That explains why, thanks I installed on the ext sdcard. Once I installed in the internal flash it works now:o

---------- Post added at 09:23 AM ---------- Previous post was at 09:13 AM ----------

NaviPR upload the apk in post #12459 . Download and install it, and there are two way to "connect" the unit to the phone. Either by wifi hotspot or USB cable, but I only tried wifi hotspot on my iphone 6. Enable personal hotspot and link the unit to the phone with wifi connection, then on the phone you will see easy connect "Mirroring" and you have to manually connect to it, the unit will now mirror the phone.

Airpin is another way to link to the phone but it seems to cause a lot of screen artifacts that I find it unusable. :eek:

This unit does not seems to be similar to HuiFei, so you may look for the AN-21 unit thread to see how to root it.

Tried the Easy Connected app that was uploaded here on my dual core JY unit with android 4.4.4

installs fine

runs okay

USB debug activated on my phone

USB connected

HU recognized my galaxy s4

2 options here: videos on phone...

shows all the video but does not play them

2nd option screen mirroring , pretends to connect to the phone but on the HU unit you get a blank black screen, audio connects via Bluetooth and work but no screen.

a program called Drive Mode is installed on the phone the irst time it connects to the HU with the Easy connected app running.

the Easy connected app calls home and and checks for update

it is made by company call BITCAR

I did not find any ifno on it.

there is a problem with 4.4.4 android with bluetooth DUN and tethering in many apps I tried not single one works via BT or USB.

Bluetooth screen mirroring apps also wont work, I am hoping it is just the android 4.4.4 issue and not a HU issue. so in that sense looking forward to lolipop on our HU.

Easyconnect app would have been the best thing and I will bug the chinese sellers about it...

Wifi is useless for screen mirroring while I drive as there will be no set wifi and the phone wifi needs to be open to access possible public wifis arround..

so for me USB is the best way to mirro the screen or share the internet to my HU in long drive so I can use Waze GPS from my phone or on the HU directly and have internet for it from my phone.

I was checking the datasheet of RTK 8188CTV, it is a 1T1R WLAN chip, do you think it is possible to mod this with a 2T2R chip RTL8192EU and solder it on the board. Any issues that can occur to increase the wireless speed?

Those USB wireless can be used to get the 2T2R chip

Looks like they are not USB ports, maybe they are used for MCU programming?? I'll try to find IAP datasheet.

But I still don't know where is USB1 connected. I have 3 back USB connectors, all of them recognized as USB2 in File manager, and only the first stick attached can be accessed. I don't have a front USB.

Can someone who owns an unit with front USB port confirm that front USB is recognized as USB1?

I just tested on my desk on a KGL 4.4.2 connected to a phone Galaxy Note 4 via USB.

It works perfectly:

Connexion OK

Bidirectional control from screen.

No lag for video or control.

The video compression to adapt the res is really efficient: from 2560x1440 to 800x480, the image from waze is really good...

Well... I continue with the same problem... I want to open today to check if it is any phisical problem...

I install KGL1, KGL4, KGL 5... And now I come back to original one, KGL5 2.22... no one works... I try all options...

Canbus : no, Can bus : 23_BENZ_B200(Simple) and Canbus : 38_BENZ_B200(Union) and activate and deactivate the option "wheel3" Anyone knows what do these option?

I think these problem it is to MCU level, then don't care which one android rom I install. It is right?

Could be my canbus unit bad? with my unit come 2 cables, one for w211 and one for B200. I use the w211 because my car is a w211, and the pins seem fit between them... must I try other cable set?

I'm very sad!!! :(((( HELP!

Malaysk,

Your latest rom is really awesome! I love everything about it. Thanks for the efforts :good:

I have two concerns though:

1. Launcher crashes when I try to add a Direction widget to the homescreen. See the video here

2. When I open the app Vehicle, it shows live reading from the car sensors which indicates that I have the right connection to the CAN bus and the right CAN bus settings in the Factory Settings. However, it does not show any pop-up or msg when a door is open or something. Am I missing something here? See the video here

-farisallil
[MTCB Android Head Units Q&A] Malaysk:
1. I never use the regular launcher. I use NEXT launcher and therefore can not say anything about this error.

2. Do you work at this factory firmware?
[MTCB Android Head Units Q&A] ramdani1978:
Hi there..

From what I already tried, unless you had some kernel builder skill, you can only change wifi board or wifi dongle with the same chipset with the original wifi chipset (RTL8188CTV) like this one: http://www.aliexpress.com/item/New-...USB-WIFI-module-For-tablet-pc/1833440798.html

The TH8581GA falls under Ouku&co (single core Freescale device). I think you're better of looking at the Ouku-dedicated forum for a solution.
[MTCB Android Head Units Q&A] typos1:
This is probably because its not conventional BT, its basically a BT handsfree module and Android does not really have much to do with it, it is mainly MCU controlled, its not BT as you would have it on an Android phone or tablet. A BT dongle may work better, they are very very cheap nowadays, may be worth trying.

Been meaning to ask, Priusfan, which unit has the best sounds quality ? The HuiFei type units or the AN21-U ?

Malaysk a few pages ago you posted some screenshots and the equaliser and amp screens were different, is this because of a new KGL MCU on your unit, or have you modified them yourself ?

All sorts of MTC apps appear when the CAN Bus settings are changed in factory settings.

ALL these apps are included in the ROM, they are just activated for different cars, so as his is a VW he would have changed the CAN Bus settings and a VW compatible app would have appeared. However if your car is not a VW it would not work (it does not work 100% with all VWs).

If your unit is a universal unit you would also have to connect the CAN Bus lines to your headunit for the app to function, you may or may not need a CAN Bus adapter (no one is sure if the CAN Bus lines are interpreted by the adaptor or they go straight to the headunit).

There may or may not be an MCU app in the ROM that works with your car.

And of course your car has to have CAN Bus.

So you have modified the screen layout yourself then ?

This is like trying to order a rare hamburger. I have to keep insisting. ;)

Baby steps, please.

1) Download the above file. TO WHERE? On the Head Unit? On my phone? Both? EDIT: HOW do I download to the head unit? Do I need to get it connected to the net first or can I transfer the file via usb?

2) Connect my phone to the Head Unit via the USB. OK, I can handle that one.

3) Enable personal hotspot. HOW? If it's via WIFI, then I have been unable to. Either because of 4.4.4 issues or Verizon doing a good job at locking Unlimited users out of HTC M8 phones.

4) What settings do I need to enter? You imply none, but I want to be certain.

5) What do I need to do on the phone itself?

Honestly, I do thank you for all your help. But I'm just a caveman and you are handing me a hammer, pointing to a pile of wood, and telling me I have all I need to build a house.

No need for OTG....

I used the USB cable for charging (micro USB / normal Plug).

I tested with success Galaxy Note 3, Galaxy Note4, Sony Xperia Z Ultra on my "old" KGL on my desk.

I tested also on KDL with GN4 & GN3 : It works really well.

I plugged at the same place where you can plug an USB Key.

If an USB Key is not recognised, Try to plug to another place in the back of HU, see attached picture...

Yeah - I tried to use my phone to stream music over Bluetooth to my KLD unit and the quality was not good. And I wasn't streaming the 'net - it was locally stored on the phone. I now have a SD card with my songs on it. I do have a Verizon Jetpack with "pay to play" that I will use on long trips and I can stream Spotify or Google Play over that. But it's expensive at $90 US for 10 gigs... Hence my use of it only on long trips...

Buetooth streaming by IHeartRadio and the phone's built in player have been fine with my HTC M8 and JY head unit. I just dislike having to cue up the phone with the correct player and then only being able to play/pause/skip on the head unit.

Maybe some day I'll figure this stuff out so I can customize and upgrade my head unit to do all that I want it to do.;)

did yours come pre-installed or you just use the apk that was posted here?

I know it works on the units that it is pre-installed on from China seller...

question is can we just install the easy connect .apk and use it on other units or Joyous people were actually correct and the only way to use it is to have it activated by connecting it to their cell phones in china.

as I said mine installs and connects but I get a black screen when I try to mirror the screen.

found the webiste that makes it http://www.carbit.com.cn/

an email for them would be support@carbit.com.cn

I have emailed them but not having high hopes
[MTCB Android Head Units Q&A] priusfan:
It was not installed on this HU (but I paid for it when ordering).

So I installed the one from the link on this forum.

And it worked... (the car was connected via Wifi to the net and maybe there was some kind of validation...)
[MTCB Android Head Units Q&A] Alphas:
That was what I meant, remove the whole board from the USB wifi and replace it on the PCB. Of course this require desoldering and and reconnection of the antenna.

Exactly, since it is the RTL81XX, the driver for both 8188 and 8192 are the same since realtek releases drivers for chipset that are similar in functions. In theory this can help to increase the range AND the throughput of the wifi signals.

Actually, dont trust JY, there is no validation required for easy connect app. I installed it and the apk worked instantly, much better than the Airpin app which gives horrible artifacts after only a few minutes of mirroring.

KGL-8102

Hi there,

I have placed the order for the KGL-8102 screen for Land Cruiser.on Alibaba

Although this can still be changed and that depends on the answer I get here.

I just noticed on the link showing the device that it had an "option" for HD resolution i.e. 1024 * 600 instead of the 800 * 480

Now reading the forums here it seems that there are no devices with such a spec by Hui Fie.

Can someone verify if this could actually be true?
[MTCB Android Head Units Q&A] xrapidx:
Crap :(

Guess things might get ugly then - I've had two quotes to return the unit, FedEx and DHLExpress, both $350 - according to PayPal, they require me to return it, even though I asked the seller to double check, and it doesn't really matter that half the things advertised don't work (3G, my iPod and the radio) - my credit card, however, requires everything working - or a return/refund/replacement at the sellers cost.

1.6GHz CUP+1G RAMAndroid 4.2 Car DVD Player for Honda CRV CR-V 2012 2013

with GPS Navi Radio TV BT USB AUX DVR OBD 3G WIFI

I was trying to make software update. Unfortunately update did not go through easy.

After unit updated firmware unit went to dark screen and never restarted.

Now system boots only to three options :

restore

update from SD card

restore from backup

After system updated firmware power button does not start system at all.

When I press power nothing happens. To start system I have to hold power button and press reset and then I have to hold power for few seconds.

Finally starts but only to those three recovery options.:crying:

I did not make backup before I started and this was the biggest mistake

Does anyone have this unit?

Can anyone make backup or restore image and let me download so I would be able to restore my system?

I was trying to find recovery system from website but I can not find any restoration files or image.

I need image of system.

Thank you

It's just the radio that doesn't work, all other sound is fine... You can hear static if you push the volume as loud as possible. Sounds more like am static than fm static. Don't think the RCA outputs would make a different, but who knows?

I'm still wondering why some guys have three radio options in the factory settings, and why I only have two. I reloaded the software from the OP, but still only have two.

If anyone has the time, can you post a screen shot of your radio options?

Video on youtube 6 sec:

Please find file name above on youtube. I can't place direct link before I have posted 10 messagers.

When I turn on first or rear gear the device switches off for a quarter of second: screen goes dark; lost GPS signal. And it happens in the other modes: radio/music player does not sound for a half of second.

The original factory installed unit had worked well.

So I am asking if it can be fixed or the item is faulty?

Maybe it is important that front and rear parking sensors are factory installed. But there is no any connection between parking illumination and the technical problem with the unit.

It only appears shortly after first or rear gear is turned on.
