I see.. that is a great mod
[MENTION=3590033]Malaysk[/MENTION]

would you please include these in the next rom release?

---------- Post added at 03:18 PM ---------- Previous post was at 03:16 PM ----------

you have a very limitted space on the nand

custom roms give you the max you can get

they can not magically make it bigger

use your sd for your music.. the headunit is a limmitted device it will not wash and iron your clothing for you as well as being a radio
[MTCB Android Head Units Q&A] markcm:
Can you please explain your comment?

I am not having an issue with traditional Music files, all of my traditioanal .MP3 music files are on my external SD and that is working well. My problem is with my two Music App's, Slacker RAdio and Amazon Prime Music which have an option to "download content for offline playback". These download files are not standard .MP3 files, they are encrypted for the specific app to prevent piracy.

My HU has 16GB on the SOM, 12GB of which is currently partitioned as "internal SD" and has nothing on it. 12GB is more than enough for caching the files for offline music. My problem is that my Music apps are placing their offline music cache files on the 2GB Internal partition, not the 12GB Internal SD and I cannot figure out how to move them because the Music app is pointed to look at the Internal /Data, not the Internal SD.
[MTCB Android Head Units Q&A] pk313:
Same problem with napster now....and any wipe all my downloaded music is erased...with no way to save in an other folder ...only internal sd

[MTCB Android Head Units Q&A] doctorman:
I think there was a setting or an app that would move the amazon data to sd card.

when I used to use amazon music there was hackerware that would let me save the downloaded offline music and organize them infolders on my ext sd card .. not sure what the app was as it was a long time ago.

but I see you have 16gb which is double most HUs not sure if there is an asy way to change partition for 16gb so you have more room in data vs internal sd... malaysk or DSA should be able to help with that
[MTCB Android Head Units Q&A] markcm:
The issue with "moving to SD" that I have encountered with multple apps including both Amazon Prime Music and Slacker is that only the App is moved (about 15Mb), all of the DATA remains on the Internal partition under /Data.

Correct, there is an app on Google Play that will let you choose where your Amazon "purchased music" downloads get placed. This is nice but it still does not address Amazon Prime Music that you download for offline play; they are handled separately. And Slacker Radio is a whole other beast.

The hackware you mention is an option, I've been google searching trying to find something similar. this is how I found FolderMount which almost does what I need. Ultimately, using the 12GB of remaining internal RAM seems like such a better option than all these hack approaches.

I am hoping Malaysk can comment since he has some experience with setting the partition size when he builds his custom ROMs.
[MTCB Android Head Units Q&A] Marius B:
[MENTION=3590033]Malaysk[/MENTION] for rk3188 hd some news about rom ?
[MTCB Android Head Units Q&A] agentdr8:
Unfortunately no. Android has no concept of first-boot, aside from dex optimization. And once you're inside a running rom, installing another rom from it would cause havoc (rom-ception?).

Customizing the partition sizes is definitely something the rom builders can do, but I'm not sure how much support you'll get, as yours is the first unit I've heard of that has 16GB NAND.

I think a better solution would be to bind mount your Amazon and Slacker cache directories to the internal sdcard using the install-recovery.sh script. dsa's solution should work for those apps as it does for TomTom, which also doesn't support having external files on storage other than /data.
[MTCB Android Head Units Q&A] markcm:
Thank you, I've been watching the "TomTom" discussion but didn't realized it was related to data storage location.

To copy this "binding" technique do I need to submit a request or is this something people can edit themselves?
[MTCB Android Head Units Q&A] Blankstar85:
[MENTION=3590033]Malaysk[/MENTION] any luck with kld MCU 2.55 with the radio?
[MTCB Android Head Units Q&A] markcm:
Thank you,. before I get started (shell scripts are all new to me), I have a few questions.

Once I have figured out the edits I will need for my Music player's folder binding, what is done with this install-recovery.sh file? Do I search/find/replace this file on my device and can this be done with a simple folder manager like ASTRO or ROOT Explorer?

Is there only one install-recovery.sh file? For example, can I add multiple bindings to this file or am I only allowed one binding so that I must overwrite the TomTom?

If I can add multiple bindings, do I add just the lsd line, or do I need to repeat the whole text while replacing the lsd line for each sequence?

For example, if I wanted to leave the binding for TomTom while adding a binding for Slacker would I just insert an additional lsd line similar to this:

### it will be (bind) mounted under the target folder. ###
##########################################################################
lsd "/mnt/internal_sd/tomtom" "com.tomtom." /mnt/external_sd*/*/ /mnt/usb_storage*/*/

[MTCB Android Head Units Q&A] albus123:
I read a lot of posts and wikis but still can't see through.

I have a rk3188 head unit, but what is the unit compatible to ( Android, MCU ) ? Or how can I find out?

Is Firmware the same as Android-ROM?

Here are a few pictures of the settings.
[MTCB Android Head Units Q&A] -=Gerner=-:
You have a JY unit. So, Your MCU "brand" is JY and your currently used MCU is v2.59 You can see on your attached image, under at line MCU version: MTCB-JY-V2.59
[MTCB Android Head Units Q&A] albus123:
Thanks. Is this the right thread for alternative MCUs and updates? Or what do I have to look for?
[MTCB Android Head Units Q&A] -=Gerner=-:
Yes! You are at the best, right place. Welcome.
[MTCB Android Head Units Q&A] albus123:
Oh yeah! Is there a newer or better MCU than 2.59?

Does the MCU control the (re)assignment of the buttons?
[MTCB Android Head Units Q&A] -=Gerner=-:
Currently released JY MCU files:

https://drive.google.com/folderview...haring&tid=0BxmzvLRI7-eNeVA2SWkwM1pLZ28#listv

Yes, MCU controling the right button assignment.

!!! Before You do anything! Please read carefully, all of very important informations at the first page !!!

You can try RK3188 firmware(s) from author Coudu, DSA, Malaysk. All "cooked" firmwares has been prerooted. Different type need for each HU's resolution! ... - 800x480 or 1024x600 . Can find the right links at the first page also...
[MTCB Android Head Units Q&A] UlrtraTM:
Hi for me it doesnt hide the power button or disables the single click.

I have the newest ROM for RK3188 800x640 and the neweset MCU 2.55 for my KLD2.
[MTCB Android Head Units Q&A] RinsinHero:
Ok. Also, I finally heard back from the re-seller. They state the GPS board will need to be replaced and they're going to send me a new one. Has anyone replaced this board in the past? is it very easy? I work in the IT field, so I'm pretty savvy when it comes to electronics, but I haven't opened up my head unit yet.
[MTCB Android Head Units Q&A] typos1:
Its quite easy to do, just lots of unscrewing and unclipping of cables.
[MTCB Android Head Units Q&A] devilsoft:
Yes, i test on my Nexus 7 tablet, and see if the install-recovery.sh is correctly overwritted. Regarding the lsd commands and tomtom fix, i cannot test if they are right, as I just paste the code from you :)
[MTCB Android Head Units Q&A] devilsoft:
Well, i have no spare time to check that part, sorry :( I suppose your code it's working (because I suppose it's tested by you :D), so I don't spend more time on this :)

Well, i overwrite the install-recovery.sh if "/system/etc/install-recovery-2.sh" line is not present :)
[MTCB Android Head Units Q&A] RinsinHero:
That's what I assumed. Thanks again!!
[MTCB Android Head Units Q&A] markcm:
Thank you for pointing out this discrepancy of NAND.

This is the first time I have heard reference to the NAND size with reference to a ROM version. I assumed all RK3188 came with 16GB. When I purchased the unit about a month ago, I only paid $20 extra to upgrade from 3066 to 3188 and the 16gb was included in that. MCU and screen resolution are listed although NAND capacity isn't mentioned in the ROM description(s) or even mentioned on "PAGE 1" which states:

Considering that Malaysk's ROM which I downloaded on 06/18/2015 update_4_4_4_1024X600_2_RK3188_18_05_2015 is working very well on my KGL1-2.55(with Musik) 3188-16GB unit, I will try the install-recovery.sh approach for now. Maybe this is good feedback for [MENTION=3590033]Malaysk[/MENTION] and [MENTION=4097982]DSA[/MENTION] to know that this ROM works well on the RK3188 with 16GB; with the exception of the issues I'm having with partitions for my offline music cache.

[MTCB Android Head Units Q&A] agentdr8:
It won't hide either button until Malaysk releases a newer firmware, or you replace your existing SystemUImtc.apk with the one he posted a few days back. Going forward, it should work with all of his releases.

And the single-click disable option doesn't negate the click, it just prevents the screen from going to sleep. The click is consumed and passed through as a long-press.

those work fine.

the "sync" application does not tho, it seems to do nothign
[MTCB Android Head Units Q&A] OneCheekyDevil:
Did you notice the noise after flashing a ROM or after installing any sound mods? Did you make any EQ adjustments? Does your car have auxiliary amplifiers or sound modifying equipment? (trying to determine if the fault is hardware or software)
[MTCB Android Head Units Q&A] albus123:
Didn't flash anything.

Everything from stock.

No EQ - EQ flat.

No aux amp - direct to speakers.

No noise with previous Alpine head unit.

Is it normal for some android head units to make slight high frequent noise?

Ah ok using the newest one for my RK3188 with 800x640 from the 30th June. So need to wait for the next Version. So i will take the modded SystemUI until the new firmware will be released :)

Hopefully it will include then the newest MCU for my KLD and some stuff from the new KLD update
[MTCB Android Head Units Q&A] devilsoft:
Nice sacrifice :) I can modify the app to check for that test you are talking about, and add after that (if you tell me waht is that text). Like I said before, the app already checks if you have a second install-recovery, and overwrite that one only, and not touching the install-recovery.sh (Malaysk already implemented that in his new firmware and tested). Please tell me what text to look for in the install-recovery.sh and I will release a new updated app.

Do you remember me? A month ago I had a problem with the language of the info display of my car ...
[MTCB Android Head Units Q&A] OneCheekyDevil:
The hiss is either due to the cheap amplifier chips being used in the HU, or the unit is picking up electro-magnetic-interference in the pre-amplifier circuit.

If your unit has a TDA amplifying chip, they are notorious for hissing on the outputs. The LM chips are a better quality chip.

If your unit is picking up EMI, then you'll have to figure out what electronics in the car is interfering with the HU and shield it.
[MTCB Android Head Units Q&A] devilsoft:
Thanks! I know it hurt :)

I will make another version of the app in a couple of minnutes, to detect ###devilsoft and add from there.

The rest of the functionality will be still there, so the previous versions of the firmwares to remain compatible. The idea of this app is to enable newbie users to easy build that, without touching the file.

P.S. Your install-recovery.sh already contains the ###devilsoft mark, right ? :) If not, there is a problem, as I cannot detect what firmware it is and how to add instead of replace :)
[MTCB Android Head Units Q&A] devilsoft:
Yes, but then absolutely nothing is changing :) In this case i need to overwrite the file and put my marker there so next time the app is launched, i add after that mark. The idea of that mark, is to leave the "/system/xbin/<whatever-su-to-exec> &" command remains intact. I think that idea of [MENTION=2471548]mike.s[/MENTION] was very good, by detecting if "install-recovery.sh" contains a line with "/system/etc/install-recovery-2.sh", and write in install-recovery2.sh, leaving install-recovery.sh intact. Like I said, [MENTION=3590033]Malaysk[/MENTION] already implemented that in his new firmware and works. Your idea is good too, but you need to already have that mark added.
[MTCB Android Head Units Q&A] mike.s:
You can safely ignore him. He's got some bad idea in his head and won't admit he's wrong. He wants you to change how your program works in a way which is much more complex and which has no benefit.
[MTCB Android Head Units Q&A] devilsoft:
No dsa, that's not the case. You don't get the idea. If I do that, all the other firmwares will fail using my app. Sorry, but I will not do this approach, unless the mark is already there. For instance, I don't want to upgrade my firmware, and if I run now the app with your approach, it will brake my firmware installation and need to install back...which I really don't wanna do that :) It's all about the compatibility accross already installed firmwares.

---------- Post added at 12:09 PM ---------- Previous post was at 12:06 PM ----------

I cannot ignore him :) I'm trying to explain some concepts which is the most efficient for everybody. I agree, the app becomes more complex and it doesn't need to be at this moment.
[MTCB Android Head Units Q&A] devilsoft:
Ok, i see you don't see from my perpective :) I realluy do not do any check regarding root strategies.

Maybe i'm not specialist in SH scripts, but i know in normal scripting (programming), that you cannot define for instance, two functions with the same name in the same context (which in our case, is install-recovery.sh), right? Why I say that and why I give you the previous example, with me not wishing to install the firmware again (which is also the case of everybody else) ? Well, imagine that I already build install-recovery.sh with my app, and now I want to add another service on startup, with the help of my app. Do tell me, how I detect this install-recovery.sh in my case, is a new one, and not builded already? If I add the mark now and then the rest of the script, we will not have two functions defined (like getpid() or lsd()) ? And not speaking about the other added script from prevous use of the app? Instead, I can do a check for getpid() function in sh file and if not found, or if the mark is present, then I can "add" that mark together with the rest of the script. Hope you understand now and see my point.

[MTCB Android Head Units Q&A] -=Gerner=-:
If You want to get much better recording Quality (720p or 1080p resolution), You can not use Your HU. There is no high quality connencting interface on the HU. Only a BNA type Video socket available, and that standard does not support better screen resolution than 720x576.

[MTCB Android Head Units Q&A] -=Gerner=-:
My KLD H.units doesn't have high.res capable connector interface. So, I'm sure, that basicly I can not make HD records, with my HU. I think, using an HD dashcam with the available connectors may could bee possible, but the records will be only DVD quality or less.

Using an HD dashcam trough USB, or WiFi, is another story, but I don't know our HU recording app how support this.

Update...

So, Siffion wrote a working HDdashcam. Connection type is USB. Good to know, that the recording app has support that type of connection. This device has 74° view angle. So, this is not a really "wide angle" unit.

Hi,

Thanks everyone for the answers !,

I indeed meant to attach the camera to the USB port ,

I see some Webcams (e.g. Logitech C930e) is capable of recording videos with resolutions of upto 1080p (HW compression of X264) via the USB 2.0 interface but i do not know if the HU and apps actually supports that resolution and compression.

I see this model is capable of 1080p recording , Can you achieve this with the HU or you are only recording in HD (720p) ?
