Hi,

Is your unit is KLD?

If I understand from the photos you attached, you connected the external mic wires (black and white) directly to the bluetooth card instead to the main board. Correct?

Thanks.
[MTCB Android Head Units Q&A] webdude12:
Most of the apps are in the play store. Looks like they are artificially blessing it. I havent figured out how yet, The apps that arent compatible are because of screen resolution. Many new apps have a min screen resolution setting to appear in the play store. This can be fixed with Market Helper or sideloading the app.

What I have done is create a folder in my Google Drive called android, then put any side loaded app I want in it from desktop, then open it in Google Drive on the unit. Works beautifully. The apps will then even update through the play store if they are free, non-hacked apps.

I havent tried the DVD Player out yet, so I can not speak on it. As a CD player though it works fine.

The unit does have an AUX in with 2 RCA (Left and Right). Simple RCA to 3.5mm cable gives you mobile phone input.

I only have like 2 songs on my iPod, but plugging it into the USB port and launching the iTunes app on the device worked fine.

Steering wheel integration works fine. The piece from PAC should allow the sounds to come through the speakers just fine, if you want them back.
[MTCB Android Head Units Q&A] shadowmyst87:
Again thanks!

I believe the description on the sales page said it has 4 channels, is this correct?

I'm guessing it probably doesn't have sub preamp outputs?

How's unlocking the bootloader going so far? Are custom roms in our near future?
[MTCB Android Head Units Q&A] webdude12:
It does have 4 RCAs, also does have a SubWoofer output.

I have not gotten my car back from the shop yet, so cant start playing. Here is a very good thread on the RockChip file structure, etc.

http://www.freaktab.com/showthread.php?287-RockChip-ROM-Building-Tips-and-Tricks-by-Finless

We will need to dump the bootloader, then analyse to see if its encrypted, or just locked, or what. From there we will know our next step of attack.

Custom Roms are a long way off. Tweaked Roms are closer to our future, but still got a way to go. Need some other hackers working on this unit and not the AN-21U. :)
[MTCB Android Head Units Q&A] shadowmyst87:
How did you guys get away with only buying one unit? All the stereos on their website says a minimum order of 4...
[MTCB Android Head Units Q&A] nwskipro:
you can try contacting the seller and asking. otherwise webdude bought his through another vendor that sells single units: http://www.aliexpress.com/store/205.../store/205122&cv=11032041&af=cj_6149808&vd=30
[MTCB Android Head Units Q&A] shadowmyst87:
Thanks. This seller is selling the same identical units as KeyLo. Right?
[MTCB Android Head Units Q&A] nwskipro:
Yeah, that's my understanding anyway!
[MTCB Android Head Units Q&A] webdude12:
Ok, I got TWRP Recovry installed. But because of the locked bootloader, can't really do anything. All the partitions are locked. But one step closer right?
[MTCB Android Head Units Q&A] gangsta101:
Dude, you're flying. Keep it up. Do you need some beer?:cool:

But seriously, have you tried pulling stuff using ADB? You could try it wirelessly and see. This way, you could get more access. Also does TWRP allow you save a backup to sdcard?
[MTCB Android Head Units Q&A] getehem:
Here as well, they are european, not chinese : android-caraudio (dot) com, there is a page android 4.2.2 with the same units
[MTCB Android Head Units Q&A] webdude12:
I havent tried ADB since rooting, but before rooting something was blocking it wireless, I do not know if they implemented the whitelist feature of it or what. Now that we have Root, thats on my list to investigate.

TWRP does allow you to put a backup on the SD Card, the problem is because of the locked bootloader partitions like /system /data/ etc are not mountable in TWRP, so therefor cant be read.

Wish you guys would hurry and get yours, so we can all play together, :)
[MTCB Android Head Units Q&A] gangsta101:
I checked out your site, they are chinese made units friend, just customized for European and Japanese cars, but they seem to carry a higher price tag than the Aliexpress sellers (not certain, but just from a cursory glance)

I am most likely gonna end up buying one before my car arrives. That way i will have tweaked it and gotten it all set before installation. But the present unavailability of units is sort of like a turn off.

btw, i don't know much about 'locked bootloaders' to be honest, but installing a root explorer like ES file explorer, would that give you 'read' access to ALL the system files, do you think?
[MTCB Android Head Units Q&A] getehem:
yes, these units are from HUIFEI as well. Their prices might be slightly higher, the shipping fees are however included. And they speak french ( for me this is easier)....
[MTCB Android Head Units Q&A] shadowmyst87:
I'll probably be getting mine as soon as KeyLo emails me back with a compatible unit for my car.

Do these stereo's have any hardware video acceleration? I won't have problems viewing 1080p videos will I?

And who is responsible for releasing updates for these units, is it the manufacturer? Will they be regularly releasing updates? Any chance they will ever release KitKat for them?

On a side note, I found this Android 4.0 double din stereo on eBay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=321184153604

It has a removable tablet that sits in a docking station on the head unit. Pretty interesting, I was wondering if anybody here has ever seen or used it before. The tablet removes to reveal a standard double din stereo faceplate underneath. It's sold by a company called xtrons.com They have a pretty professional looking website for a company out of China. They even have support forums.

Thanks
[MTCB Android Head Units Q&A] webdude12:
ES File Explorer, or my Favorite Root Explorer does give access to the android files, but not to any of the direct hardware files, like the kernel, etc. Its these files we need access to, to be able to unlock the bootloader so that we can flash new roms to these units through recovery.

Otherwise, we would have to have the signing key from HuiFei to sign our own roms to be able to load them. Until we can unlocked the bootloader, the best we can hope for is on device tweaks directly. Like for example, I was able to un-install Google Maps, Chrome, etc and re-install them form the app store. Now that they are out of /system/apps/ I have complete control over them. And when I hit the GPS button, Google Maps pops up.

I am working on Getting the Google Now launcher working, so that we can say "Ok Google" to the radio, and then launch any app, search the web for anything if you have mobile data connected, etc. But it appears part of the core android files are missing. Normally, I would just flash these in via Recovery, but since thats not an option, its a tedious process of copying them 1 by 1 into the proper place, then setting proper permissions to the files so they run correctly. This is no longer a 20 second fix, but could be hours to fix and fix right. And even then, it only works for my unit. I cant provide you guys a quick way to the do the same thing.

This is why unlocking the bootloader is key. I did try to reboot to the bootloader and all I got was a black screen. I do not know if that means it will not boot into it, or they are just hiding the output to it and I have to connect my computer to the radio and probe. Bootloader access is not available via wifi, so really need to pull the radio apart, and see if there a USB header on the main board we are missing, that will allow us to connect to this unit directly.

Photo of back of unit

Thank you for everyone who has contributed to this thread. I've ordered my unit because of what has been discussed here.

I hadn't seen a good picture of the back of the unit anywhere, so I thought I'd contribute one that the manufacturer sent me.
[MTCB Android Head Units Q&A] Zittermann:
Nice thanks, which of the units is this?

Does the KGL-7630G also have a MIC jack on the back?
[MTCB Android Head Units Q&A] jereid:
I got this sent to me directly from the manufacturer, so I am not 100% sure, but I believe it is a KGL-746 from the context of the note. There is a 15-day production lead before order shipment on the one I'm getting, so I don't think it is my actual unit which would be a KGL-7630G. I'm thinking they all have standard back and frame with different front bezel and hardware.

The model numbering is a bit hard to decipher with all of the variations.
[MTCB Android Head Units Q&A] storm83:
Does anyone know if the steering wheel controls work with apps outside of the default radio apps? (i.e Google music, Spotify, Poweramp). I think with the an-21 you have to back out of the radio app or something like that too get them to work. I was just wondering if this was the same type thing...or if they even work like that at all on this deck.
[MTCB Android Head Units Q&A] webdude12:
I have updated the wiki with 2 new files. First one is a break apart of the Factory supplied image into their own individual images. The second one is a rom dump of the system folder, recovery and boot images. This might be useful to some for creating custom recoveries, breaking apart boot.img to unlock the bootloader etc.

If I install it and I don't like it, can I go back to my original version? (v 1.77)
[MTCB Android Head Units Q&A] xrapidx:
It seems to be a little slower at times, but not much.

Startup seems faster to the main screen, but not much functions for awhile, so its probably slower starting up.

Wow, I'd love to test it. I have a firmware version sent to me by Hanker Yu as well, a few days ago, but couldn't really test it because of TWRP and my own ignorance.

Does any of you guys know how to flash update.img and mcu.img using TWRP or adb? I lost my first nandroid backup with the original recovery, so now I can't really follow the "normal" procedure :(

Thanks!
[MTCB Android Head Units Q&A] kwalsh24:
My guess would be to follow the update procedure listed on page 1. It states the difference in the two files, just as Ric mentioned

My luck however has been short, i cannot get my system to detect the update files, neither the gps card load or the sdcard copy&reboot works

Only way I got my unit to update was booting into recovery and flashing it that way with the files on the sdcard

: https://drive.google.com/file/d/0B4ofQRtnwv50dkIxWlVvbDVzUEE

For BMW e46, after the update you must enter in Factory Settings (Password: 126) and setup the logo to BMW and from the Volume tab, you must select the Sys volume to +10, then hit Apply button. The settings will be set from the next reboot.

BTW: I managed to solve out my problem with the unit not reading songs from USB. I changed the USB stick and nw everything is good.

Dear my friends,

I have recently buy my Android KGL device, and I would like to say that I was much more satisfied with my old Wince device purchased from AudioSources.

I know that this is not right place for this kind of discussions, but I think that ours devices are not finished for end-users.

WinCe boots in few seconds, and all features you have works like charm, or as it should work. Only one problem I had with my WinCe device was that after 13-14 months Bluetooth device has stop to work. I have contact Audiosources and they told me that I can send device and that they will repair for free. I did not do that, while shipping was expensive. For that price I could buy new HU.

I have decide to give my old HU to my father, and to buy Android HU for me.

First impressions war pretty good. 7 inch display vs. 6.2, than I have to try to install it in my vehicle, but HU was 5mm longer as old one and does not fit because of Air Condition. Ok, you can solve it, but you need hard to work.

Than comes problem with Sygic. Ok, I have figured out what is problem and I have explained it in this post http://xdaforums.com/showpost.php?p=61164396&postcount=13661 If anyone needs more explanation I will help.

Than comes another unpleasant surprise. I have previous installed headrest monitors and with previous unit I can normally play movies from DVD or from SD card, and I can use navi on main screen. Navi volume I can hear from front left speaker, and on other speakers I can hear sound from played media. With Android device you can only play DVD to headrest monitors. That means that I have minimum 64GB of storage only for music, and that I have to had big collection of DVD cartons for my kids when I have to drive aprox. 1.500km in one way?

Today I have tried Sygic and Igo on the road. When I use Sygic and when software tells me where I have to turn, music is muted and after speech there's one second pause. I have to add that Sygic sound is horrible. With Igo works normally.

I have told that already, but I think that software is not finished yet.

Jeez yeah ! What hes quoting isnt even relevant to his question !!

DSA's firmware is anything on the fileserver from about March onwards.

Thats a mis-translation of "freewheel", though quite why anyone would want their volume knob to do this I dont know.

No, likely to be something with the letters K, Y and D in the title, though ! Try Googling it to find out ?

"Wheel3" was just mentioned, "Rudder" is LHD/RHD, think everything else is self explanatory.

Thanks for letting us know about the update. FYI - theres no such thing as an "RK3066 MCU" - MCUs are the same for ALL versions, whatever processor or screen size you have.

MCUs are the same for all versions, see above.

No, Amlogic is a chip manufacturer, like Rockchip, they are deffo NOT the maker of the "MX" versions.

"Back online" ?

Freescale is also a processor manufacturer, their chips are used in lots of things. You appear to be searching processor manufacturers, you need to be searching car stereo manufacturers !
