4.4.2 up? I see it listed [MENTION=1177255]270[/MENTION]megs?
[MTCB Android Head Units Q&A] ESTIMULO:
Seems to be the same android version that came with my radio from factory. I hope some one of you can root it [emoji16]
[MTCB Android Head Units Q&A] kwalsh24:
Thanks I seen that just wasn't sure of it was fully uploaded yet, 270megs seemed small

Any updates on root ?
[MTCB Android Head Units Q&A] typos1:
Maybe you d get better CAN Bus functionality if updated the MCU to the latest which is at least 2.02 for KGL

How did you root ? the latest Chinese root app doesnt do anything on mine, I just get the logo.

Antutu said it was rooted, but root checker says not, coudu says hes rooted it, but not how to.

I'm guessing I can't flash this Klyde 4.4.2 update to my Erisin ES9746A (HuiFei)?
[MTCB Android Head Units Q&A] typos1:
Android updates are compatible between ALL units - you can use any KLD, KGL, RM, GS or JY Android update on any of these headunits just not the MCU, it has to be an MCU update from the original manufacturer of your unit. So flash away, if I were you I d also try and find the very latest MCU from KGL and flash that as well.
[MTCB Android Head Units Q&A] Stank0:
Thank you. I'll give it a try. I tried the later MCUs but the newest one where my faceplate buttons wori is 1.86 but I lost the button illumination. Well I guess it's a matter of preference in this case. I'd like to have both, but I prefer working buttons over illuminated but useless ones.
[MTCB Android Head Units Q&A] typos1:
Well I d check and see if there are any later KGL MCU versions and try the latest if there are, the update also came with an MCU update that was has several extra functions and lots more CAN Bus options. I m sure the KK update on its own would work with your current MCU version though.
[MTCB Android Head Units Q&A] Boodro1:
Any work on the changes to MCU 2.08 for the GS unit?
[MTCB Android Head Units Q&A] agentdr8:
As in a changelog? No idea. Didn't seem to change anything on my GS, but I also don't have SWC or CANBUS, so maybe they improved stuff there.
[MTCB Android Head Units Q&A] tylerzipz:
Hey Guys! Reading through this whole thread, trying to figure out what device to purchase. I just bought this : aliexpress.com/item/Newest-2-Din-Android-4-2-Car-video-player-build-in-car-radios-GPS-Navigator-Bluetooth/1990842398.html

Will I be able to root? I looked at the pdf and it doesnt have any of the same cpu/etc? Anyone know which device this falls into?

Thanks!
[MTCB Android Head Units Q&A] wokro:
Many thanks for the upload. I waited for the KK.

Because I've not got my factory image from the seller I want to be sure about some questions before applying the update to KK:

My unit is a Klyde with Firmware: KLD 2.02 Android 4.2.2 / Scren resolution 800x480 for Honda Civic

1) Is the MCU.img from the 1024x600 download also suitable for the 800x480 units?

2) Has anyone already tried the new MCU.img ?

3) Does the CAN Bus SWC work OK after the update?

4) I've rooted my 4.2.2 device, I guess after flashing the new image the device is not rooted.

Has anone succeeded to root the 4.4 fw yet? If yes how can I do it?

Thank you very much in advance.
[MTCB Android Head Units Q&A] coudu:
I pre-rooted the update.img before flashing by injecting su binary, superuser apk and root daemon in the system.img.

As said, I need to test if everything works (did not have time to test everything related to google sync, aosp browser bookmarks sync may be missing so I'll add it in the image). When everything work I'll share.
[MTCB Android Head Units Q&A] ktibor69:
HU

Where can I find picture from GS or JY Android?

I have similar front picture HU, like klyde. But the back of the HU isn't similar.

Where can I find the setting of the dimming level?
[MTCB Android Head Units Q&A] Derell:
Update to KK

I have the GS with V2.02 and MCU2.08 and have a lot problems with my radiostation (always haft with all V?.?? and MCU) and the apk looks very ugly. After i updateted to KK , the Radiostation is still saved and don´t jump from station to another (HURRAY). The apk for Radio,Music and Video is very nice and the response is much faster. But not root.For me it´s not a big deal. Thx for sharing :) You´re guys are amazing :D;):good:
[MTCB Android Head Units Q&A] coudu:
aosp browser bookmarks sync is effectivly missing, I'll add it to the update image tonight before I share it.
[MTCB Android Head Units Q&A] typos1:
Anyone worked out what the "wheel3" and "rude" options in factory settings do yet ?

Its an AN21-U, try that thread.

1024x600 will work but bits of the sceen will be cut off

Yes, I ve posted about the new MCU having extra functions.

Yes.

Again, info is in the last few posts.

Post a link to your unit or a pic of it.
[MTCB Android Head Units Q&A] markastor:
Can You upload the modded update.img, please?
[MTCB Android Head Units Q&A] Stank0:
I've tried them all up to 2.02. 1.86 works the best so far but now I see GS 2.08 but I'm not sure what chipset is this GS for.

Nevermind. Haven't been here for a while.
[MTCB Android Head Units Q&A] devilsoft:
Hi typos,

can you please tell me where can I find the latest mcu.img for KGL4 (if newer than 2.03) ?

Now I have MCU v2.03, but it's not working properly, in the way that the dash screen is not displaying anything, unless I press the RESET button, but the display dissapears again after the unit is restarted.
[MTCB Android Head Units Q&A] typos1:
He said when it works he will upload it, in another post he said "tonight", have some patience.

---------- Post added at 12:23 PM ---------- Previous post was at 12:21 PM ----------

No sorry check this thread and the one on 4pda.ru, as far as I know 2.03 is the latest. KGL though, although there maybe a version 2.06, your ll have to check the threads as I said.

Edit: this quote mentions GS v2.06, GS versions appear to have the same hardware as the KGLs, so it may work

For those too impatient to wait, this may work, I HAVE NOT tried it though :

[MTCB Android Head Units Q&A] coudu:
Yes I'm at work now and don't have the files handy, I've just seen in my car this morning that bookmarks sync adapter was missing so i'll add it to the image tonight when I'll be back home and then share the modded update.img

Here is the site that i ordered my unit from

http://aosino.en.alibaba.com/produc..._CAMRY_2007_2011_radio_bluetooth_wifi_3G.html

My HU is for 09 Camry has firmware MTCB-JY v2.07, i think there is no pre-rooted flashabale img for it right now, unless you are willing to take a chance with KLD or KGL files.

All we have to do for the owners of MTCB-JY firmware is wait for a hack.

I havent rooted mine yet til there is an offline root method.
[MTCB Android Head Units Q&A] coudu:
I'm on KGL4 v2.03 mcu and it works well... might be a problem with your canbus decoder or canbus settings in factory settings.
[MTCB Android Head Units Q&A] devilsoft:
Maybe you're right with the canbus decoder, but in Factory Settings, I selected the correct CanBus. for my car (Opel), but I get the same behaviour. It works perfect, only when I reset the unit from the small hole near SD Card.
[MTCB Android Head Units Q&A] typos1:
No, for the latest update you can install the pre-rooted KLD KK that coudu will upload later as long as you do not touch your MCU and leave it as GS - this is not "taking a chance" it has been known for months that Android versions are compatible between all units

As it is v2.07 it is very likely that it will be very similar to the KLD MCU v2.08 with the extra MCU functions.

---------- Post added at 01:18 PM ---------- Previous post was at 01:15 PM ----------

Theres a chance this will be sorted with the latest MCU version - the KLD one has lots of extra CAN Bus settings, should only be a matter of time before we get the latest KGL MCU version.
[MTCB Android Head Units Q&A] devilsoft:
Thanks typos. I will wait for a MCU update then. Hope it will be sooner :)
[MTCB Android Head Units Q&A] coudu:
sorry, I can't help you more as i've got a vw, let's hope a new mcu solves your problem :fingers-crossed:

[MENTION=456516]typos1[/MENTION],

Ok, thanks for the confirmation, i can do Kitkat update from [MENTION=853627]coudu[/MENTION] file but no MCU update to the JY unit.
[MTCB Android Head Units Q&A] typos1:
Nothing stopping you from installing the Android KK update thoguh.
[MTCB Android Head Units Q&A] devilsoft:
I made a video recording with my unit CANBUS issue. he video can be seen at: hddp://youtu.be/AXSlXCBebW8 (replace dd with tt). I installed KDL KitKat 4.4 with KGL4 MCU 2.03, but it's the same story :(
[MTCB Android Head Units Q&A] nook'r:
yep, the screen looks really bad.

was the issue after you updated the Android image KK or the MCU image files?

you may need to try different combination of MCU files with 4.2.2 and 4.4 to figure out the best working set.

can you reinstall the original firmware that the unit came installed with?

if you have TwRP installed you can do a recovery from a working backup
[MTCB Android Head Units Q&A] devilsoft:
The unit screen looks great (maybe not in the video), but i'm talking about the top smaller screen, which displays fuel consumption.

After I reset the unit, the small screen display the information corretly, from KGL unit in the "Music" screen, where it displays "MUSIC: 00:15", but not displayng anything after I restart the unit.
[MTCB Android Head Units Q&A] lucky-jon:
Cortex A9 Dual core 1.0Ghz

on android-caraudio.com there are a few 1024x600 units. I was looking at the universal unit, SNAC-7005. (or SNAC-8009 - seems to have both references for same unit)

• 1024*600 Resolution, Capacitive touch screen

• Built-in high-capacity iNAND MEMORY 16 Gb

• Support ATHEROS ESP technical GPS module

• Support several navigation software(igo,route66,sygic,navitel,TOMTOM etc.),Support 3D Virtual navigation

• Support USB2.0 high / full/low-speed,Can be an external USB HUB(Added HUB will have up to 4 USB interface )

• Updates to this system can be available through the mobile Internet online upgrade or SD card

• Reserved enough interfaces for extensions

• 2 seconds fast start

• Support lossless music format WAV, APE, FLAC etc.

I think that having broader app compatibility is very important..... and with hi-res tablets and phones becoming so much more common, low screen res will soon be like old VGA PC screens..... way too restrictive. A slightly lower CPU speed is less of an issue for me than the prospect of not running apps at all.

Do any of these units pass video in through to video out on the RCA connections? I was thinking that I could plug a portable DVD player or other video source through the head unit if ever I really need to.
[MTCB Android Head Units Q&A] lukesan:
[MENTION=5855249]lucky-jon[/MENTION] to be honest if you think about it these models are all overpriced,

Lets see, $479 for that. I honestly don't need a dvd drive so good thing, but I think a dvd drive costs a lot of money. Electronics now are dirt cheap.

A tablet with those specs costs like $140 + an amp at about $50 + tuner $20
[MTCB Android Head Units Q&A] webdude12:
A side note on resolution. There are some 1280 x 720 screens starting to appear. LSQ Star seems to be the leader, but some others are following suit. Looks like I will be waiting a little longer now. :)
[MTCB Android Head Units Q&A] lucky-jon:
Yes, I totally agree. Without the drive, your talking a tablet, amp and tuner. Not $400+ worth.

Trouble is, if you actually are going to buy anything, you have to decide 'yes' at some point, and there will always be something better in the pipeline.

The DVD drive probably cost less than $20, but the integration costs were probably higher. It is hard to decide. Do I mind giving up the DVD? Only a little. I hate discs hanging around the car. Do I value higher res and more memory more than the DVD? Probably yes. Do I value the larger display? Yes. And I expect to pay less for something I value more? Hmmmm.

The support, build quality and reliability are actually what are most valuable, and truth is, with these units, you can't be sure about any of those things. For any of these spec's from mainstream brand names..... as far as I can see, the products aren't there yet, and those that come close are even more overpriced, and the support is still not guaranteed.
[MTCB Android Head Units Q&A] lukesan:
I'm having the same thoughts. At 1 time you have to decide.

I drive a vw jetta which is a company car and it has an RNS300 in it that costs like 6 times these units at the time ... and has navigation with arrows. So the only time I used that was .... never.

For now I have hacked the cd-changers output, since I am not going to pay $120 for a BT unit that emulates the cd changer, desoldered 2 wires at the connector, connected a BT receiver and leave 1 cd in the charger to let it play from cd ... but audio via that BT receiver from my Nexus 7.

So a couple of weeks ago I had this thing like ... I am fed up with all this .. lets use Velcro and my Nexus 7. Well I like it. It covers the RNS300 display but I can still use the volume button.

Radio, well TuneIn radio works perfectly and I use N7 audioplayer which I really really like.

1920x1080?

I was just viewing a home made dual din on youtube. The guy put in a 1080p tablet into a 7" dual din frame. Made me wonder why bother with 1024x600 or even 1280 res. Straight to 1080p seems logical. Android will scale as my SGS4 runs at that res now (in 5" size)

[MTCB Android Head Units Q&A] dark alex:
Hey, has anyone tried to connect a SPDIF Audio Dongle to the unit?
[MTCB Android Head Units Q&A] lucky-jon:
The funny thing to me is how desperate some of us have become to have the 'highest spec' (whatever that means). ;)

Car based gear has to suffer some very harsh environmental conditions. Extreme temperatures, humidity, UV exposure, dust, vibration....... (depending on your ride!) On top of that there are special ergonomic issues - ease of viewing / reading at distance, control by passengers, clarity of voice prompts, size of buttons/knobs......

Performance issues are different too.... needs to start quickly (all functions - GPS lock, nav software, radio / music, ODB2 ....) A vehicle install is likely to need to actually multi-task... play video, monitor vehicle stats, navigate, text-voice & voice command processing, web browsing, nav aids (POI's, route commentary) ..... and not overheat! Ideally, if you stop for gas / petrol, you don't want the whole lot to reset, but neither do you want to return after an overnight stop to find a dead battery. You need a decent amp (class D amps now really efficient / low heat dissipation) and radio / ?TV tuners... and still not too much heat.

I bought a tablet all ready to install it in a 2DIN cradle, but once I considered what I would have to do to get just a very basic system.... bypassing the lithium battery, re-working the charging system, deciding about suitable apps, dealing with other integration issues...... I decided that it was best to keep the tablet as it was and just make a dash mount for it. But then I am left without a car-based / integrated system. Do I mod the standard HU to give an audio in from the tablet, or spend $100+ on an external adapter.... or use a useless FM tuner aux-in device? What about video feeds for rear seats? What about video to the rear video and nav to the front screen?

The Parrott Android units are OK but so far behind on OS version and they attempt to hold you in their grip by making you use only their apps. If I am going to mess around with side loading / rooting etc, might as well start with a higher spec platform.

So here I am on this thread.... and I think that the best approach for me will be one of these units. Whatever the spec, $500 is my pain limit. Keep in mind what $500 gets you for a regular car entertainment system, and any manufacturer that invests in sorting out all the requirements above is going to want to protect their investment and not get ripped off. Now the Chinese get to feel a little of the pain that copyright and patent infringement causes!

The SNAC-7005 universal unit I was looking at is on a month lead time. :( They are offering a lower spec alternative with only 8gb (at a slightly lower price). Model CYCA-AD1240HD. But this one is showing as Android 4.1. Always a catch, right?

---------- Post added at 10:13 AM ---------- Previous post was at 10:01 AM ----------

I was thinking the same..... I want an audio out that can handle IR headphones. But then you need multiple channels / routing for audio! NAV through speakers, music / video through headphones..... and the ability to mix and match audio paths...
[MTCB Android Head Units Q&A] lukesan:
[MENTION=5855249]lucky-jon[/MENTION] you seem to think the same way as I am thinking.

Well harsh environments. My guess is that these radio's are affected the same way as a tablet. For sure I would put in 1 or 2 small ventilators that just let air flow thru the device.

My Nexus 7 2012, well I would take the back cover off so the airflow directly hits the circuitboard.

But for a tablet install I would go one which also receives Glonass ... which the N7 2013 does. Much faster and more precise gps.

I've been checking what's convenient with software as this resolution is already over the top. Hardware buttons are still the way to go if you can.

Just mount your tablet and try to hit a song you see on the list. No way you can do that in a safe way while driving.

GMD gesture control is cool as you can use multiple fingers to swipe over your screen and let it do certain things.

To be honest I would let the battery in the tablet. Reason is boot time ... well it is in standby all the time. Autosleeper works perfectly and I am sure you drive your car every week. It doesn't even have charge when the ignition is off.

I haven't found a good sensitive usb FM tuner so that is another thing, as the video out, well it's my device :D , so if the kid wants to watch a movie he can take his own tablet.

Maybe we should open up a different thread?
[MTCB Android Head Units Q&A] lucky-jon:
I too was drawn to the N7 / 13. Personally, I have moved away from the idea of using a tablet... except for giving to the kids to watch movies on!

I wonder if the screen mirroring is up to mirroring video for movies? That would be a simple way of distributing video around a vehicle.

I do think that there would be a lot of interest in a bundle of items that enabled integration of a high spec brand name tablet like the N7 into a vehicle installation. Even a 2 DIN chassis with decent amp, tuner, power regulator, RCA sockets, USB hub and fans pre-mounted ready to clip in your tablet would be a real time saver. The hours wasted trying to track down components that work is huge. That surely would be for a separate thread, but probably something going already as I have seen quite a lot of N7 & similar attempts at car installs.
[MTCB Android Head Units Q&A] sciallo:
On the tablet ideas... not only hardware-wise it's a pain to integrate, but there is software/firmware things intergrated in these units that make them much different from the tablet thing... a lot of it, most of it, could be replicated with some additional electronics and especially something like a IOIO and a lot of time finding/connecting the right stuff and even more time programming an app for it, and you're still going to miss some of the things these units offer, unless you really get deep into buiding your own and deal with audio and video switching etc. (think backup camera)

The Generic Android Head Unit/MCU Explained will give you a good idea of what I'm talking about and how these things are different from the whole tablet thing.

As one that was all about modding a tablet to mount on my dash I am now completely convinced these are well worth the $$ they cost, actually a really good deal... no unit with built in navigation and a touchscreen costs less than these locally.
[MTCB Android Head Units Q&A] webdude12:
I have looked at doing an Nexus 7 many, many times. But there are some things that stop me every single time. With all the parts and the Nexus 7 new from Amazon, I will spend around $580. But its not so much the money as the things I loose.

No real FM Tuner, have to rely on an internet connection to get music. I do some traveling, and I can tell you, a traditional radio tuner will pick up for approx 100 miles from the tower. The Tuner in the tablets through the Bluetooth chipset do good to get 20 miles away.

No real way for a standard aux in. One of my best friends is an artist in the music industry and likes to play me new stuff he has either written, recorded, or on some occasions produced. We often do this while driving down the road to get eat, goto the movies, etc. He does not trust Bluetooth at all, even with me, so he will only play me stuff through his headphone jack. He knows I would never leak anything he played for me, but then again, he doesnt give his own mother copies of most of his unreleased stuff.

Lastly, No CD / DVD player. While 99% of my music is on Google Music, there is some stuff that I get from my connections that I wait to load onto there. i.e. pre-release CDs from other artists, etc. But also Google Music is heavily dependent on a internet connection. Yes it caches what I listened to lately, but sometimes, I want to be able to throw a CD in and listen, without having to tether the device.
[MTCB Android Head Units Q&A] lucky-jon:
That's why I am here!

Just heard back from android-caraudio.com. The universal 1024x600 snac-7005 is only available with 4gb inand at the moment (!). One month for 16Gb. They suggested the older unit, still 1024 x 600. ref: CYCA-AD1240HD. Any one looked at that one already? Spec looks very similar to the snac series. Still only 8gb version available.

[MTCB Android Head Units Q&A] dark alex:
Well the reason why I'm asking about SPDIF is not that I want to have another audio out but I have the "beep-issue" on preamp outputs and I have a DSP which can handle SPDIF.

I do not want to use High-Level-Inputs when I can get it running "cleanly".

There is nothing better than digital trasmission (SPDIF)... No chance to get any nois into it... except the "last meter" from DSP to Amplifier.
