Thanks [MENTION=5246215]bencyp[/MENTION] and [MENTION=4736782]kaween[/MENTION], I am waiting for reply, but in China they are right now with the new year holidays so I'll have to wait... Can you tell me how much did you pay for these new motherboards?
[Android Head-Units] bencyp:
145$ including express shipping to India.
[Android Head-Units] wanxu:
Thanks. Good to know. Bad to know how much :P
[Android Head-Units] bencyp:
What happened to your current motherboard? How did it fail?
[Android Head-Units] wanxu:
Mine is this one: http://www.audiosources.net/prod_view.aspx?TypeId=50017&Id=191&FId=t3:50017:3

I installed a bad bootloader animation so the unit start but after bootanimation everything was black. The solution was to overwrite this bootanimation, so I had to flash the firmware again. As my unit doesn't have some buttons, I couldn't do it easily like everyone here with menu button, SD and knobs, so my chinese seller sent me a firmware and told me:

I didn't understand clearly what was she asking me to do, so I tried something but unfortunately it made the device die...
[Android Head-Units] bencyp:
This is a 8" screen model without any button and DVD player. Mine is 7" with DVD player the motherboard cost may be different for yours.

If you have not installed any firmware yet and still it boots into black screen, I suggest you keep resetting using the button hole. IT happened to me also but I did couple of reset many times and it came back to the main screen and from there I deleted the bootanimation file.

Bluetooth issues with various firmware versions. Need advice..

I got BT issues with every tested firmware versions. BT works fine right after update, but when unit is rebooted it doesn't work anymore.. Anyone experienced similar issues and is there a known fix for this?
[Android Head-Units] TheSSJ:
Hi,

thanks for the tip regarding V4A, will try it as soon as possible :) Does it also work when I can only temporarily root it? After a reboot su access is lost and I need to restart the whole rooting procedure...

Gala is turned off, as my original car radio had this feature and I wasn't a fan of it... :)

Thanks for the advice!
[Android Head-Units] hellad:
There are a lot of discussions you can find about BT problems. For example here some solutions were offered and tested.

It seems that most of the problems were solved in 2.9.3 firmware.

Btw you didn't specify your device, BT version and MCU update version. Only guess we can.

---------- Post added at 11:45 PM ---------- Previous post was at 11:34 PM ----------

Update does not work from usb. As it was metioned in ealier post, you should copy firmware files either to the root of inserted SDcard (GPS one in case you have two SD card slots) or to internal memory (sdcard folder, but take out all external SD cards and HDD attached in this case).
[Android Head-Units] safkafin:
Thanks. I also found the same discussions. Anyways, I got BT now working with firmware ver2.8.8.. Now I "Iost" Volume button.. :silly: It mutes the sound but ingrease or degrease volume doesn't not work.. I think MCU update messed up.. Most probably tried with wrong version. With wrong ver lost sounds totally. Now with MCU ver 4.2.13.2501 got sounds back but volume button doesnt work.. Ideas?
[Android Head-Units] kaween:
What kind of front/facia design do you have ? 2 rotary buttons ? One ? Volume +/- buttons ?

What you can do in the mean time is check the volume +/- hardware assignment in the "hardware/Panel button learning" section. Maybe something went wrong there.

If need be, in the mean time, you could use that too to force sound +/- by assigning it to 2 other buttons : I did that during the time I had lost my correct MCU and was searching for the correct MCU : long press menu for volume +, long press menu for volume -.
[Android Head-Units] hellad:
In addition to given advices I can add following.

I've heard that some cache copy of original firmware exists. Sometimes it can be restored by forcing update WITHOUT ANY FILES in sdcard folder or on SDcard. I mean it works not during usual "system-general-update firmware" procedure but rather after Power+Reset (or same one) button press sequence.

It also was mentioned that original copy of firmware is stored in /dev/block/mmcblk0p7 partition on some devices. Thus, it can be extracted by command like dd if=/dev/block/mmcblk0p7 of=/mnt/sdcard/system.img bs=4096 from command prompt in Terminal application. Root access is needed in this case (or can try to enter without root rights the following command: run-as "john@tw-desktop.(5457)" command_here). The image obtained can be explored and compared with other versions of firmware.

That is very intersting !

It's sad my Russian is so bad and I can't read cyrillic at all (Polish decent here), but the stuff I sometimes read on the Russian forum is awesome. Guys replacing their analog TEF tuners with digital SI tuners for example ?! Looks like a geek-wonderland. :)

I do have a question for you : does anyone "over there" know who is able to alter/debug/upgrade system APK's ? I would very much like to see an updates radio APK (not talking about the skin/layout, really an updated version of it). Is there anyone out there who'd know something about stuff like that ?

Reason : bad RadioText+ decoding in the existing radio.apk. What I mean is this :

Although the AN21 can display RadioText info, it's far from flawless. I've noticed it fails a lot on most radio stations over here. It MUST be a bug in the decoding/display because this is what I see :

1) if the radiotext display buffer is filled up by a single, very long info line like (real example) : "Pure FM - Stromae - Meltdown 'feat Lorde Pusha TQ TIP and Haim", the AN21 will display such a string perfectly. But when if the song afterwards has a far smaller info line like "Pure FM - Oscar and the Wolf - Strange Entity" it will NOT be displayed. Also, stations that "flip info" during a song (alternative display of song/artist and Radio station) will NOT do so with the current radio APK. I'm 100% the info is broadcasted correctly, as my android phone's FM tuner decodes and displays the info correctly when used a reference during the test.

2) also, if a long text string is "stuck" like that, it will REMAIN stuck if you manually/seek another station. Only when you select a preset will the AN21 remove the old song info.

So it's not the matter IF the AN21 can decode Radio Text, nor if it can display this info : it can. But it clearly has issues doing so.

If this issue would ever be solved, I'd even pay money for it ! I've tried to contact the bigger sellers and Tonghai themselves, but I guess my mails are transfered to the garbarge bin the moment they are received. Considering the level of expertise I see/feel on the Russian forum, maybe that's a better place to ask this, but my language skills do not permit me to do this.
[Android Head-Units] safkafin:
Thanks for reply. I will test this on weekend. :fingers-crossed:

Got if fixed for good!! Finally I got everything working like I want it to.. I did a MCU update and that fixed it.

Btw, if someone faces similar issues after factory reset as me. Software installations wont work from Play market (error. Unknown error code during application install: "24" -> do factory reset again... Seems that although factory reset done something from previous installations stays and causes issues. Same issues with installing APK's. Errors when reinstalling software that has been previously installed.

Save radio chanels after factory reset

Hello

I need some help. I made a factory reset on my unit. Im still on 2.6.70. After the factory reset, my radio doesn't save the radio canels. I need to do a new search every time i have turned of the unit.

This question has probbably been answerd before, but I have trouble to search and get a good match. I think my bad English is the reason why i don't get any hit when i search.

Thanks!

/Niclas
[Android Head-Units] hellad:
You are rather right . Despite of the education system degradation over the last 20 years in Russia, we still have quite smart and enthusiastic guys ;) . They replace even CPU chip on motherboard instead of buying a new board.

I'd suggest you to read the following forum which was recently created especially for software development topics. If I'm not mistaken, guys discuss Radio functionality over there as well.
[Android Head-Units] kaween:
Actually, changing the cpu MST cpu board isn't that hard. I've done it myself, and at least one other forum member has done a "Frankenstein" too (replacing the working MST board from a dead mcu board to a revive a good mcu board with defective cpu). That's just a matter of having the right equipment, a bit of patience and detail for your work.

But the guy who replaced his analogue tuner for example, I was certainly impressed by that idea.

It's not so much the technical expertise I admire, but the willingness and eagerness of many people on that forum to think outside of the box, to dare things just to see if it's possible.

That has nothing to do with education level, but everything with personal drive, character and commitment of the forum members : things I've come to value much higher than any official degree or certification.

Lord knows, I know enough fully certified idiots over here who all make a lot more money than I do, but would be challenged to change a defective light bulb.

Give me a bunch of uncertified, eager, willing-to-fail-if-need-be-and-learn-along-the-way-while-willing-to-share people to work with anyday !

Thank you for the link. I'll be sure to have a good look at it. I hope you won't mind if I would have a question now and then if the stuff isn't clear to me.

[MENTION=4736782]kaween[/MENTION] what is the latest firmware ... I am running 2.8.8 anything new came out after 2.8.8? also does anyone has a radio APK that has RAD or maybe its ROD.. the APK I install from someone that mod it a few months ago does not show the artist and the radio stations and it does not has the option like sports, news, weather, and entertainment.. if anyone has the old radio.APK that has RAD or ROD please send me a link to it

Thanks in advance
[Android Head-Units] kaween:
Afaik, 2.9.3 Anstar should be the latest. Not tested it myself, running 2.8.8 here.

Not sure what you're meaning with RAD or ROD (part of filename maybe ?). The Radio APK that came with 2.8.8 shows RDS data (Radio statio, and artist/song). Only RadioText+ is iffy, but it has ALWAYS been iffy on each radio APK I've seen so far (from the old original ugly "presets on the left" to the version in 2.8.8 I running now. I've included a picture of the current version I'm using.

If need be, I can upload it tomorrow.
[Android Head-Units] majB:
Hi,

I have just bought a unit from them a few weeks ago. ( arrived in 3 days with DHL, I live in Holland)

My car is Skoda octavia and is pretty much a VW in many ways.

The unit has a can-bus and it turn on and off with the ignition switch.

The unit has Version 4.2.2 android, with the latest V2.9.3_20150112_1024X600_SYSTEM_DZSJ2 already installed.

Surprisingly is the bulit-in mic reasonably good.

I had HUIFEI unit before that, but the radio was horrible, blue-tooth and wifi problems. I am willing to sell it if I get a good price for it.

So till now I am satisfied with the unit.

I have contacted audiosources to see if I can update the unit to android 4.4, but as already said, they are not keen on giving updates, they told me if it is not broken don't fix it (I agree with them on this point).

I don't have i-phone, so I can not answer you questions about it. sorry about that!
[Android Head-Units] roystervi:
yes your right, I mean RDS if you can please upload a link
[Android Head-Units] majB:
Too bad to hear about this. Very frustrating indeed.

Did you look inside to see if the MB has a built in mSD

When I looked inside the unit ( mine does not have physical buttons also and no opening voor mini SD) I discoverd that it has one, but you can only reach it if you remove the cover.

I use it now for the navigation software. That means when I need to put another software, I must open the unit or use the usb or Airdroid to reach it from the outside.??
[Android Head-Units] svEmirKo:
I am also running the 2.8.8 but no RDS at all, some kind of chinese signs where the RDS should be.

Any idea?

On the new 2.9.3 there is only one file when updating the unit, while the other software there is always two, so my unit will not update with just one, is there anything different with the latest one with the update?!

Thx
[Android Head-Units] kaween:
And the lesson for today boys&girls is : when experimenting, always hold back a copy of the original. :D
[Android Head-Units] kaween:
The 2.9.3 is just the system files in that case, no mcu-or-whatever else. Shouldn't be reason for concern. I've not tested it myself mind you. Will have a look at it later this weekend.

As for "chinese sings where rds should be" : possibly your radio isn't set to the correct region. (general -> extra settings (code 123456) -> radio region)

---------- Post added at 09:53 AM ---------- Previous post was at 09:49 AM ----------

Heh ! Thanks for that picture. That's a totally different MCU layout than I'm used to. The position of the BT board for example.

You should be able to copy from any usb drive to that card without opening your unit when you're using something like Total Commander.
[Android Head-Units] wanxu:
Yeah! I was surprised there's a miniSD inside...
[Android Head-Units] svEmirKo:
Like I said, when updating the unit the same way I get only update start -- update end.

The region is also set to europe so I guess it is the right one, need to try other region I guess :rolleyes:

Thank You :good:
[Android Head-Units] kaween:
Historically speaking, the guys at Audiosources aren't the worst around. They'll fix stuff when need be.

And exactly that could be very intersting for us all. Exactly how does your radio app look like ? Does it look like the picture I previously posted ?

What I would like to know : does 2.9.3 have less issues with the RadioText string ? (the long info line underneath the station/rds name that you can see on my picture) ?

If this works correctly on your unit all the time, could you post that APK please ?

If it works "iffy" like on all radio apk's I've seen so far, maybe you can pick this up with Audiosources as a problem, as Audiosources is really one of the bigger players and probably has a larger "foot between the door" with Tonghai compared to a simple user like me.

PS : fijn om te horen dat de unit je bevalt. Je bent niet de eerste die zowel AN21 als Huifei heeft, en iedere keer lees ik diezelfde klachten van de Huifei. Kan dus geen toeval meer zijn.
[Android Head-Units] Josh22222:
Just wondering what options there are for music apps that can delete files on a micro sd?

I believe there is a issue with most apps not being able to see the files on a sd card. I would like to be able to edit/delete my playlists while I'm listening to them.

Thanks.
[Android Head-Units] kaween:
Rocket Player can. PowerAmp ... think so, not completly sure.
[Android Head-Units] kaween:
Hi there ! Look at post #6461, previous page. I made a picture of how my radio apk looks and acts.

My main beef with the AN21 has always been the iffy operation of the RadioText+ info. That picture shows you how it looks when it works correctly : the RDS data line shows (in this case) a part of the artist -normally it shows the station name-, the line underneath is RadioText+ where the complete dump of artist + song name is given.

The odd thing is : all Radio APK's I've had so far only show the RadioText info when it's either VERY long (like in this example), or completly static (like just the station name). On this radio station for example, the next song that was played was "Stones - Sympathy for the Devil", which didn't show up on the RadioText line at all.

I'm quite sure that second line DOES exist on your unit too, it just "never shows" becasue it will only under certain cirumstances : certainly if you radio APK looks like mine.

If you've got a GSM with a radio chip inside, just tune into the same station on your GSM and look how it acts : if it shows you more info than just the RDS data listening to the same radio station, and it doesn't show on your radio : THAT is the issue I'm talking about and would like to see rectified, and maybe if somebody like you can contact his seller with this issue, maybe it will get some attention and a solution.

Other than that, the AN21 design really is very nice I think. It does everything it must do rather well, radio reception and soundquality is good, and the BT sound quality using handsfree is very good (using an external mic here) even at 120km/h in a pretty loud Dacia Duster 4x4 Diesel. Your Octavia is a sea of silence compared to my car. :)

Anyhow, welcome to this side of the forum. May your unit serve you long and well. There's tons of info on this sadly very unstructured thread, ranging from hardware issues and solutions, extra cooling, how to open your unit withou leaving a trace of it, .... so if you've got a question, the answers' probably found here.

To grab the APK, you'd need to root your unit (Baidu), and then use a root-enabled file explorer (I tend to prefer Total Commander) to access and copy the APK from the unit's root\system directory onto an usb stick or whatever. But as you say you've never seen a second info line like I described and made a picture of, I'm quite sure it would be moot to do so at this point.

I would however find it interesting to know if -for example- your GSM radio app DOES show a RadioText line on the same station when your AN21 does not, and if you'd be so kind to pick this info up with Audiosources. Probably these Chinese sellers don't even know this is an issue in the first place, but I'm 100% sure this can not be so difficult to solve for those who have access to the APK's code.

PS : niet geschoten is altijd mis, en alvast een dikke "dank je" voor je moeite !

pumpkin 1din pure 4.1.1

Hi guys, wanted a newsmy vw 7 or 9 inch unit but in the end I decided to go with this one:

http://www.autopumpkin.com/car-dvd-p...bluetooth.html

Does anyone have this platform/model so I can get more info about modding? From this video ( https://www.youtube.com/watch?v=RmQJd9o8TCw ) I wasn't able to identify platform maker/MCU...could it be related to a specific one that you know so far?

Besides boot delay (about 15 sec), unlike dual os similar models from erisin for example which is a real frankenstein HU for me, can you point some disadvantages from the initial specs?

What is your opinion about it?

Thanks for your answers.

[MENTION=4736782]kaween[/MENTION]; is geen probleem ik houd je op de hoogte :).

Can you help me with this issue?

I have installed a reverse camera a few days ago. If the ignition is on (but not start the engine) and put the gear into reverse the camera works correctly, but if I start the engine and put the gear into reverse the camera view disapears and give me no video.

I have 4 wires in the socket; cam in, B+(12v), ground and reverse. The camera is connected to cam in, and its powers supply is connected to the reverse light. Connecting the reverse wire to 12v, does make the unit react, but shows black screen no cam view. Please help, I am lost there??

No FM Presets

Hello,

Using the v2.9.3 800x480 I had the red banner. I managed to swap the system file after rooting and solve that issue.

I still have the issue with FM/AM presets not holding. I do a long press to save and a dialog box pops up. I manually type

in something related to the station and click ok. That info is saved. I hit the button again and it just goes back to

87.5 which is blank/default. The preset info holds though. This problem existed even before the red banner repair.

My presets worked on version 2.8.10 until I went to 2.9.3. I did a bit of searching but only found a really old post.

Thanks Chris
[Android Head-Units] TheSSJ:
Had this problem too when using chris.r skinned radio app. The only thing that helped was switching back to the ugly radio app again, there it works flawlessly. What you can do is also (root is a pre-requisite):

1. Switch to old UI (if you don't have the apk I can upload it when I drive to work tomorrow)

2. Search and Save all stations

3. replace old radio apk with the new one, which should preserve all stations and show a good looking UI

That's what I did at least
[Android Head-Units] safkafin:
I got problem with external displays. I have two external displays connected and they got signal ok when using for example radio but when video turned on using MX player or Netflix the signal dissapears. I'm running UI 2.8.8 and updated MCU ver to 4.2.13-1-10-2101. Everything else is running smoothly at the moment.. Car is VW passat 3C.. How to choose exactly correct MCU??? :confused: Tried several ones (all VW versions) but all has some issues like volume buttons stop working or no audio or BT doesn't work.. :silly: If and when I get this solved I'm not gonna update MCU never again... Learned my lesson..

Edit: Just noticed that stock video player works on external displays, but for example MX player doesn't..

Any ideas? Might it be related to UI 2.8.8...? Is there any newer UI around which doesn' t have that "Un authorization UI" message..
[Android Head-Units] chris.r.r:
From my experience, the quality and upate frequency of Radiotext+ is dependent on the reception quality of the FM signal. It seems to me, that my unit only updates Radiotext+ if the rececption quality is excellent, because the better the reception quality is the more updates I get. My assumption is that in case of not optimal reception it cannot receive all bytes of the Radiotext without interruptions and therefore simply skips the update.

I agree, there seems to be a problem with the saving procedure in the original 2.8.3 radio APK, which I skinned --> not my fault :)

However, what works for me is that I drag and drop the station name to the station presets.

This is the procedure:

1. seek to your station

2. press long onto the station name displayed in the top of the unit (under the seek bar)

3. drag & drop the station to one of the station preset fields

4. station gets stored with the actual station name

Renaming of the stations causes some troubles. I haven't found a scheme yet, why or when it is not working.
[Android Head-Units] TheSSJ:
Hi,

sorry, I didn't mean to offend you by saying it is your fault - I already assumed that the error is located in the original apk :D

I took a look at the 4pda forum (with Google translate) and found apks from my base, which I will try out. Still they are not as good as your material design skins, but

maybe

remembering stations works out of the box.
