BC6 Module

Hi

I have managed to get contact with a supplier that can provide me with the BC6 module, except I need to order a minimum of 5 pieces. Cost is $18 USD +shipping.

Anyone else need / want one?

Ryan
[Android Head-Units] jpapadami:
Overall I'm interested, but I contacted my supplier trying to get one from him. I told him my bluetooth module was fried, I lied ;). As it's still under warranty, I'm trying to get them to send me a BC6 from the manufacturer. I told him that I would install it myself instead of sending it in for repairs. He told me that he's waiting on a reply from the manufacturer. If I don't get a response in the next couple of days, I'll PM you to add me in.

I think of we contact a mod or admin we can do just that.

Anyone with a VW with CAN BUS decoder have problems with the ACC power delay? When i only take off the key from ignition the ACC delay works fine, but when i close the doors and activate the central locking, the unit power off completely... already changed the CAN decoder.. no success.. any thoughts?
[Android Head-Units] shadowmike:
No can bus here but I wired mine to always have power, so I have to physically turn it off.

Sounds like a typical chevy from the 99+ era.

Acc power is constant after shutting off car until you open a door.... I hated that feature.

2.8.7 MCU

shadowmike,

Do you know what the latest MCU for this model is? I have the same the same model and am currently on MCU 4.3.2-7-10-6501, rooted on version 2.8.7.

Do you know if there is any information about the new MCU's in 2.8.7? The MCU's included with this version don't have our build number (7) and all of them have extra digits at the end. (example: 4.3.10-16-10-650101)

My model: [www]aliexpress.[com]/snapshot/314406531.html (Sorry, not allowed to post links yet.)

Many thanks.
[Android Head-Units] shadowmike:
I would not update any mcus from this update just yet. Everything works with stock mcu. I'll post 4pdas mcu information about the new update .

I will admit I have not been sober enough to understand it.

When you update the device first revision (interface with 4 widgets) firmware from Kaier (with the red button at the bottom of the launcher), you must also set and MCU from Kaier (14th revision), otherwise some functions on the SU will not work properly (loud communications, radio buttons switching, adjustable backlighting, etc. d.).*For example, if the universal State "native" MCU 4.3.10-*1-10*-210101, then it should be replaced by a force 4.3.10-*14-10*-600,101.After that, you only need to change the direction of rotation*

[Android Head-Units] shadowmike:
From what I understand though, if you have 1.x.x-7-10-2501 then you want to use a 2.x.x-7-10-2501 updated mcu...

However there is no mcu matching mine in the 2.8.7 update. I did not check the 2.8.3 or .6 updates

I'm not quite sure if you really have to change the mcu from -1- to -14- just because I've got 4.3.10-1-10-210101 with 2.8.7 and everything is working fine...

Poor quality of hands-free

Hi folks,

it´s me again. I was able to solve many problems but I´m still unsatisfied with the hands-free. When I turn the speakers to a minimum and there is no noise around the hands-free works well but when the speakers are louder or there are noises around like driving on the motorway the micro seems to be open all the time so that the other part of the call always hears the own voice like an echoe. I´ve tried to connect an external micro but the same. For me it seems to be a problem that the unit is not able to mute the micro when the other side is talking. Any suggests to solve the problem or does anyone have got similar problems? Maybe I have got a faulty unit?

I have tried several versions and right now I´m on 2.8.7 with MCU 4.2.13-15-10-6501

Thanks for your help.

Regards

Sinner

[Android Head-Units] Sinner75:
Hi Mike,

yes, I have tried that. But it is always the same. I can hear my own voice all the time when someone is in using my hands-free and I´m outside. It is really not usable that way.

As I can see you´re really busy here. I´ve bought a HUAWEI E1550 but I don´t know how to activate it. I have checked Roaming and then I wanted to create the APN but the unit does not store the settings I made. Have you got a solution?
[Android Head-Units] shadowmike:
I have not set up my 3g dongle so I am of no help.

Do you have an external Mic that you use, or the head units Mic.

However I am curious as to what unit you have ?

I usually have my volume about half way and my phone either on my lap or in the holder on dash. But my callers never said anything bad about quality , said everything was nice and clear.

screen shots

Does anyone has any screen shots of their unit that they can share? The screen shot of 2.8.6 radio look nice, I was wondering if the rest players change a bit too. I am running 2.8.7 and it has the old style radio. also is their anyway to upgrade the stock EQ, it has only a 3 band and the sound coming from my tweeters are not coming out perfect. I have install poweramp and my tweeters are now pushing out the right sounds now. I can use poweramp for mp3 but I'll like to hear the tweeters through my radio too. if anyone has a work around the stock EQ that would be great.

thanks in advance to who ever upload pic and has a work around the EQ .
[Android Head-Units] villano666:
Hi, I've recently bought one of these radios but I have a little problem. The only player I can use from the google play store is Poweramp, the other ones I've tried, DoubleTwist and PlayerPro, can't get to the SD and find my mp3s. Even if I try to browse those files is like the system cannot access to it.

The same happends when I install any other application, I cannot browse to the installation folder (a GPS app for example)

Is there a way to make this work?

Thanks in advance.
[Android Head-Units] shadowmike:
I'll look around. I think I remember seeing a 5 band equaliser but I can't remember.

I only Bluetooth stream my music using power amp to get the sound I want out of my 6x9 all around. BoomSound and Harmon kardon helps a bit from the phone.

I personally don't use cds, but I do know what you mean about wanting the same sound.

Cool and I have tried to get the radio app from 2.8.6 to work on 2.8.7 but we get force closes

The Bluetooth app does work that has a better ui from 2.8.6 the rest of the apps are the same

The only thing you can do I believe to have the other apps see your music is to swap sd in settings. The drawback is, stock GPS won't work as all the files are on the inand

Again I can't be to much of help because I stream my music using power amp through Bluetooth.

The only reason I bought a player with disk is for Dvds. A 2 year old and a 4 year old dictates most everything that happens when they are around.

Sent from my HTC One_M8
[Android Head-Units] villano666:
Hi, thanks for your reply. How do I perform a sd swap? Is that a revesal process? I mean swap, try with some player and another GPS and if it doesn't work go back.

Why does Poweramp reach those files and other players can't?

Thanks again.
[Android Head-Units] shadowmike:
It's the way power amp is programmed, the devs were smart and allowed the program to actually search for custom locations and set those for media.

As most programs only look in a certain place for music and media. If I keep my music in a folder called Chevy most programs would only look in download or music.

But because powrramp allows custom locations we can have it look in more folders to include Chevy.

Some programs are developed to search custom locations but those are the ones that usually show ringtones, notifications, etc along with the music.

Also these radios have a weird location for the external sd, some apps arnt programmed for that location.

Some users tried to symlink the location to a inand folder, but I don't know if it was successful

An21-U basic rundown: http://youtu.be/uzig9q5TQE4

2.8.7 with 2.8.6 Bluetooth app

Bluetooth and radio were the only differences.

Sent from my HTC One_M8
[Android Head-Units] kaween:
On a AN21-U ? Unlikely. Unless there are AN21 designs with something else than a ROHM audio processor.

The EQ functions of the stock app interfaces directly with the Audio processor chip. The audio processor chip on the AN21-U has only a 3-band EQ with a 3-freq treshhold point.

http://rohmfs.rohm.com/en/products/databook/datasheet/ic/audio_video/audio_processor/bd37531fv-e.pdf

So hardwarewise, a more advanced EQ is out unless the manufacturer updates this soundprocessor.

The only other route is some sort of software-based EQ (inside the App, like with most Music players, or "outside" using stuff like Viper4Android.) when you want to do it with existing hardware.

But as the sound output of the radio chip does not pass through the Android part of the audioprocessing, the radio sound itself will not be influenced.

Other than an external hardware EQ, a better soundprocessor or a Radio tuner software that passes the audio info through the Android part of the system (Spirit FM 2, ASOP) you can not change that limitation.
[Android Head-Units] shadowmike:
Thank you for the input, I thoroughly enjoy knowledge.

[Android Head-Units] roystervi:
input on Viper4Android ??
[Android Head-Units] kaween:
Hmm.

1) by design, the mic not only seems to be open all the time, it actually is. During BT calls, there's no mechanism that supresses echo/audio feedback. NONE. It does not have a Parrot-like dual mic capability that surprsses background noise.

The audio path is simply pushed directly into the BT chip, there's no processing, filtering, echo cancellation or whatever. So everything stands and falls with what mic is used and where it is placed, but also how loud the whole "soundscape" really is.

2) "Faulty unit" : possible. Can't say for sure. But no way to know for sure without testing.

3) It's certainly possible that with a VERY loud background sound level, an audio loop (echo) can be created between speakers and mic.

4) So the only way to attack the issue is by playing around with the external mic itself. (type, location). I've to check this myself, but on some android units, the external mic is (badly) wired in parallel to the existing internal Mic. This opens a completly different can of worms (wrong impendance value as both mics try to work at the same time).

What kind of external mic are you using (picture would help), where is it located, did you mod the external mic connection yourself or was it present when you bought the unit ?

I've got a pretty loud, low-cost car. I've been using a quite low-cost external mic with my unit, and I mounted it next to the light in front of my rearview mirror. The mic looks like this h t t p://www.benl.ebay.be/itm/External-Microphone-With-3-5mm-Jack-Lead-AUX-Connection-AUX-In-Handsfree-Mic-DVD-/181570701173?pt=UK_In_Car_Technology&hash=item2a46750775 (it's not the same, as I bought mine 3 years ago, but it looks like a deadringer of it). I've used that mic with 3 different headunits so far, and it never failed to produce acceptable results, although from the esthetical viewpoint it will not win any prizes. :)
[Android Head-Units] shadowmike:
I have dual exhaust on my caprice , definitely able to be heard over music, and I only use the Mic that's on the head unit, and have no issues with quality.

Doubtful. V4A needs root access.

On my S150, it would only work after a permanent root (Framaroot). But I could be wrong, just try it out, you've got nothing to loose.

In case non-root EQ is wanted, you could give h t t p s://play.google.com/store/apps/details?id=com.smartandroidapps.equalizer&hl=nl or h t t p s://play.google.com/store/apps/details?id=cn.voilet.musicplaypro&hl=nl a spin.

Hi Kaween,

at first thank you for your extensive reply. I´ve got this unit

http://www.ebay.de/itm/361094685562?_trksid=p2060778.m1438.l2661&ssPageName=STRK:MEBIDX:IT

with an allready existing external micro connection. I´ve got the problem not only when there are two (the internal and external) micros connected but also when I just use the internal. But I have to say that I have connected an extension when I placed the unit in the dash. Maybe I should remove that extension, when there is nothing connected to but I can´t belive that this could be the reason for that problem.

I have tried the external micro at several places near to the dashboard but I´ll try some more places.

I´m using a standard cheap micro but I think I´ll test another one liek the one you suggested or the one foggydew88 showed me.

At least I´ll try to get help by using the warranty allthough the seal is broken when I placed the unit in the cage. Really stupid place to seal the unit.

Do you know if there is any possibility to find out if the unit is faulty or do you mean by sending it manufacturer?

---------- Post added at 10:56 AM ---------- Previous post was at 10:51 AM ----------

Hi foggydew88,

that might be a good idea. Thank´s. Havn´t tested that yet. So you mean just to reduce the sound when there is an active bluetooth call at my mobile phone. Will let you know after work if that helps.

-> OKay, just tried to change the Soundoptions for Bluetooth but they do not effect anything. The Soundlevel on my speakers are still the same. I had a call with no noise in the background and a still standing car. When I turned the volume till level 9 there was no soundloop but beginning from 10 a clear echo. The problem is that level 9 is not loud enough to understand when I´m driving. really frustrating.

I have not tested skype or stuff. But that might be a good idea, too. But therefore I need to get my 3G Stick working. The unit will not store my APN.

Here is what I did:

1. Replaced WiFi-Dongle with 3G when unit is turned off

2. Start the unit (the lights begin to appear)

3. In the setting menu I checked the roaming button and then I clicked on "APN". Press on menu opens context menu to create new APN. Putting in all the data, press on menu to get menu with store or cancel, press on store but the apn will not appear.

Do I have to install a driver first for that HUAWEI E1550 or are they implemented. I thought they are allready in the unit because this stick should be compatible.

Okay, here is the solution for my Huawei E1550. I just had to reduce the options of the dongle like cd-rom, sd-card to modem only. You can find a how-to here:

new software

Hi shadowmike or anyone else

quick question or 2: I use your files you posted from your dropbox and I got my unit upgraded to 2.8.7 and rooted...

1/ I know now if its not broke leave it alone lol

2/ I got 2.8.7 install and rooted, if there a new version come out in the future will I lose my root access if I upgrade?

3/ instead of upgrading the whole software firmware, can I just copy the system apk (ex: radio.apk) into the system/app folder. is it safe to do this every time there a new upgrade? I did not see any changes going from 2.7.29 to 2.8.7 except the launcher. come to think about it I don't see and change from 1.9.11 to 2.8.7.

4/ if copying the apk to the sys/app is safe, can you again upload a system APK folder.

My 1.9.11 was faster loading and faster is launching apps if I can get 2.9.11 rooted. I think I will go back to 1.9.11 and just upgrade the sys/app folder.

I like to know what anyone thinks about this idea, because what it seem like (my reference) someone is is installing a skin on winxp and making it look like

windows 8... under the hood is winxp but the desktop is saying windows 8. my analogy

again thanks to the persons who are getting us these new upgrade

Though you won't need root to go back to a previous version. Just system update with the older files.

Front what I've read Android can not see the camera inputs though, so you may not be able to achive the front cam in Android.

Hi all,

I have installed the 2.8.7 patched FW available for download here. I also rooted the device and everything is fine except when I install the com.tw.service_a5a4.apk, the buttons on left and right side of the screen stop working. I have noticed that right after flashing the FW these buttons work so the problem is in the com.tw_service file I am replacing.

The previous version that was installed was:

MCU: 4.3.1-7-10-6501

System: 2.7.22

DVD: 2.13.12.2-860mc

Does anyone have the com.tw_service file which would make the red letters message go away and not ruin the functionality of the buttons on the unit?

Also, which MCU version should I update to?
