starange sounds while playing mp3files

Well, I just got this unit installed and the strange noise is similar to the slip sound while playing a scratched cd but I am playing mp3 files so no physical damage is possible. The first thing comes to my mind is the unit is having some memory issues. Not enough memory? or the codecs are old or defected... I just reset to factory defaults and will try again... but it seems I lost almost all the apps... gotta reinstall them first... and then I will try to root it and see if any change will come around.

I've got the same problem when playing mp3's in stock music player. It's software problem I suppose. But I've switched to Neutron, it's the best one for my incar use.

Why cant I choose the music files in SDcard or USB drive through the standard/others?

another issue I am having is choosing the files to play in the music players... they only show the files in a folder called 'Inand'

to play the ones in sdcard or usb drive I have to go there and click them in which case I have to play them one by one... strange things with this unit...

hi,

I have updated and then rooted but still cannot copy thea4a5. apk file into the system/app folder... it does not let me... it is asking for root privileges and I say yes.. it starts the copy process and then fails.... I don't know why... any ideas??

Hi all

this has been one amazing thread so thanks to all for the valuable information

I bought a Peugeot 508 specific Android GPS.... reading through this thread; and trying the various passwords recapped in the first thread has lead me to believe it is same core components

the 123456 password for and the factory reset password and the john@tw-desktop password all worked like a charm

however..... I seem to have some issues I can't seem to fix.

The GPS I bought was this:

http://uploaded.net/file/jtzmpslv/000WE1.3.2.rar

Ignore the specs... It is really the following from the settings page:

CPU Information: Corex - A9 Dual Core

RAM Information: DDR3 1GB

Android Version: 4.2.2

MCU Version: 4.3.3-11-91-4501

System Version: 2.7.32

DVD Version: 2.13.13.1-860mc

All this will most likely not be super useful with what problem I have:

1. I am unable to root - tried both solutions on page 1, but none worked. In fact the first option (using the RootMyAN21U.1.4.apk) after Step 1 made my screen all black - and dark... hardly readable and the keyboard was all black so I had to type to terminal commands in the dark... and whilst the su commad succeeded; I was unable to delete the file as it gave an error in terms of userrights.... leading me to believe the root failed. That said - I had to factory reset (again in the dark to type the password to factory reset) to regain visibility and fix the visual bug.

2. I can not get rid of the radio app... when ever I cold start the device (i.e after a while being turned off) - the radio app shoots up tuned to FM 87.5 which is static noise... and at a loud volume (15)

I have to wait for the full think to boot before I can turn that off.....

I tried replacing the radio app with the one found on http://androidstereo.mobile.eu.org... which looks better too. But after every cold reboot, It is back to the original one - this is the main reason I wanted to root, thinking maybe that will allow to permenantly replace the radio app.

I have quit the radio app by pressing the button on bottom left... but it doesnt change the behaviour. It is still the first app that loads up when i power the car and it starts the static noise (87.5 FM) even before Android is finished booting....

This all would have been less of a problem if my canbus was not defective and I could lower the volume using the buttons on the dashboard... but I have to wait 15-20sec for android to boot for that to happen.... trully frustrating!

any advice would be welcome.

New Model

I've been reading all double din android devices before hooking mine up and I have come to the conclusion that I have this model. (The password from the first page fpr developer options and USB debugging worked, as well as the same specs, but much different face than what is on the first page or wiki) With that being said, I have a ton of updated software (which I'd be more than happy to try to pull from the device if someone walked me through it). Right now I have

Cortex A9 ual core

DDR3 1 GB

4.1.1 Android

MCU Version - 4.2.15-1-10-2101

System Version- 2.7.9

DVD Version - 2.13.11-hd860mc

I have a few questions, but I'll see if anyone is even still reading this forum first.

Hi all!

i've got a problem with bluetooth. The BT app works well excepts it does't always autoconnect. My autoconnect setting is to open, but I tried close also. While I'm in the app, the bluetooth stay connected but disconnect when I open another app (any app, Music, radio, Chrome...)

System autoconnect itself sometime (without going into BT app) but it's like 1 time on three... And still, if I open the BT app then close it, it disconnects.

I have the two knob & 8 buttons model, with DVD.

I updated to system 2.7.29 but I had this problem with the 2.7.22 which is my original version

My MCU is at 4.3.1-10-10-2501 but I found no newer version on the repository. I'm searching for an answer since 2 days without any luck

If anybody can help, it will be greatly appreciated!

when i touch screen it selects different part of screen. need to set screen back to default.

can access the screen and settings via a usb mouse.

been trying for days and now at a loss.

help really needed

thanx in advance please
[Android Head-Units] Kidmet:
Ok, played with my unit for a while today. Here are some questions I have:

1) I see people have the backup camera working. I tried to do it, but no luck yet. I have the video out to the camera in, and I am pretty sure I tapped the right wires for the positive and ground at the reverse light. I will have to check more tomorrow.

2) The clock is a huge issue. How do I set it? I heard it went of GPS. I get GPS signal in google maps, but the clock is still wrong.

3) I rooted it, so is there a way to change the profile so everything shows up in google play?

4) anyone have an amp set up to it? I did a y-connector to the blue subwoofer output but I have no sound.

5) Steering wheel control (I have a 2008 Nissan Altima) I thought I tapped the right wires for key 1 and key 2, but I have no steering wheel control. Is there a ground I am missing for this?

6) I hate the native launcher, anyone know a good launch to make it look like an android device. (one that I have have widgets and such). How do I get it to launch instead of the native launcher?

Other than these issues, I am super happy with the device.

2. To set the clock turn off auto to manual in settings

4. I have an amp setup and working so I would suggest messing around with the wiring some more.

Here to Help Dude

Hi mate

See my post #4501 on 18 July 2014. I wrote that to help people in your situation. The exact same thing happened to me, which I call a "near brick experience".

The problem is that the official root method is outdated and I would say dangerous, because of a near-unusable black screen. Why hasn't anyone updated the Wiki yet? I asked people to do this. Is the moderator around these days?

The only thing that salvaged my situation was the Baidu root. Your situation is a little different as you are using the newer 2.7.32 firmware (I've heard that Baidu root may have issues with .32 version). My suggestion is that you flash the 2.7.29 firmware instead, as I can tell you for a FACT that Baidu root works with that version. If you want to upgrade later, do so. I got rid of the UI unauthorised message as well with the modded .APK file. Once rooted, I could execute all the "su" commands and delete the local.prop file as required. 2.7.29 is a stable build. I'm not sure what the advantages of later builds are. Can anyone list them off quickly?

Radio app - yeah it's pretty average, isn't it? But you can auto-program the stations and then the car starts on the last tuned station, not 87.50. If you quit the radio app to the home screen, and then run the DVD app with no DVD in the drive, it will shut off the radio sound. If you reboot the car in that "state", I believe that the radio app won't auto-start. Give it a try. As for how to replace the radio app, I would also appreciate advice from someone else on that. Even better is how I can reprogram the "Radio" hardware button to run a custom radio app. At the moment, the only hardware button I can reprogram is "Navi" which I have changed to Google Navigation.

Hope that helps.

Cheers

Thanks mate

I am not sure which device I have - hence the reluctance to change firmware... plus my device is a model for the Peugeot 508

http://www.alibaba. com/product-detail/Peugeot-508-radio-navigation-systems-gps_1930246844.html

i:e it does not have a slot for SD Card - nor does it have any buttons and relies upon the cars dashboard

I am still waiting on the Canbus replacement to see if the buttons work - so far they don't...

I have tried all suggestion to kill the autostart of the Radio - no luck

I am guessing reading in one of the thread here that it might be the power cable killing off totally - but since my device came with the standard car connector, I remain reluctant to cut and paste any wires around.

I thought it could be resolved via software.

Without an SD; what are my options to recover from a failed flash ?
[Android Head-Units] Miwer:
You both should be aware, that the stock apps (Radio, DVD, BT, AUX, IPOD and so on) closely interact with the MCU in the unit, in a way that is not generic to Android. You will likely NOT find any app that can handle this communication, unless it's specifically coded for this unit.

As for the Radio starting before Android: That is the MCU who's responsible for this. Since the last started app was the Radio, the MCU immediately tune to the last used radio station, and switches sound source to the FM tuner inside, before Android even starts up.

Also you cannot reprogram the hardware buttons (with the exception of the Navi button) - because like the stock apps, they are handled by the MCU. When you press a hardware button, the MCU signals a service app in Android about which button is pressed, and the service app launches whatever app it's coded to. If you know what to look for, you can probably disassemble and hack this service app to launch other apps.

Yeah that should fix the radio noise before Android boot. You can use any of the stock apps that switches the audio source to anything else than the FM tuner (IPod, AUX, DVD, Music).

[Android Head-Units] kaween:
Hmm. I've been working on my car this weekend, and suddenly Rocketplayer "lost tone" too. It came back after reset. However, I noticed WHY Rocketplayer lost audio : it would seem this happens when the AN21-u looses power at a critical stage during cranking or whatever happens to in your car that temporally cuts the power to the AN21.

I run my AN21 from a mini-ups battery supported unit, to avoid reboot/restart of the AN21 during starting the car. Normally, my AN21 NEVER is cut from its power source this way. However, this weekend I had been running the extra battery to depletion, and as I turned my ignition key, the AN21 didn't have a battery-backup anymore and promptly rebooted : audio was gone (in Rocket player, so that's a similar issue as you reported in poweramp)

I tried this a couple of times, and I can reproduce the situation : whenever the AN21 is "suffering from a reboot" due to powerloss, there's the possibility that Rocketplayer goes mute and stays mute till you reset the unit. I wouldn't be surprised if Poweramp show a similar issue, and it explains why I never suffered from this issue as my unit is constantly being backup-ed by a secundary power source.

By the way : I now only noticed Rocketplayer supports SWC control even without the "go to radio and exit" routine. (non-canbus, self-made analog SWC control connection).

I also only now noticed my AN21 supports OBD over BT. I've tried this in the past and it never worked. This weekend, after experimenting with that "loss of sound" issue and resetting the unit numerous times, I noticed my wife's BT OBD was beeing seen by my AN21 .... and it did connect with it. No idea why it failed it in the past, but I'm glad it works.

I now have another stupid problem. After rewiring and reconnecting my subwoofer and cleaning up the cable loom, it now turns out an incoming call on my mobile phone is beeing picked up by the subwoofer's electronics, resulting in a horrible "kr kr beep beep" in the background prior to accepting a call.. So my ugly makeshift cable hookup did not suffer from this, and after I put everything under the carpet and cleaned-up the installation, I'm now hearing all that mobile phone traffic. :rolleyes: Back to the drawing board. :p

It's no problem all about learning. As for launcher I'm using the firmware without the built in widgets and then adding my own widget's that I need. If you don't want to do that would as suggested b4 use nova launcher from play store.
[Android Head-Units] guano30:
Yes Mate you are right!

I recognized same that this Issue only comes when you switch the Ignition and Radio loses Power.

Funny that the Stock App and Radio dont care about and have Tone whatever happend.

Since i change Stock App with Poweramp by renaming i can get back Tone by switching to Radio and back.

But its really strange.....

So sad that its impossible to contact Devs of that Units to get a Goal together.........

Even more sad that the Code is crypted....
[Android Head-Units] Kidmet:
Yea, I have more updated firmware and such than everyone else, so I am hesitant about losing it. (It's really great actually and I haven't had an issue yet) So I will check out nova launcher.

---------- Post added at 11:09 AM ---------- Previous post was at 11:03 AM ----------

1) Ok, I got this working. My HU has a wire that says reverse on it, hooked it up to the positive to the reverse light and it worked like a charms.

2) Turned off automatic time zone and set to my timezone, clock works perfect.

3) Found the apk installer website, so I can just load apks from a flash drive, no biggie.

4) Rechecked the install and the plug for the amp and camera (and a few others) ended up getting unplugged when I mounted the HU. All fixed.

5) Steering wheel works great. Had key 1 and key 2 and then found the ground on my harness for the SWC and used the ground from the back of the HU. Fixed.

6) Going to test Nova Launcher in a few here.

Hi Miwer

Yeah u can!

Just hacked ALL the hardware buttons! ! This works from the boot level also.

Go to Settings, General, Extra Settings, pw=123456, Panel Keys

1 . Press start. It goes yellow.

2. Press function u want (bluetooth menu is stupidly called Answer). It goes yellow.

3. Press button u want. Yellow disappears.

4. Repeat process as necessary

5. Press end

(You can also program buttons to do different things for a long press, repeat, or super long press by pressing the function for longer in step 2. A sub menu appears). For example on my model I dont have a menu button but I have a mute button so now I press "mute" to mute and I "long press mute" to get menu function. Cool, hey?

Still working on custom app for each button ... hmm not sure about that.

Sorry if this was already posted in the 5000 previous posts. I just stumbled on this.

Anyone know how I disable the screen dimming with headlights (on the device). I have tried setting the extra settings option for illumination to CLOSE but that only affects the buttons, not the screen which still dims when I turn the headlights on. I have twilight and tasker so can do it that way.

I assume I could just disconnect the (orange?) headlight wire on the loom but I am trying to avoid pulling the whole thing out.

Thanks

As for your camera idea, how about a RCA switch. Then you can just change the input into the "button"
[Android Head-Units] Black6spdZ:
that wire only affects the buttons unfortunately.. to do what you're wanting download an app that automatically adjust the screen brightness based on system time and set it to dim after dusk and full brightness after sunrise..done!

Not on my unit. As I said, the screen does dim with the headlights, that's the problem. If I change the setting in the extra menu it only affects the button highlights. The screen is always dimmed by the headlights.

[Android Head-Units] Malcez:
Kidmet - thanks for the RCA switch idea. Brilliant. Now, I refuse to believe that you have no bluetooth menu. Can you post me a screenshot of your device (including all buttons) and one of us can walk you through it? On my device there is a hardware button labelled "BT" for bluetooth. Even if you don't have this, you can program a spare button to do this (or a long press of a button already in use). See my hardware button hack post. Remember, the bluetooth menu on the AN21 in the hidden menu panel key assignment matrix is NOT CALLED BLUETOOTH. For some really stupid reason, they have called the Bluetooth menu ... wait for it ... "ANSWER".

Once you are in the bluetooth menu, you will see that it is simply awful. The submenu you need is the icon which looks like a mobile phone emanating bluetooth waves (sigh!) There, you will see all your bluetooth pairings. You can scan for nearby devices on that submenu. Remember to make your devices "discoverable" for 2 minutes (such as smartphones etc). My OBDII has no buttons on it, so therefore is is ALWAYS discoverable, and there is no "1234" or "0000" which gets handshaken to/from it. It just pairs without question.

Look man, I hope that helps. I'm sure we can get you sorted.

Bluetooth Multifunction

Yes, I can confirm that while Torque is running, and sensing, I can play bluetooth audio from my smartphone. You need to go into the bluetooth menu and hit the audio submenu and then the play button to fire it up. After that, it can be played/paused from the phone itself, I have found.

I believe that answering a bluetooth phone call while Torque is running will also work.
