[MTCB Android Head Units Q&A] nzdreamer55:
Thanks. So I figured out the the Xposed installer and XMTC was being installed on the SD card. I went into my apps and clicked on the move to machine. From there I restarted and now I am able to get the screen to dim when a specific time is reached. I cannot get the screen to brighten back when the end time is reached. I also need a little more hand holding to make sure that I am doing things correctly. If I knew that I had it set up correctly then I could play with it and figure out these issues, but I am hoping you can tell me what SHOULD happen.

1) Does the XMTC service need to be running for the dimming function to work or is it for the automatic time settings to work?

2) If the service is running and the "set start/end times automatically switch is OFF will the dimming trigger on the times I put into the start/end or will it use times that are automatically generated?

3) Does the service need to start when the radiohead starts or is this only if it is using the automatic start and end time calculation?

4) What does the screen filter function do (is it active on 4.2.2)?

5) When I make changes to the settings within XMTC do I need to reboot the radio? reboot the application? Restart the service?

6) Is the start and end time the range when dimming is activated or when dimming is not activated?

Lastly, I have attached a log screen shot showing that the time is past when I had scheduled the dimming to stop but XMTC thinks that it is outside of the range. I'm a little closer and maybe with some of these questions answered I can figure it out.

Thanks for this neat little program

I use a Genius MIC-01C with my KLD head unit over the stock external mic jack plug. I didn't solder anything, sound quality is good (my callers said).
[MTCB Android Head Units Q&A] agentdr8:
Is this when pressing your MODE button on your steering wheel controls? If so, you may need to remove some of the sources from the mode switch selection in XMTC preferences.

Nope, that's only for updating the automatic dimming times.

If the service is running, and the current time is not within the dimming period, it will override the start/end times you've specific with ones generated from the algorithm. That shouldn't be the case, but I just checked and I guess I never put in a check for that, so thanks for bringing it to my attention. I'll fix it for future releases so the service can't update the times unless that switch is enabled.

Nope, only for auto-updating the times.

Some people were unhappy with the backlight brightness, even when fully dimmed. If you have the Screen Filter module installed (and configured), XposedMTC can activate the filter in addition to lowering the brightness. It can make the screen very, very dim, or even change the overlayed color (i.e. lux, Twilight, etc) during the dimming period. On my GS, I have my backlight set to 1, and my Screen Filter setting transparency to around 145. Makes for a nice experience when it's dark outside.

Depends on what you change. For the most part, the settings are reloaded when certain hooked methods are called. But other settings like Debug require a reboot.

Start time is when the dimming period should start. This should probably always be a "pm" time. Conversely, the end time is when the dimming period should be over, and that should most likely be an "am" time, after midnight. Basically sunset and sunrise, or something of that nature.

What was your start and end times?

The Ownice and Newsmy seem like good units, I ve read both threads. But they have their drawbacks, the Newsmy does not have RDS enabled yet and only has 2 RCA outs.

The Ownice doesnt even have root yet (although havent read the thread for a couple of weeks they may have now) and no one seemed that bothered when I suggested ways of trying.

Both have MCUs that are very immature compared to the units in this thread (and these frankly are still a bit immature, theres still lots of cars where all CAN Bus vehicle functions arent working)

Having read the threads on all 3 units and now knowing that quadcore version of the units in this thread are imminent (and will be pretty much the same apart from the upgraded processor and RAM), I would wait and get a quadcore HuiFei type unit.

As the quadcore units will be the same apart from the upgrades, all the external development we ve done and all info we ve gained we ve in the last year+ of this thread wont be wasted and most will apply to the newer units so people can upgrade and still read/contribute to this thread.

Then, more than ever we would need a proper "RockChip Car Stereo" section, with sub forums for MCU stuff, dual core stuff, quad core stuff and a general section for both units.

Do you have a dash light dimmer in your car.....when i first put my headlights on, the screen dimmed and the hard buttons illuminated but then started flashing / stuttering.

I realised my dash dimmer was set to half way which doesn't give full power to the units lights. I thought the unit had a fault but hen dialed it up to full and its ok.

Perhaps at very low you might not get hard lights at all?

What version of the module are you using?
[MTCB Android Head Units Q&A] clearchris:
Arduino Reboot Control and SSV

Ok, my parts have arrived and I have sketched up a basic design. I need to ponder this a bit more, but here's my first cut at this.

Speed sensitive volume line 0v to 12v+ -> voltage divder to 5v+ -> arduino analog input

ACC 12v+ -> voltage divider to 5v+ -> arduino digital input

arduino digital output -> relay switch battery to ACC input on radio

arduino analog (pwm) output -> voltage smoothing circuit -> key1 or key2 on radio (button press emulation)

real time clock module for scheduling

Right now I'm just going to hook up the arduino to 12v for power, longer term, I need to put a buck step down converter in there and bypass the linear converter to save power.

This would allow me to:

1) Raise and lower the volume based on speed by emulating keypresses to the radio

2) Put the radio into standby mode by emulating a power down keypress to the radio. Concurrently, ACC can be held high to prevent a cold shutdown.

3) Turn the radio off cold by stopping power to the ACC line on the radio.

4) Wake up the radio based on the real time clock module by switching ACC (think booting up the unit at 6am)

5) Detect if the car has not been started in a day (or set time period) and go into "vacation mode" (power down radio until next ignition)

Can anyone else think of any other use cases here?

MCU updating

Hi,

I have KLD unit.

Can I update the MCU only without updating the OS?

If possible, what is the procedure?

Thanks
[MTCB Android Head Units Q&A] -=Gerner=-:
Yes, it is.

Update procedure: You can find all information, at first page.
[MTCB Android Head Units Q&A] typos1:
Yeah, I remember you saying, hopefully that will be the solution for my Klyde, but my JY has 2 rear ports only neither of which work. Someone suggested a few days ago it maybe a memory/cache issue.
[MTCB Android Head Units Q&A] nzdreamer55:
Thanks for all the info. I have set it up so that it will change automatically, however it only will dim the screen now. I have to stop the module if I want to change the screen because as soon as I adjust it back to bright, the module will darken it to the dim setting. Such a cool module, but it won't play well with me :(

Any other ideas?
[MTCB Android Head Units Q&A] agentdr8:
It thinks it's within the dimming period, so it will always override your brightness settings. Also, there's another slider to adjust the brightness level when it isn't in a dimming period. Allows for adjusting brightness in both situations (day and night).

[MTCB Android Head Units Q&A] agentdr8:
It's possible that if you have the non-dimming brightness slider at 10 that it is no different than 0, which is why it doesn't appear to do anything. The backlight usually accepts integer values between 0 and 255, but on some headunits (like my GS and KGL), any value under 10 is the same as 10, which would be the lowest brightness it can go. Try changing the non-dimming slider to something >100.

If that doesn't help, try enabling Debug in the prefs and reboot. Then post up the Xposed Installer debug.log.

Which system apps are safe/unsafe to uninstall

Hi folks.

I have a HuiFei 4.2.2 unit that works pretty well, but i'm running out of space and i suspect some of the pre-installed system apps are eating up cpu resources.

I'd like to uninstall some of the system apps. I know you can't uninstall them normally but my device is rooted and there are 3rd party tools designed to uninstall system apps (gmail, adobe reader, etc.); for example: https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp

HOWEVER, I have not succeeded in making a backup of my unit, and i'm very scared of bricking it by uninstalling some system process that the system requires.

Does anyone have any insight into which system (built-in) apps on these units can be safely uninstalled (by a program like this)?

Thanks in advance!
[MTCB Android Head Units Q&A] Ninonuk:
Now and it works!

Also, I have new insights. My problem has nothing to do with the ROM of Malaysk! I have this recovery unconsciously by the program "Arctools" installed on the radio. I still do not know how I get back the normal recovery back.

So, I can now select with the mouse everything in this recovery. However, this recovery requires a "update.zip" and that is exactly my problem. What needs to be in the update.zip there that I again get the normal recovery back?

Can I somehow import the recovery in normal operation?
[MTCB Android Head Units Q&A] agentdr8:
You can flash the stock recovery image from a running system. See if the rom includes flash_image.

Problem with HU of my fiend

My friend has following issue:

The GPS time update is on. After 30 minutes run the HU is freezing. The radio screen is disappear. And the HU shows the attached screen.

The second issue: the HU is freezing, the HU shows the radio screen, the HU doesn't response the pressing of the buttons and touching of the screen, but the music of the radio is listening fine. After the radio music was stop. The screen stands after ignition off for 2 minutes.

If the GPS time update is off, the issue repeat after - later - approx 50 min. after start of HU.

My friends tried the android upgrade, but the problem is yet.

How can we resolve this problem.

You have two ways

1. Install prerooted image and just copy other launcher to the apps folder with proper access rights and rename or move old one.

[MTCB Android Head Units Q&A] clearchris:
What are the problems? I have noticed the colors aren't correct, but that's because there are green, blue and red LEDs. So if you choose "yellow" you don't get yellow, you get green.
[MTCB Android Head Units Q&A] -=Gerner=-:
Yes, That is the problem with the v2.40.
[MTCB Android Head Units Q&A] clearchris:
Well, an MCU update can't fix that. The only thing that can fix that is to solder in different LEDs, or for the software to be honest about what the hardware can provide.

The first probably isn't worth the effort, and the second is unlikely considering the trickery of the new 9 slider eq that averages down to 3 sliders in hardware.

What has the simulated 9 bands on the equaliser got to do with the RGBs ?
[MTCB Android Head Units Q&A] clearchris:
To me, the "simulated 9 bands" (generous verbiage, btw) implies that someone is untrustworthy and casts their other claims into doubt.

There may be a perfectly rational explanation for the "simulated 9 bands" but it sure seems sketchy on the face of it.

I don't know why the sales claims of many imported products are inflated. These units in particular provide amazing value, there's no need for it.

Anyway, I think we all know these units are "caveat emptor", so I'll refrain from further discussion along these lines. Thx!
