I've searched for over an hour through this thread, and can't find where anyone lists which USB-OBD cable they are using. Few people have said they were ordering a particular cable, but never reported back on if it worked or not.

My bluetooth adapter works great with my android phone, and APPEARS to connect to my JY headunit, but it never prompts for the passcode! So it doesn't work properly with Torque...

If I can get Torque up and running on this headunit, I'll be a happy man. LOL
[MTCB Android Head Units Q&A] hadjistyllis:
It will never ask you for passcode. Just be sure its connected and configure torque to use bt devices

Bmw e46 android car audio

Hello

I install my car audio mcu.img (KGL v2.22) ,update.img (KLD_rk3066_android4.4 upgrade_800x480普清(150123) )

but my Video player dark ,sound level low(maximum volume low) , radio quality low.

why? :)
[MTCB Android Head Units Q&A] pk313:
i can confirm TA tunes...wherever it wants.

I have a KLD for a year now and I've tried everything ...

the internal tuner is standard should not have any problem with a good antenna

of course is that the management of frequencies RDS+TA does not work properly

but have not been able to figure out where is the logic that it does work ..

I decopiled the mtcradio (and change wrong pty) look inside but i'm uneable to reconize were is the logic of TA

The problem that we see is that..

The name of the stations so... RDS data, when the signal begins to be disturbed,.... disappear

it's obvious that the Radio it can not go looking for another frequency with the same data ... them already forgotten !

the station name must remain until the signal is lost . Is needed from the system to find another frequency with equal RDS

This is the problem but to discover were is write this in the apk.... is not so easy

We wait for some of us experienced modd that want to try . ..to decompile apk and check how is write

maybe a solution can be to take an app that works well on another device and put in comparison with the mtcradio that is installed here..

i know that this is a problem that affect mainly the Italy where frequencies change in certain areas each 3/4 Km so not so interesting for must of us here...but...please if somebody expert want to try something for us...

So I appeal to everyone here ... give us a hand to solve this thing pleaseeeee

i hope my english will be clear....

Hi Malaysk. Do you know whether to be possible to change the language of the file MTCCanBus.apk? I'm Italian and I have Opel Astra J. The radio android has changed the language of the info display of my car and now it is in English

[MTCB Android Head Units Q&A] Malaysk:
You do not understand ... you have to make a transfer of files from English into Italian. I then gather these files and send you

perform language translation
[MTCB Android Head Units Q&A] ga!nusha:
Thank you for your involvement Malaysk! Do you plan to replace the english one or you want to try to add it to the existing 10 ?

The actual languages supported for the CANBUS are: Cantonese, Taiwanese, Russian, Portuguese, Italian, French, Spanish, German, Arabic and of course, English.

I have also looked into that apk because i was trying to list on my display Waze and Spotify instead of other on my mazda 3 display but i have not found the string :)

[MENTION=6516720]giornistrani[/MENTION]: you first need to translate the content of the files in italian and then Malaysk will compile a new apk just for you !

[MTCB Android Head Units Q&A] Krisjan89:
i think the most easy thing would be to simply replace the english strings and arrays files. because when i looked around in arrays.xml i could see there where 2 set of language lists where the later one only supported english and chinese, that leads me to suspect that the program chooses wich language menu to use, based upon wich canbus options you choose
[MTCB Android Head Units Q&A] ga!nusha:
I agree. Adding a new language requieres way too many modifications and frankly not worth it.

However, i would love to be able to customise the "Other" text that shows when you open any app except the MCU ones. Unfortunately i can't find it :(

Go into factory settings and make sure TV is selevted.

I think it was OBD-Link, not sure, Torque works with 4.2.2 or 4.4.4, but not 4.4.2, what version have you got ?

The only difference between the dual core and the quad core is the processor, everything else is the same, even the software (although it is not interchangeable with the dual core because the partitioning and other bits you cant see are different), everything that works on the dual core also works on the quadcore, the MCUs are the same, the hardware is the same, having another thread is pointless and will just create more work for people who are searching for information - they will now have TWO threads to read, they also might not realise that there are dual core versions that have been around for a long time and therefore not search this thread and miss out on all the info in this thread !! There is firmware for both version on the fileserver including rooted quadcore versions, there is NOTHING special for the quad core units to add the the thread.

The ONLY built in app Viper will work with is the music app, it wont work with others, you have to use headset or bluetooth settings, you also have to enable Viper, visit the Viper site for a usage guide.

---------- Post added at 01:54 PM ---------- Previous post was at 01:50 PM ----------

Ah, now it seems we are getting somewhere ! You say the later version supports only English and Chinese, could [MENTION=6516720]giornistrani[/MENTION] just use an older MCU to get Italian ?

Whats inside the Tin Box??

I was wondering... whats actually inside a 2 DIN enclosure?

Is it filled with (clever) electronic boards - cables - an so on? - or is its (just) a motherboard of a kind, and 95% air?

The reason I ask?

Well - I have found an Android that would fit in my (to be) Alfa 159 - and even if its a 6-7" inch display, looks like a 2 DIN from the front - all photos shows that its a "1 HU housing"! Can that cause problems - like e.g. heat?

Cheers
[MTCB Android Head Units Q&A] typos1:
There are plenty of pictures of the inside in this thread use thread search or google to find them. A single DIN unit is fine.
[MTCB Android Head Units Q&A] patagonia1:
It will not prompt for a code but you have to enter it manualy in the bluetooth configuration of the HU before pairing. At least that this the trick for me.

Are you using xposedmtc? it is needed in order to make all OBDII bluetooth dongles to work, if not only very few will work (the one your hu seller sells)

I think you misunderstod my reply a little bit... What i meant was that arrays.XML file i the discussed apk mentioned 2 seperate language lists.

So my theory is that the APK chooses wich list to use, depending om wich canbus settings you have made in the factory settings menu

I have an Enonon G2110 with android 4.2. It has RK3066 1.6Ghz cortex A9 Dual core, DDR3 1GB. I am overall happy with the unit but I do have a couple questions for you all with this stereo.

1, The SWC controls randomly stop working and will stay not working until I reboot the unit. It is hooked up using the SWC1 wire through the SWC board on my steering wheel and hooked back to ground. It is the resistance type where every button has a different resistance. It programs correctly in the SWC program on the unit. I also have the canbus set to none in the "factory settings" area.

Any fix for this?

2, Bluetooth. When connected to my phone (LG G3) and making or receiving a phone call, the volume is super low through the unit. I have the unit hooked up using RCAs only through an amp in my car. The bluetooth connection for music works fine and is the correct volume. Is there anyway to turn up this volume on the unit? Or another program for bluetooth connection?

Also I can't get my PLX devices bluetooth KIWI to connect to this unit. I have the program TORQUE to obd2 monitoring. Not sure if its just an issue with the bluetooth program or something I am missing. The KIWI connects and works fine on my G3.

3, Screen flicker. My car has auto headlights. I have the headlight input wire hooked to the unit to change the brightness depending on day/night. When it switches modes from day to night the screen flickers for about 3 seconds. Is this normal? Any fix for this?

4, Google services stopped error. If i happen to kill the car and have to restart the engine, the unit says shutting down and the screen turns off for a moment and then back on. When it comes back on the error "google services has stopped" and I hit OK. Is there away around this? (besides not killing the car of course) It's not a big issue or anything but its something I have noticed.

Any help with this would be greatly appreciated!

But the AF problems on MTCRadio affect only Italy,

Keymap option? rear-view Camera guide lines in JY

3 questions for Joyous JY units

1) I searched but could not find what are the different Options in the the Keymap and Touchmap in the manufacture setting stand for?

I really did search and could not find it.. Option 1 , option 2 etc what are those referring to?

I really want to ReMap the DVD button to Ipod and another button to Music.

2) My rearview camera does not show the guide lines when I am in reverse. the camera works fine but how can I get those lines on the screen?

3) Does the Quad core speed up the boot up time noticeably? it is a bit annoying to wait 30 second before the radio turns on.

Bumping this question.

Can someone advise what focus settings they're using with Logitech C930 + DailyRoads? The problem seems to be that the app is not focusing the picture as often as it should. IE when I enter a really dark or bright area, the picture will become too dark or bright, and will not focus unless I interrupt and restart the recording. After focusing the picture looks great. The native Car Recorder app doesn't seem to have this problem.

Right now my focus is set to auto-focus, but I don't know what the continuous and infinite settings actually mean.

Your original (3/18/2015) pre-rooted is working very well for me.

Typos recommends I wait for even a newer version as it is a work in progress. Sounds like your discoveries may be related to an rk3188 in a rk3066 mcu.

[MTCB Android Head Units Q&A] chris.epp:
I finally heard from them, but it took some time to get them agree to fix/replace it, they kept wanting to know more, and with one email per day it's dragging on. Problem now is they want me to pay shipping and use Canada post specifically. $115 to send it back to them, and they said I pay for it. They sent me a dead unit, I should not be liable to pay for the costs in getting me a functioning unit. I've not sent it back and emailed for some further options, and clarification that they will reimburse me the shipping, so I'm not feeling very hopeful.

I may have to take it to paypal, but I don't know what they will do about it either. I've never had to do this before.

We'll see what happens, but based on this I would not recommend anyone buy from autopumpkin. I'll let you know if that changes. Meanwhile, if I have to go for refund and get one from somewhere else, any recommendations? anyone stocking units in NA?

Have you connected the orange wire ? do you have CAN Bus ?

What I meant was any bugs should be sorted in a month, so update to a newer version each time one comes out and expect the bugs to be gone in a month.

The MCU is entirely separate from the processor - we dont know where it is, it may be on the same board, maybe not, but it is the same for dual and quadcore versions - there is no "RK3066 MCU" !!

Maybe in the future, as DSA said, Klyde did not forsee demand for a 2Gb version (stupid), the RK3188 specs say it can take up to 4Gb of RAM and although I ve never seen anything with 4Gb, there are many RK3188 products with 2Gb RAM.

She is a sales lady and doesnt know much, she is wrong.

Paypal will sort it out because you paid for a product and it did not work.

That is the JY launcher.

to amp or not to amp

Hi, for the ones using external amps on your HU´s, have you experienced a real increase in sound quality and not just "more volume"? I have an amp thay I haven´t connected but think problems in the HU can be on the pre-amp side so not a real gain on putting an amp.

Before I go through the trouble of installing it would be good to have others experience.

Thanks!

not in the arrays.xml file, you would just create a dead reference. but if anyone on the thread is fluent in programming in SMALI, then it would be possible to switch the lists around or even better make them identical.

[MTCB Android Head Units Q&A] typos1:
Upgrading is a good idea and lots of us emailing the sellers for the upgrade is also a good idea.

But I think you are a little harsh DSA, my friend, when you say "obsolete" - their idea is that they have 2 types of unit, a cheaper dual core version and a more expensive quadcore version, this is similar to other Android devices -phone and tablet manufacturers have several versions, often base, midrange and top of the range. :)

---------- Post added at 11:29 PM ---------- Previous post was at 11:26 PM ----------

It is the same as with any other headunit in that respect, it will only sound as good as your amp can make it sound, you can also improve the sound quality with Viper4Android if you dont like how it sounds. If you have an amp connect it up and see. I m not aware of any problems with the use of external amps, I use an OEM external amp with mine, but I did not try it without it so I cannot compare.

So I decided test it on my own car: Golf mk7, contacted this company: Shenzhen Kai Ge Le Electronics Co., Ltd

They tell that sell HUIFEI car DVDs, talked on skype with bingo Qiu, her was honest, told that had too many problems with canbus functions on golf 7, it was about 3 month ago, I keep contact if it was fixed, aways her said that not yet, but today said that it is fixed and it will arrive on 15 July (next month), as told never seen any android 4.2.2 running interface to show fuel consumption, door status, parking, etc, aways see same android 4.2.2 pictures,never showing car functions.. Bingo Qiu told me that will send me pictures of these user interface (related advanced can bus functions) next moth.. My mean question is: somebody here have advanced canbus functions working with your car ? Like fuel consumption, door status, ESC ON/off, etc ? Have an picture of this car info running over android car DVD ?!
