Unbelievable but true. I connected with all possible vendors, and the official dealer of KGL, but none of them meet my messages. Just I want to buy this f...n RK3066 SoM card, but none of them appears interest.I don't know what to do. Can anybody help? Yesterday disassembled the device and made a picture of the card in question. Please give suggestions on how to proceed.

While the FM reception in my unit is fine, it's just the lack of robust AF that drives me nuts.

I suspect it's just a badly coded radio app.

I wonder if it's possible to decompile the stock radio app and get a look at the code?

On the other hand - Dab functionality would be very cool.....

my reception is ok, but less good as my old headunit (with the same antenna) and it doesn't AF as it should.

considering DAB+, the following video demonstrates several apps that can operate DAB+ tuners, also WaveSink Pro has a nice polished interface and stored presets etc:

No, the RK3066 and RK3188 are not 5.0 compatible.

Its just a case of buying the appropriate ribbon connector to fit it.

I think they may be just saying it - AFAIK both the RK3066 and the RK3188 are not 5.0 compatible - at least thats what I ve read, although a google reveals that someone has got an RK3188 to boot into 5.0, but not everything works. The RK3288 however is, I think that maybe the next upgrade, but as the RK3188s have only just come out, it may be a while.

Glad youve got it working. You can only adjust the sound in BT, radio etc by using the built in equaliser, you can turn off the built in one by putting it in "flat".

Yes, its been tried before, about a year ago, thread search "wavesink". For TV, though youd need a diveristy tuner really and there are none for Android. There is also the 2 Dension products that have DAB/DAB+

Forget about vendors and dealers - contact the factories as DSA did and yourll get your SoM.

It has been decoded before, someone modified the programme types as they were wrong, I m sure someone who knows what they are doing could also make the AF work. Also it may be worth a lot of us emailing the factories and asking them to make it work properly.

[MTCB Android Head Units Q&A] koimr:
I'd love something like this as well (my problem is more the other way - light-skinned apps are sometimes hard to read due to the angle of my head unit in my dash).

From my understanding this is something that would need to be handled within the kernel and ours don't have that ability. Someone would need to create a custom kernel for our units and I don't think that's likely as there are no sources available (or at least I haven't seen one/any). Even then I am not sure if it's possible as I've never done any kernel programming myself and there is probably more to the story such as screen driver capabilities, etc.

There are some apps in the Play Store that do claim to be able to adjust Contrast but from what I've found with them is that they generally put a filter over the entire screen which will compromise your brightness - however, this might work in your case so give them a shot. And to really be helpful, post back with your results. :)

You can try installing build prop editor. http://android.stackexchange.com/qu...n-brightness-below-the-minimum-without-an-app

That works for brightness but not for contrast which is the issue that we were talking about (grays being indistinguishable from blacks, same with whites and light grays).
[MTCB Android Head Units Q&A] typos1:
Sorry, my mistake, the JY RK3188 is not available yet. The only real difference is the launcher, so you could download the KLD image and extract it from there, then replace the KLD launcher with it.

Other than hardware mod, I dont see how you can adjust contrast if the rom does not support it.

Sorry guys, I've been kept out of the forum by real life (work, my 1 yo son, ...)

But anyway, here are v4.3 image for 800x480 and 1024x600 in KLD and JY variant, based on latest releases (150416 for KLD, 150415 for JY).

Same features as above plus some new tweaks:

MMM_N.N.N_XRESxYRES_yymmdd_rooted_light_reparted_init.d_recoem_vV:

removed apks:

- MTCoem apk removed (no more apks to install in oem part)

updated apks:

- Google Play Store (updated to latest version)

- Google Play Services (updated to latest version)

modded:

- Xposed app_process binary added (only binary you need to install Xposed installer for Xposed to work but if you restore data with TWRP you're good to go no need to re-run the installer!)

- Early start of mtcservice by [MENTION=6114030]Petrows[/MENTION] (only starts the service if it is installed or if data are restored with TWRP)

- oem partition now holds standard and TWRP recovery images (mounted on /mnt/oem in Android and mountable on /oem in TWRP)

Updated TWRP image

- fstab updated to make oem partition mountable

So now to flash recoveries when in Android type flash_image recovery /mnt/oem/twrp.img or flash_image recovery /mnt/oem/recovery.img. And to flash standard recovery when in TWRP (after mounting oem from mount menu) flash_image recovery /oem/recovery.img.

Download latest versions HERE

Happy flashing!:laugh:

What's the difference between latest rk3066 800x480 KLD vs JY ?
[MTCB Android Head Units Q&A] Enc0der:
I gave up on PlayerPro for now because JetAudio simply looks much better IMO...

However I have another issue with it - the hard buttons (and SWC) sometimes skip multiple tracks - sometimes 2 tracks, sometimes even more (3-4 tracks at once).. Occasionally it even starts to loop like crazy without stopping..

I disabled the "Headunit" app just to be sure it doesn't get multiple commands from both Headunit and XposedMTC, but it didn't help.

Do you have any experience with JetAudio (Plus) ?

---------- Post added at 12:17 PM ---------- Previous post was at 12:08 PM ----------

I'll take a look at JetAudio to see which intents are being used. As for the multi-press issue, it's either a combination a multiple apps trying to send the same intents, or it's buffering due to the slow start up of the on_boot services. I only use XMTC on my GS and don't have the multi-press issue, but I did when I had Car Service also installed.

Just picked up a Eonon G2110ZV headunit. Manufacture date says 04/09/2015. MCU is MTCB-KLD-V2.41. Android is 4.4.4_02022015.

I want to root it, so if I read correctly, I can installed the pre-rooted image from Coudu? Latest I see is KLD_4.4.4_800x480_150416_rooted_light_reparted_init.d_recoem_v4.3. Correct?

Latest MCU I see is 2.49 as well. So just put the mcu.img and update.img on root of GPS card and let it do it's thing?

I am trying to install dedicated offline Navi (either Sygic, Here, or TomTom) and they all want to install to the internal NAND flash. Any way to switch these around so I can install all apps to my 32GB GPS microSD?
[MTCB Android Head Units Q&A] coudu:
contacts numbers must use the same "format" as your phone displays a number when someone calls you eg. international or national format and with or without spaces.

If your phone displays the caller number in international format without spaces then all your contacts should be recorded this way.

You can use this app on your phone to change all your contacts numbers format in one click and then resync your contact with your headunit.
[MTCB Android Head Units Q&A] zorantoma:
Thank you for the hint,but i was the one who noticed this in the begining and belive me,i tried everithing.That is why i have the same number saved twice(one international and one local),becouse my provider cant decide which extension to use . The wierd part is whit the newes kyd and jy firmware bluetooth gets shut down on the unit when i try to sync contacts.i have to use bluetooth phonebook from playstore on my phone and set it not to sync contacts photos. The the syncronizacion gest thru. I then have names everywhere exept in the litle window at the botton of the screen.

[MTCB Android Head Units Q&A] Niolin:
Dear God, what a thread.

So, I've tried reading through this thread. Really, I have. I've tried searching, too, but it's just...it's all just a jumble, and I'm afraid I have to do the awful thing of just asking someone to straight up answer some questions (which have, for sure, been answered before).

We really need a headunit section. Geeze.

Anyways, I recently purchased & installed a head unit. I tried posting a link, but I'm too new; it's on the AutoPumpkin site with SKU KD-C0234. It works pretty well overall, but there's some things that I would like to change about its behavior, and I believe I am posting in the right place for the help I need...if not please point me in the right direction.

The stock navigation application is pretty much crap. I've tried using Google Maps and Waze, and they work fine (using my phone hotspot for data), but they are so quiet compared to the radio that I can't make out the turn-by-turn. Is there any way to auto-attenuate the radio/bluetooth when the Android audio is playing the way the stock nav app does?

Directly related to that question, I can't find any way to re-map the 'nav' button from the stock application. I want it to bring up Waze when I hit that hardware key, not the iGO app. I've seen reference in here to a 'general' section in the device's settings where this should be located, but I don't see that anywhere.

Are there any apps that would allow me to set up different equalizer settings for different radio stations or audio inputs? I tend to go between alternative rock and sports radio, and they are literally exactly the opposite settings for equalizer controls. Having to go all the way into the amplifiers settings each time I switch stations is not a very good solution.

Finally, bootup time. This thing takes forever to boot. I can turn it off while I'm driving and when I turn it back on, it's nearly instant, so it does seem to have some kind of standby mode. Should I rewire this device to be always-on instead of acc-switched and just remember to turn it off when I leave the car, or does it draw crazy power in 'standby' mode and really needs to fully shut down?

Someone please tell me where I can go to respectfully request a head unit section so we can pare this thread down a notch..., and, thanks to whoever answers me for your patience.
[MTCB Android Head Units Q&A] agentdr8:
Settings->GPS->GPS Application -- maps this app to the Nav button, in addition to defining which nav app participates in audio switching. Make sure you set the audio settings to Mixing, and adjust the amount positive or negative to your liking.

Nope. The MTC-based apps all use the stock EQ settings. The exception is MTC Music and MTC Movie/Video, which are android apps that can utilize ViperFX.

Covered many times in this thread. It's not advised to wire it to battery constant, as you'll end up with a dead battery after about a day. The standby isn't for fast (re)boot times, but to give android enough time to shut down all apps and services, prior to having power removed. There are alternative solutions posted, one of which keeps the headunit powered all the time using a micro 12V UPS, which will auto-shutdown if the car's battery starts to dip too low. There's also plenty of posts regarding temporary power-loss situations, such as when you're cranking the vehicle (say after a fuel fillup).

And lastly, we've pleaded our case to the XDA mods repeatedly regarding separate headunit sub-forums, but they don't seem interested in creating any, and probably won't until more Android Auto headunits hit the market. That still leaves this group in the lurch though.
[MTCB Android Head Units Q&A] Niolin:
I could kiss you, or at least ask my wife to kiss you for me. Thanks for taking the time despite that these things were covered already; I'm sure you can understand that this thread is a little overwhelming to someone coming into it on page one thousand, one hundred and ninety. So now I'm just stuck with listening to sports radio with a lot of bass and waiting almost a minute for anything from my stereo when I start the car; not that big of a deal, all things considered.

Thank you again.
[MTCB Android Head Units Q&A] aigochamaloh:
Seriously this thread is a mess. Questions just get lost in here, like mine haha.
[MTCB Android Head Units Q&A] agentdr8:
If you're still on a 4.2.2 rom, I highly suggest you upgrade to one of the 4.4.4 roms. They improve boot-times (at least the android portion), and are more fluid and usable. Information for that process is all laid out on the first post of this massive thread. I think the average cold boot to having audio come out should be around 24-36 seconds, depending on if you're using early boot mods like the install-recovery.sh script (also covered somewhere in the middle of this thread).

If you've got a few days to burn, I recommend reading the thread from page 1. That's what I did when I first got my KGL (although it was only around ~600 pages or so back then).

Another issue with JetAudio - audio focus...

It seems that JetAudio will always PAUSE the song when it losses audio focus (a.k.a GPS announcements etc').

I HAVE "MIXING" ENABLED, and it does work perfectly with the built-in apps like Radio and also with 3rd party apps like PowerAmp (when it's set to not pause of audio focus lost) and PlayerPro.

Is there a way to "trick" JetAudio into not-knowing that it is losing audio focus, so that the mixing feature will work as expected?

thanks
[MTCB Android Head Units Q&A] agentdr8:
Not that I know of. It's something that JetAudio should implement (like how PA has implemented it).

Confirmed on way home. Paid version of JetAudio playing. Switched to IGO and set directions to home.

Voice over cuts in then back to full volume music. No pausing.

Also confirming that on my Pumpkin KLD unit holding down the power button turns display off after 2 seconds. Keep holding for another 4 or 5 and it double beeps and boots into recovery.

By the way. Pumpkin has started selling the quad core units.

Currently the BMW E46 seems first for them.

Keymap, Reverse camera grid lines, Bluetooth, screen cast

1) REVERSE CAMERA GRID LINES: YES I have been through every last setting including factory settings.

Considering the reverse camera works before the android unit loads it should be handled by the MCU or actual prints on the camera lens.

so if anyone has any idea how to turn on the grid lines please let me know.

2) BLUETOOTH app does 2 things,

a. connect phone calls

b. stream audio via BT.

I do not care for the Audio stream when I am listening to radio I just want to make a call and after the call continue the radio app.

If I turn on the Bluetooth app the Radio app is Killed and will not turn on again after the phone call is finished.
