I wanted put it out there I have found an eBay seller who appears to be willing to sell SOM cards. I reached out just to see and got the typical no, only compatible from the factory B.S., so I called him on it, politely, and told him exactly how it is done. He came back with a totally different tune and said send pics of my unit and maybe they would be able to sell me a RK3188 with 16GB ram. I'll let you know how it turns out.

I've tried but it won't launch (it doesn't launch xmtc, just does nothing), do you have another idea how to accomplish that, maybe some new apk that's shortcut to mymusic and myradio, but is separate package?

I've setup gps mixing for iGO, when using it with radio or music it works as configured, but with poweramp it first lowers (when the voice of navigation starts) the audio from poweramp, and in the middle of the navigation voice duration rises back, then when the navigation voice is over, it lowers down again for the rest of the duration thst it wasn't risen down.

Has any one experienced this, or maybe fixed it?

Hey guys,

Is anyone having any issues with their GPS slot? Mine seems to have stopped working. Anyone have any idea's what might be causing the issue?

I've tried the card in another slot and it works, I've also tried a different card in the GPS slot and that one doesn't work either.

Not sure if this is relevant or not, but I'm using Malaysk KLD 800x480 from June 7th and the Darkleo modified MCU version 2.55.

RDS auto frequency change

Hi,

Does anyone system change frequency automatically when driving to another frequency area of the station being listened? Mine does not change the frequency and I need to search the new station frequency manually... AF option is selected and I have RDS showing station name.

I have KLD with MCU 2.55 with malayks os.
[MTCB Android Head Units Q&A] mike.s:
Are you sure the station is sending AF information? Just because it's sending PS (program service - station name) info doesn't mean it's sending AF info. Does AF switching from that station to another work with other radios?

[MTCB Android Head Units Q&A] DJCannonball:

No I don't have an updated BusyBox. I can update it but why?
[MTCB Android Head Units Q&A] agentdr8:
I guess it depends on how the PIA app works, but most of them are just a frontend for the openvpn binary, which then uses busybox for things like adding routes. You could always run the openvpn binary from shell and see if it throws any errors to console or logcat.
[MTCB Android Head Units Q&A] 1-2-Hak:
Thanks guys for the feedback. It confirms my theory that the mcu is actually controlling the power off.

It looks like the unit listens for events such acc signal to make the unit initally power on. Once the unit is on it listens for another signal to turn it off. At this stage it sends a broadcast to Android to do a 'suspend' and shows the power off dialog. After a period of time ' I believe coded in the MCU it cuts the power to the android part of the unit (I assume to save battery) and the process starts again. The signal from the canbus is more like the power button on the unit. It tells the unit to suspend but doesnt even do the power off.

When I boot into recovery I assume the MCU doesnt load so the power just stays on.

So anyone know how to decompile the MCU?

I've managed to get the latest igo to work with tts on my phone, its a Aussie female voice using a svox engine. Its okay, haven't fully tested it but its work. Now to see if I can copy it over to the radio and maintain the tts
[MTCB Android Head Units Q&A] xrapidx:
Interesting one for me this morning, device didn't turn on automatically, I noticed after about 20seconds, pushed to power button, and the Android logo was displayed for about 5 seconds, then the default screen.
[MTCB Android Head Units Q&A] agentdr8:
I just upgraded to 1.86 and I too am seeing the poor wifi issue now. How are you extracting the kernel from the 1.77 update.img? I'm guessing we can just dd an old kernel over the correct partition?
[MTCB Android Head Units Q&A] 1-2-Hak:
I just updated the mcu.img from the sd card and then just flashed the system.img through the bootloader. Then it doesnt wipe your device and keeps your same setup.
[MTCB Android Head Units Q&A] saifbarry:
Yeah I've seen that happen when I power off the unit using the power off button before shutting off the car. Next time I start the car, the unit won't power up until I press the power button. Then I get the android logo for a few seconds and then launcher. But I've had it do the same to me once or twice when I could've sworn that I didn't manually power off the unit before hand. My memory isn't the greatest in the world so I didn't think too much of it.
[MTCB Android Head Units Q&A] xrapidx:
Hopefully its nothing - I've never done the manual power off.

Relating to that, is there away to force the system to do a full restart? I've had occasions where something stops working, e.g. the volume knob - and don't really want to stop the car to reset.
[MTCB Android Head Units Q&A] agentdr8:
Either get a restart widget like Quick Restart or jab the reset button.
[MTCB Android Head Units Q&A] xrapidx:
As simple as that? Didn't want to try the reset button, I was scared it reset to factory.
[MTCB Android Head Units Q&A] saifbarry:
Confirmed, both method work. I personally use Wigetsoid for the restart widget and some other quick controls like WiFi tethering, media scanner and brightness control. But neither is a graceful restart.
[MTCB Android Head Units Q&A] optx:
Where to get the system.img, is this the rooted system.img you posted some time ago ?

Blankers, could you please tell me what you did? I do not understand what agentdr8 said. I already set GPS button on the unit. but voice is low.
[MTCB Android Head Units Q&A] alsolh:
I extracted kernel.IMG from update.IMG and flashed using flash_kernel to kernel partition over WiFi ADB

Before doing that please backup your system using TWRP recovery just in case

Please note that still I am facing the WiFi signal dissappearance issue but much less frequent with the 1.77 kernel
[MTCB Android Head Units Q&A] 1-2-Hak:
I have put one together but havent tested it yet. Its pre-rooted so doesnt need the root exploit. Has supersu.apk but will need it updated once you run it.

It's only the pty translations that has been modified in the above mentioned APK.

I will post a short guide on how to install the radio APK later...
[MTCB Android Head Units Q&A] DJCannonball:
You need a rooted headunit. And a root Explorer. Radio app must not be running.

Delete. Mtcradio in system\apps. And reboot. Then install updated mtcradio5.

But never mind, I tested it. Still doesn't AF ever[emoji20]

[MTCB Android Head Units Q&A] maverick_37:
Hi Reptile,

At the moment not enough time to read everything in the forum.

I was thinking that maybe a better option is to use a NTC resistor, so that when the temperature goes up the fan automaticly speeds up due to the fact that the value of the resitor changes with the temperature.

Don't know how to do this yet but don't have received all the components at the moment, so still time to find out.
[MTCB Android Head Units Q&A] kruuth:
I noticed that my unit does not have a cooling fan in the back like some do. Should I put in a cooling fan or something? It looks like it has a knockout for it or it's cast for it or something but the back is sealed up pretty tight.
[MTCB Android Head Units Q&A] MayfairDROID:
Older KLD units had fans, but not many. Some have put fans in, but most have not.
[MTCB Android Head Units Q&A] kruuth:
Is it worth putting a fan on it? I'm not even sure if I could on mine.
[MTCB Android Head Units Q&A] Reptile-X:
Hi Maverick,

To be honest I am using the fan as it is now for couple days and I can’t hear it when the radio is on, even if the radio is off I can barely hear the fan.

I didn’t even use a silent fan, so maybe you could get one of those and don’t need to slow down.

Better solution would be this here:

http://www.ebay.com/itm/160494489350

But like I said maybe that’s now even needed with a low noise fan.

[MTCB Android Head Units Q&A] ErAzOr2k:
anyone?
[MTCB Android Head Units Q&A] kaween:
Which is why I chose not to connect it to the ACC but to a control line (Amp Control, Antenna control would work too) instead : that way, the fan only runs when the unit is running.

Radio off ? No fan. No noise.

I used an extremely silent PC-fan which you can hardly hear at full speed and with radio on, yet volume muted. You can only hear it running when you shut of all other stuff in the car (engine obviously, but also the car's A/C must be shut down completly in order to hear the radio-fan).

This ellimanted the need for any type of speed control due to noise reasons. If you're looking for dead-silent fans, Scythe makes some mean virutally noise-free fans of very high quality - I really like using them-.

Hmm : shot in the dark : did you do the "reset everything" routine after installing Malaysk's rom ? There's a reason why he writes it's mandatory to do so after installing his rom.

If that doesn't do the trick, did the problem occur directly after installing his rom, or did it happen well after doing so ? Does using an older version, or a DSA version make any difference ?

In all honestly, I've gone back to DSA's rom because Malaysk's (excellent) rom did not permit me to install and use the USB-based TV tuner software which I use -on Malaysk's rom, I got a "device not compatible" error when launching the tuner software, although it did install correctly and without error, where DSA's has no issues with that.
[MTCB Android Head Units Q&A] Reptile-X:

I was doing the wifi mod to improve the signal and I think I have damaged the LCD screen when I was putting everything together.

When I turn on the car the screen displays white. Everything else works including the touchscreen and audio.

When I opened the unit back up I noticed this part was broken. Could this be the cause of my screen not working? Is it hard to replace and solder a new component on? What is this component? A small inductor?

The grey piece in the middle. I tried to reposition it to see if it would fix it. It has the 220 written on top of it

[MTCB Android Head Units Q&A] clearchris:
If you feel confident with an iron, I dont imagine that is a hard repair. Some quikchip might come in handy, as the copper may wick the heat away. If you do use chipquik make sure to remove all of it before replacing the inductor.

Hi,

I ordered the amplifier, and just have a quick question about how to connect it:

The connectors on the amplifier are: VCC, GND, OUT.

VCC and GND are for the power, and OUT is the actual sound, right?

But a microphone input have both "+" and "-" so how can I connect the OUT to the microphone input?

Maybe connect the OUT and GND to the "+" and "-" of the microphone input, and the VCC to the power?

That makes sense, but then I have only "+" for the power step down, without "-"

What am I missing?
