Question RE powering the usb ports.

I have purchased one of THESE and I will be doing the mod to power the USB ports but what power source do you recommend?

I run the USB dash cam and a 3G USB dongle so would a switched power source be better or a permanent power source? (not sure if these devices would unmount or drain the battery by staying on)

Also I did try an external power source using one of THESE and ran into a problem I used one of THESE to power it on a switched live just to test it but ran into a power surge issue, My car has a feature where if there is any sort of surge it shunts excess power to the windscreen wipers (they turn on) so is it ok after hooking up the above module to cut the tracer on the PCB that usually provides the power? that way there should be no back surge.

Any help or advice would be appreciated.

Thanks

I'm not asking when, but WILL you be taking the stock ROM and modifying it? (RK3066 1024x600)

If so, i'll wait for the update before i take a chance at doing too much damage to modifying ROM myself and adding root (amoungst other mods) :)
[MTCB Android Head Units Q&A] vdubskey:
I have a Hot Audio Unit. I chose the JY launcher version of Malaysk rom because it is the same UI as my unit. But I flashed the right version for my unit RK3188 1024x600. I have the most updated stock firmware from the manufacture and the problem persist. I also tried MCU 2.60, 2.67, and 2.70 and no go. It looks like to me the internals are being tripped like there is a spike in voltage but I have had my meter my regulated power supply the whole time and its getting a stable 12V 30A. Ive brought the voltage all the way to 9V and high as 13V and same thing. My other theory was a thermal sensor was being tripped. Shame because its brand new. Is there a way to flash the firmware using my computer and the rockchip batch tool that is used on the newsmy units?
[MTCB Android Head Units Q&A] Malaysk:
Yes, of course I will be firmware on for RK3066 1024X600.

I wasn't sure if the RK3066 was going to be updated for resolutions of 1024x600.

I see a lot of talk about quad core units and a focus on 800x600 units.

Didn't know if we were slowly abandoning work on dual core and 1024x600 units.

I'll wait patiently for your update. Quite happy with the current firmware, but also looking forward to the ability to update firmware without wiping :D

[MENTION=3590033]Malaysk[/MENTION] I'm eager to try your rom now I have fixed some writing issues :)

I have a question about the 2GB storage, where do you get the extra GB from? Is that from the NAND flash? And would it be possible to make that 3 or 4GB? And can I do that myself? I really want to prevent having to move apps to the SD card...

Also you say in your update instructions that I will need to wipe the SD card. Why is that necessary?
[MTCB Android Head Units Q&A] Malaysk:
If you are not afraid to test the new firmware :D (I have no way to test with a resolution 1024X600) you can check here (with the regular launcher) and then write eat bugs?

No can bus. Yes the Ignition wire is also receiving 12v. I am using a 12V 30A regulated power supply. I also tried my automotive power supply the DCDC-USB and monitored the voltage via the pc and usb cable and everything is fine there. I'm not sure inside the car would be any different, if anything the fluctuating current from engine cranks and spikes would only make it harder to track the issue. I spoke with Hot Audio and they said they will ship me a new unit but I have to ship this one back, to china. I wish I could just fix what I got instead of having to wait another 2 weeks. Bummer. I posted a video of whats happening at https://youtu.be/CZCH-6rVwEI
[MTCB Android Head Units Q&A] Blaze Falconburger:
Graceful shutdown - how can I test or confirm the unit is gracefully shutting down? It displays "Shutting Down" for a few seconds (or Power Off, I forget the exact words) when turning off the ignition. If I turn ignition back on after a short time it resumes rather than a full boot, and if left over night the next morning it does a full boot. So I think from this I can conclude it doe shutdown gracefully?

The reason for my question - PowreAmp does not resume the last played position of the track. It correctly remembers the last track (this is written to the file on track change), but the last play position is not updated frequently, only when the service shuts down.

It used to work perfectly with an older ROM (original, from ~6 months ago), but I can't get it to work with Malaysk's last few ROMs, but admittedly I never updated PA so that could also have changed (though change logs did not indicate anything obvious that would affect this).

I also tried using Folder Player, and this exhibits exactly the same condition. However if I quit each player cleanly and reload without rebooting, they will resume from exactly the correct position.

Can anyone help, it's driving me nuts! Thanks
[MTCB Android Head Units Q&A] swanie2000:
Not sure if you figured this out yet or not, but I believe you hooked your amp up to the antenna wire on the back of the head unit. The Antenna wire only has 12V on it when the radio app is open. There is another wire, for the remote amp turn on. I seem to remember them both being blue, but one of them had a stripe on it. Sorry I can't remember exactly the colors, it's been nearly a year since I installed my HU.

Hope this helps!
[MTCB Android Head Units Q&A] vdubskey:
Well I said **** it and went and hooked the unit up in the vehicle, figured I would try your advice dsa8310 before I shipped it back. And same results. But this time I had to hold the reset button to even get it to try and boot after I turned the ignition on, and about 15 seconds later it died. Didn't even make it to the OS. And the front panel lights blinked slowly for a couple second during initial power on. Strange.
[MTCB Android Head Units Q&A] agentdr8:
That's from Car Service. You can disable that in the app settings (have it not start on boot).

If your bench power supply is solid, then it's likely a bad unit. The only thing I can think of would be to check the fuse(s) on the ignition and batt lines to make sure they're not defective.

[MTCB Android Head Units Q&A] vdubskey:
Well if you can take your unit out of the dash for a second you can listen or watch the rear fan turn off. That is when the unit is actually powered down. Change the power off time to 30 seconds for this test so you don't have to wait for ever to confirm. Are you using a usb drive for your music when this occurs? I ask because I had this same problem with my Nexus 7 in dash and it happened because android can not mount the USB drive fast enough or the 5v usb port rail was being shut down before the OS fully shutdown. I fixed it by hooking up a powered usb hub. Not sure if that's what is going on here. I know I have seen a lot of discussion about keeping the poweramp service live with that runtime script "install-recovery.sh" or doing it through pcvbuilder.

---------- Post added at 06:03 PM ---------- Previous post was at 05:54 PM ----------

Yea I checked the fuse on the back of the unit and its not blown. I will try and replace it and see. I also tried different power supplies and at different voltages so I doubt that's the problem, otherwise I wouldn't get the inconsistency of variable runtimes. Sometimes it doesn't make it through boot. Other times it will run for 20-30 minutes. When I shot that video for the manufacture I was getting frustrated cause it wasn't showing the problem when I was taping. I taped for 45 minutes before it happened. Well I just boxed it back up and going to return it. I wonder if the upgraded RK3188 has something to do with it? Because on the motherboard it says RK3066 MB-v3. But from what I read on the WIKI, it should have no ill effect and they are compatible as long as I use the factory MCU. Oh well, I have a Newsmy N3001 to play with while I wait for a new Hot Audio unit :D

Only with Car Service I'm able to control Spotify correctly. I just installed [MENTION=3590033]Malaysk[/MENTION] 's rom so will double check that.

I really like the Malaysk's rom (RK3188 1024x600 4.4.4 August-latest with JY launcher) so far, feels more stable, great work!!! Still not sure what the best DPI would be, I'm missing the two panel settings screen for instance (I have the Quad 1024x600 model), but that's just a matter of taste I guess.

Some other feedback so far: Had to install the xposed framework myself, not really a problem. The Malaysk app that controls the power button and screen off button didn't do much, could be because of xposed not fully installed yet. I'll check that later. Wifi seems to work much better (easier in connecting).

I'll let you know when I find anything else :)

That's typical of custom roms that include the Xposed framework. Better to let people decide if and when they want the framework active.

Sorry, didn't realize that power icon wasn't part of Car Service's UI. Never seen it before; does it only show up when Car Service is in the foreground, or does it just pop up whenever?

hi,

Is there a possibility to update Ford SYNC app added to my aftermarket RK3188 Android HU? I've got one it in my Ford Focus to use with speech commands to communicate with my phone, read incoming SMS or controll USB audio but the layout of the apps is awfull and it's hard to use therefore. In my opinion that's the clone or emulation of the original because FORD SYNC is implemented, I think, in stock audio unit, correct?

And once more,

my Ford has also a special equipment as " semiautomatic parallel parking" Now when I've fitted the unit there is nothing on the screen when I push the button for SAPP when I want to park and use this special feature.

No sound, no commands on display etc. It's annoying

Clima controls do display on the bottom of the screen

In factory settings in menu "canbus" I was told to select "Focus raise" among a few additional Ford models.

Is my "problem" to resolve?

Spotify Saved songs

Hi all,

Question for people using the Spotify app. The app runs fine, but when I download music to the unit, it will only stay downloaded for the time the unit is on. After the unit goes through a complete shutdown process and restarted, it says I have no music downloaded.

I have tried erasing/formatting multiple SD Cards and only having one card in at a time (either only the GPS SD Card or the regular SD Card slot).

Additionally, when the unit starts up it will briefly post a message that no SD Cards are present and then disappear as the SD Cards mount.

Any thoughts on what might be causing these issues?

RK3188 1024*600 - Malaysk 4.4.4 (August 13 version) ROM with JY Launcher, KLD2 v2.67 (Stock), have tried 8gb SD Card (Sandisk), 32gb SD Card (Sandisk), 32gb SD Card (Samsung).

**SOLVED**

I think I figured out why it was doing this. I was using the PCVStartupBuilder app to reboot my unit when I needed to do a complete restart to check something while the car was still on. Sorry for the confusion!

Malaysk app worked after enabling xposed.

It's on top of any app, just used that app for a clear white background. It's exactly every 30 seconds, so that cleared any loose wiring.

[MTCB Android Head Units Q&A] Tha_Stig:
To root you can go to factory settings and type in *#hct#root# (I am not 100% sure if this works because I have not personally tried it yet)

Otherwise, all Malaysk ROMs come rooted.

To install his ROM:

1) download the ROM from the server

2) install the update.img file onto an SD Card (must be in the main directory, NOT in a folder)

3) insert SD card and you should be prompted to update the firmware

4) After install is complete you should have the Malaysk ROM

NOTES:

- You can't backup your stock ROM to my knowledge, but all stock images are on the server or on the google drive link that is floating around this thread so don't worry about it.

- READ MALAYSK's ROM POST BEFORE DOING ANYTHING!
