Selling one of these

Hi.

I'm selling my one of these units as I just changed car and the new one is a fully integrated job. It's one from eBay and exactly like the one on this thread's front page. It has everything these comes with such as manual, remote (still sealed in bag), all wiring, and the original box. It has both the WiFi AND 3G dongles included plus I upgraded the SD card to a 32Gb version (still has iGo on it) which I am including too.

It is working perfectly, has no marks, scratches or cracks, and had been rooted but I factory reset it to sell.

I have also wired it up to a standard ISO socket via a terminal block (check photos) as these units come with bare wiring. This means you can either plug it straight in to an ISO harness or easily disconnect the block if you want to wire it yourself.

PM if you are interested. UK only.

Very Low Mic Volume

Hi All

Is there a fix for very low microphone pickup?

There is an external and an internal microphone. The sound is very very low. Is there a setting we can change etc?

Hi there,

Is this unit also a AN-21 U ??

http://www.aliexpress.com/item/Andr...assat-Polo-Bora-Jetta-Touran/32219633187.html
[Android Head-Units] kaween:
Yes. (based on hardwarespecs-MS Cedric3 platform, and typical UI).

[MENTION=4423880]ryrager[/MENTION]

No. There's no software setting to influence the Mic sensitivity. The internal is ... crap (in my case at least). The external mic that came with my unit works adequatly : it doesn't pick up the noise of the car, but I do need to speak up a bit (don't have to shout, but I do need to raise my voice a bit) to ensure perfect understanding "on the other side", but not any more than I have to do in my wife's car which has a handsfree system factory installed.

So far for what I know. Now for a bit of speculation on my part :

Did you make your own mod for external mic, or was it prepared for external mic ? Becuase ...... actually, the AN21-u hardware does not support a "either" solution : I've got several guides to adding external mic's to the AN21's, and even the official version does NOT permit to have BOTH internal and external mic connected. When the external mic port is implemented, the internal mic must be detached PERMENANTLY from the circuit by the modifier OR the modifier must use a switch in the connector for the external mic that disables the internal mic from the circuit when the external mic is connected. The AN21 board does not have that logic onboard, meaning that in such cases, the external mic cable should have at least 3 cables (mic signal, groud, switch). If your cable has only two wires .... something's fishy.

If you're saying your unit lets you use internal AND external mic, chances are it has been modded in a not-so-clean manner, meaning BOTH mics are connected at THE SAME TIME to the BT's mic input port : this causes all kinds of not-so-nice behavior (wrong impedance value and thus bad signal response, interference of both mics on each other ....).
[Android Head-Units] 3Shirts:
Oh. I've taken it out of the car now so it's a bit late for that :(. It definitely does boot and works fine though. I will guarantee it, free return postage if not!
[Android Head-Units] anpo:
If it's for handsfree phone calls and not Android voice guidance I would recommend something like a Parrot mki9000. That's what I did, you need a double mic and noice cancellation DSP in a car imho.

How can you random all files and folders on a USB or microSD with the default player?

I can random play the songs in a folder, but not random all songs in all the folders.

How is this done? (Installed Neutron Music player of now)

2nd problem.

When I place the Neutron Music Player widget on the main screen, this functions well.

But when I power off the unit and power it on again, the widget is gone.

Shortcuts stay on the mainscreen on the place where I placed them.

Power amp ?.

I hate all the default players.

Power amp for music, mxplayer for videos.

Other than those 2 apps my radio is practically worthless.

Need latest Firmware with full apps included

Hi all, hope someone can help

I recently installed a new firmware in an attempt to fix a r/o issue with my internal SD on my AN21U. I am still getting issues with the unauthorised UI and my head unit is still showing my internal SD as R/O, also the apps are not the latest version. Could someone please give me the links to the latest version of the firmware that includes all the apps etc for this head unit? Also I need the patch to remove the UI warning.

Anyone else experienced the R/O issue on their internal SD storage? Any ideas how to format it and start again?

Hi All,

Hoping you all can help me out. I just installed a an-21u unit in my wife's car with a backup c amera. i confirmed that when switched in reverse the camera comes on. I've also confirmed that the video wire run to the stereo works by setting up a aux monitor on the stereo end. Video comes on every time i switch to reverse. The problem is that i connect the rca cable to the camera in and the screen does not auto switch to reverse image when i put the car in reverse. This happened out of the box with my other stereo...

I tried switching it to F Camera, and the pic came through on the stereo while in aux mode when i put the car in reverse, though the camera in seems to do nothing... is there a setting i'm missing? Please don't tell me my wire harness for the stereo is bad.

If you can please provide me with some things i can try to get the stereo to switch screen mode when kicked in revers it would be appreciated. This is the last piece of the installation that i'm toiling with and i want to finish it up.

Thanks in advance!

Hi All,

So i purchased a AN-21u for my wife's car. I also got a parrot mic off amazon that worked perfectly on my stereo in my car. After installing everything including the mic, just as i was buttoning everying back up i realized that this harness is missing the MIC connector.

(lower right side)

this was the pic on the auction which would have worked and is exactly what i had in my car (the big white plug with the 1/8" headphone style jack), though sadly the mic plugin is missing.

I'm hitting up the seller now to see if he'll send me a replacement harness, but i'm assuming this is not going to work out. I'm currently evaulating other options. Anyone know of somebody that is selling this harness with the MIC attachment? I'd be willing to even trade my own plus $ for the swap. I really need this connection.

Please let me know!

No problems with the install.

The launcher looks ugly.

However, 90% of times when booting my unit used to freeze for about 5 minutes and then come good. Touch wood, this firmware seems to have fixed the problem, fully opens 100% now. :good:

Is there any way to change the launcher icons? I don't want to use a launcher.apk as the ones I have tried don't allow me to move the menu bar from the right side.

Some questions

Hi there,

I just bought a similar unit, which I think is the same one with a different front face. You can see the item here: goo.gl/7qJiO0

I searched a lot in this thread but I can't find a good answer, I'm wondering about the Bluetooth pairing with Torque.

It seems that the Bluetooth is restricted to some kind of devices (phone, ...) which make it difficult to pair with Torque. Did anyone find a solution to that? Is rooting helping? Or is the best way to use a Bluetooth Dongle?

According to the seller, the system version is 2.8.6. Is it good? Last version is 2.8.8. Should I update?

Is it easy to update the Android 4.2? Does it worth it?

Thanks a lot for your help!

Thanks a lot for your answer. When you say "forget about OBD-BT", I'm wondering if it would still be possible to use a Bluetooth USB Dongle? I have three of them so I'm pretty confident one of them would work. Or is it dangerous to break something else, like internal bluetooth?
[Android Head-Units] kaween:
No. Unless the BT module you'd be testing is really defective and in short-circuit, there's no hardware risk in trying that.

Actually, it would be pretty interesting to hear if and what usb BT would be recognized by a stock AN21.-U and to be honest, the chances of it working is pretty slim. Even if so, you'd probably need a third party BT-connection manager to make such a setup work and force the connection between OBD and USB BT. (look at the old Ouku XDA threads for more info, the extra usb-BT module was the trick they used there to hook up the Ouku with an OBD-BT)

But that shouldn't hold you back trying, and I'm rooting for you.

Here.com ?

No problem.

By the way, in terms of free and legal navi software, take a look at Nokia's "Here" beta for Android. Feels a bit like Google Maps, but more up-to-date from a pure technical point of view. Not without issues (beta and all) no doubt, I Did a quick testrun on my phone with it today and I was impressed. Tried it on the AN21, it does boot and offers off-line maps in a really usable manner, haven't done a real route with it though.

Well worth checking out I think. Can't be found on Playstore, but it offers to download itself when you surf to here.com using Chrome.
[Android Head-Units] tututut:
Hi all of you,

I'm new here (have been lurking in this thread and other ones as well for a while though) now I have an AN-21 as well and some issues with it.

1) An issue already discussed: Third party audio doesn't work for me neither. That is majorly annoying since third party audio was the main reason for me to get an android car navigation system.

It does work after opening/pausing/closing the stock mp3 app. I have been trying to automate this process using Tasker but have been unsuccessful so far.

Did anyone have more luck with this? Is this an issue that applies to all AN-21U devices or just to some? Any firmware fixes etc.?

2) (How) can I access external micro sd cards with the installed file explorer/what is the path?

thanks in advance, tututut :)
[Android Head-Units] kaween:
Greetings and welcome ! :)

1) Which 3th party software refuses to give you audio ? By switching the sound priority settings to "3th party", you should get sound out of them no matter what. In some players (like Poweramp) there's an internal "sound priority" setting too for these kinds of cases when everything else fails, but the system-wide priority settings should solve this issue pretty well.

2) Honestly, just install Total Commander or Root Explorer, and you'll never have any issues like that anymore. And when you root the device, it will play nice and allow you to do all the "nutty stuff" which the stock File explorer misserably fails at. The standard File Explorer is pretty much useless in my opinion compared to the two I mentioned before.

Check the broad flex cable between mainboard and screen assembly. I've had comparable bad behaviour on a unit because of a bad connection there.

Unlock the Flex retainers, take out the flex and check the silver-coloured contacts on both sides : see if they're straight, re-align them if need be. Re-insert the flex on the mainboard and Screen assembly.

If the problem remains identical, do a 180° swap of the flex (connecting the side that was inserted on the mainboard side to the LCD connector and vice-versa).

If the problem disappears, great.

If "a new problem" appears (other colors missing, other effects) : your flex is bad and needs replacement.

If the problem remains identical : either the LCD control board or the LCD itself is defective. Slightly press on the LCD control board : if the problem changes or disappears, the lcd control processor has developed a cold joint and needs reflow. If no change : LCD defective.

What you have there is NO software issue and can not be solved by a software update.

Hello my friend. We miss everyone, as true geeks should stick together no matter where they are posted on this earth of ours. :)

Can you reinstall an mcu when things to sideways ? Yes.

Is it possible to brick the unit using a very bad MCU or wrong mcu so it becomes nearly unsalvable ? Yes.

As long as the hardware code is correct and you don't try flashing an MCU from a totally different unit (for example flashing the MCU file from a RK-based device), you should not be able to brick your unit.

But I still say that unless you've got something that is "broken" with your current mcu, I'd advise not to thinker with it.

And if you do, double check the HW codes of your existing MCU version, make sure you have access to EXACTLY that original version before playing with this stuff, and make sure you choose an MCU with the same HW codes as your existing one.

Failure to do so may end up in all kinds of hurt. :)

Hi all... I just bought a Ouku 7" 4.1 radio and I'm trying to get it to work a bit better.

The music player doesn't show the songs on the SD card, it shows the folders then the songs. So I can't have it play all the songs on the card, just the ones in a folder. Sucks. I was trying to find another player that works right but I can't find one that will find the SD card. They only find the songs in the internal memory.

I connected the CAN wire (car) to the CAN RX on the radio but it's not doing anything.

These seem to be buggy systems. Are there any fixes or better SW/FW? I've already rooted it. System 2.7.9 MCU 4.3.1-1-10-0901 The place said it was 4.2 but the radio says 4.1
