I opened the front panel and had a look inside. I found the location of the mic (Click images for larger size)

Where is the location to disconnect this mic from the external mic?

Edit: Just did some more searching and reading. Since I have a Klyde unit I have to cut c32. Do I also need to add a new external mic input or can I use the existing one that I have in the unit?
[MTCB Android Head Units Q&A] coudu:
OK, it should be good now, I re-uped them all from fiber access at work :p
[MTCB Android Head Units Q&A] n3m35155:
The C32 capacitor you need to look for should be on the mainboard over near the Bluetooth board (It's the board on the left side of this pic that is vertical).

The Mic+ and SGND connections you want for the new external mic are marked on the left side of that Bluetooth board also.

I found it easier to take off (in order) the top cover, dvd drive, LCD panel (front) and side cover the BT board is near to get clear access to the outside of the Bluetooth board.

NOTE: I did not disconnect any of the ribbon cables..

7" screens are available with both resolutions, if you arent sure what resolution your unit is, then check the build prop or download a resolution changer app form the Playstore that will tell you. If you put a 1024x600 resolution image on your unit the left and bottom of the screen will be cut off, making it difficult to use, but with patience it is possible to use it and get into recovery and flash the correct resolution.

1) Rootable?

2) He spoke of and issue with apps ( i heart, pandora, etc) needing to be played on a non broadcasting station and resulting in background noise. Is there a workaround for this?

3) OBD2 capable? I don't know which BT chip it has (5 or 6)

4) Upgradeable to Android 4.4? either .2 or .4?

Umm I think thats the main ones for now. Im 100% sure there will be more..

[MTCB Android Head Units Q&A] RyanBRZ:
Sounds like it's in the same family of HU's. When you get it, go to about section in settings and post the MCU value. That will tell you who the manufacturer is and if you can use the hacks/firmwares/mcus/etc that are listed in this thread. See post above by RekoOo-77 .. that middle "KLD" value tells you its a Klyde unit.

Unit draining car battery

Hi, has anyone had issues with the unit draining the car battery. I've had my unit for 4 months now and had to replace a OEM battery that was just over a year old... The unit doesn't shut down when long pressing the power button, it basically just switches off the screen whilst still running everything in the background.

Please can someone shed some light on a salutation for this. Maybe getting the unit to power off once the key is removed from the ignition or something in that line.

Any help will be greatly appreciated.

I just have a question : Is this possible to reaffect another software to the physical DVD button ? I mean, I would like to start the MTCAVin.apk software when I click on the DVD button on the right instead of the DVD program that I never use ?

Thank you in advance for the answer.

Thanks for the reply [MENTION=6041319]dsa8310[/MENTION]. I have a VW Jetta 5 and the unit fits plug and play to the car's harness. My OEM HU works perfectly so how can i go about fault finding the issues regarding the CAN Bus or the red "remote" wire? Visually everything seems to be in order.

The element lighting goes on and off with the ignition, but the Power on or shutdown is not influenced by removing the key. I have to power on and power off manually. When long pressing the power button it shows shutting down, but it only goes into screen standby mode.
[MTCB Android Head Units Q&A] coudu:
On vw cars with canbus there is no 12v ignition on harness both the red and yellow wires are permanent 12v so you need to disconnect the red wire to let the canbus box control on/off. you can also disconnect orange wire so the canbus box controls illumination.

JY

Apologies if this is already mentioned somewhere in these 400 pages :) but I have recently purchased (and rooted) one of these units:

From that I gather it's a JY unit with MCU version 2.08. Just cut out of the pic is the Android version which is 4.2.2

I'd like to update to 4.4.4. Is this recommended? Do I need to upgrade my MCU version as well?

According to the first post, the latest MCU image for JY is 2.11. Is that correct?

Also according to the first post, any Android version can be used however there seems to be an exception for JY (see bolded):

"3- Download any Android part you like (update.img), KGL/KLD/GS/RM/JY they are interchangeable (see Custom Firmwares section below). Latest version is Coudu's 4.4.4 v4.2 (based on KLD), see here , or see Malaysk's roms w/ and w/o NEXT launcher, also 4.4.4 here, latest JY version is this one"

So what is that about? JY has to be a specific one?

For MCU versions, is there a changelog somewhere?

Thanks in advance for any help you can give me. Loving this stereo already. :)

[MTCB Android Head Units Q&A] Hein3G:
Thanks for all the feedback, i'll have a look at the unit and try the "disconnect wire" approach.

A question regarding the reverse camera, i do not have one connected and when the car is put in reverse it shows "no signal". Can i cut the reverse wire (i think its a pink wire) to stop the reverse signal being fed to the HU?

Then also, i have asked this before but was unable to find a salutation. When using my SWC the volume +/-, it skips 2 increments at a time and when pressing skip FWD or BACK it skips 3 songs at a time. A have tried the app's that was recommended to solve this issue, but no luck. Has anyone had similar issues with the VW SWC?

The unit is still new and i have not updated the firmware or MCU so it is still stock standard with JB 4.2.2_28092014 and MCU: MTCB-KGL4-V2.01 Aug 18 2014

KGL offical update

Hi,

I follow this huge topic from 1-2 weeks because I bought a KGL-6003 from aliexpress.

I have some issue with it (Wi-Fi and GPS don't work :/). The seller send me an official update to try to solve these problems.

I think maybe this update can be useful for community, so I share the link to download it. I will test it this evening.

Android version is KitKat 4.4.x This update is for 1200x600 px screen resolution

File name : KGL_rk3066_4.4_h(20150115).zip

Now a lot of work. I think that will soon lay firmware for 1024X600 dated January 13 KLD ;)
[MTCB Android Head Units Q&A] Ken Ishiimoto:
Good Morning,

(please excuse my english)

when i buyed my JY HU it started with the same specs. The sound and the receive of the Radio was not was i expected. Then i installed root master v2.11 and updatet Android to Coudus KGLv4.4.4v2 800x480. (You can update to any Android you want like KGL, KLD, JY etc, just look for the right resolution). The design between JY original Android v4.2.2 and Coudus KGL v4.4.4 or KLD v4.4.4 versions are very different, you have to test it for yourself which design you prefer, it only takes a few minutes to change the versions . "ES Datei Explorer" from playstore, is a helpful thing to copy prefered apks from one Android Version to another, so you can build your own look of the system. Both Roms from Coudu runs very well on the JY, no probs with Bluetooth, Wifi or connect the Smartphone. The receive of the radio improves too. The Design of KGL was a little bit boring to me and so i changed to KLD:

Start Screen from KGL: bilder-upload.eu/show.php?file=7b77cf-1422427665.jpg

Start Sceen from KLD: bilder-upload.eu/show.php?file=6dce50-1422427729.jpg

Media Player from KLD: bilder-upload.eu/show.php?file=ccf6d7-1422427752.jpg

I had the feel KGL reacts a little bit faster than KLD when you slide the screens, but iam not shure.

With the mcu v2.08 everything works fine but the sound was still like "in an Barrel". So i updatet the mcu to v2.11 and it improves a lot. But when i now hit the button "Speed increase" it seems to be it clears my cache from the HU(?)

So i updatet once again to mcu v2.16 (the file i extractet from the link in the post #7500) The Sound improves once again but the error(?) with the "Speed increase" button stays. No matter to me, i dont use it anyway. The only thing i cant really use, is the Dimm-Wheel of my Ford, when i dimm the Dashboard of the car, the HU begin to flicker. Like a conflict between them. So i avoid to use the wheel.

IGO and Navigon runs both without any change in the system , but TomTom did not. I installed SDFix:KitKat from the playstore. The apk check is there enough space intern or on the SD-Cards and ask where to install TT. It works on my System with a 32gb Card in the second slot.

So, i hope I could help a little.

Greetings Ken

Thank you for the suggestion. I tried that a few times. Mine is in my Wifes 07 Chrysler 300. I actually took it to another Installation company thinking the first company screwed up the wires or something. So they took about two hrs troubleshooting it and finally cut the wires and ran the stereo to separate speakers in the store and it did the same thing. So I'm waiting to hear back from the AliExpress seller. My line of questioning toward the seller is getting lost in translation as they are started to get pissed with me asking about how to return for an exchange. Anyway, they asked me to make a video and send to them to see if they could figure out a solution. Here it is for comparison. http://www.mediafire.com/watch/c6bd29jgyk54o88/CAM00244.mp4

I'm on Klyde 2.21 with last Coudu rom.My car is a VW Pasat.

Seems that the new music player widget has the cover art so maybe it's just time before we have the full cover art and also the shuffle, it will be awesome, because this app stays simple.

My central display (between speedometer and rpm) also displays the track number and elapsed time, I think it's more on the MCU part.

Peculiar frequency-dependent audio distortion

Apologies if this has been mentioned before, I have read most of the thread but am only up to page 500-ish. I also did search but found nothing like this.

Whilst testing some speakers, I ran a frequency sweep on the headunit (I have a Joyous as noted in my sig). When the sweep gets to around 450Hz, up until 600Hz, the main tone is copied with one that appears to be 3x the frequency. This does not depend on volume but purely on frequency and can be heard as a change in tone to one that is much sharper. I have tested with equaliser flat and loudness off. Please see the attached screengrab (taken with my mobile phone).

Can anyone else test out this behaviour?

I used FuncGen Signal Generator on the headunit and Spectrum Analyzer on the phone.

The KGL widgets are different from the JY and KLD widgets. KLD and JY have a widget that is built into the launcher and displays either music, radio or BT music, depending on what is playing, but KGL have a separate widget for radio, music and BT music and theyve been the same since 4.2. As the KLD and JY types are built into the launchers, you wont be able to see them listed as widgets. You are right though, the KGL ones can be put on any of the other types whether 4.2, 4.4 or 4.4.2, personally I dont like the look of them and I dont like having 3 , I prefer having one multifunction one like KLD/JY. What I d like to do at some point is to try and make a multifunction one that is a proper widget (ie shows up in wuidgets as a widget) and not built into the launcher.
