I just visited the russian site 4pda.ru and see there is yet a newer firmware available.

2.7.31 has July 11 in the file name and "modified" July 25 at 11:26am

2.7.32 has July 23 in the file name and "modified" July 25 at 4:18pm

I did not download yet, and I refrain from posting links to software or firmware I haven't verified.

No need to apologize, everyone is a newbie... at first lol

This thread is for helping each other and providing info.

I have a bit of a "tough love" approach when I try to help people, hoping it makes eyes open wider. :)

I'm sure you've heard the expression "There are no dumb questions, just dumb answers"

There are few statements truer than that. Best of luck with your head unit.
[Android Head-Units] aluzjunior:
Thanks again. I admit i was too lazy to search.[emoji16]

Só, i have some doubts, i dont know which version of firmware is best (talking about performance, bugs free, features working) to upgrade.

Mine is 2.7.22 Android "4.2.2"

Mcu 4.3.1-11-10-4501

2 knobs (volume and tune )
[Android Head-Units] MFKinSINY:
I usually sit back & wait a few days after a new firmware is posted, to see if anyone reports issues.

Keep your eye on this thread regarding 2.7.31 or wait till 2.7.32 is officially posted in the repository.

I don't have the same HU you have. Mine has a single knob.

But, as far as MCU (there is a post here somewhere [post 3972], explaining the numbering/naming scheme) I would not stray from those numbers.

The last four digits are hardware specific (they correspond to the actual chips inside)

The dash 11 is your hardware version of the HU and the dash 10 is the vehicle make/model. The "4.3.1" is the version, so higher is newer (or better in most cases)

If your bluetooth is working, and audio sounds ok, and the am/fm radio is working as expected DO NOT deviate from x.x.x-11-10-4501

Oh, and by the way 4.2.2 is not really 4.2.2 it is 4.1.1 quite a few posts on this subject too. It is "faked" There is no 4.2.2 for this unit, as far as I am aware.

Good Luck my friend.

Quoted from one of my older posts:

If yours is in fact identical to the one on the first page of this thread (as is mine) at the very least make sure your MCU ends in "01"

Those two digits (according to Miwer in post #3972) identify the radio chip & the audio chip. Make sure your hardware version is correct too. You "should know" what MCU you started with. Mine came with 4.0.6-1-10-0101 and now I'm running 4.3.1-1-10-2101 (the "21" gave me color option & color app which has no effect on my unit with blue leds, not rgb leds) but there was never an update for -0101 so I took a chance. The -1- is the hardware version. Make sure yours is correct. (maybe there is some kind of identifier like on the sticker, or inside the unit)

The -10- is the vehicle make/model (see the post I mentioned above)

Like I said, the last two of the four digits are the chip identifiers and can affect your audio & radio. The first two of the four digits are your "features" and may knock out bluetooth and/or your DVD amongst other things if not correct. You definitely "should know" the MCU you started with. MAYBE (I'm not sure) a factory reset would get you that MCU version and you can update firmware & MCU from there as well as reinstall any apps. AT THE VERY LEAST make sure your hardware version and your chip identifiers (and also your features) are correct. The first group of numbers (before the -1-) is the software version and the higher the number, the newer the software (or should I say "MCU" version) IF your unit is the same as mine, you'd probably be safe with 4.3.1-1-10-2101 but I cannot say this with 100% confidence. Good luck!!!
[Android Head-Units] aluzjunior:
its true when we update he system get a "mcu reset" and i need to choose car type to set the correct again?

2.7.32

New firmware

https://www.dropbox.com/s/7to4pd9z80z4ghf/2.7.32_23.07.2014.zip
[Android Head-Units] Miwer:
Allegedly... Like I wrote in post #3972, I'm not sure if this number really means hardware revision - it's a guess based on certain circumstances (also in my post).

I would like to find out more about this, but I'm no expert at reverse engineering and disassembling, so it will take some time and there's no guarantee of success. ;)

I'm interested in finding out after [MENTION=5873920]Skratchuk[/MENTION] fixed the EQ reset problem and got better sound in post #3963.

I tried 4.3.1-1-10-2101 and I still had EQ resets, so I downgraded to 4.2.13-(same), which fixed EQ reset for me. Still have poor sound quality though, and I don't know if the -11- version fixes this. Since I don't know yet what this number means, I'm reluctant to flash it, at the risk of bricking my radio.

Also "better sound quality" is subject to opinion... In my case, it's not really bad, however I'm lacking some bass compared to my stock head unit (Skoda Swing), and the EQ settings are not really compensating for this. I'm thinking of building a sub for my car, but this is only meant for the sub-80Hz frequencies, and I feel the unit is lacking in the 80-200Hz range with the built-in speakers (stock unit was better in this range)

My radio (post #2981) came with 4.2.5-1-10-2101, and I have always stayed with the same numbers after 4.2.5-*
[Android Head-Units] Cebulon48:
Hi,

I installed above version 2.7.32_23.07.2014 . Seems to be another fake 4.2.

Other than that, I get the UI not authorized message. Since I can not root my device (T7019a) I reverted back to 2.7.28.

Can someone please recall which version was the version (latest) with the icons at the bottom row. I'd like to use that one in the future since I don't really like the four widget version.

Thanks in advance

[Android Head-Units] KID52:
What I don't get is this flickering. Speaking to Peter Chan, he pointed me to a variable resistor I could adjust, and this did slightly improve the flicking (turning the other way to what I did makes it far worse), but still not perfect. I can only assume the signal is analogue going into the screen, as it's not a backlight issue.

What would be great is a digital IPS panel of at least 720p, and 7" rather than 6.2", I bet that would take the cost up a penny or two though...
[Android Head-Units] KID52:
Take the screen off first, two screws on each side. There are two ribbon cables and a USB cable to disconnect.

Remove all screws on the rear panel, and unscrew the GPS socket (but you cannot remove the panel yet) then undo the single screw on either side at the bottom.

Put your hand in the unit and remove the ribbon cable going to the DVD drive, then pull the top off (this is three sides, so top, left, and right panels).

Now you have access to everything, there will be a fan cable, and a USB cable to disconnect if you want to remove the back panel.

Then 4 screws hold the main board to the bottom panel.

I too thought about a panel mounted socket, but I don't have enough room for one of those and a straight microphone connector, I would need a 90 degree one which I do not have, so I simply bought an extension lead, cut one end off, and soldered that on with the lead trailing out the back.

Edit: I think actually when I put it back together I did it slightly differently, but I cannot quite remember. A little tip though, you may need some thermal paste, as the voltage regulator at the back of the unit is screwed to the backplate with paste inbetween. I chose to replace the paste, but you probably don't need to. Be careful though, as if you accidently touch it you will end up with fingerprints everywhere :)
[Android Head-Units] patrickoneal:
Does it flicker if the engine isn't running? If it's alternator noise causing the trouble, a filter could certainly help.

Running mine off a PC power supply, I haven't noticed any flicker. Not that I'm particularly impressed with the screen overall. When I tear mine apart, I'm hoping there will be a part number on the screen. I'm wondering if the touch panel is bonded to the LCD or not as well. There seem to be a few 6.2" lcd panels on aliexpress, and it would be nice if one could swap in a better quality display. It's a long shot however, and it would need to be a better screen with the same dimensions and connectors.
[Android Head-Units] KID52:
It's sat on my desk connected to a regulated desktop power supply, so no engine in sight :)

The flicker is only noticeable on dark grey screens such as the settings menu.

Unfortunately I think that is wishful thinking. Firstly just finding a compatible screen with the right connections/driver board, and then if you somehow manage to find that, then being able to find a better quality screen.

To be honest, I don't think you will gain much. It seems unlikely you will be able to get a higher resolution one that would begin to be compatible, and the only improvement you can make for the viewing angles is to go IPS or equivalent (I haven't seen a TN panel with good viewing angles yet). If you look at this unit from the right angle, it looks as you would expect. I admit that with it in the car it looked a lot better than when it is sat on a desk.
[Android Head-Units] chris.r.r:
I mean all source classes are named like, a, b, c, d and so on, which makes it hard to find references between classes. This is IMO a good indicator for obfuscation. Moreover, it wasn't possible to convert the smali code to Java code for whatever reason (I thought obfuscation probably). So changing single code lines directly in smali (if you know what you are looking for) is fine, but changing larger code sections will be tough. Smali remains too magic for me, for interpreting bytecode I'm not expert enough ;)

Maybe there is someone, who can manage that. Would be great.

AD2P support..

I all, i've looked though about 29 pages so far and looked though countless Ebay ad's.. I'm trying to find an answer to a simple question... Does this unit support A2DP to my Iphone. I want to stream music from my phone and I may wirelessly stream music from Pandora on the unit it's self or though my phone if I don't decide to tether.

Anyways, I know most owners here are not on that other side of the camp, but I'm replacing the Head unit on my 1987 supra from and old kenwood MP3 CD that I bought like 10 years ago to something modern with a NAVI.

I noticed none of the units come with the TV tuner anymore? Do you know if you can get digital channels with the TV unit?
[Android Head-Units] KID52:
I didn't think it was possible to reconstruct the java files from smali anyway?
[Android Head-Units] KID52:
You can stream music via Bluetooth, yes. But I would advise you to just use the apps on the unit, such as Pandora like you mentioned.

It's only the cheaper ones that do not come with a tuner, it's done purely for cost-cutting. Actually one question I have for those that ordered from a listing that did not mention a tuner, do you still have the TV app? And if you don't, does it get installed when you update the firmware from the files in this thread?

If you want a digital tuner, either find a listing that offers it as an additional extra and contact the seller, or just contact Peter Chan directly and he will sort you out. He probably won't be able to offer you the cheapest price as he only orders on a per-unit basis as far as I can tell, but the service he offers is extremely good - especially if you want little extras that the standard unit does not have. The other option may be to use a USB tuner, which are extremely cheap, and someone on this thread purchased one said it worked for SDR, however I have yet to find a TV application for Android, again if anyone knows of one please let me know.
[Android Head-Units] omarko:
bummer, my unit has not been posted yet ... the seller just told me that the shipping company is refusing to post the parcel to Australia (coming from China) because it has a magnet inside (the GPS antenna has one on it)!!!!

Anyone had this happen to them before?

Fingers crossed they can work something out but I am starting to have a feeling that I wont get this before Xmas :(
[Android Head-Units] djblaze852002:
First Impressions

Had some time to test thing out with my unit...

Google Play Music:

Seems to work fine at first, however it doesn't seem to like playing music tracks continuously. It will play the first song selected until the end, then stop and not play the next tracks. I unchecked the "cache music" options in the settings and that seems to have helped a bit, but I am still finding that google music will cease to play songs after the initial track I selected.

Another issue I had was while playing music with the ignition key on, but car not turned on, THEN turning on the car, there is a brief cut out in power. It has occurred to me a few times where sound from any android apps will stop working. I reset the unit a few times to solve the issue which is a pain. But I notice now that opening the movie app seems to fix the issue and restore sound playback. This has also happened at other random times, when doing something makes the unit lose audio. Again, opening the movie app seems to help.

Google Now:

I have yet to get this to work properly. When i tried to use it initially it said i could not use Google Now because my Google play services was not up to date even though the market did not offer an upgrade option (It was stuck on version 3xx) I manually sideloaded the latest 4xx version and still google now is shotty at best. The "ok google" command doesnt seem to work anywhere. Pressing the microphone in the google search app seems to work okay, but is still finicky...Due to not getting this working properly, I have been unsuccessful in getting GEL, or OpenMic + to work at all.

Google Hangouts:

Works okay. Options to make voice or video calls do not seem to be available. Only basic chat functions seem to work.

Plex, pandora, waze, google maps, chrome, airtight, nova launcher, and avaite all seem to work fine. I will continue testing more apps and features we can unlock though apps.

I really hope google play music doesnt keep botching up like it has been. It was one of the main reasons I bought the unit. With google play all access and my 4G hotspot in my car I hoped to have access to unlimited amounts of music all the time.
[Android Head-Units] KID52:
I'm still not sure why you seem to be having such an issue with the Play Store, mine simply updated automatically, and has done without fail every single time I have factory reset the unit or installed a different firmware.

I found a similar issue with my unit restarting when I start the car, I believe this to be down to the car taking all of the juice to turn over (although I find this a bit odd as I've replaced the battery with one that has a higher capacity and discharge rating). Although as I use the default music app (for now), I don't have any audio issues. This should be easily solved with a capacitor and a diode though,
[Android Head-Units] :
How did you connect the Radio to the Desktop PSU?
[Android Head-Units] zazzn:
Hi all,

About to make a purchase, but I see pricing ranging from 300-550$, I can't for the life of me see the difference in the units. Some state that there is a A9 1.2 GHZ processor... Is this fluff? Or are they all 1.2 now bumped form the 1.0 that was sold a little while ago?

Also the seller claims that I can't use the Lighting adapter with my Iphone. Since I do not want to purchase a dongle for 3G, and add an extra monthly charge I was wondering if A2DP was my only option for playing music though my Iphone 5.

Thanks,
[Android Head-Units] KID52:
I just connected the 12v and the ACC wire to positive, then the ground wire to ground.
[Android Head-Units] KID52:
It is explained on the first post in the FAQ that the cheaper units do not come with a TV tuner, also some are resistive not capacitive.

The CPU is a 1GHz CPU, someone just a page or two back purchased a unit that had a "1.2GHz" CPU, but the unit reports the same speed as the one I purchased advertised at 1GHz. Although for some reason it reports a 1.8GHz speed...

There is an iPod app, but I have no idea which iPod/iPhones are compatible with the unit. Could you not use your phone as a wireless hotspot if you need a net connection?
[Android Head-Units] PsychoMcSatan:
Yup, this is due to the power being drawn to start the engine. I had similar issues with my previous radio, a Pioneer AVIC. My voltage drops to about 10V. The amount of voltage drop varies for every car and battery, but while a bigger, fresher battery will help, there will always be some drop due to the current that a starter motor requires.

In support forums for my Pioneer, some electrical engineer folks came up with a simple circuit that uses a couple diodes, capacitors, and a few rechargeable AA batteries that will maintain the 12V to the radio when your main battery drops. Some folks discussed just a big capacitor and a diode, but this circuit turns out to be a little more stable.

I already have such a circuit installed, but I did try to bypass with this unit and I got screen blanking and even a couple reboots. I've hooked it back up and I'm fine again. So it seems that you may just be dropping a little, but mine going down to 10V (or probably even less by now... old battery) has more serious consequences.

Below is that discussion and I've attached the schematic that I ended up using.

[Android Head-Units] chris.r.r:
Not directly, that's right. But with JD GUI it's possible to convert the classes.dex of an APK into Java source. Helps a lot to interpret the smali code. Worked fine for the "old" OUKO source, but it doesn't for the A21-U.
[Android Head-Units] Blaze Falconburger:
I am tempted by the an-21 unit and I think I have found the UK model here ?

Can I ask how does it handle large volumes of mp3 - e.g. can I plug in a USB hard disk (powered via hub or other external PSU if the head unit cannot power it directly via USB) and mount it and just browse it to select an album to play?

I don't want to have to catalog the mp3 files as this will take a long time and for some files I don't have the ID3 tags set anyway so this won't work. I just want to browse at directory level.

Has anyone found a limit in terms of number of MP3 files or size of HDD yet? I am thinking a 500GB HDD with ~100,000 files?
[Android Head-Units] KID52:
Looks to be correct, but the price is fairly high. I would recommend either contacting Peter Chan directly, or trying to buy from one of the other listings on eBay - people are reporting that they do now ship to Europe. Remember, that unit is still coming from Hong Kong, so import fees will likely need to be paid, otherwise if it were UK based the price would not be so bad.

The stock music player is done by folder, there is no way to use playlists. It should support a USB hard drive without issue, although I have not tried one. If power is an issue, you can just use a powered USB hub.

As far as limits go, the specs state 1TB, but no idea what it actually supports. Same with files, no idea on the real world limit. You can use any Android music app, but for now, steering wheel controls do not function with anything but the default one. I think 100,000 files on a 500GB hard drive is a bit optimistic, for 320kbps files you are probably closer to 50,000.
[Android Head-Units] Blaze Falconburger:
Thanks for the reply - how do I contact Peter Chan directly?

Hi, I am new to this forum as I discovered it because I bought the deck in this thread. I have read of much of this thread as I can handle, but well over 100 pages lol. I have a few issues with my deck but I was wondering if anyone has a solution to my main one that just started. Today I started my truck and the unit started flashing as it booted normally and all the apps run normally but the screen flashes black every second then back to normal. I am hoping this is a setting or programming issue and not an issue with the deck itself. Can anyone lead me in the right direction or have a solution? I have owned the deck 2 months with zero issues.

Thanks,

Play Services issue with Pushbullet

I am trying to run Pushbullet on my unit but when I try to sign in to my google account with it, Google Play Services crashes. I read on here about updating play services so I uninstalled it with Titanium, installed it from the play store which all went fine, and tried again but it is the same, still crashes when I try to sign into pushbullet.

Any ideas?
[Android Head-Units] aluzjunior:
I googled but not found. Theres any compatible 3g dongle with external antenna conector?
[Android Head-Units] Miwer:
I'm looking for this too but I have not found any.

I actually have 4 different huawei dongles, only one of them with external connector, but alas, not compatible.

I'm thinking about just opening one and solder an antenna wire directly to the board, and connect that to an external antenna.

Which MCU update to use???

Hi guys

Hope someone can help.

My original MCU version was 4.2.5-1-10-6101

I am trying to find a replacement for the latest version ie 4.2.13-1-10-6101

The closest I can find is 4.2.13-15-10-6501

Can anyone recommend which MCU I should be using? I am having one or two issues with apps on the current version I have installed and my volume dial on the head unit isn't working properly.

I have looked on the manufacturers website and it appears that my model is a TH8586 although it is very similar to the AN-21 U on this thread.

On a side note, over the last few days my Sygic GPS app has stopped working. just hangs during start up. Anyone else been having this problem?
[Android Head-Units] aluzjunior:
if you read the entire post, you know you should not replace the X.X.X-1-10-6101 with X.X.X-15-10-6501
[Android Head-Units] Skratchuk:
This is true but I had trouble with my eq keep reseting on the radio so I changed the mcu & it sorted the problem and even sounds better than my mcu! Could be because I had the wrong mcu I'm not sure tbh but I did try alot of mcu ' before it would work properly with everything.

Other than that, I get the UI not authorized message. Since I can not root my device (T7019a) I reverted back to 2.7.28.

Can someone please recall which version was the version (latest) with the icons at the bottom row. I'd like to use that one in the future since I don't really like the four widget version.

I have not read the whole posts in this topic. There are 500 pages! This is why I'm asking the question. All appears to work ok on the 6501 version with the exception of location services which can't find GPS. This I have remedied by loading Torque at startup.

The only other issue I have is that after having a problem with Sygic (corruption in app data) I had to do a factory reset. This appears to have messed up permissions at a file level on the internal shared storage. Is there a way of setting the permissions of all files/folders on the internal SD card?

And back to the original request... Does anyone know where I can get the 4.2.13-1-10-6501 firmware? I have an Vauxhall/Opel Vectra so I'm guessing there would be no issue with using a Vauxhall version of the firmware??

---------- Post added at 09:27 PM ---------- Previous post was at 09:22 PM ----------

2.7.29 is the latest but you need the updated ui file as well.
