Well, not like my PowerAmp widget is starting quickly anyway. lol Are either of those services you mentioned Xposed modules in the Xposed library or do I need to direct download somewhere?

Also, will they conflict in any way with XposedMTC? I finally have that running my dimming just perfectly. lol
[MTCB Android Head Units Q&A] agentdr8:
Both are just standard apps. And depending on what keycodes your forward/back keys send, it's possible that XposedMTC will also send the same commands for Poweramp, PlayerPro, and standard media commands (depending on what music player you have set in your prefs). This could result in double key presses.
[MTCB Android Head Units Q&A] ultradj83:
Dear,

I've been running this ROM for several days, everything's perfect but 3G.

I've been testing it on the same device as you, with a tenth of dongles.

It works better than on other ROMs, but it's sometimes still getting stuck.

I can't understand if this is caused by the particular power management inn this devices or just by the 3G subsystem in the kernel that sucks, or ever by poor power supply in device's USB ports.

First of all it's difficult to stream video via 3G, sometimes it just fails to buffer, sometimes connection gets stuck and it's necessary to disconnect and reconnect the dongle to make connection with again.

Also, it fails in managing the dongle when there's no coverage.

Just to be more clear, here's what happened on yesterday:

1. Video streaming attempted with AllMyTV app, didn't work.

2. Entered a garage with no coverage.

3. Car stopped.

4. After 15 minutes, car started.

5. Left garage.

6. 3G failure, signal icon not showed in the notification bar.

7. Dongle disconnected and reconnected, 3G signal showed, no connection.

8. Car stopped.

9. After 2 hours, car started.

10. 3G signal showed, no connection.

11. Dongle disconnected and reconnected, 3G signal showed, connection ok.

Really frustrating...

Are you experiencing the same difficulties?

What 3G dongle are you using?

Thanks a lot!

Agree with pakidermo5000 and thanks to him for putting me onto this unit. My friend also has the 8 inch unit and it is indeed beautiful.

HuiFei - 2 DIN Pure Android 4.2.2 A9 Dual Core Car Stereo Radio Head Unit

Is the boot time until anything works? Or for example, audio will start immediately from where it was left off, but the system is only accessible after 24 seconds?

I scanned the other unit threads, but read this one completely.

Does anyone know if there is a universal unit with no DVD, just a screen and sd slots?
[MTCB Android Head Units Q&A] pakidermo5000:
It should be easy, we just need to find out which is the part of the circuit for the delayed shut down and increase the resistor that governs it. It will increase the standby time... Maybe we could ask Keylo. Then, it is just a matter of replacing the resistor.
[MTCB Android Head Units Q&A] Varghjarta:
Long time thread-lurker here and soon to be buyer, liking a lot of what I read here :)

Worst case scenario we could hook the radio up to the constant 12+DC, but have a relay between them controlled by an arduino that upon power from the ignition pin shorts the relay, powering both itself and the radio from it, then upon no ignition counts down letting android shut down and then opens the relay in affect also cutting the circuit for itself and should thus not drain power while not in use.

This of course also allowing us to decide fully for how long the radio stays on when ignition is off (enough for picking up a pizza etc).. Or is this extreme overkill and/or stupid? :) -- I'm just saying because I already have a nexus 7 for carputer and an arduino to control it and an amp's power supply.
[MTCB Android Head Units Q&A] sciallo:
I also follow multiple threads, AN-21 U most as that's the unit I have.

While you can certaintly try to come up with a hardware solution, use arduino, IOIO or delay relays etc. This is something that could definitely be adressed by MCU software as it happened with the AN-21 U. At some point an update (both MCU and system) gave us a new option in the settings for shutdown delay. The screen goes off, music stops, amps go off etc. but for a menu defined amount of time, the systems stais on with network connection as well (great for sinking files from my wifi).

As it stands, you do have a very short shut down delay, when you cut off the acc power your unit performs a clean shutdown. this is controlled by MCU, as long as you keep getting enough V. on the permanent + wire (in some cases cranking the engine drops voltage causing improper reboot and possible file corruption with some units/cars - new battery, capacitor or secondary battery in a UPS type configuration would be the only solution there). Ideally the manufacturer could come up with a standby mode, shouldn't be too hard for them and would make this unit that much better...

Having this option on my unit also allows me to try something else too, that's in the plans:

I have interior and running boards lights that come on temporarily when I unlock my car with my alarm remote. using a couple of diodes to isolate the two voltage feeds, I plan on feeding the ACC wire with both ACC from the ignition key as it is already AND the interior lights. I experimented with this, a temporary 12v on the ACC wire is enough to start boot, at this point the shutdown timer keeps the unit booting and on for the set time. It will start the boot process as I'm walking to my car :)

[MTCB Android Head Units Q&A] nexgen10:
I have a little update on this unit I wanted to share.

The other day, I came out to my car and started driving. It was hot in my car, and to my horror, the radio did not power on! I pressed the power button, turned the car off and on several times, checked the fuses, even removed the unit from the dash and pulled all power to it. I still could not get it to power on. I feared I had lost the unit.

A few miles down the road, and all of a sudden the unit powered on and came to life. Turns out, there is a thermal shutdown circuit. If the temperature is too high, the unit will not start. I have no idea what the magic temperature is for this thermal shutoff, but it does exist.

Temperatures in a car can easily reach 140 degrees in the summer time.

http://caninecollegemi.com/1758/pets-in-vehicles/temperature-inside-car-chart-2/

This particular day, it was in the high 80's and my car was sitting in the direct sun for about 8 hours. I did not have a windshield reflector and all the windows were up. My car has a dark interior.

I dont think this is a problem with the unit, and I imagine most in-car PC's and tablets would have this same issue.

[MTCB Android Head Units Q&A] pakidermo5000:
During the boot up process nothing "works" except rear view camera when you are in rear gear mode.

When the unit is booted, all the apps that were left open when shutting down, will start automatically and resume. Music will resume where it was stopped, (at least poweramp).

[MTCB Android Head Units Q&A] pakidermo5000:
THNX THNX THNX A LOT !!! You are the master!

I finally installed xposed framework and app settings modules, and gesture module. (I had to sideload them with adb as the unit refuses to install them).

It rocks !! No need for 800x1080 anymore as you can tweak the individual apps that do not fit in the screen. I reduced the dpi of spotify and now is much more usable, also chrome, and some other apps. I love it

I also set a gesture to go "home" and for some other stuff, and now the whole unit is much better as I do not need to touch carefully on the upper left or right of the screen, just swiping does it.

I have been trying to set Loud automatically at boot, but could not figure out how to trigger the Amplifier menu with Tasker (did not try automagic yet). Can it be done via a shell command? Anyway, I will just wait for your file.
[MTCB Android Head Units Q&A] typos1:
Really ? Those temps would be easily achieved in the UK inside a car in summer, so not that hot at all really !

I can probably live with that,although by 30 seconds you're driving already - and fiddling isn't exactly ideal.

You don't need to do anything, everything just boots up and starts automatically. I find 30s a bit too much but bearable, 15 would be ideal...

If you like I will upload the decomplate apk in zip file.

Which FM tuner chip do you have? I have TEF6606/TEF6624. I don't have to use AF function, I traffic only in local. I try the AF function in the near future.
[MTCB Android Head Units Q&A] marco.lav:
Thank you so much for your interest;)

my chip is the TEF 6624

I know java, but in my life I do not do it sviluppatore.Le my knowledge have not evolved.

the radio that I would change is that of version 4.4.4

The problem of AF works I think is linked to poor management of the stadium in amplifying, and a setting of the chip.

The chip has two receivers, one for listening to the radio, and the other to find the alternative frequency, but also it is managed badly, favoring the least time to mute.

http://www.ndatasheet.com/datasheet/TEF6624/785425/1

from this link you can download the datasheet o tef6624.

on page 13, there are three ways to operate the af.

the second way rather have a shorter time mute.

but not always find the station we were listening to previously.

or we tell the chip that must find the previous station, even with long time mute. or rewrite from scratch AF.

as you can see, has two demodulators, one for listening to the radio, and the other to search for alternative radio. see timing diagrams.

if I send the decoded file, I'm glad,

and even if you give me a hand;);))) I do not know if I can do alone, perhaps together we will succeed

[MTCB Android Head Units Q&A] ultradj83:
Boss, I'm not sure I'm getting your meaning.

You mean to flash a firmware into the modem?

I'm pretty sure the cause of the connection problem is software because it changes changing unit's firmware.

One more problem is that, when connection works, it get frozen playing video streaming or doing a speed test, this might be a power problem that makes the dongle frozen when heavily loaded...

Btw try Malaisk's roms, they're fast and stable.

3G KitKat

Its not the dongle, the 3G connection thing is missing in the top tray.

Ive tried all kitkat firmwares. And during the last test, the official one, I found that this is related because of timing on the USB harddrive.

Can you give me the links to Malaisk`s roms?

Thanks

If they both start up at the same time, then the harddrive mostly wins, if the dongle wins then the harddrive is missing.

This worked fine for 6 months on 4.2.2, Now on any 4.4.x I have this issue.

The work around is to poweron the drive a few seconds after boot, which is fine for me, just need to make a delayed relay.

I don't use the USB drive much anyway. For specification, it does not matter if one is on a hub or not.

The hub and harddrive are powered externally.

Ps if you upgrade while you`re radio is still on, it will continue during the flash, something I would not recommend if you are upgrading the MCU also.

Any idea what the deal is with 4.4.4 and why it doesn't mount external storage the same way as 4.2.2?
