[MTCB Android Head Units Q&A] typos1:
That was me, as I said before, you really need a diversity tuner, or at the very least 2 aerials wired together into one, one at the front as high up as possible, one at the back as high up as possible.

Interesting you say that - I get the volume going up or down, or the unit un-muting itself aswell.

What makes you think its a "knob" issue ? I didnt consider it would be anything to do with the knobs at all, as I dont think theyre sensitive enough to be moved by vibrations or bumps, I was thinking it might be a dodgy connection on the SWC ground, or maybe GALA playing up.

Actually GALA doesnt appear to work at all on mine.

Are you 100% sure its the rotary controller/knob ?
[MTCB Android Head Units Q&A] agentdr8:
Nope, not 100% sure it's the knobs, but I don't have any SWC connected, or GALA installed. I though maybe the MCU is sending random garbage, but I can't imagine why it would start all of a sudden.

Have anyone used SPOTIFY?

I am a premium user and i want to have offline use with downloading lists.

Does anyone know where the songs are saved?

I will learn tomorrow when i will try it :)
[MTCB Android Head Units Q&A] 83martin83:
Really, I do not go out of my problem with the free hand and the address book.

At the beginning, although my N5 (MIUI) is connected, it can not import the phonebook in the app.

I bought and installed "Tablet Talk", the idea of replacing the original application, but can not pair my N5 to my radio (by the way, the developer proposes to refund the purchase even after 48 hours if it does not work, but he does not pay me ...).

I bought and installed "Bluetooth Phonebook" and there, great, I can import my phonebook. Except that it is useless because it is impossible for me to call from the phonebook. I click on the name and the phone icon and ... nothing happens.

I despair ... I feel like I have a problem with my BT car stereo, because even the ODBII dongle I have problems. It connects, but without asking the PIN. Torque and it does not connect.

Do you ideas?

hi,

For my part, I only use Google Play Music. But I copied all my music on the SD card.

Online or offline, it works well. It seems to me that there is no reason why it does not work the same way with SPOTIFY ...
[MTCB Android Head Units Q&A] Billkaza:
Did you try another phone to see if it also happens there?
[MTCB Android Head Units Q&A] 83martin83:
Indeed, it is not impossible that this is the MIUI ROM that is a problem. I will test with my wife's smartphone.

However, what about the problem with the ODBII? Bluetooth also.

Agentdr8 posted a solution a few pages back.

---------- Post added at 03:31 PM ---------- Previous post was at 03:29 PM ----------

From the people you bought your unit from - AFAIK the DVB-T modules are configured for the specific MCU type, ie KGL, KLD, RM, GS, JY etc.

You could get a DVB-T dongle for Android, though, but your ll get a poor signal when moving unless you get a diversity/dual tuner one, though and AFAIK there are none available for Android.
[MTCB Android Head Units Q&A] manicuspanicus:
My problem is that the seller doesn't have a clue he says there aren't any touch screen ones. I have a kgl unit.......
[MTCB Android Head Units Q&A] ErAzOr2k:
This is not the reason. I already tried to download on different PCs with different Browsers. I even tried to flash the old image. But the Result is the same.

[MTCB Android Head Units Q&A] 83martin83:
Yes, it is just the same with the previous XposedMTC module.

Unfortunately, it's the same.
[MTCB Android Head Units Q&A] agentdr8:
The BT override is only available in the latest experimental release. By default, Xposed Installer only shows you stable releases. You can change this preference either globally or per-module.
[MTCB Android Head Units Q&A] 83martin83:
Hou, hou! Then I'll look at it tomorrow morning. Here it is night in France. :victory:

Well, it's day! :o

But I have missed something, because I still can not connect my OBDII correctly.

At the time of the associate, he does not ask me for PIN ...
[MTCB Android Head Units Q&A] staneb:
You have TWRP recovery installed and are not using stock recovery which could be the reason for update not working correctly.

You have to enter PIN in the PIN field of the Bluetooth app before the pairing starts. The HU doesn't ask you for PIN.
[MTCB Android Head Units Q&A] 83martin83:
I have not explained well. I associate my OBDII in system preferences from android. The PIN is not asked.

Since my Nexus 5, this pin code is required.
[MTCB Android Head Units Q&A] staneb:
It's the same, you have a field for PIN in Settings also. Default PIN is 0000 and you can change it to whatever your OBD has.

If you open the BT app (MTCBluetooth), and hit Match, you should see a list of paired devices at the top. If your OBD adapter is properly paired, it should show up at the top in green. Pairing OBD adapters does not show the PIN prompt on these headunits.

If the adapter is listed and is green, you can then go to Torque, open settings->obd adapter settings, and select the OBD adapter's MAC address from the list of paired devices.

Hi all again!

On holidays in Russua uninstalled head unit out from the car and made some experiments on it.

- Made the full-silent volume ajust. No system Ui appears while the volume ajusted on speed

- Made the mute detection for service - volume ajust is skipped during mute on, speed change does not breaks the mute

- Made small options page (not complete for now, but usable)

- Not made: bluetooth calls via android phonebook. Idea was to catch the call from phonebook and startup the Micronteck bluetooth device for call (AT-Command AT-CZ on serial bluetooth device). I have found the proper calls and services, but there a low Android IPC mine knowledge for now :( I hope i will made it when uninstall headunit again.

Service app page: play.google.com/store/apps/details?id=com.petrows.mtcservice

Finally got my 4.4.2 unit. It is a KGL unit. with MCU of : MTCB-KGL4-V2.03 and Build #: rk3066-eng4.4.2 25092014.15.16:58

Couple of things that I do not understand.

1. While the screen resolution is 1024 x 600. They have the resolution set to 546 x 320 with a dpi of 300. So having the larger resolution does you know good on this device.

2. None of the standard root methods work on KitKat. Still digging in on how to root the device.

:)

Side Note. After turning off the car for 10 minutes, returning to it the unit booted right up like as if I just hit the power button on the front. Hopefully my battery wont be dead in the morning.
[MTCB Android Head Units Q&A] Warlord711:

The opening post is for rooting 4.2 units, as he said in his post, he has a 4.4 unit (the first person to get one I think) and the methods for 4.2 do not work. The shut down behaviour may also be different for the 4.4 units.

[MTCB Android Head Units Q&A] webdude12:
As I was the original one to find rooting options, I am familiar with all of them. None of the current apps work on 4.4.2.

As far as the restore power. It appears the time frame is somewhere between 2 hours and 7 hours of when the unit just deeps sleep. I can say the unit is powering off with key off as if it wasnt, I would be able to turn it back on. My guess is they added some type of capacitor to the unit, that is storing power and then powering off puts the unit in deep sleep until that capacitor runs out. As a side note, as I have not permanently mounted the unit the dash, I temporarily unplugged the power cable from the back of the unit this morning, and upon plugging back in, everything was still setup. Time, radio stations, etc... So this leads me to believe they have added some type of internal power source.

FYI I have an Audi A4, so I do have Canbus. But its not the case the unit is staying powered, as this morning it did a full boot, but a couple hours later I got back in the car and the unit woke right up.
[MTCB Android Head Units Q&A] agentdr8:
Very cool. I thought about building the same, but externally for my GS. I wonder what size cap they use to keep it in "low-power" mode so long. Also, I wonder if they've integrated any sort of voltage detection, so that it properly shuts down when the cap starts to run out, or if it just cuts the power hard to the unit.

System speakers

Hy guys,

I have HU for one month, bought it from pumpikin Germany. It is GS unit upgrade on 2.02. I like the gadget, but some things are not working as it should. I read most all similar threads, but I didnt find the solution for my problem, so can anyone help me:

The boadcasting music from radio, cd, GPS, is fine it is playing on all speakers in my car, but when I swich to SD, USB or through BT only right side of speakers are active. I instaled a few aplications and after upgrading there is no change.

Thank you
[MTCB Android Head Units Q&A] 1-2-Hak:
I actually think the shut off time is via MCU not by capacitor. If you go into recovery mode (which doesnt use MCU) the unit stays on with or without acc power. So I think the control in the MCU uses the acc as an indicator only when to turn on unit and remove power.

Bose question... When you use rca line out do you have tic tic noise from the speakers? When i use speaker out to rca (through a line driver) the sound is fine.. When i use Klyde rca pre out to the Bose amplifier i have a tic tic sound [emoji53]

Apart from that i love the unit!!

Nova launcher with live wallpaper, spotify,poweramp, torque with widgets on the home screens.

Great sound (like my old pioneer avh2400bt).

Bluetooth sound excellent, people here me clear but a bit low in volume.

Before rooting this think with Baidu master, steering wheel controls worked with poweramp without installing anything.

After I installed carservice and xposedmtc(thanks guys for the great work!!) i had to choose which application i used for music.

I would like an option for the swc to work every time with the app that is working that time. Now if i use spotify and have poweramp as default then if i use next song steering wheel button then poweramp starts to play.. Is it possible the command to go to the player that is playing that moment?

Also can i change the default gps button to sygic?

Just spotted a Witson unit that mentions that for CAN-Bus/digital SWC "a Pioneer patch lead is required", thought this may help some people who are having problems with SWC, particularly on CAN-Bus cars.

I ve often wondered which manufacturer's protocol these units use for SWC or whether they use their own specific one, knowing that (RoadMasters at least) use Pioneer may help with other things - it could possibly help get dual channel CAN-bus working ?

---------- Post added at 01:33 PM ---------- Previous post was at 01:03 PM ----------

I tried using the RCA outs on my Alfa with Bose, these units have 3V on the RCA outputs and the Bose system requires at least 4V for decent volume, sure enough, the volume was not high enough for driving at 50mph +.

Also the sound was a bit dull, I didnt get any tic tic sounds or ground loop problems though.

Changing the volume levels in the factory settings made no difference as the internal amp was being by-passed.

So I bought a line level converter specifically for the Alfa Bose system, the volume was also a bit low, but adjusting it in factory settings works now cos the internal amp isnt being bypassed.

The sound quality is also much, much better than it was using the RCAs. Using RCAs is generally regarded to be better than using speaker outs, but in this case its the other way round, I can only assume its because the Bose amp is designed to take a signal that has been converted from speaker outs via a line level converter (the standard headunits are connected this way, at least on Alfas - they know when the Bose system is connected and drop the output to a low level signal).
