Thanks for your comment. I would have done that If I know how to extract an apk from an img file.

Thanks again
[MTCB Android Head Units Q&A] doctorman:
can you please post a link to one on google play store that works with usb ?

or can you please post the apk file to one.

I have looked and can not find one

People have tried unsuccessfully in the past to set up the normal Android screen lock, but Tasker apparently has a screen lock function.

You cannot use any other radio app other than the ones for this unit(you CAN use the older radio apps from 4.2.2 and 4.4.2 though). Have you enabled RDS in factory settings ?

Jeez, theres months and months of work for you there, transferring all the info over ! :eek:

Have you looked on the fileserver linked to on the first page ? There are ROMS going all the way back to JB 4.2.2 November 2013 on it.

Rooting does NOT cause any "issues", not sure where you got that idea from.

---------- Post added at 01:55 AM ---------- Previous post was at 01:51 AM ----------

Not sure of any that work with USB, I thought they all worked with wifi rather than usb, just google "screen mirroring app", or extract the apk from an update image.

Its ok, its quite easy to extract an apk from an image, google is your friend :)
[MTCB Android Head Units Q&A] doctorman:
well that is the point

USB screen casting

have you seen an apk that does that ? which firmware would have that app and what is that called on that rom.

you answered me as if you know what you are talking about but it seams like you did not understand what

i was asking.
[MTCB Android Head Units Q&A] typos1:
They all come with a screen mirroring apps, Klyde told me recently that the RK3188 quad core units have an app for it, as though it was something new, another user commented that there was already an app for it on the RK3066 dual core units, so it was not anything new.

I did say "there is nothing special about that app AFIK", are you saying that that app is different from all the others because it is usb screen mirroring and not wifi screen mirroring ?

Anyway, you can download a quad core image from the fileserver linked to on the first page and extract the apk from that.

Dont think we ve had any quadcore JY firmware yet, but theres KLG and KLD quadcore there.

if it is not too much trouble would you please see if u can extract the apk

The modem works fine via the front USB port.. I installed the Mobile Network Settings app, in the app I made a profile of my Internet connection. And rebooted the HU .

I reverted back to stock kld 4.2.2 20150115 with mcu 2..22 to test differences.

The only one i noticed that i liked better is Radio RDS is working good.Not perfect but good. It sometimes complicates characters but it is ok. And signal with this radio is better.

Is it possible to bring these features to 4.4.4 roms?

One quick question concerning viper4android. Running Malaysk rom with viper4android installed and using the stock music player. Animation is turned off, however when the unit boots into music player, viper4 android does not kick in till I press the home button and actually minimize the app. Anyway around this, viper4 android kicking in since the beginning? I suspect that dsa might have an answer with install-recovery but Im afraid Im bugging him all the time. :)

Thanks! I will give this a try today.
[MTCB Android Head Units Q&A] apachesp:
Thanks for the answer.

For future BMW users... the 12v+ in the harness is not constant, it turns off after some time, so the radio will lost all presets (radio tunes, hour, date, etc).

So you must find a 12v constant one. (i'v already order a fuse tap)

When it arrives I can continue, but almost sure you dont need to connect ACC cable, and already sure don't need Key 1 and Key 2 cables.

Radio presets not sticking on JY unit.

Hi guys, just installed a RK3066 JY (branded Joyous) unit in my wife Forester.

Got it running pretty nicely, she's pretty stoked but there is one annoying issue. The radio app looses saved stations so have to retune after every restart.

I used an ISO to Subaru harness and double checked the continuous 12v is wired correctly. It's receiving over 12v even when ignition is off/keys out.

Is this just a bug in the stock radio app? Any known fixes? Do I have to root and install a different radio app?

Cheers.

Just a quick idea, I stumbled across some weird behavior in the past when I messed with the system settings behind the 126 password. Specifically, try ticking or unticking "WHEEL3" and/or "RUDDER" Maybe they will help with your multi pressing issue?

Sygic

Has anyone managed to get Sygic to install lately onto any of their units?

When I install, and download maps, I get a black screen for the map. Going back into managing the maps, it often goes into a different region language setting, although the region is correct.

Any fixes?

Cheers,

Chris
[MTCB Android Head Units Q&A] CARRisma:
It's a known fault. Which HU have you got? I get the impression that only JY are affected by this fault. I've been in contact with Sygic Technical Support. They eventually gave up and refunded me. A WORKAROUND for this fault is to connect a 3G dongle then start Sygic. You can even connect it, wait for it to connect then disconnect it before starting Sygic and that will get it to work. It seems Sygic is now reliant on something that the 3G dongle provides. I suspect it's something to do with location.

MUTE - fine

DVD -fine

BAND (radio) - fine

HOME - fine

BACK - MUTE

VOL- - its vol- or Satnav (tomtom go)

VOL+ - working as vol- or nothing

NAVI (LOUD)- not working at all

i try lots of combination to change keymapping in Factory settings screen but anyone working fine.

Can someone with this same unit help me set up keys correctly PLEASE.

I have a KLD head unit. Using Coudu's 4.3 firmware. After picking North America and maps I want, it will download but still be black. If I go to the Sygic store, it will randomly change regions to Europa or Asia etc. It will download maps as well. I really like the GPS, wish I could get it working. I don't have a 3G dongle to try.

I have a KLD unit and the radio presets are lost after a hard reset (for example if I force a reboot through xposed). But not if I turn off the car and come back later.

Does the MCU need constant 12v to keep the presets saved? I find it strange that the radio app doesn't save the presets into internal storage like other android apps.

Is there a way to save radio presets without using XposedMTC module? XposedMTC does the job in this regard but gives me other issues when using the mode button on my steering wheel to cycle through sources - so I prefer not to use it.

Yes, I'm almost sure it needs 12v constant. As mine is connected to a switched 12v and lost the radio stations every day (I'll solve it when I receive a piece im waiting for)

Ready to Update :D

Hi All

I'm almost ready to upgrade my rk3188 1024x600 to latest firmware and malysk release.

But I wanna be sure i dont make any mistake. So .... let me be sure.

My radio, as you can see in the attached file, is MTCB-KGL-V2.22 -> First Question... The Car Is a BMW, and wasn't it supossed to be MTCB-KGL1 or MTCB-KGL5-V2.22 ? Mercedes and BMW should be? Can I Brick the radio if using a NON BMW on BMW ? or just would see the Canbus non working, so i can upgrade again.

The Android is 24042015

I cant make a backup as im not root, but have no info inside, so i'v donwloades the MCU and Android original from file (THe MCU is really small, only 50k!!, Amazing) As you can see in second Attach, i'v downloaded The OLD ones and the NEW ones.

My radio has no Front USB, so I bet the radio can enter auto in bootloader mode.

So, to begin with the update.

Copy MCU and Android to the root of the SD Card.

Plug the SD Card in GPS SLOT

If I don't see a pop up, i'll restart the radio

It will ask to update or not. -> Say YES.

Once is updated, removed the GPS SD card.

Change the languaje from russian to spanish..

AND ENJOY? :D :D

The Radio is working fine, but I wanna use the Front Park Sensors, and with this firm/android only works the rear ones.

Thanks for the attention :)

AirPin is actually old version of this app

AirPlay/DLNA Receiver (PRO)

which works via Wifi not USB based on what I read,

JY told me the following about easy connect app

"Dear friends, this APP is genuine, to be purchased, cost $ 15, the dual-core is not necessarily be used, thank you! Good day!"

"Many guests are asking the same question, I assure you, this is not a simple installation APP

[E-LINK] APP before our guests need factory setting, which is not possible to do!"

EDIT: spoke with a bit better person from JY that tried to get the app working on dual core and could not.

so installing the easy connect app will not magically make it work on dual core unit.

[MTCB Android Head Units Q&A] saifbarry:
This would be more of interest for people in the GCC. (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE).

I bought this a week ago from Roadmaster in Riyadh, Saudi Arabia. There is more info on the head unit on this page. Hardware spec wise it is an exact clone of the HuiFei unit except that HuiFei doesn't have a model for GM SUV trucks but Roadmaster does.

Unit cost me SAR 2000 (US $534) installed. Bought it from Al Amoudi Trading. Came with a two years warranty. Its a bit pricey compared to importing it from China, but I think local availability and warranty trumps the savings.

Install was plug'n'play except for one brown wire that the installer cut so the head unit doesn't switch to the reverse cam input when the car is put in reverse. The wire cut was on the head unit and not one of the car's wiring. It was installed in a Tahoe 2013. All of the steering wheel buttons work out of the box. No configuration required. However, now the cars warning chimes and indicator ticks sound horrible. But I consider this a small price for the feature rich head unit upgrade.

The HU came with two USB inputs, one on the rear and one on the front. Also comes with an IPOD connector. I don't have an iAnything so can't test if it works. I'm using an old USB hub connected to the rear USB input with a Huawei 3G dongle. Again, no config was needed it just worked and connected to the Internet.

Installed apps are slightly different than the screen shots I've seen here from the original HuiFei unit. The HU also came with a couple of Roadmaster apps. I rooted the HU using the instructions on the wiki without any problems. I installed Xposed and have done a bit of customization and removed a lot of the built in apps. Primarily I'm using Viago and Google Maps for navigation. The HU comes with two launchers and you can select which launcher you want in the settings area. I tried installing other launchers and they showed up in the settings but I couldn't select them.

I've also been running the HU in 45~48C (111~118F) temperatures for a couple of hours with no issues whatsoever. There is a slight whining noise coming from the speakers but it is very faint.

Here are some pics.

[MTCB Android Head Units Q&A] J0sh_FG:
The app stops about 3secs after you started it. Maybe because there's no Ipod/Iphone connected hehe.

This Ipod/Iphone output seems to be included in the back pannel of v1.77 HuiFeis.

I'll try to upload the app tomorrow but U may need this connector in order to make it work.

Hi Guys,

First time posting on this thread after finally going thru 124 pages. I seldom see such great support for a china product. I'm really looking forward to get one myself.

Is Shenzhen Kai Ge Le Electronics finally started selling single units now? I've search on Aliexpress for "Huifei", and i see many listings coming from Shenzhen Kai Ge Le Electronics. I'm wondering if this is real as the feedback score is really really low as in less than 5?

Here's one of the unit i'm looking forward to get. It's a universal unit.
