Hey nroeber78,

I'm having the same issue with wifi. Can you keep me updated on your wifi progress? I'll be sure to do the same.

Thanks.

---------- Post added at 02:02 AM ---------- Previous post was at 01:44 AM ----------

The radio issue could just be a setting within the Factory Settings section. Go to Settings > Factory Settings > password is 126 > Application > Radio setting. I have a Klyde S07 as well and my Radio is set to TDA7786.

Good luck.

Wifi Dropping Issue

Hello,

It seems that i am having a wifi issue with my unit, I tried both 1.86 and 1.77 the same issue is appearing, Randomly the wifi signal gets lost and I have to turn of the wifi and turn it back on to make it work again.

the issue happens more often when i download files or install applications from google play.

is this a hardware issue where the wifi module is heating up? can there be a fix for it? I tried to search and found this fix below, do you think it will help?

http://www.freaktab.com/showthread.php?1997-Potential-WiFi-speed-signal-fix!!!-(Thread-Closed)&

the above fix is for the same chipset RK3066 but it is intended for tv dongles and i am not sure if our headunit comes with a broadcom chipset wifi or not.

HuiFei - 2 DIN Pure Android 4.2.2 A9 Dual Core Car Stereo Radio Head Unit

I bought an OBD2 device from the seller with my unit, it came with Torque, but it looks like it's pirated, can't install the plugins I had previously.

Do the developers of software such as this, and iGo just not care, or is it to much of a headache to try and stop?

[MTCB Android Head Units Q&A] kwalsh24:
Yeah, if that launcher were to work, it be nice to have all the apps from it to, to see if we can make a hybrid version. 4.2.2 os with the launcher and apps, likely have issues with the apps running 4.2.2 vs their 4.1.1 os. Then again maybe not
[MTCB Android Head Units Q&A] agentdr8:
Negative. I spent hours trying to get iGo TTS to work, both on the supplied version and the latest. For some reason, it would just crash any time I copied the TTS voices to the sdcard. I finally gave up and installed Sygic, which works great and the TTS is functional.
[MTCB Android Head Units Q&A] kwalsh24:
Hmm, may have to go that route then, I coukd get the Tts voices go show, just no sound would play. Now I can't even get that to happen

What version of sygic are you using? Totally new to me would have to track it down along with the maps

[MTCB Android Head Units Q&A] J0sh_FG:
WOW could u extract all the apps from that launcher too? It will be awesome. I've been keeping an eye on these Avin Avant 2 units since 4-5 months ago when they were released.

Btw, the hardware on CA-FI and Avin Avant 2 units seems to be the same too. They use a Dual Core 1.0 Ghz CPU with 1GB RAM. Their screens have a capacitive display too but.. with 1024x600 resolution. Not sure if the menus and the homescreen will look exactly the same in the 800x480 HuiFei's sceen.

I loved Avin Avant 2 units from the beginning for its UI and its screen but HuiFei radio has better performance for half the price if you are buying e46 version from an European country .

Keep us updated please :good:

[MTCB Android Head Units Q&A] parazit26:
Yes sure. I have sent a message to [MENTION=4036493]kwalsh24[/MENTION] with the launcher apk. Waiting for his answer. If the launcher will work, we can continue with the other apps.

[MTCB Android Head Units Q&A] gazdaaa:
But all other roms (i believe) have this by default, why [MENTION=3590033]Malaysk[/MENTION] roms doesn't have this?

Another question:

How can I make the radio app to stop playing and switch audio focus to PowerAmp, when I run the PowerAmp?

Possible solution:

Can you [MENTION=434511]agentdr8[/MENTION] (because you are working on mode switching, and I see that using current mode switch things work as they should) make an app shortcut that will first broadcast the same intent as the music app (to switch mcu music source to android) and then launch poweramp?

(the antenna is in the middle under the front window)

- My OBD2 Bluetooth Module is connectet, but when i open torque it says "blueooth not enabled"

Software is "KGL_KK444_800x480_150521_root_mod_boo_201506-10"

Can you help me with my faults? Is there an other compatible, better, gps antenna?

"Unfortunately, Settings has stopped" - what causes this error?

I get this message every time in settings, when trying to access "System" or "Extra Settings". All other settings seem to work. I am not sure what I did to cause it. I was testing diffrenet MCUs and also installed diffrent things and did not immediately notice it. I have since reverted to last stable MCU i think worked and even did a factory reset. Did not help. I am on the latest Malaysk ROM and MCU 2.47 KGL4. Any suggestions?

UPDATE: It is caused by the 240 DPI setting as explained by Malaysk. I forgot all about it...

[MTCB Android Head Units Q&A] kxdelta:
I ended up doing some work on this today. I bought a Mono Jack Extension cable on Ebay and cut it up to get the socket half. Then I soldered it to the marked pins MIC- and MIC+ on the back of the bluetooth card directly (I bent it forward slightly too). I also removed the coupling capacitor C102.

Then I plugged in an official parrot microphone.

It's definitely an improvement and the levels are better but I wouldn't say the quality is fantastic. Doesn't seem to be any kind of noise cancellation. It's probably actually better quality to just use the phone itself on speakerphone than to use this but that defeats the auto muting music etc. It will do for me, I don't make phone calls that often. Android microphone also continues to work fine.

I put the cable out through the unused DTV opening on the back of the unit and taped it to the GPS antenna next to it to provide some strain relief (don't want the outside cable to pull directly on the BT card)

I understood you were trying to recover an apk from an image file. Anyway, you can extract the apk with this tool and then copy it back to your HU.

Mic amplifier on KYD

I receive this part from Ebay :"http://www.ebay.fr/itm/281488056291?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT"

Before I maid the modification on my HU for separate the Internal mic ( android ) and the external mic then less noise but the level on the external mic with the bluetooth card was too low....

With the card that I receive, I remove the micro and use only the amplifier part. I connect the external mic at the place of the mic and I connect the card directly on the input-mic of the HU ( power supply is directly from a usb power ( with 2 diodes for down the power supply under 5v, before I have 5,3v and the sound was at the good level but not good to heard ).

Now all is ok, no noise with the bluetooth and the level is ok

Can't somenone make a software from which we can manually change this settings? :D
[MTCB Android Head Units Q&A] markcm:
I have two dealy features I am using, one is hardware (

ELK-960 delay

) and the other is Malaysk software (ROM)

The ELK-960 delay timer is a small circuit board with a relay and a delay timer. I cut the ACC wire between my car and my Head unit and installed this timer between. The 960 is very configurable, I set it up to start timing when the ACC wire goes to low signal. What this does it keep the signal to the HU high after the key is turned off for a period of time which I set on the 960. This tricks the HU into thinking the car's key is still on during this delay period; there is no change, the unit stays on and playing music or whatever you were previously doing until the time period expires; if you put the key back to ON position the timer will cancel and this cycle can start over. If you do not put the key back in and the timer expires, the HU will then get a low signal on the ACC line and boot down. This is great for making quick stops like the gas station, I set mine to about 20 minutes. You do have to pause your music with this method.

The "SLEEP" function in the new ROM I installed from Malaysk senses when the ACC line goes low and causes the unit to stop all activity, the screen goes dark and the unit goes in to standby mode for a period of time which you can select in the settings. Once the time period expires, the unit boots down completely. If you turn you key on before the timer expires, the unit comes back almost instantly to where you left off.

Now that I have upgraded my ROM with Malaysk's version, I have set my ELK-960 delay timer to 10 seconds and I set the Sleep mode timer to 30 minutes. When I turn my key off, the head unit stays fully active for 10 seconds and then everything pauses and the HU goes to sleep for 30 minutes and then boots down, unless I put key back to ON before 30 minute time period expires.

Some time i can not acces gps card only if i make restart or wait sore time. It from card or this new mcu ?
[MTCB Android Head Units Q&A] agentdr8:
Maybe it has to do with the default DPI being higher.

I already made this; it's the MyMusic and MyRadio launchers that are part of XposedMTC. Once you set your preferred music player (Poweramp), you use those shortcuts to switch between them it'll switch audio sources so you don't get overlapping sounds.

You'd probably have to inquire as to how darkleo is making the changes. I'm guessing hex editing, unless he's got a way to disassemble/reassemble. Highly doubt a way could be made to configure these settings from within Android though.
[MTCB Android Head Units Q&A] markcm:
I have updated my KGL1 with this latest MCU 2.55 with musik update. Everything still seems to work including sleep timer. I did not need to make any changes, radio works too.

Audio quality does sound more full although now I hear slight hiss at all times when volume off and even when mute applied. It is very slight and the improvement is worth keeping.

I still struggle with over compressed treble when streaming Bluetooth audio and hope to find advice how to resolve this. .

I have a question about native EQ when using Poweramp.

It seems the factory EQ is still active when using Poweramp. How do other users manage the factory EQ and the Poweramp EQ?

I do not want to make factory EQ flat because I use other music apps such as Slacker radio and Amazon prime music.

I do not have a problem but it seems weird to have 2 EQ active at the same time.

Someone had reported battery draw in sleep mode to be 600mA, this should not be a problem if the car battery has reasonably good health.

---------- Post added at 08:40 PM ---------- Previous post was at 08:29 PM ----------

Are you making reference to "Factory Settings"? In the main top settings directory?

If you enter 126 to view Factory Setting you will view addition settings specific to you head unit, just viewing will not reset.

Maybe I am not looking at the same area as you. If you are looking at "Backup & Reset" and then " factory data reset" I don't know if you need the password 126 in this area but yes it should delete everything.
[MTCB Android Head Units Q&A] agentdr8:
No. Factory Settings is just another settings window, but for MCU options. It's not a factory reset.

You need a recent 4.4.4 rom to utilize sleep, in addition to the MCUs that have the timer built in.

[MTCB Android Head Units Q&A] Reptile-X:
I quote you guys/gals since we talk about this, and trying to keep you guys updated with the amplifier IC issue.

The unit is working now with an external amplifier, like I said before I don’t have front cinch connections on my unit, so I had to use high inputs (speaker wires) from the head unit, I got myself a dirt cheap Caliber AC 450 at whooping 59 Euros, it was on discount and I was in need in a high input amplifier so it was all good.

About my unit not having front cinch channels, I look back in to the pictures from the seller and it has a wire loom with 11 connections and I have only 8 connections and that explains why I am missing the front cinch channels, so I contacted the seller and the guy is asking 50 euros for a lousy wire loom. I replied back to him, since it was wrong cable loom from the start, he says it is my fault I should see that a year ago…

Anyways it took me 2 days work to install the amplifier because of the rain, had to remove all seats (front and back) to get the wires to the amplifier in the trunk, signal wires are gone through left side of the car and the +12V went from the left side directly from the battery (20mm2). Soldered all wires and connected to the head unit and it works perfectly now, I have even much better sound quality. Tested for an hour and everything is fine.

So my conclusion is: This head unit can’t handle the Pioneer speakers I installed.

Kaween, I didn’t have issue with the amp control wire, the head unit is shutting down the external amplifier, and I was already preparing a relay to fix the problem if it was like your head unit, but luckily that was not the case. :)

Here some pictures of my 2 days struggling…

Pulled a cinch cable from the rear channels, in case when the IC goes busted again, so it is sitting there and being pretty, didn’t have to use it:

After install finished:

It is nicely hidden under the second compartment of my trunk:

Some update about the Wi-Fi antenna I used, it is working partially, before I couldn’t get even 1MB/s now I see speeds up to 8MB/s but the Wi-Fi goes still off after a while, and to be exact after downloading around 840MB it stops working till I disable and re-enable the Wi-Fi, before the antenna update I couldn’t even download 200MB so it is still better than before and I see much better download speeds, unfortunately I can’t download the 6GB TomTom Europe map from official TomTom.
