Has anyone found any LTE (VZW) usb modems that work? I was thinking about just getting the VZW ODB that has a hotspot built-in but would like to just use a usb one if possible. That wifi mod a few posts back is kinda like what I did on my KLD2... Except with mine I had a couple old RP-TNC 9db antennas for an old Linksys wrt54g that had broken hinges on them. The antannae are about 10 inches or so long. So I cracked the plastic housings off, soldered one wire to ea, covered ea in heat shrink tubing, then together, and tucked it in the top center of the dash.

Oh and I was thinking of wiring in the factory mic that Hyundai installs in the Sonata. Has anyone tackled that?

---------- Post added at 07:12 PM ---------- Previous post was at 07:07 PM ----------

I thought that already did... There is a mod in the MTC car service (I think...correct me if I am going wrong), if set, it will lower it on boot, but disable it and it won't.

Hello

Could anyone shed some light on the GPS issue I have listed above. I have tried Boos ROMs (JY &KLD) and they seem to work ok for GLONASS only but I lose access to 'Other' tab under Factory Settings (when I select it I get 'Unfortunately, Settings has stopped').

Thanks

Request

Hi everybody,

I have a car, the type is Opel Vectra C. I would like buy a headunit. I found a Joying unit.

Android 4.4.4 Kitkat OS Capacitive Touch screen on your Opel Vauxhall Corsa Vectra Antara Meriva Astra Vivaro Zafira

. CPU RK3188 1.6GHz Cortex A9 Quad Core

. RAM DDR3 1G, 16 GB memory

(sorry I can not send picture)

I have some questions:

1. The Joying like reseller is reliable?

2. Use it someone such headunit like this and what the experience?

Thank you!

Great. No one have the slightest idea about the multiple mystical brightness controls in Malaysk rom. I tried to dig into the Russian forum at no avail. I think theres no explanation even there. :confused:
[MTCB Android Head Units Q&A] Malaysk:

[MTCB Android Head Units Q&A] rricardouk:
Hi, for start, thanks for the great work done.

But, could we have an explanation of how the controls for brightness -Auto/Auto Intelligent/Dark actually work? Because some people - me included- dont have any consistent results. All the options just dim the screen and override what we set manually.

Again, thanks alot for your tremendous work on this roms. Cheers.

Joying reliability

I have two Joying RK3188 units and have found them to be very reliable. Here in Florida the temperature is often 35C so head-units inside car's get very hot in the sun. I had an Eonon branded Klyde head-unit before and it failed after about 6 months. I replaced it with a Joying unit and it's about a year now with no problems. I liked it so much I bought a second unit for my wife's car, and just bought another to put into my son's car.

Their main support contact (Rambo is at support@carjoying.com) is very helpful and usually answers questions quickly. One of my units is running Malaysk's July ROM and the other unit is still the standard Joying ROM with MCU at 2.55 - my wife is happy, so I don't touch that one :)

A satisfied Joying customer,

Graham

Look at the launcher and radio widgets, this is a HuiFei, the thread does give the info needed to distinguish between units if you search :)

edit : actually, I was just looking through the pictures and spotted something (see below attachment)

Its says "GS" after MTCB, HuiFei/KGL should have "KGL", RoadMaster should have "RM" and Klyde "KLY", so potentially youve spotted a new manufacturer, or possibly it was just a development version ? Only one way to find out - buy it !

What headunit have you got ?

I was under the impression that HSDPA/HSUPA/HSPA were all 3G

I m sure someone added a mic using the wires from the original built in mic - they removed it and soldered on the wires to an external mic and this sorted their problems, if its not in this thread, it may be in the AN21-U thread or even the AN21-U hardware thread, deffo seen it done somewhere though.

edit : I see agentdr8 says the same above, lol

How to know if you have a HuiFei/KGL, Klyde, or RoadMaster

Hi,

So far there are 3 headunits that are very similar but have no compatible firmware.

- HuiFei/KGL

- Klyde

- RoadMaster

edit: there is a potential new manufacturer (HotAudio) with firmware v1.81

- GS

link: http://www.ebay.co.uk/itm/251453910925?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

People are bricking their units because they do not know which unit they have, they see that the Radio apk is the same as they have and think that the firmware of HuifFei will be compatible. But firmwares are not compatible because MCUs are different and incompatible.

How to know which unit do I have, and what firmware I have to use ?

typos1 made a huge effort and collected info on the different units. I have put the info together (see attachment). I have also added the info of the firmware that you have to use with each unit.

So far only HuiFei firmware is available on the repository, but I will upload the firmware for Klyde and for RoadMaster too. Be patient.​

Please share your experience:

I would appreciate that you share the problems that you have had with the firmwares.

So I created a google docs for you to fill.

Please add:

- nickname

- unit you have (HuiFei/KGL, Klyde, or RoadMaster) (use pdf attached to know which one you have)

- firmware that you installed

- problems

- how you solved it

Thank you for your help.

It's strange to have an issue only with bluetooth. I use this app to test the mic :

https://play.google.com/store/apps/details?id=com.ad960009.app.MicToSpeaker

And I hear my voice clearly when extrenal mic is plugged. But no sound with bluetooth call...
[MTCB Android Head Units Q&A] darkleo2000:
Hi Guys.....

mcu.img file was successfully decrypted by me.

What i can see inside?

Its full code of MCU which can be disassembled in IDA

Also i decrypted files from Klyde.... KGL and RM unit... they all have the same code with small differences

For example:

KGL code sample:

dvd dtv radio playpause loud prev next answer hangup mute eq mode bt tune+ tune- gps home menu vol- vol+ bluetooth canbus ipod beep backlight language color led led_type key0 model sn password customer logo1 logo2 key key_w1 key_w2 stw_1 stw_2 ir MTC%s-%s%s-V1.86 B KGL Jun 19 2014 09:29:05 126 S07 00000000

RM code sample:

dvd dtv radio playpause loud prev next answer hangup mute eq mode bt tune+ tune- gps home menu vol- vol+ bluetooth canbus ipod beep backlight language color led led_type key0 model sn password customer logo1 logo2 key key_w1 key_w2 stw_1 stw_2 ir MTC%s-%s%s-V1.85 B RM1 Jun 09 2014 10:00:41 126 S07 00000000 mtc

Klyde code example:

dvd dtv radio playpause loud prev next answer hangup mute eq mode bt tune+ tune- gps home menu vol- vol+ bluetooth canbus ipod beep backlight language color led led_type key0 model sn password customer logo1 logo2 key key_w1 key_w2 stw_1 stw_2 ir MTC%s-%s%s-V1.86 B KLD Jun 23 2014 09:47:38 126 S07 00000000 mtc

As you can see simple text strings inside decrypted mcu file are the same.... just small differences in base system KGL/RM1/KLD which mean base system as Kai Gei Lee Klyde or RoadMaster

All files are based on Intel 8051 architecture.

Now main question....

Why in KGL MCU named MicronTek if chip named IAP15F61S2 from STC China company which have website on www stcmcu com ?

Which name of MCU in Klyde?

Which name of MCU in RM ?

I want to know names for compare the code of MCU...

Great work !!

Good to hear they are so similar.

Dark Alex said it was a MicronTek chip, he was the source of that info, dont where he got it from.

You seem to be saying that he is wrong and that it is an STC China company/stcmcu MCU chip ?

If thats right let us know (do you have a photo?) and we will get the wiki updated.

The RoadMaster has an NXP Semiconducters chip, we dont know the Klyde's chip. Maybe you can see the name from the pics of the Klyde internals a few weeks back (or maybe pm the person who posted those pics?).

We know least about the HuiFei's internals now.

Yes, there is a thread for it, its a WD8801.

I also found this unit from the same seller as my original post. It uses some of the same feature screenshots, including the MTCB-GS one. It has a smaller screen, but has a volume and tuner knob, as well as the front USB port. And it looks almost exactly like the factory stereo!

I have been looking at this unit:

aliexpress.com/item/Android-4-0-Car-DVD-GPS-Navi-Car-PC-3G-for-Toyota-Kia-Nissan-Tiida-Qashqai/1187811681.html

I believe its a KGL from the looks of it. The only thing that bothers me is the lack of a cooling fan (maybe not an issue) and the fact that its on aliexpress (I have never bought anything here and not to familiar with it).

I also found this one on ebay that has a cooling fan but Im not sure if its upgradeable etc:

ebay.com/itm/191227453040?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

However, it doesnt mention being able to change the backlight color, which is kinda cool, or having miralink/airplay/ or whatever you want to call it.

Just looking for a little guidance. Also, if this is the best price available. Thanks in advance!

Hi guys, I have a quick question.

If I try latest Malaysk's RK3188 800x600 rom, the radio works but the FM auto tune part does not work. It is press search (or tune to previous/next) it just searches the entire spectrum and doesn't find a thing; but if i set the frequency manually, it plays the station fine.

If I try stock Klyde rom (conquer); the search works fine. I like Malaysk's rom a lot. I even tried replacing the KLD MTC apps (including radio app) in Malaysk's rom as Malaysk suggests in one of his posts. That didn't help either. The radio style goes back to KLD but search still does not work. Is there anything else I have to copy from KLD rom to Malaysk's rom to make this work?
[MTCB Android Head Units Q&A] agentdr8:
In the beginning, there were none. Some headunits had a hard DIMM button to cycle through some presets, but there was no automatic dimming of any sort. Now there are many. Having choices is a good thing.

Today, my steering wheel controls for volume up/down and next/previous stopped working, and i don't know why.

Yesterday, it was working at some points, then would randomly stop working. No buttons pressed or anything that would disable the function.

I also have the media keys enabled as well, with still no avail. Sometimes, i would open the MTU Service and see that the media key would be disabled for no reason.

[MTCB Android Head Units Q&A] MCL1981:
I suggest you all try out the app Lux Dash for brightness control. Since there is no light sensor, and the built in brightness control is useless, Lux solves all the problems. You can setup profiles for day and night. Then it will automatically switch between day and night mode based on automatic sunset and sunrise time. It can "sub zero" dim as well, which means it can dim below the normal zero point. Zero is not very dim on these, so it can make it even dimmer for you.

I have mine set to go to 100% between sunrise and sunset. The at night (sunset to sunrise), it dims down to negative 60%. I also have it lower the color temperature of the display to make it a little less harsh.

It works flawlessly.
[MTCB Android Head Units Q&A] pants001:
Ive tried several auto dimming apps and have come to the conclusion that they either dont work or dont give me manual control for times when the weather is quite dark

Ive been using this for last 6 months and simply have an icon on my main screen.

If i decide its too bright, just hit the button....easy.....I much prefer being in control of the dimming.

Hi all,

I recently decided to purchase this Joying head unit and fitted it in last night.

Still new to this but I tried change my boot screen and I can't seem to do it

I got into the settings menu with the password listed 126, I then went to change the boot screen then press apply(maybe save) then exit which then rebooted the unit but the boot screen doesn't change.

Is this a known issue or have I done something wrong?

Also is it possible to adjust the line out output gains? I find the volume isn't loud enough compared to the factory head unit I repaced

[MTCB Android Head Units Q&A] typos1:
They are reliable for most people, but occasionally there are problems, it seems youve been unlucky.

Yesh, just plug your phone in via the usb port.

People have mentioned this on the BMW units quite a few times and the solution was to use the older 1.86 MCU.

I think they use the electric motor as a generator.

Your post sounds like an advertorial !! Glad your happy though. BTW you do not have Joying units, they are just resellers, you have "Joyous" units.

Updates are on the fileserver (see first page or my signature) or theres Malaysk's ROMs (see has signature).

Read the first page and search the thread, theres plenty about mic mods.

No, you have to buy a hi-lo converter and use the speaker outs or a get a pre-amp or line driver.

Thanks jrgalang for the response. I have tried literally all of the settings under Factory Settings. My understanding is that factory settings is associated with the MCU.
