I haven't modified any roms, just uploaded them to the repository. Most likely you're referring to [MENTION=853627]coudu[/MENTION]'s rom.

You create a script (text file) in /system/etc/init.d/ named something like 99foldermounts, make sure you chmod 755, chown root.root

In the file, you would put your mount command. What directory(ies) are you trying to mount?

Check the dimmer value. If it's 0, it can make your screen completely black during dimming periods. Not all units can do this though (my GS can't get any darker than 10). I should probably change the default to something higher than 0.

Hmm, I haven't looked into how the DVD app displays video, but I'll see what I can find.

[MENTION=853627]coudu[/MENTION], Thank you so much for providing the images and the clear instructions. I was able to successfully flash the image on my JY (Eonon G2110) unit and later restore data using TWRP. The only issue I'm having is that Torque crashes on start. I tried clearing the data, cache and even reinstallig it to no avail. Can you please let me know what else can I try? I have a BT OBDII device so I'm eager to test it.

Note to JY owners: For some reasons, the terminal emulater doesn't recognize the last two rows of the on-screen k/b. I tried everything from changing the resolution to changing the keyboard layout but it didn't work. Ultimately, I had to connect a physical k/b to complete the install process. So before you attempt to update just keep this mind and have a usb k/b handy.

Maybe install one of the logcat apps and see what errors get thrown when your apps crash. That might be able to point at the specific cause.

Amplifier dying ?

Hello all,

Just to let everybody know ( I guess) the power-amplifier of My KGL-7620G universal unit is dying. It might be a coincidence, but it also might tell something about the global quality of these units. Time will tell ...

I bought the unit on may 26 of this year 2014 and the unit always worked more or less as it is meant to be. Last sunday me and my wife were driving to a garage sale and suddenly the sound almost vanished. I first thought it was bad radio-reception beacause we were close to the border line of Belguim and The Netherlands, but navigation and Poweramp also gave weak sound. I still can hear sound if I put the volume way up, but its with a lot of hiss and crackling (and very bad). If the volume is up while booting the unit, I get a few blobs through the speakers, so bad thing ... If the sound is muted I also get those blobs while booting and sometimes even a sharp high sound that slowly faints.

I don't know how the amplifier looks like because it's a pita to get the unit out of the car and I didn't open the unit when I bought it because all worked well out of the box.

Are there some electronics wizards among us (stupid question I know) who know if this is a leaking capacitor or something trivial? I have not the intention to send the unit back ...

Ronny.

Sound quality

I have KLD with 2.02 MCU. The sound quality is far not perfect. The high tones are OK, but the low tones are crap. My factory radio was a basic one, but with the macAUDIO CFX 2.16 component set sounds very good. After I changed the head unit for the Klyde KD-7003 the sound is "empty". Sorry I don't know how I can tell you. I tried EQ settings and LOUD option, but I can't hear real low tones. I tried the same CD-s and mp3s (320kbps) as in the factory head unit. There is no noise or anything else, the sound is clear, just can't hear any real bass. I read here lot of you said the sound qualitiy is decent and better than a basic factory head unit, or at least the same.

So my question is, what is the main reason for the sound quality? The MCU or the Android system? Has anybody same problems?
[MTCB Android Head Units Q&A] Gus84:
What back button? I haven't got any physical back button on the unit.

If you mean the up and right arrow on the screen, off course it work.
[MTCB Android Head Units Q&A] gy_ro:
@ peti007 : Lack of a good equalizer. I think by installing PowerAmp for example it is possible to 'tune' your highs and lows. Exit from Poweramp and start the other app. It will sound much better.

[MTCB Android Head Units Q&A] mrbubba999:
Still got really bad FM reception on my unit. As it's a Skoda, the standard unit had a built in FM amplifier, I've plugged the provided amplifying cable in, but it doesn't improve it a lot (if it's unplugged then I get hardly any reception)

Any other suggestions?
[MTCB Android Head Units Q&A] ultradj83:
Yes, I restored with TiBu, but next, seeing the problem, I uninstalled any affected app deleting all the files and reinstalled, nothing changed.

On today, I installed a pair of new apps I never installed before from Play and they're affected by the same problem.

That's why I think a factory reset will not solve this problem... [emoji27]
[MTCB Android Head Units Q&A] samsingla:

I made a TWRP backup and retried coudu's v4 4.4.4 KitKat firmware. I tried doing a Factory Reset, as well as changing the default installation media. Everything seemed fine until I rebooted and Spotify and ES File Explorer started having problems again. I found that if I ejected the SD card from the MicroSD labeled slot, ES File Explorer would open. However, Spotify seemed to be a lost cause. I ended up reinstalling v3 4.4.2 KitKat and restoring my backup. Oh well, I tried.
[MTCB Android Head Units Q&A] ultradj83:
Well on my system there're more affected apps.

About Spotify I'm dealing with them: https://community.spotify.com/t5/Help-Android/Crash-on-Android-4-4-4/m-p/997017 .

There are many people on 4.4.4 having troubles, maybe we just need Spotify to update the app...

Pandora not loading

I am running the 4.4.4 on my Radio and it was working great. Pandora all the sudden stopped working. Crashes at boot up all the time. has anyone else seen this? Thinking about going back to 4.4.2 till a stable 4.4.4 is out.
[MTCB Android Head Units Q&A] mrbubba999:
Is that one working OK for you? My unit already came with something like that, but it is very poor.

I've found one similar to the one you linked, but it's in the UK

http://www.amazon.co.uk/Autoleads-PC5-149-Aerial-Adaptor-Single/dp/B004TW7UV2

Doing some research on one of the VAG forums, it's the diversity aspect of the systems and none of these adaptors are actually able to use the system.

I was also looking at a replacement aerial, but can't find one with any decent reviews
[MTCB Android Head Units Q&A] c0py:
Is there an official KLD 4.4.4 for 800x480 out?

I have tried the rooted one by coudu but too many apps crash including google play services & launcher. I have reset & erased NAND flash as advised but this does not seem to resolve it.
[MTCB Android Head Units Q&A] samsingla:
I am not sure. I am able to connect to the adapter just fine with my Nexus 4. I have attached a screenshot. So I'm thinking it's something to do with the head unit.

I am using coudu's 4.4.4 image. I understand that it doesn't work with 4.4.2 but even in the later version I see the exact same issue. It shows connected to the adapter but not MCU. I have three LED's on the adapter, Power, OBD, and PC. When I pair the device to either the phone or head unit only the Power led is lit. The moment I open up Torque on phone and go to Adapter Status, the OBD led starts blinking and in a few seconds it shows OK for 'Connection to ECU'. However, when I try the same from head unit after pairing the adapter, the ODB led never blinks. So I assuming that Torque is not able to communicate with the device. I saw the exact same thing with 4.4.2 (showed connected to adapter but not ECU).

I also saw something strange with Google Maps. It is defaulting to Night mode in navigation mode. However if I have it running without any route/directions it works as expected with white background. Any clue?

[MTCB Android Head Units Q&A] theoreticaljerk:
Ok, so, in the 500+ pages I'm guessing someone ran into this....but I'll be damned if I can find it.

Pretty simple, I have the Pumpkin unit that came with 4.2.2 and I've upgraded the MCU to 2.12 and Android to 4.4.4, the XDA version that comes rooted.

Anyway, on both 4.2.2 and 4.4.4 when I go into the Factory Settings using the password 126, I can see everything and select stuff, but when I hit Apply, the unit beeps two times and the changed settings do not take. For example, if I change the boot logo, hit Apply, it beeps twice. When the unit restarts, it's still on the default boot logo.

Any ideas?

Does anyone know the voltage output of the backup camera line on klyde units? Trying to plan ahead for my install, I wont have the unit to check for myself for another two weeks.
[MTCB Android Head Units Q&A] agentdr8:
The headunit doesn't provide 12V on that line, only detects when that line is raised to 12V. Your vehicle usually has a wire that goes to +12V when in reverse. That's the wire you tap into. Or it might be provided via CANBUS, if your vehicle is so equipped.

EDIT: I forgot you have a BRZ also. There's actually a reverse wire in the stock radio wiring harness, that could be used with the Fujitsu Ten headunit. I can't recall which wire it is at the moment, but that's the one I used for my GS install. For the camera, I powered it via the reverse lights wire that's beneath the trim piece near the trunk latch (have to remove the plastic and probe the wires to figure out which one goes +12V when in reverse).

For those that are wanting to use Nova Launcher in tablet/landscape mode, you can force it using Xposed App Settings. Set Screen (dp) to 800x1280 and DPI to 180 this will fool Nova into running in tablet mode.

Yeah, I ve seen that one, there is a thread on it somewhere, not sure why you cant get the 2Gb RAM version in Android only guise though, they only do it on the dual boot Win CE/Android version for some reason.

The RK3188 is a logical upgrade to the RK3066 the units in this thread use (RK3066 is 3 years old !), I m kinda expecting KGL, KLD, RM etc to swap out the RK3066 at some point, for the RK3188 and still use the same MCU.

My point was that for some reason you cant get a 2Gb RAM Android only version, which seems silly as the RK3188 can take 2Gb of RAM , I ve got an RK3188 Android TV box with 2Gb RAM, dont know why they even bother with a 1Gb version TBH. Agree about the Win CE thing, why would anyone want both ?

Great to see someone frome the manufacturer here!!

I can honestly tell you that if you could facilitate an open development for your units it would quickly become the most popular, I know I would replace my AN21-U with this in a heart beat. This community is eager to help troubleshooting and developing but too often slowed down by closed development. What would really help is the following:

- Method for obtaining root

- Kernel sources

- any other source code you can provide (whole rom would be great, native apps such as radio, etc)

- MCU communication protocol specs

- Bootloader and recovery specs - if custom recovery such as CWM recovery could be created/installed that would be great!

Giving at least some of these to the community and making this unit more "open" to development would do amazing things for your sales. I understand fears of competition copying your tech, but I can guarantee you that the advantage point stands in the hardware construction and price point. You guys have that down and releasing protocols and sources wouldn't enable anyone to match what you do best.

Welcome here, we look forward to a great relationship!

new here :)

I thought I had my mind made up on the AN-21, but now I run into this :) I have read the entire AN-21 thread and liked what I saw. But when I see this deck, now I am unsure what I want to go for. This new one seems really, really nice. I would like to know if the SWC will work on other apps like you can on the AN-21. That would kind of be a deal breaker for me. I also just bought a USB OBD II adapter to prepare for a new deck. I am curious to see if this works with torque as well. This however isn't a priority of mine. I would much rather know of the SWC will work. I currently have and OUKU (2.3) unit with a resistive screen. I am looking to replace this... and spring is coming up very fast and it is almost time to order the new one (my car is in storage right now). But now I am indecisive on what to get. I would like to thank the early adopters of this unit though. Your information really helps everyone out more than you know. I might have to wait a bit until more information comes out to pull the trigger :)... but this one at the moment seems promising.

I actually wont be there to sign for it. Its going to my parent's house, because in my community, kids love to steal boxes off porches, when no one is home. Even though a couple of them have been caught and had charges pressed, it still happens. Crazy thing is, that is the only real trouble we have. There havent been any reports of cars or homes broken into, think its because everyone has alarms, etc.

Anyways, I have 100% buyer protection on the product from AMX, so really not worried about it. :)

feature demands

Hello to all!

I'm still looking for an android-device that supports kind of "Speed dependent volume compensation" as this feature already exits on (in-dash) other units, but Keylo told me that the KGL7683 so far doesn't support this feature.

1) Do you think it might be an option or possible to be implemented with a rooted device?

As far as Keylo told me this unit has one-way CANBUS, meaning that SWC works, but can not Display Information on the MFD.

2) Do you think a two-way CANBUS is realizable?

I'm still hesitating to buy this unit for my Audi A3 (8P)....:eek:
