mine is also 1024x600. So we have identical hardware and software. nice.

can you please post a procedure for applying king root to the device? nobody in this thread has explained it.

I appreciate the op and his desire to keep track of these units, but I think it's not being maintained very well at the moment. Quite a bit of info in the first post is inaccurate. Now that more users are coming forward as owners, we really need to be pro-active with posting information, problems, tips & tricks, etc. so we can get more owners & eventually dev support.

From my experience w/ a Klyde/MTCB unit the AN-21U is a better unit that deserves to have more support.
[Android Head-Units] imableeblob:
I have updated the first post to the best of my ability. I do have work and it is holiday season. If you would like something added/fixed just request it. No need to complain about it. :)

Now after seeing your pictures I have a few questions. Did you add the OBD as a extension to your purchase, if so how much did they charge and did they give you the app to connect to it. Because if they did that would be very beneficial in many of these hybrid and older AN-21U units. That app is the only way to connect to a OBD device through the unit. Also, your version is updated from some of our units here. My unit version is 4.4.4 and I noticed you have a nicer GUI and that your version is 4.5.2. If possible can you get those update files and I can experiment with the update feature. However not sure if I will be able to change the resoultion. Does anyone have a 800x400 4.5.2 Version?
[Android Head-Units] Hisma:
thanks man. I see you updated the first post with more useful info. Appreciate it! I guess I'm just eager to do more with my unit but the lack of information is frustrating. I think we'll just need to give some time for more people to obtain these.

OBDII was an extra purchase but they only charged $6 for it. Yes, the app came pre-installed with the unit.

I am not sure how to extract the update files. Any directory I should check? I can install root explorer and look, but I wouldn't know what to look for.

edit: looks like you put a link to kingroot. Thanks!
[Android Head-Units] mxv68:
kingroot to install and follow the steps, I had to do twice.

the first did not work, restart the device and run,

It took 2 or 3 minutes only.

then install rootexplorer and could go to the root.

take a post as more upload the original rom
[Android Head-Units] mxv68:
someone modified radio or music player?
[Android Head-Units] kenfly:
Kingroot seems to be permanent. I factory reset my unit multiple times and still had root afterwards.

Anyone able to DL the system zip from my post earlier to see if it's the correct one for our Quad core units?

Maybe someone will be able to turn it into a custom ROM.

root the machine,

use TB to uninstall it and download the latest play store apk online and install it
[Android Head-Units] BiliTheAxe:
I also own the unit on the top left of the first page.

So far I have rooted mine and installed a 12 volt USB hub with a 240 gb Intel SSD drive for music and video file storage.

Installed Torque pro. I am using an OBD2 adapter from ebay that I already owned, and it works fine.

I had to force it to allow me to install Poweramp, as the play store said it was not compatible with the system. (I just found the APK file online for poweramp, downloaded it and did a manual install. It works fine.)

In settings, DO NOT screw with the resolution!!!. It took me a week to get the resolution set correctly again so that I could use the unit.

I own a Dodge, and it did not have the boot logo for Dodges , so I had to add one to the boot logo folder. HUGE pain in the butt to get the file in there.
[Android Head-Units] imableeblob:
- Thanks for the update on the OBD2! Mine from eBay was broken so I've been fighting Chinese for the last week.

- I did the same thing!!! Took me so long to get it back by guessing where to click.

Hello, modify some applications.

bluetooth, music, radio and launcher.

put the MTCB, only I got to work launcher.

---------- Post added at 02:06 AM ---------- Previous post was at 01:58 AM ----------

modified with rootexplorer.

Then restart the device
[Android Head-Units] deekgozzinyea:
I've already rooted it with Kingroot. So, my follow-up question is what is TB. Pardon my ignorance please, this is the first android head unit I've dealt with and I'm totally clueless lol. In case no one else has posted it, the procedure to root these head units with kingroot is simply install the 4.05 (or 4.5) version, run it and hit the root button. Make sure you don't have any running apps or it will fail. As long as nothing is running though, it will achieve root in about 60 seconds at most. Also, does anyone have the updated MCU files and image/firmware for these units?

---------- Post added at 05:41 AM ---------- Previous post was at 05:24 AM ----------

I played with the resolution also lol. took me two days of testing to figure out how far offset touches were and get it back to 800x600:D
[Android Head-Units] BiliTheAxe:
from this we have learned that a warning about this is needed at the top of the first post in large bold letters.

Warning, do not mess with resolution settings.

I don't feel so bad about it anymore.
[Android Head-Units] Hisma:
just want to add that I fixed the issue with my steering wheel controls. I just wasn't mapping them correctly. They appear to be sticking now.
[Android Head-Units] fyid:
i haven't seen anything in this thread yet, other than a unit that said it was android 5 but was really still 4....
[Android Head-Units] delarium:
Thanks for reply.

Seen alot of devices on Ebay, Ali and so on with Android 5.1.1. Not sure if its different devices though.

How fast does your devices boot from initial ignition turn on? My unit takes more than 50 seconds before getting into GUI. How to speed this up?
[Android Head-Units] fyid:
mine takes 30 seconds... i removed the SD card because it was causing hangs, maybe an SD card or USB stick is slowing yours down?

[Android Head-Units] JonGillibrand:
Hi guys,

Does anyone have a guide to installing XposedMTC framework on this unit? I tried installing the apk from the framework thread for 5.1.1 but even after a restart I get the error that the framework is not installed. I tried a couple of times and always comes back the same. From what I've read XposedMTC is exactly what I need to get the HU working exactly as I want it!
[Android Head-Units] Cid6.7:
Is there a trick to these to get the bluetooth to find your phone & OBD connector..?
[Android Head-Units] wigglitz:

Purchasing IQ Navi/RedMod seemed to add a lot and fix a lot of features I was looking for.
[Android Head-Units] weirdcat:
Hello, I believe I'm at the right place with this HU:

QuadCore-R16 1.6G

Android 4.4.4

MCU 5.3.8-11-952-453101-160624

System 4.5.10_20160701

I'm having one problem with the unit. When I turn the display off and change the volume (using either the knob or the steering wheel buttons), the display turns back on. This is quite annoying especially during night time driving. Do you guys have the same issue? Did I miss some settings option that disables this behavior?
[Android Head-Units] JonGillibrand:
Mines called OBDII so I dont think its that. I dont see the point in installing 5.1.1 myself. The front end is (even more) fugly than before and I dont see any other benefits over when the unit was 4.4.4. The passerger side of the dual-zone air con still always says LO, and the same range of pish apps are installed. If you have somewhere to host the files I can send them to you if you really want?
[Android Head-Units] ADB100:
Is it definitely 5.1.1? There have been reports of some units being delivered with the about screen saying 5.1.1, however its still 4.4.2 and the OS has been modified to say 5.1.1. If you go to 'Settings, About' and the press rapidly on the 'Android' version you should get the demo screen and if its still KitKat you will know...

I can probably give you somewhere to upload it if it is genuinely 5.1.1

Andy
[Android Head-Units] JonGillibrand:
On double tapping the android version I get the following:

A large letter K that spins around, on tapping that

An android splash screen with the logo in the form of the KitKat logo buy with the version no shown as 5.1.1 at bottom. Is this the fake 5.1.1 update?

I already uploaded the files to the google drive of Wigglitz, I don't know if he is willing to share?
[Android Head-Units] Cid6.7:
Pretty sure thats the rebranded kitkat...

How would one go about getting legit lolipop ?

Does someone need a unit to do the mods like Malaysk ?
[Android Head-Units] JonGillibrand:
Does that mean that if Im still on KitKat I can still flash the iqnavi firmware? Does this fix problems with bluetooth OBD dongles?

---------- Post added at 06:15 PM ---------- Previous post was at 06:14 PM ----------

and on the iqnavi, can I change the default music player app so it responds to the hardware button and starts playing from where it left off on startup?
[Android Head-Units] ADB100:
The big spinning K means its KitKat. I doubt the IQNavi software will fix any of your issues though, but by all means try it and see.

I have the same issue with my OBDII adapter - it advertises itself as OBDII but I can't pair with it. The Bluetooth hardware/app seems to only pair with phones.

You can't see a Bluetooth option in the Android settings because the Bluetooth module isn't part of the Android hardware - this is MCU. The Bluetooth app 'talks' to this external hardware so Android natively has no Bluetooth support.

Its all a bit of a bodge getting the various hardware components integrated with the Android hardware (which is just one of the inputs to the MCU). There is an explanation somewhere on here that details how the various components interact and how its the MCU that is the back-end 'glue'.

I have been playing around with mine for ages as it just doesn't quite work right (phone volume, BT volume/MIC, SatNav audio etc etc) and I keep putting the OEM head unit back in place as this just integrates so much better. I am tempted by one of the MTCD Android 5.1.1 units, however I suspect the integration and Bluetooth issues with be the same.

Andy

Andy
[Android Head-Units] JonGillibrand:
I guess the USB controller is via MCU as well? Has anyone had any luck using a USB Bluetooth adapter? I'd go with a USB obd cable but the cable in the footwell to the OBD port would annoy me.

What's really annoying is that the D90-810 says it has support for torque on the Audiosources Australian website.

Has anyone retrofitted the B6 Bluetooth controller to get around this OBD problem?
[Android Head-Units] Cid6.7:
I have a vid that shows how to pair the OBD bluetooth reader & "some" instructions from the company I bought mine from..

https://www.mediafire.com/?mc7rm07jcoztu6a

please check the video

if not please change the bluetooth code 0000 and connect again
[Android Head-Units] ADB100:
I tried a BT USB adapter but had no luck. I did have some luck with the OBDII USB cable that I use with my Windows PC with VCDS (Audi), however the connector is on the drivers side and is just in the way.

I have seen the video before, however I can't get it to work - spent ages on it...

Andy
[Android Head-Units] JonGillibrand:
I installed the IQ Navi firmware last night and the interface is MUCH better looking than any of the previous I've had from audisources!

I still havent had any luck with pairing the ELM327 adapter though. I watched the video you sent and I can almost make out that he gets a "pairing successful" message, however mine never shows this. I know that the passcode is 1234 for my dongle as I tested pairing it with a laptop and running the PC based software that comes with it.

Pulling my hair out with this now. Having torque was one of the main things that made me go for this unit!
[Android Head-Units] JonGillibrand:
Thinking outside of the box, and being at my wits end already with not being able to pair this OBD adapter, has anyone ever seen a different version of the Bluetooth app that works with MCU? maybe there exists a version from a different build that the apk could be extracted from? I've flashed this unit 4 times now and always have the same v1.0.0 of the same crappy app!

There has got to be a fix for this. Audiosources sell an OBD adapter, it's an ELM327 same as what I bought off eBay for 10% of the price.

This guy had it working on a d90-810 the same as mine, but that firmware version I haven't been able to get my hands on

[Android Head-Units] wigglitz:
I'm just throwing whatever else I can think out there. Since switching to IQ Navi, have you used the full data wipe file then install Navi again? That changed a lot for me when I actually did it in that order. I dunno :/
[Android Head-Units] JonGillibrand:
How is the full data wipe file carried out? I did do a factory reset but the supersu still remained after so I didn't manage to wipe everything. What did a full wipe cure for you?
[Android Head-Units] wigglitz:
The entire time from when I installed IQ Navi, I thought the interface was what it was after. After using the data wipe, I found a few new menu options and apps. I can't remember specifically what ones they were, but they were helpful. It's just like you would to install the main firmware, but instead you use the long hash sytle/form file that's small and I think starts with a "b". I had no luck with the 5.1.1 firmware when I tried. Was able to root it with KingRoot and then switch to SuperSU, but I still had random instability.

---------- Post added at 07:38 PM ---------- Previous post was at 07:35 PM ----------

Quick question:

On my MTCB unit I was able to use the "F-Cam" app to switch between my front and reverse camera without having to engage reverse. I noticed IQ Navi has 2 front cam apps and a dvr app, but I don't seem to be able to accomplish this with any of those. Has anyone an idea that would allow me to view my reverse camera when wanted using an app?
[Android Head-Units] Cid6.7:
My unit has 4.4.2 build 4.5.9 on it at present is this the latest ?

Could someone please post the links to the newest upgrade & the IQ Navi firmware..

[Android Head-Units] ADB100:
Sounds like the resolution is wrong. When you touch the screen does it register you have touched it somewhere else? In the Extra Settings menu there is an option for screen resolution. I did this and through trial and error and trying to judge where things should be on the screen I managed to recover it. I have a 800x480 screen and it somehow reset itself to 1024x600 after an update.

Andy
[Android Head-Units] 93d16z6:

There is no setting for resolution. I did get the screen position thing figured out. But there is nothing to change it back. Did some updates have it and some didnt? Thank you for your help so far!!!!!

Greetings, I have one of these units not pictured but similar, I was able to root and put IQ nav on it. I had issues with the odb2 reader but after changing the passcode to 0000 like mentioned here it works. I did find out that;'s it cheap China crap and does not work entirely. It reads real time info fine like speed, rpm, sensors and what not but failed to retrieve a code from the computer after my check engine light went on. It did not read any code but when I went to Autozone their reader was able to read the code. So its going to be trash as soon as I get a better quality one. My only issue with the entire unit is I installed google maps and it works fine until I hit the navigate button in directions. It starts to zoom in to the map but then fails and does nothing. After pushing the button again it does the same. Anyone have any ideas on a fix? I tired uninstalling it and reinstalling it, and the problem was there before I flashed IQnav. I'd like to get google maps working as I have a Mexico road trip planned and would like the superior google maps and database instead of the already installed nav app.
[Android Head-Units] Cid6.7:
Try installing the offline maps for it.

Mine now gives me a problem with the Bluetooth whereby I can connect to it from my iphone but it doesn't register on the head unit (connected icon, any Bluetooth functionality) and on each startup when I go into the Bluetooth all the all the settings (name, pin, auto connect, auto answer) aren't defined. Setting them doesn't make any difference. The device always appears under its old name when I try to pair again from my phone. It's like the link between MCU and android isn't working.

Has anyone ever had any success with another Bluetooth app for managing connections? Is there an updated version of this crappy app that I can install? When I check from the apps menu it shows as 1.0.0 whichever firmware I install

Anyone know if it might be an easy change of a configuration file to have the rear view camera come on when a turn signal is engaged? Or set to a completely different camera? I can think of a possible way to wire another camera to do what I'm looking for. I just figured it couldn't hurt to ask.
[Android Head-Units] Cid6.7:
That would be pretty cool having a camera on each side of the car to see if anyone is in the lane next to you.. But I dont think wiring it into the turn signal would work as your camera would flash each time the light would blink.. You'd have to wire it before the turn signal relay I'd think..
[Android Head-Units] wigglitz:
Yeah, I already have it figured out on how to get around the relay signal. I just don't feel like doing the work.
