[MTCB Android Head Units Q&A] parazit26:
you have a 3,5mm jack coming from your can bus adapter. this jack transfers the can bus signal, so it means you have to connect key 1 key 2 and ground on this jack in order to get swc controls.

do you want to keep blue and me or do you want to make phone calls using your headunit?
[MTCB Android Head Units Q&A] liquidini:
Blue and me is junk :)

So i would prefer to keep the headunit calling.

Is it possible to see things like parking sensor on the android headunit?

thanks
[MTCB Android Head Units Q&A] parazit26:
[/COLOR]

yes blue & me is junk :) it was a lot of work to get all buttons to work with the headunit. for this i had to build my own can bus adapter and sniff the can bus codes :)

maybe there is a way to see parking sensors but it will be a lot of work to do this.

Klyde 4.2.2 MCU v1.98, Button Map + Upgrade

Hi,

I just got this unit for my Outlander and got to say im impressed.

A few questions and I have googled them and started reding the 500+ pages here but cant seem to find them.

1) I want to change the GPS programe How do I map the hardware button to the new gps programe? (And the other buttons to)

2) How do I improve radio recepton it is very weak should I fit a external amplifier?

3) Is it worth upgrading the MCU to 2.20 as cant find any info what each of the updates actually fix?

4) Is it worth putting 4.4.4 on and what will I gain by it?

Sorry for all the questions.

Thank You

Terry

GO TO SETTINGS GPS ALL THE WAY DOWN THERE IS AN OPTION TO CHANGE TO THE DESIRE APP.

2) How do I improve radio recepton it is very weak should I fit a external amplifier?

ON MY UNIT BY UPDATING THE MCU SHOULD HELP BUT ON AMPLIFIER SETTINGS LET IT IN FLAT IT WILL ELIMINATE A LOT OF NOISE.

3) Is it worth upgrading the MCU to 2.20 as cant find any info what each of the updates actually fix?

YES ( http://xdaforums.com/wiki/Generic_Android_Head_Unit/MCU_Explained ) ------ ( http://huifei.fs-fileserver.de/content/firmware/ )---------

YES THERE IS SOME GREAT FEATURES AND SPEED IMPROVEMENTS ESPECIAL IF YOU INSTALL A PRE-ROOTED ROOM

[MTCB Android Head Units Q&A] comptechltd:
Well, I will give you my uneducated opinions:

1) Under settings there is a way to select your GPS program. I'm not in front of my unit right now and it's very cold outside so I don't remember exactly where it is.

2) Check your antenna connection and make sure it is snug. You might read this: http://www.news.autopumpkin.com/car-stereo-radio-station-signal-is-bad-it-affect-the-radio-sound-quality/

3) I have yet to upgrade to 2.20 but I am going to. Many have posted that the sound quality increases significantly. It might help with #2 above also.

4) Up to you. KitKat has a number of enhancements but also has its share of problems. I am using [MENTION=853627]coudu[/MENTION]'s 4.4.4 rooted and love it so far.

Thank you for your two answers much apreciated.

You can just update the MCU cant you you dont have to do the os as well?

I also read alot of people dont like the radio app anyway is the only way to remap that hardware button is by altering code somewhere?

I would also like to change the launche at some time as it looks a little rubbish. Any suggestion?

Thanks

I like it better myself. You must rename it Launcher2mtc3.apk and copy it to system/priv-app and then change the permissions to 644. If you don't rename it to what is currently there it will cause problems for you. Copy the original Launcher2mts3.apk to somewhere safe.

Power button not working

So it seems that the power button on my unit is not working. I can push it but it does not do anything in android or in recovery. I am trying to do an MCU update but without the power button I cant select the option when in recovery (got into recovery by using titanium to reboot). Does anyone know how i can flash the mcu without a functioning power button? My unit does not prompt me to update when the mcu.img is on the gps card, it does for update.img but not mcu.img. I am running coudu's rom 4.4.4, JY MCU 2.08.

Modded Apps

Install app without adb when regular install does not work

Sometimes the app won't install normally and you need to sideload it.. This means that you need a computer and adb wifi. There is another way with which you won't need a computer. You just need to install a terminal emulator (you need root ).

1- Download the terminal emulator app you prefer

2- Download the app you want to install to /mnt/sdcard

3- Open terminal emulator

4- On the terminal navigate to /mnt/sdcard by typing

Code:

- cd /mnt/sdcard

- su

- pm install "NameOfTheApp".apk

Done, you are app is now installed.

You can do just the MCU, I would try the latest version for your machine and only go back to earlier versions if you have any problems.

Upgrade to 4.4.4 - there are about 3 launchers these units have with 4.4.2/4.4.4 depending on manufacturer (theyre all compatible with these units regardless of manufacturer) or put whatever launcher you want on it from the Playstore that you takes your fancy.

If you dont like the look of the radio app you can alter it using an xml editor or there are a few altered versions doing the rounds on here.

I don't have that radio/unit but I bought from that seller and everything went great!! Would definitely recommend them.

Had the radio in 2 days from shipping notice.

The version I have is this one..

http://www.aliexpress.com/item/2014...-1-6-GHZ-Two-Double-Din-6-95/32258654818.html

Basically the same unit, just without the motorized front panel. I figured the non-motorized is one less part to fail and doesn't stick out so far from the dash.

I would confirm with seller that it is a 1024x600 unit, though, if that is a deciding factor. A lot of those are mislisted on AliExpress.

This is my last try unless someone else can think of another reason this is all the sudden crashing, then I will be forced back to 4.2.2.

If anyone has any ideas let me know. This is not the play services crashing error, this is something with the google app.

Thanks for the info. I was looking to see what people say, good and bad. After doing some reading on this thread it seems people don't like the sound and it can't be rooted at 4.4. I'm still not sure the radio has a CAN bus decoder built in. Talking to the Chinese sellers is less then understandable. No one wants to email the manual for some reason. I bought an Ouku (AN-21) almost exactly like this one I'm now looking at, it had the MST chip and android 4.2 (4.1). I had a problem with the MCU file and the seller couldn't get it for me. I couldn't find that file anywhere, so I returned it. It looks like this Rockchip radio is more advanced and more options to tweak.

Hi guys,

thank you for all your heavy work. A lot of Mazda3 users need your collective mind in order to solve a problem that we have in our cars. We have an extra LCD with climate control / radio / clock / etc information. However the special buttons to change the clock and trip information are the part of original HU and are not duplicated elsewhere.

We have a CANBUS adapter supplied by the seller (photo below) but there is no idea how to force this adapter to send the designated signals. Signals are already decoded so I hope it is possible to send them from our HU.

This is on the low speed (125kbit) CAN bus (note some information was found on madox.net). Displaying text requires three consecutive messages.

Message ID 0x28f (8 bytes)

Byte 0: Turns on CD-IN, MD-IN, ST, Dolby, AF, RPT, and RDM.

Byte 1: Turns on AUTO-M, TP, TA and PTY.

Byte 3: Enables intermediate characters between letters: . : ' "

Byte 4: Used for setting the clock. Send 0x90 twice then 0x80 to start setting. Then 0x90 followed by 0x80 to go to the next field. 0x88 changes the current select (250ms repeat rate).

Message ID 0x290 (8 bytes)

Byte 0: Nothing displayed when 0x00. Set to 0xc0 to display full message. 0xd0 or 0xe0 or 0xf0 to display ony the second half (this doesn't seem useful).

Bytes 1-7: Characters to display. ASCII codes from 0x20 to 0x7e (except 0x5c is replaced with the yen sign). 0xdf degrees sign, 0xf0 right arrow, 0xf1 left arrow, 0xf2 backslash, 0xf3 small C, 0xf4 small H, 0xf5 small D. The remaining characters are Japanese.

Message ID 0x291 (8 bytes)

Byte 0: Set to 0x85. Other values possibly used for scrolling?

Bytes 1-2: Repeat of bytes 6 and 7 from 0x290 message.

Bytes 3-7: Remaining 5 characters to display.

A few months back a Ford owner reported a similar problem, unfortunately theres no way round it, its a case of waiting until the manufacturers add full 2 way CAN Bus support for your car or writing some sort of app that enables that functionality. A few months back 2 way CAN Bus support was enabled for some VWs, so they do add support for vehicles as time goes on. Have you tried the latest MCU for your unit ? You could also try playing with the CAN Bus settings in factory settings and try playing with older MCUs - the VW 2 way CAN Bus started working only on older MCU versions (1.77) on KK, bizarrely.
[MTCB Android Head Units Q&A] SantaFox:
Thank you :) Actually I have no idea what to try exactly because I need to emulate a button press from HU to force this canbus adapter to send the signal to the LCD screen. However there is no button on the HU :) And I cannot find any program to communicate with this CANBUS adapter.

Hi there,

My unit is an Erisin ES9746 running KGL1 mcu.

I was wondering if anyone knew when they might update the KGL1 mcu or how to get hold of one.

From the factory MCU I went up to KGL 1.99 and it improved a lot of things vastly along with a rooted 4.4.4. The system operates a lot faster and has less wifi trouble. The problem is however after updating to 1.99 only half of the buttons light up (the left side) and the hardware back button (press power knob in quickly) stopped working. I then tried a KGL4-2.09 but this made the left side buttons light up all the time even when cars lights were not on and also made the key bindings mess up.

I then downgraded to KGL1 1.86 (which i read mentioned fixed wifi issues) and this has restored the hardware power button but still the right buttons are not illuminated. I don't really want to go further back than this so my only option I guess is to wait for an upgrade to KGL1? Does anyone have any inkling when this might be or any other advice?

BT OBD is not working on 4.4.2 roms. It's a known issue. Either upgrade to a 4.4.4 rom or downgrade back to 4.2.2.

I believe they provide similar services and can cause conflicts if they're both trying to do the same thing.

It's a programming step for the ASWC box. Take a look here, starting at page 12. If the #10 Clarion option doesn't work, try the other one.
