Someone removed that button out of SystemUI and posted it last week. I installed it in my Malaysk rom ok. If I tried to use the software off it would reset/reboot my hu. Long press would bring up a menu to reboot.

Look at #14191 for the file.
[MTCB Android Head Units Q&A] comptechltd:
I looked and looked but couldn't come up with anything. It has something to do with the bluetooth stack which each manufacturer does differently....or so I read. My solution was to get a Samsung S5. I didn't try a FDR on my phone....some say that may help. (My contract was up anyway.....lol)........Sorry I couldn't be more help.

I am on the Malaysk June rom for 3188 1024 x 600 installed on Joying HU mcu 2.59 (loud). After updating I've noticed that my SWC buttons work sporadically. Even more weirdly, when they work the volume knob on HU does not. Anybody ran into this problem?? Thanks.

I just want to make sure I have this correct and nothing has changed. I am using [MENTION=3590033]Malaysk[/MENTION]'s latest ROM. I believe he has PowerAmp set to autostart. I don't want it that way so if I understand correctly I can delete his /etc/install-recovery-2.sh and using [MENTION=3744488]devilsoft[/MENTION]'s program create a new /etc/install-recovery.sh with what I want to autostart?? Any special way to delete the /etc/install-recovery-2?? Just wanting to make sure I don't hose my installation.

Thanks,

I am glad to read that !!
[MTCB Android Head Units Q&A] DJCannonball:
I installed my 2 amps, my sub, my crossovers, new speakers in the dash, new speakers in the doors extra tweeters on top of the dash and i used sound deadening material in all the doors.

now with this much difference in clearity and denfinition, you can hear every tiny crackle and scrisp in the audio. due to that, a new problem pops up:

the quality of A2DP stereo streaming via bluetooth of my KLD unit isn't any good.

The soundquality is not horrible, but the very top-end (hihats/ride/ and triangle-like) sounds not right, like badly compressed sound.

I have a Sony Xperia Z2 phone, which streamed A2DP perfectly clear with my old headunit on my previous car (which also had extra tweeters on top of the dash).

When i transfer the same MP3-file (320kb bitrate) from my phone to the sd-card of my HU, it sounds way more clearer, a big difference.

I know how good A2DP can sound, but it doesn't sound right on my KLD HU.

i recently flashed MCU 2.55- music, so first i thought the MCU-music isn't right.

Therefore i changed it to MCU 2.55 without the music enhancement, it didn't make any difference in A2DP.

i changed to an old MCU 2.40 that also doesn't make any diffference in A2DP.

i was on a firmware from 10-6-2015. i flashed an older firmware from 2014. that also didn't make any difference.

about 4 years ago i had a similar issue with an LG optimus phone. when i changed to a customfirmware on that phone, the A2DP quality was verymuch improved. the writer of that firmware tackled the issue: it was a bluetooh protocol negotiation issue between certain types bluetooth radios.

I know my phone's A2DP works perfectly with other high-end systems, but not on my HU.

Yet i have to test some other bluetooth sources on my HU to see (hear) if they sound right.

Anyone else had this problem?

Ya, I was going to get that one since it was Prime too but I wanted a bigger screen so I rolled the dice and went with a model with a longer delivery date hoping it'll really get here in 7 days (other items I got from Amazon with month long delivery dates actually got delivered in a week).
[MTCB Android Head Units Q&A] obioan:

[MTCB Android Head Units Q&A] kaween:
Yup. BT streaming on my JY sounds like its 32kbit -in other words, sounds like cr*p-. Hence I never use it.
[MTCB Android Head Units Q&A] obioan:
Can I set the unit to boot regardless if I turn the key in contact or not?

Can the unit be set not to shut down when the engine stops?
[MTCB Android Head Units Q&A] OneCheekyDevil:
The unit can be wired to have constant power (IE - bypass the ignition key). I would advise in having a manual power switch wired between the unit and the battery.

By leaving the unit constantly powered, it will drain the battery, and depending on the health of the car's battery, you could find it completely empty within a week.
[MTCB Android Head Units Q&A] DJCannonball:
i get it, if it sounds like crap, you don't use it. but it can sound great (if the bluetooth-connection negotiation between your phone and HU is correct)

i also took notice that modern bluetooth devices support ATPX (like my Sony Xperia Z2) which has a higher bitrate for streaming audio.

i hope in the near future our HUs will get it too from 5.0.1 Lolipop

Hi,

i just purchased this Head Unit from pumpkin on ebay, its the version from Klyde. Just unpacked it an have it on my workbench.

At first i ordered the Car-FM Amplifier mentioned earlier in this Thread and a new micro SD-Card with SD Adapter. With this Adapter i wanted to see what is on the Micro-SD Card that came with the Unit an where the Navigation Software is stored - surprisingly my BitDedfender Antivirus says that on the iGo.apk is a "Android.Trojan.Agent.gLXN" hidden. I uploaded the File to Virustotal.com and 13 Scanners, including all big Scanners show a positive Trojan on this apk. Aehhem...i am aware, that some Files can give you false positives, but i am alerted. It is a brandnew unit. Is the iGo.apk known to give false Trojan positives? It said that res/layout/mapp_browser.xml or imapp_browser.xml would be affected.

Anyone else got trouble with the Navigationsoftware that came with the unit?

Where can i get a clean version of the apk?

Another thing is, that i would want to use this Headunit as a recorder for a dashcam. Which App would you recommend? And what kind of small camera, any advices?

I have got an HSUPA USB Stick Model: MF190 from ZTE Corporation. Will it work with the afore mentioned Headunit or will only work special 3G Sticks?

Hi guys. I'm attempting to upgrade my rom and I want to be sure I'm doing it right. I've got MCU version MTCB-KLD-V2.40 the build is rk30sdk-eng4.2.2 28012015.11:29:55 and the android is 4.2.2_28012015 I was going to go to coudu's latest 4.4 image for kld at 800x480. Reading the first page it looks like I just need to DL his rom and drop it on the GPS card. Is that correct? I don't want to mess with the MCU at this time.
[MTCB Android Head Units Q&A] typos1:
As the first page says, the MCU and Android are separate and firmware versions are interchangeable (as long as you pick the right processor type and screen res for your unit), so your unit type is irrelevant if you are just upgrading Android.

Latest features like shut down timer wont work if you keep you old MCU. Its best policy to update teh MCU tot eh latest version and only downgrade if you have problems with it.

Yes, as the first page says, stick it on the GPS card, or you can use the SD slot or usb and do it from recovery.

[MTCB Android Head Units Q&A] 1-2-Hak:
Was looking at power when I am in recovery. If you turn off the acc in recovery the unit stays on. This is suggesting that the mcu is controlling the power off.

Can someone who has canbus without an acc circuit to the radio let me know if the unit comes on like a quick resume when it gets a canbus signal. My guess is that in the canbus scenario the unit goes into standby and resumes quickly.

Anyway the bottom line is the mcu should be able to change to increase/or stop the shutdown after acc is turned off and go into suspend mode instead.

Just installed Sygic. If I set the radio to a comfortable volume I can very faintly hear Sygic voice.Is there any way to increase the Sygic voice volume ?

[MTCB Android Head Units Q&A] kwalsh24:
It does, I have a video posted on YouTube that snows the issue that my canbus has, the radio goes into a standby mode after a minute or two with the key in the ignition, once the canbus decoder detects any sort of signal in the system it turns the radio back on which is relatively instant

[MTCB Android Head Units Q&A] agentdr8:
I think you also have to select Sygic as the GPS app in that screen. Something tells me they use the app selected to know which package to watch for in the AudioManager, in order to lower the volume during nav output.

Also, to get the TTS voices I just downloaded them from the Sygic store built into the app. Worked fine for maps too.

This may not be possible if the kernel wasn't compiled with loadable module support. I haven't checked that though.

Would be nice if we could also select w

which music app to monitor / watch like the gps app.

Do you know if they plan to release RK3188 SOM with 2gb of ram and 16gb of storage?

Thank you !
[MTCB Android Head Units Q&A] typos1:
Its up to you really, you gotta ask yourself if you think its worth upgrading or not and I d wait until we have a fix for the 1024x600/RK3188 screen problem anyhow.

Someone posted pics of the RK3288 SoM for the Firefly dev board a few weeks back and someone else rightly pointed out that it would not fit in these units, but thats hardly surprising as it was designed for the Firefly dev board. RK3288 SoMs for these units will obviously be compatible.
[MTCB Android Head Units Q&A] doctorman:
our Dear ROM developers mainly [MENTION=3590033]Malaysk[/MENTION]:

can you please use something like AROMA installer so we can chose which launcher , Radio, Music etc app will be installed with the ROM?

this way we can chose Next launcher, or original KLD or JY all in one ROM.

this should cut back on the requests for different ROMs and make easier to update the ROM.

I am not sure if the screen Res can also be combined into 1 ROM so it can we can reduce the number of ROM options down to quad core or dual core.

I have 1024x600 resolution using Malaysk rom for correct cpu and resolution (NEW from June 10, 2015 for 1024X600 downloaded from his signature).

I didn't do factory reset after ROM update, maybe this is the reason?

BTW, everything else works, that's the reason why I didn't do a factory reset.
[MTCB Android Head Units Q&A] markcm:
What "screen problem" are you referring to?

I have a fairly new KGL that has 3188 and 1024x600, I have upgraded to the v2.55 with Musik MCU and running the latest Malaysk ROM, I'm not aware of any issues on my device.

I'm a bit shocked to see these 3188 SOM's selling for $120 or whatever it is, the upgrade cost for quadcore 3188 and 16GB when I bought my KGL last month was only $20 from my seller. I suppose that is the "aftermarket" for you.

I'm trying to understand the Memory in these as well. When I bought mine recently the original MCU/ROM were configured such that the 16GB memory was partitioned into about 1GB for the Internal storage and 14GB or so for "data". Now that I have updated the MCU and ROM, the 16GB memory is divided into:

1.97GB "Internal Storage"

11.53GB "NAND Flash"

I'm having a bit of a hard time understanding these partitions, I'm assuming there may be another 2GB that the system doesn't report which is for the OS. All of my apps want to install to the 2GB "Internal storage" although from settings/Apps I can move some of them to "SD" which is the "NAND Flash" partition. For example, I can get Slacker Radio to install to the "Nand Flash" which in the system denoted as "Move to SD" but all the cached music stays on the 2GB "Internal Storage" partition which fills up quickly.

Can you get into recovery by using the reset button? As it was mentioned here, the reset button is directly connected to PCB and should always work, regardless of the MCU type you flashed. If you can get into recovery that way, you can select options using an USB keyboard and flash a right MCU.

A new SOM won't change your flashed MCU!

I think the chances are close to zero. Rokchip (the maker of the chipset inside our units) would have to release new drivers. And they probably never will for RK3066, there are some tests for RK3188. You can install Lollipop on any device as long as you have working drivers for all the HW (chipset, WiFi, BT, GPS, Audio, Screen etc.)

Lollipop only needs 512MB RAM. But you couldn't do any multitasking with it.
