hello , i use malaysk rom august , i have a question , the auto light it works i think with pbx , but i need a lower light -1-2-3 level something like that :) because i drive night and it damage my eyes :(

I use the ones marked with sleep and redesigned sound processor from darkleo.
[MTCB Android Head Units Q&A] TheOnlyTy:
I too am trying to work this out. I have the JY v2.73 MCU on mine, the sleep time makes it a pretty sucky stereo. If you want to get in the car and navigate you have to site and wait for it to boot. I would happlly donate to someone if they succeeded in getting 24 and 48 hours added to the sleep time. Next need to try and fix crappy bluetooth :(
[MTCB Android Head Units Q&A] agentdr8:
The "sleep" mode on these headunits isn't a traditional sleep like on mobile devices; the amp still draws power, even when the screen is off. It's been discussed before in the thread.

I don't use the built-in BT any more since even with separate mics the call quality wasn't up to my standards. I use a Parrot CK3000 to handle my calls, which when also paired with Tablet Talk, integrates fairly well with the headunit to mute/pause other audio sources.

You can't change the BT card out for something else afaik. The only supported modules are the BlueCore BC5 and BC6.
[MTCB Android Head Units Q&A] TheOnlyTy:
I was under the impression the draw was something like 500ma or something similar. I work with a guy that has a different android head unit and his is set to sleep 48hrs, duel battery system so the I am confident i could run in for that long no worries.

On my other Unit i can Change the Color of the Buttos but where is normally the menu to Change the Color? I cant find it (maybe i am blind ;) ) , like i said i use Malay´s ROM (last build).
[MTCB Android Head Units Q&A] agentdr8:
I found this post from way back when. Assuming your battery is in good condition, it's probably feasible to do a day or so of standby. The problem is most car batteries aren't cared for properly, and the charging cycles of short trips, combined with running accessories while the alternator isn't charging tends to lessen the usable life over a short period of time. Imagine the amount of internet rage if they offered a 24 or 48h standby option, and people with less-than-ideal batteries come out to dead cars in the morning. Not that I'm convinced the Chinese mfgs even give a rat's ass what their cred is like once they've made a sale, but maybe they're just playing it safe (or maybe Chinese cars have tiny batteries with less capacity)?

I would hope that before they offer longer sleep periods, they should consider enhancing the power management of the unit while in sleep; turn off the amp fully, turn off the 5V bus, etc.

If you forget to give permission to 644, the unit will not boot and will have to flash through recovery.
[MTCB Android Head Units Q&A] TheOnlyTy:
I agree, people with you batterys would suffer (and learn). But isnt that the point of getting an android device, freedom to choose to do things that you may regret? haha. Plus they could just but a bumch of warnings up. For me, i will consider replacing the device if i cant work out some way of getting this to work. Waiting for boot defeats the purpose.

Hello agentdr8

Thanks for your advis regarding the headunit poor Bluetooth mic , and your workaround.

I just want to be clear about your suggestion please, so I need the Parrot hardware fitted in the car, then I install tablet talk on the headunit and pair the Parrot to the headunit , and then setup the parrot within Tablet talk, but do not pair the parrot to my phone?

Is this correct please, thanks
[MTCB Android Head Units Q&A] Rackers:
Can anybody assist? I've got a KLD unit with latest Malaysk firmware and MCU version 2.55.

I know it has been discussed before but I cannot find a solution which works.

I cannot get the key light illumination to stay on at all. When I select the option in the 'Element' setting it comes on for about 3 seconds and goes off again. I've been in factory settings and ticked the key light button which also has no effect. The lights come on at boot for 3 seconds and then they are off again. Using the headlights, etc. has no effect either. I've upgraded and downgraded to different MCUs but still have the same problem. Does anyone have any ideas what the problem could be?

Thanks

My unit draws around 120 mA when in "sleep., and around 1 A when on. So, let's call it 3 AH per day when sleeping. A car battery in good shape has a capacity of 10 times that.

Extract the app using Apk Extractor and re-install it after youve flashed the new ROM ?

Its not just the USA, AF doesnt work properly anywhere

Not perse, I just asked for an RK3188/1024x600 update months ago when there was that RK3188/1024x600 res problem when people with RK3066/1024x600 units upgraded their SoMs. For some reason it just wouldnt download, so they sent me it on SD card and they happened to add RK3188/600x480, RK3066 800x480 and RK3066 1024x600 updates as well, so I uploaded them to the fileserver. The date was 10.08 on some, 2 did not have a date (I labelled them all 10.08 though). Dont know whether the update you just got is the same as the RK3066 800x480 version I uploaded or whether its an entirely new version, have you compared them ?

The big problema if when sleep and when working. It's more than two hours.

We have the MCU code? Is possible to get this code? Maybe I can do this or is only possible with reverse engineering method?
[MTCB Android Head Units Q&A] vdubskey:
I wouldn't recommend it just as other people have due to draining your battery over time. But if you really wanted to, you could use tasker to turn the screen off after a certain time and set the device to always on. Then use your timer on the ACC line like you mentioned. I don't mind the 20 second boot time myself. My first carpc took 50-60 seconds for a cold boot so consider ourselves lucky Lol.
[MTCB Android Head Units Q&A] dhmsjs:
HU currents

For those who don't like waiting for the unit to boot, just adding a switch to power the ACC line directly from 12v works pretty well. I installed a pushbutton switch on the dashboard. With this I can keep the unit on if I want without having to keep the ignition key in the ACC position. It's not on a timer but does that really matter?

If you're worried about battery drain here is what I measured during bench testing. This is a KLD2 quad core 800x480 screen (Pumpkin C0235).

ACC off: 10mA

ACC on, no display: 130mA

Display on: 570mA

Radio on, low volume: 700mA

Radio on, high volume: 720mA

All of these are without a wireless backup camera. A wireless backup camera added another 400mA
[MTCB Android Head Units Q&A] agentdr8:
(repost of what was replied via PM)

Parrot is fitted in-line of the headunit wiring. It has its own amp and line-level speaker outputs, so it can actually take over audio output during a call.

You pair your phone with the Parrot, and not the headunit. Tablet Talk gets installed on both your phone and the headunit, and communicate with each other using the wifi hotspot on your phone. In the app settings, you enable phone/dialing support. When a call comes in, Tablet Talk on your phone notices this, sends a prompt to the app on the headunit, which prompts you to answer it. When you do, it sends that back to the phone, which then connects the call on the Parrot, which automatically takes over the audio.

The only downside to the arrangement is that you'll have a separate physical volume control for BT calls. But for me, the call quality was infinitely more important, so the addition of the CK3000 controller module was no big deal. I mounted it out of the way, and rarely have to adjust it. But as a bonus, you now get real-time text messages on your headunit, and can reply to them directly. Of course I don't recommend trying to do this while driving, but it's nice being able to read texts while on the road. You also get access to your phone's Contacts, so you can dial by # or T9.

One thing you'll want to do if running a custom rom is use the PCV app to early-start the Tablet Talk service on the headunit.

Oh, and I also automate the wifi hotspot activation using Tasker. When my phone connects with the Parrot, it switches to LTE, enables hotspot, and opens up Tablet Talk (I don't keep it running on my phone all the time).

You can also get a 12VDC UPS and a separate SLA battery (or plural) to keep the headunit on for days, without worrying about draining the main starter battery ever.

Slightly OT: were you on mp3car.com by any chance [MENTION=4218901]vdubskey[/MENTION]? I too had built a carpc way back when....these headunits seem so "advanced" in comparison. Lol.

Hi everyone!

Have modded the volume bar for my taste: bigger, at the bottom, semitransparent, styled like on TV and other AV equipment.

Default one was barely visible in sunlight.

The original file was taken from Malaysk ROM for 1024x600 and JY style, dated 2015-08-13.

If you like it, please download, unzip, replace file under \system\priv-app and reboot.

To be on the safe side, make backup of your file MTCManager.apk, there is always something wrong could happen :)

Changing boot animation

Hello,

Can some one explain this better (changing boot animation)? I don't understand the steps I need to go thrugh:

1. It is necessary to put the Root - What does this mean?

2. Using Root Explorer or Total Commander

3. Go to the radio in the Settings -> factory settings -> enter the code 126 -> select the animation. (Usually it is the second of two full-time). After rebooting, you should see the dancing Android'y - What is "(Usually it is the second of two full-time)"

4. Unrar the downloaded file ( bootanimation_dancing_droids.zip do not touch )

5. Next, copy bootanimation_dancing_droids.zip file below the animation to a folder \ system \ mtc \ and give rights 644 (ie rw-r-r) - What does it mean to give rights 644?

6. Reboot and enjoy.

Sorry for google translate !!

When I decompile and recompile with advanced apktool my radio does not install the application (root explorer)

I have the same problem with MTCRadio5.apk of Malaysk of refusing to settle without having to change

I manage only to install the radio application of ktibor69

If I extract the original application from my radio (MTCRadio5.apk) I decompile and recompile, and impossible to install !!

If I decompile and recompile the Ktibor69 of this radio application will not install either !!

Someone to help me ??

Thank you !!!

[MTCB Android Head Units Q&A] dadd10:
Download the attached radio app by ktibor69 and use it to replace mtcradio3.apk in \system\app with root explorer making sure you save a copy of mtcradio3.apk onto an sd card / usb as a back up. reboot the unit and it will update with the new radio app, you will have to reinstall a link to it on your home screen.

[MTCB Android Head Units Q&A] gurumaia:
Ok, I managed to disassemble the dashboard and check all the connections. Since this unit comes with the wiring specific to this car the connections looked good, except for one thing. The guys at the store did something weird. They cut the wire labeled BRAKE and connected it to the GND wire. As a result of that, the GND wire seemed a bit damaged. I found the diagram for this unit online but I can't post links yet. Googling "joyous android diagram" yields the result.

The dude told me he had wired it so that it would shut down when you turned the car off so as not to drain battery, but as far as I understand it, this unit already does that. I don't know if this connection is what he meant or if it's something else. I also heard before that people did this in order to allow video to be played with the car in movement. I'm not really sure what he tried to accomplish, but I'm thinking this is the cause of my issue.

I disconnected the brake wire from the GND wire, left the brake disconnected and tried but I got the same black screen as before. I'm not sure where the BRAKE wire should connect to, so I don't know how to fix this. Does anybody have this same unit to check where the brake wire should connect to?

Thanks!
[MTCB Android Head Units Q&A] dadd10:
The "brake" wire does indeed connect to grnd so that you can view videos whilst driving, not a practice I would recommend :) I assume you would need this though if you had headrest monitors.

[MTCB Android Head Units Q&A] gurumaia:
I see. I don't know if you saw my first post explaining my problem, but the only reason I disassembled it was that sometimes the screen was not turning on at all. I'm thinking this is related, would you agree? If I leave the brake wire disconnected, would it make the screen turn off or would it just disable video apps (DVD, YouTube, etc)?

Thanks
[MTCB Android Head Units Q&A] OneCheekyDevil:
The brake wire is connected to the handbrake switch. You're not allowed to watch videos whilst in motion. Some people get around this restriction by grounding the brake wire to have videos whilst driving (myself included).

The brake wire isn't the reason to your problem unfortunately.
[MTCB Android Head Units Q&A] TheOnlyTy:
No reason it needs to be this way. Pretty sure most people would stick it over 2hrs if they were given the choice.

Anyone have issues installing a klyde unit into their Hyundai sonata with stock dimension amplifier and getting no sound?

I'm trying to figure this out..

I have the can bus connected, the wires connected (there's no amp trigger) .. not sure if there's a trick to initialize the canbus like the Metra boxes..

There's sound signal coming out of my rca cables but I can't use them with my amp

JY Ford focus

Hello,

I have few questions about the installation of a JY HU in my Ford focus 2 II 2008.

1. The HU does not start if the canbus decoder is plugged and the acc wire is disconnected. When the acc wire is connected and the canbus decoder disconnected, the HU starts and shuts down normally. Is it normal? Is there any issues to use this configuration?

2. The steering wheel control does not work in the configuration explained earlier. But if I switch off the head unit (the HU is in sleep mode then), connect the canbus decoder and disconnect the acc wire, the steering wheel control is then working normally. But the HU will not turn if it switches off completely. Additionally the dashboard light will not switch off if the canbus decoder is plugged.

What would you advise me to do?

Thank you in advance for your help.
[MTCB Android Head Units Q&A] gurumaia:
I know about this restriction in most head units, but I remember seeing an option in the settings menu that toggled this behavior, so I thought it wouldn't be needed. Anyhow, I'm now thinking either the problem is in the gnd wire or the unit is defective. The wire didn't seem to be in too bad shape, but it was stripped (is this the correct word?) in order to connect the brake wire. I have photos but I'm not allowed to post them here.

Does anyone have any ideas?

[MTCB Android Head Units Q&A] swanie2000:
Hi,

I don't remember seeing your first problem (post), but I may have an idea as to what you are experiencing. My problem started a few months ago, after an update. Sometimes I have a blank screen. I have been able to sort it out as to when and what happens.

My screen blacks out, when I pull the car from park into drive too fast. At first I believed the reason was because this action pulses the reverse wire. I have a switch on my dash to toggle the rear camera on whenever I want to. Sometimes I pull a trailer, and like to keep an eye on it. Anyway, whenever the screen goes black, all I have to do is toggle the switch on the dash to on and then back off, and the screen on the HU will come back on like normal.

I have been doing this for a few months now. The last update help quite a bit, but it still happens every now and then.

After some more thought and digging into the wiring diagrams, I realized that my canbus decoder was actually responsible for turning on the 12vdc signal for the HU. I don’t blame the canbus decoder, as it only switches the 12vdc signal on and off. I do think this may be happening too fast for the HU to “SEE” it happen, and the HU gets confused until I manually(and much more slowly) hit it again with 12vdc from the switch on my dash. I have given some thought to a capacitor on the reverse line to ground, maybe a 100uf@25vdc. Something big enough to slow the 12vdc signal down so the HU can respond to it, but not too big to hold the reverse camera image on the screen too long.

I do not know if this is your problem or not, as I have been reading this forum since about page 600. That being said, I only remember 1 other time someone mentioning his/her screen blacks out occasionally. I hope this helps? Maybe another member here is also experiencing this behavior, and just hasn’t reported it to the community? I assumed this issue was just my trucks fault, and didn’t feel it belonged in this thread.

Cheers!
[MTCB Android Head Units Q&A] gurumaia:
Thanks for the input. I think that while our problems look similar, they have different causes and symptoms. With me, it's not the shifting from park to drive that causes it. It simply doesn't turn on when I put the key in the acc position (or when I start the engine for that matter). It'll stay off forever if I leave it alone. The only way of getting it to turn on is to hit the reset button. It usually takes a lot of tries. Also, once it does work, it stays on and doesn't show any problems.

But I think I figured out a behavior that might help me troubleshoot it. It seems like the issue only manifests after I leave the car parked and turned off for a while, more than a few hours. And then, pressing the reset button right after starting the car usually doesn't help. But if I leave it alone for about 20 minutes and then give the reset button a try, it works. It did once today anyway, on the first try. I'll try again tomorrow.

So this got me thinking it might be related to the amount of juice the car's battery still has. Perhaps when the car stays off for a while the juice drains a little and this lowers the voltage that is delivered to the HU. After driving a while the battery is re-charged and everything goes back to normal. But now I'm stuck, I have no idea how to confirm this theory or if it makes sense at all.
