There were some changes in KK in the way storage is used, theres a fix for installing Tom Tom, not for this yet, I think you 2 are the first to report it, although I m not sure its relevant as the MCU controls the ipod app AFAIK, unless its shows it to Android as storage.
[MTCB Android Head Units Q&A] ftsur:
It's 100% relevant for those of us running a Rockbox'd iPod. The accessory implementation is not 100% the same in Rockbox as it is in the OEM Apple firmware. These head units won't control a Rockbox'd iPod. My work around is to get Power Amp to read the Rockbox'd iPod in disk mode to play the files. It presents itself as FAT32 external storage.

Read my last post again as I think you mis-understood it - when I said its not relevant, I was referring to whether the Android version is relevant to solving the problem as the MCU controls the ipod app.

I have installed your newest version with the standard launcher and am liking it so far. I am running into a few problems.

1) It wont allow me to update 'car service'. I try to install a new version and it will install but after the first reboot it goes back to the original version.

2) Poweramp Toast will not automatically start even though it is set to autostart.

Thanks,

So after spending a good part of the day in the car, I STILL have issues with the android mic input.

I cut the trace going to the C102 capacitor (Same component # on the KGL as the KLD, BTW) rather than removing it (since it was easier to get to a trace than the capacitor), and wired in another external mic port on the back.

Now I do, indeed, get android mic input, but unless I scream at it, or get right on top of the mic, nothing is heard.

I tried the microphone app suggested earlier, but it appears to have no effect at all on the gain levels.

I was on condu's 4.4.4, so I tried 4.4.2 and also MCU 2.08 (one at a time) and same thing noted. I even tried the Russian 4.4.4 and same thing.

Incidentally, the stock external mic connector that came on mine is the same way. i.e. works for android mic input and no longer works for BT.

So now my question is, those that have split the mic's and have voice search working, what rom are you on? What radio brand/MCU? Did you have to use the Mic Gain app?

What about a mini usb mic like this?

JY-C0344 - Pumpkin 8 Inch Flush Panel Pure Android 4.4 kitkat

I recently purchased this unit for my Jetta and I am very pleased with the install. I am having one issue and a hard time resolving, was wondering if anyone could assist with a few things i can't locate a solution to. I have yet to do any custom changes outside of a few additional apps.

#1 Has anyone had issues with MTCservice crashing in their units? It randomly happens during the day without any specific reason. I loose volume functions via Steering keys as well as Soft keys for Volume/Home until i do full reboot.

#2 Anyone have a source for a replacement MTC Music App that allows Folder view (and doesn't auto play when a HD is plugged in? Built in app seems to only show files and having thousands of songs on a HD can get a bit hectic!

#3 Is there anyway to link MTC steering controls to Spotify App while active?

Thank you in advance I will continue my search and hope to hear from someone who has more knowledge on this subject then I.

(if there is a more current thread specific for the JY units that I am not able to locate a redirect would be appreciated too)
[MTCB Android Head Units Q&A] typos1:
This thread is for all RK3066 based headunits, KGL, KLD, GS, JY, MD and YZ versions, there are too similar to have different threads for each.

The music app does allow folder view - I have all my music listed in artist folders, then album folders and it lists the folders, not annoyingly as artist/album, just all albums in seemingly random order, not ideal, but it IS folder view. Pretty sure 4.2.2, 4.4.2 and 4.4.4music apps did this also.

Not heard of MTC crashing before.

There are a couple of apps for SWC and other music apps - car service app and microntek headunit service app.
[MTCB Android Head Units Q&A] iletumi:
Yeah this version of the Music app has no sorting options at all I will look further into this once able later today. App installed just says "Music 1.0" and is a built in app.

The Car Service app I found on here solved my steering key issue with spotify.

I have no idea why mtcservice keeps crashing though I tried removing the handful of apps and still crashes. I may do a factory reset and see if it still continues.

Is there by chance an sdcard based root for these JY 4.4.4 units? There are a few fixes I'd like to apply via the MTC xposed module but so far any info on rooting that I've found has not worked.
[MTCB Android Head Units Q&A] agentdr8:
Nope, only flashing a pre-rooted rom will get you root for now.
[MTCB Android Head Units Q&A] typos1:
There are no sorting options, but all of the MTC music apps I ahve tried dispaly as folders, not files, unless youre talking about the AOSP music app, but although its on the device I dont know how to access it, but it IS there somewhere - Malaysk removes it from his ROM.

As agentdr8 says, you can only root KK ROMS using a pre-rooted update image.

Thanks again!
[MTCB Android Head Units Q&A] agentdr8:
I have not seen any JY images posted yet. If you've got one of these units, you might have some luck requesting an update.zip from the reseller/mfg you procured it from. Then that image could be pre-rooted.

But even if there are no JY-specific roms, the JY units will work just fine with any of the other roms available. Just make sure you don't flash a non-JY MCU image.
[MTCB Android Head Units Q&A] iletumi:
Good idea, contacted them to see what they say. They are pretty good in responding with support issues. If they offer one I'll be sure to provide the file for anyone to play with.

Hi! Now forum seems to be working normally, i can reply to your post.

Patch for next release is made by your mention in commit for next version.

About BOOT_COMPLETED event start - my service also catching the event android.intent.action.QUICKBOOT_POWERON - that is discovered in reverse-engineering of original apps, it seems to be rased earlier, isnt it? By the way, on 4pda at least 2 forum members reported me that service does not started in background - only after any key press on SWC.
[MTCB Android Head Units Q&A] agentdr8:
Interesting find. I thought only HTC was using that intent on their devices. At any rate, I've gone ahead and added it to XMTC and PAToast for upcoming releases.
[MTCB Android Head Units Q&A] Petrows:
At my headunit device (KLD) event BOOT_COMPLETED does not raised at all in some cases - for example when headunit is awaken from the sleep. Only from catching this event i had made the service started in "normal" mode with all unit power on cases. But in practice (as i had written in my previous post) not all power-on cases are catched, but i cant test all of them :(
[MTCB Android Head Units Q&A] typos1:
There was a link to some JY firmware a few days/few pages ago, but as agentdr8 said, the it only matters for the MCU, you can use ANY Android version on ANY unit.

Glad I found this post! Just what I needed.

---------- Post added at 11:22 PM ---------- Previous post was at 11:14 PM ----------

Do you or anyone know if the mtcservice communication is linked to the MCU in some way? The only issue I am currently having with any real concern which I posted about earlier is the service keeps crashing several times a day. I have the Dec 3 2014 version it came with and see the link I found is for Dec 8th release. Hoping it helps in some way.
[MTCB Android Head Units Q&A] agentdr8:
Are you referring to the MTC-Service app made by [MENTION=6114030]Petrows[/MENTION], or the MTCManager that's found in /system/priv-app? The latter does communicate with the MCU via serial.
[MTCB Android Head Units Q&A] typos1:

[MTCB Android Head Units Q&A] TooBusy:
3G

So, 3G seems to be a real challenge even for most experienced, and I am not one of them. The furthest I could get is using PPP Widget 2. I got Internet connection, but I could only use Browser, not Play Store, Wether Widget, etc. Not acceptable.

1. Can someone explain to me how 3G works on these units in relation to provider settings. Some settings seem to be common for most providers. Assuming that username and password are by default blank, and dial-in number is *99#, and assuming that authentication is attempted in order None -> PAP -> CHAP or similar, whichever works, there is still APN name which varies between providers. On a PC, without using the provider software, I had to enter the APN as an extra initialization command: at+cgdcont=1,"IP","internet". Otherwise, it wouldn't connect. So, what is the default APN that these head units are using? If it's, for example "internet", which might be most common, does that mean you can't use providers that require a different APN, for example "VirginBroadband"?

2. Has anyone got 3G dongle working with VirginBroadband?

3. Has anyone got 3G dongle working with Amaysim?

4. Has anyone got Huawei E160 (E160E, E160X) 3G dongle working with any provider?

By "working" I mean working reliably for at least a week without major issues.

I did. There were only two options and I tried them both. I also tried several times to change the band. I tried both US selection as well as a Russian one then switched back to US. The only thing that changed was I downgraded to Malayias 4.2.2 Rom because I was able to mount my 256gb Rockbox'd iPod with it (it's really awesome with Power Amp). But I'm unsure if the firmware change was the cause. I hadn't checked the radio in days and had been through a few firmwares trying to get the unit to mount the iPod. I've again tried different firmware and mcu's and the radio still won't work. I tested the blue wire on the back of the unit and it's turning 12v on and off with the radio app as it should.

I dont think anyone has these issues, be specific, what firmware, what unit, what dongle etc.

Anyway, most huawei dongles work, there is no setting up your internet connection,

a dongle is a standalone device, if its huawei and it works in a laptop or router then it will work in these units. apn etc are setup there and your provider needs to support your device. this has nothing to do with the unit

hello,

I saw both of the post,

- The first I realized that solves the problem by installing an app on your phone to control the sound from BT, (correct?)

- The second I realized that solves the problem by eliminating a capacitor (c 102) installed near the BT module (correct?)

** I opened my UH, but have not found the capacitor C102

** my UH has no external microphone, perhaps this is the motivation?

I found just the c32

** The WI FI has a single wire glued behind the display. massless and with a welding horrible.

*** (If you consider the whole canister ground, is a Faraday cage. Unsuitable to receive frequencies outside (do you agree?) Should bring the thread on the outside but with a shielded cable.

I still have serious problems with the sensitivity of the radio.

I have a picture on the capacitor C67 (which has the task to block any tension towards the tuner) and a diode D14, do not quite understand the usefulness, but perhaps to send a mass eventiali tensions and create a short film to protect the tuner.

someone can 'help me understand what I can do to improve the sensitivity?

Thanks for your attention

the internal microphone works well.

I recorded my voice and it felt good.

I think that the connection to the module from the Android system is wrong.

otherwise even the recording would have been bad.

the internal microphone is connected to the input Android.

the BT module, through c32 is connected to an output Android (who pours the audio captured by the microphone)

or on the same microphone, coupled in some way and then when you phone Android is bypassed?

in the second way, we can re-modulate the capacity so as to have an appropriate signal transfer.

what do you think?
