[MTCB Android Head Units Q&A] Blaylock1988:
I am in the market for an android based head unit and my criteria have narrowed me down to a unit that must have at least 1024x600 screen res and at least have Jelly Bean. The HuiFei unit looks promising but I haven't seen a couple things totally answered.

- I know it has a SWC mapping app, so this app should make the SWC controls work for 3rd party apps like PowerAmp? (assuming I have the correct hardware and connections)

- I have over 80GB of music which I use an iPod classic in my current stereo, I understand that the HuiFei iPod interface is atrocious, and this unit has a 32GB limit with SD cards, so will I be able to use an external hard drive (say a 128GB SSD) plugged into the back?

Also, has anyone seen this new batch of China-Android head units? Usually I can tell which type it is from the interface and processor, this Metro-Brown interface is all new and I don't see any threads on this. It is very clean and pleasant, but no hands-on reviews yet.

With a $15 Class 10 32GB SD card and external, self-powered hard drives, CD/DVD players are pretty much useless in car stereos today.

As long as the SSD is self-powered and formatted as FAT32, it should be ok.

Everything I have seen with that brown user interface has had a Mstar 1.0 Ghz Dual Core in it. Maybe they are upgrading. :)
[MTCB Android Head Units Q&A] lucky-jon:
Agreed.... but once in a while an old DVD or even a CD that you haven't ripped finds its way to the top of the desk and nice to have an option to play in-car. Especially if it is as easy as sticking an old external drive in the glove box.

This is a CAN Bus compatibility issue, it is nothing to do with KK. you need to latest KGL MCU update, which MAY sort it, until then you ave to live with it, others have the same problem, but at least you now have KK. I m sure there is a KGL version 2.06 somewhere.
[MTCB Android Head Units Q&A] agentdr8:
Do you mind sharing your su injection method? I unpacked the KK image and tried the same with the latest SuperSU, but couldn't figure out how to change the selinux context of those files, per the updater-binary comments. Also, there doesn't appear to be init.d support built-in, so where are you launching the daemon from?
[MTCB Android Head Units Q&A] devilsoft:
Yes, KitKat works great, besides Radio App, which acts very strange when looking for Radio Stations. The freqvencies don't match at all, but fortunetly, i never use Radio at all. The graphics looks much better than any prior version too. Regarding KGL MCU 2.06, can you help me with that please? I didn't find it anywhere :(

[MTCB Android Head Units Q&A] coudu:
Ok here it is : KLD2_KK_800x480_141110_rooted_light !

As I've already said there is less bloatware/unwanted google apps than in 4.2.2 FW.

I've removed all apps that are available on Play Store :

- Gmail2

- Maps

- GoogleSearch

- VoiceSearch

- Talkback

I've also remove Chinese and Japanese Keyboards and Navgear app.

I've updated Google Play Store and Google Play Services to the latest versions.

I've added AOSP Browser bookmarks sync.

I've replaced flash_image binary with a multi-call binary with dump_image symlink so we can dump/flash whole partitions (e.g. userdata, kernel, recovery, etc)

I've pre-rooted the image with ClockworkMod's Superuser apk, binary and daemon.

I tried a modded recovery that do not wipe data but HU refuse to boot with old data from 4.2.2 so I left the recovery unmodded and IT WILL WIPE YOUR DATA so backup first!

KitKat update also seem to wipe internal sdcard so backup things you have there and put the update image on external sdcard or usb before flashing.

Hi everyone...

I'm new to the Radio business. I have some experience with mobiles, but none with the Radios. There are some things a little different.

I carefully read the first post, but there a some things uncler.

Do i need root to update the mcu.img file?

I tried it without root in both folders and no popup came out to make an update. Any solutions?

My Radio is the GS C0219 --> This at Ebay

Thanks in advance for some tipps :)
[MTCB Android Head Units Q&A] coppertop2000:
Thanks. Installed and playing with it now. One thing I've done though is modify or repartition the internal memory to better suit my needs. I've made the internal memory 3gb vs 1gb as I was constantly getting warnings about space running out.

I'm no expert, I just found some instructions online regarding modifying the parameters file in the update image and used rk image tools to do so. It looks like it worked

If anyone needs the update with the larger internal memory mod, let me know. I will update it once I've tested it for a bit to make sure there aren't any issues.
[MTCB Android Head Units Q&A] mcgworld:
the easiest way is to have update.img and mcu.img on the root of the sdcard, and you have to use the gps card slot.

the system will update plus the mcu after that
[MTCB Android Head Units Q&A] Theteenystar:
Thanks for the quick reply.

I already tried both solutions. That one you're speaking of and this one

None of those work for me :( But i only found the mcu.img and not the update.img

Do i need both files? the mcu i found here : https://drive.google.com/folderview?id=0BxmzvLRI7-eNeVA2SWkwM1pLZ28&usp=sharing#listv and i took the last one GS 2.08

Where do i find the right update.img file?

Sorry for those questions but its not easy to find all the specific files between all those different models.

you can use any system update, because the android side is interchangeable, except resolution wise, must be the same res 800x480 or 1024x600

what version of MCU you had before update? KGL4 or KGL?

I have KGL, but I am not sure if I can use the KGL4 2.09
[MTCB Android Head Units Q&A] typos1:
Great news.

What was your problem, what is your car ?
[MTCB Android Head Units Q&A] devilsoft:
I tried all MCU (1.77, 1.86, 1.99 and 2.03), KGL & KGL4, but none of them worked. My problem is described here: http://xdaforums.com/showpost.php?p=56745363&postcount=4794

Now that problem is gone, and I also run KitKat (rooted version), and everything works perfect :)
[MTCB Android Head Units Q&A] typos1:
The MCU image in the 1024x600 is for all KLD versions, agentdr8 is putting a copy of it into the 800x480 download as well, but it is the same for all KLD units, whatever screen size.

Yes, I and others have tried the MCU and it is fine, but the unit in the link is a "JY" unit so DO NOT use this MCU, you have to wait for a new "JY" MCU update. To check what version you have go into the "about" screen in settings and look, pretty sure yours will say "JY"

SWC and CAN Bus are unaffected by the update.

coudu has uploaded a pre-rooted 4.4 update a few pages back, put that on your unit, DO NOT use the MCU image if your unit is a "JY" unit !!
[MTCB Android Head Units Q&A] devilsoft:
Hi typos,

My car is Opel Vectra C (2008), with a KGL4 unit, and my problem was, that my small car display didn't worked well, only when I reset from the small RESET hole, and lasted until I restarted the device.

This is the video which describes my problem: https://www.youtube.com/watch?v=AXSlXCBebW8. I'm talking about the smaller screen, which needs to display the unit information, like Music, Media, Radio, etc.
[MTCB Android Head Units Q&A] typos1:

---------- Post added at 11:13 PM ---------- Previous post was at 11:12 PM ----------

Yes I saw the video earlier today, basically you now have two way CAN Bus working ?

That is good, previously it only worked on some VWs.

Anyone know which wires on the DIN plug are Tx and RX on a Klyde ? I m gonna try connecting the unit directly to the CAN Bus.

Yes, now I have two way CANBUS, but only with KGL4 MCU 2.09

Its great to see we have an update. I am so slammed with work these past few days I havent had time to play at all. But now that I have an update for the 4.4.2 - 1024 x 600 KGL unit, in the coming weeks I plan to do several things with it.

Root the image

Remove almost all apps to keep /system/apps as clean as possible (keep the ones that relate to the system itself)

Deodex it

Fix the 1024 x 600 resolution to use the full resolution of the screen, not 1/2 of it

minor tweaks
[MTCB Android Head Units Q&A] typos1:
Yes, I could see, I just did not realise that you had RDS in the US.

---------- Post added at 11:28 PM ---------- Previous post was at 11:25 PM ----------

Ah, was meaning to ask you whether your new unit was an RK3188 one or an RK3066 one, guess its a 3066 then. (Re read your last post, I knew there was something different about your new unit, its the screen res, not the processor, you got 1024x600).

I remember you couldnt get root, did you figure our how to ?

Cos as youve probably read we got root on 4.4 now.
[MTCB Android Head Units Q&A] leo524:
Can u pls post the larger internal memory mode thanks
[MTCB Android Head Units Q&A] webdude12:
Yes mine is the RK3066 and its from KGL. I never could get root on 4.4.4. ADB also does not work at all. The screen resolution is just scaled from the 800 x 480, so no real benefit of having the 1024 unit

But with an update image and some time, I can fix all this :)

I've attached my 'modded' version of the recently uploaded pre-rooted 4.4.2 800x400 update.img.

It is exactly the same as originally uploaded, with the exception that I've increased the internal memory to ~3GB, which has obviously decreased SD card storage.

I've tested it so far and I don't seem to be having any real issues related to the 're-partitioning'.

One thing I had to do while updating today was format/erase the SD card partition from the settings menu. Not sure if everyone will have to do it based on the SD card size changing. Once I formatted, it showed up properly.
