New unit Android 4.2.2 Cortex A9 1.6Ghz

Hi,

I just found this:

http://www.alibaba.com/product-gs/1653829276/HuiFei_KGL_7683G_Car_DVD_player.html

Do you know anything about that ?
[Android Head-Units] donaldta:
Nope. You're first to point it out so far. It is nice to see more and more units coming out with multiple cores and a more recent version of Android.
[Android Head-Units] pakidermo5000:
Yes, but I am afraid we will reach a point where there will be too many units and the support of the community will be lower.

I contacted the seller asking for more info and a video. They set up a minimum order of 4 units. But I guess everything is negotiable.

If I get any news, I will share.

Does anyone in here own the VW/Skoda customized version of the AN-21 U - looking like this or this ??

(edit: I just discovered that the listings state the CPU as i.MX535D, so I'm suspecting these to be OUKU based and not AN-21 U)

If so could you check and see if the illumination color can be changed via settings or a "color app"?

I tried to ask the seller, what color the light is, but I couldn't get a clear answer other than "it would match my car" (since I didn't mention the colors of my car, how would he know, right?).

It's seems VW mostly have red interior lights, but my Skoda has green, and I want the radio to match this. I've seen other VW style android radios with only red lights, and no way of changing it.
[Android Head-Units] ackyo:
i have the VW one that has the front USB hidden behind the door, i havnt noticed anywhere in the settings that refers to the led colors.

will check again tonight.
[Android Head-Units] blankers:
There is a small video on YouTube . It doesn't show much unfortunately.....

[Android Head-Units] Miwer:
That would be great - thank you.

What color is the light in your unit?
[Android Head-Units] blankers:
I have found these on alibaba. They have many versions for different cars. I have spoken to the supplier, and whilst he sells them with a minimum order of 4 units, he will supply a sample unit for $260. He will also take paypal.

I am on the verge of buying.........

I have a few issues and question with the deck. Can anyone help me out?

- Tomtom can't detect GPS. I see that I'm not the only one with this issue. Any workarounds?

- Radio won't mute or turn off (tried to force stop too, but doesn't stop) and causes other applications to be silent. I tried resetting the deck and updating with no luck. It was working fine when I first got it.

- Which GPS software works with Offline maps and can let you search for POIs by keyword? ex: Burger King (in search) I tried a few but they're either unstable on this deck, don't have offline maps feature or don't have the searchable POI (openmaps)

- Is there a way to disable the radio from starting at boot? I'd like to have the GPS software start first, then radio.

- The google maps that is compatible with our devices doesn't offer offline maps as we are 4.1 and the good framework with extra features is on 4.3

- Did you guys notice that the font looks really thin on our screen? Some lines don't draw properly. Is it because the screen is low res? It looks like the contrast has been boosted too high or something. If you go in google play store and search for apps, you will notice it there.

- When is the 4.3 update coming? I have a feeling that it will fix most of my issues. (GPS, maps, radio, contrast, etc)

Thanks
[Android Head-Units] pakidermo5000:
Thanks!

Yes, that is not much. I contacted the seller and he will send me a video soon. I will post it when I get it.

Did you ever get the TTS full voices running?
[Android Head-Units] chris.r.r:
I also own the VW version with red panel lighting (slightly different to the one you posted, mine has USB/SD on the bottom). I never found a possibility to change the color. Moreover, with the unit you posted I was wondering if there is small cover plate over SD and USB slot, then there is probably no illumination at all on that key. That would mean that only 7 out of the 8 panel keys are illuminated? That would look odd...

I installed SVOX Classic (Petra - German), which sounds much more natural compared to the system TTS. For Sygic I use Lorenzo TTS, which comes with the software... Both work without problems...

I discovered another issue with Sygic. When you drive through long tunnels, the 3D terrain view goes crazy because the route is mapped on top of the mountains, so it looks like as you would "fly" over mountaintops (quite funny in the alps). I mean Sygic, c'mon, are you serious? We have 2014, there would be ways to solve that ;) Especially because the nav software already knows that you are driving in a tunnel because it fades in a small tunnel symbol in the bottom right corner and continues the navigation without GPS... A quick search on the net doesn't reveal any solution to that (except giving up the 3D terrain view). Apart from that, it's the greatest nav software I have ever used... Sygic has no free live traffic, it uses TomTom HD live traffic. For DACH (Germany, Austria, Switzerland) it costs about 15€ per year.

BTW, another important issue I discovered regarding boot time: I only have one SD card slot. After factory reset and with an (nearly) empty SD card I get a boot time of around 18 seconds (as Kid52 showed in his video). Interestingly, when I then put music and maps on the SD card the boot time gets longer and longer. With 1 gig of music and 2 gigs of maps the unit needs 28 seconds to boot up (until radio screen pops up). Is it the same for you guys? Is it because it have to mount the SD card as internal storage on boot up?
[Android Head-Units] KID52:
Most of these points have been mentioned/addressed in this thread already.

I haven't spent much time trying after that as I've been quite happy with the standard voices and no TTS, but I'm sure I'll have another go soon as there is a new version of iGO I have yet to try.
[Android Head-Units] veletron:
I use CoPilot live which I find works fine with the built in GPS, and supports postcode/etc search. I have not tested how extensive the POI support is as yet, but it notes fuel stations etc.

As detailed on 1st page of this thread, press and hold on-screen back button on radio app, unit then boots straight to home screen. If you start radio again later, then it will once more launch at boot. Just get into habit of always closing radio app with long press of on-screen back button. Perhaps tasker can be used to auto-close radio at boot and start Poweramp/etc.

I think its extremely unlikely that these units will ever get off the current 4.1.2 version of android. All of the firmware updates thus far appear to be built on the same version of android, just fixing issues with built in functionality. This is a shame, since I am hearing that resource usuage on KitKat (4.4) is lower than Jellybean.

Aye, its a combination of low res screen and forced landscape operation I believe. I don't think it looks too bad though

A warning for people interested in buying this unit for audio quality

So after much experimentation and configuring, I have found that this unit is lacking in the sound quality department. Using this as just both a replacement Head Unit for a stock stereo system and also running from the rca outs to a 5 channel amp to a 3.1 setup, I have found no matter what I do it just doesn't sound that great.

Now I am sure that most people won't care or notice, but I do and others that are going to set this up to a decent amp/speaker/sub system are going to notice as well. I have tried tons of different software on the android side dsp/eqs/players it really doesn't matter. I don't even understand half of what the functions actually control like "LOUD" The output just isn't clean. Now I do not know if it is the hardware or something having to do with the software "enhancing" the audio output but it just gets muddy and there really isn't a lot of clarity. This especially happens at higher volumes everything just falls apart.

My very simple test to see if its the head unit or my amp/speakers/install was to just take my galaxy s4 headphone out to rca and plug it right into my amp. Using just 2 channels with no sub control it sounded MUCH better, the way it should.

While I realize the unit isn't specifically "designed" with sound quality in mind I would of liked for something with clean output. At this point I have decided I can't live with unit as I spent way too much time installing my other components in my car to not have good sound. I would say at least 30 hours in labor dynamating/running cables/making baffles etc and im still not done.

Anyway, I have not decided what I am going to get next yet(CES just happened and the 2014 double din units havnt come out yet) but I will have a perfectly functioning AN-21 for sale soon.
[Android Head-Units] omarko:
has anyone tried to connect an SSD in an external USB case to the front USB port? if yes, does it work and is the storage recognized correctly I assume formatted to FAT32?

alternatively, has anyone tried a 128GB usb stick like the SanDisk 128GB Cruzer Glide CZ60 ? Does the radio unit recognise it ?

EDIT: I tried to contact my normal USB SATA HDD but there is lot of electrical noise coming , I assume from the HDD spinning.

backup camera connection

Hey guys,

my unit just arrived today. I'm getting ready to install it and noticed something i dont quite get...

The backup camera has 2 leads coming off it, a standard power jack connection for power and a single RCA jack for video. The power jack has 2 wires coming off it for a standard 12v power + ground lead. The part that confuses me though is the RCA cable they provided also has a red wire coming out of the plug on either end.

The schematic that accompanies it shows 2 connections. Top half shows the RCA wire going to a monitor on one end, the camera on the other, and the power jack connected to the second port going to 12v and ground. The bottom half shows the RCA video cable going to the monitor and 12v + ground, and the other end on the camera side plugged in to the camera.

Now, what confuses me is the schematic does not list either/or, it just shows both connections.

My assumption here is that they attached power leads on both ends of the video cable as an alternate power connection for the camera should i chose to not utilize the direct 12v/ground power connection off the secondary y adapter lead, though to me its very odd to have 2 red wires sticking out of either end of the RCA cable and not connect them to anything.

Anyone here set up a similar camera that can tell me how its done? I'm guessing most of you saw this very same camera and have connected it as it seems to be the a-typical camera included with all these chinese import units.

Thanks for the help.

EDIT:

Sorry one more question to tack on to this:

On the unit it indicates that no video will come out of the unit unless i attach the pink parking wire to the B- (ground wire). I noticed that on the stereo wire harness there is a thick black wire and a skinny black wire coming out of the same molex connection on the stock wire harness. I connected the thick black wire to the factory stereo wire harness, and just daisy chained the pink wire (from the stereo wire harness) right back to the thin black wire (from the stereo wire harness) assuming that is what the extra black wire was meant for, though no clear directions were provided here. Did i do this correctly, and does this stereo not operate like most video screens where you need to switch the ground on and off to remove the block from the video screen (simulating the pulling of the parking break to prevent people from simply grounding out the lead to watch while driving)?
[Android Head-Units] Zittermann:
I have been searching a seller for the AN-21U in europe but without success. Does anybody have a address where to buy the head unit in europe (best in germany)? Thanks.
[Android Head-Units] veletron:
As far as I recall most folks on here have bought direct from China. Aliexpress.com. I looked for a euro seller before doing the same. Most of the units on eBay are single core android 2.3 units.

1) I assume you are talking about your LONG RCA cable that will reach from the front to rear of the car? I did not get such a cable with my setup.

It sounds like they have provided you with a combined RCA and reverse signalling cable (which is nice of them). You should wire up your camera using the power feed to the reversing lamp, then you connect up the RCA and connect that spare RED wire to the positive output from the reversing lamp (same place you connected the reversing camera to).

At the front of the car you connect the RED cable from your combined RCA/Reverse signalling cable to the REVERSE input on the AN-21 and plug the RCA into the appropriate RCA socket on the AN-21.

2) An ALTERNATIVE use for the RED lead that runs with your RCA cable is to use it to feed 12V from the front of the vehicle to the back of the vehicle this powering the camera. The GND connection will come from the screen on the RCA. Using this method, you would have to provide a mechanism to switch on the camera (a spare switch on your dash). It has the single advantage in that you could switch on the reversing camera at will without having to be in reverse. I use mine on a motorhome in this way as a rear-view mirror.

In your case, you prob just want the camera to come on and the AN-21 to auto switch when in reverse gear, so just wire as per (1) above.

I have not connected the PARK cable on mine to anything. Its supposed to disable some features when the vehicle is in motion (parking brake not on). Just leave it disconnected and everything will work.

As for the thin black wire, this pairs with the SWC (steering wheel control) wires. For most? vehicles the SWC is a three way connection using the 2 SWC cables + GND

Disheartening, I might have to wait for something different
[Android Head-Units] p64imp:
Thanks so much for your reply. Let me make sure i understand:

the power/ground connector leg is for the power to the camera, and should be tapped in to the wire going to the backup lamp lead to supply power to the backup camera only when i put my car in reverse.

The power wire running out either end of the RCA should also be connected to the hot lead of the rear backup lamp, and is to be connected to the brown reverse lead of the stereo wire harness. In doing so i will not have to locate/tap in to the reverse lead coming out of my transmission box to communicate to the unit when the car is in reverse to switch to the camera view.

I believe that makes perfect sense, but i just want to be sure i got you. that certainly makes my job easier today for sure. I located the wire on my 2003 mustang (pink/black wire running under the passenger side kickpanel), but its one less PITA wire to run over to my center console which makes me very happy! :)

Appreciate your reply too about the pink parking wire. I was going to install that sucker looped in with that thin B- wire. Sounds like that would have caused me all sorts of headaches today. I'll be sure to clip that connection before i install it!

=)

so my unit arrived yesterday:

http://www.aliexpress.com/item/Andr...er-GPS-Navigation-audio-Radio/1570938341.html

installing it today, but for a quick update, i was pleasantly surprised to find that my unit came with a rear MIC attachment out of the ipod/AV wire harness! I'm a bit bummed that the seller did not inform me of this and that i wasted $12 on a mic jack in prep to do the hardware mod, but i can't be too unhappy as i dont have to crack the seal on the unit now and worry about all those modifications.

i'm also very happy that i prepared ahead of time and purchased a parrot mic off amazon, as though the unit did come with a MIC port, it did NOT come with a mic, so it did indeed come in handy.

Going to install it today, and if all goes well to plan i'll be posting the system details later to confirm that it is indeed a a9 1gb 4.1android etc...

When i got my unit he had it on sale for 279 shipped. Looks like i certainly got a good deal for what i got!!
[Android Head-Units] veletron:
Aye. I think you have it correct. Ideally, you should place an inline fuse between the tap-off point on the reverse-light on the car and the camera. You should take the reverse signal 12V feed (the one that goes down the red wire on your RCA cable from the camera side of that fuse. Fuse should 1 - 2A.

Your unit is the same as mine, 2 knobs, volume on the right. I confirm that the AN-21 root method detailed on the 1st page works fine for this unit.

I find that the external Mic input is very low amplitude - (someone on here looked at the PCB and saw an attenuator [crude potential divider] I believe). You may still find that your extra socket wired up in place of the front panel mic gets you better volume. Mine is fine for phone use, bit hit and miss when trying to feed audio into android.

Take your time with it, there are an awful lot of wires behind the head unit when its all connected up!

Be interested to know how your parrot mic works. I have an old PC microphone hooked up to mine!

navitel?

Hi guys,

So i installed my full setup today. All went pretty well, but i'm having one issue.

I noted that they installed navitel navigator as the offline nav software, including maps to russia (he told me he would pre-load maps to US but did not). While installing apps, running out of space, and going in to app manager to try to free up space by moving some apps to the sd card i ended up breaking navitel. I moved it to the storage device and back to my head unit and it started opening with hard errors and appcrashing.

I then uninstalled the application and re-downloaded it from navitel's web site direclty only to find that the reason why he did not give me the US maps is because navitel does not HAVE U.S. maps! Shady...

Anyway, i'm now on the hunt for the best nav software i can get for my device. Any suggestions?

Also, how can i force my music apps like playerpro to find music stored on my sd/usb drives? Seems they only go as far as the sdcard storage location and do not allow me to look in extsdcard or usb directories. I'm rooted if that is any consolation to the solution...

Hi everyone. I have the AN-21 u device. But i have some problem with it:

2) My device work wery poorly when i make root

May be some of you have firmware with root?

[Android Head-Units] veletron:
I use Copilot live which I quite like.

As for music apps not seeing the SD card. That has been discussed on here many times. The android 'Media Storage' app that scans for music only looks in 'standard' locations (like /sdcard). The location where the micro SD card or a USB stick gets mounted does not get indexed by the built in media indexer. There are two ways around this:

1) Use poweramp which does not rely on Androids own media indexer - it uses its own and can pick up media from anywhere

2) Use a remounter (root required) to remount your SD card somewhere where the built in indexer can see it.

I chose option 1.

Nigel
[Android Head-Units] PsychoMcSatan:
I'm running that same MCU, but I've just now noticed that bluetooth is a little messed up. My phone still connects, but to the old name and old password. It's like the bluetooth app is no longer communicating with the bluetooth hardware. If I change the name or password on the radio, the phone still sees the old name/password.

Despite the connection being established as reported by my phone, the radio doesn't see a connection and calls don't get routed.

I've updated the system software to .70, but still the same behaviour. I'll try a couple more MCUs and see if I can find one that makes the bluetooth work again.
[Android Head-Units] sciallo:
Ouch,

As I explained in the wiki page, the bluetooth is it's own board, with it's own memory. sounds like yours is not the same as the rest of the units and it probably communicates with the MCU and android in a different way

Kinda seems like the right MCU files for your specific unit (vol. on right, tuning on the left) were not included in the updates... Hopefully I'm wrong and you find the right one, otherwise, I suggest EVERYONE that has that particular unit starts harassing your seller as well as the manufacturer until they publish the right one...
[Android Head-Units] booba5185:
I have one of these An-21s and so far it seems to have a lot of potential. I haven't done anything really to it other an root it and install Power amp, but I'm having some problems with it. I'm trying to get Power Amp to open on startup, the radio app to close (it always seems to open on startup), and Power Amp to play on start up. I tried Llama and it won't work for me at all, no matter what I do. Also, the video player has everything at the wrong aspect ratio, so I'm trying to use MX player, but it rarely works correctly. Finally, I'm trying to use Car Home Ultra as my launcher, but I can't get the home button to launch it. I found an app that says it'll do what I want but the play store says it's incompatible. Any ideas? Thanks for all the help guys.
[Android Head-Units] ackyo:
Hi Mate,

i can confirm there is no option to change the LED colors.

on another note +1 for CopilotLive works great! i tried Navigon (came with the unit) Sygic and google maps with my phone hot spotted.

Copilot just seems to work best for me
[Android Head-Units] gpmg762:
You can try Tasker, I use it to launch Car Home Ultra after boot. The Home button always brings it to the default launcher Home,

even if you set it as temp home (suspect it is some how tied to the MCU).

I use back or a Car Home shortcut on the Home screen to get back to Car Home.
[Android Head-Units] booba5185:
I'll probably try to have tasker open car home and power amp, but for now I need to find away to get llama working to when I can get power amp to open, it starts playing right away.
