which MCU is it now 2.16 or 2.17 ?

You instaled the unit in the car and not flashed new firmware?
[MTCB Android Head Units Q&A] TooBusy:
Find it if you can

Great idea! Can you do that for me; I'll buy you a beer.

i need to clarify something missed, what i ment "installed" is i already installed it on my car, i got this unit from here http://www.aliexpress.com/item/Free-8GB-card-Pure-Android-4-4-OS-Speical-CAR-GPS-for-2DIN-universal-car-with/32260872574.html

and it is MTCB-JY-V2.16 (not 2.17, i misstype it before)

i'll try to ask the seller for the firmware
[MTCB Android Head Units Q&A] marco.lav:
Hello andrea

I do not think the update / downgrade the MCU has improved the AF.

I believe that the implementation has always existed, but it hurt.

thanks a bad signal will have a disastrous effect.

I think the car radio that are sold in the Italian machines, have a stadium to receive more "cured", so they can better receive the signal.

I say this because having rebuilt exactly the same condition amplification in my car, the UH current and original, receive and tune in a different way the same issuer.

I think that a bad configuration or careless stadium frequency is also the cause of the malfunction of AF.

I purchased another FM antenna with 20 dB of gain.

Come the install and will update.

(Chinese products suffer from a lightweight design, and often results in a quality not excellent)

Not entirely true.. He may be looking for a way, like me, to copy off the original MCU.

Mine is not available in the repository. KGL1-v2.03 (but ironically, it's a universal 2din unit, not a BMW one)

Mine has the home, back, eq/amp, GPS and eject buttons on right side along with a volume knob.

I would love to try a different MCU, but want to be able to restore the original if it all goes south.

Hello,

I thank you for your work.

during two tests I think I came across a Null Pointer Exception;)

if I try to delete the list of the logs when it is empty, the application fails :(

one thing not clear to me,

The server program, is the same that I install on UH?

I thank you in advance;)

You could try de-compiling the radio.apk and changing the mode it uses that way.

[MTCB Android Head Units Q&A] staneb:
My PIN for OBD is 1234, but I don't think this should matter.

Regarding the late start of processes that wait the BOOT_COMPLETED intent, I just installed a Malaysk ROM from 4PDA that has Next launcher instead of default one and all processes start normally without any issues, so I can confirm that it's a launcher issue. I remember someone replaced the default 4.4.4 launcher with the 4.2.2 one, wonder how that affected the loading of startup processes. Maybe someone could try the KGL 4.4.4 version...
[MTCB Android Head Units Q&A] marco.lav:
I never extract sources from an apk,

if anyone can 'do and pass me the source, I can lose a bit of time.

I am also certain that the apk in some way can better manage AF, overwriting the existing function, or creating a similar, but managed at the application level

I use Android Studio
[MTCB Android Head Units Q&A] typos1:
It should auto detect, if it doesnt, boot into recovery and scroll to "install update from SD card", then press ok.
[MTCB Android Head Units Q&A] agentdr8:
It's possible, but losing the presets doesn't happen on every boot (or shouldn't), only when certain things happen like hitting the reset button while the OS is running. For now, I think it would be pretty low on the to-do list, but I can add it.

I didn't think so either, but maybe it does? Those 2 other individuals seemed to have success after changing it to match their adapters.

I've been picking through the stock KLD launcher code to see if I can figure out why it's consuming/delaying the BOOT_COMPLETED intent, but I haven't found anything yet. I had an inkling that it was responsible for the problems, thanks for the confirmation.

So for those that aren't tied to the KLD/KGL widgets and want services/apps to start when they should at boot time, it makes sense to try an alternative launcher. I think I may just load up Nova and be done with it.
[MTCB Android Head Units Q&A] typos1:
Would be good if we could figure out how to implement the radio/music widget (at least like KLD do, with 1 changeable widget for both rather than KGL's separate music and radio widgets) as a general widget for use in any launcher.
[MTCB Android Head Units Q&A] ftsur:
So I'm still struggling with the the Rockbox'd ipod causing the head unit to crash when it's plugged into a USB port. It says "preparing storage" , but the unit becomes unresponsive and reboots to VW logo and won't get any further until I power off the car and back on again. I pulled my SD card out to see if that made any difference, it's the only thing I could think of besides the firmware being different. I really hate to have to go back to 4.2.2 just to test all of this. I'll loose all my settings, apps, etc. Any ideas??
[MTCB Android Head Units Q&A] staneb:
Maybe I wasn't clear enough, I did change the PIN on the HU to match the OBD pin, but had no success in pairing.

Hi,

Thansk for all the info on this topic very helpfull.

I have a Eonon GA5153, so a Klyde, with mcu 2.08 and 4.2.2 at start but I have directly update to mcu 2.20 and coudu 4.4.4. This unit is installed on a VW Passat SW 2009.

I have the good info for the opened doors and also all the steering wheel control, and sometimes the MFD which display Audio/SD/Video.

Everything seems ok, I'm just having some problems with Android.

I'm trying to use Here Maps on this unit which have a resolution of 800x480. I have Xposed installed and also AppSettings but I can't find the right combinaison to make it work. I have seen that someone is using it so can anybody share his configuration ?

Hi anybody has this app radio I like it better
[MTCB Android Head Units Q&A] typos1:
Thats the 4.2.2 radio app, there are 2 slightly modded versions on the first page.
[MTCB Android Head Units Q&A] agentdr8:
Haven't found a way to increase the profile support, sorry.

There's ways to get android to launch apps at bootup (install-recovery.sh or init.d), but there's no native way to send them to the background (or lower in the task stack), except if you bring another app to the foreground. What's the use-case? These headunits are pretty aggressive when it comes to memory clean-up, and apps that aren't focused (foreground) tend to get killed off within a few minutes.

[MTCB Android Head Units Q&A] theoreticaljerk:
Just loading up another launcher does not fix this. I run Nova and still have this problem. Would likely need to weed out and freeze the stock launcher if that wouldn't break other things.

---------- Post added at 04:55 PM ---------- Previous post was at 04:52 PM ----------

So, I cleared all settings for XposedMTC then set everything back up using the steps another user recommended and everything is working fine.

I should have tried each fix separately but I didn't think about it until after I had done it already.

(this is about the dimmer mode always dimming no matter the time of day)
[MTCB Android Head Units Q&A] agentdr8:
I see. You could most likely do this using [MENTION=6041319]dsa8310[/MENTION]'s method linked in this post.

Yes, the stock launcher has the RECEIVE_BOOT_COMPLETED permission (and associated receiver), so unless it's frozen/removed, it would still cause problems. I don't believe there are any side-effects of removing it from /system/priv-app, but you may want to back it up just in case.

After thinking about why this happens, I've realized I put in a logic flaw that can never be resolved by the SunriseService, so that's why manually setting the times first and then changing them works. I can resolve this for future releases.

flat sound on rca outputs

Hi everybody

i have a klyde unit running 4.4.4 and 2.20 mcu. I am having issues with sound quality. The sound from the rca output is horrible, lacking in low and high end of sound.

Does anyone know if the speaker outputs can produce a cleaner signal, when used with a high/low converter?

Thanks dude! I'll give it a shot. It would be nice if it resumed when it was running when unit was powered off and not auto start if it wasn't. With it auto starting now, sometimes both the radio and power amp come on at the same time if the radio was the last thing I was listening to. But if power amp was the last thing I was listening to, I'd want it to resume.
[MTCB Android Head Units Q&A] typos1:
What car are you using it on ?

I had a similar problem on my car (with OEM external amp), other people have reported the same problem on the same car using the same cable, so I thought the problem was with the car and its amp set up (Bose). I got a hi-lo converter and the sound is great. The OEM headunit has a built in hi-lo converter, so I reckon that as the OEM amp set up is designed to work with a hi-lo converter and thats why iy sounds better.

You may well find a hi-lo converter specifically for your car so you dont need to cut the wiring harness.

Hello,

I read your post,

to modify the radio interface, have you MCRadio sources ?

we would need to override the function FA, or to create another one that works with a different criterion. "AF Evoluted" in Button "AFev ;)

mutually coupled with AF.

just for example in

// java Pseudocode
Station sintonizedRadioStation;
int minSignalInDb = 10; // value for exampe
// called from system when the signal is low
while ( (sintonizerRadioStation.getSignal() < minSignal) ){
Station newStation = System.findOtherStation();
if ( newStation.getName() == sintonizetStation.getName() ) {
// found the some station
SintonizedRadioStation = newStation();
}
}

is not efficient, but it is what it takes to us in Italy.

if you can help,

There is an alternative scenary, which is a bit more complex to explain.

can you help me in any way?

or give me the source code, or I implements the new feature?

I thank you in advance.

- The sound is good.

- Responds quickly. (With Android 4.4.4 Light)

- Built-in microphone does not have a good feeling.

- The Navigator responds well.

- The BT is multichannel obd

but perhaps it is a very problmema heard in Italy

On my UH,

I have the impression that there is only one color, Blue

so it works only in shades of blue, and is connected to the Red :) ehehhee

I think we used a diode Blue, and not a diode RGB.

I think that by opening and inserting a diode rgb, it solves the problem.

- Work to Do

** Place the antenna Wireless

** Pull the microphone, or replace it with a more sensitive.

** Boost better or verify the stadium AM / FM, has little sensitivity.

Screen stucks black after shifting in reverse gear

Hi folks,

succesfully updated my KGL (Mercedes W209 shape) to 4.4.4 (the modded one).

Everything is fine, also Torque and Dash Commander is connected again via bluetooth dongle!!!

A new issue is the switching to black screen, when shifting in reverse gear (no rear camera installed). Usually the normal screen should come back when shifting back, but since I updated, the black screen stays and I have to reset the HU, which really is anoying.

Any ideas, what to change?

I thank you for giving me the post.

I seem to have understood that the malfunctioning microphone for hands-free is caused by the capacitor C102, which connects the microphone to the BT device (I tried to make a voice recording and audio I looked good).

is correct what I understand?

// My UH does not have a External MIc ....

If I understand correctly, you can post a picture of the area where you have to remove the capacitor?

in this way we can also have feedback on the various devices.

// Have you seen how it is configured stadium AM / FM? I think that this also needs attention :)

This confirms a lack of attention to the electronic design.
