[MTCB Android Head Units Q&A] Ch1337:
Hi everyone!

I have a couple of questions:

1. - Bluetooth, radio, static.

I just got my HuiFei GS 4.4.4 HU rooted today.

Everything have been working fine, until something wierd happened.

When I start the bluetooth app, the HU starts making a white noise. When I close the BT, it disapepars. radio sound works fine. (I have to close it, not just go to homescreen=

When I connect my phone via BT, the static noise is still there. The BT sound is REALLY low, but if I close BT on HU, and start radio, the sodun is fine again.

The wierdes part is when not playing a song from my phone/BT device, the BT picks up signals from the radio, so theres a VERY low sound from the radio. The songs from phone and radio play at the same time.

EDIT:

I just backed up from revocery, and it seems to be OK now, actually. My volume panel goes from 1-30, and when it reaches 28-30, the white noise is there, but I'm kinda guessing it's normal when that high.

Does anyone know why this happened...? It can't be hardware related, being the radio works just fine.

2. - Element (LED Colors) buttons not holding light

My radio has only blue LED-buttons, but with the root (And ROM) I can go to settins > Elements, and change the button color. The change of colors works fine, but it holds the color for just 2-3 seconds. So the colors work, but it's not static. The settings seems to be "saved", because the color I chose is still there after I exit settings and go back to Element settings.

Anyone know how to get the colors to hold? The RGB-LED settings are ticked ON in factory settings too.

3. - Canbus or not?

I have a VW Passat 2002 B5 (3BG) stationwagon, and wonder if this has Canbus. I can choose which Canbus I want to use in factory settings, but I don'w know which to use (Currently selected is "VW&SKODA(Simple)".

How can I use canbus, and know IF I have canbus?

I've pretty much got things the way that I like them. I'm pretty happy with Malaysk's roms. I have some questions though:

Is it possible to get an external USB wifi going on one of these? I have 2 usb ports and not much to do with them.

Whenever I start it goes immediately to Bluetooth. Is there a way to prevent this?

Any chance we can get the time in the status bar?
[MTCB Android Head Units Q&A] xrapidx:
Not sure what you mean by external usb wifi?

You can already set the device up as a wifi hot spot - or connect to a external wifi network?

thanx for the torrent links :good:
[MTCB Android Head Units Q&A] kalle99:
2. Try to go to factory settings, password 126. There is a setting just beside RGB-LED that says KEY-LIGHT. Tick that box if possible and light will stay.

Cheers
[MTCB Android Head Units Q&A] cocchiararo:
Any chance the "dimmer" service/setting might be weird?

I am new to your ROM, so i might be doing something wrong.

I installed it, enabled xposed and the module, rebooted, enabled the service, and set the "start" time to "18:20" and the "end" time to "08:00".

Yesterday, it was past the start time when i enabled it ,and it never dimmed, So i did it manually. Today, it was past the end time, and brightness remained where i manually set it before leaving my car.
[MTCB Android Head Units Q&A] Ch1337:
Thanks for reply! I tried ticking the Key Light and rebooted, but it just didn't do it for me :( same as earlier, it just goes back to blue after a couple of seconds :/

EDIT : Took a video of it, perhaps it can enlighten the problem..?

Hi

Just two questions :

Is ther a MTCRadio with a Real RDS AF Working ?

Is ther a MTCMusic who save the last music played ( and don't hangs the Bluetooth ) ?

Thanks

I to like the stock launcher but is there a way to change the weather widget to display farenheit?
[MTCB Android Head Units Q&A] cocchiararo:
at least in the JY one, you click the weather, a new window/activity appears, and you can click the C F button to switch.

ps: is the stock music app unable to shuffle? i can only find a repeat button T_T
[MTCB Android Head Units Q&A] kruuth:
Sorry not sure I follow you about reading the main message. I did. I went and tried the clock thing and it didn't work.

What about USB wifi?
[MTCB Android Head Units Q&A] honzicek:
The radio doesnt remember time.

After I turn off my radio the colck reset and dont show actual time but time off turning off. Is it power related. It is KYD in FORD Focus.
[MTCB Android Head Units Q&A] Blankstar85:
Did you check your power and ignition cables?
[MTCB Android Head Units Q&A] typos1:
Ah, yes I hadnt thought of then both being on the same control.
[MTCB Android Head Units Q&A] sickbro80:
Hey guys, just wanted to say huge thanks for all the info provided. I just got mine yesterday off ebay, paid $350 shipped to the US. I started my install and had a few questions someone might be able to answer.

Is there no amp turn on wire anywhere? I didn't see one labeled as such, so I ran it into the acc, but I wasn't sure if I missed something.

Also I didn't see a wire for a powered antenna, I ran that to the account power as well. It all seems to be working, but its probably not exactly "best practice".

In addition to that, on my drive in to work today, my battery light started turning on, when I turned the radio off it turned off too. I've been suspecting an alternator issue for a while, and I think this might have just pushed it over the edge.

Last question, and this could answer some of the first two, but what are the following wires for? The antenna wire I though might be for a TV antenna, instead of an FM powered antenna.

K1 - brown wire

SAF - pink wire

Ant - blue wire off rca harness.

Thanks for the help.
[MTCB Android Head Units Q&A] typos1:
Blue/ant could be used for amp or antenna I think, its deffo for radio ant, though, not tv, either way it has power when head unit is on.

Pink, I m sure I have seen pink before on car stereos, cant remember what its for, a quick google shows it being 12v permanent for Jeep vehicles.

( http://www.carstereo.com/help/carwires.cfm )

Brown, dont know.
[MTCB Android Head Units Q&A] agentdr8:
IIRC, K1 and K2 are steering wheel control wires, along with the (smaller gauge) black ground. There should be a solid blue wire in the main radio harness, that can be used for both amp turn-on and power antenna. I don't recall connecting any of the wires that were in the RCA harness, other than the reverse camera input RCA.

I think the pink wire you're referring to is for parking brake ground, so that it won't show video unless your ebrake is on. I didn't connect it.
[MTCB Android Head Units Q&A] pakidermo5000:
There's a dump of the 1.72 image in the wikipage. You may try using it. But, again this is for HuiFei not sure it will work in your unit.
[MTCB Android Head Units Q&A] sickbro80:
Thanks for the advice, I'll grab my multimeter and check out some of the other connections. On mine, the backup camera rca is on the main harness. Its the only one on there.

I haven't tried to tackle steering wheel controls yet. My car is a 2001 maxima. It uses varied resistance to determine button presses. I have no idea how that ends up working with this, if at all.

I took a picture of the wireing legend on top of my radio before I put it in. I've attached it here in case it helps someone else out. Maybe I'll type it out and try and get a good description with each wire, as some are a little less than obvious.

Thanks again for the help.
[MTCB Android Head Units Q&A] R4D3N:
Yes you can. That's how I did it ;)
[MTCB Android Head Units Q&A] agentdr8:
That's really different from my unit's wiring. I guess the blue on the rca harness is your amp/antenna. Your swc sounds like the ones on my Z, so you just need to find the 3 wires on the vehicle side; 2 go to K1 and K2 (the wires for the buttons/controls; doesn't matter which to which), and the 3rd for the ground (Pin2 on your pic; must use the ground in that harness to create the loop). It took me a while to figure it out, but everything works great.
[MTCB Android Head Units Q&A] sickbro80:
Wow, sounds pretty straight forward for the SWC. I'll play around with that tonight.

Thanks
[MTCB Android Head Units Q&A] dark alex:
Wow! I also installed the 1.86 update to my unit and I am very positively surprised! unfortunately had to stop testing for now. will continue tomorrow (my time).

For now my results are:

WiFi drop issue gone

Boots quickly (but its a clean install)

Bluetooth Menu is now there (Hint: First change PIn, then name. Else your name is set to the pin?!?)

RADIO IS NOW WORKING MUCH BETTER FOR ME It's like if they replaced a stone age radio module with a top tech one :D

iPod-App behaves different than before. Probably now it will work? Will check that tomorrow...

//Edit:

Oh! And I uploaded the image to my FTP. Thanks for sharing, xrapidx!

So the uupdate didn't resolve the GPS mixing volume I have with the radio apk and GPS, even tried sygic so see if it was an Igo issue, nope still same issue, the mixing volume isn't increased as per the settings in the GPS mixing settings. Nobody else notices this?
[MTCB Android Head Units Q&A] Gaslight0:
Tried to use TORQUE (Purchased) tonight for the first time after upgrading to 1.86 and it will not install. Gets an error code -24. So I tried the pirated version that came with the unit and it will not install either. Anyone else having this problem with 1.86?

Does anybody managed to make the gala function to work?

[MTCB Android Head Units Q&A] dark alex:
Well I cant tell on the sound quality in detail yet as I was trying with deactivated AMPs. Only hearing the center speaker which is wired directly.

But I did not even have a good signal befor. I only received about two or three stations and those were terrible.

Now I get a dozen stations or even more in acceptable signal quality.

I will rpeort back after driving a round today.

[MENTION=4618625]Sengir[/MENTION] do you mean my SDVC/GALA App?

Will report later but should still work.

http://huifei.fs-fileserver.de/content/release/SDVC_GALA/

What I lost is the possibility to remap the MENU-Key with xpposed additions... is not recognsed.

Also I can not use the GPS Button. When I push it nothing happens. Prrobably it only works with iGo...

cp TWRP_KGL-7650G /dev/TWRP_KGL-7650G , is this the folder with the img inside ?

I just got the TWRP_KGL-7650G.img from the first side.This way the command did not work.

Gave it a go with putting it inside a folder named the same way, and that did the trick.

>

/dev/flash_image recovery /dev/TWRP_KGL-7650G gave me this :

/dev/flash_image: not executable: magic 7F45

I checked freaktab, and someone had the same problem, and it worked with a different flash_image.

Any clues where to search for someting like this ?

I do have a KGL-76988G / KGL-8401G so i guess that is the problem ?

Hoped it works since it has the same rom....
[MTCB Android Head Units Q&A] 1-2-Hak:
My bad - the names for TWRP_KGL-7650G should have .img on the end ie TWRP_KGL-7650G.img so do it again using the actual image file.

It should work with any 800x480 Huifei unit. It is only named this as it was my model.

To save typing you could just rename the TWRP_KGL-7650G.img to twrp.img

Make sense?
[MTCB Android Head Units Q&A] 1-2-Hak:
BTW my last rooted_system didnt work. Have redone one that includes my RadioBlue

It is rooted manually by me so no Foreign root app issues.

I have also loaded xposed module framework.

Will put up once I build an update.img install and might change the pre boot.

I have also loaded all my stuff up to the FTP site at start of thread - This includes a working copy of flash_image in the firmware/twrp directory if yours is failing....

[MTCB Android Head Units Q&A] LostIn_Space:
Google now fix?

I have KLD radio with KK that is not rooted. I have had problems where "Google Now" would crash when I say the google now or even press the mic icon.

The other day I happened to be looked around in the secure settings app when I was bored and discovered at setting for google now.

Secure settings >> setting >> then check box for "Fix SystemUI Crashes (Googke Now)".

Note: I do have pro version but would image this option is in free version as well.

After checking the box my google now works!!!

I just need to fix my crappy internal mic now. People probably hear me outside the car yelling at google...

I hope this helpful to others. I googled it and searched the thread and could not find any other fixes for this since I did not want to cloud this already hard to follow thread.

video out

Hi, i have had one of these units for over a year now, and no real complaints so far.

However i have only just realised that the only output through the Aux leads is from the DVD player. is there any way to get output of the main screen, for when im viewing videos in the rear of my van?
[MTCB Android Head Units Q&A] agentdr8:
If you're referencing the dimmer in XposedMTC, then you need to make sure your timezone is configured correctly. I believe the default on Malaysk's roms is +3 (Moscow). I didn't have much luck with the auto timezone setting, and just manually picked my timezone.

Use the potato clock. Settings->System->Clock. Make sure you pick the option to make it visible. You can also adjust the location of the statusbar clock.

Hey [MENTION=3590033]Malaysk[/MENTION]!

Using the latest ROM on my 3066/800x480 unit and it's working great! Thank you for the nice work. :)

Question - what does the "Autostarts" setting do in the "System" settings? I can't really tell any difference in start-up whether an app is checked or not.

Also, what does the "Optimize the startup items" do? :)
[MTCB Android Head Units Q&A] agentdr8:
Has been asked many times before in this thread, so the answer should probably be posted to the OP. But that answer is no, unless you use some other trickery such as remote Kodi/XBMC and drive your rear screens with a Raspberry Pi or Arduino. That solution has also been discussed in this thread.
[MTCB Android Head Units Q&A] Siffion:
Cheers off to test this now
[MTCB Android Head Units Q&A] cocchiararo:
I was refering to XposedMTC, yes.

I have manually configured the timezone to -3, and manually set the start/end times.

Will look into those 2 things again, and the clock, today after work.
[MTCB Android Head Units Q&A] :
After changing the amp IC the unit has sound again. Moved from a TDA 7388 to a TDA7850. First impression: more volume on low setting, better balance as I have different speakers front and back. Instead of 100/35 f/r balance now 100/70 in the amplifier settings. Longer test pending...

[MTCB Android Head Units Q&A] 1-2-Hak:
[MENTION=3590033]Malaysk[/MENTION] I did some more testing with Rom and MTC on my KGL radio. My problem seems to be with the screen saving. If the screen goes off it doesnt come back on even after a reboot. The only way to get screen back on is reset and wait for the MCU to clear.

I have tried your rom with KGL 2.53 and the same thing happens when I click on the power button on the top right so its not the modified mcu that is the issue. It seems that the screen off in your rom upsets my unit at least. I have flashed an [MENTION=853627]coudu[/MENTION] Rom with the modified MCU and have no issues but would really like the option to change the shutdown time.

I will try your new ROM when it finally comes down and see if it has the same issue :)

It worked fine with my unit while it had stock ROM. (Eonon GA5151, basically a Klyde unit.) Never tried it with custom firmware, connected a 4G wifi dongle instead.
[MTCB Android Head Units Q&A] cocchiararo:
I think i did read it, but between both of us not speaking english as our primary language, and some other stuff, i might have missed many important points :P

I had set the clock, but the default color was not visible :P

I did some more testing/exploring of your ROM:

1) The XposedMTC function for dimming was actually working, the "issue" is that the brightness bar that is shown in the notification drawer is not synced with the one that appears when you press the brightness toggle. The one from the toggle follows the setting in XposedMTC, and is correct.

2) What are the "mtckeys" and "navitel" xposed modules for?

Most improved unit?

Hi Guys,

Thanks for all the great work on this thread especially the roms and mods. I initially had a KGL4 unit in my car and I managed to make it usable from the mods and knowledge in the thread.

Now I'm considering upgrading my unit, can anyone suggest which of these units is the most improved i.e without under-powered USB and WiFi dropout issues, mic issues etc.

Is there any way to use other equalizers than the one in Malaysk's ROM? I have the one that goes from -15 to +15 (9 or 10 bands), but when I put the lowest frequencies to -15, it still puts out a lot of bass :\ I had another 2 DIN radio unit (Beat 690 from beat.com), and it removed everything related to bass.

I dont have any amplifiers, just the 4x45 output from my head unit.

Radio Stations

Hi all,

I have a Joying 1024*600 dual core and a particularly frustrating problem is that the radio app keeps forgetting the stations every time the car is switched off. Running the latest stock Joying MCU (2.59) and stock Android build (9th of June.) I'm reasonably certain it isn't a power issue as I've just used an ISO connector from my Subaru loom to the head deck's ISO connector so hopefully I haven't joined them together incorrectly somehow. It finds the stations fine and reception isn't an issue. Is this a known fault or specific to me? Searched the thread and couldn't find anything relating to this.

Thanks in advance for any help.

Xposed MTC will not only dim using calculated times based on GPS position, but will also save and restore radio presets.
