SWC and CANBUS

Ok so I've been dealing with a problem for some time, but my seller is now stumped, apparently involving an engineer at this point.

Wondering if anyone else experienced the same - I can't be the only one.

I have a KLYDE unit made for a mazda CX-5, and the SWC controls are... strange

Some buttons, when I hit them - get registered as 3 presses. So skipping a song skips 3. Hitting VOL+ increases by 3, etc. Pickup/hangup don't work.

The app for button re-mapping doesn't register any keypresses at all. CANBUS app sees me opening and closing a door. Seller confirmed I got the right decoder for my car, and all the settings are correct, including canbus type in Factory Settings.

Has anyone else experienced such behaviour?

This is what I own :)) Or you need my photo?
[MTCB Android Head Units Q&A] magnetar14:
the unit works its just that its burning out/blowing (burning smell with damage) my car speakers, when i replace the speakers it works just fine, but after a while they get burned out, this because of the short circuit in the connector.

[MTCB Android Head Units Q&A] 5TARKAN:
i have also reported canbus/swc issues with my KLYDE unit for my Mazda 3 BL MPS,

in my case i have "automatic" increase or decrease of volume, without touching any key or button. as soon as canbus is deactivated in the factory settings, this problem disappears.

i also have just following buttons on my steering wheel working:

up/down, vol+/-, mode

not working: pick up/hang up phone and "speak command".

even if my problems are different, i believe its linked to not proper implementation of the canbus interface to our cars...

i have contacted the seller about this and opened a dispute on aliexpress, lets see what happens

where did you buy your device? you have a link?
[MTCB Android Head Units Q&A] typos1:
Maybe you can change the plug ?

But as you can see by other posts a lot of people are having CAN Bus problems with HuiFei/KGL/RM/Klyde units and none of your problems appear to be exclusive to your unit and as yet, nothing suggests that the "GS" version is any different to the other 3 types.

I cant really see what in your connector would be causing a a short circuit or any other problem related to blowing speakers.
[MTCB Android Head Units Q&A] sickbro80:
Thanks, thought it might be the same as mine, buit it's a bit different. here's mine, your the first i've seen that had the same 1.85 software version though.

VAG car has only quadlock plug. No need to swap it. too bad that there is no solution.
[MTCB Android Head Units Q&A] typos1:
You cant identify your unit from that front, that front is used on literally 100s of car stereos from china, Win CE units, Android 2.3 units, Android 4.0 units, Android 4.2 units, its a generic front thats used by lots of manufacturers. Identify your unit by the model numbers and MCU numbers in settings/about.

Well I'm glad to hear I'm not the only one with this issue, and you're on a mazda as well. What year is your mazda? I have a feeling they may have changed something in the last few years - mine is 2014

This is the unit I bought: http://www.aliexpress.com/snapshot/6125852577.html

There are at least four other sellers though that sell identical unit.

Today I tested this new version but results are negative:

1) I don't know why you assigned to Play/Pause button keyCode=1000? I know that Play/Pause keyCode is 3. I corrected this in the Settings and rebooted my HU.

2) Now Play/Pause button works with 3rd Party media player (I use "Neutron Player"), but it works only as "Pause", not "Play". If currently playing music, that this button acts as "Pause". But if the music is paused, this button has no effect.

3) If my music player works in the background and music is playing, that this button stops the playing and shuts off the music player (player's icon disappears from status bar).

Okay, got my hands on a PSU, wired everything and the same thing that happens at the car happened here. LEDs turn on but screen doesn't and unit doesn't seem to boot.

I opened it up to see if I had the broken clip mentioned on page one but apparently not. Everything seems to be in order and I don't know much about electronics so I don't know what else to check. I attached two pictures. Anyone have any ideas as to what to check?

Thanks
[MTCB Android Head Units Q&A] bcrens2:
Also now it's not booting at all any more it just stops at the first screen
[MTCB Android Head Units Q&A] Telemachus:
Did it stop working after you removed the screen and reattached it?

Does the screen power on at all?

If you attached the ribbon cables incorrectly, you can actually short out (destroy) your screen. You'll still see some light/response, but that is about it.

You'll need a replacement screen from your manufacturer.

Car Battery Dead

I installed my radio on Saturday, and my car battery has died 3 times since. once I left the dome lamp on. 2nd time headlights. Now it just dies.

Had the battery and alternator checked, and they are fine.

I cut the standby time down to 30 seconds.

Hopefully its not my HU!!

[MTCB Android Head Units Q&A] vdubskey:
What kind of PSU is it? A pc supply? If so depending on how many watts it is and how you wired it you might not actually be getting 12v. My modded pc PSU only put out 10v so I went with my other power supply. If you have a multimeter check your output and verify you are giving the head unit enough juice. The LEDs only need 5v so they will light up no problem.

Also double check the wiring at the head unit. My units sticker showing the connections was totally different then the wiring harness. I could have easily fried my main board if I didn't notice that.

Yea but I will get charged for using my phone as a hotspot. I fly under the radar using Bluetooth tethering. Anybody have success with a USB Bluetooth adapter? Any conflicts?
[MTCB Android Head Units Q&A] agentdr8:
Not possible either, without kernel source. Unless you can find a usb BT adapter that uses the same chipset as the BC5/BC6. Even then, I don't know how you would disable the onboard module so android uses the usb adapter.
[MTCB Android Head Units Q&A] Nightwchtr:
Check too see if power from the board is reaching their screen with a multimeter. If not could indicate a bad board or just a bad power supply

What happened to the miracast, mirrorlink app and the option to change the external colors of the buttons. They aren't showing in the settings buttons anymore??
[MTCB Android Head Units Q&A] flydeep:
I think XposedMTC has a bug or a possible memory leak. I just had only Navigation defined in the 'mode' alternate options of XposedMTC. After switching 3 times between Navi and Music, I get a never ending boot logo and it just stalls there. The only way around that is to turn off the power and on again. So I have nothing defined for 'mode', so essentially it is just a switch to music hard link steering wheel option. It works for now since I have a hard "Navi" button on the HU.
[MTCB Android Head Units Q&A] hadjistyllis:
Try to enter to recovery through hardware button specjfied for your model before do anything else.
[MTCB Android Head Units Q&A] agentdr8:
Try assigning the preferred video app to something (anything) if you haven't. Even though it's not in your rotation, there's a known bug with it being left as the default. And if that doesn't resolve it, then you've hit the other bug with modeswitching, which was keeping track of which source is the current one. The whole modeswitching is being rewritten from scratch for the next version, but there's no ETA at this point, as a number of work-related things have come up, and they have priority unfortunately.
[MTCB Android Head Units Q&A] flydeep:
agentdr8 - I have the default video app set to poweramp. If it makes a difference, my Navi app is Waze and default Music app is Poweramp.

I have tried to buy from german IP, but it didn' t work. I'm waiting for the answer from the developer.

I think, technical possible to connect two aerial to USB dongle. I think it's worth a try.

I love the MTCradio app for receive the FM station. The UI of the wavesink app doesn't user friendly, that I only use this for DAB+ receiving.

My plan is, that I connect the stock aerial for FM receiving only to HU, and DAB+ aerial only to the DAB+ USB receiver.

This adapter is good for us:

Any chance to get a un-themed Malaysk-ROM ?

[MENTION=3590033]Malaysk[/MENTION]: Just a simple question: Is it possible to get your ROM/Firmware with unmodified pure stock theme?

Personally I really like all the functions of your ROM, but (sorry this is just my taste ;) I dislike your theming. The EQ buttons, the green SystemUI theme, the Living backgrounds and so on....

Well I know I can replace some apps with non-living content, but I would really prefer an unthemed ROM, if possible.

Learn to trim your quotes. Quoting a multi-page post only to add a (top-posted, no less!) 1 line reply is why this thread is almost 3000 pages long.

Too bad these things don't use a operating system like Android, where the user can change things themselves. Really, if you want an "unmodified pure stock theme," just load up one of the stock firmwares which is floating around.
[MTCB Android Head Units Q&A] Tumke32:
Yes it works, but i think this one will work better because its has less power consumption:

http://nl.aliexpress.com/item/2014-...909.html?adminSeq=202513811&shopNumber=520062

It needs an other aerial to use it in a car. something like this:

http://nl.aliexpress.com/item/Digit...o-Antenna-Aerial-Amp-Booster/32263242564.html

You also need a converter because most of the connection of these aerials a different then your usb dongle (thanks to ktibor69).

Ive been using coudu ROM for quite some time as it was working perfectly but just one thing bothered which was the screen somehow flipped so if icon was on left i had to click on the right of screen to click where the icon is (On the left).

So iv been reading and following Malaysk ROMs and thought ill try it but now im getting few problems with apps that worked how I wanted on Coudu Rom.

1.) Poweramp has to scan sd card whenever headunit switches on, bit annoying as u lose your last track and I have to wait for hundreds of songs to load (Coudu ROM played as sd card was still loaded)

2.) Car Service doesnt work as It wont let me map my buttons for my steering wheel. The next and forward buttons are reversed. Car service allowed me to map them properly and ofcourse use with poweramp. With Malaysk ROM it doesnt work

3.) Poweramp toast just immediately shuts down when booting.

Other than that Malaysk ROM is very nice n fresh with loads of features and settings compared to Coudu ROM but these issues wants are leading me to go back. Anyone perhaps know why before I revert back to Coudu ROM

I updated to:

- update_4_4_4_800X480_RK3066_27_MAL_06_09_2015

- MCU_KLD_2.64_Musik_darkleo

Did you perform the factory reset (partition format) after flashing the Malaysk rom? It's important, as the partition layouts are likely different between coudu and Malaysk, and not doing it will result in all sorts of odd problems.

Has anyone noticed Google now voice commands crashing consistently everytime? I have a error dialog box pop saying docsdk error. In some instances my DSub music player starts playing automatically as soon as the voice commands are entered. My default player is Poweramp and i use Dsub to stream only from home server whenever needed.

What app do you use to initiate a call from the HU while driving? The bluetooth application can dial a call connecting to the phone but I do not see any option for contact widgets. The easiest way is to find a call from the call log and click on the call. No quick way to call someone while driving. Creating a contact widget and trying to call a number gives me an option to chose a default player of Titanium Backup or HeadUnit!!

I am trying to flash malasky rom 4.4.4 1024x600 RK3188 09_09 on my stock JY radio. I put the update.img on the root of my gps micro sd card. But when i boot my radio up it does not recognize it. I probably am doing something wrong but not sure what. Thanks
[MTCB Android Head Units Q&A] rhacy:
I'm sure there's an easier way, but I usually root the HU first by going into Settings->Factory Settings, and enter *#hct#root# as the password. Then I download and install Quick Boot from Google Play, and use it to boot into Recovery. Once in Recovery, you can use your Power - Volume Button to scroll to the appropriate image location and then press the Power Button for a few seconds to start flashing the new image. If you're switching from a stock ROM to a custom, make sure to select the option with the clear feature. Once you have Malasky's ROM installed, make sure to go to Settings, Restore and Reset, and do a reset to the factory with a check mark to delete all data from the SD card. This will give you a nice clean start with the new custom firmware.

Hope this helps...

[MTCB Android Head Units Q&A] rhacy:
My Joying JY-UQ124 HU is on the latest Malasky ROM, and it saves my WiFi On setting, and the built in Music or Radio remembers my last song or station and starts to play when the system gets through enough of the boot up process. I'm guessing you may either have the wiring wrong - (BATT+ and ACC tied together or hooked up backwards or ?), or you may need to flash again and make sure to select the clear option in recovery to partition correctly. Do your preset radio stations stay saved on the next boot up? Again, I'm just guessing, so hopefully someone that has run into your issue will post with their fix.

Thanks for posting easier recovery options. Cheers!

Your RK3188 HU will only start playing music once Android has booted up (approximately 15 seconds or more after boot starts). My older Windmark Android HU with the Mstar processor starts playing right away at boot, but these Rockchip units do not at this point. That said, I think Rockchip is designed for generic general use and not specifically designed for automotive use. In turn, there's a boot up delay as well as a higher amperage draw on standby, so the system needs to fully shut down in order to avoid draining your car battery over time.

Best to all,
