Has anybody here ever solved a broken EQ ?

Hmm. Tried the 2.7.29 today. UI unauthorised blablabla. Solved the UI warning.

BUT. Hardwarebuttons (Home/Back/Menu) didn't work anymore. I know I can "learn/assign" them, but in 2.7.29, this did NOT work : the "learn buttons" routine starts, they even recognize the actions, but afterwards, they do NOT work. Odly, SWC still worked, but even if I assigned home/back/menu to SWC buttons, they would be learned, but NEVER executed. I might have done something wrong, but for the life of it I've got no idea what.

Sad, because I kinda liked the layout of this version, and the radio app works better (the RDS Radio Text is a lot better readable) for example.

Crap. Ah well.

Question 1 : I'm searching high and low in these 480-or-so pages, but I seem to miss if anybody here ever was able to resolve their "my EQ settings go byebye once I switch my Radio Tuner to another input or Navi starts to speak". Any pointers would be highly appriciated.

Question 2 : Who has ever started a factory reset on these units ? What happens EXACTLY ? Am I right in the assumption taht :

a) all 3th party software (also those who may have been preinstalled by the seller, stuff like navi software ect) will be WIPED,

b) all USER variables and previous settings of all default apps will be cleared ?

c) Also, lets say the machine came with a 2.7.0 for example, but the user had updated the machine to 2.8.0. When you do a factory reset, to WHAT version would the system revert ? 2.7.0 or 2.8.0 ?

d) If you updated the MCU, would the MCU revert to "factory reset values" too ?

Of course, I could try this myself, but I'd rather know up front what I can expect.

Any insight would be highly appriciated. I may be an MSCP and ACTC, but I don't know nearly enough about these devices to feel fully comfortable. So some patience and pitty for this old geezer, please ? :angel:

I have sort of solved this problem by changing my mcu
[Android Head-Units] kaween:
Hey, thank you for your message. But I don't like the sound of "sort of" as it implements a not-fully working situation ? I've send you a message in my attempts to become a bit smarter.

Anyhow, for those who're having the same issues. I "sorta" solved it -at least as a stopgap- by using a wrong MCU (Bad hardware revision, correct feature list). Because of that, my OBD, BT, RDS, colour buttons and the whole bla-di-bla works, and my EQ behaves againg, and my radio sound really well (used 2.7.28, 2.7.29 did some odd stuff and I couldn't use my hardwarebuttons anymore).

Everything works, EXCEPT the rotary knob for volume control. Although I have a good working SWC with Volume control, I was worried what would happen if for some reason the SWC would fail, so I reprogrammed my hardware buttons (Home and Menu) into acting as "Volume +" and "Volume -" at normal keypress, and "HOME" and "MENU" when I long-press them.

Ah well, time for bed. Tomorrow is another day. I've got some chinese seller to bug and get me the correct mcu which I lost because HE send me a firmwareflash without the correct MCU. :rolleyes:

Flac with album art

So, here's another issue I bumped into with the stock music player.

For me generally flac files play fine, with or without tags, but if I include album art in the files, they won't play. The music player shows the tags and album art, but just stays at 0:00 and not playing the track, and the UI starts lagging until I change to a different track without album art.

I don't have this problem with MP3 files. They play just fine with or without album art.

It would be nice to know if anyone else have experienced this, and especially if they have found a way to fix or work around it.

I might just convert the files to MP3 and be done with it. :)

/Miwer
[Android Head-Units] MFKinSINY:
I just discovered the same issue over the weekend. I have 128 GB usb stick with almost 90 GB of mp3's which I meticulously tagged over the course of 6 or 7 years. They all play & display perfectly on PowerAmp. A few weeks back I put a few (unformatted) FLAC files to see if they'd work & they did, so I spent a few weeks ripping cd's to FLAC & tagging them. They wont scan into PowerAmp properly and when I use ES file explorer they play.(they wont display the album art) But after a few seconds, playback stops and I get error along the lines of "cannot find next file" or something like that.

I was considering removing all the tags, but will try only removing the album art first BUT I'd much rather find a proper fix. After all, album art is a nice feature. Let's keep each other in the loop on any findings with this please. good luck

New firmware available 2.7.38 : https://yadi.sk/d/pZQq74RUaJ3CS
[Android Head-Units] apogee82:
I saw this too but didn't install because it has third party advertising? Anyone want to be the guinea pig and verify that this is only a translation error?

[Android Head-Units] Miwer:
Hi,

I'm very interested in knowing what version MCU you came from, and what version you are using now. I still have EQ problems, and using 4.3.2-1-10-2101 MCU with sw 2.7.28.

Also if you hear anything from your chinese seller, please do keep us informed ;)

/Miwer
[Android Head-Units] apogee82:
Sure ... it's at the 4pda.ru thread. It's all in Russian but they post regular MCU updates. There is a pinned post at the top of each page in the thread with links to the different versions. It's the orange section, "Прошивки", 5th section down.

http://4pda.ru/forum/index.php?showtopic=522762
[Android Head-Units] Miwer:
Using 32GB SD card here, so It's most likely not an SD vs. USB issue.

I don't have PowerAmp, but your stating that it's not working there either, suggests that it's a general problem with the android version we have (4.1).

I found this article - where someone else is having problem with flac playback on android 4.1.

https://romaco.ca/blog/2012/12/01/fix-flac-files-not-playing-on-android/

The only difference between that and my case is, that my flac files don't have any ID3 tags, so I cannot use this fix. In my case it's the album art that's causing it. Removing the album art fixes it for me, but I like the the album art, so I went ahead and encoded them to MP3 and then it works with album art. I still have the flac files on my PC...

Best way would be via skype, pumpkin_cool, although be aware that as he is in Hong Kong it's not always that convenient for us in the UK (assuming from your post that is where you are from) to contact him. He is usually online from around 1am until 9am GMT.
[Android Head-Units] patrickoneal:
It doesn't report 1.8Ghz, it reported near 1,800 bogoMIPS. They aren't the same thing. There doesn't seem to be an easy way to determine the actual clock speed that I can find. It could be 1ghz, or 1.2ghz, or 800mhz, who knows. Being that the 1.2ghz and 1.0ghz machines report similar numbers, one of the sets of specs is likely incorrect unless some throttling is going on at idle.

---------- Post added at 02:14 PM ---------- Previous post was at 02:08 PM ----------

I just left everything hooked up in the PC, then chopped the SATA end off of a molex to SATA adapter. Then I hooked the yellow(12V) wire to the battery and accessory wires, and the ground connection to one of the black wires. I did it this way so I could plug in the stereo to the PC power supply without cutting any wires or worrying about needing dummy loads to get it going. I just have to power on the PC to get it going.
[Android Head-Units] KID52:
My mistake, I must have misinterpreted the post regarding this bogoMIPS information.

I didn't know that a regulated desktop power supply was a computer PSU ;) Although I guess really they are the same thing...

If you removed it, it's extremely simple to get running, just connect a black wire to a green wire on the 24pin connector - either a piece of solid core wire, or a less technical paperclip will do. Then as mentioned above, the 12v and ACC wire go to the yellow wire on a molex, and ground to the black wire. No need for a dummy load if you have the stereo connected. If you really feel paranoid, connect a fan or two up, but it's really not necessary.

You are supposed to have a dummy load if you are constantly disconnecting things, as the PSU likes to put out at least some power, but as you are likely to have the PSU on with the stereo on, it is irrelevant.

How long should the factory reset take? Been about 30 minutes still resetting.
[Android Head-Units] djblaze852002:
Thats happened to me a few times. Just turn it off, it should boot up normally even though you were in the middle of an update. And try resetting it to factory again.... It should work this time and take no longer than 5-10 minutes.
[Android Head-Units] KID52:
When you say a few, how many times did you try to reset it, and how many times did it not reset properly?

Also, what system version are you using?
[Android Head-Units] kmtk:
"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit ...

Reset worked.

First thing I tried to do is take screenshots but that's not working. I get an error message "unfortunately settings has stopped" if I try to grab a screenshot of the about device page.

If I go back to the home screen it takes a screenshot but then isn't able to save it.

Out the box it had a godawful live wallpaper of a nest and birds. After a factory reset it's a picture of a snow covered field. There's also a video manual.

MCU version: 4.1.0-1-10-2101

System version: 2.6.62

Ill post more details of the unit tomorrow.
[Android Head-Units] KID52:
This feature was broken in earlier system versions, from my tests it works fine as of 2.6.60 I believe. It's written in the bug list in the first post.
[Android Head-Units] kmtk:
It came with 2.6.62.
[Android Head-Units] KID52:
That should be the latest version as far as I know, or at least, the latest version I have the files for.

Cannot say why your screenshot feature does not work though.

Where did you buy the unit from out of interest?
[Android Head-Units] kmtk:
"AN-21 U" - Unbranded 6.2" 2 DIN Pure Android 4.1 Car Stereo Radio Head Unit ...

Newdealstore2012 on eBay.
[Android Head-Units] KID52:
Ah okay.

It's interesting that these sellers are going to the effort of installing these pirated apps. Clearly not even a bulk order allows you to customize the firmware , as the apps disappear on a factory reset (based on your post, and the experience with my unit).
[Android Head-Units] djblaze852002:
I have tried to reset it a few times when I failed at getting google voice to work through various hacks and sideloaded apks. Also when I would lose audio as described in my earlier post. (I now know that by opening the movies app the audio fixes itself). I cant explain why it fails. I has done it twice to me. But shutting it down and trying again seems to be fine. I am on the latest firmware.

Has anyone tried or been able to get google now to work. I would really like to give my car commands like play music by artist "whatever", or navigate home, or whats the weather going to be. I have been unsuccessful in getting anything to work properly.

Has anyone had any issues with Google play music not playing the next song? I am constantly having to press next to get the next song to start playing. I am trying different things but have not nailed down the cause. A few ideas: I think that if I am going to switch back and fourth between music app and navigation that it is best to do it by pressing home then pressing the icon of that other application rather than doing a "fast switch" using the notification bar pull down which shows my 2 running apps. Another thing is telling google play music to not cache songs... There could be something else too that I haven't thought of, but I am still testing things to try and resolve the issue.

I wish there was a way to fragment this thread into sections like (Buying, hacking, general info, etc...) I hate hijacking the thread with all my minute comments and details about the unit, I just want potential adopters to know exactly what this unit can and cannot do.
[Android Head-Units] avgaz:
Hi! someone could not start usb Bluetooth? how to do it?
[Android Head-Units] kmtk:
Have you tried the latest firmware linked in the first post?

Seems different than what is on the unit after a factory reset. It's running 2.6.62, but installs all these apks after resetting. And as I've said before, I can't take screenshots despite being on the latest version. I'm going to try installing system 2.6.62 linked in the first post tonight.
[Android Head-Units] tarzansg:
Trying to differentiate

I having been searching around, and on the same page with you guys talking about different variation of the similar look-alike unit. I found one different on the back of the unit where the USB cable are located, the unit found from pumpkin_cool is somewhere at the center, the other i found from esson tech in Ali-express is coming out from top right hand corner at the back of the unit. I want to find out from your observance and hopefully advise which is the newer version? see attachment for images between the 2 i spotted.
[Android Head-Units] tarzansg:
What is the box

As I realized at least you and another forum members has already bought from newdealestore2012, i am consider buying from the same store too due to much more attractive pricing.

However comparing against the pumpkin cool store, i also noticed about "what in the box" description. newdealestore2012 did not mentioned this item "ISO Wiring Harness". I would like to find out from you if you have that in your packaging?
[Android Head-Units] PsychoMcSatan:
The pictures you show are virtually identical and are quite close, but not exactly like mine. This leads me to believe that these are all pretty much the same core and the individual distributors make superficial customizations. Just make sure you get capacitive screen, dual core 1GHz, running Android 4.1 and you'll likely get what most people on this thread have.

One thing I noticed from your photos is that neither have the mic-out that mine has. However, I can see that the connector that mine is attached to (the one with the iPhone connector and three RCAs) has some unused pins. When I get my new back-up camera and I open up my dash again, I'll see if I can determine the pinout on that connector. It might be that they simply had a shortage of cables that included the female 3.5mm for that function.

-PMS
[Android Head-Units] patrickoneal:
So, your unit has a mic input in the harness? If you could get the pinout, that would be great. It would save me from dissembling the unit to add one.
[Android Head-Units] KID52:
Do you mean a Bluetooth dongle? It's mentioned in the first post these do not yet work, the firmware needs to be modified.

I think the pictures are just generic, they could be of any unit. Mine is not the same as either of those, but is most similar to picture 1. I wouldn't go by what the pictures show to be honest, I would go for the specs.

Actually mine was from Peter Chan. It does not include an ISO wiring harness, just bare wires, I posted a picture a few posts back of the wiring diagram, and those wires are exactly what I got.

Yea, this. The pictures could be of anything, they are all photoshopped with the screen images and stuff too.

What I would like to know, is how the device determines which mic to use, there is no setting for it.
[Android Head-Units] dimant80:
It's not a translation error. This firmware really contains "third party advertising" in form of logo "RP" (RedPower, local russian brand) in stock music player and stock launcher: http : // cs3-1.4pda.to/4979876.png

Also it contain RP's boot animation. Rooting of this firmware is not possible at this moment as i know...

PS Sorry for my english and greetings from Russia :)
[Android Head-Units] jpapadami:
Do not install it. I can't say much about the third party advertising as I didn't look for any. When the firmware first came out there was no additional description. What I do know is that even though you can root it using the Baudi russian version, you loose root every time you boot the device. I went back to 2.7.35
[Android Head-Units] aluzjunior:
Anybody knows how to convert the resolution of the screen to 1024x600? My unit supports it
[Android Head-Units] abicidandan:
Hey guys

Hey guys, I'm a long time reader, first time poster. I got the similar unit (with the two nobs), and I have a few questions for you guys.

First, is it possible to implement my Google Contacts to the Bluetooth Phonebook?

Second, does anyone know why my music turns off when I hit reverse, and the camera input kicks in? Is there a way to avoid this?

Third, what launchers are you guys using for this. What do you find is the most user friendly keyboard for a car?

Thank you so much for all your time and consideration guys. Is there anywhere I can donate to help this unit get to the next step?
[Android Head-Units] Kidmet:
Not sure about google contacts.

In the settings there is a setting to NOT mute during reverse. You gotta look around. It may be in one of the hidden menus.

I am using Nova Launcher and LOVE it.
[Android Head-Units] abicidandan:
I looked and didn't find the reverse mute setting. Can you elaborate please.
[Android Head-Units] jpapadami:
Go to Settings > Sound > uncheck Mute while reversing. Like it was already stated, look around.
[Android Head-Units] kaween:
It's in the settings->sound menu. "Mute Reverse".

PS : Crap, can't delete so it seems as jpapadami beat me to it. :)
[Android Head-Units] abicidandan:
Thank you both. I'll take a look when I'm in my car again, but I'm pretty sure I checked the sounds menu already. Maybe I missed it.

---------- Post added at 02:28 PM ---------- Previous post was at 01:55 PM ----------

One more thing, I have looked around, and many have said that for the double din to fit into the dash kit, you need to trim the dash kit.

Most have used exacto knives. Have you tried heating up the plastic before trying to slice it? Would that work?

Do you guys know of any radio app (that uses the antenna, not internet). I just hate the look of the stock one.
[Android Head-Units] lemach:
Hell guys.

I have purchased this auto radio:

1 - Install baidu

2 - Install Clockworkmod Root and update binaries

3 - Uninstall baidu

4 - Reboot unit.

That's all.
[Android Head-Units] jpapadami:
How did you remove the "Unauthorized UI" red warning? I don't believe there is a modded com.tw.services.apk for this version unless you used one from 2.7.35?

Nichts hält so lange, wie ein Provisorium

[Android Head-Units] kaween:
Be VERY careful replacing the mcu.

I advise you to first check out if you can find a copy of your existing MCU in the file repository. If so, you at least can revert back to your original version when things go south.

If you do NOT find the exact same MCU in the file repository, I advise against updating it. Chances are you'll bust up your Equaliser (at the very least), and take it from me, once the MCU is gone and you don't have a place to find the original back, you're basically up sh*t's creek with no paddle. :eek:

In other words : if your MCU works correctly, do not touch it if you do not have an exact same version as backup somewhere.

My seller made me flash my firmware without even testing himself if my MCU was included. It NEVER was resolved in a 100% correct way afterwards.

PS : shot in the dark : Ford ? Focus or comparable ? Open roof ? (just by looking at the reflection of the screen) :)

---------- Post added at 08:17 PM ---------- Previous post was at 08:02 PM ----------

What version do you have ? The one with the presets on the left and that odd red slider thing ? Yeah, that won't be winning any prizes in terms of looks. :)

Chris R.R. provided a much nicer version here : http://xdaforums.com/showthread.php?t=2528349&page=203 (and onward, he made the files available a couple of pages afterwards) which looked A LOT better.

Another option is to upgrade to 2.7.28. That one comes with the alternative/Winca-like Tuner app which also looks a lot better.

As for dash trimming .... it depends on the material of the dash. I would advise against exacto knives personally and try the very laborsome sandpaper routine simply because it is more controlable.

One slip with an exacto and you have a scratch or blemmish that will haunt you forever. (at least, that would be so in my case). Also, if the part of the dash is painted with something, it will "splinter the paint". I HAVE done it in the past, most of the times it does work, and never needed to warm up the dashboard. But as said, it can be done with an exacto, it may even be the best choice depending on your dashboard material, but it's not my prefered way of doing it.
[Android Head-Units] cool_head:
At the time i only saw a new setting called "brightness mode". The UI and apps looks the same as 2.7.35. There is a 4.3.5.1 mcu update included in the system/etc/mcu folder but only for some HW versions.
[Android Head-Units] abicidandan:
Yeah I have the horrible one.

Those are nice. Do I need to be rooted?

I'll check that out.

I was actually able to do it using the dremel. It doesn't look too bad.

My car is a Nissan Rogue 2010 SL.
[Android Head-Units] kaween:
Yes, you need root for the Chris R.R. version. Root the unit, make a copy of your original Radio APK (call it Old...something or comparable in case it doesn't work out), and copy the Chris version. Other then most on this forum, I don't use Root Explorer or EFS Explorer, I use Total Commander to do this stuff. Also free, and if you know Total Commander (or what it was based upon : Norton Commander) it's a lot more straight forward than RE or EFS is.

If I had used a dremel on my car (Dacia Duster), the dash would probable melt. :)
[Android Head-Units] abicidandan:
Thanks. I'll need to check exactly which model I have to root it, right?

If I had used a dremel on my car (Dacia Duster), the dash would probable melt. :)[/QUOTE]

Mine did melt, that's the point. That's what made it so easy to cut.
[Android Head-Units] kaween:
Mine did melt, that's the point. That's what made it so easy to cut.[/QUOTE]

Yeah, but there's "melting" and "meeeeelting". :) I'm glad it turned out good for you, but if I'd do it in my car, the results would be ... undesirable.

The melting causes discoloration of the plastic most of the times. If you have "white outs" on the ridges and they would bother you : use black shoeshine on the affected areas. Rub it out. You'll only see the rework if you know where to look for that way.
[Android Head-Units] abicidandan:
