All I know is "Mongolian Beef, Honey Walnut Shrimp, Ma Pao Tofu, Wor Wonton Soup and four orders of rice, please". But, I'm not sure how much that will help you in this situation.

I'm pretty curious about the kind of Android errors that you're getting in the background after it boots and every time it force closes on the different native apps. Would you mind uploading the output to the following command after rebooting and executing the various options?

$ [COLOR="RoyalBlue"][B]su[/B][/COLOR]
# [B][COLOR="RoyalBlue"]logcat -dv threadtime -f[COLOR="DimGray"] {/path/to/usb}[/COLOR]/logcat.txt[/COLOR][/B]

It would also be nice to get an idea of the sequence of the apps you tested too.
[Android Head-Units] sciallo:
Will do, probably tomorrow... I guess I'll have to root it again for that uh? ...not the easiest without buttons and working aux app but doable :)
[Android Head-Units] amc_oldsarge:
OK Guys

I've been lurking on this thread for quite a while. Guess I'm going to jump in.....

I bought the AN-21-U Unit in mid December and installed the unit into my car during the Christmas Holiday. I wanted to get some feed back on a few items I have discovered.

First off, my unit is Rooted [Thanks for that]. I have installed the Apex Launcher, which is what I use on my S4 (which I love).

The Unit is quite snappy, no hesitation in changing apps or swiping screen. :good:

The audio level from the Radio and/or CD\DVD Player is about 10-15% louder than Music App. <<No big deal, but odd.

In the radio app, AM Favorites are +/-001-004 more or less than the station really is. For instance, 740am shows as 738 (-002), 950am shows as 954 (+004). Has anyone else experienced this? :confused:

The radio is pretty good. AM quality is sub par when compared to a stock radio, but not as bad as many big name brands out there. FM sounds great. It would be nice to be able to manually edit your favorites.

The Music player is adequate, but could be MUCH better. Too much real estate is dedicated to song details and not enough for the songs in your current directory. It would be nice if the names would scroll if they exceeded the amount of space available. For the life of me I can't figure out how the songs are listed..... All of my songs are titled with the track number, then the name, but they seem to appear in a totally random sequence. Anyone have any hints on getting them to appear in their correct order? I understand that album art is now working (with the latest version) but what format rules are required to get them to appear?

In the iGo MyWay Navigation App the maps themselves seem fine. But in my case the verbal directions are very choppy. It's as if the app is looking for the next wav file to play. Its hard to listen to... Anyone else experiencing this? Also, I'm not a big fan of Dave, I've tried to change it to Kate, but when I press the back button, the app crashes to the desktop....

Has anyone tried a different Nav App from market? Is MyWay the best available? I also have the Sygic Nav app installed, but only have the Russian Federations maps, is it worth buying the North America Maps?

Has anyone gotten the AXXESS ASWC-1 Steering wheel control to work with this unit? I have one and I'm getting input, but when I exit the General\Steering Wheel Control, the default apps fail to respond.

Has any U.S. owners looked into a G3 USB module for Internet Access from any carrier? I know that the list of compatible adapters is short, but not sure if they are even compatible with US Carriers like Verizon/Sprint/AT&T/Clear.....

I really think we need to petition XDA to create a forum specifically for these Car Stereo Android Head Units. Having one HUGE thread is getting difficult to find information. I've already made a request, but if others do it also we might get more traction.

Thanks for anyone willing to respond to my litany of questions!!!!
[Android Head-Units] nikko82:
I'm having an issue with my unit.

I have a model with a VW faceplate and it comes with a CAN module.

When I turn off the ignition, but keep the key inside, is stays on as expected. However after some minutes it starts blacking out and coming back on. When it blacks out the screen goes black and the sound disappear. Then, when it comes back on it has switched audio source to FM. All the apps are still running, the unit isn't rebooted. This blacking out will continue until I turn the ignition back on.

I suspect it might be a problem with the CAN module, as the ACC-signal is coming from there. Have anyone else experienced this?

I'm also unable to connect with USB to my PC, both with and without USB debugging enabled. When I connect the cable to the front USB connector nothing happens. Is that where I'm supposed to connect? Do I need a driver?
[Android Head-Units] donaldta:
Doesn't a USB keyboard work in place of those front panel buttons?

---------- Post added at 06:16 PM ---------- Previous post was at 06:07 PM ----------

You can always connected via WiFi. In a terminal window do the following commands

$ [COLOR="RoyalBlue"][B]su[/B][/color]
# [COLOR="RoyalBlue"][B]stop adbd[/B][/COLOR]
# [COLOR="RoyalBlue"][B]setprop service.adb.tcp.port 5555[/B][/COLOR]
# [COLOR="RoyalBlue"][B]start adbd[/B][/COLOR]

As far as connecting a USB cable, I'm curious as well. I think all the ports on the AN-21U are host ports. In order for adb to work over USB, it needs to be connected with a client USB port. I'm not sure if the port in the front has that capability to switch mode. Is it a micro or mini USB port?

[MENTION=1537970]sorin129[/MENTION] has and reported it in Post #934. You do have to program the Axxess ASWC-1 seperately then program AN-21 U's SWC in order for it to work. Have you been able to get any of the "Reserve" functions to work?

Btw, are you sure that you need the Axxess ASWC-1? What kind of car do you have?
[Android Head-Units] cyberpapa3:
I got the ASWC-1 to work with my 06 Civic EX. You have to program it as #11 METRA OE. Then program the buttons on the head unit. I used the "KEY 1" wire in my case. The wire from the ASWC-1 that connects to the head unit may be different for your vehicle but I used the Brown wire off the 3.5mm jack. Hope this helps.
[Android Head-Units] donaldta:
Heh, heh. Thanks. The problem with not being root, is that logcat can only report on what the user id of the terminal app can see from the Dalvik virtual machine. That's why root would be necessary to log all the processes on the system.
[Android Head-Units] mcsvt:
I've used the iGO navigation a few times now and I have the same choppy verbal directions. I agree the maps are pretty good though. I haven't tried any other nav apps, I do have google maps loaded to try out..
[Android Head-Units] KID52:
The voice on the version of iGO I installed has been perfect, no choppiness, hesitation, or anything.
[Android Head-Units] jakejm79:
Is the radio region set correctly in the extra settings menu?

---------- Post added at 10:22 PM ---------- Previous post was at 10:19 PM ----------

Looks nice, though personally one of my prerequisites is a physical volume knob.
[Android Head-Units] amc_oldsarge:
OK, maybe that is my problem. I have the Key-1 wire to the brown wire on the 3.5mm jack and the Key-2 wire to the brown/white wire on the 3.5mm jack.

I read on a post on the OUKU Head Unit that a owner had used both wires on the jack with success. Maybe that is not the case. Like I said, I'm getting output from my SWC via the ASWC-1, but nothing really works. I'll give those settings a shot. Thanks!

---------- Post added at 10:26 PM ---------- Previous post was at 10:20 PM ----------

What version of are you running? Mine shows as 8.4.3.1.179971 (April 17, 2011) << Which seems old. :confused:
[Android Head-Units] KID52:
iGO Primo 9.6.22.297071
[Android Head-Units] tarzansg:
Opps..now some stuffs are different, my unit navigate this way :

settings->general->extra settings-> (this is the end, and no other options to choose, only a text box cursor prompt to enter some digits, and a cancel or ok option. The prompts only accept numbers, no alpha character allow.
[Android Head-Units] KID52:
"123456"
[Android Head-Units] amc_oldsarge:
Can I ask where you got it?
[Android Head-Units] KID52:
A small island inhabited by pirates.

Edit: Actually, I don't think I did, I got the maps from there but the actual APK was a pain in the ass to find a version that actually worked with Android 4.1 as apparently the sound is a known issue.
[Android Head-Units] amc_oldsarge:
:good: Thanks, that was the issue! Thanks to KID52 for the P/W. Why would that menu be locked down?
[Android Head-Units] KID52:
No idea, especially since the password is included in the manual they send with the unit :)
[Android Head-Units] amc_oldsarge:
OK, I guess I could go looking on that island also, unless your willing to share it?!?!?! I have an FTP Server that I could give you credentials to if you willing. I could give you an invite to revolutiontt.me if you desire. ;)
[Android Head-Units] tarzansg:
Almost all the screen shots of my apps are shown in the my seller page (except for the "recent apps" and the other home screen showing 4 different apps are not available in my unit, I will try to contact my seller to ask if those are even available in my unit thru some setting or firmware revision.

Here is the seller page again :

[Android Head-Units] amc_oldsarge:
Guess its official, I'm an idiot. Somehow missed that. Duh! Thanks for the hint!

---------- Post added at 10:50 PM ---------- Previous post was at 10:46 PM ----------

Just a general hint for those users who have their head unit installed. VMLite VNC Server (available is play store) is an excellent app to allow access to your Stereo from the comfort of your home. It is a pay app, but well worth it IMO. I also keep my car on a charger when working on the unit.
[Android Head-Units] KID52:
It's uploading now, will take me a while though.

Ah I see, apart from the homescreen, system 2.6.40 has the same red themed apps.

Haha, nah, considering 90% of the manual has no relevance to this actual unit, I don't see why people would bother to read it. Although I guess the Engrish is good for a laugh.
[Android Head-Units] amc_oldsarge:
I have a 2008 Saturn Vue. I'm 99.9% sure that I need the ASWC-1...... But I've been wrong before, in fact tonight.
[Android Head-Units] tarzansg:
thanks man ! nice info about this app.
[Android Head-Units] tarzansg:
Thanks sciallo for sharing this, its really amazing that now i realized about this customization capability !

Thanks to KID52 for the password too, i dont recall seeing this in the user manual, maybe its not even there.

i have completed my customization of the panel buttons, screenshot attached.. now i am able to go to the Recent Apps !

Thanks guys !

I have some other questions, any info about what does the "Menu" button do? Thought my unit does not have a Menu button on the panel, but i set Menu in other button does not do anything. And those stuff like Panel up Panel down.. does not do anything either.

What about the "Model Choose" option? Have anyone tried that? I am a little hesitant to try that as i am afraid its irreversible. That are 4 car models to choose from 2 for VW, 1 for CRV, and 1 for Camry. Sceenshot attached.
[Android Head-Units] tarzansg:
Is this the home screen that you guys are having? i saw some post about pressing the home screen bring you here? Screen shot attached.

Or does the panel up down bring you to this screen? My unit does not have this feature, as in having all 4 apps running and showing in a single page/screen. I would be nice to have this though.
[Android Head-Units] KID52:
"Menu" is the standard Android function. Works in most apps to bring up, well, the menu.

Some firmware versions have this design, such as 2.6.40, 2.6.60, and 2.6.68, but 2.6.60-2 and 2.6.62 have a different design, there is a picture of this on the main post in the "Changelog (Unofficial)" section.
[Android Head-Units] tarzansg:
Thanks KID52 once again ! Hopefully someone else could comment about the "Model Change" feature

I saw there is already a System Version 2.6.68 available? I think someday you will probably find some time to update the changelog over there, but i think i read the changelog in some page of this thread.

Do you actually have a copy of System Version 2.6.64 rar files? Because my unit is running this version, and how can i keep a copy of this system version in case i would like to roll it back after i have upgraded or downgraded to other versions? :cowboy:
[Android Head-Units] KID52:
I don't think anyone knows right now exactly what the model change feature does specifically, but the main use appears to be switching between two models, those with "Color" or "Sleep".

Models with "Color" allow you to change the button colour on units like the one you have.

Models with "Sleep" allow you to hold down the volume knob to go into a sleep mode, but this still uses ~1A so seems pointless.

I do not have 2.6.64 files, and as the updates are believed to be encrypted there is currently no way to create a backup that can be installed at a later date.
[Android Head-Units] donaldta:
You're good. According to Axxess, your requires a single digital line (pink) for the SWC, so the AWSC-1 was necessary. Are you still having problems? What exactly do you mean? And when you say that you get "something" from the SWC, what exactly does that mean?

Did you notice that [MENTION=5617942]tarzansg[/MENTION] has a newer MCU version and different options in his screenshot in Post #1079?

VW(4.1.0, RDS, AD, Color, Rohm37534, TEF66X)

VW(4.1.0, RDS, AD, Color, BC6, Rohm37534, TEF66X)

CRV(4.1.0, RDS, AD, Color, Rohm37534, TEF66X)

Camry(4.1.0, RDS, AD, Color, Rohm37534, TEF66X)

I wonder what AD and BC6 could mean.
[Android Head-Units] :
Hey guys,

im searching for a "frame" for installation in a double din frame.

Something like this:

Do you have a link for me where i can buy this frame?
[Android Head-Units] PsychoMcSatan:
Do a Google search on "double din dash kit" and find one that matches the make and model of your car. Though as I've posted before, the double-din opening on these kits appears to be slightly smaller than these Chinese units so I needed to shave off a couple millimeters.

Does anyone know of dash kits that would adhere to this Chinese double din standard?

Actually, I can only confirm that the OUKU style bezel is slightly larger than standard double-din. I'm curious to get to the bottom of this standards issue.
[Android Head-Units] KID52:
According to Wikipedia, the standard is 180mm x 100mm, but if that were true, then this unit would fit fine.

It appears there are two "standard sizes", 178mm x 100mm, and 173mm x 98mm. But for the life of me I cannot now found where I sourced this information...

I think this unit was something like 177mm x 99mm when I measured it.

Either way, the hole in my fascia would only fit the smaller units, and this is definitely not one of those.

Where these two "standards" actually apply, I don't know, I thought maybe the US had the larger standard, so these units would fit fine, but I guess not from the complaints in this thread.
[Android Head-Units] amc_oldsarge:
What kind of car do you have? Go to this link and see what it recommends.

http://www.metraonline.com/

You need a double-DIN kit, but as this unit is lager than the kit was designed for you will have to trim the hole to make it larger. I used a SHARP utility knife scoring the new cut lines from the BACKSIDE of the kit. Take your time, it took me about 15 scores to pierce through, but it looks clean (like it did originally).

---------- Post added at 12:22 PM ---------- Previous post was at 12:15 PM ----------

Does anyone have any ideas for addressing this?

Has anyone tried this with success (or failure)?
[Android Head-Units] mcsvt:
I would be interested in trying that version also.
[Android Head-Units] :
i measured 17.7x10.2cm in my car.

I hoped i could buy anywhere such a frame and didn't have to cut my frame....
[Android Head-Units] amc_oldsarge:
Afraid your going to have to cut. Not a big deal, just take your time.
[Android Head-Units] fcortes626:
my unit should be here sometime this week. its already in LA but idk how fast dhl delivers. also ordered my backup camera and i found someone who sells the double din kit for my car.
[Android Head-Units] donaldta:
I believe that you may have been looking for dash kits for your Honda and got the two "double din" specifications there. As I understand, 180 x 100 mm is the ISO 7736 / DIN 7549 standard for most of the world. Where as, the United States doesn't use the metric system (officially), so our "double din" standard is 7 x 4 inches which converts into 177.8 x 101.6 mm as opposed to the internal standard which would converts to 7.08661x3.93701 inches.

But, if I search the following key words "173mm x 98mm radio" on eBay, I see listing for a lot of faceplate / bezel / dash kits. Many of them with the following warnings.

This leads me to believe that the double din standard describes the installation aperture not necessarily the opening for the console trim.
[Android Head-Units] KID52:
Hmm yes that does sound reasonable.

It does get a bit confusing, I think there as you say the actual ISO standard is for the internal part of the radio (that connects to the cage/rails inside the dash), which I haven't heard anyone having an issue with.

It's the part that goes through the actual hole in the dash/fascia that people have an issue with, and that there are two "standard" sizes for.

These AN-21 U units (I think like a lot of other Chinese units) basically have the front flush with the internal part, whereas if you take a look at many other "name brand" units, you will see they have a step down to the smaller "standard", like in the picture below.

Given the issues that seem to have been experienced recently with MCU changes, I'm not going to be the one to find out :D
[Android Head-Units] KID52:
DHL took 3 days from China to UK for me :)
[Android Head-Units] donaldta:
Here is an example listing which fits with my theory.
[Android Head-Units] KID52:
Yes, I assume we are both using "internal" to refer to the normally metal part of the unit, and the external to mean the front plastic part right?
[Android Head-Units] E350:
NFC Capable?

Will this headunit itself, or is there a dongle or other device or software, which will allow this headunit to use NFC (near field communication)?

I would like to use a NFC disc with it to launch applications
[Android Head-Units] KID52:
Not built in, but there does appear to be USB ones available.

Something like this.

http://www.partshe.com/jt502-usb-nfc-tag-ic-card-reader-for-android-ipad.html

Although I think for that one you need to write your own software (maybe it works with existing software too). I'm sure there are others around that already have software though.
[Android Head-Units] donaldta:
Well, if you think of it as pegs and holes. I think the actual standard describes the the "hole" not the "peg". The metal part of this "peg" comes in different sizes. In fact, most third-party radios will come with its own cage to adapt the size when the radio is smaller than the actual standard.

As for the opening for the external plasic console / facadia / bezel / trim / dash kit / etc... yes, that is a different specification, at best maybe the new "de facto standard". I wouldn't necessarily call it a standard though, unless an official standards organization body declares it.

[Android Head-Units] PsychoMcSatan:
If we're talking about iGo on this unit, or Android in general, then you might want to check out this guy's Youtube video:

http://www.youtube.com/watch?v=WLR_dkI7cc0

Not sure of the copyrightiness of it, but he links to a copy of 9.6.29.346622 which is nice because it integrates Google search and also supports 800X480 (his link also has very fast downloads). He only includes Brazil maps and Portuguese voices, but others can be pulled from older versions. You'll need to use Google translate to understand install instructions, but it's pretty straightforward.

He also has a Loquendo APK that apparently gets the TTS voices to work (which you also need to find elsewhere for english), but it didn't work for me. However, at that point I also discovered that my regular voices had stopped working as well (they worked fine before I started fiddling with TTS). I checked Sygic, and that too was now doing stuttering.

After some uninstalling and reinstalling, I've gotten Sygic voices to work again, but it's got me thinking that this Brazillian guy's version may have hope for TTS voices. However, my unit is installed in a car in a very cold Canadian garage so I'm probably not going to give it another go this weekend.

I think the difficulty with TTS in iGo and Android is that Android has its own TTS engine. Once I installed the Brazillian's Loquendo TTS, I was able to choose it under Android settings under "Language and Input". Just too many different setting permutations to know what messed it up and what might be needed to get it working.

For now I'm happy with Sygic, though I think iGo does handle on the fly POI searches much better, especially how this newest version has Google search integrated without being tied to Google Maps' bandwidth-hungry mapping.
[Android Head-Units] KID52:
I tried very hard to get TTS to work as I liked the feature when using Google Maps, and the occasional mispronunciation was amusing, plus in the latest version the voice is actually half decent, the original one a few years ago was terribly robotic. However, despite my efforts, and multiple different versions of TTS engines I gave up and settled for the standard "turn left/right" narrations, but the sound is good quality.

Recently I did find a few places where the TTS system really fails (using Google Maps). Travelling along the motorway the voice started telling me to turn off, and proceeded to read the entire list of roads that this turning lead to, meaning it went on for around 15 seconds or so, but by this time I had already taken the turning and was needing the next instruction, however it insisted on finishing what it started.

Does Sygic have free live traffic? I think that was one of the main reasons I went for iGO, plus the Google search is useful, but seems a bit unreliable, often saying "Unable to connect to server" despite having a perfectly stable internet connection (minimizing iGO and opening browser confirms this too).

The version I have is also 800x480, looks great on the screen in the car, display is quite large and easy to see from just glancing rather than actually having to look properly.

The speed warning is also useful when I'm unsure what speed the road is - it's great having speed camera signs everywhere, but what speed is the damn road!? It seems to think 73mph on the speedo is genuinely 71mph, I don't believe the speedo is really that accurate...
[Android Head-Units] fcortes626:
hopefully it gets here early tomorrow so i can install it lol
