what do you guys think of this unit:

http://www.aliexpress.com/store/pro...h-dvd-3G-WiFi-function/925772_1189469443.html

in comparison to this one:

http://www.aliexpress.com/item/New-...D-GPS-Navigation-System-Video/1517513062.html

pros? cons?

scratch the above. realized the removable unit is only a 1ghz single core with 512k ram. Cool as it may be to have a tablet/car stereo hybrid, 1/2 the power is a dealbreaker for me.
[Android Head-Units] guano30:
Yes i think same!

Does [MENTION=1915855]KID52[/MENTION] maybe have contact to the devs of this Unit?

As i look at Google i found several Threads about Samsung S2 with low Mic.

Switching off the Noise reduction helped there....

But we circle, coz nobody knows how to enter Service Menu of this HU or else..... Even now no Key Combination to enter Bootloader.....
[Android Head-Units] donaldta:
No, LOL. Poking the mic will only ruin its fidelity. It won't remove the impedance from the circuit. You'd have to physically remove it to reduce the impedance.

What is the error message? If the toast message that is displaying the error is too quick for you, then you can use "adb shell" or a terminal app to install the APK. Using the command "pm install {apk.name}" will allow you to read the error message at your luxury. You can even encapsulate this with logcat in order to get the output specific to the problem, "logcat -c; pm install {apk.name}; logcat -df /mnt/sdcard/installerror-logcat.txt".

Complete garbage. Check these Youtube videos; KL3vBZb0qDM and qIELIgr2d9g.

The specifications suggest that is an AN-21U. The only difference is that it has a custom faceplace that is normally associated with certain Nissan vehicles.

So i have an update ... He now claims another resolution -> 1024*600

That is very similar to 800*480, but is it actually "better" in everyday use? Does anyone have a unit with this resolution?

QUESTION

ANSWER

Either he does not understand or does not WANT to understand my question, but I guess that unit is "as good" as any other unit, but it is cheaper at the moment. I think I will try it ... What do you think [MENTION=4927791]p64imp[/MENTION]

[Android Head-Units] ecoast:
ery good.

just for the record; I'm goiing on unit # 3

first was $200 CE model; seller claimed wifi-- there was none- ebay return; made them pay return ship- yallstore

#2- $299--unit in this thread; fooled with it a bit; lost Sygic capabilities- 'SD Card Access Denied" , rooted; could not fix-- return shipping again being paid--newdealstore2012

#3 $299---just showed up (2 days China to East Coast!!!) --will report back later after I install and note any differences with it -- superseller4399

hint to buyers: if using PP, switch source of payment to your credit card.

Offers another layer of protection as most CC co's will stand behind your dispute on a internet purchase...fwiw

lastly...any way to wipe #2 unit above so all my user info can be deleted?

device is rooted...
[Android Head-Units] donaldta:
Bingo! You finally asked the correct question. The larger resolution means it will use more memory for the display and you'll end up with smaller icons and fonts. You can try offset the screen density to make items to appear larger but it will use even more memory to display the items.

The advertisement of the larger resolution is sketchy at best. They either know what it is and can prove it or they can't. At this point, it is pretty obvious he doesn't know wtf he's talking about.

Btw, this was kinda dumb.

The vast amount of information within the app would require hundreds of screenshots in order to capture it all. Just ask him (or the manufacturer) to email you the output of the file when exporting the system info. Unless they edit the file to spoof the information, it will give you the exact screen resolution along with all the other specifications relative to the unit that you want to know.
[Android Head-Units] p64imp:
Hi all,

To your experience, do all these units support large hard drives? I've seen multiple sellers claim the units only support 32gb usb sticks (including the seller i purchased my unit from), though i've seen some of you talking about plugging in as large as 1tb hard drive.

Item i ordered: http://www.aliexpress.com/snapshot/6012810476.html

If anyone has personal experience, can you advise on the following:

1. does it matter which usb port you utilize? Are the ports on the front and back different in terms of device support?

2. what is the max usb space you found it to support?

3. is there file structure limitations? i.e max # of folders, max filename length? what format does it support/or is it limited to (fat32,ntfs,etc)?

Thanks much!
[Android Head-Units] donaldta:
I posted most of the answers to your questions in another thread, so I'll forgive you for not using the "Search This Thread" tool. Although, the SD card question was answered in Post #1406 of this thread.

btw in most cases, you can reformat SDXC cards with FAT32 in order to be supported by the Linux vfat drivers.
[Android Head-Units] p64imp:
Apologies and thanks. I'll have a look.

So if i format the usb hard drive to FAT32 then i should be able to get around the specified 32gb limitation and without any software modding on my head unit support a max of 1tb? 2tb? are there # of folder limitations like on some units? I know my wife's head unit buggs out when the # of folders exceeds 255. This creates issues when i try to pop in my music album collection.

Also, do any of these units support US digital waves? Seller i'm talking to claims there is no such thing as an ATSC tuner for these units. If i found a tuner somewhere else, would i be able to install it myself? Anyone know where i could get one that works with my unit? http://www.aliexpress.com/snapshot/6012810476.html

I know another user said he's going to try this:

http://www.newegg.com/Product/Produ...yMark=False&IsFeedbackTab=true#scrollFullInfo

but i didnt see an update, and i'd have no idea what app would even begin to make use of such a thing. This wouldnt be the only option for the US would it?

Thanks.
[Android Head-Units] fcortes626:
try downloading terminal emulator from the playstore and run :

su
wipe all

i think thats what i ran last time to do a factory reset when my unit was messed up. or try using the factory reset in settings.

By the way Playerpro music player worked with the folder mount app. It pretty cool because it has a built in equalizer and the UI is nice. the next, pause, and previous buttons are not small like in other players. im thinking of doing the same thing with foldermount to get sygic maps into an external sdcard.
[Android Head-Units] guano30:
Okay...

To Solve the low Mic Problem I just bought a Preamp.... Hope it will be delivered fast.

I hope it brings me there where I want to. It has Adjustable In and Output so hopefully it works....

I think waiting for a Firmware Solution could be a Waste of time.....

Next Importance now should be to find a Solution for the BT Phone App and its Contact Management.

Hope that can be replaced soon!

I really want to talk to that DEV who build that App. No Search, no VIP Dial, no Nothing.

I also tried to use the Contact List of Touchstone. But if i try to call a Contact its not working coz its not linked to that silly BT Phone App.

Jesus, i really wish i would have some more Experiences in Programming those Apps....... :(

Why these Chinese Trolls cut all off that Android System? Would also be very nice to use a BT Keyboard to make Shell more easy.
[Android Head-Units] chris.r.r:
Bluetooth app is kinda crappy, but it offers at least search functionality:

Long press on the top left button in the phonebook page opens up the searchbox...
[Android Head-Units] ackyo:
really... awsome!!! i was thinking the one thing this app needs is a search function then i could live with its crappiness

:D

on the mic question, i have the VW version of this unit and the mic seems to be working fine - everyone I have talked to so far on the car kit seems to be able to hear me clearly (right hand drive car and mic is on the left of the unit)
[Android Head-Units] jakejm79:
From what I understand, have been told ATSC signals aren't well received in a moving vehicle so no one makes that as an option.
[Android Head-Units] guano30:
Aha....

You try finding something else than a Phone there? For example a BT Keyboard?

With my HU no chance to pair anything else than a Phone

That Mic Thing kills me!

I hope this has nothing to do with the different Firmwares. I have the latest xx.70 installed.....
[Android Head-Units] donaldta:
The 32GB limitation is not for USB Hard Drives. It is for the SD "Cards & slot". I supposed this wasn't made clear in my previous posts. The SD(HC) Cards that are 32GB and lower come pre-formatted with FAT32 which is compatible with the Linux vfat drivers. The SD(XC) Cards that are over 32GB are pre-formatted with exFAT which is not compatible with the Linux vfat drivers. In most cases, you can replace the exFat partition with a FAT32 partition to allow the larger cards to be compatible.

As for the USB Hard drives, the FAT32 partition has a theoretical limit of 8 terabytes, maximum file size of 4 gigabytes, and a maximum of 65535 files per directory. Microsoft put a limitation on it in their drive tools to 32GB to sway people to NTFS. So, if you have Windows then you'll need to use a third-party drive utility to partition disks larger than that. Whereas, the Linux vfat drivers can support a FAT32 partition up to 2 terabytes and a maximum file size of 2 gigabytes.

You're probably referring to the garbage indexing on some of the older Kenwood, JVC and Clarion head units. Honestly, I do not know if the stock media players have this limitation since the head unit has an 8-bit MPU. There hasn't been any complaints so far, so I doubt it. If it does then you can just use a third-party media player to bypass the limitation if it does exists.

I take it you mean [MENTION=304291]Black6spdZ[/MENTION] from Post #1124?

I doubt it would work since there doesn't seem to be any drivers or software on the Android side of the head unit to support it. The DVB-T and ISDB-T modules the reseller/manufacturer are referring to would be soldered onto the MCU logic board NOT connected via USB. Most of the digital TV support for Android seem to be focused on DVB-T.

That's something that they HAD to do to offer speakerphone access and phonebook sync for mobile phones since it being paired as a Bluetooth client. The only company whose head unit gets this right is Parrot. However, they're using a custom CK5050 Bluetooth module that they created for the Asteroid range.

Besides, there's nothing stopping you from using a USB keyboard (wired or wireless) with it.
[Android Head-Units] donaldta:
Btw, this was recently announced by Geniatech, TV Tuner for Android Phone/Pad. No clue if it actually works though.
[Android Head-Units] Drakey83:
So I went ahead and ordered the "WD8801" unit that sciallo talks about in the wiki as having untested specs. It seems like I'm the only one dumb enough to take the gamble. Anyways, I don't know when I'll get it and it probably won't even be shipped out until mid February because of the Chinese New Years. If your interested in hearing more about my experiences with it, even the shipping process, I'll be updated my progress at http://xdaforums.com/showthread.php?t=2618348. I'll probably make a new thread once I get it so that I can post first impressions, pictures, movies, etc., so they will all be in the same thread. Feel free to follow my progress if you are curious or interested.

P.s. here is the unit I got http://m.aliexpress.com/item/1549098207.html?tracelog=wwwdetail2mobilesitedetail , I had 2 seller competing to get me to buy it from them so I managed to get it for only $480, free shipping, and a 32 gb SD card thrown in for good measure.
[Android Head-Units] donaldta:
How about verifying up the information before arbitrarily pointing fingers? The Wiki history suggests that [MENTION=3081576]sciallo[/MENTION] added the "WD8801" syntax after the 33311 update.

:good: Congrats on the purchase. I look forward to your updates.

[Android Head-Units] voodooless:
I've been looking at one of these Android car stereo for some time now, thingking the one this thread is about, is the best option.

So yesterday, I came across a new model, claiming to have a Quad Core Equinox CPU and 2GB of RAM. You can find it at aliexpress by searching for 1549098207.

They have lots of screenshots. It looks quite nice and has a 1024x600 screen! Has anyone seen this one yet?

Post #1834
[Android Head-Units] typos1:
Nor are DVB-T signals - I ve tried a car specific DVB-T tuner in my car and an Android TV box with a DVB-T tuner.

With both, when driving the signal keeps dropping, it comes and goes (I only tried the radio when moving, not the TV, but thats likely to be the same or worse).

I have 2 boosted antennae connected to the single antenna socket.

I would be interested to hear if anyone has one of these units with the built in digital tv (in any format, pretty sure they all have only 1 antenna socket) and how they perform when moving - do you get signal drop out ?

You can buy micro usb DVB-T tuners for Android and doing this would probably be best as I think these units like Donaldta says, have the TV tuner connected to the MCU rather than Android.

Some of the more expensive TV tuners for cars have 2 antennae sockets, this is called "diversity" and should eliminate signal drop out when moving. But I ve not seen any diversity TV tuners in any digital TV format for Android though.

I m sure I have seen ATSC boxes for car use, I m also sure I ve seen some of these stereos with ATSC as an option as well - I googled "android atsc" and there are some available, including the Geniatec one that Donaldta mentioned earlier.
[Android Head-Units] guano30:
btw.

does anybody know where is the original source of Firmware of Manufactor?

First i thought its a TH8581GA HU.... but as i google i only find that with android 2.xxxx

Its silly, coz all look same from the Outside.....
[Android Head-Units] donaldta:
Nope. It is not available. Before you say, "its open source, so they have to release it". That's not true since Android is released under the Apache Software License 2.0 which means they do not have to release it.

However, the Linux kernel is licensed under GNU General Public License v2.0 so as long as they do not modify the underlying software then it can remain "closed source". Here's an article, "Why Google chose the Apache Software License over GPLv2 for Android", explaining the reasoning behind the license selection.

They all look the same because each manufacturer sources the "enclosure" from the same place. Then at their facilities, they pair their logic board with the "enclosures". This has been explained a few times in this thread before, and you would have found that quickly had you used the "Search this thread" tool or checking the Generic Head Unit Wiki. You can also find specific information in the Tonghai Create AN-21 U Wiki.

Hello again,

i was looking again at the link:

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

(unit i ordered)

and i noticed something i have not noticed before. Does this unit support 2 micro sd cards or am i mistaken? Look at the top 2 corners of the unit. Is one intended for maps? Very confused now...
[Android Head-Units] Drakey83:
That link points to a camera, not a nav system.
[Android Head-Units] donaldta:
They probably reused the images for the listings that contained dual hybrid Win CE & Android OS'. In these units the GPS is only accessible in WinCE and therefore one slot was dedicated for maps while the other slot was dedicated for media and only accessible through Android. (Or vice versa depending on the board they used or whomever compiled the ROM.

For the AN-21 version, you only have one SD slot available. There is also an internal SD memory built into the unit though.
[Android Head-Units] p64imp:
Thanks for the info.

BTW i edited and updated the link in my orignal post. ;) my mistake...
[Android Head-Units] ecoast:
OK; #3 installed...

ver .70, but with .62 launcher and snow scene screen wallpaper.

many more vehicles listed in 'select mcu'

comes with iGo; not Sygic

one dongle for either 3g/wifi

no mic port

BUT-- SCREEN SEEMS to be RESISTIVE ; not capacitive!!!

grrrrrrr!!! Is there a way to confirm this?

ps- superseller4399 and newdealstore2012 are both Lightinthebox.com !!!
[Android Head-Units] donaldta:
Can you please be more specific?

Does that mean you can either use the dongle

either

3G or Wifi or do you mean one dongle is used for

both

3G and Wifi?
[Android Head-Units] ecoast:
one dongle on rear (as was my #2 unit), so you'd have to use the front usb to do both at same time, I'd assume.

I will get a complete vehicle list....

AFA touch screen; I have to read the description better, I guess...so be careful while ordering---

some say-- 'TFT touch'

what you want will say 'Capacitive Multi-touch'

duh

sendng it back, hopefully #4 is the charm!
[Android Head-Units] donaldta:
Oh, you mean there is only one d

a

ngling USB port in the rear. If that is so, then you can use a USB hub to plug in multiple USB devices. Although, a self-powered hub is recommend as a bus-powered hub with multiple high power devices can sap the electricity from the Universal Serial Bus causing instability problems.
[Android Head-Units] donaldta:
I noticed that the reseller partially updated the listing. Even though it says, "CPU: FREESCALE I.MX535D Cortex A9 1GHz" close to the top and is wrong since the I.MX535D is a single core A8 processor according to Freescale. Lower in the description, it also displays "Main CPU Freescale Corte* A9 i.M *dual core/1GHz" which I supposed could be a Freescale i.MX 6 series.

When you get the unit, can you please run Android System Info and CPU / RAM / DEVICE Identifier to make sure you got an AN-21U and not some new unit which could possibly be the next version of the "Ouku Unbranded". I really wish these dumbassed resellers would post the actual properties of the device instead of randomly putting words in the listing from other advertisements.
[Android Head-Units] p64imp:
I will be sure to do that, yes. I'm hoping to actually receive it in 30 days given the new year. I know alibaba gives you a cutoff to report it not received on day 30, otherwise your ability to file a claim as i believe it is dropped so we'll see...

On a side note, i scoured many listings and it seems that these inconsistencies are a mainstay on that website, so I decided to look past that claim from this seller. He confirmed with me directly that it is a dual core A9, so i'll just have to wait and see what shows up on my doorstep.

In fact even carried over to ebay i saw some listings claiming dvb-t digital tuners support "America" when it should actually say "AmericaS". Big difference. The absence of that one S is going to leave that seller in a world of hurt when people start making their "not as described" claims back to ebay. Shady to say the least.
[Android Head-Units] guano30:
HI Folks!

Another Question...

I still have the Unit in my House testing, so I dont try what happens if I simulate Ignition on or off.

Now by trying this i wonder.

Is it normal that the Stock Music Player dont start where it ends?

Everytime i switch off the Unit / Car i have to go Menu and start the Song i want to hear again?
[Android Head-Units] tarzansg:
It will start from where you left off. Its has a memory that store your last position before unit power off. If you left off while listening to the radio. The unit will start playing radio while you power back on while your Android is still booting up in progress. This i guess made possible by the MCU of the unit, while is non-Android dependable.

I have been following your posting about external mic, which i do faced the same issue. I believed its the Bluetooth app somewhere that we need to tweet to increase the volume of the mic. As i have tested the ext mic with the build in voice recorder, its seem that the playback is loud and clear, so that why i am suspecting the Bluetooth app itself. I am still trying to look for any ways to programmatically tweet the mic vol, perhaps some app in the play store.
[Android Head-Units] guano30:
You are talking about the Music App, right?

If you switch of Car (disconnecting red wire) and switch off again your Mp3 continiue where you left it?

With my Unit not even the Music App is started. It goes back to Home Screen.....

Or can i make settings anywhere about this?

I would prefer using Poweramp, but same Issue
[Android Head-Units] tarzansg:
I am referring to ANY apps, Music player, Radio, DVD, maybe even GPS or BT ap (not tried yet). I am guessing any apps that are build by the MCU of the unit, the MCU will remember the last memory position before you power off the unit, so that it could resume from that position when you power up the unit. you does not need a engine ignition simulation, this is the case even when you testing the unit at home. i have so far never come across anywhere that i could or need to set this, this feature comes as a stock from this unit.
[Android Head-Units] guano30:
Oh sorry, it was my fault....... Ty WWE Smackdown for let me do nothing till last listened Song starts after some time simulating Ignition. ;)

So it lasts some time till it Start where it Ends.

So good that far!

BUT

Its not working with Poweramp.

Only the build in Muscplayer restarts after Off / On........

Any Solutions?
[Android Head-Units] donaldta:
In case it was not made clear, it ONLY works with the stock media players BECAUSE they work with the MCU. Third-party programs that run on Android do not have this capability to restart on their own.
[Android Head-Units] guano30:
but isnt the MCU Mode nothing other than Suspension Mode like at Windows?

Last Position is stored in Memory and loaded back when Unit Restarts....

Jesus, i start to hate this Unit...... Its not really what i aspected about a Linux / Android Device....

I feel back at Apple...... Only able to use what they want us to use......

I hope so much that some guys will "hack" this Unit to make it as useful as it can be.....
[Android Head-Units] donaldta:
No. The MCU is an independant microcontroller unit which handles the low level events that Android does not handle. This includes SWC, Bluetooth pairing, blah blah blah... I said this a thousands times before if you won't take the time to use the search tool then I'm not going to spoon feed you.
[Android Head-Units] guano30:
Ok, ty you help me even you tell it twice or triple already.

Its not easy to search for something if you dont even know for what you should search. I didnt know about that MCU thing and ok, maybe its my fault....

So thank you again for feeding me with your Spoon!

So your opinion is that its in the App after restarting, that the App will continiue?

Or is it maybe in the MCU what Apps will be momoriced and which not?

I have the idea to rename poweramp in system/data with the stock music name.....

but i am honest, i am scared to brick my Unit!
