[MTCB Android Head Units Q&A] 7floor:
Thanks, but you probably missed one important thing I wrote: "The date/time is not preserved after reboot when power is connected for sure, ignition is ON and if you wish, the engine is running. There are many ways to reboot the device. For example, I use reboot function found in Xposed Framework."

Once again: The ignition is ON and head unit is powered on and working. I just reboot the device by software, not powering it off. After reboot, the date/time is not preserved.

And one more detail: I have ACC wire to the unit disconnected at all, as it turns on/off via CAN-box (VW version).

So then maybe I have a different issue. Mine loses date/time even after software reboot when ignition is ON all the time.

How and what I have tested:

1. Make sure that car itself doesn't go to sleep and doesn't disconnect main power to head unit for at least 1 minute after I pull the key out:

Set sleep timer of head unit to 30 minutes. Pull the key out. The head unit goes to sleep. Wait 1 minute. Put the key back and turn ignition on. The head unit wakes from sleep instantly. This means that during that 1 minute it had the power.

2. Prove that after shutdown and then boot, the head unit doesn't preserve the time:

Set sleep timer of head unit to 30 seconds. Pull the key out. The head unit goes to sleep. Wait 40 seconds (test above proved that car doesn't cut the power during this time). Put the key back and turn ignition on. The head unit starts with cold boot. After boot, the time widget on desktop shows 03:00. My timezone is set to UTC+3, so in reality I'm getting time reset to 00:00 UTC. After a few seconds, after unit tunes to GPS, widget shows correct time. If I turn off the GPS time sync, the time never gets set.

3. Prove that a software reboot causes time reset too:

Have ignition on all the time. Make sure head unit works and has the correct time. Use any software that can reboot the device. I personally use Xposed Installer application, it has a reboot function under Xposed Framework section in it. So go to apps, Xposed installer, Framework, choose Full reboot option and confirm "OK". Unit goes to reboot. After boot, the time is 03:00 again for a few seconds until gets synchronized with GPS.

I hope all I wrote above clearly indicates that the issue is not related to power loss by the device, but rather to the boot process as such.

Or, may be my unit has somehow broken realtime clock circuit, where the time should be kept while Android is shut down.

Or, may be there is some issue with MCU firmware/Android part, causing Android cannot get the time from hardware RTC circuit during boot.

So I completely lost on what I may try to do, and also I'm curious, am I the only one with this issue?

PS. I have a JY unit, RK3188, 1024x600, stock MCU 2.73, Android part from Malaysk dated 13-Aug-2015.

It seems like there are so many combinations of head units/cars/connections that you can feel like you are on an island sometimes with these things. Guess that's what we get for buying Chinese units at 1/3 the price of big brand names...

I'd love for someone to tell me what the dimming switch on my dash is supposed to do to the head unit. Mine does nothing!

Wipe after upgrade

I just upgraded my 3188 1024x600 to Malaysks latestfirmware (it had the previous Malaysk firmware on it). It identified the update files on the SD and asked if I wanted to upgrade, so I said yes. It installed the upgrade, rebooted, said it optimised the apps. Then the start continued and I saw the home screen with all the apps intact...

... for exactly 2 seconds, then it said "Shutting down" and a little logo with the green android man appeared saying "Erasing" and BAM there I was with a factory reset unit.

So I spend the last hour reinstalling and configuring everything. That´s a monumental pain in the ass. What did I do wrong???

Is there any way to change the daydream for the screensaver in Malaysk's ROMs?
[MTCB Android Head Units Q&A] KeiserSozeyFr:
Same issue with my head unit (crash + mic problem).

I use Malaysk's ROM, one from July, I don't remember exactly witch one exactly. RK3066 800*480.

But it happens only sometimes.

Are you on the last updated ROM ? maybe something was fixed on newer versions ?

I don't think it's a defect from the head unit. Previously, I used a stock Android 4.2 ROM and it never crashed.

Today I installed the apk version 3.6.16, I will see if issue happened again. But unfortunately, this version does not support the "OK Google" detection from any app. At least, with my language (French)

fabien_m2002, I am currently rewriting my app CarService to add some cool features. One of them is to be able to start/answer phone call from "normal" dialer application, like Ex Dialer and Google Now by vocal command.

Currently, it is working well with ExDialer but with Google Voice command, it works only sometimes. Maybe it is linked to the crash/mic problem because it works very well with another Android device.

When my app will be ready, I plan to put it on Play Store with a cheap price and a free trial period.

Hello,

what's difference between NEXT_LAUNCHER and the other one?
[MTCB Android Head Units Q&A] Telemachus:
Next_launcher has a custom launcher built into it, while the other has the look of the stock firmware's launcher.

With either one, you can add your own launcher. NEXT is too cumbersome for me (how do you remove a blasted widget??) so I stick with the stock.

[MTCB Android Head Units Q&A] KeiserSozeyFr:
No, my unit is a KGL

I seen you tried many solutions including changing ROM. Did you try to flash a ROM then install only Google without any other apps and try using it ? To see if the issue is due to an incompatibility with an other app ?

When it rebooted it said optimising 1 of 42 apps.....went through them all, rebooted again and blank install

None of my apps, no saved settings, nothing.

Just a word of warning for others

seems so

Finally got the car recorder to work - is there a way that I can set it to start recording right after boot?

Apparently all we need to make sure in terms of camera specs is that it's UVC. Was hesitant to purchase a Logitech / Microsoft webcam knowing that I can only record 640x480, so went ahead and bought this one:

http://www.ebay.ph/itm/Hot-Silver-U...r-PC-Laptop-/121717326033?hash=item1c56eb00d1

Works like a charm. My only issue is I can't use any other recording app... getting a "Cannot find storage card" on either Caroo or DailyRoads Voyage.. verified via SDFix that apps should have access to my SD cards, but still doesn't seem to do the trick for me.

Hi guys,

Sorry for my bad english.

I read a lot of this thread and not all is clear to me.

I read about MCU and firmware, the MCU, my MCU is KLD (Klyde).

[MTCB Android Head Units Q&A] dhmsjs:
I don't know what it does in your car, but in mine (2001 Toyota 4 Runner) the dimmer circuit does not connect to the head unit at all. There is only the "illumination" wire going to the head unit. That gets +12 volts when the headlights (or running lights) are on.

The dimmer knob on my car connects to the NEGATIVE side of all of the dashboard lights. When turned to the brightest position, it brings the negative side of all those lights to ground, so they get the full 12 volts across them. When you turn the knob down to dim the lights, it raises that negative side of the lights about 1 or 2 volts, causing the dashboard lights to dim.

I also installed some accessory pushbutton switches that have LED lights behind them, and connected those to the dimmer circuit (instead of ground) thinking that they might dim too. Unfortunately the LED lights use far less power than the old incandescent lights, so they don't dim noticeably.

Bottom line: I would not expect your dimmer knob to ever change anything on the head unit. I hope that helps!

Hello again,

I write before with my problem.

I use Erisin ES2007a with stock Android 4.4.4 with RK3188 Quad-Core 1024x600. I drive Chevrolet Lacetti and I want use original steering wheel controls, but I can't. I connect Cables for SW (key1 key2 and GND) from Head Unit to my Steering wheel wires (on my controls have two wires and I connect it to KEY1 and KEY2).

And nothing happened... In Settings - Steering wheel controls I can't program my steering wheel keys to control Head Unit.

My car Chevrolet Lacetti don't have CAN-BUS, steering wheel controls are RESISTIVE TYPE.

What I do wrong to don't have steering wheel control on my Head Unit?

Maybe if I root my Android 4.4.4 with [MENTION=3590033]Malaysk[/MENTION] ROM's it fixed... or I don't know.

Please help me with this issue because it's important to me to use my original stuff in my car! :(

Hi all,

I recently purchased an Eonon GA5164F and its absolutely awesome apart from the wifi strength being terrible. I am thinking I want to install a rooted rom on it though. So its as simple as downloading the correct MCU and ROM onto an SD Card and doing the update?

I'm just wondering what the best way to backup everything that is currently on there since I don't have root or access to a laptop. Can I backup everything to an SD Card somehow?
[MTCB Android Head Units Q&A] acun:

[MTCB Android Head Units Q&A] grahamwright1:
I think you can backup your App's using the Settings, Backup & Reset option to backup to an SD device. You might want to try the backup, and then check the contents of the SD card to see what has been stored on the card....

I downloaded Titanium Pro and used that the backup my JY unit.

[MENTION=6870626]marty_s13[/MENTION] if you just want root, try this: http://xdaforums.com/showpost.php?p=62047649&postcount=16547

It's actually permanent, you can ignore the "need to install Superuser or SuperSU" part. :)

Otherwise, you are correct in that you can install a pre-rooted ROM. The ROM does NOT have to be specific to your head unit. You can also update your MCU as well and that DOES need to be specific to your unit.
[MTCB Android Head Units Q&A] grahamwright1:

Hello Malaysk. I just installed your latest firmware released 6 is September. As always I must congratulate you, you do not disappoint never.

Clear passage to point out some issues that I have:

1-You always insist on doing a reset of the internal memory after installing the firmware. In this version I have seen that at the end of the installation, in mode recovery still appears labeled "Erasing" that it is he who appears when reset after flashing. The question is whether that step is no longer necessary.

2-I thought I read in the Forum that from the penultimate version of its firmware new firmware can be installed without losing the personal applications installed. Could you explain if and how it is done. I have attached Recovery.jpg capture.

3-Lowering the top bar have found the SPEED icon, can you tell me what it is. I pressed it once and turned off the screen, you have disconnected the WiFi, and I think that also the BT. Deputy capture SPEED.jpg. I correct: I just realize that this is the airplane mode, the label has confused to me, and not I've noticed the icon.

4-ON/OFF icon appears on the right side of the screen. I have seen on their YouTube video that when pressed allows resetting the unit, even in Recovery mode. Well, in my unit the only thing that happens is that the screen will be black, though the music is still playing. It could clarify this. Deputy capture On-off.PNG.

5-Deputy also capture the information of my unit.

I put this post in the Forum but I also attached a copy by private message.

1. It is necessary when you go from a standard rom only. It is because of the different partition layout.
