on) you can release button when leds start flashing, recovery should load and from there you will be able to see why if it rejects the update. Reset button should work in case you don´t want to wait it turnes of completely.

[MTCB Android Head Units Q&A] TooBusy:
Newer cars have a BT module or BT integrated, and probably an external microphone placed somewhere. This could be the best location. My car (VW) didn't have a BT module and therefore no mic either, but this was an option, so the car had a place for it, next to the roof lights. There are very good YouTube videos demonstrating how to install a mic in this place. I even bought an "original" VW mic, but that was waste of money; it's not compatible with these HUs.

Placing a mic on the sun visor might be even better except that the mic becomes visible. In this case, other people in the car won't be heard as well, which can be a good thing, depending on the preference. Other locations are A-pillar, dash board (just behind the steering wheel), etc. It's easy to find the most suitable placement by experiment.

When deciding which microphone to buy, it's important look at the specs. The links to the 3 mics in the above post reveal that the 2nd and 3rd mics are electrically the same, so the difference is the look and attachment type; sometimes also cable length. The 1st mic's specs are everyone's guess. Unfortunately, sellers on eBay, Aliexpress, etc cannot be always trusted for the specs they provide. They copy a lot of information from other sources, and it's not unusual to find that this information is wrong. Even worse, if you ask them a specific question, they might still give you a wrong answer.

Another problem is we don't know what the expected specs for a microphone are, in particular the impendence and maybe also sensitivity. Someone with good knowledge in electronics may eventually find out this for us. Additionally, a microphone compatible with KLD units may not suit JY units, for example, as reported before. Also, separating the internal and external mics introduces another variable into the equation.

For now, the only way to guess which mic will work well is feedback from other people. I'm using the same mic as in link 3 on a KLD unit; mics are not separated. The volume level is low, so I'm looking for a more sensitive one.
