If i am wrong ... some joying devices, even having intel...they have different mcu and different ROm....so the root procedure that worked for mtcd Intel units failed for them.

As you have mtcd Intel based ... I think you could root with the procedure detailed by kc2koj ... perhaps kc2koj could give you more details.

I have not received yet my unit...I think it will be different than joying and similar than your and than kc2koj's

[MTCD  Android Head Units Q&A] doitright:
That is something that you would DEFINITELY NOT want. Double bluetooth causes all kinds of problems and solves nothing. The reason why cheap head units USED to ship with double bluetooth was because they weren't smart enough to add bluetooth HFP-client profile to the Android bluetooth stack, which would allow Android/Linux to be the gatekeeper of all of the bluetooth connections. Instead, they hacked on a second AUDIO ONLY bluetooth device to the MCU.

The next iteration of this MTCB-MTCD/rockchip which have the bluetooth on the MCU board, and they have a slightly expanded functionality. Essentially, they fake the bluetooth connection for ODB dongles through the SoC <--> MCU interface. Its UGLY AS HELL, but better than nothing. Oh wait, no it isn't, its just ugly as hell.

Google pulled in bluetooth HFP-client profile from QUALCOMM CAF into Android 5.0 or 5.1, which means that Android is able to deal with calls over a REAL bluetooth device connected to the SoC now. This is what we are starting to see with the INTEL units. Well, at least some of them, since it isn't quite clear what is going on with joying units just yet.

The parts you have circled look like they may be power filtering circuits. The components on these things do NOT run on the variable ~14V spikey power that comes from a car electric system, the voltage has to be reduced and CLEANED. I don't think that your video glitch is related to that particular sloppy soldering job.
[MTCD  Android Head Units Q&A] sterod:
I highly disagree with your opinion that dual Bluetooth is bad. I have a head unit from a manufacturer named newsmy which has dual Bluetooth and I had removed it from my car and replaced it with joying mtcd unit that ran Rockchip. That was a disaster as absolutely nothing other than the phone and OBD2 dongle worked. I have since put the newsmy unit back in my car as with the Dual Bluetooth the one that is visible to Android connects to my radar detector flawlessly. From what I have read the Intel based units are still too premature to see if they will be able to handle simultaneously connecting to my radar as well as my phone with a single adapter. I will wait until the dust settles and they get this working perfectly before I ever consider removing my working newsmy unit again.
[MTCD  Android Head Units Q&A] marchnz:
Yes I have an understanding of chinese manufacturer claims. I too was sceptical and resquested further information which resulted in users and reseller providing further information. I have reviewed supplied photos and can clearly see change moving functions embedded into listed SOC such as WIFI, further strengthening credibility. From your review, apart from heatsink and images, what do you see that could prove as fake or otherwise credible?

Ive reviewed the images including 3rd party app displaying intel cpu and 2gb RAM, so what do you propose to prove head unit specifications are as advertised?
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
read the page theres a 1gb ram /2gb ram / and coming soon 2gb ram with 32 gig of storage...i have no reason to bs anyone ..you have to choose which one you want..... every app i run for android hardware reports an intel cpu ..including the os
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
why would they go through all the trouble to fake when there not asking for a premium price or advertising as an intel cpu......it seem like to fake and not tell anyone / its an intel or/ sell for a higher price . wouldn't make any sense...

Most likely it is a Rockchip Sofia which is their newest smartphone chip. It is the only Rockchip product with a MALI 450 GPU on board as shown in the screenshots. It is not an "intel chip", it is an Atom compatible chip. Very much like the Broadcom processors used on the Raspberry Pi's.

http://www.rock-chips.com/a/en/products/SOFIA_Series/2015/1125/734.html

It will probably not be all that huge a performance improvement, since it is designed for low end smartphones and tablets, but it should at least be able to play Netflix just fine now with the improved GPU capabilities.

i was thinking it was this cpu

Intel® Atom™ x3-C3230RK

anyway if its x86 we should be able to run some other os s maybe even dual boot thats what im thinking...

i will post the bench marks in a bit maybe that can tell us all something ...
[MTCD  Android Head Units Q&A] nixfu:
Just like the other Atom system-on-chips such as the one used by RaspberryPi's it ALL comes down to driver support from the manufacturer. Without them providing driver support for open source Linux then things like the on board graphics display, built-in network connectivity, on-board wifi, etc will not work on Linux.

BTW, I would like to see some wider shots of the board from a higher view showing more of the whole thing in a single shot you have them.
[MTCD  Android Head Units Q&A] dongali:
Seems the chip is made by Rockchip but it's rebranded by Intel.

Compare the two:

Rockchip ATOM X3-C3230RK

I wonder if they are using the ones with built-in GSM/3G/LTE capability, or the Wifi-Only versions.
[MTCD  Android Head Units Q&A] dongali:
According to the website I linked, the Rockchip/Intel Atom X3-C3230RK seems to support the following basebands:

• WCDMA, HSPA+21/5.8Mbps

• EDGE/GPRS/GSM

Not sure if it's usable through the stock rom though.

[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
If you look at my pictures of the Intel SoC you can see it has a hook up for a 3g/4G antenna and your right doesn't look hooked up but there is a antenna jack on the back that I'm not quite sure what it's for
[MTCD  Android Head Units Q&A] marchnz:
Or not.

Why start with view point that it is fake it has not been proven so and I dont see how your argument establishes fact.

I too have outlined that there is a hardware difference and that the wifi/bt has moved onto the SOC (which is part of intel SoFIA as is 3g) or are you saying that too is fake?

Also, no one here is being disrespectful to you, so please do the same.
[MTCD  Android Head Units Q&A] nixfu:
WELL, if you know more about the design, it is possible.

You have to remember these systems have basically TWO parts.

The MCU, which is a low level embedded microcomputer(most of these have the popular STM32 microcontroller on them, I a few of those myself on prototyping boards) that controls lots of the low level stuff like the screen input switching, etc...and the ANDROID part which is a general purpose processor running Android Linux. The android system justs talks to the mcu and other sub-components, like the external bluetooth board they were using, via system busses like i2c or SPI so you could easily swap out a different processor board and keep the same low level MCU components.

[MTCD  Android Head Units Q&A] schriss:
So is it 1 GB or 2GB RAM? I don't mean some "Info" or benchmark apps which will show whatever specs the manufacturer enters (it could even report 8GB RAM), I mean how much RAM the system actually sees and uses?
[MTCD  Android Head Units Q&A] DanB0y:
Stop being rude for nothing, it is not a fake it is real, some people on russians forums have the same type of head unit.

---------- Post added at 05:46 PM ---------- Previous post was at 05:40 PM ----------

On the benchmark you see that it uses 1138.3mb / 1947.0mb

While it is absolutely possible that you can make the system "lie" about the total onboard memory, I highly doubt that you can make the system lie about

the memory actually in use

While I have no previous experience with another HU, My Joying JY-UL135N2 allows me to connect to my Nexus 6 and Escort Passport Max2 simultaneously. The Max2 will NOT connect in the bluetooth settings menu, but it connects through the EscortLive app fine. However, no BT OBDII adapters have connected via bluetooth through Android directly OR apps. I have 4 different adapters tested so far. Only the WIFI adapter connects with any application.

I fully agree with sterod, I also have a Newmsy with a double bluetooth and worked perfectly.

With this unit you are able to use the OK Google commands to make calls on the phone.

You create a BroadcastReceiver that catches the BOOT_COMPLETED Intent, and then creates a new Intent to launch the target application.
[MTCD  Android Head Units Q&A] avenant:
I don't think they made a mistake, if you buy this unit now, you also get the same one, they just have their Aliexpress specs wrong, that's why the specs show as processor speed 1.2 Ghz, instead of the 1.6Ghz of the rockchip/arm quadcore.

Realize that with Nova Launcher Prime you can design your own UI. So, if you don't like the way I did mine, you can create your own. Here's a list of the apps I used:

ProjectM Pro (for the live wallpaper that dances to whatever audio is playing).

Beautiful Widgets (literally thousands of options for time & weather with programmable sections of calling up other apps)

APW Widgets (calendar & people)

Ulysses Speedometer for overlays of speed, direction & altimeter

Poweramp Music app (I like the UI better than jetAudio and it sounds the same)

Speedtest.net for Internet testing

WeatherBug Elite for detailed weather & radar

Google Calendar

Hangouts for SMS & MMS

Google Voice number for Inbound VOIP Calling

Hangouts Dialer for calling

Docs to Go for accessing all document types (I use a personally created spreadsheet to track mileage and auto expenses)

I installed Kodi, but it runs very slow on this device.

With the exception of Kodi, the HU operates smoothly and I haven't experienced any crashes so far.

I connect to BT with my phone for calls & contacts (not music).

I connect to WiFi via tether from my phone

I play Music with Poweramp from the 128gb sdcard connected to USB0.

I use Google Maps for Navigation.

I have a Data Only Simm in my phone, so all in bound & outbound calls are VoIP via Hangouts & Google Voice number.

I cannot get the ODBII BT device to connect & the HU won't connect to my VZW USB dongle in either 3g or 4g.

screen size is the same: 1024x600 and there are 2 versions for landscape and portrait, so the landscape one, TWRP is controllable through touch screen, doesn't need special buttons to navigate like the stock recovery, so that only leaves the partition table...

How do you get Nova (I have Prime) to place the dock at the bottom of the screen?

[MTCD  Android Head Units Q&A] wanb1i:
I've been using Nova so long I guess I'm used to it being on the right in landscape, never really thought about it.

Apparently, you can't. I tried the advanced section using an overlay, but it still stays on the right side. Frankly, I'd prefer to have the left side (closer to the driver), I'm a beta user, so I'll request that we have the ability to move the dock. If you're also a Beta tester, please ask as well. Squeaky Wheel gets the grease!

[MTCD  Android Head Units Q&A] doitright:
When a new media device is connected to Android, the media service goes through it and scans it for media (basically catalogs all the files into a database). This can take a significant amount of time, even on a flash disk with no head seek or rotational latency to worry about.

With an excessive number of files to catalog on an obsolete spinning magnet over USB2 (which is *SLOW*), it is bound to take a very long time to complete.

You also need to consider the disk layout itself. For instance, is the partition table a compatible type of table? Is the partition type flag correct for the partition format? Is the partition format something that Android (in particular, CHINESE Android -- so probably you can only expect vfat to work, which probably can't deal with that big of partitions to begin with) can deal with?
[MTCD  Android Head Units Q&A] avenant:
Ok so that's whats happening, I always saw in the status bar a message about android scanning the SD card (even tough it's a USB HDD), but this took really long, so I cancelled it, so basicly I have to wait for android to finish this, even if it takes 10 hours, so what you are saying is once android has cataloged all the files into a database, the next time when i connect it, it won't start this long scan? Or will this scan happen on every reboot?
[MTCD  Android Head Units Q&A] doitright:
It *should* (no promise here, since these head units are different than most phones, and USB disks are a bit different than sdcards) remember what it scanned upon reboot, HOWEVER, there are certain events that will trigger full or partial rebuilds of the database. If everything is "correct", the old database should continue to be used while the new one is being generated.
