I played the stereo test program that test both channels so I think that means both left and right are working. I didn't hear that the radio could crash my system. Could you specify what happens with that or link me to it please? This system over all is EXTREMELY buggy so I wouldn't be surprised about anything crashing this system. I'm still looking for a navigation app that works properly on it. What really suck is that this came in the worse possible time because I really have 0 hours I can devote to testing this because I just found out i was moving at the end of this month about 4 days ago.

Looks like just a sheet metal screw that would be extraordinarily bad at self tapping :P. Take it with you to a hardware store and ask an attendant to help you match the threads.

The serrations on the face just give some added friction so that it can't work it's way out. If you can't get those, it doesn't matter too much, either ask someone to recommend you a different lock washer arrangement, or just put some loc-tite/CA (superglue) on it before assembly. Personally if it was me I would match the threads and the approximate length, ignore the point and get whatever is available (that point doesn't look like it would do anything anyway), ignore the head unless you need to turn it from the side and just get whatever is available that you can turn, and ignore the serrations and just put a dab of loctite/CA on it.

That instability sounds pretty bad. Is it ruining the whole thing for you?
[Android Head-Units] Drakey83:
Thanks for the advice I'll give it a shot.

I honestly think most of the problems that I am finding seem to be glitchy software issues that seem similar to some of what I read about on the AN-21 U thread. I'll give you some examples: First my unit came with iGO, it didn't come with any North American maps but I was fine with that because I had already bought a legit version of Sygic and just planned on using that. I installed Sygic and it tracks fine (if not slower than most nav apps I've seen) when cruising around but when you actually put in an address to navigate too then the program intermittently looses sync with the GPS signal to the point where it is just unusable. So then I install Waze to see if that'll work any better with the GPS signal but I cant even run that program because it cant find my SD card. So I try MapFactor which Finds my SD card, seems to lock onto my GPS signal while navigating because the tracking seems very fast and fluid, but I am unable to see anything on the map other than the route I'm on and then nothing but just solid green. Finally I just downloaded the most up to date USA maps I could find for iGO just to see how that would work. Well I got that to work and the GPS lock was GREAT but I couldn't hear the voices from the navigation software. Oddly enough at this point I felt pretty relieved just knowing that everything wrong with this unit just seemed to be software related and not hardware. So I then did a system restore just to start over. I already had iGo installed on my SD card so I just re installed that and crazily enough, after that, everything seems to now be working (as far as navigation apps are concerned).

I am alot more happy with this product now knowing that everything seems to be working hardware wise and its just really badly programmed on the software side. I know software can get better over time and I probably will be able to get it working pretty close to how I want it as soon as this month is over and I have some free time on my hands. Right now it just really sucks wanting to try to mess with my nav system and knowing I just have no time to do it.

This is definitely NOT a plug and play unit, to get this to work the way you want to is going to require alot of work on the owners side.
[Android Head-Units] Nereth1:
I wander how long until it get's better though :( I'm not sure how long this kind of thing takes.
[Android Head-Units] saidak:
Thanks for the update Drakey!

I can tell you that non of the Chinese HU are ever just plug and play, I have had a few and all the good ones need a lot of hard work to make them work as the "owner" wants them.

Good luck with your move and hope to see more pictures, videos, thoughts and reviews of the unit. and note the more people get to know about the HU, the more they buy the more the evolutionary trend of development and improvement happens.
[Android Head-Units] Orisai:
Let's hope we can crack the bootloader as someone did with the HuiFei unit. That opens a whole lots of new possibilities, specially custom roms.

Being based on the same Exynos that powered the Galaxy S III, there are lots of information and source code around the Web that could help any interested developer work to improve the unit.
[Android Head-Units] Drakey83:
That would be AMAZING! This unit has great hardware and would be awesome with good software. I need to stop talking crap about this unit so people will actually buy it and we can get a community going.
[Android Head-Units] Orisai:
The next step would be to fully decode the MCU protocols used by the stock apps, so we can create or even develop a custom ROM with better Radio, iPod, and Bluetooth apps.

I hope one day we see an AOSP-based ROM like CyanogenMod running on these stereos.

Can someone confirm if this unit has an external mic input?
[Android Head-Units] saidak:
Try the following steps:

•Go to Settings → More → About Device

•Scroll down to Build Number

•Tap it repeatedly (It'll show a message telling you how many more times you need to tap it to enable developer mode).

•See the Developer options menu under Settings → More

I know this works for Android 4.3!
[Android Head-Units] Orisai:
I can confirm this also works on Android 4.2.2, as I had to enable USB debugging to root my canadian SGS4.
[Android Head-Units] hella356:
Anyone know what the RCA output voltage to external amplifiers is? Any provisions for subwoofer control or crossover (HPF/LPF) functions? Also, is there any analog input, either RCA or 3.5mm?
[Android Head-Units] toologic:
I have wonderful news. The seller sent the device for me. I'm waiting to receive the parcel after 15 days. I will give a full report carefully.
[Android Head-Units] Orisai:
You'll most likely need a line driver with these units.

http://www.sonicelectronix.com/cat_i697_line-drivers.html
[Android Head-Units] hella356:
I assume since they don't list the specs that it's probably 2V, minimal subwoofer controls, & no crossover. That's a pity, as it would add additional cost & complexity to my rig. My aging Eclipse AVN5435 outputs 5V, I could probably get away with it if it did 4V. I'll email them for the spec.
[Android Head-Units] chris.davis925:
Please let me know what you find on the voltage preamp output levels as well as how much control for crossovers/equalization is present for the rca ports.
[Android Head-Units] hella356:
As soon as I get a response, I'll post it. If these audio-related specs fit the bill, I'll take a serious look at purchasing.

First public firmware for this unit: http://wd.coldzone.ru/upload/firmware/8935更新软件.rar

...

Android 4.2.2 devices are NOT samsung exynos, but 2 core telechips
[Android Head-Units] hella356:
So, you're saying the earlier versions have the quad-core Exynos, but the newer revisions have downgraded chips? Bummer. Might still be sufficient for car use, but more power is always good, especially when battery life isn't an issue, like in the case of a car stereo.
[Android Head-Units] nE0sIghT:
Yes.

[MENTION=546466]Drakey83[/MENTION]

Can you confirm it? How much RAM in your unit?

---------- Post added at 10:37 PM ---------- Previous post was at 09:50 PM ----------

One russian owner of this "new" revision unit confirmed that it is "ARM Cortex A9, dual core 850 MHz with 789 MB RAM"
[Android Head-Units] hella356:
Man, that IS a downgrade. Scratch this one off my list....
[Android Head-Units] Drakey83:
Yeah, I just checked. I'm FURIOUS! I'm disputing my order for false advertising and asking for $150 off my order. I already have the unit in my car so I'm not sending it back. I just want him to give me $150 off my order and then just never even think of using aliexpress.com ever again! So do they just not even make the quad core units anymore or did they just send me the wrong unit?

Also do you know what this new update does and how to start the update process?
[Android Head-Units] nE0sIghT:
Unpack firmware to sdcard. Hold back button while powering HU on
[Android Head-Units] Drakey83:
doesn't seem to work for me, it just restarts the unit with no update.
[Android Head-Units] chipped:
WTF so these are not Quad A15's? Daaaaaaaaaam!!!!!!!
[Android Head-Units] nE0sIghT:
From russian owner:

1. Unpack firmware to SD card

2. Plug in SD card to left slot

3. Power up device and hold Back button while Logo shown

[Android Head-Units] Drakey83:
I wish I could go back into time and slap February 3rd Drakey83 in the face!

Ive tried everything and nothing works for me, maybe its because I have the universal unit. Are you getting this unit still [MENTION=5702785]nE0sIghT[/MENTION] or did you just get a refund?
[Android Head-Units] nE0sIghT:
I'm in exchange process now. After (and if) i receive this new unit i will sell it
[Android Head-Units] Drakey83:
Well, I am really mad that I was lied to but I already put $100 into getting my unit installed so I don't want to lose out on that money. Plus it seems to run all the programs that I want it to right now so I guess I am going to keep mine.
[Android Head-Units] chipped:
Sigh... I've given up on this one.

*puts on **** list*
[Android Head-Units] typos1:
And me, thats a MASSIVE downgrade.

Its between the AN21-U and the Huifei unit for me now : http://xdaforums.com/showthread.php?t=2660662

The Huifei guys have already unlocked the bootloader and there are so many other devices with those Rockchip processors out there (such as Andorid TV boxes/sticks) with loads of existing hacks and mods (such as running full desktop Ubuntu !) already available seems like its the best and most versatile option.
[Android Head-Units] toologic:
I got HU, but Chuck send me Telechips 893x (2 core) 1Gb android 4.2.2 and NOT worked touch (bottom part screen) instead Exynos 4412 (4 core) 2Gb + 8Gb

I feel for you. Same thing happened to me. Sorry buddy.
[Android Head-Units] Zaphod-Beeblebrox:

Have you checked/confirmed that the unit even has the 1024*600 display?

[Android Head-Units] Zaphod-Beeblebrox:
Now that you've had a little more time to spend with it, how is the overall unit working? Is it quick & responsive enough?

Lockups, instability, etc?
[Android Head-Units] Drakey83:
It seems to work good enough, still haven't messed with it alot. Copilot was the only navigation software I found that works well with it but luckily it's only $10 and works perfectly. Other than that it seems fast enough but its pretty unstable and acts weird (torque pro disconnects randomly) but it's mostly useable.
[Android Head-Units] hella356:
Still haven't gotten an email response from them...
[Android Head-Units] Zaphod-Beeblebrox:
And it looks like interest in this unit has all but died now :)
[Android Head-Units] Drakey83:
Not a suprise with a bait and switch product like this.
[Android Head-Units] Zaphod-Beeblebrox:
Wel, I finally broke down and ordered an AN-21U variant this morning. I was really wanting a 1024x600 Hui-Fei unit, but I also want one with a volume knob, but no DVD. Actually the faceplate/housing of the one you have Drakey83 is exactly what I wanted.

Couldn't find a Hui-Fei unit meeting those specs, but I did find an AN-21U that did (800x480 screen though, not 1024).

I've also seen where the Hui-Fei users have made a lot of progress with recovery and root, but modifying system APK's is leading to bootloops. I want to be able to make some quick hacks to SystemUI, so I'm taking my chances with the AN-21U.

Welcome. I also have such a device for 3 weeks. Android 4.2.2. There are problems. Wifi is very weak. I sit in the car under their home and get on my wifi router netgear.With me phone htc one.

[Android Head-Units] Drakey83:
No clue how to fix the weak wifi as I have the same problem. The gps not showing the speed however was fixed by simply using Co Pilot as my navigation software. This shows my speed correctly and it works as a navigation program perfectly.
[Android Head-Units] moro2008:
Thanks for the tip. CoPilot really shows speed. But I have 7 years of use the program Navitel. Any idea how to make a show of speed in this program?

The AN 21-U is a pretty well known entity now, and we all know what a dud the WD8801 turned out to be :) (Sorry Drakey :))
[Android Head-Units] typos1:
Its not as well known as the HuiFei, seeing as the Rockchip processor it uses is much more widely known and used than the MStar one the AN21U has, still, like I say its too late now.

[Android Head-Units] Soul0Reaper:
So just to be clear, is there a head unit that has an exynos? Or is it just one seller misrepresenting their product.
[Android Head-Units] Zaphod-Beeblebrox:
I don't think it was so much mis-representation as it was a design change that wasn't communicated back to buyers.

The first couple of units mentioned by people in this thread were indeed Exynos based, but had a lot of issues. You'll then see that the 'second round' of buyers were delayed in getting their units. Likely due to the re-design.

So, to answer your question, I don't believe there is a unit currently available that has an exynos chip.
[Android Head-Units] Soul0Reaper:
Ah darn, do you know of an Android head unit that has some more grunt behind it and (preferably :P) 720p or higher res?
[Android Head-Units] Zaphod-Beeblebrox:
The most popular unit by far is the AN-21U :

http://xdaforums.com/showthread.php?t=2660662

There have been a few listings for both of these units claiming to be 1024 x 600, but I'm not sure if any turned out to be true or not.

Once the WD8801 proved to be a dud, I ended up buying an AN-21U variant. Has plenty of power for what I use it for. I use Poweramp primarily to play music stored on a 32GB Sd card. I use Waze and/or Co-Pilot for nav and everything is plenty responsive.

I also have one of the older 'Ouku' units (single core 1ghz, Android 2.3 and a resistive screen). Now that one was slow and unresponsive.
[Android Head-Units] Soul0Reaper:
Yeah I know those two but I'm looking for something that has more power behind it and some better screen res. Looking around it seems there are non, guess I'll settle for mirrorlink

[MENTION=5702785]nE0sIghT[/MENTION], I see your still talking about this unit in the Russian website and I see it looks like there could possibly be a firmware upgrade. I don't want to try to upgrade until I can get a confirmation that this update will work on this HU without it bricking it and I don't trust Google translation enough to determine whether or not the upgrade is safe and what it might fix. As someone who understands could you please fill me in with the latest details about this units please?
[Android Head-Units] nE0sIghT:
I received new unit from seller recently and it is an-21 u. I do not know about any firmware update from zhinavi for exynos wd8801. All known owners of wd8801 (exynos version) in Russia are selling it or exhanging to another unit

Hi .

Please help With whether change.

I want to change wallpaper for radio and i dont Know how.

I want to change apps post on first page but ... ?

And to use bluethoot Thorpe.

Please help if you make this.

Thanks.
[Android Head-Units] toologic:
1. Wallpaper is integrated into Radio-app (LuyuanRadioSet.apk). If you want change it, you must search on this site as to do it. SORRY. This application use common (launcher) wallpaper.

2. Apps on first (default) screen of launcher is a predefined and you can not change it.

3. I did some changes into Settings.apk (turn on Bluetooth settings, Developer Settings, Account Settings, Location, Security, Memory Info)

Please test on your devices.

Install sequence (use ES File Explorer):

- check, that Root features is on, and R/W options is on for "/", "system" partitions

- rename /system/app/Settings.apk to ....Settings.apk.orig

- copy my unpacked Settings.apk into /system/app/

- close ES File Explorer

- open terminal (i use Android Terminal Emulator)

- switch to root mode (type command "su")

- reboot device (type "reboot")

PS. Some words about root-ing device. Our device (remind TCC8935+android 4.2.2) already have root (su, busybox apps), but its 'soft'. To correct it, you must download SuperSu app from market, run it and update su by "normal" way.

I actually went through this and the other thread being talked about (all 150something pages of it) and it seams that most people that bought the other (older) unit were happy with it! Yes the guy did disappear for a while and then when he came back he was not answering all the "support" questions that were asked but one must remember 1) those guys are sales people, and 2) it could be that it is not the same person and indeed the account is a company account not a personal one!

having said that, it does seem that semting and VWcars are the same person and which does bring a ? mark to the situation.

all and all I am tempted to say it is not a scam but the advert needs to be treated with caution!

Whooh and I thought I was the only one like that, get/buy them, play with them, brick them then regret playing with them!!!

I did see that a few people from Denmark, Spain and Russia bought those units. unfortunately the units is too new for any to put a review/feedback also pity aliexpress does not allow direct contact with buyers, would have emailed them asking for feedback.

I guess will have to wait and see, maybe by next month if no feedback then I would bite the bullet and get one [although with my current finances, I need to win a small lottery to do that :(]
