Well, I do think that "Sleep" is initiated through the MCU considering you have to have to long press volume dial to actuate it. However, which system actually facilitates the function is unknown. In my opinion, the MCU and Android are somewhat integrated yet separated. For some features such as pressing Home or Back buttons on the front panel then the MCU merely acts as the trigger. Whereas, for SWC learning and playing media through the "native" apps the Android OS acts as the trigger.

Since we do not know exactly how it works, the least thing we can do is go through the gamut of possibilities before writing it off as impossible due to the "magic of the MCU". Besides, [MENTION=5617948]avgaz[/MENTION] had pointed out wanting to use "reboot -p" which technically is an alternative to the shutdown command on Linux and not a sleep function. So, I am not exactly sure what he's trying to accomplish from his broken translated English. My guess is that he wants to get the device into a lower consumption state by shutting off Android/Linux so that it is not processing anything on the ARM CPU.

Besides as reported by [MENTION=1915855]KID52[/MENTION], the "stand-by" state still consumes 1.4A which is around the 1.2 ~ 1.4A that you measured during normal operation. And, since the system boots up in approximately 15 seconds, I don't think a full shutdown is all that inconvenient.

I'm not sure what you're trying to communicate but that command is an Android keyevent trigger and cannot be "held down". You might be able to use getevent & sendevent to mimic holding down a button. But, it is tricker to use since it is device specific.

Try installing this app, Shutdown Menu 2.1. Then see if you can trigger it to shutdown using, "am start -n nappent.apps.shutdown.menu/net.dinglisch.android.tasker.Kid; input keyevent 23; input keyevent 23" as root.

Try using GPS Status Test & Fix to reset the cached data for the GPS and see if that helps.

I believe that was meant for particular vehicles whose factory radio were feed information from the CAN Bus; such as SWC controls, Temperature Settings, Parking Sensors, etc. I do not think it can be used for much else since it is fed directly into the MCU. I'm not sure exactly how much use you'll get out of them out of the "Universal" version of the AN 21-U but it is more likely to be useful in the vehicle specific models.

If you're looking for gaining access to the ODB2 information then you're better off getting a USB ODB2 or BT so that it can function in third-party Android apps, like Torque.

"Shutdown" does not disconnect and it just reboots.

I want to issue the power button on the cassette recorder through an android that would turn it off or sleep, depending on the selected mode
[Android Head-Units] goraax:
Does anyone know how the sound quality on this compares to name brand car stereos such as Pioneer, Sony etc. ? I will be using the RCA pre outs to connect to a stereo and mono amp (from which all my speakers get their source from), so theoretically all of the sound quality should depend on my amp, right?

Also, I was hoping to connect a 500GB external hard drive to this unit to use as my main music source. The hard drive is formatted as FAT32 (I'm using it with my current stereo and it works perfectly), will it work with this unit? I was planning on using DoubleTwist as my music player, because of it's playlist functionality. I'm not sure if the hard drive is powered or not, but it only has 1 connection; the usb. I tried connecting the hard drive to my Galaxy S4 via an adapter, and it powers it just fine and is able to read all of the data on it, so I'm guessing any Android 4+ will be able to handle it just fine?

Hi Guys, long time reader first time poster.....:eek:

i am considering getting one of these for my Amarok, looking at this one here (dam cant post links) ebay star_carradio, Capacitive Pure Android 4.0 For VW Jetta 3G SD WIFI GPS Car DVD Player Radio HD

am i right in thinking this is the same hardware as the AN-21-U? (same guts not facia)

the main thing i am after other than the cool features of Android is the ability to add OBD2 via bluetooth for apps like Torque etc, i noticed mentioned on this thread that its not currently able to be done with the current firmware? but i also notice on the add for the unit posted above Pumpkin_Audio is able to supply a OBD2 Ddongle and software - i have emailed them for more details and will post back here what i get in the reply

anyone have any experience with this?

cheers

update fail

Hello I have installed the 2.6.68 update but my MicroSD Card will not pick up anywhere on the dvd player.
[Android Head-Units] KID52:
Might want to edit your post to remove the entire first post quote as it wastes a lot of space.

Also, you haven't really specified any details; "the update files" could relate to 5 different system version.

However, I was concerned that the upload failed for Mirror1 of 2.6.68-complete, so is this the one you mean? If so just download the file from Mirror2, copy to MicroSD, update again, and all will be good.
[Android Head-Units] KID52:
Got a few questions about your current issue.

What MCU were you on when you installed 2.6.23?

Did changing to 2.6.23 change the MCU version?

What options were available in the model selection?

What model did you choose?

What version is MCU listed as now? (I think you mentioned "unknown" or similar)
[Android Head-Units] KID52:
Is the MicroSD card readable on a PC?

Have you tried downloading 2.6.68-complete (or a different version) from Mirror2, putting the files on the MicroSD, then turning the unit on whilst holding down the volume knob and home button? This should initiate the update.

I have fixed the corrupt 2.6.68-complete Mirror1 file.
[Android Head-Units] Djripper66:
MCU Update

I was wondering if any one has updated the MCU and where to find the latest files for it?
[Android Head-Units] KID52:
As per [MENTION=3081576]sciallo[/MENTION]'s recent adventures, changing the MCU seems to be a risky business :(
[Android Head-Units] Djripper66:
SDard

Hello yes the card picks up fine on my pc. I have 2 sdcards 4gb which i use for the updates and a 64gb for everything else now before i updated everything worked fine with all sd cards but once i updated to the 2.6.68 (does the same for other versions) none of the cards pick up the only time it does is when the sd card i used to update stays in after the update it picks up but car\nt do anything with it but as soon as i take it out then it will not pick up any of them.

---------- Post added at 01:30 PM ---------- Previous post was at 01:24 PM ----------

I have not updated MCU yet only system update from 2.6.60 to 2.6.68 but the MCU version is 4.0.6-1-10-0101 and if there is any benefits of updating the MCU i would like to but i dont know where to get the files from and which one i would choose.

---------- Post added at 01:40 PM ---------- Previous post was at 01:30 PM ----------

Just for everyone to know the only reason why im updating and rooting this dvd player is so that i can change the ext sd card 2 internal sd card so i can install a heap more stuff on it as i have got igo maps installed and that has already taken 3/4 of my space.

---------- Post added at 02:18 PM ---------- Previous post was at 01:40 PM ----------

Yes thats how i have been installing the update
[Android Head-Units] latino-7:
I tried the program GPS TEST AND FIX and it didnt work! Any other sugestions? Thank you!

Also...

Does any of you has a copy of this MCU: 4.1.0.1.10.2101 ?
[Android Head-Units] gpmg762:
FYI, igo/sygic/papago can all install to ext sd card.
[Android Head-Units] sciallo:
I'm on the road now, no notes, but even with notes, I don't think I can remember any of it as far as specifics... I think I had one of the "color" options from a newer one, I'm pretty sure updating rom didn't update MCU in any case... (let me know if any of them does update MCU) I did try to apply "model change" from tere and that's when things went weird. Also it seems like the color change is handled completely different. Sorry, I don't remember exactly how but at some point the lights behavior got weird... Either trying to use the color app from newer roms or the built in color options in the settings for that rom...

---------- Post added at 12:25 AM ---------- Previous post was at 12:14 AM ----------

oh and yes MCU and DVD versions show "unknown" (DVD i'm assuming because it communicates that version through the MCU too.

And I have to say, after ALL the messing around with MCU's and my misadventure, I wouldn't rule out changing MCU's alltogether... Just stay away from the 2.6.23 if the mcu you want is on the rom you want, just use the "model change", if it isn't (for example you want sleep on the latest rom that doesn't offer it. Identify the right one by "model change" in he rom that offers it and use that one...

Of course, that said DO ANY OF IT AT YOUR OWN RISK... If you wanna keep it safe, just use model change and not MCU update.

(BTW: still waiting to hear back from the manufacturer...)

All done but one thing

OK i want to thank everyone for there help i have finally got everything sorted except one thing which is with the app external 2 internal i have put all the settings in they all work i have also ticker at boot but the only problem i am having is that it works when i push the button beside the on boot or what ever but when i switch the car off and turn it back on it reverts to the previous storage settings until push the external to internal button again so really it just doesn't do it automatically when i restart the device.
[Android Head-Units] NickNoltePop:
Is there any chance, to change the original Apps of Music,Phone and Radio to a peraonalized app. Or to the original Apps of a Samsung Galaxy S4?

Cause when i couple my Galaxy S4 with the Radio, the contacts are sortet by number and not by name. And the mp3 are also sortet by name, but i want.to sort them by artist or anything others.

System is on 2.6.60. I hope you can help me.
[Android Head-Units] :
This would be great, especially for the phone app which is rellys crap.

But i suppose this wouldn't be easy.

[Android Head-Units] teelight:
few questions before buy

Hi,

I consider buying a AN-21 U-based car radio from ebay and have a few last questions (sorry if they where already answered but I didn't found a clear answer yet)

1. is it possible, to chance the seizure of the buttons? Is there any app or mod which allows me to customize them?

2. is it possible to get all notifications from my Note 3 (whatsapp, fb, messages, calls, viber etc.)?

3. how do i can figure out, which applications are going to work (rooted device of course) on it and which instead will not?

4. is there a way to switch off EVERY effect and all the other useless stuff? I don't care about optic and effects, i only want to have a solid und fast device, without dumb effects, animations, blinking colors and so on

Hope yo can help me!

Tommy
[Android Head-Units] djblaze852002:
1. Hardware buttons are somewhat customizable, but only work with stock apps (i think)

2. Notifications from your phone will not appear. Instead you will need to install (whatsapp, fb, messages, calls, viber etc.) to get notifications. Text messages do not appear on the unit.

3. Most apps work fine. Some apps looks funny a few apps dont work. Its all a gamble, but feel free to ask which apps youre thinking of using,

4.You can change the appearance very easily. I suggest you watch a review video (http://www.youtube.com/watch?v=BXK8epsEYWU)

Radio App / Phone App / Google Play Music App

Does anyone have any ideas what all the buttons in the radio app do? "AS, REG, TA, AF, PTY" I press the AS one and it deleted all of my saved radio station shortcuts... The others didn't do anything...

I am still unable to get my contacts to show up on the unit in the phone app.... I am on a Nexus 4 running kitkat (cyanogenmod).

My Google Play Music app seems to have a hard time playing music continuously. Has anyone else had this issue? Is it specific to me? I would like to be able to select some music or a playlist and have it continuously play (shuffle) through the tracks without stopping. As of now I am constantly having to go in and press next song or press the stop button and play again to get music to play after the first track is over. If anyone can at least confirm that they too are experiencing this. There are sometimes (very few) that music will continue to play, but I have not found the root cause.
[Android Head-Units] fcortes626:
Can some one pull the stock navigation app and upload it for me please. Some how after i updated the unit i have lost the navi app tried doing the update again and still didnt get it back.
[Android Head-Units] Black6spdZ:
Just got my unit.. updated to 2.6.68 and rooted no problem.. I'm not crazy about the animated cartoonish launcher, has anyone had success installing the kitkat launcher? I installed the three files associated with it but get the "placeholder text: google search not found" error

Update: Updated Google search in play store but now I get "Unfortunately, google search has stopped" error. People have reported kitkat launcher working on 4.1 so should be possible.
[Android Head-Units] Defender666:
The device seems to be wirless so bluetooth makes sense, but I don't think it may work in the phone app. I'm sure I need some additional software for this.

Yes I ordered the new version with ODB support so I guess they changed something to allow the OBD dongle.
[Android Head-Units] djblaze852002:
New Version with OBD Support

OBD support is one of the main features I would like with my unit. How can I tell that I am getting the new version you're speaking of? Did you buy it off ebay? I planned on purchasing this unit today off ebay until I read your post about a new version with better bluetooth OBD support... It was $330 Shipped on ebay. Let me know where I can find the "new version"
[Android Head-Units] KID52:
It's not a "new version", it's an addition.

You will need to contact Peter Chan, either through eBay or Skype, however I imagine the cost will be around $550 including the additional OBD support.

When I asked about adding it to my unit that I have already received, Peter told me it would require me to remove the existing Bluetooth module, and solder in the new one, so I am fairly confident the whole thing is Bluetooth based. Hence why it may be worth trying to search for the scanner using your phone.
[Android Head-Units] Defender666:
Actually it is a new version if it has different Bluetooth, yes I paid 550 USD @ Peter Chan, as I told earlier the 300 Dollar Ebay Reseller won't send to europe so could only order from Peter Chan.

You have just to ask for the OBD Version, it comes with the dongle.
[Android Head-Units] KID52:
It's definitely arguable, and I would argue against it being a new version for a few reasons.

Firstly, the main hardware is identical, only difference is the Bluetooth module. Same argument could be given for those who opt for the digital tuner rather than analogue, is that classed as a completely different version?

As far as I am aware, and from what Peter Chan has told me, the software is identical. Can you imagine if they have to produce different software for all the different combinations of extras?

So, it may be counted as a slightly different revision due to minor hardware options, but a different version altogether? No.
[Android Head-Units] slefff:
Same?

If you search for "Cam Android 4.1 Car DVD Player 6.2"" on ebay, 2 items show up,

only $310 and ship to Europe

Are they the same?
[Android Head-Units] KID52:
The one for $299.99 says capacitive.

The one for $310 is resistive, not capacitive.

Neither have a TV tuner, but both say 1.2GHz.

Is anyone able to confirm whether these models are actually shipping with a faster 1.2GHz CPU?
[Android Head-Units] donaldta:
I think its a bullshet scam to sell overpriced Chinese ODB2 clones that are only worth $5 to $10 dollars if that. Here's the thing about ODB2 adapters. The physical connector is connected to a microprocessor which translates the data into serial information. The datalink is then handled by another processor which usually handles Serial to Bluetooth or Serial to USB connection. So, if you have a Bluetooth USB device then in order to pair with your Android device it must either support RFCOMM or SPP (which are serial over bluetooth protocols). So, your device either supports it because of the included software stack or it doesn't. There's no reason whatsoever to "solder a new one" to support it.

It could be possible that you have a device that has Bluetooth but the developer has hidden or disabled certain Bluetooth menu from the Settings app. This was the case with the Parrot Asteroid Smart and the Volvo Sensus Connected Touch, they said you can ONLY pair phones via bluetooth. But, we found a way around that simply by using Bluetooth Autopair and we were able to hardcode the Bluetooth settings to pair any device.

The worse case scenario is that they have two versions of the ROM to facilitate this scam. One with a partial BT stack and one with the full stack. You guys should post the output of "lsmod" from a Terminal app, like Terminal Emulator. This will provide us with the information of which module/drivers are support by the underlying Linux operating system. Then we can compare one with and without this so called option and solve whether or not its a scam that feeds on your technical ignorance or not.

Just download Torque or Dash Commander which are the top two OBD apps for Android in Google Play. You can probably use it with your Android smartphone and the AN-21 car radio. Just pair the bluetooth OBD2 connector with whichever device you're going to use it with prior to starting the app.
[Android Head-Units] bmj67:
Can anyone ask peter for the software that is for the obd2.

Defender666 you said you were supplied with a dongle. Is it usb or is it the obd2 adapter. If they enabled bluetooth you should see an option to enable or disable it in the settings menu. if its not there try downloading quick bluetooth lite then try to enable or disable it.

I will try lsmod to see if i get any results.
[Android Head-Units] donaldta:

What we need more than anything is the password for usb debugging and none of the manufacturers are giving it up.

On the roadmaster software the /data/data files are hidden and can not be copied. So I can't copy the com.android.settings file to be decompiled. The other problem with that is because we cant get a file that has root privileges, we cant have it modded to exploit the masterkey bug.
[Android Head-Units] patrickoneal:
The USB debugging password, encrypted system images, lack of root, and locked down bluetooth support are kind of a deal breaker for me. This thing would be perfect if it wasn't so locked down. The Parrot Asteroid is an underpowered buggy mess. The Kenwood DNX-whatever is locked down even further. The Pioneer Appradio, even after using third party software to get full mirroring isn't good(gotta leave the phone screen on along with HDMI out and try to charge it all at the same time).

I suppose this radio is fairly new. If it gets cracked, I'll get one. They're already down to $329, but I would have gladly paid $400 or more if it wasn't so restricted.

I don't know that it would help matters, but isn't the manufacturer required to release source code for any of the open source components they used? Seems like that might help in exploiting it, but I'd bet China doesn't respect open source licenses.
[Android Head-Units] donaldta:
Looks like; Realtek RTL8192CU (Realtek USB to WiFi), NTFS_3G (NTFS support), Mali (GPU Driver) and UMP (Unified Memory Provider for Mali GPU)

Well, at least the ROM has the support. I wonder if the lack of support is due to the bluetooth hardware is present but the modules have not be insmod during any of the rc.d scripts or some other /etc script. It is a shame root isn't available for this device. Otherwise, I'd ask you to try and insmod bluetooth and rfcomm and test it with a bluetooth device.

---------- Post added at 10:23 PM ---------- Previous post was at 09:46 PM ----------

Well, yes and no. Android is actually distributed under the Apache Software License which makes it possible for them to use open-source software code without having to turn proprietary enhancements back over to the open source software community. It encourages commercial adoption of open-source software because they make it possible for companies to profit from investing in enhancements made to existing open-source software solutions. However, the underlying Linux operating system is licensed by Gnu General Public License which forces anyone who uses the Linux code to share their own changes with everyone else.

So, as long as they don't mix code sets, it would not necessarily give us the necessary information. Samsung recently got caught violating this with their exFAT compatibility code and they ended up having to release it to the community.

---------- Post added at 10:33 PM ---------- Previous post was at 10:23 PM ----------

The Settings app is actually in the /system/app directory but yeah... because the user for terminal emulator does not have the correct file and directory permissions, you won't be able to see its contents. I guess the only way to get access to it is to get root but then we end up in a Catch 22 situation.
[Android Head-Units] 4shm3x:
Ok so if the one I was going to get doesn't actually post to europe. Where would be the best place to get this? For the best price?

Don't need a tv tuner. OBD would be nice to have though.

[Android Head-Units] Defender666:
the dongle included is shown as "Landu" in the phone App. Then I need to hold down and connect as "OBD"

the provided software is then to scan and to retrieve speed and fuel level.
[Android Head-Units] donaldta:
Is this the hardware / software that you received? Landu B-Scan

Also, could you install an terminal emulator on your car radio to show us the output of "lsmod"? I'd like to compare it with bmj67's output.
