Wi Fi seems Better

OK I am running the KGL unit and the Wi Fi seems quite good now, which may be because I have changed the Wi Fi security to none , with phone set to only allow known devices. I have also switched the optimisation off.

Spotify seems to work very nicely now. .Poweramp is fantastic , but was always good. I also use face book messenger for conversations with my daughter who is OS and it's pretty good taking while I drive.

The biggest downside of the unit now is the Phone app, store surnames first with no option to change. Joins the names together as well. Voice quality is very poor I am told so I'll try another Mic and see if that improves things. Thanks for all the assistance, starting to get to understand things a little better. The ideal phone app would be one that links to contacts, which the GPS could also use. Any suggestions would be greatly appreciated.

KGL unit with 2.09 install now. As per my last post I think I have cured the slow wi fi, by removing the security encryption. Every thing seems quite good, just need to clean up my install and try and get the phone working better with a better Phone app. I am after ideas for a good phone app.

Do you have 2 way CAN Bus working ?
[MTCB Android Head Units Q&A] agentdr8:
The default behavior of the stock MTCManager is to store the foreground app as the "last" app during shutdown, which it then restores when you power the unit back on. There are no settings to change/alter/disable this behavior. I could probably add it to XposedMTC if you truly do not want anything to be restored on boot-up.

Unfortunately these headunits don't utilize a normal RIL for phone communications, so none of the 3rd-party dialers will work. The Phone/BT apps were designed specifically to work with the MCU to provide handsfree calling and Android BT support (for OBD, and very little else). The only decent solution that I've found is to run a phone-to-tablet type app that communicates over Wifi to send dialing requests to the phone from the headunit. I use Tablet Talk and it works well enough for my usage. A bonus is that I can text from my headunit while driving, which is neither safe nor illegal here! :D

Hi guys

Real problem.. New in Android

I bought a new android screen for my honda civic car with dashboard around it .. And i have ig and my country maps on the SD .. I didn't know how to install it .. I tried through file manager .. I can see the i go.exe but can't activate it .. I tried alao the apk nothing also

Somebody talled me to delete the i go primo icon that comes with screen.. Wich i dis and also nothing.. Im really disappointed .. Please anybody helpppppo me
[MTCB Android Head Units Q&A] Gatriel:
That was it. Thanks so much!
[MTCB Android Head Units Q&A] manicuspanicus:
Does the default behavior limits to just the app ? Cause I don't think it resumes let's say the last song that was playing. .. it starts over from the beginning I think...

[MTCB Android Head Units Q&A] agentdr8:
That is app-specific behavior. Say Poweramp is the last foreground app before you shutdown. Upon restart, Poweramp will reload, but it may or may not start over the previous song, depending on its settings regarding resuming.

Some media apps don't let you specify the behavior on restart/resume, and will just start the previous song over from the beginning. I believe the stock MTCMusic app is like this.
[MTCB Android Head Units Q&A] jleonar:
I would actually like that IF it stored the most recent foreground app and reopen it. For instance, as I mentioned my unit was opening the Nova zoomed out screen so I disabled it. That worked until the next time I turned off the car. During the next session, I had opened the settings dialog but it wasn't in the foreground. The app I always have in the foreground when turning off the car is either Google Play Music or Waze. Never has it opened them back up. So now, every time i start the car, it opens up the settings app. I can kill all the apps except Google Play Music then turn off the car. When I start it back, it will open up settings and nothing else.

So this morning, I setup tasker to kill everything at startup and go to home. Then start Google Play Music and Waze. I haven't had a chance to test it yet but I will see if it works this afternoon. Just don't see why I should need to use tasker to make sure **** doesn't open automatically in such odd ways. :)
[MTCB Android Head Units Q&A] R50Touareg:
Yes this is working but not all fields. I also had tourque working but the BT sender was and app was a little useless, I have Vag Com which gives mush better info and is more useful than watching a few gauges. All up I am well pleased , phone is my next issue then I can do a complete install. I have used OME GPS sender , and twin Farker for Radio . Also running a 64 Gig USB stick with movies which works well even though only 32 gig supported.

Agent 8 looks like you are a Motorcyclists also? Got what you said about the Phone app, so now my choice would be to have the app that came with the unit as I believe it is superior to the current. This might be an issue as the KK version may be included to fix issues and the JB app may not work? Can some one with wisdom on these things advise if I could go back to the OME phone app and keep the KK OS?

Thanks
[MTCB Android Head Units Q&A] theoreticaljerk:
I would love to have an option to disable opening the last app. I'd rather just choose what to open from the home screen since what I want to open will depend on what I'm doing.

Also, I was wondering, do we know the mechanics behind the screen dimming when the headlights are turned on? I know your app has some daemon that can do some brightness changes depending on time but I'm guessing since you went that route, there isn't a way to just tell the unit to go dimmer when it detects the headlights are on.

For everyone else, previously I'm pretty damn sure Google Play Music would restart the last song at the point in the song which I shut the car off. Now it starts from the beginning. On top of this, I noticed the progress/scrubber bar for the song inside GPM doesn't move. It just stays at the beginning. If you try to select a part of the song to jump to, the song just starts over from scratch.

Am I crazy and it's been like this the whole time or did Google maybe change something in an update that borked things? I'm on MCU 2.16 and Contou (probably remembering this name wrong) 4.4.2 v3.

Few pics with external MIC

As i mentioned in earlier posts, it was hard to use bluetooth for phone calls with the internal mic. i asked few members here on the board and i had a clear idea of what to do.

The final outcome was a lot better than what i was expecting, All i had to do was to remove the - and + to the internal mic and solder new wires for the external mic. installed a new female connector to the back of the unit and i used an old mic from my JVC unit that was laying around.

Internal mic was hard to remove, it was so epoxied that it was impossible to remove, so i just left it there

Here are few :D pictures of inside the unit.

JY unit wide open :highfive:

8" Android for Toyota camry

Brackets that hold the double din to climate control

JVC mic and male to female connector 3.5mm MONO

Read and black ( - and + ) for internal mic

A loose screw inside the unit, lol .... it belongs to the DVD drive bracket.

Broken piece that hold the ribbon to the board, it was very easy to break :confused:

Thats where the internal mic is located

Female connector at the back of the unit

The black wire MIC neg came out with no resistance barely holding to the board

The 3.5mm extension wire was too tick to solder to the board, i couldnt find an old headphone wires to use, so i cut a piece of an old gps wire and used it. was a lot easier to solder.

Wire soldered to the mic inputs on the board

I use some electrical tape (red) to hold the mic external wire to the unit while i solder it, had to be very carefull not to mess up anything else.
[MTCB Android Head Units Q&A] agentdr8:
Yep, I ride also. The JB BT app may or may not work on KK roms; I know there are some changes in the methods between the two, so chances are pretty slim I think.

---------- Post added at 05:49 PM ---------- Previous post was at 05:12 PM ----------

I'll see what can be done about it.

The MCU detects when +12V is on the illumination wire if it's directly connected, or via a CANBUS signal if there's an adapter. It then sends a broadcast intent with action com.microntek.light, and an integer extra of keyCode, which holds the value of what the backlight should be set to. Catching that intent wouldn't be difficult; but I think it would need to be a one or the other type setting. Either have dimming level controlled by the headlight on, or by the time of day.

@ agentdr8

is it possible to have the unit resuming always where it was, playing that last song?
[MTCB Android Head Units Q&A] agentdr8:
I'm not sure if the stock Music app can do that, which is why I use Poweramp.

Weird question...has anyone tried connecting a gopro through wireless to the headunit?

It'll be great if it works... Need something like that for offroading
[MTCB Android Head Units Q&A] theoreticaljerk:
Others can throw in their 2 cents...but I'd rather the unit just dim to some set level when the headlights come on. Only problem with this system right now is that the screen barely dims at all when the headlights are turned on.

I installed the Coudu's 4.4.4 V4.1 on my KGL for BMW E46 with 1024x600 screen.

Everything works well excepting:

- when I insert a usb stick or an sd card the unit show the BMW logo and it freezes, it keeps loading and nothing happens.

After I press the reset button everything works well but when I plug in another usb stick or sdcard, it hangs again until reset.

- I can't install iGo Primo or when I can it doesn't work

Hi agentdr8,

today I installed coudo's v4.1-update.img, the xposed framework and the newest beta of xposedmtc (1.3.2 I believe). Everything works fine, but automatically dimming now dims all the time.... it seams, that the calculation of sunset/sunrise fails: the times print out in the settings are always the actual, local time - I believe to remember :) that there were with KK4.4.2 the calculated times. Please, can you check, wether this issue is only with my HU? Don't hesitate to ask me, if you need any debug logs or informations.

Edit MCU / Layout

Dears, I upgraded to the latest 4.4.4 from boo.

So much better then even before, just a little problem on my back button.

My unit's original MCU was MTCB-KGL-V2.01, but I don't have it and overall, MCUs before 2.03 fail to be flashed on this 4.4.4.

This is not a big problem, anyway, is it possible to manually modify the "back" button action or the MCU?

Actually it runs with MTCB-KGL4-V2.09.

(I can't do without 3G - since my radio doesnt work)

Hello, same issue here. And BT OBD pairing of my Vgate obd doesn't work either. I entered Vgate as name of BT OBD adapter to pair. I tried with small and large caps, since I don't know if it's case sensitive. Works well on latest stable release 1.3.
[MTCB Android Head Units Q&A] maan2304:
I have _no_ problem with OBD and torque; pairing wih 2 klicks in bluetooth-settings and in torque settings search for the correct bluetooth device and go on. Evt. you have to set in the bluetooth-app the key to "1234" for the ODB-device to pair.
[MTCB Android Head Units Q&A] Tung_meister:
Well all the values are set to 14 which I don't get how that ties to a startup volume of 10? There's also no option to restore the previous value on boot.

Power amp it is then. By the way back view does not work for me. I guess it matters how it is wired. Mine is only powered when I put reverse.

When i wrote that and my friend replied i was on 4.2.2 and i thought he was right. Now after upgrading to 4.4.2. and now to 4.4.4 i have come to the conclusion that everything is a matter of software. I refuse to believe that poweramp has close to excellent sound on this unit while its radio sounds like..... i better not say. They both use the same hardware right? i believe in the future we will have a better radio app and the sound will improve.

Hi,

I have a problem with my Klyde unit, tried numerous things toget it running again but i cant get it to work.

The problem started when i was streaming music via A2DP from my phone to the unit and suddenly it gave the "shutting down" notification.

It powered down and never gave any sign of life after that :(

When i disconnect and connect the power again i get a beep, and via Canbus it show "WELCOME!!!" in the car's verhicle.

I can get into the recovery mode, and tried different mcu's and images (made for Klayde units offcourse)

Also connected 12v to the acc pin directly, that goes in the unit, i geuss this rules out the CANBUS decoder.

The only sign of life is the beep i get when i apply power :(

Does someone here have any suggestion, or an schematic of the PCB so i can measure it to find a fried component (i guess this is the problem)

The PCB has DK-HCT-MB 2014/06/24 REV-1.5 written on it.

No not me. Under power amp the sound is close to perfect. I have 2 amps in my car one 4 channels for the speakers and one for the sub. For configuration I turn off the sub from a knob it has , fix my speakers for mid and high and then use the basses knob to sort out the sub. Would be nice to have an option to control the sub from the unit but ..... hope dies last! [emoji12]

wifi connection drops?

Hello!

I have KGL unit withj 4.2.2 firmware (universal for toyota) 800x480

I share internet connection via my lumia 800 device or iphone (tested both) if i download larger amounts of data the wlan connection drops ( the HU wifi signal strenght bar dorps and goes away, but the shared connection sill works on other device. This happened with both devices so it must be some problem with the headunit.

How ever if use my huawei dongle directly with the device there is no problems, downloads do work as they should with no is no connection drops.

Any ideas to start figure out? Most strange thing is that for example it seems to affect larger than 3-4 Mb downloads, these and smaller usually go through easily? It happens even if i put my mobile data to slower speed...

Is it somehow alter the wifi settings, max speed etc to make it more stable?

Try turning off Wi-Fi optimization under advanced Wi-Fi menu.
[MTCB Android Head Units Q&A] agentdr8:
It should still update the times based on GPS location and configured timezone. The refresh only happens if the XMTC Service is running, and it isn't during a dimming period (so basically during the daylight hours). It also only updates after every 2 hours and if you've driven more than 25 miles. I can probably reduce those times and distances, for those that have very short trips during daylight hours so that it hits an update interval sooner.

Did you reboot after setting the OBD name preference and then try to pair? It shouldn't be case-sensitive, but I'll check the code to make sure. The stable release just overrides all BT adapter names, which apparently causes problems for phones that are paired after the preference is enabled (the system thinks the phone is a BT OBD adapter instead of a handsfree/headset device).

Yeah, I think the manual BackView won't work, as the MCU detects not only 12V on the reverse wire, but also the video signal change on the CAM IN composite line.

No, they dont use the same hardware, the radio is a separate chip.

The radio on my Klyde sounds good, some people have said the radio doesnt sound good, mostly KGL users, but also some KLD users, but some people have also said that the radio sounds much better in 4.4.4. Dont know if this is down to variable production quality or just the differences of opinion of what is good and bad of different users.

Poweramp WILL make a difference because it is run controlled by Android NOT by the MCU like the radio.

I've just stumbled across the android auto section in the xda forums. This thread is incredibly usefull but also one hell of a monsterous thread. I guess the huifei variants have reached a rather big userbase, so we should try to get a dedicated section in xda for android head units.

These days xda seems to have dedicated sections for all kinds of stuff, so why not android head units? Lots of device specific sections have a lot less activity than this thread alone.

Can the 4.2 BT Phone app be Installed in 4.4.4

Hi I am almost happy with my KGL. Have the 4.4.4_1 OS running and all seems stable. I would like to go back to the OME BT Phone app the one supplied with 4.4.4 is not the greatest for function. I have asked the question before but there seems to be no reliable answer as to weather this would work. Also if I was to try where would I find the OME app , and how hard would it be to interchange?

Poweramp is controlled by Android, BUT than the sound goes to the internal amplifier, what is controlled by the MCU. At least I believe this is how it works. So if the MCU/amplifier sounds awful everything does too.

Well, I tried 10 3G dongles, nothing to do.

It works only after a soft reset, then the system doesn't manage the dongle.

If connection drops or if the unit is rebooted it doesn't work anymore.

Many times it doesn't show the right cellular signal level.

Sometimes it doesn't bring up connection.

It's a disaster, any ideas?
