Hey, wondering if you could extract the stock Vehicle Information app into a backup .apk file to share with MTCD rk3188 users to test cross compatibility.
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
I did extract just have to post
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:
Anyone know how to root...yet
[MTCD  Android Head Units Q&A] dongali:
Try your luck with kingoroot or king root. They work for majority of devices.

About the extracted app, maybe you could have the new thread include all the stock apps including the vehicle information app.

Here you go
[MTCD  Android Head Units Q&A] RWerksman:
Reading a bit about the Teclast thread, it looks like it's rootable via Kingroot. (or perhaps Kingo Root) It might be the same procedure as any MTCD to root.

I just rooted my MTCD Joying using this afternoon using Kingoroot.

*#hct#root# in the password to get into factory settings.

Install Kingoroot.

Click root.

Change DPI (in my case, that was the first thing! :))

how did the vehicle apk work out for you

Hmm I just ran Antutu with my Galaxy S4 and the result was 43000 points. I'm running latest CM13 on my phone. With 24000 I fear there could still be some slugginesh.

Could you kc2koj@hotmail.com post a video of changing between apps and general responsiveness of the unit?
[MTCD  Android Head Units Q&A] ikerg:
Don't expect high rates on Antutu.

Atom x3 is a basic processor .

But it is well prepared for connectivity.

Rk3188 is an old processor

C3230RK is quite new processor...but u don't think to have good support as the joint venture between rockchip and Intel was broken...and sofia project died.

So we will never see (again) source code for custom ROM.

At least I think we could have marshmallow as teclast x70r has (I read it somewhere)

Anyway .... it is a headunit and don't expect to behave aa powerful tablet. It is limited to the things to do while driving.

Unfortunately, it seems the apk isn't compatible with our rk3188 MTCD. Install fails even after I uninstall the original vehicle information app. I also tried forcibly installing it by copying your apk to the app folder and changing to proper permissions. The app will show up as installed but crashes immediately on open with an error message.

You will have to wait for root I guess to be able to adjust volumes
[MTCD  Android Head Units Q&A] xlinkx:
I got this factory settings code *#hct#root# from the joying forum which enables adb-root and it actually works with our HU but kingoroot, kingroot and towel root doesn't work. There's another option to use a pc version of kingo root but I don't have a USB Male to Male cable to test it. I also found out that "USB drivers All Devices" from play store opens up developer options and USB connections. If anyone have this cable please give it a try.
[MTCD  Android Head Units Q&A] standov:
But can you confirm the same issue? Or I doing something wrong?)
[MTCD  Android Head Units Q&A] leonkernan:
Not surprising, ones an ARM processor, the other x86. Most apps would be compiled for both but some hardware specific ones might only be for one platform or the other.

For example, if they've used JNI code and only compiled for x86 and not ARM then it won't run on an ARM unit.

Which navigation app are you using when you're having the issue and do you feel the update made any improvements with anything
[MTCD  Android Head Units Q&A] standov:
looks like any nav app. Confirmed with google, yandex, here.

If I setup nav app as default (called by nav button) - then when nav app should say something- I hear that FM sound muted but not hear anything from nav. For nav apps that not set as default - I just hear 100% of time FM sound and nav apps just silent.

Changes of GPS sound modes in android settings seams not change anything. Voice options in factory setting does not change anything too (and after reboot even).

My unit alibaba seller say about:

"Hi Stanislav.you can not the GPS sound when you listen to radio,music from USB. Best Regards" ))) But I think he is wrong and just does not want to fix
[MTCD  Android Head Units Q&A] kc2koj@hotmail.com:

You mean system volume control in top status bar? It's not muted and set total volume - I hear FM well ) I does not have any other controls. Google navigator "mute checkbox" is not checked

Exactly why I am not buying it until it is fully vetted by others. The confusion regarding marshmallow updates to these brand new units is also a reason to wait. If these 5.1.1 units won't be upgradeable to MM there is no sense in buying them at all.
[MTCD  Android Head Units Q&A] CadillacMike:
it is weird. They are clearly new units, there are like 3 of them. They have 1Gb of RAM, but they do mention Sirius compatibility, which I think is new:

Sirius support

. Essentially given basic Sirius functionality to the head unit if you install SiriusXM SXV300v1

. Channel and program info displayed via RDS text, adequate for your needs.

. Adjust the radio FM/AM sensitivity to get better radio reception

. Support to rename the radio stations

I owned the rk3188 universal like this...

Due to display failure I am returning back to seller.

For 30usd I am.planning to upgrade to 2Gb ram model with the same fascia...so only 1slot is available.

On the rk3188 this slot was for gps sdcard but the guy on HotAudio told me that this slot on the new 2gb Intel is for 3g sim card....so I lose the sdcard.

I should use the USB extensions to add additional storage for maps if I don't want to leave them on nand

Hi everyone,

this device looks really well done !!

I would like to buy it but I would have some questions, I hope someone can answer:

1) The internal Bluetooth recognizes all connected devices (such as OBD, TPMS, Bluetooth GPS etc.) together with the smatphone ??

2) When several devices are connected to Bluetooth, i can always make and receive calls via Bluetooth ??

3) I can use "OK Google" function ?

4) If I connect an external microphone and say OK Google the radio recognizes it ??? i can activate OK Google from any screen ??

5) When I turn off the car, the radio switches off completely or remains hibernated ??

6) If there's hibernation, i can choose to keep the car radio always hibernated without end ??

7) If there's hibernation, when I turn on the car radio from hibernation it comes on immediately or stays with black screen until you touch the screen ??

7) After a restart of the car radio the steering wheel controls are all immediately available or there is a waiting time ??

8) Can I make calls from my Google Contacts or do I use the phone contact list from app ??

9) I can call Google contacts using OK Google ??

10) When I make a phone call the other person hear me well when using an external microphone or my voice is low ????

11) Someone tried to make the root using KingoRoot ??

Thanks for the courtesy to respond

[MTCD  Android Head Units Q&A] j2mcentire:
Not great, bootloop after update... But I now know how to get into recovery:

1. Turn completely off (or press reset)

2. Turn on and hold back button

3. In 8-10 seconds the button lights will flash, continue holding back button for another 3 seconds

4. Release back button, then press and release once again.

It takes a couple tries to get the timing right, but once I was able to get in I did a factory reset and got it to boot again.

For me it is very important this fact Ok Google and the Google address book, I would buy the device but would like to be sure that these things work.

You may re-verify that they work ???

This is the device link I want to buy:

https://it.aliexpress.com/item/3G-4...iversal-Car-Radio-Double-Car/32719447273.html

So, if I am understanding this correctly, the Intel based 5.1.1 units that Bonroad is selling right now will NOT be upgradeable to Android 6 Marshmallow, but the MM units are coming out at the end of the month? If that is the case, there is no reason to order one now.
