As I couldn't get forward with this issue up to now I'd like to start checking evaluation of the chain app -> MCU -> DTVbox and try to find out who is responsible that no menu screen appears.

So I'd like to ask whether there's someone out there who has a DTVbox up and running with touchscreen operation.

If so, could he/she check the App version and possibly the fingerprint?

On my radio installed is an app called "Digital TV" V1.0 (MTCDTV.apk in system/app as of 2014-05-08 10:40:43am with filesize 62443 bytes.The fingerprints [shown by ES File Explorer] are: MD5 39d5 ... ... 408d / SHA1 2e6b ... ... 5b7d)

Note: Dependent on the TVbox model selected in the factory settings menu either MTCDTV.apk or MTCATV.apk is switched active and displayed on the apps screen.

Thanks in advance for your support!

Hi to all.

I have this unit:MTCB-MD-V1.73.What is thet?????
[MTCB Android Head Units Q&A] ProfessorKnox:
Thanks for the info about additional usb. I don't habe any knob - just keys. But I found in the internet an Android 4.0 model looking the same as mine but with front usb. So looks like you are right with common pcbs and seems to be a chance that there are already pcb tracks to just solder a connector - and make a hole for the connector into front plate - which may be the real challenge!).

Here we go :

Device needs to be rooted, adb must be setup correct. (This looks like a easy tool for Windows : 15 seconds ADB Installer)

I did all that stuff in linux, since i use linux a lot, but once you are connected with adb, commands are the same ;)

Apk i use on my Huifei :

(This is just a example, other wifi adb apk's are fine also)

When adb is started on the Huifei, open your command line on the pc. (Terminal in linux, cmd in Windooze)

Navigate to the folder where the files are stored. (In my case it was Arbeitsfläche/kernel)

Then follow :

I made a pic of all the commands.

The output seen in the green fields will not be exactly the same (KB/s, s,..) but it should look similar.

The red fields are the commands

When finished, just reboot your device, and the kernel should be booted.

Just on thing :

The commad that will connect you with ADB must be taken from the app you use. (first red field)

You have to take the commands given by the apk !!

Rest of the commands:

adb push kernel.img /dev/
adb push flash_image /dev/
adb shell
chmod 755 /dev/flash_image
dev/flash_image kernel /dev/kernel.img

1.77 Kernel + flash_image

Hope this is ok, since im not so familiar with howtos...

If something is unclear, i will try to help ;)

You cant root the unit using Wifi ADB - use rootmaster as mentioned in my previous post ...

Just the static PNG images, I need the location for the animated files
[MTCB Android Head Units Q&A] optx:
Just place a static png there, it will get the animation every logo gets. (still dont know how this works....) :p
[MTCB Android Head Units Q&A] Navall_75:
i did not know that, thank you :D
[MTCB Android Head Units Q&A] ProfessorKnox:
Would think that the animation is performed by the boot code. It's 'just' moving a 'shadow' across the screen and thus across the logo. You may prove my assumption by creating a 'full screen grey' logo.
[MTCB Android Head Units Q&A] 1-2-Hak:
In the system/mtc is the animation zips you can change. Create an animated boot logo - change the name to one of the ones there and then select it in factory settings.

US 3G USB Phone Dongle

I know some models that work with these HUs have been posted already, but I'm looking for one that will work in the US on the T-Mobile network at 3G or 4G speeds. Anyone have any experience with that? When I use my phone as a hotspot my USB devices (SD cards and jump drives) unmount randomly. I've noticed other people have had the same experience. I'm not always satisfied with T-mobile's coverage away from cities so I guess if one of the other companies has a reasonable data plan I might be tempted, but I'm with TM with my phone so I'm starting there.

Problem with FM Radio reception

Hi,

my Porsche 996 PCM 2 replacement is in the Car and is somehow working. But I don't get any FM-Radio reception at all! I connected the Radio over the DIN inlet with a Fakra to Din adapter to the Fakra car Antenna connector. I also connected the blue ANT Wire to the cars Antenna amplifier. Any Ideas what to improve? It is the same with all receiver chip settings. The region is Europe.

The second thing I'm experiencing is a white noise which is there as long as ignition is on. I can hear it even when the radio is of, which make me think that it must be related to the Amp wiring.

Many Thanks in advance!!

Karl

Does an newer or alternative radio app exist for Erisin ES9401 (KGL 1.77) ? Built in tuner is a TEF6624 or a TEF6606, selectable TDA7706 doesn´t work correctly.

Only alternative that I'm aware of is a usb tuner with Wavesink or SDR Touch. Neither of those is very car-friendly, though.

Hey guys

I fitted this unit to my 330ci today and was immediately happy, worked well and was an easy fit, once i had set it all up i left it playing spotify while i tidied up the boot, not sure if it had anything to do with it, but i moved the fakra cable slightly near the fuse/filter box and the unit died. I checked at the connector behind the unit and there is 12v present, i have tried resetting by just using the reset button and the reset and power buttons.....and ideas anyone please????

Changing inputs

Hey folks - slightly new to the site....

I recently installed the knobless KGL version. For the LIFE OF ME, can't figure out how to change the input - such as the A/V or Aux... There is an AVIN app, but all I get is the exclamation point - same as when I try to 'watch' TV

MCU flash

I did not try though ;

Is "flash-only MCU" possible under recovery ?
[MTCB Android Head Units Q&A] ProfessorKnox:
Note: The subsequently stated connector designations and wire colors relate to my unit and may differ from yours.

AVin: Have you any valid video/audio source connected to the respective RCA connectores (brown wires, VIDEO IN, AUX IN L/R) at the back of the HU? When a valid video signal is detected by the HU the '!' will disappear. If only audio is connected, then audio should be emitted on the speakers but yellow '!' will stay on the screen.

TV: Have you connected the TVbox at the back of the HU (white 10pole rectangle connector) which they advertise for that purpose? W/o this box of course no TV reception. Regarding the '!' the above said applies.

DVR function: For this you need an USB cam connect to the USB port at the back of the HU. I'm using a separate dash cam so I haven't tried this yet and can't tell you which types of USB cams work or whether you definitely need to use the one they advertise.

Rear camera: Reverse cam needs to be connected to the respective RCA connector (violet wire, CAM IN) at the back of the HU. Power supply for that cam are the red/blue wires CAM IN/GND. Cam video display is activated either by CANbus or by grounding the BRAKE wire (pink) located at the harness you connect to the car connector.

Hope this helps.

Not as far as I m aware, unless you can find another type of unit that uses the same radio chip and the same MCU.

3G dongle configuration. Empty triangle

hi there,

I just get the knobless KGL version aswell. v1.77

They send me with the 3g dongle Huawei E180.

But something very strange happened to me.

The first time i've plugged the 3g dongle, the unit ask me for a pin, and connect without problems.

Now is impossible to connect, there are an empty triangle near the WIFI icon, but that's all.

I can't find any menu to configure the APN or 3g connection, i tried to google it several times without result. I tried both USB connectors and i checked with my computer that the 3G dongle works

Anybody can help? I can't use internet.

I tricked it to flash only MCU by making update.img invalid, therefore it won't pass the integrity test but MCU will flash just fine.

Cracking sound

Someone said that at the end of updating process there is one short cracking sound which nearly destroyes all connected speakers.

Is this true for all image versions ?

Because of the quadlock jack you unfortunately can´t disconnect speakers.
[MTCB Android Head Units Q&A] Stank0:
Yeah, there is a loud pop when the device restarts but by far not loud enough to destroy speakers IMHO.

It's kinda like when you turn off an amplifier in any audio rig.

[MTCB Android Head Units Q&A] idr3s:
I posted a prob here I had with the button's lights being ON regardless of the headlights ..

Was told to cut a wire and fix it to illumination instead of 12v.

Well firstly I'd like to mention something I notice..atm when i turn my headlights on/off, the screen brightens/dims a little with no change to buttons lights..means the correct wire (orange) is connected properly.

So yesterday I removed my unit and cut the wire to see what happens and well.. the button lights went off and the screen stayed bright as I switched the headlights on and off (no change) ..

So what I'm saying is my units button illumination is basically a software problem and because of that I need to know if someone can maybe give me a xposedmod or something that will fix this.

Would really appreciate any help!

Wifi issues :(

Hi everyone.

I would love to have your help with an issue regarding wifi conenction.

My device always got wifi signal from my house outdoors very well. I managed to get into Chrome, surf the web, get into Playstore, Facebook, Emails....everything.

A few weeks ago something must have happened because even if I get the signal from my router (sufficient and good) nothing seems to work regarding internet.

I have the connection but everything stopped working.

On Chrome I get the message Error SSL. I checked wifi settings and I don't know where or what to change. Someone told me that if I got into settings and change the date and time it could solve. And the fact is that it worked.....for a day or two. But now it happens all the time.

What seems to be the trouble?

I know I haven't changed any settings whatsoever.

I checked at my friend's place where I had also a good connection and it happens exactly the same.

Any hints? help?

Thanks....:(

Just a friendly reminder. DO NOT BUY ANYTHING from Keylo or Shenzhen Kai Ge Le Electronics Co., Ltd. They sent me a unit that went DOA in a week, but not before it blew out two speakers out of my MKV, they sent a few parts to fix the unit (which didn't work) and have now gone silent. They haven't responded to the Paypal inquiry or the Alibaba inquiry either. I've paid $500 for a paperweight.

ge to my car :( fingers crossed
[MTCB Android Head Units Q&A] typos1:
It cant go "dead on arrival within a week", its either dead on arrival or it goes dead later, in which case it wasnt DOA.

A few people have had problems, most have not, I am sorry that you have had, but you should open a paypal dispute and/or an alibaba dispute and they will resolve your issues for you. Indeed, with alibaba the money only gets released when you acknowledge that the item has been received and is working and you have the option NOT to tick that it is recieved and working, in which case you will be offered a full or partial refund, you may even get it for free. I take it that you marked the item as received and working without waiting a week or so to see that it worked ok ?

We can try and help you with your problems here, maybe find out why it happened (how did you wire it in ? do you have a built in amp ?).

But I fail to see what you are trying to achieve with posts like that as the majority of people in this thread have already got the KGL/HuiFei units, its not really going to help anyone is it ?
[MTCB Android Head Units Q&A] RoLoYYZ:
While not technically DOA, I'd say something that was wired in, checked to see if it was working, then left for a week and on the next boot up it started to fail.. I'd say that's pretty damn close. The amp chip within the unit blew, taking out two of my speakers. No, I don't have a built in amp. Prior to this I had a WinCE unit which still works flawlessly, albeit a bit slow, and before that I build a carputer from scratch for my Lexus SC, custom fabricating a 2 din mount our of aluminum, building a WinXP mini epa computer, designing the power supply... I'm no stranger to electronics inside and outside of cars.

I gave these people plenty of opportunity to fix the issue and they haven't. Bottom line, I paid $500 for a unit which died after a week, it did damage to my vehicle. I've got a paypal and alibaba dispute on the go already. People should be alerted to bad sellers out there and I'm trying to notify them prior to purchase. I personally had watched this forum intently prior to my purchase and wish to hell someone had noted issues with these units, as I'm not the only one. So, yes, I think it is going to help someone.

Golf MK4 install

I was wondering if anyone has successfully installed one of the HuiFei units into a Golf MK4.

I have had an issue with 2 separate units where after install the DVD+WiFi+Bluetooth+GPS do not work.

Other bits are OK. Radio, Music, Video etc. Sound is fine.

My suspicions lie in the harness that was provided to connect the head unit to the car.

The MK4 Golf looks to have non-standard ISO pinouts on a standard ISO connector. This ended up with the switched 12v ( acc ) and constant 12v connections swapped. I don't think this is a particular issue apart from the Radio losing it's tuning every time the unit is powered off.

The other issue is that it ended up with +12V supply connected to the "AMP" out from the head unit through pin 5 in the power connector.

Has anyone had better luck?

If so can you share how everything is connected?

Thanks

Custom Launcher

I have been playing around to get a more car friendly Launcher in my Midnight blue theme to match my custom radio app.

I am no designer but it is definitely better and easier to use in the car. Happy to hear/see some recommendations of how I can make the menu better. I like the simple text.

I used ADW launcher and Music Visualizer to create the theme.

The custom icon is done with Automagic and it monitors Wifi connection and displays if connected to my phone or home wifi.

Automagic also used the twilight plug in to detect if the sun has set or risen and dims the screen for what I call day or night mode. This is also displayed on the custom icon.

I have also customised the boot logo...
