[MTCB Android Head Units Q&A] zorantoma:
Aha ok. I think it has to do something with the mcu version. I have a JY unit with a older mcu(2.16) and all works till 5.2.2015 firmwares.after that my unit cant download the contacts from the phone.
[MTCB Android Head Units Q&A] typos1:
Ah, you mean the AN21-U head unit !

Never heard it called a "Kaier" before, there is an XDA thread for it.

---------- Post added at 04:15 PM ---------- Previous post was at 04:12 PM ----------

Ah, ok, its normally called an "MFD", proabbaly to avoid confusion with OBD/OBD2.

---------- Post added at 04:19 PM ---------- Previous post was at 04:15 PM ----------

I ve always thought it was for telescopic aerial like you, it may work for boosters supposing the power injectors are the same voltage and ampage as that wire, but I m not sure if its a trigger wire or an actual power wire, I know the antenna power injectors also contain a filter to get rid of interference and using that wire would not help in that respect and I guess embedded antennas have boosters as well, try and see if your signal improves. Although I m not sure that its as simple as attaching 12v to the antenna line directly, without the filters it may actually create a lot of noise and interence

---------- Post added at 04:24 PM ---------- Previous post was at 04:19 PM ----------

Even if it doesnt provide power when the radio is off, it would still work as a power injector (filter excepted) as you would only need it when the radio app is running !

The power injector allows an "active" booster to work on cars with OEM active antennas/boosters

I knew that what you had read had made you paranoid about it !!

Now you know the facts about the cylindrical power injectors, you know not to buy one again, you can buy any booster with confidence now, if you refuse to buy one unless someone shows you pics of it opened youre likely to be waiting a long, long time before you get any radio reception, no one is going to open their product just for you. And even if you bought another that was just a power injector (unlikely now you know what you know) you could open a dispute and get a refund. I understand your annoyance at being sold an incorrect item, but you have to think of all the people reading this thread, our job is to keep them correctly informed and your negativity towards this matter may not do this - some people may be put off buying one of these devices when it is EXACTLY what they actually need and as a lot of modern cars DO need them because antenna boosters that require power from the headunit are used on a lot of modern cars, more people are likely to need one than not. :)

For clarification:

The cylindrical power injectors are perfectly legitimate AS LONG as you have an OEM antenna booster that needs power from the headunit.
[MTCB Android Head Units Q&A] OBeerWANKenobi:
Yup, agreed. My point was only to mention the differences between an AMP or remote wire (usually solid blue) and a ANT or power antenna wire (usually blue with white stripe).

Desktop power-up

Is it a way to power-up the unit without physical buttons on desktop?

It's about A7047 (Chevy Cruze) unit.
[MTCB Android Head Units Q&A] typos1:
"A7047" is useless for identifying your unit, we need manufacturer eg KLD, KGL, JY etc

If its buttonless it ll probably be a JY.

None of that is relevant for your question anyway, you power it on a desktop the same way you would any other car stereo - connect the battery and acc to a 12V power source's live terminal and the black to the negative terminal, if its buttonless and you want the LEDs to light up then also connect the orange illumination wire to live.
[MTCB Android Head Units Q&A] matekhr:
Ahh, I see, you need more info.

It's a KLD unit, not buttonless, but Cruze has separete plates with radio controls as well as HVAC controls. They need a canbus decoder to operate. It works OK in a car, but for the first time after connecting it, I have to press "power" button to power it up. After that it is enough to connect ACC (red wire), as long as BATT (yellow wire) is connected, to operate the unit. After disconnecting/reconnecting the yellow wire, "power" button must be pressed again to operate the unit.

As you can see, I dont have the "power" button whent connecting it on the table... :(
[MTCB Android Head Units Q&A] typos1:
Ah yes I ve seen those units, the screen is high up on the dash and separate. I dont know, I guess you cant if theres no power button.
[MTCB Android Head Units Q&A] giornistrani:
Hi guys

Hello guys, I bought a car radio for my Opel Astra J with Android 4.4.4. The original Rom has changed the language of the on-board computer of the car so I contacted the seller who told me to install this Rom: update_4_4_4_1024X600_KLD_3_MAL. The problem is not solved, I still have the onboard computer in another language and I also lost all steering wheel controls and the keyboard car. I ask you help please, I do not know what to do. Thank You:(
[MTCB Android Head Units Q&A] matekhr:
Hm, I'm not glad to hear that... :(
[MTCB Android Head Units Q&A] giornistrani:
hi

hi can you help me please?
[MTCB Android Head Units Q&A] typos1:
For ANYONE who has a car with an OEM antenna booster they are essential, not just me, I just want to make sure that people know that and that the devices are ok AS LONG as you have an OEM booster.

I fully agree that they should be advertised correctly and understand you being annoyed, I just want to make sure that people know the facts.

The guy who "warned" about it now knows that facts but refuses to acknowledge them and now he is just as bad if not worse than the people who mis-sell them as boosters - they do it out of ignorance, he does it out of pig-headedness and he is perpetuating mis-information, just like the mis-sellers.

Anyway, I ve made my point, I dont wish to go on about it (anymore than I have already lol) or fall out about it. :)

---------- Post added at 10:24 PM ---------- Previous post was at 10:20 PM ----------

I m not sure we can, unless someone with a GM car has experience, AFAIK most cars the language can be changed from the menu buttons in the car, a previous poster suggested you need "MDI" (presumably a GM specific car comms device/software like VAGcom, AlfaExamine, FiatECU Scan etc etc) to do it, or you have to take it to a dealer. If this is correct I would open a dispute if I failed to find info about changing the language without going to a dealer.
[MTCB Android Head Units Q&A] pants001:
Correct, I read that from the front page but it appears to be the contents of the startup script (Which will be helpful down the track)

But is there any info for how to create, adjust these settings.

Is it just a case of being root and editing an already existing script?
[MTCB Android Head Units Q&A] jkchr1s:
It only improved sound quality for android apps, the FM radio sounds like crap for me.
[MTCB Android Head Units Q&A] agentdr8:
You just need root, and the ability to edit /system/etc/install-recovery.sh (either via terminal, adb, or an app such as VimTouch).

As for what to put into that script, it's different for every app you want to start. Finding either the proper activity/service to call or the intent to broadcast is left to the individual to figure out. Common apps are listed in the above-mentioned post, but not-so-common ones would have to be discovered either by trial-and-error using the am command (and maybe watching logcat for debugging), or via a manifest dump via apktool/aapt/etc.

[MTCB Android Head Units Q&A] RyanBRZ:
I recently updated to Coudu's latest ROM (800x600 150115) and it no longer has the default home widgets; clock and variable widget depending on what you are doing (weather\music\radio\bluetooth). Is there any way to get this back because I miss it.

The new one has larger icons on the dock and it looks very different. Is this maybe the wrong firmware, or did he change it with the latest?

Here's what I used to use., and want back.
[MTCB Android Head Units Q&A] AKCPE:
Hi. I'm newbie here. I've just got it 2 days ago and I want to root it. I read many pages in this thread but I think I missed something.

How can I find the pre-rooted original update.img? I don't want to install the custom FW. I hope there are someway to install SuperUser without installing the new image.

Does anyone have the issue with IPOD app? I open the app and plug in the IPOD cable to my iPhone then it crashed everytime.

And is there the way to use 3G dongle without root? I installed PPP widget 2 but it showed "No modem found". There is the signal quality icon on taskbar but I cannot access the internet.

Thanks in andvance.

Does any WiFi adapter work with this unit?

I hear the range on the built in WiFi is kinda bad so I want to use a USB WiFi Adapter from a local computer store.
[MTCB Android Head Units Q&A] Petrows:
You are right about nearewst future, but there are some reasons to do that:

1. i had published new app for RK3188 headunit already. The new devices named C200 by Ownice: http://www.ownice.com/ . They are not compatable with our micronteck and required new app. Universal app is not possible for both MTC and Ownice units :( RK3188 app page on goolge play

2. People dont know what is "Micronteck" or "Mtc", these trademarks are not listed in end-user headunits anywhere. These headunits are known as just "RK3066 headunit" or "Noname RK3066 headunit", and new name more targeted.

But i agree - if there will be micronteck-based units on RK3188, the app should be renamed for some just more univeral, like "RK3066/RK3188 headunit".
[MTCB Android Head Units Q&A] Ascona20:
Hi, if you zoom at board, you will find the residue. Is it near little chip. There are some conductors and transistors at one line...

Maybe you can help me and send me detailed photo of your board (if you have same version of board).

Hi, guys! First of all, THANK YOU so much, finally I rooted my NAVI radio car with a Coudu rooted firmware. This thread are awesome, I will keep an eye on it :good:
[MTCB Android Head Units Q&A] RainesX:
Hi.

Since this thread is so huge i just go and ask (yes i have searched and read some ofit but cant seem to find my answer.)

Im thinking of getting this here unit. http://www.eonon.com/Car-DVD-Players/Android-Car-DVD/G2110ZV.html

a eonon G2110ZV (same unit and price as the non v one but upgraded to 4.4.2 so i dont have to ^^ )

Well my question is if you who have this unit are pleased and if it is possible to just plug in and use or if you have to solder/root and stuff like that. Also if the handsfree is working good or if it is so so or just plain bad (thinking of the mic)

Would also like to have obd support over bluetooth while connected to the phone for handsfree. (no idea if that is possible but if it is i bet someone here know it :)

The unit im using now is a Kenwood DDX 4023BT right now and its rock solid and have external mic. But no android :(

And thats the reason why im asking :)

Another question.

the unit im looking at have 2 usbports for 3g and usbstick up to 32gb.

Does this mean i have have a 3g modem pluged in or do i need to work some soledringmagic like metioned in first post?

would like to avoid theathering my phones internet :\

Might have more questions but thats it for now :)

Thanks for plowing trouh my post and for your time and help.

Sorry for my grammar and spelling :(

Hello Ryan, which firmware did you install, theres KLD, KGL, and JY that coudu has done, pretty sure KGL still looks like that, I d try some of the others.

The widgets from the older KGL firmware can be installed on any version, they are separate apks.

---------- Post added at 11:34 AM ---------- Previous post was at 11:30 AM ----------

The pre-rooted images from coudu and DSA are almost stock, there are very few mods, thats the only way to root, or you can get hold of the original firmware and inject the necessary stuff yourself.

I wasnt talking about the Ownice units (or the Newsmy RK3188 units), there will be Microntek RK3188 units out next month with RK3188 processors, made by the companies that make the RK3066 ones in this thread, well at least one of them has told me they will make them, I guess the others will too. I was told they would be exactly the same as these RK3066 units, with the same software, just with upgraded processors. "RK3066/RK3188 Headunit" as the title might also confuse people - some Newsmy and Ownice users may think it will work on their units :( Maybe "RK3066/RK3188 Microntek Headunits" ? ?

---------- Post added at 11:46 AM ---------- Previous post was at 11:39 AM ----------

Eonon are just re-sellers, so we dont know what youre talking about with that model number, although I think it will probably be a KYD unit, you can check by reading the first page, not that it is that relevant.

4.4.4 is the latest firmware, by the way, not 4.4.2, you can use BT OBD (if you ust, USB to OBD is better), but ONLY with 4.4.4 (well most people can, a few say they cant). You can use a 3G USB modem without need for soldering. Some people say their mics (internal and external) do not work well, some say they do, if you think they do not work well then you can do a small modification to improve them.
[MTCB Android Head Units Q&A] clearchris:
I have the non-V unit. It's a KLD. I love it.

It's not exactly "plug and play" if you want all the features out of it. For example, if you want a backup camera, it's a bit of work fishing wires, etc.

Rooting is relatively easy, I use couda's ROM. I have had no problems with the speakerphone. I don't use the external mic. I have heard of problems with the speakerphone though, I'm not 100% certain of the cases in which the problems occur.

I don't use the ODB stuff. If you want to use a 3g dongle and an external usb memory stick, using an externally powered hub is highly recommended. The unit just doesn't have the power to make it happen by itself.

Eonon as a seller is also great. They shipped really fast and the unit arrived in about a week to the USA.

Good luck and if you buy one welcome aboard.

---------- Post added at 09:20 AM ---------- Previous post was at 09:07 AM ----------

I haven't opened mine yet so I don't have pics. I haven't seen the residue on other people's pictures though.

Since there is residue at the base of the caps, that's pretty much one of two things... Flux from the soldering process (wouldn't surprise me if these are hand soldered) or leakage from the capacitors.

If it were me, I'd probably replace the capacitors. Your unit is dead, and caps are cheap. In general, the uF value should be the same, but you can increase the temperature rating and the voltage.

I think, You need a special CANBUS decoder. From production date of ~2004.... - all opel/vauxhall models built with canbus system. RK3066 HU, basicly handling analogue type of control only, but CANBUS system is digital.

You could be find something like this ( "....steering wheel stalk control interface" )for example at here : http://www.nexxia.co.uk/products.as...rs&c=Vauxhall Steering Stalk Control Adapters
