I don't think you bricked it, just a matter of how to flash the firmware files. I read that B.Stromberg was having the same boot loop issue after factory reset like you in post #2100. Maybe you can message him and ask him how he flashed his firmware files, given that you both have the same unit.
[Android Head-Units] kamold:
Ok I did a factory reset and the system is functioning normally now.

However the reset removed apps including the play store etc.

I installed play store apk 4.8.19 however it crashes...

Can anyone let me know what version of play store works properly on this system?

Thanks again
[Android Head-Units] Kn0ck0ff:
If anybody is put in this situation were your stuck in a boot loop after a factory reset after upgrading FW , do a 2.6.60 update from start up screen , its puts the unit back to life :)

---------- Post added at 03:01 PM ---------- Previous post was at 02:37 PM ----------

Hey buddy i noticed this too aswell , it was hit & miss with system resets , sometimes play store would be there other times it wouldnt , try one last factory reset , thats what i did to get play store back anyway , the apk i downloaded also crashed all the tim .

Hope this helps

I just got this one (it came from China & I am in the U.S.) I ordered May 9 and got it on May 15.

http://www.amazon.com/dp/B00HM89P18/ref=pe_385040_30332200_TE_item

CMOS is crap!!! Definitely go with CCD. MUCH better image (and low lux sensitivity) for just a few more dollars. This one cost me $23US and took only minutes to install. It claims to be HD but imo if it uses a composite cable it cannot be HD, but the image is very nice. I work with cameras (i build red light cameras & mobile & fixed speed cameras for a living) so I am somewhat judgemental to image quality.

Effective Pixels : 680X582/628X512 (NTSC/PAL)

Resolution : 480TV lines

Definitely NOT HD!!!

Check the companys website (I wish I did) before you purchase, Mine came in chrome, but you can get it in black & they have some other cool stuff (like many chinese suppliers do lol)

I had to remove my trunk lid liner (1999 Infiniti) The hole was already there above the license plate, just made it fatter. Connected the red/black to the left reverse light power source. Ran the cable thru the car & connected the yellow rca to "camera" and the red wire to the brown (reverse) wire. Im happy. It looks great. Oh yeah, to answer your other question, I think they ALL come mirrored if the are advertised as a "backup camera" or "reverse camera"
[Android Head-Units] Merc1032:
The chineese do have a lot of cool gizmos..and usually they are cheap enough you dont feel to bad when they crap out, lol.

I have seen the listings go both ways some mention them as mirrored image some dont, some I think you can even swap two wires around and change it up. Its really pretty minor..I have backed up for years knowing how to use mirrors and the truck has back up sensors already, its more or less a "hey the headunit has the option and the camera is only 20 something bucks" kind of thing.

My truck (08 F150) does have a factory cam option and it mounts the camera in the tailgate handle. It looks cool but for what ford (or hell even the aftermarket) wants for just the empty handle with the hole to mount a keyhole camera is like half of what I paid for the headunit, lol.

Im probably going to go with a license plate frame style one, this way If i ever remove the tailgate I dont have to worry about wires and loose functionality.

Thanks for the tip on CCD cams tho, didnt know they were pretty much as cheap as the CMOS ones.

Cant wait for my headunit to arrive on tuesday!!

PS- So your the guy that makes the cameras that takes the nice pics of my cars going through the toll booths! :D
[Android Head-Units] MFKinSINY:
Indeed they do, and I have a workbench full of crap that proves it can go either way. Ancient proverb: You generally get what you pay for. Which is why I buy the most expensive toilet paper hahaha.

You're welcome, but they aren't "as cheap" it's just a closing gap in price difference over the years due to manufacturing technologies & I happened to score on this one. They usually aren't this cheap. Seek & you shall find! and YES that is me. Toll booths, railroad crossings, school zones & over 8,000 intersections in the US. Drive carefully my friend :) and good luck with the HU.

[Android Head-Units] Blaylock1988:
I am considering purchasing a factory fit one for my MK6 GTI with the larger 8" screen that has the knobs up top. Does anyone have this version? I need to make sure it has red backlit buttons.

I messaged a seller here: m.aliexpress.com/item/1860560870.html?tracelog=wwwdetail2mobilesitedetail and they said,

"Dear, this unit didn't have red led buttons.

We have them in stock, and we would shipped it right now.

Thank you.

B.R

Annie"

Does that mean it has no backlight buttons at all or are they some other color and not adjustable?
[Android Head-Units] chanh55:
Only Black Screen...

So I updated the firmware to 2.6.70 to get Google Play Store which my unit didn't come with. Everything was working perfectly fine for about a day. Then 1 day when I started the car for work, it started making weird static on the screen. So I turned off the car and back on to reboot it. Then the static got worst, so I reboot it again. Now it doesn't boot at all and turns on to a lit black screen. All the buttons light up and the fan turns on, so I know it's powering on, just not booting.

I tried hard resetting and all that... nothing seems to make it want to respond.

Any advice on how to get this thing to boot?
[Android Head-Units] Blaylock1988:
The seller just responded to me, they said it has red backlit buttons!

They have responded to me 3 times in the past couple hours, i'm impressed. I think I am going to pull the trigger on this one.

Update:

Payment sent and the seller said they have it in stock so should be shipped in a couple days! When I get it I am going to put it on my bench and root it and do the works to it before putting it in the car.

Great work chris.r.r. - sure beats the tacky skin that came with the stereo. Unfortunately I'm having a few problems getting Apex launcher to keep the car launcher pro widget after reboot. I'm really tearing my hair out - was up until the early hours and I'm supposed to be doing loads of DIY around the house on the first day of my week off - wife will kill me!! I prefer ADW launcher but I couldn't get it to stay as default after reboot despite converting it to a system app with Titanium Backup Pro (thus worked for Apex launcher). Any help greatly appreciated. Thanks

Hi, I have purchased tablet talk from the play store, and I've installed it on my LG g2 phone. The latest version is 1.9.9.2

I cannot install it through google play on my AN-21 U because it says that this device is not supported.

I searched and didn't find the apk on my phone so the only choice was to download an oldest version and side install it.

How can I install the latest tablet talk app on my car stereo?

Hey kamold,

I am having the same problem and symptoms when rooting my system. I updated to 2.7.9 from 2.6.70 and applied the newest MCU (4.2.13-7-10-6501). All was running well, except the knobs were behaving backwards. (Turn clockwise for decreasing values, counter-cw for increasing values.) This has something to do with the MCU, but shouldn't have cause issue when rooting.

I have followed the instructions, but after the first reboot I have black icons and a slow system. I run step 2, reboot, and still have a slow system, black icons, and can't 'su' in Terminal. (Permission denied) I've done a factory reset for now, but would like to get root working. Were you ever able to get it to work on your system? How are you going about rebooting your unit? I was just holding the power button until it fully turned off. (~10 seconds)

Thanks
[Android Head-Units] Kn0ck0ff:
Hey guys i had this numerous times during the rooting process of my an-21 u , i found that the only way to get it back normal was to do a system reset from settings screen , it can be done , if you swipe from bottom to top & vice versa while away from your home/widget screen , you get colour back tempolarly , look at were the 7890 are & reset the unit that way .

Also what i found when this black affect was occuring is that there were files still there from my previous root on previous FW , once old files were deleted , the root went pretty smoothly.

When your getting "access denied" to the "su" input on android terminal , it means its not seeing super user , download & install super user before rooting , this should solve your issues

hope this helps
[Android Head-Units] KID52:
When I updated my unit and tried to root it I also experienced this permission denied error when typing "su". I think something must have changed in the newer versions of the firmware to alter the rooting process (needing to install super user beforehand).

My new unit has now arrived so when I get a chance I will update the instructions and try to figure out which firmware version requires which set of instructions.

How to delete system apk file

Does anybody know how to delete system apps (apk) files , iv got one last idea on this live wallpaper issue iv been having , im going to try & delete , the custom wallpapers & the live wall paper app , plus all the existing origanal live wallpapers , then install audio glow , see how that pans out .

I cant believe nobody else is having this problem , or so few should i say lol

Heres a link to whats actually happening , its very strange indeed !!!!

https://www.youtube.com/watch?v=I3I2gjmGBuc
[Android Head-Units] KID52:
You just need to root the unit and use a file browser.
[Android Head-Units] Kn0ck0ff:
The unit is rooted & i have es file explorer , but i cant seem to get that deep into the files , havent seen a system folder anywere .
[Android Head-Units] KID52:
You need one that allows you to browse as root, not sure if ES allows that.

Poweramp has a setting called "Folders and files" where you can check what to include in your playlist. See it Poweramp sees the ipod directory and them to your playlist.

I can tell you for sure that from 2.6.96 and above I have always had to install Superuser and update the binaries beforehand so that I don't get the permission denied message after su.
[Android Head-Units] MFKinSINY:
I use ES file explorer & I am able to get root access with it. It may be a setting in the app. I can check later, but then again so can you.

I also use root explorer. Does the job equally as well.
[Android Head-Units] KID52:
I am not in a position to check as my new unit is sat in a box at my house 100 miles away. However, I am sure the original poster of the question can have a look in the settings of ES File Explorer, or use a different app.
[Android Head-Units] jpapadami:
I also use ES File Explorer and I love it. Under Tools there is a button to turn ON Root Explorer. Also clicking on Root Explorer opens up a dialog to Mount R/W so that you can edit the system directory.

The fact that we can use the faceplate mic to do google searches should've proven this theory to be incorrect, no? Has anyone tried alsa to change the sensitivity of the mic? I might give both of these a shot after work tomorrow. Too busy to play today. If anyone has experimented within these two avenues and has had some real effect (positive or negative) please post about it thanks.

Is there anyway to get my youtube app to display as it does on my android tablet? Meaning when in landscape mode, I can still see comments and video info on the side, subscribe button, etc...with the option to make it fullscreen.. Instead of just being a fullscreen video all of the time?

I searched and downloaded an apk that was supposed to be from/for a tablet... but once ibgot it installed it looked and behaved the same as on my phone.
[Android Head-Units] digitaldr:
I got the 2 knob version last week and am trying to get all my tweaking done before installing it. So far I've managed to root it and will be adding an external mic in the next couple of days.

I hate the stock apps and their homes screen icons and have been trying to replace them with the custom ones from the skinning section of the wiki. Try as I might I have not been able to get the car widget pro widget to stay on the home screen after reboot. It disappears every time with all the launchers I've tried. I'm running the latest firmware but haven't updated the MCU. If I did update to the latest MCU would this solve my disappearing widget problem? (I suspect it wouldn't!). I would be a bit nervous that I might loose the ability to reverse the knobs as I have a right hand drive car. Speaking of which is there any easy way to make the system apps a little more right hand friendly eg radio presets on the right.
[Android Head-Units] sciallo:
I have installed alsa and played with the sensitivity briefly. Not in depth enough and noth through the BT phone yet. Unfortunately (well, or I should say fortunately, responsible adult I am) I got really busy and will have to experiment more...

At first impression I can say that it does make a difference but I don't think it's in a good way, it seemed like it would kick it up too much and distort.

As I said just preliminary impression, take it with a grain of salt. I do encourage testing and reporting here :)

I have the same problem with the connection widget for tablet talk. My first suspition with that, audio glow live wallpaper and other widgets that don't survive reboot is that they might somehow rely on external storage that isn't yet mounted when the launcher comes up. (Just an unconfirmed theory)

Install market helper (not from playstore) and you'll be able to see it and get it (and other apps you wouldn't be able to). Sideloading might not work because of playstore license check...

Kn0ck0ff,

That was exactly what I needed. I didn't have superuser installed before running the root application. Once I reset and installed it first, the root process worked beautifully.

I was also able to reverse the direction on my knobs in the 'Extra Settings' menu.

Many Thanks
[Android Head-Units] digitaldr:
By external storage do you mean the SD card? I'm pretty sure I didn't see anything new written to it after installing car widget pro unless it's trying and failing to write to it at boot up. I'm going to pm Chris.r.r and ask him how he got it to work.
[Android Head-Units] chan.jmc:
What binaries?

Please excuse my noobness, what do you mean update binaries? I've been having the same problem as Kamold described, I tried what KID52 suggested, installing Superuser before rooting and I'm following the instructions to the dot... but my unit still crawls both after Step 1 and Step 2 and I'm getting the permission denied thing when i try 'su' in terminal emulator app.

Anybody know what I'm doing wrong?

edit ---- I worked out what I was doing wrong. And i worked out what binaries were!

I had been installing the chainfire superuser app, which wasn't installing binaries for some reason. So i tried the clockworkmod superuser app and the prompt came up straight away for me to install binaries. The rest of the root process went smoothly and I now have a rooted unit :)

[Android Head-Units] Kn0ck0ff:
This happened to my first unit , i got an advanced replacement & had to send the other one back , you shouldnt be asking for a new motherboard , you should be asking for a new unit all together , you will void your warrenty installing a new mother board & do you have the correct knowledge to do so .

[Android Head-Units] chanh55:
Good point about voiding the warranty... I'll make sure to bring it up to the seller. And yes I'm very comfortable doing this stuff. If you open the top and take a look at the board, it's a really straight forward design. All the screws and stuff are visible.

Who was your seller that was nice enough to send you an advanced unit?

[Android Head-Units] djblaze852002:
Installation Questions

I assume the AN-21 U comes with a parking brake wire. I am wondering if you know of a bypass method for this wire? Also what does the wire limit? Does it only limit the playback of DVDs only when in park? Or does it limit other functions too?

Also, does the GPS antenna have to be in the window? I am considering just putting it on my dash... I am trying to make the install as easy as possible without having to pull wires everywhere....

I am still waiting to hear about my order. I am confident that it will be fine.. I am used to delays and inexplicable things when ordering direct from China. But so far have never had an item not come...
[Android Head-Units] KID52:
It does come with such a wire, but it's no problem to bypass. Just don't connect it to anything (or connect it, it makes no difference actually), and disable the check in the menu. It's literally just an option that you can choose to have or not. I think it only disables video playback, not sure if that includes video files or just DVD.

GPS antenna does not have to be on the window, mine is in the dash too, worked perfectly so far. Just make sure it has a good line of sight to the sky, and not too much material between it and the sky, mine simply has a thin piece of plastic covering it.
[Android Head-Units] disc golfing:
Is it possible to connect a front camera/dvr to this unit? I know you can connect the rear camera to it.

I know the S100 is capable to have the front camer/dvr option, but I can't find any info on this one.
[Android Head-Units] KID52:
It's got two AUX ins, so it's definitely possible to connect a camera and view the feed in the AUX app.

However it doesn't come with any software for recording as far as I know, and I don't know if Android can "see" the AUX in video feed to record it.

I'll have a word with Peter when I next see him online.

hi guys, just ordered this one from Alliexpress:

http://www.aliexpress.com/item/Capa...ore-2-Din-Car-PC-head-Deck-DVD/929502900.html

I prefer the two knobs as I think one can be used to scroll through folders (which I have over hundred on my music USB).

The hardware seems to be exactly as the one listed by few ppl in this thread. The seller ships with DHL so with a bit of luck, I will get it before Xmas. I'll post impressions and photos / video once I get it.
[Android Head-Units] disc golfing:
Thanks, that would be great!

I haven't seen him on here since you started this thread, but I'll catch up to him one day....lol I know with the time difference it's kinda tough (I'm in Eastern US).

I believe some of the cameras had the dvr in them but now I can't seem to find them, except for the one on one of the Ali sites, but it's for the S100 and possibly the S150. I've been using the AutoGuard Blackbox app from the play store on my S3, which saves the recordings to the card, it can be set to save on the internal or external. So if a front camera can be connected to run with that app, and save it to the SD, then that would be wonderful. But as you mentioned, running it through the AUX probably isn't possible.
[Android Head-Units] KID52:
He is online now :)

Unfortunately it does not appear to be possible, Android does not have access to the AUX inputs, so no way to record on the unit.

But if you are going to be buying a front camera, why not buy a DVR anyway?

Edit: I do not think he visits the forum much, but he is on Skype.
