Another question.

I have a skoda octavia with builtint bluetooth which works on the Matrix display behind my steering wheel. If i connect my phone to this device the sound isnt going anywhere so i cant manage the sound of the builtin bluetooth to go trough my speakers. I would prefer to use this for phone functionality instead of the HU because the sounds (specially the mic) is far superior also the steer controls / addressbook works just so much easier.
[MTCB Android Head Units Q&A] typos1:
You would have to find the audio outs on your OEM BT module and connect them to the audio in on the head unit.

It may be better to try and connect your car's mic to the mic in of the head unit, but I agree about the phonebook - the up/down buttons do not work when you are in it, which is stupid, meaning you have to take your hands off the wheel, defeating the object of having SWC. I ve asked agentdr8 about this he said it may be possible to implement, I m no dev though so I dont know how to do it and I guess agentdr8 is a) busy and b) doesnt especially need this function enough to develop it- i dont think he has SWC, actually, so it (understandably) wouldnt be a priority for hi to do.
[MTCB Android Head Units Q&A] grimpy:
Thanks for the info, I would have to sacrifice the AVIN for this then cause its the only input of the HU, which also means I have to manully switch to the input whenver an incomming call happens.

I've read that switching the mics isnt an option since the builtin one is wired to the builtin blueoth + its a active one which use some kind of different signaling (requires power afaik)

Have you a Idea ?

I use Install-recovery.sh with only MTCservive for the boot and it's always long... for MTCservice, for exemple Viper4Android is always load before MTCservice ????

In my install-recovery I have only the mod for tomtom before the launch for MTCservice.

Voice search

I have a KLD unit which is working very well thanks to everyone's work on this post. I have successfully upgraded the os with a rooted 4.4.4 from the first post and Spotify works great as my music app. I have even added an external WiFi socket to enhance the signal so thanks everyone.

However when I install the latest update for google search, the google app crashes when attempting a voice search. If I uninstall the update the voice search works perfectly again. Does anyone know why this might be? Or how to troubleshoot the issue. I see others have this problem but there has been no solution, unless I have missed it.

Cheers all

Hi all Noob here

Just took delivery of my new unit details are:

KLD-s7

Details:

Dual core rockall 3066

8GB internal

Ipod control

Dual USB inputs (max 32GB) (Cabled to Rear)

Dual micro SD (max 32GB) (Front)

Canbus module for Seat Ibiza

DVD

MCU 2.3

Android 4.4.4

Unit has been installed in car and basic functions work, but I have some issues and would like to know if these are known or should I open dispute with supplier. I've started going through this thread but I will never get from start to finish within the reaming dispute time!

Unit is now hooked up on bench for ease of testing.

Issues:

1) Radio sound quality is very bad. FM signals are there but very noisy, AM can't find any station. I have reverted to stock unit and sound is perfect on both. I am aware of issues with active aerials which I have but the adaptor supplied seems to have no effect with or without the aerial power connected. I have ordered another aerial adaptor to see if this makes any difference. This is a big deal for me as I want to list to AM.

2) No auto brightness control for screen day/night operation.

3) The supplied IGO sat nav software is unusable as the buttons are off the bottom of the screen, although it does appear to function correctly.

4) Google Now crashes as soon as a voice command is recognised. This is another big deal as I want to be able to speak to text, dial numbers etc

5) Rear camera works fine and is active when in reverse via canbus. Tried an old pc USB webcam to use as front camera but its not detected. :(

Questions:

1) Anyone else have the same issues with Radio reception?

2) Is retro fitting a DVB-T board an option to improve radio quality (some AM stations are available via DVB-T)

3) Seen plenty of conversation so far on auto brightness, can someone please point me to a post which will work on my unit? Do I need to root?

4) What's the issue with Google Talk/Now its fine on my phone so not the setup?

5) can I get a USB camera to be recognised or do I need to go via the AUX In video

Any help in answering one or more of these would be great.

Thanks,

W

Some problems on KGL4

Dear community,

First, i wish to thanks you all for all your work!

i have found many answers to many question in this thread!

My unit is an MTCB-KGL4 V2.08, model S07, on android 4.4.4

i have flashed the coudu's rom 4.4.4

But i have some problems:

1 - no SMS send/received, even with Go sms. (i have a working 3G key, but need to power the USB to prevent the 3g connection vanishing.)

I don't have anything about them in system menu, and so i can't select go SMS as default app. also no sms in hangout, so i think there is some android services missing. any clues on that?

2 - in factory menu, i have tried different settings for the CAN Bus (all of that have relation with VW group, like Seat, VW, Audi, Skoda,....), but none of them work.

My car is an Audi A3 2006, and the CAN Bus box behind the car radio work (i can use steering wheel buttons), but i have nothing displaying on the OBD.

Is that normal? may i have to unplug the CAN Bus box, and connect key1 and key 2 cables to the CAN Bus?

3 - Poweramp soung level do not goes low when Waze spoke.

From what i have found here, it seem that poweramp have some specific way to output the audio.

Does anyone know a good player like poweramp (with album/artist/... , but no need of equalizer or anythings like that) that support the volume change when GPS app "speak"?

4 - missing some setting in system menu, like "network connection settings", data used. All the network part, except wifi, bluetooth, and apn...

so this is all for the moment, for other questions, i have to search before asking... ;)

Thanks!

I have a problem with my subwoofer. Everytime i switch on or off the radio there is a loud plonk coming out of my subwoofer. It does it too if i switch between the radio dvd and media app. With my old android radio from icartech it doesnt do that. Is there a solution for it?
[MTCB Android Head Units Q&A] zapan999:
Hi Wagy,

for the radio problem, did you have an VAG group car, like Audi, VW, Skoda, ...?

for my audi, i need to buy a specific antenna adapter, cause the antenna need to be powered!

i don't know i is the same thing on other car brand.

Just seen that you have an seat , so you are in this case i think...

verify if your KLD-s7 have an "ANT C" cable not wired. if yes, connect it to +12v. it will power the antenna of the car. plug to normal antenna cable (if you have one ;) ), not the Fakra one (depend on your car, the fakra is used for AM antenna, or GPS antenna...)

if not, you should get an adapter cable (like 15-20$ the OEM), like this one: 1H0051551A (vagparts.2am.fi/images/1H0051551A_pic_01.jpg)

. please be sure that you have a antenna plug "extender" (image.made-in-china.com/4f0j00GCrTJBYnZlUm/Male-Car-Radio-ISO-Plug-to-DIN-Aerial-Antenna-Plug-Adapter-Connectors.jpg)

---------- Post added at 09:33 PM ---------- Previous post was at 09:24 PM ----------

just haven't seen that you look for AM, not FM...

please take your old car radio, and check what plug is used for before buying the adapter.

please let us know

help needed

Can you attach a photo of it? I owned 2011 CR_Z

I'm confused.
[MTCB Android Head Units Q&A] Wagy:
Hi zapan999,

Thanks for the response

Yes the car is Seat and has Fakra connector, I tried the ISO/Fakra adaptor that was supplied with unit and reception was bad, connecting Ant+ (blue) cable from HU to adaptor makes no difference to signal especially AM. I also noticed that the supplied adaptor is plastic, I would have thought that if we are using Radio Frequency everything should be shielded so should have a metal case? I have ordered an alternative (ebay.co.uk/itm/291403825417) which appears to be metal body and does not require extender. I will post back once it arrives.
[MTCB Android Head Units Q&A] OBeerWANKenobi:
Ugh, I finally made it through this thread. LOL

Hi all,

I just received my head unit yesterday.

It's KLD-V2.3 and running Android 4.4.4 from the factory.

Since there doesn't seem to be any step by step instructions on how to install a pre-rooted ROM, I'm a little unsure on exactly how to do it. Would someone mind telling me if the steps below seem correct?

this is what I've gathered throughout the thread:

Format a MicroSD card to FAT32

Grab Coudu's 4.4.4 v4.2, the one I found is named: KLD_4.4.4_800x480_150113_rooted_light_reparted_init.d_v4.2 (supposedly the most "stock-like" ROM right?)

Unzip the above and move update.img to the root of the SD Card

Install SD card in MAP/GPS slot.

Fire up the unit

It should then run

Is that correct?

Is there an easy way to go back to stock with this method if I encounter any problems?

Thanks for any help!
[MTCB Android Head Units Q&A] zapan999:
Wagy,

shielded or not, just on the connector should not make a big difference. for what i know, the +12 volt for powering the antenna come from the FM DIN antenna plug... maybe also from AM fakra plug, but not sure.

do you have one DIN and one fakra, or two fakra?

---------- Post added at 10:16 PM ---------- Previous post was at 10:08 PM ----------

OBeerWANKenobi,

i've do it last week, this is the right process.

when the unit boot, it could take some time to detect the upgrade, and ask you to do it. (maybe 1 minute max)

I dont know where you read that, there are many posts in this thread about how to add an external mic, there is no problem adding one.

---------- Post added at 11:13 PM ---------- Previous post was at 11:05 PM ----------

Rockall ????? Rockchip, I think you mean ! You also mean KLD S07.

There is no max for USB input, SD cards have have a max of 2Tb if re-formatted in FAT32.

You most probably have an antenna booster in your antenna which the OEM headunit fed with power, you need a booster power injector to restore this and your signal, google or ebay it, or use the thread search function.

(EDIT: I see from a later post you have ordered one already, this is the correct one AFAIK, however some VW Group cars are slightly different to other manufacturers (twin fakras for instance), so I would google how to power the OEM antenna booster on VW cars to be sure, try VW forums etc. These headunits, like most aftermarket headunits, do not inject power into the antenna line for OEM antenna boosters)

Google voice search seems to be a bug in the latest update, simply use the previous version.

I too had the idea of DVB-T for radio (DAB is an old format with very,very low audio quality, worse than FM, radio via DVB-T is better quality), but you will need a diversity/dual tuner DVB-T module for decent reception in car.

---------- Post added at 11:19 PM ---------- Previous post was at 11:13 PM ----------

How to update is on the first page, it could not be any easier - stick the update on the SD card (GPS one), wait til the head unit asks if you want to update, click "ok" and it will update. Sometimes it fails the first time but works on the second, on rare occasions it doesnt work, in which case go into recovery and do it from there. To go back to stock do the exact same thing with a stock image.
[MTCB Android Head Units Q&A] OBeerWANKenobi:
Thanks guys,

I swear that I read the first page 20 times and never found the step by step......I just looked again and found it. doh! I guess I missed one of the "click to show content" buttons.

Anyway, I was able to get through the update and I'm running Codu's ROM.

So far the only thing that isn't as expected is that it wiped igo and my NAV button doesn't do anything anymore (understandably if igo is gone) I'm guessing I just have to install a NAV program and then go to GPS settings and select it. Is that about right?

Other than that, looks good!

Great job on the RK3066 HeadUnit service update. I was able to make a call from the contacts list for the first time.

I am using Coudu's 4.4.4 v4.2 rom and MCU V2.22 and during the call my screen went black and stayed that way until I tuned off the car and back on. Home and Back buttons did nothing. I have not tried it again yet. This might be a new install one time thing, but thought I would mention it.

Hello bluetooth

Hey I have been gone taking java classes for a few months. happy to see everyone is still around.

I think I know enough java now to start on the multiple phone bluetooth problem now, unless someone else already has?

While I have not taken the android java class yet I have take basic intermediate and am now starting advanced. I think the theory would be the same, but would still love some help of some of the old dogs on here.

I basically plan to override the java connection commands. There already is a command to get the list of bluetooth users. then just make a simple algorythem to check if connected, if not move next, if still not sleep 600 and try again

It will be my first android app, so I am bound to screw something up, will need some help getting it signed also.

It does have to do with the head unit - a lot of cars are not fully supported on the CAN Bus side and things are not displayed on the dash because of this.
[MTCB Android Head Units Q&A] devilsoft:
If you reffer to the info sent by HeadUnit to dash screen, then you're right, but [MENTION=347858]acca[/MENTION] said that the language screen has no french, so I suppose he's reffering to the Car native menu, which has nothing to do with Headunit. Head unit just send the command to CANBUS to display the settings screen. At least, that's what it does to my car.
[MTCB Android Head Units Q&A] typos1:
These headunits are modified tablets and do not have the standard Android SMS services.

Are you getting CAN Bus and OBD confused ? They are totally different things, if youve tried all the CAN Bus settings and nothing is shown on your dash display (MFD in VW speak) then there is not much we can do, I am pretty sure there is support for the Audi A3 (pakidermo has one), I think its only basic support though. Thats assuming you menat MFD when you said OBD, of course you ma have meant an OBD app for an OBD device ?

I d recommend the built in Music player, I ve not heard of the problems with Poweramp that youre having before.

There is an app you can install that gives access to network settings, its called "Mobile Network Settings" I think.

[MTCB Android Head Units Q&A] doubledotdot@gmail.com:
I should be getting this unit in before the weekend. It will be going in a 2010 VW Touareg and as far as the research I've done so far i read that the CANBus adapters that are supplied are for CANBus V2.0 Only. The switch from CanBus V1.6<->V2.0 Happened sometime in 2007-2008. So if your VAG Vehicle is old enough that it uses the earlier CANBus version it will most likely have compatibility issues.

Welcome back ptclabs. You may want to consider building an Xposed module to override the existing connection management. It allows a much easier reflection interface imo. You also wouldn't have to deal with package signing. BTW, there would be no way to take the existing system package signature and apply them to another app due to the SHA hashes being different.

[MTCB Android Head Units Q&A] CARRisma:
So with all the recent talk regarding antenna boosters vs antenna power injectors and how some setups provide power to the antenna, this has made me wonder… From the back of my JY HU, along with all the other wires (ACC, PWR, GND, KEY1, speakers, etc), one of the unused wires is labelled something like ANT. I've always assumed it was there to provide a signal to extend telescopic aerials where fitted. As my car's aerial is integrated into the rear window, I assumed it wasn't needed. But, after all this recent talk, I'm wondering if this wire provides a power source to antennas that need power?
[MTCB Android Head Units Q&A] OBeerWANKenobi:
I'd put a meter on in and see if it keeps providing 12V as long as the radio is on. If so, I don't think there is any reason that it can't be used to power an antenna unless that antenna draws a lot of power, if so; see below. You could also use the remote wire or "amp" wire as they may be called. The only possible difference I can think of is that the "ANT" power may only be on when the tuner is on and the "AMP" or remote wire will start up as soon as the head unit is booted. If you hook any of these up to more than one peripheral though (or if the peripheral pulls a lot of current), I'd use the wire to flip a relay instead so you don't draw too much current through the wire. Multiple amplifier setups (and other peripheral car stereo goodies) use the remote wire hooked up to relays in this fashion.
