Help needed

Hi lads, Just installed my unit yesterday and I'm experiencing some problems which i hope can be sorted. Ive got the 4.2 1.6ghz dual core unit

First off the guy that installed it said I will need to bring the car back as the aerial needs repairing so I don't have the radio working yet

-The LED lights on the unit will not stay on, they will power on when using the "element settings" but will not stay on

-When ever I'm using any source to listen to music or video, via usb or wifi tethering the music drops, and cuts out completely for a second every 35 45 seconds. Its pretty annoying to say the least

Any ideas? haven't had much luck finding these issues on the forum I'm hoping someone knows how to fix

cheers

Never heared anything about issues like that. Have you tried to contact your seller? For me that sounds like an MCU problem.

Yo could also try to reflash fimrware. What MCU Version do you have? Please check under settings -> About Tablet -> Software Versions (similar)

Does your car have CAN Bus ?

Did the unit come with a CAN Bus decoder ?

Has anyone else experience the install issue I keep having?

After a while the system just wont allow apk files to install. It will bring up the install screen, but if you tap the install button iits like you aren't even touching the screen, cancel works bit install doesn't. This has happened go me now 3 times and the only solution is to factory reset :(

Malaysk rom 3G dongle problem and APN

Good morning everyone,

I just installed the version of KLD RK3066 Malaysk 4.4.4 KK

I have a big problem with the key data.

Practically the indicator is blinking blue, but the connection failed.

Previously I had the version 4.4.4 of Coudu and key data work, also with the original version 4.2.2 worked.

The page of APN is blank. I tried to enter the APN Vodafone, I press SAVE, but did not create any new APN.

I'm so sorry because of this FirmWare Malaysk is super and really well.

Anyone can help me? Thank you

Please guide me to a kitkat rom that may work on mstarcedric3 mst786 1din unit, without MCU because I can't identify it. Also I have no usb port for adb purposes only media otg one. Resolution is 1024x600....Since I have no need for mcu upgrade for now, what twrp img I should flash? Thank you!
[MTCB Android Head Units Q&A] agentdr8:
That device isn't the same as the ones discussed in this thread/sub-forum, so it's unlikely any of the software here would be useful to you.
[MTCB Android Head Units Q&A] katalinscrob:
Ok, I anticipated somehow this useful reply :)

At least could you tell me if twrp .img for your units is ok to flash via terminal emulator "dd if of" ( since I have no usb port to connect to via adb commands)? Thanks.
[MTCB Android Head Units Q&A] agentdr8:
I think it can be installed using dd, but on these rk units, we have a utility named flash_image, which can flash TWRP.

Also, unless you've got a version of TWRP designed for your headunit, I doubt the one for these would work.

DAB

Hi all, I have just bought a pumpkin klyde 4.4 headunit. Also it came with a shinwa (?) DAB module for it, however anyone who also has one will testify, the stock DAB app on the headunit is crap! Does anyone know if there is a newer updated APK for the DAB app out there please?

The CAN bus has nothing to do with your GPS.

A CAN bus is a controller area network bus. It is a vehicle bus designed to allow microcontrollers and devices to communicate with each other without a host computer.

You do not need a CAN-bus decoder box. However, having one allows your HU to interact with your car. Depending on your model those interactions will vary. In some cars your need a CAN bus decoder in order for your steering wheel controls to work; in others you don't. Some cars have a factory amp that gets turned on through CAN bus commands. If you have a CAN bus controlled Amp you will need a CAN bus decoder. Keeping the radio on and playing after the car is turned off but turns off after a door opens is a CAN bus command.
[MTCB Android Head Units Q&A] ddbigs:
Thanks. The seller said I don't need it for steering wheel control. I hope he's right. Ordered from Aliexpress DHCOO.

How would I know if I need it? My stereo doesn't stay on after the car is off. My stereo is very basic, no screen. Its a base model Altima.
[MTCB Android Head Units Q&A] superbass311:
You don't you will have 2 wires on the back called key 1 and key 2 (I think brown) find your steering wheel control plug. It will be small in the back of the radio. Splice into the 2 or cut the connector.

[MTCB Android Head Units Q&A] tmiller101:
My hu has two wires labeled key1 and key2 they are for swc. If you have these two wires going to your radio then there is a good chance you may not need a decoder. However a quick Google search for your make and model will give you a better idea on how your car communicates with your radio

Car Joying website has a blog on how to setup swc without a decoder box..
[MTCB Android Head Units Q&A] superbass311:
That's how it worked in my brothers toyota camry. Key one and key two worked for his steering wheel controls. He has the JBL stock system and the wire harness had an amp turn on box. Simple wire harness from Walmart.

If he wants his car to display which door is open and stuff he would need a decoder but for steering wheel controls no.

Hello fellas, I need help!

Got a Problem with a Pumpkin KD-C0357, rk3188, KLD stock rom. Installed in a VW via Canbus adaptor. Strange thing: everything works fine except the keys led. They do not shut down while the HU does. They're illuminated all the time. Cancelling 'key led' Factory settings didn't work for my device. Illumi cable is connected to acc cable.

I'm confused. Is it a firmware issue?
[MTCB Android Head Units Q&A] themissionimpossible:
VWs usually have ACC and +12VDC cables position exchanged at the black power connector.

Hello help please I'm trying to set up my CanBus system in my 2006 Dodge Charger but I do see a settings for any dodge systems can someone tell me whats a sub for dodge in the application
[MTCB Android Head Units Q&A] illmatik:
I had a shop install an Eonon GA5166F to replace my Audioid unit that crapped out on me.

The shop had some initial problems with the Canbus, as turning on my headlights was triggering the reverse camera. The shop eventually figured it out and got my steering wheel controls to work good.

I still have two problems I'm trying to figure out:

- No illumination on my buttons. They turn on for a second when the unit powers on, and then they go off. As I understand this is controlled by Canbus, but turning on my headlights doesn't help either.

- I can't choose my favorite AM radio station. The station is 680, and with the knob I can only get 678 and 685. Real frustrating. Other stations seem to come in very clear so I don't think it's a reception problem. How do I force the radio to play the station number I want? Once I can set it as a favorite or something I'm good to go.
[MTCB Android Head Units Q&A] superbass311:
You need to go into factory settings code 126 and change your radio region for your radio and your lights is your illumination wire on your wire harness not your canbus. You can leave the lights always on under key light in factory settings
[MTCB Android Head Units Q&A] illmatik:

Man you are the greatest. Works flawlessly and the root is persistent too.

Just type the *#hct#root# in the factory settings password and you have persisent root.

How easy can it be. I remember spending a whole afternoon rooting my moto-g. This is the easiest root ever.

I just replaced the default music app with root explorer!

In your device go to settings -> scroll all the way down to Developer options -> in Developer options find USB debugging and hit the checkbox ----> now USB debugging is enabled and your device should be able to communicate via usb with your headunit!

Hey guys,

I'm running an KLD-Device 8Erisin 2698V) and got some issues after flashing Malayks rom:

The original Software (quite messy) was able to support all HW-buttons (like "Loud", DVD and so on). After flashing Malayk's Rom, just the Buttons "Menu", "Settings", Volume-Knob , "Search-Knob", EQ and "Play/Pause" are working (all on the left panel-side -> see attachment).

I wanted to remap the buttons using MTC-keys but even with Car Service, I cannot figure out, which Key-Code these buttons have. When I press them, the Device gets no signal.

Has anyone got a similar or the same issue and solved it? I already tried to choose another "Keymapping" in Factory Settings but with no setting I got any change.

Hope you can help me.

Hi guys. I've an unit based on RK3066 on my Opel/Vauxhall Astra J, it's "well integrated" into dashboard (It replaces the original 7" screen and doesn't change the dashboard and all buttons and controls of original radio) but I cannot configure correctly steering wheel button and some other button on original stereo. I've installed "RK3066 HeadUnit" and "CarService" but works fine only volume, skip track and mute command. I cannot configure and remap phone command to hang up a call, and so on... Any idea?
[MTCB Android Head Units Q&A] ojuniour:
Unfortunately, I haven't.. And I contacted the company directed.. They told me all their brands are like that.. It is really stupid. I mean comon, it's 2015!..

I am sorta came up with a brilliant but geeky-ish solution. I bought a nano wifi router. (Example Hootoo TriMate) just go on amazon and there are alot.. I plug the mini router to myc ar (because it uses a micro usb to ush just like phones). SO waht these nano router does is that you can hotspot wiht your phone, and the router connects to the phone AND then rebroadcast its own wireless signal in which other wireless devices can connect under one subnet.

THen from there you can get any mini android cast boxes like chromecast or even raspberry pi...

You get an hmdi-RCA cables, split it, and plug one into the car radio input, and the other split into the headrest.

Then you can get any signal form your chromecast or whatever android device you are suing all around.

You can then connect your android car radio wifi to the router and control the android box wirelessly...

The setup might look complicated but it is really easy . That's the best I can come up with..until there are alternative methos..

Final thought is these radios suck. My Wi-Fi is broke 50% of the time and I have to restart the unit to get it to work. Sometimes the system wont even load the home screen but the radio is playing in the background. My 1st unit had a Bluetooth issue with music being distorted so I sent it back. This one is fine but all other issues remain. I tried to root 1st one but bricked it. Td730a. I tried an21 method but failed or flashed incorrect file. I can get temp root via kingoroot but once I restart it goes away. What can I flash to this model and how?

Hey,

I bought the same radio. a fine and wonderful radio with many options.

I am happy with it.

Still i need a little help with it:

1. I have three USBs.

One, the loose cable, I use to connect with my samsung phone.

One, on the 2 usb's on one conector, I use for a hard disk

and the other does nothing when the first is conected.

Is this normal or is it a software setting.

2. Where i find the pasword for the factorysettings?

3 Where can i find what type of radio I have the RK3188 or RK3066

4 I want to conect a bluetooth keyboard bud it wont conect i have tried 2 kinds.

5 my old phone is still in the bluetooth list how can i disable that

Has anyone been able to get the easy connected app to work. The old mirror link app worked fine before this new one. Would it be possible to get a link to download it or something?

Update: figured it out, I had to reflash a few older roms to get the old one and use that license from that one to apply it to the newer version. For some reason the newer version wouldn't download a license.
[MTCB Android Head Units Q&A] Charm1418:
1. Seems like this is normal as the radios normally only come with 2 USB ports. So it probably switches between them. You can use a USB hub if you need, though it would best to use a powered hub.

2. HuiFei wiki page . Try "126"

3. Settings>About>CPU ; The RK3066 is a dual core, the RK3188 is a quad core.

4. May mean the bluetooth is only for phones and isn't visible by Android only the MCU. Try using a USB keyboard.

5. Don't know the model but try to press and hold and see if it shows an option to delete.

In the Factory Mode I choose the right transmitter unit and try all other units. But with no effect. Has anyone any idea why no sound come from the radio app? I think there is a problem with the communication between the radio transmitter unit and the Radio Unit.

In order to reset back to factory you have to press the reset button and restart the system. The location of the reset button differs, its gonna be really small probably need a paper clip to press it. Also install quick boot (need root). This will give you access to recovery mode.

Each model is different. Goto to the about setting in settings and it should tell you the RKxxx and MCU version.
