please help.

I just bought an 8" unit for my Prius. I would like to root it but im a little confused. The unit is KLD RK3066 running 4.4.4. From what i'm reading I would have to in use a coudu image. With my unit being 8" will it work?
[MTCB Android Head Units Q&A] Alphas:
You need to check the screen resolution, and update with the correct dual core and resolution image.
[MTCB Android Head Units Q&A] KEHT:
Hello guys,

I had a quick question. I'm considering one of the KLD units offered on alibaba. While I was doing so, they suddenly came up with a new version that supports MirrorLink and charge $90 more for it. I was under the impression that MirrorLink was a software feature?!?! Any thoughts?!?!

[MTCB Android Head Units Q&A] typos1:
No, you do not have to use a coudu image, DSA, coudu and Malaysk have images on the fileserver (DSA and Malaysk have them posted in the thread as well), you can use KLD, KGL, or JY.

The screen size is irrelevant, you use an image that is the same resolution as your screen.

Yeah, so was I, or ta least some sort of screen mirroring software, mine has an app, but never used it.
[MTCB Android Head Units Q&A] nzdreamer55:
This should be an easy answer for your guys. I want to learn about controlling the programs that start up when my headunit starts. Could someone point me to the correct info (wiki, specific post, etc?) I know I need to modify a file, but am not sure where or which one.

Thanks in advance.

[MTCB Android Head Units Q&A] agentdr8:
I'm pretty sure at least in older versions of MTCBackView that "reversing the trajectory" enabled/disabled the lines, and "reverse x-mirror" flipped the image. Either way, even if you get lines enabled in the android-side, it won't affect the reverse view when the MCU is handling it (like during boot-up).

Try the option in Waze to output sound via phone speaker. Or if that's enabled, try disabling it.

Just installed a headunit for my mitsubishi lancer which I bought here:

http://www.ebay.com.au/itm/171763522053?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT

Can someone point me in the right direction on how to root this? Reading through the first post looks like I need to flash pre rooted ROM since I'm on 4.4.2, just not sure which one I should flash?

Also having trouble with the stock ipod app. When I connect my ipod touch or ipod classic via the included 30pin connector, the ipod app will not show any music or if it does it crashes after a while. Is there any other ipod app I can use?

Also I don't currently have a reverse camera installed, but when i put my car in reverse it will switch to the reverse camera and say "no signal". How do I disable this?
[MTCB Android Head Units Q&A] Enc0der:
I tried both options, same results...

Can someone with JetAudio and Waze confirm that this happens to him as well? I'm using Malaysk's rom if that matters.

btw, I just checked with the full version of PlayerPro, and the multiple button clicks (from hard buttons and SWC) happens to be with it as well .... I click on "Next" and it jumps 5 (!) tracks...

Maybe I should try to completely uninstall the "HeadUnit" app and then try again with XMTC alone.
[MTCB Android Head Units Q&A] typos1:
Theres nothing important on it, just install iGO, Sygic or other nav apps from the Playstore or side load them.

Any image you like, as long as its for a version that has the same number of cores yours has and the screen resolution matches yours.

Disconnect the reverse wire.

[MTCB Android Head Units Q&A] neos_83:
Thanks. What about the MCU. Do I need to update this?
[MTCB Android Head Units Q&A] typos1:
I dont have it I m afraid.

Not a have to, but Its more up to date, more features, latest ones have an interface that matches the rest of the system. Its like any other software - usually more up to date is better, though not always.

Bascially flash the latest MCU version - it ll most likely be better or the same, if you get problems go back to the version you had before.

Pretty sure its the same for all.

You dont need to, but its a good idea to, see reply above.
[MTCB Android Head Units Q&A] Alphas:
Trying update the rom first, if the unit is fine with the MCU then there is no need to update it. MCU update normally fix the bugs but update with wrong MCU could brick the unit!

---------- Post added at 08:26 AM ---------- Previous post was at 08:05 AM ----------

Look for the reset button, Power the unit, and press and hold it for 10-12 sec until the unit starts up and release the button.

Mirrorlink is just an app, AirPin Pro that can link the iphone to the unit. There is no hardware specific module that enable mirrorlink. Miracast is also support by the unit, I could project the image from the unit onto the TV, but this is pretty useless anyway.:D

RK3188 on the way

Thank you DSA for the inspirations and help with obtaining the RK3188 SOM card. I now have one on the way soon if all goes according to plan.

So does the card come with the Android ROM loaded? I am guessing not since they won't know which screen resolution my unit has. So i am guessing the procedure is to upgrade the card and boot up with the android image in the GPS slot and I should be off to the races?

Thanks again for making this possible :

-Q
[MTCB Android Head Units Q&A] nFKT:
For those of us that are getting into the game late, what are the advantages of the KLD/HuiFei units over the Newsmy units? The specs seem to be better on the newsmy end from what I can see (1024x600 screen and 2gb ram rk3188 only, two bluetooth devices) prices seem to be the same for both.

and on a different point, is anyone using WinCE/Android dual boot Klyde units? If so are there any advantages/disadvantages? I'd assume WinCE boots instantly and you have the option to go into Android? That could have some advantages as well as on the standby side if it's running virtualized.
[MTCB Android Head Units Q&A] Alphas:
Newsmy unit requires an external android box and that present other issues on the connection, firmware. It uses a firewire connection which means more points of failure.
[MTCB Android Head Units Q&A] nFKT:
But they have full source of their firmware, thus better software support. From what I can see so far the only downside is the secondary microphone is not great.

This makes it hard to know what to buy.

I'm trying to decide between a newsmy

or either a Klyde with rk3188 and upgraded screen or one of the new Joying devices.

Any thoughts? I don't believe either the Klyde or Joying have the ability to be connected to two devices at once.

I am a new owner of a klyde unit and update to mcu 2.49 and latest malaysk 800x480 4.4 kit kat.

Some things i have noticed is that whenever i turn on the car i see that i have lost the stations i had in memory and also car doesnt remember that i have left it with radio on and starts with radio closed. And general there is a sense like unit starts on its initial settings because contrast also goes to the default level.

Also illumination buttons red and blue are upside down. What i mean is if i want to choose red color buttons i have to press the blue choise and if i want blue i have to press red one.

Also radio FM sometimes get disorted like losing signal and i need to reset unit to be ok again

Power button top right corner get unit on a boot logo stuck and i need to reset it in order to boot again

And i get sygic black screen but i have seen this is a common issue.

usb-tethering / unit does often not connect to WiFi

Hello,

is there a a way to connect the HU by USB-tethering to the smartphone ? - I found this or similar questions a couple of times in the forum, but not really a clear reply to it...

Of course it is possible to connect to the smartphone by Wifi, but I have some stability issues there - often I have the situation that the HU "sees" the Wifi of my mobile, but doensn't connect to it - I think it is not a password or WPA issuem, because somethimes it works (..with unchanged settings...) - it is often like this that it works nicely, then I have a stop, and afterwards I do not get a connection to the Wifi anly longer - the Hu sees the Wifi, it states the connection is "saved", but for some reason it doesn't connect, also not when I try to force it...

- Sound for me like some kind of software problem, any ideas ?

- USB tethering might be a way how to circumvent this, but so far I haven't found any way how to realize this ...

Thank you,

Best regards,

Michael

JY MCU ugrade

What is the difference between MCU JY v2.16 and MCU JY v2.49
[MTCB Android Head Units Q&A] typos1:
It is advisable to update the MCU and only go back to a previous vesion if you have any problems. You DO NOT need to go into recovery - the unit will automatically detect the update and ask to install it. The ipod app is MCU controlled so an update MAY help sort it.

The specs are about the similar but the Newsmy has 2 BT stacks, one a normal Android one, the other MCU controlled for the phone. It does also have the option of 2Gb RAM and these units dont at least not yet. However, the Newsmy''s MCU is not well developed compared to these units and it only has 2 RCA outs and no sub out. The fact that the Android side comes in a removable box may or may not be an advantage, its down to personal opinion. There are no advantages to the dual boot unit - if you do get a Newsmy avoid the dual boot one.

It does not "require" and Android box, the box comes with it. Nowt wrong with firewire connection, its actually an advantage compared to the units in this thread.

We do not have the full code for these units, but there are several custom ROMs around despite this. The Newsmy microphone can be upgraded - as long as it DOES NOT have a built in sound card.

Thanks again Malaysk ! :)

Are you sure you have not installed the wrong MCU ?

Good 3G dongle?

Can anyone recommend to me a good reliable 3G dongle? I've read that there is a somewhere a list of compatible 3G dongles, the only one I can find is post 4038 on page 404. Not sure if that's the one or not. Anyway, any personal recommendations? My current unreliable 3G dongle has no markings on it so I can't tell what it is. I would preferably like one which allows me to alter its settings and has a low power consumption.

Edit:- must be unlocked.

thanks for the info

at the moment i have write to Jenny ,Linda and Jacky

but i think again will be without any reply

if you have additional contacts i will appreciate

I know that this AF problem is not so easy to understand where is generated first....or in MTCRadio or in another MTCservice related to the RadioApp but i really hope that somebody here will have some more knowledge to indicate the right way to start and found what to modify... Seems that the radio loose RDS data (so the name of the station) as soon signal start to decrease. In any RDS system that works properly, this data remain also if station is practically lost, so the system can identify another frequency that trasmit same data ed swap to this new frequency station.

I repeate if somebody have a good knoledge of smali language i can suppose will be able to found where is write the logic of this RDS function and rewrite properly.
