Questions

Long time reader, first time poster.just a few questions, I've been following the few different android head units for awhile, and this one seems to be the better of the 3, from my skimming. I only have a few questions:

1. Hows Torque been doing on these? anyone have screen shots? (This is my number one reason for wanting an android unit)

2. Who all uses Spotify? I read one user had some dislike due to the screen size, any one have a screen shot of this also?

3. Custom boot images possible?

4. How can I go about buying just one unit? I read somewhere, but forgot/confused it with the other units.

5. This unit supports a second camera correct? (I want backup, and 'pull in' cameras)

6. Ill think of more.

I know a few of these were answered, sorry, it was a long day of reading 600+ pages between the 3 units, so forgive me!

Heres a photo of the unit i just ordered, wonder if those are touch sensed buttons or if they are just fancy push buttons...

1: Look for screens on the internet, it looks pretty cool, cant help you with realtime data, i dont have it in my car yet.

Bluetooth (free version) will / seems to have some delay. Even though i have the bluetooth elm327 i am thinking of buying torgue.

And if its bad i will connect it via USB

2: I dont use spotify, but Xposed is the best solution to change DPI, it allows you to change per application, and that works perfectly, ive put some pics a couple of pages ago.

My example was for chrome, but i use it for multiple apps. Xposed needs root and by itself it does no harm, the appsettings module allows the DPI change per app

Together with this i totally have no regret 800x480 unit. I dont notice at all.

3. Yes, but make sure you can recover from bricks first. Since i am not sure yet how to connect to my PC in boot loader. (my unit Huifei KGS8401) does not have a front USB port. So i just installed the new firmware released by Huifei 2 weeks ago.

4. Huifei units can be purchased on alibaba, aliexpress, and android-carradio, i bought mine 2 weeks ago from alibaba Hanker yu. Shipped to Netherlands in 4 days.

About 570 Dollar with all options

5. a total of 3 for my unit, 1 Rearview cam, switches on reverse. 1 Video in, can be opened by AVIN app. and a DVR cam, thats a USB webcam option that can me mounted to the frontshield window as a dashcam. (auto record per day autostart is not available by default, it needs to be scripted)

6. Bring it on.

Tablet Talk did not work for me? I used it on wi fi but did not get sound? was able to download SMS. Also since I have two different Google accounts I had to purchase two lots of the app?

So I am still trying to go back to the JB version of the Phone app which IMO is way better than the 4.4.4 version !

---------- Post added at 09:43 PM ---------- Previous post was at 09:36 PM ----------

I only want to change the BT app back to the one that came with my unit. So how can I do this, first I need to find the app and then need to know how to load into the unit ? The current one as stated is quite hard to use as the interface is not so great. Phone is my only frustration now and it may turn out this is a hardware issue as far as performance goes.

---------- Post added at 09:54 PM ---------- Previous post was at 09:43 PM ----------

I have VW and found I had to work out which was AM and FM. The fakka needs to be powered and hooked up the correct way. I also had to trim the fittings to connect. I now get very good AM and FM , which I would say is as good as OME.
[MTCB Android Head Units Q&A] typos1:
Yes I know, but you must be on 4.4.2, because 4.4.4 has the same BT/phone app as 4.2.2.

On my Klyde everything works great with my phone and even though I ve not done any mods to the mics yet, with the external and internal mics connected, no one has complained about not being able to hear me on the phone either.
[MTCB Android Head Units Q&A] R50Touareg:
Has worked well for me. No issues to date. I do prefer the the better sound quality of Power Amp using my own files.
[MTCB Android Head Units Q&A] comptechltd:
typos1,

Which Klyde headunit do you have? I ask because I am expecting mine (actually a Pumpkin) very shortly and am still unsure what if anything I will loose when i put the rooted image on it. I am speaking of dialer, radio etc. I'm not sure if certain apps are proprietary or not.

[MTCB Android Head Units Q&A] R50Touareg:
I will check version but as far as I know I downloaded the latest version 4.4.4_1 and installed, The phone app is way different, I am running KGL unit which might explain the differences in what you are saying.
[MTCB Android Head Units Q&A] theoreticaljerk:
Good thing I found that app locker program. Car hit me today and I have to hand my car over to a collision shop. lol

Still, I logged off my Google account just in case. Haven't used the app locker long enough to trust it in the hands of someone else for weeks.
[MTCB Android Head Units Q&A] typos1:
You wont loose any apps.
[MTCB Android Head Units Q&A] mrbubba999:
Can you explain in a bit more detail how you got the good radio reception? It's really poor in my 2009 Skoda. I had to adjust one of the fakra cables to get it to connect, but I still get very few FM stations. Don't use AM, so not bothered about that.
[MTCB Android Head Units Q&A] typos1:
OK, both KGL and KLD had different BT apps in 4.2.2, but AFAIK they are the same in4.4.4. I remember the KGL 4.2.2 version had the phone keypad on its side, albeit with the numbers up the right way, so zero was in the middle row and to the right, it was stupid.
[MTCB Android Head Units Q&A] agentdr8:
This is an issue with the 4.4.4 roms; something appears to be blocking/consuming the BOOT_COMPLETED intent at startup. If you leave it on the launcher (Home) screen, the service starts as it should. But if there's a foreground app that gets restored on startup, those intents get blocked for some reason. I haven't figured out why or how to work around the problem, other than hitting the home button and let them startup.

You shouldn't have to purchase the app twice unless you're using different Gmail accounts on your headunit and phone. I use the same one on both, and can just reinstall the purchased app.

Also, make sure you configure the headunit to be the "tablet" in Tablet Talk settings. And it just initiates the call, which should transfer audio to your headunit via BT, just like if you were to make a call using the phone itself.
[MTCB Android Head Units Q&A] comptechltd:
Outside of texting from your head unit is there any other advantage of using tablet talk??

Steve
[MTCB Android Head Units Q&A] theoreticaljerk:
My 4.4.2 unit acts similarly though it doesn't matter if I'm on the home screen or not. Takes a good 15-20 seconds for PowerAmp to be ready once the screen becomes responsive. Had the same issue with Google Play Music.
[MTCB Android Head Units Q&A] agentdr8:
I use it for contact dialing since I don't have my phone paired with the headunit. I'm actually using a Parrot CK3000 for handsfree since the built-in BT of my GS is crap, even with the external mic modification.

The screen responsive issue at bootup is mostly resolved in 4.4.4. I was referring to apps/services that specifically catch the BOOT_COMPLETED intent that don't seem to be starting since 4.4.2 came out. The only ones I have control over are PowerampToast and XposedMTC, but neither receiver code has changed since 4.2, so it's likely something related to the newer Kitkat builds.
[MTCB Android Head Units Q&A] wokro:
Hello,

in my last Post #6012 I reported that I'm not satisfied in any of the versions from 4.4.2 to 4.4.4

What I did now was to combine the goodies of each version:

I took latest 4.2.2 JB System, removed most of the Apps and added the Apps from 4.4.4, like LauncherMTC3, MTCRadio3, BT App etc.

Now mostly everything works like I wanted: I've the new look and feel, in a more stable enviroment. iGO works now without any problems.

The only think I still miss is a well working AF function in the RadioApp. I went on the weekend 800km on the highway and the Radio was not able to track a nation wide station by RDS - AF. Always hat to do a new search.

As for the MTCmusic app is not really rich of functions I tried a lot other players and end up using Sony's latest walkman App. This was the best choice for me, easy to operate nice look and seems to work with a database as searches are extremely quick. It's offering Playlist support, albums, titles, Interprets, and many more. I can strongly recommend that app. Using it under JB 4.2.2 is OK, under 4.4.4 id did not work for me.

Hope someone finds that useful

OBD II adapter

Hi everyone

I am having a problem connecting HU to OBD II Bluetooth adapter — pairing appears to be working, and I even see a blue OBD icon in notification area, but Torque can't see it, and prompts me to pair the adapter from device settings, or even turn on bluetooth. What am I doing wrong?

I am using 1024x600 unit with Android 4.4.2, and ELM 327 adapter.

Thanks!
[MTCB Android Head Units Q&A] ultradj83:
Do not chance MCU on your device.

I did it with no backup and now I'm searching for the original KGL 2.01 because there are a lot a problem with new ones.

With 2.09 back button acts as gps button so there's no way to back.

Also, radio doesn't store stations and 3G is a shame.

If you haven't been updating yet could you send me your original MCU?

Thanks.
[MTCB Android Head Units Q&A] agentdr8:
It's a known-issue with the 4.4.2 roms. 4.4.4 fixes the BT OBD.

---------- Post added at 09:39 AM ---------- Previous post was at 09:36 AM ----------

Yep, I notice this behavior as well. I leave PowerAmp up when it shuts down and it's the first thing to show up on bootup. See if your headunit responds the same way as mine; if I hit the MENU hard button (which goes to Home), the services then start almost immediately.

I suppose it could be started via command line. Let me see if I can write up a script for you to test.
[MTCB Android Head Units Q&A] typos1:
Go to the KGL MCU downloads page, try all of the ones available and see which works best, it doesnt have to be 2.01.
[MTCB Android Head Units Q&A] kvantum:
There's a KGL 2.01 on the Russian huifei forum repository (along with what looks like every other possible version)

Try saving this as S99startstuff in /system/etc/init.d/, chmod 755, chown root.root:

#!/bin/sh

# start XMTC service
am broadcast -a com.dr8.xposedmtc.START_SERVICE

# start PAToast service
am broadcast -a com.dr8.poweramptoast.START_SERVICE

I had to update PowerampToast to include a broadcast receiver for that intent (along with STOP_SERVICE).

Also, relating to broadcast receivers and the intents they receive, this describes how they work and in what order (if any) they receive and process the intents. I don't believe BOOT_COMPLETED is sent as an ordered broadcast, which means any apps/services that hold the permission to RECEIVE_BOOT_COMPLETED will get it asynchronously.

No way, also because it seems impossible to revert to 2.02 or previous.

What MCU are you using actually?
[MTCB Android Head Units Q&A] ultradj83:
Usually on kitkat when a app crashes suddenly it's because it fails to write somewhere.

Can you run the latest Spotify and ES Explorer or they're crashing, too?

What about 3G connection? Is it stable and gets easily connected on every reboot?

Is OBDII working via Bluetooth?

You can flash ANY KGL MCU you like and flashing other KGL versions is no problem, many people have tried all sorts of combos, for instance a lot of VW group cars have fully working 2 way CAN Bus with 4.4.4 and MCU 1.77.

how to dump

Hello!

I have not updated as i know that it can cause problems i have not noticed such bad problems that need updatating...

How i can dump the mcu?

As far i have understand these pure KGL devices (with no numbers) are sort of universal models with no cabus or at least you should always match the number to avoid some strange problems (as you have had)

I have this device:

http://erisinwholesale.com/special-...droid-42-car-dvd-gps-corolla-ex-rav4-332.html

btw, could you test these, it reads that LZM SHOULD be same as KGL.

http://huifei.fs-fileserver.de/content/firmware/KGL-4.4.2_1024x600/

http://huifei.fs-fileserver.de/content/firmware/KGL-4.4.2_1024x600/软件升级说明.doc

You can find the PURE v2.08 LZM from here:

https://drive.google.com/folderview...haring&tid=0BxmzvLRI7-eNeVA2SWkwM1pLZ28#listv

If your unit is PURE KGL with no numbers it could work with your unit...

Please report test...

as this says:

that LZM = KGL?

It is the KGL v2.08 version without numbers so it SHOULD / COULD work.

BTW. HOW do i dump my original MCU?

This is just the action for an intent that I put into my apps. You can name them whatever you want. I don't know if Car Service has any broadcast receivers for starting & stopping the service.

No, I mean if you have a KGL you can use ANY KGL MCU !! From 1.68 all the way through to 2.12 or what ever the latest is !!

You mean in the downloads for the MCUs ? If yes then not every MCU is listed, just flash any MCU you like that matches your unit manufacter as per the guide on page 1.

It in system/priv-app or system/app, check where your current version is, back up and replace with the new version, set permissions to 644.

It is perfectly safe to update the MCU, it will not "cause problems" exactly - if some things do not work, then simply downgrade to the version you were on previously, often MCU updates enable more functionality, but not always, for instance 2 way CAN Bus only works with MCU 1.77 on KGLs with VW Group cars, despite it being an old version that did not enable 2 way CAN Bus on 4.2.2. You and ultradj83 are making too much of an issue out of this. Just try ANY MCU that matches the manufacturer of your unit and if some things dont work then experiment with any of the KGL MCUs in the googledrive section from 4pda.ru that was mentioned a few pages back.

No one knows how to dump the MCU AFAIK.

I flashed the KitKat 4.4.4 800x480 on my Eonon GA5153-Klyde available for the repository and found it it to work well but:

. Music App has no shuffle option (accessing local microSD card)

. Tried many music app from Play store and none can scan / read content on SD or USB storage

. Astro File manager can read and play music fine (videos too)

Could this strange behaviour be linked to your post about symlinks missing " added compatibility symlinks for storage mount points ..."

I'll try your next build and reflash if you reckon this will fix this problem
[MTCB Android Head Units Q&A] agentdr8:
It does seem to be inconsistent, which makes it that much harder to troubleshoot. I've increased the priority of my broadcast receivers, to see if that makes a difference (doubtful, but you never know). I'll do some testing later tonight and see if I can figure anything out.

4.4.4

I put it on my GS. The modded version has Japanese keyboard removed which is a pain.

Soon as I turned it on it had a ota update available for something or other. After installing it, it instantly had the GS error every three seconds.

Deleting gmscore did not fix it, but the google services fixer from google store did. It is up and stable now.

I will put a new launcher on it later. As I still think the KLD one is horrible. The screen is a little messed up on the launcher also 640x480 guessing I need to change the build.prop, but Just another launcher will more than likely fix it.

[MTCB Android Head Units Q&A] ptclabs:
4.4.4 found problems

1. Wifi is just plain weird. Yes optimization is turned off. Some times it starts when you turn on the car, sometimes it takes 5 mins even though it says it is connected. When it does that it also gets google search errors until it starts. Something just is not right.

2. When you restart it with the reboot command it dumps the saved radio stations, just a dpe 'dumb programming error" hopefully they will fix it in the next version to write to the database when you save stations not every time it shuts down.

3 getting the google now launcher on there was a pain, but it works, make sure to install google app first or it will mess up.

4. My reverse camera is now upside down, guessing there is a setting somewhere to change that, or at least I hope there is as it is a fixed angle camera.

5. same as everyone else, the way it loads some apps is just strange, sometimes 2 minutes after it is started. Something is not quite right with this version.

good things

iloveradio works perfect on this version, this is the first one it does since the very first version out. I likey. No crashing with it so far as all, well once the wifi starts working...
[MTCB Android Head Units Q&A] agentdr8:
I uploaded a new beta release of XposedMTC. It now has Screen Filter integration for those that want a darker screen during dimming periods, but the backlight just doesn't go dark enough. Make sure you install the latest version of Screen Filter and configure the filter however it suits your needs. I have mine adjusting the transparency to 145, which adds a nice translucent gray overlay at night time. Once the dimming period is over, it will send an intent to disable the filter.

If you find the filter useful, please stop by [MENTION=4272306]tony78960[/MENTION]'s thread and give him some kudos. Great module he's put together, and I definitely appreciate him adding intents so it can be a seamless transition when used in conjunction with XposedMTC.

I've also disabled the BackView activity for now until I can figure out if the video input is switchable on-demand.

---------- Post added at 11:20 PM ---------- Previous post was at 11:09 PM ----------

That's how the previous versions behaved as well if the headunit didn't properly shut down. Writing preferences out to file is an asynchronous task, and doesn't always happen immediately, so the info can get lost. I guess the mfg had expected this to happen, as they put in a method to reset the presets to predefined values if certain conditions had been met. It annoyed me as well, so I added preset restoring to XposedMTC.

I think under Driving Safety, there's a "Reversing x-mirror" or something like that. Try changing that preference.
[MTCB Android Head Units Q&A] BTW lover:
Can anyone give me a hint about volume control in these units? I'm desperately trying to get text to speech louder and possible decrease the volume of other sources while tts is running pretty much like the navigation app does with announcements.

I use an app called voice for notifications that reads aloud all incoming notifications. My plan is to push notifications from my phone to the headunit and have them speak aloud so there is no phone grabbing distraction ( also having a personal car jarvis is pretty cool) Voice for notification works great and I think pushbullet can handle the notification pushing but TTS is much too low in volume, especially with music playing and I just cant find a way to control TTS or actually any volume at all. I expirimented with tasker say command and pretty much all outputs availabe via tasker (media, notifications, etc) but I can't control any volume neither with tasker nor with 3rd party volume control apps from playstore.
