[MTCB Android Head Units Q&A] Enc0der:
Hi, I've finally figured out the multiple buttons bug!

Every time I press the MEDIA hard button to load the music app, the number of registered clicks from the next/prev/play/pause hard buttons is increased by one!

I'm using the latest XMTC and nothing else, Headunit is disabled.

PlayerPro as my default music player (but it's the same for all).

First boot:

I press the MEDIA button to load PlayerPro.

Next/prev hard buttons works great.

I press MEDIA again (because I switched to another app, or home, or whatever).

Every next/prev button click is registered as TWO clicks.

I press the MEDIA button again.

Every button click is registered as THREE clicks.

I can even click multiple times, if now I'll click the MEDIA button 3 times in a row, from now on every next/prev hard button click will register as 6 (3+3) clicks!

Existing the player doesn't help, the only way to reset the "counter" is by restarting the unit.

Any help? :)

thanks!

HI forum

My car is Chevrolet Cruze 2011

I am living in Turkey.

And i bought from Hong Kong by DHL in last mouth.

This my device

http://www.aliexpress.com/item/FREE...apacitive-7-2Din-TCC8935-Dual/1721035711.html

And

Does not turn on at the moment

I ask seller

And he say

"You must be update it."

But i downloaded update.img and umc.img .and i put to navigation MicroSD card.

But big problem my device doesn't recovery mode.

Maybe it is be brick :(

From my car

https://m.youtube.com/watch?v=YersbfZXP4w

I tried all combinations.

But its not.

And i havent miniusb front side,you know ahead only have normal USB input for mp3 or mp4.

I tried connection with both sides man-usb, but my laptop did not see the device.

I asked to seller again, I am waiting for his reply.

I am so unlucky. everyone's problems are solved in this way.

I opened to the back of the device. I know a little bit of electronic-work. but I did not want to spoil more digging. I saw the back of the chip rk3066. I do not understand why does not enter recovery mode.

Even; i tried and i make with boot-Microsd by PhoenixCard but it is not.

If you asked to me. how this came to be.

I did not do nothing my friends. I brought that car operate normally and i saw Andoid has failed on screen. You know "com.andoid.bla bla bla ....." . had been previously. I did turn off-on and was recovered. Seeing this same error, I thought about turning the device off-on again, but in logo stayed. :((

I taken new video

http://youtu.be/Cuj6YkkcYFU

I will be crazy

Can anyone help me?

Please...

Anyone else have an issue with the GPS overlay on radio? The sound fades but the voice is barely legible, I tried to adjust the volume of the mix ratio but it only seems go effect in music playback and not fm
[MTCB Android Head Units Q&A] typos1:
Heard they were developing it, didnt realise theyd do it so quick, but there again it wasnt hard really, was it ?

I like the solution theyve chosen though, just using the phone and mirror linking it, I was only thinking the other say how the HuiFei units could work just as well with the Android part missing just a small board interfacing with user's phone using mirror link or usb to the headunit and becoming the headunit's brains, it could still work the same apart from that, the MCU would still be there, the radio, amp etc. Whats the point in having 2 computers when one will do ?
[MTCB Android Head Units Q&A] xrapidx:
Check in the factory menu, there's an amplification for the various components.
[MTCB Android Head Units Q&A] kwalsh24:
Tried that, didn't make a difference.

When I am in the music app, and the GPS notifies, it will dim tthe music volume and the GPS voice will be nice, clear and loud.

On radio, the Gps notifies, it will dim the music but the GPS voice will be as dim as the radio is, to the point I nearly blends in.

Its almost like the mixing volume doesn't carry over on the radio app but does on the music app. Wonder if flashing to the firmware posted on the first page will do anything.

Attached is the mixing settings I have which makes zero effect on the radio, bit really effects the music app.

I even went as far as adjusting the radio in the factory settings but that did nothing at all.
[MTCB Android Head Units Q&A] xrapidx:
Ah, can't help there, cause my radio doesn't work :(

Makes me think though. I wonder if downloading the software in the OP and reloading will help? My versions are exactly the same, any thoughts?

I see the unit has iGo installed, I'd like to test it before buying it (we have offroad maps here specifically for iGo)

But when I open it it doesn't full the screen, is there a fix for that? (it basically looks like its pushed down by the status bar at the top)

[MENTION=330759]kwalsh[/MENTION]: I suggest you first upgrade the soft/firmware. It's impossible to compare the behaviour of apk's on different flavours of the software. It makes things more difficult for the makers of the apk's too (comparing apples with melons). Maybe the makers of the apk's could also specify with which version(s) of software they tested things (if possible), I think it would make things less confusing. Also the messages about complaints of not working would be minimized this way, only the messages of people finding out it works on other software flavours would increase. Trying to make things less confusing for all of us.

[MENTION=344039]paki[/MENTION]dermo: Can you give me (a hint or) the specs of the AVD you made in Android studio, or do you connect your device with a usb cable to your pc/laptop to test your newly creates ui for the radio apk? Programming is nothing for me, but changing a ui or a entire theme might be doable for me...

I have a pretty decent soldering setup - but I think I'll take it to be done if it comes to that, my hands are not made for fine work.
[MTCB Android Head Units Q&A] kwalsh24:
The only thing I see with this is, my radio says I'm already running the current version that's listed on the first page, however I also read that people said in the update that's listed on the first page, that the radio apk stored stations by name vs frequency. Mine seems to not do this, it just lists the last portion of rds that was displayed last, however maybe that's normal, I'm not sure

Hi, i am car DVD reseller, usally i work with win ce units because the are stable and not had too much problems (my concern is aways canbus), but I see that specs of android 4.2.2 car DVDs are much better, including fast processor, capacitive touch, software like android and another's. So I decided test it on my own car: Golf mk7, contacted this company: Shenzhen Kai Ge Le Electronics Co., Ltd

They tell that sell HUIFEI car DVDs, talked on skype with bingo Qiu, her was honest, told that had too many problems with canbus functions on golf 7, it was about 3 month ago, I keep contact if it was fixed, aways her said that not yet, but today said that it is fixed and it will arrive on 15 July (next month), as told never seen any android 4.2.2 running interface to show fuel consumption, door status, parking, etc, aways see same android 4.2.2 pictures,never showing car functions.. Bingo Qiu told me that will send me pictures of these user interface (related advanced can bus functions) next moth.. My mean question is: somebody here have advanced canbus functions working with your car ? Like fuel consumption, door status, ESC ON/off, etc ? Have an picture of this car info running over android car DVD ?! I am curious about that because I already searched thousands of images on Google and aways see same interface without anything related canbus car functions..

Another doubt is: it work with waze ? Somebody have huifei unit without any problem running perfectly ?

Thanks
[MTCB Android Head Units Q&A] gy_ro:
I already replaced the original with the blue one. I can however put the original back in place and see if I can confirm your findings. It will be sunday however ... I know that the blue one stores the names if you store the channel when RDS is working (receiving the channel name). However if you push a button to select a station and RDS is not there at that moment, the name on the button is replaced with the frequency.

Hi guys

Some days ago im bought HuiFei KGL-8802 for my Kia Sportage 2013.

Can i ask some questions?

Is this unit support brightness decrease when i turn on dipped lights on car and lights of all buttons on DVD is ON ?

Which exactly screen resolution on this system? My seller says me that 1200x600 but im red that usually installed 800x600 screens?

Are this system is stable working?

Now im use system from CUSP (its piece of sh....t ) always small problems.....

What is the name of tuner installed in HuiFei? QSD-RT-L93 ????

Thanks to all for answers.

Can someone please upload somewhere the iPod.apk from the unit? I see that on some units this App which controls the iPod/iPhone is missing. If someone would copy it from the unit and post here the link I would be very grateful. I will be the first who will test it.

Thank you in advance.

BTW I'm guessing that the app is in " /system/app/iPod.apk " or something like that.
[MTCB Android Head Units Q&A] pakidermo5000:
I created it myself. The closest I could get to reality was using:

1- Take the Device Nexus S and modifying it as:

Screen size 7"

REsolution 505 x 800

Size= Large

Screen Ratio= Long

Density= hdpi

Buttons= hardware

The one above is not the real size, but I think the proportions are good to fit my headunit.

Another option I tried and worked quite well, used the real size (resolution) 864x555 (but you have to substract 45px for the upper bar, so 864x510

2- I created another one from scratch

Screen size 7"

REsolution 510 x 864

Size= Large

Screen Ratio= Long

Density= hdpi

Buttons= Software (if I choose hardware it does not look good)

Hope it helps.

On some pages, for example in the description of the HuiFei units on Alibaba it says that it supports iPod control I tought that it actually does. On older units (Android + WinCe) this options worked very well. Can someone hack it to work on this new units with Android 4.2.2?

Mic Fix on Eonon Ga-5153 Kld C-32 transistor no wifi no bluetooth

I have tried the external Mic fix on my eonon KLD ga5153 by soldering a external mic directly to the blutooh module and removing the transistor C-32 in order to separate the internal from the external Mic circuitry , but after removing the c-32 transistor i have lost wifi gps and bluettohh

so this fix to separate the internal from the external mic in this unit is not by removing the C-32 next to the blue-tooth module , i had to solder back that part C-32 to regain wifi gps and bluetooh again

they must have changed the internal parts on this unit

i have upgraded from factory 4.2.2 to 4.4.4 Kitkat from Condo's KLD_4.4.4_800x480_150416_rooted_light_reparted_init.d_recoem_v4.3

it works great along with TOMTOM from the SD 2 card after the recovery.sh fix

The only problem is the blue-tooth "hands free call" the Mic quality in this unit is terrible it just sucks " having to use the internal mic our external mic is to low voice and to mutch noise.

Thank you four all the resources about this car units on the forum

Pardon my ignorance. I have downloaded multiple update.img files, but noticed that all the newest files are made up of a part1 and a part2 zip type file.

File is broken" I have downloaded JY,KGL,KLD and KYD for KK4.4.4 800x640 files with the two parts and i get the same error with all the part 2's.

I now have a issue with the "KLD2_KK444_800x480_150202_root_mod_boo_201504-12_v1.0.0" update.img i installed. The installation went smooth and when the unit rebooted it will not go past the start-up screen. I have tried manually to get into recovery to try a different img, but the "hold reset and power button for 5 sec and release reset button" method doesn't work.

What am i to do now, i have not had this issues before when updating the img file. My MCU "MTCB-KGL4-V2.47" file works fine with previous updates so i do not think that's the problem.

[MTCB Android Head Units Q&A] agentdr8:
That's very bizarre behavior, as I'm not keeping a count of button presses or anything like that. It's just broadcasting an intent for the selected media player. It's possible that something is blocking those intents, or they need to be sent in an ordered fashion instead of just asynchronously. IIRC, your swc is done via canbus and not the resistive wires, correct?

You mean match the button backlight intensity/brightness with the screen backlight? There's probably a way to do that.
