[MTCB Android Head Units Q&A] MMouse:
Hi Guys,

Its been a couple of days since i posted. So im just bringing my latest developments.

For start i own the KGS8401 VW

Findings

-Entering an ADB command will reboot my unit or at least the UI and all the apps togther with it. (its reproduceable)

---WIFI disables and SSH server stops

-Camera.apk is not installed, this is a system app and can be installed. You have to mount /system in write mode

---This fixes other camera utilities other then, the shipped DVR app

---Video recording only works with apps that dont use the default video recorder api, like CaroO (when set to continous recording)

While tweaking and tuning something broke the system sounds together with IGO sound.

All other build in and 3rd party apps did not have issues.

I ended up reflashing the thing to the new firmware (dropbox link is dead btw)

I can confirm that splicing, or simply connecting the orange wire (the illumination ISO wire) to a 12+ signal will continously poweron the button lights.

I have purchased a delay relais 110sec max (solder kit) that allows the harddrive to powerdown after the system has shutdown.

(ill post the details once its live)

The startech.com Industrial USB hub is very solid, operating voltage 7-15

Realy heavy duty material, and not to expensive (50 euro 4 ports 80 euro 7 ports)

Only 2 more days to go before i get my new car...

I cant wait to strip it down, lol

Thanks everyone
[MTCB Android Head Units Q&A] brownstein72:
It seems to be working ok for now but I am weary that the wire will break, the piece I added is on is far too heavy for the existing piece to support it. If I were to take the unit apart and wire a whole new antenna wire to it (coax) would that work? Right now it has the shield separated from the core and each part is soldered to two connections on the board and then the wire just hangs there. Would I have to do the same thing with the coax? separate the braided part from the core and solder each part to the separate contacts on the board? don't know if I am equipped for a job such as that, but if I run in to more issues with the wifi it may be the direction I am forced to take, unless they can sort out the whole Wifi USB dongle issue.

What would be the best way to power a USB hub for these units?
[MTCB Android Head Units Q&A] xrapidx:
The guys that have bought these units and had them awhile, would you buy them again from the experience you've had?

If I buy one - and something goes wrong, I won't really have the option to return it. Internationally - we get ripped off on shipping, it would cost more than buying a second unit.
[MTCB Android Head Units Q&A] kwalsh24:
If something goes wrong, you'll likely see them send you the hardware to fix the unit vs sending it back, seems to be the theme with past issues users have had
[MTCB Android Head Units Q&A] 1-2-Hak:
Well I am running again :)

Keylo sent me the replacement parts and my unit is going again - well on the bench - have to put back in car.

The boot time is faster - the radio stores names.

I ran xposed with the app module to make igo full screen so you can see the menu correctly.

I have a automagic script to turn on the loud on bootup and reset brightness.

So what to hack now?
[MTCB Android Head Units Q&A] J0sh_FG:
Those are Great News !!! That's what I was waiting for.

Thanks !!

I'm glad your back in business.

HELP KeiserSozeyFr !!

L O L
[MTCB Android Head Units Q&A] brownstein72:
1-2-Hak, can you share your automagic flows?
[MTCB Android Head Units Q&A] brownstein72:
Also, what are some good dpi settings to use for apps in xposed? I am thinking of Google Play Music mainly.
[MTCB Android Head Units Q&A] booroondook:
Try 160 or 140
[MTCB Android Head Units Q&A] brownstein72:
Finally got xposed working and set the dpi for a bunch of apps to 160 (found that worked best) and force full screen.

Fun fact: kind of a duh moment actually, the iGo app that they sent me to put on my GPS card wont open, gives an out of memory error. I couldnt for the life of me, figure out how to remap the NAVI button on the front of my unit. Well, turns out it is in the settings, under GPS > GPS application (or something like that).

1-2-Hak, I would love to know what setup you are using to set LOUD on at boot and what brightness settings you are using.

The back of my unit has "Camera In" and "AV-IN" RCA connections. the camera in activates when I go in reverse and I have it setup so that my backup camera is connected to both my reverse lights as well as 12v acc connection. I thought this would make it so I can select the backup camera at any time but there is no app to select to bring that feed up, only the AV-IN app which is not connected to anything. Should I just buy an RCA video splitter and hook up the camera to both RCA connections?

My bootup time is 28-30 sec now, which sucks. I am using the google now launcher and it seems to be unresponsive until my OBD device pairs with my system again, this adds even more time. The good news is that my backup camera is selectable immediately and I dont have to wait for unit to fully boot.
[MTCB Android Head Units Q&A] 1-2-Hak:
Will post the flow soon - its not complex - I just need to go to the car and do it.

Basically its a on automagic startup - wait 5 secs - set brightness to auto - launch shortcut to amplifier settings click loud then back.

My startup is getting longer again - noticed this once exposed was loaded - around 25

Will look at my previous work to reduce it again.
[MTCB Android Head Units Q&A] genge:
Hi do you have led button always power on? Because my led go off after start up.
[MTCB Android Head Units Q&A] 1-2-Hak:
Not sure what you mean?

The button led come on with the car lights
[MTCB Android Head Units Q&A] genge:
I mean radio button. When radio boots i see color light . but after radio start button lights goes off
[MTCB Android Head Units Q&A] agentdr8:
I'm suggesting that you try using a usb hub, but only the externally-powered variety (as in powered by something other than the headunit). If you'd rather not try that as a first step, then try utilizing one device at a time, and see if that presents any problems. If not, then most likely having both your 3G modem and your USB stick plugged in at the same time is drawing too much power from the weak 5V rail.

[MTCB Android Head Units Q&A] agentdr8:
You should change the am startservice... command for CarService to just am start com.keisersozey.carservice.SwcMusicStartActivity. There's probably a bunch of initialization that's being done in that activity that isn't being called if you start the service directly.

We cant really help you with that because this thread has some people that say its not that good, but others (including 2 people who have a lot of experience with ICE) say it is very good, so as opinions vary so much we cant really help.

[MTCB Android Head Units Q&A] MasterPrenium:
There is something wrong with USB on 4.4.4. Also with built-wifi (which is connected throught USB bus).

---------- Post added at 09:03 PM ---------- Previous post was at 08:54 PM ----------

Or Linux extend 2/3/4, or any filesystem that is supported by our device kernel. Quite sure we can use a 500GB HDD.
[MTCB Android Head Units Q&A] comptechltd:
I would be inclined to agree about wifi. My wifi performance is abysmal since I updated to [MENTION=853627]coudu[/MENTION]'s rooted 4.4.4. (yes, I have optimization turned off). Funny thing is it didn't seem that bad with the stock 4.4.4 although I admittedly didn't run the stock version that long.
[MTCB Android Head Units Q&A] MasterPrenium:
While looking at dmesg, I saw that the wifi chipset (with it's host usb bus) in re-initializing while having heavy data rate ... I also saw that it tried to initialize with 00:00:00:00:00 MAC Address (which of course can't work).

I didn't have time to test more on my table unit. I will try make some more debug about it.

And for me it was the same on stock 4.4.4.

The real strange thing is that I though it was the same kernel in 4.4.2 & 4.4.4
[MTCB Android Head Units Q&A] agentdr8:
It's all in the implementation details. If you have a service class and every starting method calls it the same way, then it should function no matter how it gets started. But if you pass things to the service different from say a broadcast receiver and an activity, then the behavior might be different based on how you started the service.

---------- Post added at 12:29 PM ---------- Previous post was at 12:26 PM ----------

That looks similar to the issues that plagued the 4.2.2 roms, in which the 1.77 kernel had a properly working wifi module, and 1.86> did not. These types of issues would be really easy to fix if they would just release the kernel source :|
[MTCB Android Head Units Q&A] :
Regarding by black screen issue - I contacted the seller and he provided me with new MCU and Update files that magically fixed everything.

Very pleased.

1. Use a new SD card, format it.

2. Extract the files to the SD card, GPS SLOT

3. Turn off the machine, then insert the SD card.

4. Turn on the machine, the machine will recognize and upgrade the software automatically.
[MTCB Android Head Units Q&A] renedis:
Yes. Still learning a lot and failing multiple times. We haven't find out yet what the best way is to compile it. Also we currently do not have a good functionally recovery working yet.

But it's a good thing we have full source code available for custom rom.

Another good point is that the manufacturer is really listening to us too.. The sales woman registered @ XDA just to listen to our problems and requests.
[MTCB Android Head Units Q&A] agentdr8:
Yes, that would definitely be a non-standard way of starting the same service from different methods.

BOOT_COMPLETED is the suggested way of starting any userland process, whether it be an activity with or without GUI, or a service.

The last foreground app is restored by MTCManager when it receives the "com.microntek.startApp" intent.
[MTCB Android Head Units Q&A] typos1:
We know how to do all that, lol, the main thing everyone will want to know is whether its a new version or not, what Android version and date appears in system/settings ?

---------- Post added at 09:49 PM ---------- Previous post was at 09:47 PM ----------

Ah, you mean youre working on Red's ROM, I thought you meant you were starting your won ROM as well.

We had someone from KGL on here for a bit, but she didnt last long.
[MTCB Android Head Units Q&A] :
I thought I would copy the instructions for completions sake. This version installed without any user interaction

Version? Dunno, I'm in the house
[MTCB Android Head Units Q&A] MasterPrenium:
For sure ... The kernel isn't a standard linux kernel ? (Never looked to Android kernels). Or maybe specific from Rockchip ?
[MTCB Android Head Units Q&A] renedis:
No.. reds rom is on 1.0.9. I'm working on the stock rom 1.1.2. If successful I'll try to compile a complete custom rom from source code.

then we'll have 3 in total.

- Mine

- Reds

- Zaphod-Beeblebrox (with an AOKP build)

But I'll stop cluttering this topic with non related information about the HuiFei! Thanks again for all the input and information!
[MTCB Android Head Units Q&A] agentdr8:
Yes and no. It's specific enough that a kernel from another rk3066 device probably wouldn't work, unless it had the exact same hardware/components inside.
[MTCB Android Head Units Q&A] typos1:
Well, let us know when you can, thanks.

Right, so 3 customs ROMS !

OK :)
[MTCB Android Head Units Q&A] MasterPrenium:
Thanks, I'll take a look a little bit further.

Found these sources to built a Linux Kernel for rk3066 : https://github.com/Galland/rk3x_kernel_3.0.36 .

I'm skilled enough to customize and patch my own Linux Kernel... I will check if I can do something with our devices ...
[MTCB Android Head Units Q&A] superlover911:
Thanks but tried disabling, GMC simple (#41) and a couple others to no avail. Might just have to order a SWC module and hard wire into head unit. Sucks because I've seen a video of the same head unit in the same vehicle and his SWC worked out of the box. I will make a video of my troubles and send it to the seller and see if he can come up with a solution.
[MTCB Android Head Units Q&A] agentdr8:
Yes, I agree that a service should run the same no matter how it's started. I just wanted to point it that it may not always be the case, even though it should be.

Map direction when not moving

Hello,

I have a following problem: when not moving all the map programs turn north. So, when driving in traffic, the map constantly changes view direction.

I guess thats because our devices are not equipped with a compass, so the only way to get the direction is from the GPS movement. I'm a programmer myself and I think it would not be too hard to write an app, that would set the last movement direction when not moving, but that would require turning on GPS position simulation.

But maybe anyone have already fixed this issue? :)

KLD 2.20 MCU improve sound

I agree! The sound quality increased significantly! Now is acceptable, but I will buy external amp. Maybe the radio reception improved too. Today was very rainy here, but the radio was better then before. But this was a short trip so I need some time to confirm that.

And it can remember the latest volume level!

proximity sensors with smaller DPI

Hi, my firs post

I have Erisin 9000A (klyde) with latest KLD_4.4.4_800x480_141223_rooted_light_reparted_init.d_v4.2 with MCU 2,16.

BT ODB, all google services, spotify, stable WiFi, can bus

Problems:

1) Radio reception - not so good as original radio (wv passat) - but with MCU 2.16 much better.

2)3g dongle not working - huawei e173, tried PPP 2 widget, UMTS manager - nothig.

3)When I change DPI with build drop to 200 everything seem ok, but when the car (MCU) shows proximity sensors they don't fit into frame and i cant see raer distances - picture below.

Any ideas haw can i solve this?

Do you know witch app (apk) is responsible for the frame around the car with proximity sensors? Maybe when i change this app DPI via xposed apps the frame became bigger and i will see whole car with proximity sensors.

Sorry for my english.

Tasker, AutoRemote, Bluetooth

If this isn't the right place for this question, please let me know where to post it.

I have Tasker and AutoRemote installed and configured on both my head unit (KLD, coudu's 4.4.4 rom, mcu 2.20) and my phone. When I'm at home with the HU connected to my wifi I can send messages from it to my phone. If I disconnect from the wifi, however, I'm unable to send messages even though the documentation for AutoRemote says you can send direct messages over Bluetooth. I've searched all over for any info on why this won't work and haven't found anything. Is there a missing Bluetooth capability on the HU that doesn't allow this or am I just missing something?
[MTCB Android Head Units Q&A] agentdr8:
It probably requires a BT profile that these headunits don't have. Maybe OBEX, MAP, or FTP. Not sure what the AutoRemote app is expecting on the headunit side.

Just got done installing my RFASWC. The ASWC-1 should be the same, aside from the wireless part.

I connected the female 3.5mm adapter to the output of the SWC box, and connected the brown/white wire to the key1 (brown) and brown to the key2 (brown/black) on my GS. There's also a black ground wire on the GS harness that should be connected to ground. The red on the SWC box goes to a switched ignition wire (ACC), and the black also to ground.

As for programming, I changed the programmed radio type to 10, which should be Clarion 5V. Once everything is connected and the headunit is booted, go to Settings->Steering Wheel Controls. Press a button on your SWC, and then press the associated function on the screen. Continue to do this for all of your buttons and hit Save.

For Alfa romeo there isnt a specific unit so i have a universal klyde unit.

In the can bus menu i can choose ALFA ROMEO option so i think that the device support it

For steering wheel support I use a this adapter

http://www.ars24.com/Zubehoer/Lenkradinterfaces/Pioneer/ACV4-Lenkrad-Interface-Alfa-Romeo--Pioneer.html

I think that it gets the can bus signal and convert it to resistive one.

Before this HU , I had a pioneer one so i used this adapter from the can bus to the pioneer so i can have sw control working.

My installer cut the wire that was used for pioneer and connected the two cables to the key1 key2 (i think).

Now with the help of this adapter i have can bus --> resistive-->klyde unit.

I believe that the can bus harness is this.

I also have blue and me in the car
