I'm glad your issue was resolved Kidmet. Sometimes it's the little things that escape us. :)

As for BT-over-Torque, I'm sure that by now you know you need a different BT module to do that (the BC6 version). It is quite easy for anyone with acceptable soldeirng skills to swap that board. After that, you need a BC6-compliant MCU to enable communication with it, and you're done. I've done it myself, it's very straightforward. Just updating the firmware will not change the non-working OBD BT situation. But in all honesty, why not go for a USB-based OBD ? Faster respons, costs next-to-nothing. The only real reason to stick with a BT-OBD is if your OBD plug is so badly placed running a cable to that location is out of the question.

If you'd still be interested in getting an OBD BT working, I'm currently trying to get those available to anyone who's interested. Other than that, running Tomtom is a legit reason to upgrade, haven't had too many other issues with the AN's that I'd consider a showstopper.

[MENTION=5024097]uziele[/MENTION] : can't make any promisses, but I'll see what I can find. Can you get me a link or whatever where I can see what kind of unit we're talking about exactly ?
[Android Head-Units] KR3W:
Wow, this thread is massive! Good to see so much support with these units. I'm hoping someone here can help me out.

I'm looking into getting this unit for my Volkswagen: http://www.audiosources.net/prod_view.aspx?TypeId=50017&Id=224&FId=t3:50017:3

1) Is this an AN-21 U? Are there alternatives to the AN-21 U's that are better?

2) Can anyone recommend another company or "brand" over the link I posted above? I like that one in particular because it looks most like OEM.

3) Is the firmware on these updatable (upgrading to 4.4, for example)?

4) Can custom launchers and stuff be used with them like on android phones?

5) Do the units turn on and off with the vehicle or does it need to be done manually? I recall seeing somewhere that the Eonon units need to be turned on and off manually (which would kinda suck)

6) The iPod cable supplied is for 30-pin connections only. Can a lighting cable adapter be used? If so, will track/artitst/album info be shown on screen and will i be able to control my iDevice via the head unit (changing tracks, navigating through artists/albums etc)?

Thanks for reading and any other info you guys can give me would be much appreciated!!!

I'm looking into getting this unit for my Volkswagen: http://www.audiosources.net/prod_view.aspx?TypeId=50017&Id=224&FId=t3:50017:3

1) Is this an AN-21 U? Are there alternatives to the AN-21 U's that are better?

The spec sheet is iffy at best, stating 1.6, 1.4 and 1.2 Ghz cpus all al the same time. Then they say it's a MST-based A9, meaning it would be a 1.0 or 1.2Ghz at best (AN21-like device)

So yeah, I would expect this to be some kind of AN21, the pics of the UI also are those of AN21 devices.

Are there better ones ? Depends on what you're looking for. In terms of speed and upgradability, the KGL/Huifei devices are a step ahead (1.6 Ghz cpu, upgradable to Kitkat). People who went from an AN21 to a KGL/Huifei did complain about the overall quality and the lower soundquality of these units. Apart from the AN and KGL's, most other devices are still in their infancy stages The Newsmy Carpad looks totally awesome, but if I look at what is still lacking in terms of features, it's not ready for primetime YET.

2) Can anyone recommend another company or "brand" over the link I posted above? I like that one in particular because it looks most like OEM.

Audiosources is one of the older ones as far as company goes. Don't think sticking with them is a bad choice.

3) Is the firmware on these updatable (upgrading to 4.4, for example)?

Nope. Or better said, theoretically yes. But I've not seen a real firmware upgrade in terms of new version for these units. The firmwareupgrades add compatibility or solves bugs/updates the system apk's, but I've not seen a higher Android version for the AN21's and I don't really expect it to happen either.

4) Can custom launchers and stuff be used with them like on android phones?

Yes, examples aplenty on this forum.

5) Do the units turn on and off with the vehicle or does it need to be done manually? I recall seeing somewhere that the Eonon units need to be turned on and off manually (which would kinda suck)

Don't know. My car hasn't got Canbus, so yeah, I have to switch it on manually.

6) The iPod cable supplied is for 30-pin connections only. Can a lighting cable adapter be used? If so, will track/artitst/album info be shown on screen and will i be able to control my iDevice via the head unit (changing tracks, navigating through artists/albums etc)?

No idea. Except for my Imac, this is an Apple-free household and I'm intending to keep it that way. :) But as far as I've read, the level of Ipod support of all these units is pretty rudimentary.

Hope this helps a bit.

[Android Head-Units] Chrisseh:
Hi there,

I've posted in this thread before.

I realise my unit isn't an AN-21 unit but the people here were helpful before so I thought I'd try again.

I've had this unit fitted for a few weeks now and it has been great however today whilst driving and using the navigation the audio cut off and the screen faded to white from the edges then to black. I then couldn't get any response from the unit at all until I restarted the engine and the unit. However now when the unit boots up there is a loud beep followed by 3 beeps. The unit seems to function okay but I didn't get those beeps before the screen went white.

Any ideas?

Thanks,

Chris
[Android Head-Units] chris.r.r:
I've now also modded the stock music app 2.8.7 to fit the design I posted in Thread #5813.

The app features large Album Art, whereas the track list and track sources can be toggled with a button in the action bar at the bottom on demand. I think it looks much cleaner now.

BTW, with the stock music app some of my songs start with a quite painful high pitch noise.

This issue doesn't appear with Poweramp. Any idea someone?

Amazing man! Did you decompile de APK? I use iPod usually and wanted to do something similar, I tried to decompile the APK but its proguarded and Android Studio can't compile it.
[Android Head-Units] chris.r.r:
A detailed how-to describing my workflow can be found here.

For modyifing source code I use Notepad++ and edit the Smali code directly. Writing some specific functions in a test project in Eclipse, building that APK, decompiling it again and look which Smali code was generated helps a lot.
[Android Head-Units] kaween:
Euh ? You're standing at the door and refuse to enter ? :) I suppose you've figured it out by now, but it really works like any other SWC button.

Press start, inidicate what action you want (in your case "volume down"), then press the hardware button that you want to connect it to (upon succes, the function will turn yellow).

When ready press "end" which should have replace the "start" button in the bottom left corner.

I wasn't aware of Music Popup, but I will defintely try out. But I do not expect that this will work, because I don't think that chinese developers stick with the predefined way how to implement Android media playback :p

Obviously it has something to do with the codec/encoding of the MP3s. I downloaded new/different Mp3s yesterday, and now the issue is almost gone (only 2-3 songs). Anyway, I try to upload one of these MP3s.

Sorry, I didn't get it ;) Are the modded radio and music app are both now working under 2.8.7 or not?
[Android Head-Units] j2gifted:
Today I noticed an issue with the sound in my truck. There is a buzzing sound that comes through my speakers when my headlights are on and the engine is running [whether music is playing from the radio or not]. If I turn off the headlights with the engine on, the buzzing stops. If I turn off the engine with the headlights still on, the buzzing stops. If I power down the radio, the buzzing stops. Ive never had this problem before...what could be causing it?

Ive had my AN-21 U for about 11 months. Its the 2 knob version and bone stock and I installed it myself.

Rear view Cam

Hey, guys!

I'm pretty new here. I was searching for a solution with my rear cam.

When the cam is plugged to the "REAR" plug on the unity, i can't see any images. However when i change to the "AUX" plug, i can see the image after manually changing to "AUX' on the unity interface. Is there any solution??

Ps. Sorry for my english, i'm brazilian... ::p
[Android Head-Units] Skratchuk:
Thanks but unfortunately that doesn't work for me.
[Android Head-Units] djblaze852002:
Are you able to get into the menu? What is it that is not working? Are you setting it to 30 minutes but it still only waits 5?
[Android Head-Units] kaween:
No problem. Your English will be far better then my Brazilian I'm sure. :)

The "rear" plug will only show an image when the REVERSE line gets 12V. Better said, the "Reverse Wire" must receive a 12V input (most people will hook this line up to the "hot" side of the Reverse Light bulb of their cars) in order to "tell" the radio it has to switch to the "Rear" video plug.

The "aux" plug does not have such a switching logic. The Reverse Cam switch works totally independant of Android : it will even switch to reverse and show a picture if your car radio isn't turned on !

Afaik, there's no way to force Rear View on the AN21's without the 12V level on the "Reverse" wire.

Hope this helps.

---------- Post added at 11:49 PM ---------- Previous post was at 11:46 PM ----------

I don't it's possible on all AN21's.

On mine, this doesn't have ANY function at all. Never has, not on the original board, not on the new board. Independant of used System version.

But as I run my AN21 of an independant power source, I couldn't care less. :D
[Android Head-Units] Skratchuk:
Sorry should have specified, i have got in to the extra menu and already have it on 30 mins.

Unit for sale

I posted a while back but wanted to post one more time before I list on ebay.

I have one of these units that the touch screen function has stopped. Everything else works fine and i actually currently have the unit installed in my car and use a mouse to operate it. The navi software normally included with the unit has also been deleted so it will not come with the unit. You can however add different ones from the market.

This would be a good unit for someone to repair, use for parts, or use it with a mouse. Don't know if it is a software or hardware issue. Currently running 2.8.8, not rooted. I was asking $115 plus shipping, but decided that may be a little steep. I would like to get $75 plus shipping, but I am negotiable. It will come with the original cables and GPS antenna. I am going to the Parrot Asteroid Smart.

Thanks,

USB Camera Support

Hi Everyone,

I was wondering if anyone had any luck with the built in "Recorder" app.

If so what camera were you using? I assume that this if for a USB camera.

When I try the app it just briefly opens then closes. I also tried "Dash Cam" from play store and it said "no uvc driver " or something to that extent. I then tried an app that was not "officially approved" it worked.

It is called UsbWebCamera from play store. https://play.google.com/store/apps/details?id=com.serenegiant.usbwebcamera

My second question is why does this app work and the others that I tried do not?

How can I examine the contents of UsbWebCamera to see what is there that makes it work?

By the way I am using a 2 knob unit (same as Shadow Mike's )

System 2.8.6

MCU 4.3.5-7-10-6501

Rooted

with a Logitech C270 and an old Microsoft LifeCam NX-3000

Ps Another interesting thing is that my Bluetooth OBD ELM Dongle now works! :good:

thanks

Hey guys we all here helping each others and share information...I have come up with a great idea for our head unit and it works...

I have added a camera to my driver side mirror so when I click on the left turn signal it will show the camera on the HU without touching the unit... The way I tests this is to add a RCA (1male output and 2 female input RCA, I will make my own patch RCA with 1 male and 5 female input) pigtail to the rear camera input.. I have notice when the rear camera get voltage then the rear camera will turn on on the HU. yes it works I have tested a house small security camera , I order 4 small N.V camera 2 for the side mirrors, one for front driving because I have low ft bumpers and one on the back glass for night driving. The rear camera will stay as is, so in all I will have 5 cameras..

1/ you have to find the positive line coming from the signal indicator before the flasher because any power after the flasher will have the video blinking on and off on the HU...

I will like any inputs good, bad or questions and if anyone in contact with the builder its a nice feature to add to the unit because most new cars are coming out with this idea ...
[Android Head-Units] comptechltd:
Good Idea. I don't have the side cameras but I wanted front and rear cameras. I installed this http://www.amazon.com/gp/product/B00B155G5M/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

And have 2 switches on my dash. My rear camera comes on when I go into reverse or I can switch on the front or rear camera manually. I also had to put diodes in the power wires so when I flipped on the cameras it didn't turn on the backup lights.
[Android Head-Units] roystervi:
I have a frond camera that is plug into the HU vid input but for the signal I want it to come on by itself.. so I came up with that idea by putting a pigtail on the rear camera input because when the rear camera sees power it put on my itself
[Android Head-Units] comptechltd:
Yes, just make sure you use diodes so when you turn on your turn signal or whatever you use to switch it on it doesn't turn on your backup lights by back feeding 12v to them.
[Android Head-Units] chris.r.r:
SystemUI has nothing to do with the launcher. To get rid of the icons use a different launcher, like NovaLauncher...

Post number #5813
[Android Head-Units] roystervi:
Yes this is what I am looking for, I was going to make my own by splicing some RCA together to make a 5 in 1... 5 input and 1 out put.. yes your right I had to add a diodes on mine because the video was jumping because the side and the rear try to come on at the same time.. So one diodes for each camera... I have lots of RCA so I can make my own auto video switcher by just adding diodes.

Google Play Music All Access Issues

Hi All,

Any Google Play Music All Access subscribers here? I seem to have trouble with my AN-21 playing anything in my library that I added through All Access in Play Music. I can play music that I uploaded through the Music Manager or Music that I purchased, but I receive a "couldn't play the stream you requested" error on anything added to my library from All Access.

Anyone else run into this or have any ideas? I want to say that I didn't have any problems before updating to 2.8.7 but I'm not 100% on that. I didn't use the app much on my radio before I updated it.

As said, I'm on 2.8.7

I've tried the whole clear cache, clear data, reboot standard troubleshooting.

Thanks in advance.
[Android Head-Units] TheSSJ:
Hi,

i've read a lot about AN21 Units and got mine last weekend and installed it right away.

I wanted to root the device, so I followed the guide with Baidu root (as I am on version 2.8.8). It rooted successfully and afterwards I wanted to install SuperSU, which asks me to download and install the latest su binary. When I click yes, BAidu asks me with the popup where I click the right option (permit) but SuperSU then fails to update the SU binary anyways :(

Anything I missed here?

regards
[Android Head-Units] Freshi87:
SuperSu needs a custom recovery I think,but there is no need for SuperSu, because Baidu managed root access.
[Android Head-Units] TheSSJ:
Hi,

thanks for the answer (and the tip) - I tried different superuser access apps and you are right - better stick to baidu...I blocked in in the droid firewall to gain internet access, which should also minimize the the risk that it installs any crap applications...

Cold weather & Bluetooth

Is there anybody who got problems with cold weather and bluetooth?

I mean that the bluetooth module on radio board wont startup while weather temperature is around under +10C°, these happened to some users and me.

Well, our Russian friends of 4PDA found the solution, there is a 2.9.3 test firmware who solve the problem (at least for me).

If you have this issue and you are brave enough :angel: try to install this firmware (it has the red UI warning), and please share you experience.

Yep, it's strange, but I found a few others "cold victim" in 4PDa and in the RedPower forum, I was fighting with these missing BT startup since October, and after I changed decs of firmware/MCU combinations I was thinking about a hardware problem (some such of cold solders), and then with this test firmware BT starts with no problems.
