If you plan on going to 4.4.2 from 4.2.2, then there's no reason to root 4.2.2 as it will get wiped anyhow.

Pick one of the pre-rooted 4.4.2 images and flash that. You can use any of the system images on your JY. Just don't flash any non-JY MCU images.
[MTCB Android Head Units Q&A] typos1:
It has shown up - coudu has a 1024x600 copy and he ll root and make an 800x480 version "this week".

The apps do look good on 4.4.4, not sure about the stupid picture of a record on the music app though.

---------- Post added at 06:35 PM ---------- Previous post was at 06:33 PM ----------

With Android you can have any launcher you like, 4.4.4 hasnt been tested yet, but its highly likely that your ll be able to use the Kld 4.2.2 launcher on it.

That's excellent news, I use poweramp so I'm not bothered about the music app. I just hope the bluetooth issues are fixed in it as well.

[MTCB Android Head Units Q&A] agentdr8:
I think it's supposed to be a speaker, not a record ;)

Either way, a waste of screen real estate imo.

I use media monkey anyway, as I prefer to see the album artwork
[MTCB Android Head Units Q&A] typos1:
Yeah it does look like a speaker as well, but some of the previous music apps had records on including a needle and an arm, so thats why I took it as a record, either way, its sh*te, have to remove it asap !

I like the stock music app now it plays flacs, simple to look at easy to use, tried loads of music apps, including poweramp (which supposedly had a 15 day trial, but it only lasted 3 days !! WTF ?).

Each to their own, thats the beauty of Linux, highly customisable . . . or not in my case, lol.

Coudu did say there is a revised BT stack so hopefully, BT OBD will work for those who dont wanna use USB to OBD.

(Thats the THIRD time a link to the 4.4.4 video has been posted, cant people be bothered to use thread search ? Why do they expect the regulars to do basic stuff for them all the time ? !)

How do we use the KLD 4.2 Launcher and Apps (radio, music, dvd, etc) with the 4.4.x roms?

Is there a repository to get these files or do we have to pull them out of a working rooted unit? If so how/where/what is needed?
[MTCB Android Head Units Q&A] ultradj83:
Well I entered the menu and the job is done.

Maybe there are more passwords to do different things, what if I need to do a real factory reset as example?

I see there's a lot of stuff, I'd rather to understand any of the options, some are easy to understand, some others arent's: I'm not searching for information about CAN settings (I may solve a problem that makes me connect and disconnect my OBD adapter a lot of times any time I need it to work) and about DVB-T, I have an external decoder installed but I'm actually unable to use it, because this firmware I have has no DVB-T app.

By the way, I'm going to try several firmwares, I may also write a new post to share on this 3d details about any firmware in order to make clear the differences in order to help everybody to choose.

Do you know the difference between KGL and KLD firmwares?

Thanks a lot.
[MTCB Android Head Units Q&A] typos1:
Some modified ones are on the FTP server, otherwise your ll have to extract them yourself, unless anyone reading has copies they can let you have.

Just replace the standard ones in system/app with the ones you want, have to be rooted.

[MTCB Android Head Units Q&A] mikochu:
I searched this thread for "4.4.4" and "youtube" and didn't find it. Then, I searched for a few titles on YouTube with no success.
[MTCB Android Head Units Q&A] typos1:
There are no more passwords, only 126 for factory settings.

CAN Bus and OBD are entirely different things and are not connected to each other, so CAN Bus settings will not alter any OBD problems you have. BT to OBD is not working in 4.4.2, it may work on 4.4.4 we do not know yet. To solve OBD problems its best to use USB to OBD as it is faster and more secure.

Only DVB-T boxes that are comaptible with these units will work with the TV app. ALL firmware has TV apps, they just need to be turned on in factory settings, there are 9 or 10 options. If your DVB-T box is not compatible with these units then your ll have to use the composite video of the AV-In app, which means a very low quality connection. For a decent signal you will also need a diversity/dual tuner TV box.

The differences between the KLD and KGL firmwares are well documented, just the look of the music and radio apps, the look of the file explorer apps and the home screen style and a few other minor differences.
[MTCB Android Head Units Q&A] goolac:
anyone have a list of the various APKs that are needed for transferring from one version of rom to another found in the system/app folder? (KLD 4.2.2) but this list would be good to know for all variants.

You mean to make KLDs look like KGLs, or 4.2 apps on 4.4 etc ? If so what you have listed is about right, BT app a bit different as well.
[MTCB Android Head Units Q&A] goolac:
No I was talking actual file names so as to not miss any. I have a KLD and the 4.4.2 stuff is not as pretty (In my opinion) as the 4.2 versions. Although I just watched the youtube video and the updated apps and the Multi-band EQ may be worth the switch to 4.4.4.

UPDATE TO SCREEN FLASH ISSUE:

The Red Can-Bus module says 2014 X-Tera for Nissan. The Reverse wire goes to the box to enable the 6V to the backup cam. When I turned on the Right Turn Signal and Braked the screen would flash. Turns out that the box interpreted a reverse signal every time the Blinker would blink causing the screen to flash. I was able to cut the wire from the box to the head unit for the reverse and then connect the head unit directly to the factory wiring Reverse lead. This allowed the Box to correctly operate and the backup to work, without the glitch.

Mine is also a 2014 altina.. orange from the 30 pin to the red box is the feed. Cut the orange (careful there are 2 oranges fron the head unit) the one you want is from the red box to the head unit. Cut that one and tap the unit side it into the feed. Tape off the other end from the red box and the glitch will no longer effect the unit. I swear i have not been happier.

Also i changed the antenna lead in the grey connector, from the center position to the outer and the radio reception was improved.
[MTCB Android Head Units Q&A] marlemion:
Hey guys,

I have a GS unit, but no mic input jack mounted to the rear. There are some holes in the back of the devices, which might be reserved for other models, which provide such a jack. My mic works, but it could be more sensitive. Haven't tried the microphone app yet, but that will be the first thing I will do. However, if this won't work out, I was thinking about attaching an external microphone. As there is no jack and I would like to avoid opening the device as long as possible, I was looking for other possibilities. There is a cable connector, which provides video input. It does not seem to be the one used for the reverse camera, but for another camera possibly to record the front view of the car. It provides a yellow chinch for the video signal and a red/white chinch for the audio signal. Could the latter be used to attach an external microphone? And how would I 'talk' to it within the system?

Thanks for any info!

[MTCB Android Head Units Q&A] typos1:
Your only option is to open the unit and wire in an external mic, its been done several times by others, use the thread search to find out how.

I ve added a copy of the KLD 4.4.4 1024x600 res, non rooted to the fileserver on the first page. coudu HAS NOT worked his magic on it yet, so no 800x480 res and as I said its non rooted, if you want 800x480 and root then wait for coudu's version.

Just got this reply to a post on 4pda.ru (translated):

Now the work day will end I will go to put. rebuild the image with the kernel.img (800*480) from 4.4.2 and root, tried to put as you did for 4.4.2. Can start. Content ramdisk'a not much different. The difference is one line in the init file.connectivity.rc. Zakomentiroval line:

[MTCB Android Head Units Q&A] pakidermo5000:
There's but needs some work. I think that in principle it sould be done by the CANBUS decoder, but my CAN BUS decoder s*cks and does not understand anything. I have an A3 from 2005 (it had 1DIN radio, and swtiched to 2DIN).

YOu need to find the connector under the steering wheel that corresponds to the key. (In my case, the unit was not entering in rear mode, so I had to take the connector for rear gear from there and connect it to the rear gear pin of the unit, not an easy task as the fuse box is quite well hidden). Then you can use it to build a logic door with the constant 12V pin so that the unit would only turn off when the key is removed, but on when the acc is on. you can find diagrams of the pins under the steering wheel (and behind the fuse box) on line.

Ive powered the unit via an ATX powersupply

Its lovely,

-Plex works like a charm

-USB HDD works!!!

-Huawei E3131 (enternal antenna) works

So far i have one question: I was expecting 4x RCA audio output

But on the RCA plugs I only have out Rear left and right.

The schema on the device also shows Out front left and right.

But these pins are not connected/present. But do these pin outs work ?

Klyde, like KGL and RM etc, also make WIN CE and "dumb" hea units as well. The cAN Bus boxes are specific to each car, but not to the headunit, if you look, you should see that teh CAN Bus lines go straight to the headunti to the car, the CAN Bus decoder simply gets park, reverse, speed pulse, SWC etc from teh car to the head unit, AFAIK.

When you get you unit I wonder if you can help me with something ? I am trying to find out which wire is CAN Bus Tx and which wire is CAN Bus Rx from the headunit, I know which 2 they are I just do not know which is Tx and which is Rx.

Also, I have a problem with the launcher and Torque widgets, on every version 4.2, 4.4, 4.4.4, all of them will not show all 3 Torque widgets -(a big gauge, a little gauge and an OBD toggle) only the OBD toggle show up in widgets with the built in launcher, but other launchers show all 3, its really annoying and I cannot work out why, anyone got any suggestions ?
