My radio apk is storing station names correctly now, just not mixing GPS sounds correctly. I have GPS mixing ratio set to 4 yet it doesn't effect the GPS overlay in the radio apk at all, but does in the music apk. Makes me think there is a glitch in the radio apk that's gone unnoticed.
[MTCB Android Head Units Q&A] NYCAR:
But you are only showing the result, not the how-to that leads up to it. I already agree that it works for some people on some devices. Please tell/show all the steps that get you there so I can verify that I have done all I can to try to make it work with my phone on my head unit.

EDIT: given that Joying's site has an upgraded version of my head unit that specifically mentions being able to mirror with Android, but my older version has no explicit statement, I'm going to guess I'm out of luck. But I'll try what I can.

How do I actually install Easy Connect? I read the first post, but I still don't understand.

so I tried again with easy connect 2 different android phones

samsung Galaxy S4 android 4.4.4

Samsung galaxy s5 Android 5.0

the Galaxy S4 connects to the Head unit and I can even see the videos that exist on my phone but can not play them, when I try to connect and use the screen mirroring part it says initializing for the first time and it takes a while, the Car mode app starts on my phone but I end up with a blank screen on the head unit and when I try to exit the app crashes.

On Galaxy S5 I can not connect at all

tried uninstall and reinstall the easy connect, restart phones,

tried airplane mode on on the head unit and on the phone

unfortunately this awesome app does not want to play nice with me JY dual core could be the ROM I am running on the hEad unit?

Next week, I think.

MCU KLD 2.49 and update_4_4_4_800X480_RK3066_19_MAL_NEXT_LAUNCHER_11_05_2015 It works perfectly for me. :)

Tomorrow I will try MCU 2.54
[MTCB Android Head Units Q&A] tws4834:
I just did this on my new KLD install.

I connected the transmitter's power to reverse light power, and grounded it on the body close to the camera. Then I connected the transmitter power output to the camera, and the camera's video output to the transmitter's video input. This way, the transmitter and camera both power on when I put the car in reverse.

Then I hooked the wireless receiver's power to keyed aux power, grounded it on the frame, and plugged the receiver's output into the (in my case) RCA cable labeled "CAM IN".

The receiver will be on whenever the key is on in this configuration. You *could* take the time to find your reverse light fuse and tap into it so that both receiver and transmitter come on when you shift into reverse. I didn't.

For what it's worth, the wireless setup may not be worth it unless you have a really long car or are running it out to a trailer or something. I find that the video is laggy and choppy at times. Sometimes it's perfect, but not always. I may just break down and run the cable.

mcu help

I have tried a few different mcu versions, but I am running into issues with the iPod and Music settings. I listen to audio books, so I want the book to start where I left off, the next time I get into the car. It seems like all the mcu files I have used tried to update either restart the book from the beginning or restart the same folder each time. Is there a setting I am missing?

Thanks
[MTCB Android Head Units Q&A] Alphas:
JY unit are never rooted, in fact they told me it cannot be rooted. But just reflash the firmware and you have a rooted unit.

Never change the MCU unless it is already broken. You have to find the original MCU and flash it back. Flashing the wrong mcu is likely to brick the unit.

[MTCB Android Head Units Q&A] madjeff:
I have the same unit (It's a Joyous Unit) and I am running the latest ROM from Malaysk, but Couda's rooted rom works as well. You need to grab the rom and drop it on the GPS card then reboot, and the system will do the rest. You can use the KDL, KGL, or JY firmware, but I would grab the JY-based one to start.

I recommend grabbing the latest JY-based MCU as well (v2.49 is the latest) as it fixed a few issues I had with the original MCU that came on the unit.

You can find everything you need on the first post in this thread.

I get Erisin ES9501A, and all become bad things and bad experience. KGL, RK3066, 1024x600, issuies :

-Unit not complety fit on W211. (Must to cut a bit of 2 plastic piece to the radio come in line with the rest of the car).

-LEDS are RGB, and I think they not have the color of the rest of the leds from the car.

-Can-bus not work or work bad untill now. Wheel controls can not be detect, can't be learned too. From canbus it is conected, I can not open the tray under the radio. Sometimes car configuration are change, like external mirror automatic close when I close the car. The unit arrive to me with MTCB-KGL5-V2.22 and Android 4.4.4_15012015.

Last night I finish to try all other MCU firmware version, but noone works. from v2.47 KGL, KGL1, 2, 3,4 and 5. I try also "MTCB-LZM1-V2.08" same...

I have one question, Headunit, how calculate the speakers levers, by the built-in microphone? or reading speed on can bus? becasue Headunit always make his work of set up the volume level...

If the unit detect when I put the brake or the reverse, where it is reading? can bus?

When the radio it is loading, I can read in the dashboard Telephone - waiting, Audio - Waiting, and later just ----. What these mean?

Thanks, you say there is a "quadcore MCU" - there is no such thing as a quadcore MCU, the MCUs are the same for dual and qaudcore versions. Where is the MCU file ? - You have not listed it.

No units are rooted from the factory ! Just reflashing the firmware WILL NOT root a unit, you have to flash a rooted ROM for root !

You can change the MCU WHENEVER you like, it will not brick your unit even if you flash one from a different manufacturer, it will jsut mess things up, reflashing the correct MCU from the correct manufacturer will restore thngs.

You can use any MCU as long as it is an MCU from the manufacturer of your unit and if you have a numbered MCU (KGL1 for instance) as long as it is the same number (KGL1 MCUs have to be updated with a KGL1 MCU)

DSA does the rooted ROMs, I think we have established that you can only use the app you want on quadcore units, you have a dualcore unit.

Give him a chance, they have only just been uploaded ! I dont think DSA sits at his pc all day reading this thread, I think he does actually have a life as well !

You are wasting your time - buy a quadcore unit !!

The mcu is in the link that joying uploaded. And why are you saying that mcu can be uploaded to other units. Stick to the golden rule don't fix unless it is broken. Mcu could potentially brick it especially across other units. So that DSA could see the link and uploaded it to the server.

Are you stating that Easy Connect will not work on a dual core unit?

That would be a shame, since I selected my Pumpkin head unit because it was the only one they had with a layout I like, but was available only in dual core. But NOW I see that Joying has a quad core version for only $30 more.

Oh well.

Anyway, for people who are as ignorant as me and stumble onto this post, here is the moron's guide on how to install Easy Connect (or other apk).

1. Download Easy Connect APK from the link in post 12459 (most current as of this date)

May require a DropBox Account

2. Place file on USB drive

3. Connect SUB drive to head unit

4. Use APK Installer (in the non-car portion of the head unit) to find and run/install file

5. Run Easy Connect app that now has a shortcut on the main screen

6. Connect phone via USB

7. Unlock phone to get Programmer Access following on screen instructions

8. Enable USB Debugging on phone

9. Allow phone to register – Requires internet.

Sadly, my phone failed and I received this message;

Registeration (sic) Failed

Cause:Your phone is not authorized for registration. Please contact your vendor.

The registration is necessary, but it is made from the HU and not from the phone.

[MTCB Android Head Units Q&A] NYCAR:
I understand that is an option, and probably nothing bad would happen to my phone if I did it. But I just cannot bring myself to do it. Thanks to my grandfathered plan, I do not get upgrades and would have to pay for another new phone in full if something happened. And I worry about losing my grandfathered plan by doing so.

The car had wifi access at the time, but I'll try again to be certain. The warning lead me to believe that phone itself is the problem. As an aside, I saw nowhere on my phone to tell it to always allow the head unit to do USB Debugging. I could turn debugging on, but had no way to allow a specific device.
[MTCB Android Head Units Q&A] doctorman:
well you paid 78$ same as 80$

and for you it was worth it since you were looking to pay for dual core SoM so a bit more for quad is worth it.

I can not upgrade now after I got my unit ... unless I can sell my original dual core SoM to make the money back

as for that link .. it is an upgrade from memory not for dual to quad core.

I wonder how much of speed gain you get with a quad core at boot

now it takes me 35sec before I see the screen and 1:05 min to be fully loaded with dual core on JY firmware

you are using the wifi on the HU to connect to the iphone wifi so you wont have internet
