Display Dual Zone

I was wondering if there is any possibility of having a dual zone functionality where the display would show (for example) GPS and music player or any other two apps (side by side, PIP, etc.)?

Figured out my screen dimming issue with the Klyde software on my Huifei - when I get a call, or open the Bluetooth app, it dims the screen to the lowest setting...

Other than that, I've had no issues.

Somewhere in this thread someone posted a link to downloading APKs from the app store, does someone have it handy? All I find using google is crappy sites.

Sygic in English

My unit came with Sygic but it is in Chinese. I can't figure out how to get it to English. Anyone have this issue or know how to get Sygic to English so I can use it?

Anyone?....no one had experiences with these?
[MTCB Android Head Units Q&A] Skitals:
That unit is completely unrelated to the units in this thread. Android 4.1 instead of 4.2. That said, despite the older android version it looks new to me. Software looks different that the AN-21 U units. Faster CPU and higher res than any of the other Android 4.1 units I've seen. Definitely a gamble unless you get more detailed specs, and are willing to be a guinea pig :)

Also keep in mind HuiFei/KGL now makes Volkswagen 8" units with a 1024x600 screen if you want a Android 4.2 unit that pertains to this thread. Here is an example with a 1024x600 upgrade option: http://www.aliexpress.com/item/2014...koda-VW-Golf-Passat-Polo-Seat/2023373550.html

Thank you SO SO SO much. While I can't follow everything, this gave me enough confidence to pop it open and remove the mic. I'd love to be confident enough to actually do what you did, but my knowledge of electrical engineering is just far too little to be able to do so.

I did find that the front of the unit, which appears to be most of the electronics for the android portion of it, comes off rather easily with 4 screws (on my device at least) Connected by 2 rather strong ribbon cables, and I was able to locate two mic wires run over the board and to a little circle marked Mic. For anyone afraid of messing it up...it's actually far simpler than I thought it would be. Look for the circle marked mic, desolder, connect an external to the rear mic out, and most of the background noise seems to go away. It's not perfect, but I believe that may be due to my use of an unshielded 3.5 extension and the placement above the steering wheel. When I have a few days off together I'll try to run a longer, better, shielded wire up and over to near the headrest.

One day I may try again with what you've said...and I shall look back to this thread for that.

Anyway to remove the preloaded audio player?

This is in relation to the ES9610AU 6.2" Capacitive 2Din Android4.2.2 Car unit.

I've loaded several apps (such as Rocket Player and Live365) that install and work to a degree but that apparently can't get access to the audio system. I just want a simple audio player that shows the filesystem on the SD card. I didn't see any way to remove or disable the inbuilt one. The other players show the SD filesystem but when I select a file to play they freeze up. The live365 streaming app loads stations up to 96% then freezes. There is never any sound.

Apologies if this has been answered before, but inn searching I didn't see anything specific on this.
[MTCB Android Head Units Q&A] typos1:
The best place to buy is Alibaba or Aliexpress, KGL, Klyde, Roadmaster and GS/HotAudio all have shops on those 2 sites, that way you can buy direct from the manufacturer and your ll know exaclty which type you are buying, you dont need to be "tech savy", a "developer" or anything, just use Google and a little common sense ! :)

I m unsure which version that is also, but I dont think it RoadMaster, it might be a new manufacturer. The launcher looks like a standard Android launcher, but I m afraid I disagree with you, skitals - I thats not a RoadMaster launcher, theirs is a complex, highly customised launcher that doesnt look anything like the one in that listing, you can see on the pdf.

There are also not "millions" of small factories making these units, there are the main 4: KGL/HuiFei, Klyde, RoadMaster, GS/Hot Audio, plus a "JY" unit mentioned once a few weeks ago in this thread and possibly a new one that Nice1 has bought, so thats 5, possibly 6, hardly millions ! :)

Also, have to disagree with you that "the only way to know what the unit youre buying is to wait til it comes : buy direct from the manufacturer on Alibaba/Aliexpress and you KNOW which version it is, or ask for a photo of the "about" screen showing the MCU version so you can identify it before you buy.
[MTCB Android Head Units Q&A] agentdr8:
It should default to English if you uninstall/reinstall (or maybe just clearing data). Try looking in the GPS card or the OEM app to see if they left you the Sygic.apk.

So for those testing out the experimental release of XposedMTC (1.2.8a), the dimming method now allows values as low as 1 (the default lowest value was 10). On at least 1 unit (from 1 user report), this results in a completely black screen, which was sort of my goal by overwriting their setBrightness method. Play with the dimming values to determine at which point your screen goes black, and then back up one or two on the slider. Of course, it's easier to do that when you can see what's on the screen, so maybe test this with wireless adb enabled so you can manually edit the preferences xml, or set the clock to 1-2 minutes before the non-dimming period so it switches itself back on.
[MTCB Android Head Units Q&A] Skitals:
It also assumes multiple manufacturers aren't just stealing the design and code. There are probably lots of clones running the same MCU version. It is after all pretty straight forward pcb design with all off the shelf components. The hardest part is writing the software for it all to work together. There are countless factories capable of manufacturing these.
[MTCB Android Head Units Q&A] typos1:
Well, yes, but then the unit wouldnt be "as described", I ve been dealing direct with the manufacturers, I find thats better than with the re-sellers.

My factory nav headunit has a function where if you hold a certain button the screen blacks out completely, could I suggest that you try and incorporate a similar function, maybe with a widget or something in the notification panel ?

Got my Kyde today, quite impressed so far, though the screen isnt quite as good as I hoped, the higher res would be better, when they finally get round to building it.

I ordered diversity/dual tuner DVB-T and they sent one with single tuner DVB-T, dont think they did it on purpose - I asked for that at the beginning of our "negotiations" and they probably forgot, still not happy with that, have to get them to send me the correct one. Theyre very willing to help, but theyre slow and not exactly the sharpest tools in the box.

Not much else to report so far, apart from the music player wont play my flac files, the KGLs advertise their player as playing them, double checked and cant see a mention of it on Klyde's listings, I assumed all the players were the same, might be an oversight on my part, or they may be different. I could use an app for music but I quite like the simplicity of the built in one, the right hand pane is too small though, so I ll root and change it for the modded one from the beginning of the thread, think its based on one from a HuiFei unit so maybe that will make it play flacs.

Nir,

Where did you connect the shielding of the conductor on the BT module? I'm seeing a GND connection on that board a few pins over from MIC+, but wasn't sure if you left it floating or connected it to the ground plane of the main PCB.

I have an issue with my KLG unit where the backlighting is on whenever the unit has power. When installed in the car the LEDs never go out.

I bench tested with only earth and the constant 12V connected and the LEDs came on permanently.

Upgraded from MCU 1.77 that came with the unit to 2.03. No change.

Any one else seen this?

I took my GS apart today and did some poking around. I found out that the BT module being used is a CSR BlueCore 6130. For the GS, it's mounted through-hole, and resembles the BT55. I found a datasheet if anyone's interested in learning more about the BT module.

what if you ground the dimmer wire? is it possibly an issue where the dimmer circuit is floating?

I know in my car tyhe dimmer circuit is flaky.. if I have my dash lights all the way up or all the way down the dimmer is either bright or dim, however when i have my dash lights in between the screen flickers bright and dim like crazy..

my KGL-7506 thriugh the LED's only stay on for about 30 seconds after power is disconnected from the accessory wire..

the screen blanks instantly.

[/COLOR]does anyone have a way to disable the "car-record" app on the KGL units(KGL-7506) from running at unit startup?

I have the front vew USB camera installed but I dont want the 'car DVR' function to operate at startup automatically.. but it does no matter what.

I tried loading startup manager but that 'car-record' app isnt in there to be disabled from startup.. im guessing there's an agent that just looks to see if the front view camera is plugged into USB and then starts up the Dash-cam recorder..

I find that dashcam recorder running when im trying to stream Music from a USB stick, bottle necks and my unit skips the playback.. yet if i manually stop the cam then it doesnt skip...

there are times i want the camera so I dont want to just unplug it from the back of the unit...

i'd like to just disable the app on startup and then start it when I want it.

[MTCB Android Head Units Q&A] agentdr8:
From what I can see in the MTCServer code, if the MTC Travel app is one of the last 30 running tasks, it sets the microntek.recstate pref to 1 at poweroff. At boot up, it checks this system preference, and if 1, launches the Travel app.

I could add a pref in XposedMTC to always write 0 the microntek.recstate pref when checkRecIsRun() is called.

Ok, my request might sound like a lot of work but I think it needs to be done before this thread gets much bigger.

Can we get a post showing each type of unit with its known 'good' and 'bad' areas? It would surely help new people much more than making them sift through over 400 pages of posts.

.....Also how should I go about requesting a section on the forums for Car audio? There seems to be quite a few out there now and I think it would help to find threads on each type if they have their own section.

....just my opinion, feel free to agree/disagree/ignore/help/other.
[MTCB Android Head Units Q&A] kwalsh24:
Agentdr8, I think I may have found a small glitch with the xposedmtc app & its auto dim feature, seems as tho after 12/1am the auto dimming fails to dim. Both lastnight and the night before I was out past 1am and the dimming feature didn't dim at all, the status bar said the correct update time and everything, but failed to dim, any other time frame before 12am midnight works fine?

I will check to verify I am running the latest version, believe I am.

Edit, only on 1.27, will upgrade to 1.28 and see if the issue is resolved.

Edit, car had been parked since 11pm, screen was dimmed at the time. Turned the car on at 3:45, screen still dimmed, updated all modules in xposed, relaunched xposedmtc, and it updated at 3:51am and the dimmer quit :(

[MTCB Android Head Units Q&A] bhitman:
xposedmtc (1.2.8): the same problem for me! After midnight the "dimmer" stays at 100%. When I dim the unit manually down, it jumps back to 100% after a short time.

Version 1.2.7 worked as well...
[MTCB Android Head Units Q&A] kwalsh24:
I think it might be a AM time issue, as it works perfectly fine in PM times. AM times don't seem to refresh the dimmer

Just to show, full brightness at 6:59am, meanwhile the app says the dimmer is to run ttill 7:27am

I ve got one of these:

http://www.amazon.co.uk/CSL-Receiver-Smartphones-Interface-Smartphone/dp/B00DZR3OKS

Was very cheap and very good, plus it has a removable antenna so a better one can be connected. It works fine on my Android tv box, it will work ok on the headunit too . . . . . until the car is moving, when the signal will come and go, even with 2 antennas connected - DVB-T isnt designed for mobile reception, the way round it is a diversity/dual tuner DVB-T receiver (ie TWO antenna sockets, NOT two antennas connected to one input). I ve not been able to find one for Android, so the best thing would be a diversity DVB-T box or card from one the manufacturer of your headunit.
[MTCB Android Head Units Q&A] cadillackid:
so im guessing it looks to see if a camera was ever plugged into the system and the app called once and then forever calls it on startup afterwords? or at lease until unplug the camera and restart the unit a few times?

the concept of a dashcam is great and the camera isnt bad.. but as I saw another mention the unit doesnt have the horsepower to play music, run GPS navigation and dashcam record at the same time.. I found that was totally my music crackle and pop issues.. when I press 'stop' on car record or have the camera unplugged my music plays perfect and GPS works perfect.

that would be great if you could put something in to kill that car-record app on startup.

im going to root and install xposedMTC as I love your features! what a great project!

for those in the USA I found a good cellular data solution that gives me 4G / LTE as well as allowing my airpin / airplay service to work.

I purchased a netGear Aircard 770S (AT&T unite) (not the pro).. it will power itself up into Wi-Fi mode when plugged into a USB port.

there are a couple options that i have tried so far which work to power it. you can remove the battery completely from the netgear device and as long as its the only thing plugged into the USB port on the KGL it will power itself only when your KGL is turned on.

you can power the netgear via a cigarette USB port in your car.

I have found that the AirPin app works very well for doing apple airplay, so if you have an iphone you can even mirror your screen. (havent tested with iOS 8 variants yet as ive kept my 5S on 7.1.2).. since it is WiFi to the netgear you just sync your phone to the netgear Wi-Fi network and then air[in is on the same LAN segment and works great..

you also gain the ability of having a Mobile Hotspot, unlike having the USB modem (many USB sticks are only EDGE (2G) in the USA).

just thought id share for anyone else looking for a relatively seamless car data solution.. (not having to power up a zillion things just to go drive).

GPS Test

Piece of junk.
[MTCB Android Head Units Q&A] Pavezer:
There has been a lot of discussion about the muffled and bass-heavy sound of radio and other sound sources sounding ok.

I was playing the radio yesteray and turned spotify on at the same time and they were playing on top on each other. And they sounded the same: muffled and bass heavy. I went to radio and turned it off and at the same time when the radio stopped, spotify output changed to sound clear and ok.

It's seems like in-device (radio) sound output has some written parameter that does some eq'ing or something else to sound output. Any idea what's going on and is there anything to do about it? Android sound output is obviously a different software module than in-device apps (?), but why on earth they are so different (soundwise)?
[MTCB Android Head Units Q&A] agentdr8:
The amplifier EQ is configured and applied to each audio output channel when its respective app launches. So the sound should be similar between Radio and MTC Music. But if you're using a different audio app with the sys output, then the EQ settings don't apply. It's possible the EQ settings are persistent until the source changes, so you might try launching MTC Music, exiting, and then try Spotify, etc.
[MTCB Android Head Units Q&A] Reptile-X:
A tip for those who need a app which auto start other apps after a reboot, I was looking for this but most autorun apps launch the selected apps but the app stayed open on top of homescreen.

After long search I found a app which launches a app with delay and then you can add another option to go back on homescreen with a delay. The app is called Autorun Autostart

For example: We have a app called Flitsmeister for the Netherlands to keep track on speedcams, while you get closer to a speedcam or a mobile speed control this app will warn you with a toast and sound. With Autorun Autostart, after a reboot I set it to launch Flitsmeister at 50 seconds and 55 seconds to go back on homescreen. This works great, this way I don’t have to think about launching the app every time I step in to car.
[MTCB Android Head Units Q&A] typos1:
The units are very very similar, far too similar for different threads - they are all Rockchip tablets mounted in a double DIN chassis, controlled by an MCU, the MCU software code for all units is incredibly similar. It would be silly to start an entirely new thread because one version has very slightly different MCU code, a different amp IC and a different radio IC (still from the same manufacturer just a different model).

It is large, but its not confusing . . . . if you have the time to read it or youve been following it for a long time.

What would help is if the info pages and wiki were updated - a lot of things have been discovered since it was last updated. A more comprehensive guide explaining each unit's positives and negatives would reduce confusion for newbies.

Having said that, there are still a lot of posts from people asking questions that they could quite easily find out themselves (thats not aimed at you two) if they read the first page or did a thread search, the most common being "what unit is this . . ." - all the info for identifying units is on the first page, a lot of people are lazy and want "spoon feeding" as some XDA mods call it.

I m not so sure now - the chip in the Klydes looks the same as the one in the KGLs.

I tried grounding the line marked Ill ( illumination ) which didn't help. When grounded no change, when connected to +12V there is a slight dimming of the screen, no change in the LEDs.

Mine is a MK4 Golf. No can bus.

Do you see "shutting down" when you drop the ACC input, i.e. turn off/remove key, or does the unit just poweroff instantly.

The car <-> HU power harness on mine originally had the constant 12v and ACC swapped. It meant the unit turned off instantly and LEDs went out when the car was turned off but it would not maintain radio tuning info.

[MTCB Android Head Units Q&A] kwalsh24:
No problem, we all are the testers so we may as well give feedback when possible, love the app tho, does a clean crisp job of dimming! Like how it remains dimmed even after a shut down & restart
[MTCB Android Head Units Q&A] cadillackid:
mine actually says "shutting down" when I remove the ACC power. it appears to go into some type of suspend for about 30 seconds.. as the "shutting down will apear" and then the screen blanks.. the LED's on the hard-buttons stay lit for about 30 seconds or so.. if I return power to the ACC I get an almost instant power-on and return to the last app I had running..

though it does appear to go through the startup, as it will re-start the car-record even if I had stopped it before...

im working on a circuit controller to start my unit up from when the car door is opened.. since my car all the sounds go through an Amp, I found that I wont get any sound until I would actually turn the key so my unit could easily be almost started up by the time I start my car to go... without the 35 second boot time.. (well the boot time is there but im busy getting in my car and getting settled in..
