Hello KeiserSozeyFr !

I have a Bmw 3 series (e46) and my steering wheel buttons don't work with this V1.1 but the scroll wheel and the other buttons of the front pannel do. Couldn't set the buttons "manually" by introducing their keycode in the settings menu of your app neither.

SWC works with native apps (radio, music player, A2DP player...) without issues.

I couldn't install V1.0 to see if this older version could fix it.

Cheers

Problem with HuiFei 2 DIN Android 4.2 Car DVD GPS Mercedes Sprinter Viano VW Crafter - 2

www(DOT)youtube.com/watch?v=QfGBa9ZC30w&feature=youtu.be

When I turn on first gear the device switches off for a quarter of second: screen goes dark; lost GPS signal.

It happens in the other modes too: radio/music player does not sound for a half of second.

The original factory installed unit had worked well.

It is very annoying when you are driving, especially in a traffic jam.

Seller asked me for picture of main board for my radio issue, it looks like the ribbon between antenna and main board was soldered on, came loose, and then badly soldered on again.

The quality check on the side also has two sets of checks, I'm starting to think they sent me a returned unit.
[MTCB Android Head Units Q&A] kiokio1:
rk3066 KGL

on the factory software it was ok,

on your previous software was ok (downloaded from here 4pda.ru/forum/index.php?showtopic=557670&st=7840#entry36411489 )

Now I do not read the CAN, the screen does not display parking radar, also disappeared parking trajectory grid

whether the equalizer differs only in appearance?

Because I have a feeling that the sound is better than in your previous software

Ah, I see, I did notice they were selling in a lot of Arabic speaking countries.

Nope, its not possible, not unless you wanna try and mod the MCU firmware.

No need, once you install Viper it will apply to all sound on the Android side, it doesnt need to be started early.

Mazda 6 2009 unit

Hi Malaysk.

My unit in May 24, 2015 for 800X480 with regular launcher I have one problem sometime the screen is black I can't see anything but is work I heard music and I can skip song and touch the screen in black. the problem start when I put the gear in reverse the Rear camera doesn't work after that the screen be black to return the screen I slide brightness in notification bar from high to low then back it to high after that the screen work again.
[MTCB Android Head Units Q&A] kiokio1:
MTCCAN swapped applications. I deleted the old and copied the new - not because I installed a system error and do not know how well I did.

I am not sure if this is a problem DPI.

Application (car) is not working. It is this which shows, for example. The amount of fuel, battery voltage, seat belt, handbrake, etc at your previous software, it worked.

It seems that the CAN is not read at all.

I went back to the previous version, but in the current sound is better FM tuner
[MTCB Android Head Units Q&A] tt40:
800x480 system update on a 1024x600 unit?

Would it work?

If it does, can I perhaps expect more of an apparent contrast on the screen? My KGL unit has really bad screen contrast and brightness. I use it mainly to run Google Maps (for life traffic). And Google Maps seems especially washed out and lacking contrast. I was thinking that perhaps making pixels bigger could somewhat improve the contrast.

Conversely, if the above will not work, can I simply change the density in a 1024x600 rom by Malaysk? I was afraid to experiment with that for fear of making the screen impossible to read and thus not being able to reverse this setting.
[MTCB Android Head Units Q&A] jeroensteinvoorte:
Dear Android head unit users. Before buying a headunit for my BMW E46 I have been going throug this thread multiple times. I always liked the idea of having a TomTom navigation and multimedia system build in the dash.

The unit I bought had Android 4.2.2 Jelly Bean on it. At the same time TomTom lanched the new TomTom Go Mobile app. It has the same layout as the TomTom Go we use for the company car. The mobile traffic cams and traffic information. So i downloaded the app.

The Maps for Western Europe van only be installed on internal memory. Not happy it cannot be installed on external storage but ok.

There where soms issues with dispaying the directions. Attached a photo illustrating the problemen. (The arrow is just a blue square).

On my S3 with CM11 (kitkat 4.4.4) the app worked fine.

So today i updated the unit with KGL_4.4.4_800x480_150115_rooted_light_reparted_init.d_v4.2.zip

The TomTom app is working flawless. The interface is ok. Realtime info and all. But now i am unable tot download the larger maps Luke Western Europe, because the internal memory is tot small.

I have looked for options tot move the maps tot external memory, but it seems nobody succeeded by my knowledge.

So i was wondering what tools do i need to change the sizes of the partition of this image, because its unlikely TomTom will come with an update soon.
[MTCB Android Head Units Q&A] agentdr8:
Next and Prev buttons should work, but Back and Menu might not since they're not normally handled by MTCManager or MTCRadio's broadcast receivers. And as far as I can tell, mtc-keys can only launch apps based on their package names, not specific activities or services within those packages.

If you run logcat | grep -i mtc-keys it should show you the keycode integer for the button pressed.
[MTCB Android Head Units Q&A] peti007:
I had the same in my Mazda3 2004. Screen goes black when put the gear in reverse or switch on headlights. After I uninstalled Xposed Screen Filter and disable screen dimming in XposedMTC the problem goes away. I use Twilight instead and works great!
[MTCB Android Head Units Q&A] jeroensteinvoorte:
Thanks for putting me on the right track. It wasn't clear tot me that this also the fix for the new TomTom app. I thought it was for the TomTom 1.3 or 1.4.

Still wondering hoe the system desides where tot put the large maps. Because TomTom just sees it as one folder which is potentially scattered over 4 different storage locations. As this is more a Linux/Unix/Android question I can ask one of my collegues at work.

Thanks for the verry quick response!!!:thumbup:

Sygic repair

I guess what your seller told to you is just crap. Then only know a bit about iGo nothing more.

Please try the following step by step:

force close Sygic via Settings -> Apps

delete sygics data in Settings -> Apps

open a root explorer

navigate to /sdcard

delete Sygic folder

and if you want to be sure you can uninstall and reinstall Sygic

Then start Sygic and download your Data and maps using a stable wifi connection! No 3G!! Use a fixed and fast Wifi if possible.

Whenever sygic gets connection interruptions downloads may fail silently causing problems like yours.

This is what I noticed two weeks ago...

I got a message from DHL. my RK3188 board will bedelivered later on today.

i have been away from the forum for some time and tried the search engine for this thread. i don't know if this question already has been asked:

my headunit is originally RK3066, when i get my RK3188 board am i still able to get in recoverymode in order to flash a RK3188 image?

or do i still need the RK3066 board first to flash a new image?
[MTCB Android Head Units Q&A] dark alex:
Oh this is a good question!

I guess you will be able to get into recovery with the new board. But I don't know.

If not you might need to get that updated also? Or is recovery probably stored on any chip on the SoM?

[MTCB Android Head Units Q&A] dark alex:
To be serious - no.

I did not want to insult you in any way but in fact you did ask if the modification also applies to HD displays on RK3188.

I did just answer exactly what you asked. If you want to know someting else you have to aks about something else.

As far as I know the update you commented on (it's just one APP!!) does not mak any difference between RK's and the reason for the replacement WAS 800*480 so the old ones were for 1024.

thus that does not make sense eighter.

what exaclty do you want to ask?

If you want a firmware modified for a special variant (e.g. RK3188 HD) you should point us/Malaysk to which you mean.

Malaysk, please, can you ask MVG-70 if is possible to add actions like back, home, etc to buttons in mtc-keys and not only apps?

with that posibility i could flash klg3 into my HU that recognize more canbus parameters and remap the incorrect positions for the buttons.

I tried by remapping apps and it's working really really fine! I love it.

[MTCB Android Head Units Q&A] typos1:
Lol, come on think about it !! How could you have 2 boards in your unit when it only has one socket for it ! ?? :)

As DSA says, just swap them over and youre done. (DONT panic if its the wrong screen res for your device, just go into recovery and flash an image with the correct res).

No, it was months ago, youd have to do a thread search to find it.

Its on the flash chip on the SoM !
[MTCB Android Head Units Q&A] dark alex:
Ah so the firmware image itself is also on the SoM? (I mean the android part)?

Do you also know where the RAM sits? Is that also on this board or is RAM on the Mainboard?

[MENTION=6041319]dsa8310[/MENTION]: You had a KGL unit, right? I'm thinking about also getting a KLD-SoM for my KGL als KGL doesn't sell the SoM separately... It's compatible as far as I read on this thread?
[MTCB Android Head Units Q&A] typos1:
EVERYTHING apart from the MCU is on the SoM, RAM on the left, processor on the right, flash above it (on RK3066 SoMs the flash is on the back) :
[MTCB Android Head Units Q&A] DJCannonball:
ofcourse i was not thinking that! i was just worrying about having to flash a RK3188 image BEFORE swapping RK3066 SoM with RK3188 SoM.

but DSA already cleared that out. (thanks)

so that would imply that my new RK3188 board would contain some RK3188 firmware already? or is that a silly thought?

i was thinking that the firmware was flashed to the unit's mainboard, other than a Rk3066 or a RK3188 SoM

[MTCB Android Head Units Q&A] typos1:
Yes, you would not be able to do anything unless you connected to a pc if it had no firmware at all on it ! All the Android firmware is on the SoM, this is what makes these units so good - you can continually update them, the next update is the RK3288 (both Klyde and Joyous have confirmed RK3288/Lollipop development, this chip supports up to 4Gb RAM), after that, the (Octacore!) RK3388 and so on.
[MTCB Android Head Units Q&A] typos1:
As DSA says, they are ALL compatible, I ve also replaced my RK3066 with an RK3188 SoM.

The manufacturers designed it this way for future upgrades and this is how they make their own RK3188 units, everything else is the same, saving production and development costs compared to developing an entirely new quadcore unit.
[MTCB Android Head Units Q&A] doctorman:
now RK3288/Lollipop might be a well worth upgrade from RK3066

RK3188 is tempting but I would not pull my car apart for it unless I need to do it for something else anyway

can we put the name of the people in charge the file server on the first post so they can be contacted directly with the new firmware that needs to uploaded?

I posted a JY update but they tend to get lost in a huge thread like this
[MTCB Android Head Units Q&A] typos1:
"Pull your car apart" ?? !! Where have you installed the headunit, in the engine bay ? !

Its normally a case of a couple of screws to remove the headunit, a few to remove the top panel and 4 to undo the screws on the SoM, it took me 5 mins to change mine over !

There are several people "in charge" of the fileserver, Dark Alex, coudu, agentdr8 and myself all have the password, although I think technically Dark Alex is "in charge" as I think it was him who set it up.

I ve been adding DSA's rooted firmware, coudu adds his own and Malaysk links to his in the thread. I

I ve not really been bothered adding non rooted firmware as there isnt really a demand for it. Did DSA root the 13/05 JY firmware you linked to ? He normally does as soon as someone posts them and as soon as he posts his rooted versions I add them to the repository. If he hasnt done the version you linked to then pm him and ask.

I can decompile the update.img with imgRePackerRK_104

then view the system.img etc with ext4_unpacker and ext2explore-2.2.71

Still relatively new to this unit. I have a KLD 4.4 non rooted unit. I have happily gotten set up with the great knowledge shared in this forum. One small issue I have searched to no avail I was hoping someone may be able to chime in with a fix or if at possible point me in the right direction. The issue is with default music app. No matter what I was listening to previously be it radio, poweramp, iGO, ipod, etc. Every time I start the vehicle the default music app starts after the sd cards are read and mounted. So if I was navigating via iGO and listening to poweramp at shutdown when I start the car again iGO and poweramp will open as will the default music app. When it opens it turns off poweramp and automatically starts playing. Is there a way to stop the default music app from starting automatically? As I said I have searched through this great thread and have not come across an answer.

I have held off in rooting due to the WAF (wife approval factor) unit is in her vehicle she likes it minus this one annoyance. If rooting is only solution that is fine but can you please point me in direction of how to accomplish the stopping of music app from playing automatically. As I said have searched and not come across an answer.
