Please bare with this old and confused man. :)

Can you elaborate exactly what you're trying to do ? Trigger a Pause command in Poweramp prior to shutdown to enforce playback from the same location as when you powered the device off maybe ?

Have not tried it myself on the AN21, but I can trigger a "action prior to shutdown/powerbutton off" using Llama and using the "phone reboot" trigger. I see no reason why the AN21 should not be able to be triggered the same way. Temporary health issues prohibit me to get to the bottom of this, but feel free to report your findings and additional questions if need be.

It depends on the used Wifi adapter.

If you have a pure-ad-hoc thing, it will _not_ work on the AN21. Neither would it work on any other 2din droid unit unless you hack-away-at-it and re-enable ad-hoc operation of the Wifi part of your android unit. I was succesfull in doing that on the S150 using old android 2.1- config files (old wpa-supplicant files ect) : it's a nasty method.

Wifi Adapters that behave like a Wifi AP will work correctly on the An21-U (and any other Android 4.x based unit).

I think I have come up with a solution for the new version of Google Maps always force closing when trying to navigate. I've searched this thread and haven't found one yet.. so I apologize if this is a duplicate. I was playing around trying to get it to work... Just when I was about to give up on it and install version 9.. I decided to try the voice search function...which also caused the app to crash. I then decided to install the "Google" app from the play store. After I installed this.. it no longer crashes while trying to navigate on my radio on the new version of Maps. Hopefully this works for everyone else as well.

Android AutoMate

Can someone please try this app and see how it works? To download you must subscribe to the google plus post and become a tester. Then you can download the app. It looks like it mimics Android Auto. This could really be a nice interface for our head unit ( I am still waiting on my replacement to arrive). Please let me know if anyone has any luck.

Hello friends.

I have not managed to repair the equalizer.

Here I put the video with the problem:

drive.google.com/file/d/0BxDEHQIWcqvea2t0ZTJFX2w5Tm8/view?usp=sharing

And here's a photo of the model car radio:

drive.google.com/file/d/0BxDEHQIWcqveTHBzZFJtMGFocFE/view?usp=sharing

I tried to talk with the seller and there is no way to send me a patch to fix the problem.

MCU version installed: 4.3.2-1-10-6101

Android version: 4.2.2 / 2.8.7_Patched_permroot

Since the update have that problem, I tried to install the previous version and the problem continues. I installed several MCU and unresolved.

See if someone can lend me a hand. Thanks in advance. A greeting.

Hey XDAd,

I have this unit:

Being my impatient self, I started flashing/rooting on what I could find and I believe I flashed the wrong MCU. The headunit's bluetooth is unresponsive (doesn't search devices and is not discoverable, has nothing inputted in the name/pin/code/etc fields) and has no radio reception at all.

Does anyone have the proper MCU file I can update to? I've rooted it so that shouldn't be an issue to be able to flash to an MCU. And can anyone also offer the correct firmware for this?

Thanks,

Justin

Well I got rid of the banner now using the 2.8.8 perm root files. Everything is functional except the bluetooth. Bluetooth was flawless once I updated, but the moment I take the key out and start the car back up (reboot), bluetooth settings go blank and it is undiscoverable/unable to connect again. Everytime I update, it will work for the first time, then will go blank again once I reboot. Any work arounds for this?

Well after doing more in depth research, I found this post:

So after that, my system is rooted on 2.8.8 and everything works except for no radio reception. But thanks to spotify, I will have no problem with that since I rarely listen to radio stations in my car anways.

GROWL Audio MU-X head unit

I have just purchased a Growl Audio Unit (for Isuzu MU-X) and it seems to be a AN-21U head unit (is there any way to make sure?). Here are the specifications:

Cortex A9 - Dual Core ARMv7 MStar Cedric3

graphics - Mali400MP - 800x480 screen

OS - 4.2.2 JellyBean

1 GB of RAM

MCU version 4.3.11-16-10-650101

System version 2.9.3_20150204

DVD version 2.13.13.1-1200xh

Developer code - 7890

However, I was unable to determine the User/Extra codes (I tried '123456' and '7890' and a few other very simple combinations).

: GROWL support provided me with the code '662839', which works for 'Extra', which then allows me to change the boot-logo. They suggested another possible code to try was 668811 (that didn't work).

what I have tested and works so far on my Isuzu MU-X : GPS maps (e.g. "Nokia Here", "Osmand+" and "CoPilot"), radio (FM and AM), media player, steering wheel control (not set-up 'out of the box', but the configuration program in 'Settings' does work), head unit can act as a Bluetooth speaker for my HTC Desire 816 running Android 4.4.2, microSD slots (I am only using one of the two provided), WIFI (better reception than one of tablets), Google Play.

not tested : I have not yet tested telephone Bluetooth functions, or installed the provided reversing camera. I have a USB OBD2 device on order. A DVB-T antenna was provided, but I have left it unattached, as I am not interested!

does not completely work -

: The current boot logo says 'Cadillac', not very suitable for an Isuzu car! 'Baidu Root' is able to gain root access, but I am yet to succeed in setting user/extra options. No Isuzu logos are in /etc/logos (or /etc/logos2).

: The provided wiring harness alters the behaviour of the electricals of my Isuzu MU-X. As soon as the key is in the 'accessory' position, the position/parking lights turn on, and the instrument (e.g. air-conditioning control) lights turn on. The MU-X wiring harness appears to be the same as the Holden Rodeo (and probably the Isuzu D-MAX), in which case the provided converter connects the same red wire to both the 'Accessory 12V' and 'Instrument Light'. Doesn't seem like a good idea to me, I am writing an enquiry to the supplier now - they suggested that one of the wires needs to be cut, and that the wiring appears to be different to D-MAX and non-Australian MU-X cars.

: The provided fascia/head unit doesn't really seem to have all the parts required to completely secure the head unit to the car. I cannibalized some parts from the car's original head unit, but have yet to really securely screw the head unit down to the car - GROWL have pictures of the DIN rails in my MU-X and say they will make a bracket for me and other Australian MU-X buyers.

Would appreciate any advice e.g. is this likely to be a AN-21U? - it probably is, thanks Kaween!

( I can change the boot logo now! There were no Isuzu logos in /etc/logos, so the GROWL team sent me two files Isuzu logo and MUX logo.

Thanks, David

[MENTION=2324592]DavidFong[/MENTION]

* Has TH-roots, that's for sure. the mcu and version codes are identical to the AN's. Not doubting this is some variation of AN.

* non working passwords : try NOT entering anything. Just press OK. I've been informed that on several 2.9.3's, the users can enter these without any code at all, they just press "ok". Can't vouch for it, but you never know till you try the obvious. :)

Euh ? Yes. It's a MST786 dual core Cortex. Most of them run on 1.0Ghz, some report 1.2Ghz. Afaik, all of them run a 4.1 core as there's no other droid version available for this platform. (at least not that I know of)

Searching for Dashlinq4 Radio.apk

Hi people.

I've launched this question already on the dashlinq4 specific part of this forum, but that forum part seems a bit slow/low members.

Anyhow, if anyone has access to the radio.apk of a Dashlinq4 unit and would be willing to share this APK, I'd be very greatful.

Reason : the Dashlinq4 is the Ca-Fi version of the AN21-U, or at least it is a close relavive.

Anyhow, the Dashlinq4 has a radio APK that has a very different setup, and I've seen it working and showing a fully functional RadioText part.

It would be interesting to know if it is possible to run the Dashlinq4 Radio.APK on the AN21, and if this would have an impact on the Radio-Text issue that seems to be typical for all the system versions of the AN21_u I've seen so far.

Thanks in Advance,

Sub or speakers, not both

I've ran into a very strange issue, if I use the subwoofer output it will disable the 4 speakers hooked up directly and all I have is the sub going. As soon as I unplug it, the speakers work.

Any idea how I can have it not disable those speakers?
[Android Head-Units] kaween:
..... a couple of questions first :

1) has it worked till now, or is it a new setup ? I suppose its an active subwoofer yes ? (.... the subwoofer output line of the AN21 demands some kind of amp in or before the sub. I'm not looking to insult you, but I've read about people who think they can just hook up a 2Ohm sub to the sub-out and think it will work).

2) Honestly, It sounds as if the subwoofer is overloading the amp. Is it possible there's a shortcircuit on the sub-connection ?

3) I've not used the sub-out of my AN21 for ages. Main-reason is the lack of "anti-pop" circuit in the AN21-u that causes a nasty "pop" whenever you change volume or mute the unit. What happens if you hook your subwoofer a cinch-audio out of the unit ? (please be sure to check for a shortcircuit in your subwoofer's circruit or cabling first !!!!). I've hooked up my subwoofer that way (2 channel rear connection to the sub's amp), I've lost my subwoofer-level control by the AN21-U by doing that, but there's no nasty "pop" whenever I change volume or whatever when hooked up like that).
[Android Head-Units] roystervi:
Hi I had a problem somewhat like yours. All of my speakers would just chip out then back on in a few min then out again. It's turn out my speakers was too much for the amp. Have you try disconnect the speakers from the amp and try just running the amp without the speakers.

maybe you need to use a meter to see if your amp rca middle pin has a ground with any speaker or the unit case.

Hope this helps any info if info l always way.
[Android Head-Units] freetacos4everyone:
1. Existing setup, hasn't worked at all with this new head unit. (you are correct the head unit's subwoofer output is fed to an amp before the sub)

2. Doubtful as typically the amp will shut off when overloaded (it used to when it was bridged and I cranked it (previous head unit of course)) and the sub is fully working when hooked up, the issue is ONLY the sub works. All hard wired speakers get disabled until the "subwoofer out" is unplugged. (Like it shifts to using the RCA/composite for audio out (I haven't gotten to test this theory))

3. I will try that here shortly and let you know. I don't mind losing subwoofer control, it just seems like really odd behavior.

Also I've tried reseting it with no luck, and thanks for your help.
[Android Head-Units] kaween:
.... I'm not looking at the sub's amp when suspecting an overload. It sounds as if the AN21's internal amp is going into overload. Sorry if that wasn't clear.

Can't imagine resetting would make difference.

[Android Head-Units] kaween:
Nicely done. I suspect the 2 side cams are build in the underside of your side mirrors ?

The way the unit reacts makes me presume you forcefeed a 12V to the back-cam line the moment you switch to the specific cam you want to see to get the back-video line to show the picture. What kind of switch do you use to select the cams themselves ?

Hi,

are you sure the dashlinq4s are close to the AN21-U? The firmware updates on their site are neither encrypted nor the filenames of the APK files look like ours (com.tw.radioxxxx and theirs is just CarFM.apk).

But anyways, as one of your posts helped me with my SWC, this is my way of saying thanks (see attachment) :)

P.S.:

With my (very) limited programming knowledge I found out where the RadioText is updated and what is done there:

It seems the received radio text gets just a normal string operations (replaceAll with replacement parameters from " +" to " "). Then the unit compared the received radio text with the one already stored (equalsIgnoreCase) and updated the appropriate text fields if the received text differs from the currently shown..

What's cooler though is, that the radio text seems to be put also into the widget! If I would have known about the dashlinqs earlier, I would already have a custom fit Android HU from dashlinq4 in my ix35 :D

Good to hear (no pun. oh, actually might as well) it works. ;)

But the situation is a bit odd I admit.

[MENTION=1071291]ssj[/MENTION]

Hmmm. That would mean something must go horribly wrong in the service that compares the strings (although that seems to be correct), or the result in the two buffers gets corrupted somehow (overflow ? unlikely, admit I don't fully understand the code as-is). But something is broken there : a written string for example that is shown will _not_ be overwritten by new info, nor will it be cleared when the compare fails even after the actual station is switched.

I wanted to compare "non working" rds TX data with working rds data, but I'd need a soundcard able to capture at 192khz in order to let RDS spy work - and I don't have that around. :(

It would be interesting to have a modified apk that simply dumps the result of the RDS manager call, without any compare or whatever just to see what is dumped there.
