is there anyway you can make a quick drawing/schematic on how you setup you mic system?

Thanks in advance
[MTCB Android Head Units Q&A] typos1:
Yes, but as some people say the radio sounds awful and as most people say that Poweramp sounds great, seeing as they both go through the internal amp (unless youre using the RCAs) we must therefore conclude that its the radio at fault rather than the amp, because as we've said, poweramp sounds good and its going through the amp, so it cant be the amp.

Its been suggested a fair few times in this thread and in the AN-21U thread, also in the "device request thread", but the powers that be dont appear to agree that Android headunits should have their own section..

I am the same way. He did an excellent explanation but I'm such an electronics newb that a better pic or diagram would be huge. With that being said I'm just appreciative for the efforts so far. There is a light at the end of the tunnel that isn't on the front of the locomotive.....lol.

[MTCB Android Head Units Q&A] agentdr8:
There was a modified MTCBackView.apk posted earlier in the thread that someone had modified to remove those 4 buttons along the bottom for 4.4.2. I think the stock 4.4.4 BackView no longer shows those buttons if you don't enable the radar option in Settings->Driving Safety (or something like that).

Hi have a JY unit too, and have tried to add an external microphone.

I can't find a C32, so rightly or wrongly I cut the mic leg on the BT module to disconnect it from the main board and soldered the external microphone socket direct to the BT module.

The internal microphone still remains working for android apps without me having to perform any other mods. The strange thing is the audio quality seems much, much better. The buzz in particular that was there earlier is now almost gone completely.

The bad thing is that the external microphone does not seem to operate at all.

[MTCB Android Head Units Q&A] theoreticaljerk:
Yeah, I saw that. Gonna try it today when I get in the car. Probably just a stupid oversight by me. lol

Been real happy with the stability of 4.4.2 so far. Only gripes are the following:

1. When the system boots, it takes 5 seconds or so to become responsive once showing the home screen. Well known issues, knew what I was getting into there.

2. I'm using Google Now Launcher which works great with one weird thing. Once the system does become responsive, a few seconds later, it jumps from my home screen to the Google Now screen. This happens every time. A little annoying but nothing a quick swipe to the left doesn't fix. This happened when I was on 4.4.4 also.

I'm also only KLD MCU 2.16. Only gripe there is that the backlights for the buttons are on all the time. Otherwise I haven't noticed any issues.

Help for upgrading

Hello!

I have toyota universal Erisin unit with 4.2.2 firmware with no canbus.

I'm very happy with it and dont want to brick it, it has no micro usb connector on front (just plastic "protector)" there might be actual socket under but i have had no time to check that.

But i have some problems with wlan stability (drops all the time I must do something to it)

My device has following properties (attached), i have also stored the factory menu settings in case they are needed.

-MTCB-KGL-v2.01

-Model S07

If i have understood right, the right procedure is to download this image:

http://huifei.fs-fileserver.de/content/firmware/coudu's_roms/4.4.4/800x480/

(KLD_4.4.4_800x480_141208_rooted_light_reparted_init.d_v4.1.zip)

& correct MCU file should be:

https://drive.google.com/folderview...haring&tid=0BxmzvLRI7-eNeVA2SWkwM1pLZ28#listv

KGL v2.09 version?

Just put these on sd card and to gps hole and system should ask update?

I readed regarding the recovery procedure., should i install twrp or what else i should do to be able to recover from brick?

I have understood that the risk is not very big (but ofcourse still existing).

Best, Jukka
[MTCB Android Head Units Q&A] jugi:
better, but not perfect

Hello!

Thanks!

Its much better now but as at least in europe many stations DO have RDS name, its more important than Mhz reading.

I would say that the text could bee little bigger and lower but maintaining approperiate gap to the upper tittle (now the space between the RDS name and tittle is too small)

Have you tried dissabling WIFI optimization in the settings?
[MTCB Android Head Units Q&A] agentdr8:
Correct. You can't use TWRP to flash the update.img or mcu.img, but it can be used for some advanced recovery after you've applied the system update. Look back a few pages for [MENTION=853627]coudu[/MENTION]'s post regarding TWRP.

After installing system updates, I always flash TWRP (using flash_image) so that I can get out of bootloops if need be (usually caused by my testing new things in XposedMTC).

I don't know if that particular module is compiled into the kernel. We have no kernel source, so no way of working it into one if it isn't dynamically loaded.

Seems to be resolved in 4.4+ firmwares.

Flashing OS firmwares (update.img) don't seem to be risky, it's the MCU updating that can cause bricks. As long as you don't flash an incorrect MCU image from a different mfg, it should be fine.

Hi pakidermo5000,

can you help me with the best way to go on installing the update.img

Ive got the nandroid backup, but my bootloader is still useless as i have no front USB( or the info on how to)

So i know i am taking a risk here.

What tools to you use to apply the MCU and system update img files?

Just recovery mode? and flash from SD, a small tut would be nice.

I dont need TWRP for this right as this will break also if something goes wrong.

My model came in on the 22nd of may, and its bootime is about 40 seconds.
[MTCB Android Head Units Q&A] 1-2-Hak:
The easiest way is to put the update.img and mcu.img onto the root of an sd card and place it into the gps sd slot while the unit is on.

This is a std factory upgrade - it will detect the update files prompt you to do to do the install.

No special modes required for this.

Thank you for the infos and pics,can't wait to get mine :D I hope the VW integration is not bad,obviously I don't expect the perfection like it would be with the original RNS,but if there is a way to get the turn by turn indications on the CBD would be awesome.
[MTCB Android Head Units Q&A] pakidermo5000:
Yes, as 1-2-Hak said just put the files in your gps or mp3 sdcard, then use either wifi ADB or any file manager to copy the files from external_sd to /sdcard

once you reboot the unit (normally, no need for recovery or anything) you will see a pop up asking for update, say yes, and wait, and pray for nothing bad to happen... :) (the unit will automatically reboot into recovery and update from there, all automatic). Once done,

you wil have to root again after the update. The same rooting tool works for the new update.

then, remove the images from /sdcard or it will be popping up everytime you boot.

The whole thing about TWRP, bootloader mode is just in case things go bad...
[MTCB Android Head Units Q&A] pakidermo5000:

The AN21-U uses the MSTAR 1.2 Ghz dual core chip (thread here: http://xdaforums.com/showthread.php?t=2528349 ).

The one with the Telechips processor is the WD8801 (thread here: http://xdaforums.com/showthread.php?t=2618348 ).

It started out with a 1.7 Ghz quad core Samsung Exynos chip (very powerful but prone to overheating) with 2Gb of RAM and looked very promising. Some Russian members of XDA bought them, there were a few teething probs, Drakey83 (from US) bought one anyway, when it came he discovered that it had been downgraded to a Telechips dual core 1 Ghz, he wasnt happy, obviously :-/

I dont think its a scam, just stupidity/incompetence - they obviously had problems with the Exynos (as have a lot of people, including myself) so they replaced it with a Telechips, failing to change the processor speed in the advert and failing to let people who had already ordered it thinking it was 1.7 Ghz quad core, know.
