If you do, please tell us your experience with it - I'm considering doing the same with my unit.

Although I'm a bit worried about the big heat sink case. I wonder how hot it will get with the current draw, when the radio is running and using the built-in amplifier.

Also since it must be connected on the permanent power line in my case, the bias current draw should be very low, so my car battery will not drain.

Thanks again. I used that crazy Russian Baidu Root 2.4.6 from this thread and got it to work perfectly! Now I can change my boot animation!!! (and yes, that's all I ever wanted to do with it)

I am editing the wiki with this update so people don't keep getting confused and asking. My apologies for not searching harder.

I installed SuperSU from the play store and it seems to work just right. https://play.google.com/store/apps/details?id=eu.chainfire.supersu&hl=en It'll say that it needs to update something on first launch. Make sure you have an internet connection, it should just do its thing, and then use the 'Normal' method of access when that prompt comes up.

addition to the Pico system.

You don't need a big battery if your primary concern is to bridge the crank gap. An AN21 with a pico-ups and a smal 2.1 Ah battery (approx 8x1x4 cm) will provide power for approx 20 minutes which should be more than sufficient.

Another bonus of this solution is it does not need extra cooling as long as you don't draw more than 6A from it (it stays absolutly cool when it has to power the AN only, without any extra cooling), and as stated it does not put a load on your battery when your car isn't running, as it decouples its charge function from you electric system as soon as the input voltage drops below 13.5V so no risk of a drained main battery .

Starting 6A and up however the pico ups needs extra cooling so if you hook it up to extra loads (added amp, active sub, stuff like that) you will loose the bonus of not having to worry about cooling.

Also : on several cars, it's not JUST the voltage drop of the crank you have to worry about. It's not uncommon the ignition key mechanism itself will decouple all non-essential electric loads from the ACC to allow maximum power for the crank. In such cases, a stabilizer won't cut it, as during crank on such cars, "there is really no power". Like, Zero. :)

The only real downside is it is "another battery" that can go bad after a given time. Mine is running for 2 years now by the way.

So you might consider putting it in a location that is servicable or at least accessible without having to tear down the complete dash. ;)

But yes, I'd like to know if that stabilizer can do the trick too as it is a more elegant solution sizewise, and if the cars with "full decouple" of the loads during crank can be helped by this .... because I would be surprised if it would.

This is oddly specific and I imagine it is probably part of the MCU as a video overlay, but for CAN users with the provided decoder box, when you open a door or your trunk, it shows an image of a vehicle and exactly which door is open. Anyone know if it is possible to change these images? I would prefer just an outline vehicle and not a half-realistic picture of a car that looks like a 1990's Oldsmobile station wagon.

Also, my steering wheel controls include a "Mode" or input button that pressing repeatedly cycles through all available media sources on this unit (Including Disc, which mine does not have) and I would never use the functions that it cycles through except Navigation and maybe AUX or Radio. Does anyone know if there is a way to change what apps run using this button? it would be nice to be able to assign what apps it cycles through. I would ideally just make it open my app drawer, but CAN buttons can't be re-assigned :(

That's indeed totally unacceptable. Sorry to hear that.

So far I've been lucky with most of the sellers I used. Last one somehow was able to send me a unit without the cables (... seriously, no system power cable). He asked me to send him a picture "of the missing item" (euh ?) but it all was resolved very quickly : After he understood the absurdity of his question, he send me the missing cable using a high-speed courrier without any charges. So yes, there are sellers out that who're a bit more honest in their dealings with customers.

Hmm. Providing you haven't messed up the wiring (is it a new installation or did it used to work correctly at a certain point in time) and didn't mess with the balance/fader ect ect, I'd first try to reset the unit (does wonders sometimes). If that doesn't change anything, try hooking up 2 testspeakers to the front outputs and see what happens. If nothing comes out, try the "cinch" variation. Check if your cable is seated correctly in the unit itself.

If all that fails, you MIGHT have a defective amp chip .... but that's pretty rare these days.

Bought A New Generic Radio but i have some issues

Hi there, I recently procured a new android AN-21 U based smart stereo, I have a few questions, hopefully one of you might be able to help,

1.Firstly I would like to use XBMC as my default "media hub" as in to play all my music,dvd's,cd's,videos,and streaming content, and maybe also integrating the radio tuner function.navigation in there as well.

*So to start implementing this I tried to find the mount point that the pre-shipped apps(which are completely horrible BTW) use when their buttons are pressed Ie the point at which the instructions from the mcu gets integrated with android, But I could not find any of their mounting points.

* Then i thought it might be in a system folder only view able by a superuser, so I tried rooting it, but i used the chinese baidu root app and i accidentally picked the wrong option when it installed thereby rendering my su access useless since no other su app gets granted the necessary privileges,then I tried resetting the radio and that didn't work (in fact made it worse) since that su app is now corrupted and i cant remove it without root access and i cant just re install it since the radio doesn't allow replacing installed apps without removing them first.

2.I also cant install any of the new updated firmware it just fails, the only one that worked was the format one, but that also did'nt clean out the stupid corrupted su app.

Can anyone advise me on what to do?

for some reason asians are asking for pictures

I had bought the android radio from ebay not know what a mission it would be to navigate and update, fix physical error on it. I wanted to return it for full refund. She wouldnt respond back. So I opened a case with ebay and they forced her to accept my returned and refund my money. I was happy but then ebay sends me a message stating that in order to get the full refund, I have to pay for shipping (which was free). I am like fine so annoying but fine. I went to the usps and dhgate, and fedex webpages and it cost 60 to 150 dollars am like WHAT THE ****? So I kept it gave the lady negative feed back and now I am here searching through threads to fix my radio....but she did ask me to take a picture of the unit to make sure that the screen looks HD....Am like WHAT?lol thats just dumb. I can take a picture of the radio and screen photo shop the picture by replacing the HD screen is a pixelated screen and she wouldnt know the dif. its dumb

---------- Post added at 06:28 PM ---------- Previous post was at 05:48 PM ----------

-----well Before i installed AN21U I had the stock dodge radio. It all worked fine.

-----Then I installed IN THE REAR ONLY 2 new Kenwood (KEN-KFC6994PS) 6 x 9 Inches 5-Way Car Speakers and they worked very well and still do. But I didnt notice if the fronts were working because I never gave it a second thought.

----So I bought received and installed my AN21U to my car and when I installed the rear speakers worked fine (not noticing the front speakers)

-----Then I decided to replace all the stock speakers so I replaced me stock 3.5" speakers on the windshield with Kenwood (KFC-835C) 40-Watt 3.5-Inch Round Speakers

----That was when I notice something is wrong I turned on the radio and the back ones worked but not those and I checked the front and didnt work either.

---- So I saw a video on you-tube on how to check if a speaker functions properly using that POP! method and all the speakers POP!

- ---I also check my car electrical diagram to make sure the positive is in the positive and negative it in the negative and it was.

----I decided to install all of them except for the front left 6x9 speaker how it hasn't been touched and assumed its the radio and will try to resolve it another time (which is now).

----Now I will check the wiring again from the speakers and radio but I dont think its that but maybe am wrong. have you experianced other people with this? :(

Hello everyone.

I bought this unit recently. I have one problem with Sygic . I installed the app and downloaded the maps and it was working perfectly, but suddenly it gives me the error : " Access denied to sd card" and the app is not opening. I dont know why this happens if the app is installed in the internal memory of the unit...

The unit has the 2.7.31 version. Should I upgrade to 2.7.42 and root it? I have realised that system is not allowing me to erase the files that are placed in /sdcard. But Im afraid to upgrading and getting more errors... is the 2.7.42 stable?

Thanks in advance
[Android Head-Units] kaween:
Look at answer #1914. http://xdaforums.com/showthread.php?p=49994022&highlight=sygic#post49994022 concerning the Sygic question. As for upgrading : is there an immideate problem or thing that doesn't work ? Ask yourself why you'd want to upgrade it, is there a specific reason or is it "just to upgrade for the sake of the upgrade".

As said, you're the only one who can answer that question. If the unit works correctly and you've no open issues or wishes, I would _not_ upgrade it. If you want to toy around with it and test all kinds of new stuff .... you wouldn't have asked this and you'd already have rooted it long ago. :angel:

Changing car model under extra settings

Anyone know how to enable this kind of function. Is it under extra settings because under there there is several car models. For example Hyundai IX35(4.3.8.1,AD,Config,TDA7719,Tef662X) or IX45(4.3.8.1,AD,Config,TDA7719,Tef662X) would fit me. I have Kia Sorrento 2014 2.2CRDi and basically it is same as Hyundai Santa Fe. If i try can it be reset to as it was. Also in the rear at the multi connector at back and there is cables stating CAN_RXD and CAN_TXT (steering wheel controls are presumed to be working thru CAN?).

Running original Android 4.2.2, MCU 4.3.8.1-3-10-040201 System v. 2.7.39. Cannot get the picture smaller but you can see the connections clearly

Hey guys,

short question from my side: Anyone using Google Speach aka "OK Google"? I keep installing the Google Now app which also automatically installs this Microphone App linking directly to speach input (aka if I would say "Ok Google") and it works great. Problem is everytime the device restarts the Google Now App is still there, but the speach functionality as well as the "speach app" is gone. Anyone having the same issues? How to fix?

Bests!
[Android Head-Units] gyaku_setsu:
Functions like this aren't enabled or disabled. If you have a CAN enabled vehicle, anything that can normally be sent to your factory radio will show up on this as a video overlay from the MCU.

Here are the functions that CAN vehicles do automatically and cannot be disabled or enabled except via the vehicle's features:

Steering Wheel Controls (buttons are pre-programmed and cannot be re-assigned)

Door Open Indicator (Displays an image of the vehicle and which door(s) are open as well as the trunk/hatch)

Reverse Image (if no camera is detected, it displays parking sensor information. If neither is present, you get a blank screen when reverse mode is detected. To prohibit this, disconnect the reverse wire from your CAN decoder to the radio).

HVAC Changes (If you have computer controlled climate control, the display will show changes made to it)

Music Information Relay to Dash Computer (If you have an on-board computer in your instrument cluster, the unit will send current playing song information to it if you are using a factory default media app)

You just have to be sure the correct vehicle mode is enabled and/or available. My unit was made to fit the hole of a VW, so that was the only option and it works flawlessly with the above list of functions (except one of my steering wheel buttons that I never used anyway).

Give up

Google now does not work on this unit. I have tried everything and keep experiencing the issues you are describing as well as others.The only way I was able to get it to work semi-consistently was to install ADW launcher which has a little microphone icon on the screen. Pushing the iicon takes you to the google now page and automatically makes it start listening. After giving it a command though, the sound gets all messed up. and the only way to fix is to restart. I dont want to get into more detail, but there was a lot more i tried. After months of trying I gave up. Sorry... But its not going to happen with this unit.

That is bad news ... What a pitty. Thanks anyway!
[Android Head-Units] storm83:
Thank you! I appreciate the extended explanation of this. It's nice to know I have more than one option to tackle this issue. I was just imagining that it would probably be a larger battery, but that clears it up. As far as the ACC goes.. I'm not entirely sure if it matters all that much if it loses power or not. Since the deck is in a sort if "stand by" mode... it is suppose to resume after the ACC has been cut off anyways. It does it all the time when I turn the key back to on (without engine crank). So I am assuming one would really just have to worry about the constant power and the voltage drop that occurs when cranking the engine.

WiFi

Hey guys,

Sorry to bug you again with another question from my side. I tried an 3G USB stick before which wasn't working. Therefore I bought a Mobile Wireless Hotspot device (MiFi) from Huawei together with an 3GB contract. The MiFi is working great e.g. with my smartphone, but fails to work with my car radio. The WiFi connection itself works but it seems I don't get to have any internet connection...

Here it becomes strange. I tried to make a portable hotspot with my HTC One and my iPhone. Every time the same issue, the WiFi connection itself gets established but I don't get internet. Strange thing #2: my WiFi from home works like a charm with my car radio!!!

Could it be that the car radio is just working with fix internet routers but not with WiFi hotspots? If so, how can I fix it?!

This is the last piece to happiness, please guys ;)
[Android Head-Units] kaween:
WHOT ? YOU DARE TO BUG US ? :) And I was just having a beauty-nap. :D

I can tell you your issue is not typicall for the AN21. I use my lowcost Star 9589 phone as Android AP with my unit, and it works flawless. (3G + mode).

I've done the same thing with a low cost Alcatel Idol Touch that supports LTE, and that too works very, very fast.

It is an odd problem and in truth, I'd probably start with resetting the unit and see if it makes any difference. Try and see if the leel of wifi security has any influence on your problem (no security, wep, wpa2 .... i'd try them all).

Maybe an odd question, but just for the sake of test, have you tried to connect your Iphone to the HTC when it runs as AP ? Just to make sure that functionality is okay ? What USB WIFI stick are you using ?

Hey,

thanks for your quick answer, hope you can help. So here it is what I narrowed it down too:

Car Radio -> Home Wifi (WPA/WPA2 PSK) = works perfectly

Car Radio -> HTC One (WPA2(AES)) = connects to Wifi network but no Internet (e.g. Spotify, Play Store, Browser, ...)

Car Radio -> iPhone 5S (WPA2 PSK) = does not connect to Wifi therefore also no Internet

Car Radio -> Sim Valey USB 3G Dongle = does not get recognized at all

Car Radio -> Huawei E5330 mobile / portable Hotspot (WPA2 PSK) [klick for description] = connects to Wifi network but no Internet (e.g. Spotify, Play Store, Browser however works once in a wild but super slow?!)

HTC One, iPhone -> Home Wifi = works flawlessly

HTC One -> iPhone 5S Hotspot = flawslessly

iPhone 5S -> HTC One Hotspot = flawlessly

First thought, could it be that the unit has problems with WPA2? Will try to change it on one of the devices, but not sure if I actually can do that .... Additional thoughts welcomed.
[Android Head-Units] gyaku_setsu:
I am also running a mobile Hot-spot in my vehicle, but it is 4G (because 3G is outdated in a major US city), and have had no problems with my unit connecting to it every time—even with the provided generic WiFi dongle. I did get the Hot-spot from my mobile provider and it is designed for vehicles. Look up a Delphi Connect OBD2 dongle + 4G. They're pretty sweet ;)

Maybe try one of the other WiFi dongles from the wiki or maybe try a different mobile Hot-spot? The generic WiFi dongle that comes with it is known to be dodgy and WiFi hotspots can be hit or miss from my experience.

I have it installed in a 2009 VW JETTA and get all of this functionality. Maybe since the manufacturer makes VW specific units, they're better at coding this functionality. Maybe your car doesn't support displaying those things on the radio from the factory. I know my factory radio did, so there are protocols in the CAN network for these functions.

No boot up animation. Just hiss from the radio.

I have tried installing firmware but as the screen is black nothing happens.
