Hi!

Well, I had this problem. I did what user merit40 said:

Install version 2.6.60-2, then install version 2.6.62 and finally version 2.6.70. Just apply the updates, don't reset the configurations.

This fixed for me.
[Android Head-Units] mad212:
I am rooted. I'll check the MCU after work.
[Android Head-Units] mad212:
I'll give this a shot when I get some time. is this for the live wallpaper issue or the radio station program issue? Updating firmwares doesn't wipe apps does it?
[Android Head-Units] hidraq:
I solve this problem with install audio capacitor on 1F capacity on power line(capacitor connected to subwoofer amplifier and AN-21U headunit), when engine is starting. no power shutting. unit is perfectly working! I am happy:laugh
[Android Head-Units] avgaz:
Who ever does the option "Shutdown delay" if so what is your version of MCU just as I did not not want to work on firmware 77 ?
[Android Head-Units] PsychoMcSatan:
I'd never tried the capacitor idea as I'd read on another forum that it's very hit and miss and could be affected by what else is connected between the battery and your head unit. Are you using just one capacitor, or one on the sub and another on the head unit?
[Android Head-Units] terciofilho:
This is for the Radio not saving favorites.
[Android Head-Units] hidraq:
I put the fuse before capacitor and after him, I have is one capacitor on the head unit and the amplifier

radio on startup

Can someone please help me with a minor issue on my 4.1 player?

I've done a search, and this issue was touched on but not directly addressed (that I could find, anyways). I installed my unit originally with a constant power connect (as that's what's in the wiring harness for my VW Jetta), but swapped it over to a switched power line from the fuse box so it would turn on and off with the ignition. But now whenever I turn it on, it defaults to the radio on channel 87.5 (ie, shrill static). It didn't do this when I was connected via the constant power, but I had to turn it on and off using the power button.

I guess i can put Tasker on and have it automatically go to the Aux or something, but that wouldnt' kick in until Android boots up.

Does anyone have any recommendations? Did I wire it wrong, or is it a software issue?

Switch launchers

hey PsychoMcSatan much like yourself i prefer the small icons of the 2.6.62 launcher and i've recently updated to 2.6.77, (in hopes of fixing an ongoing issue with my disc drive). anyway i saw that you had successfully pasted in the old launcher and decided to give it a try using the file provided by donaldta. i tried to use the ES file app to paste that file over the exiting version in system/app. when i looked in the folder it showed as empty however when i copied donaldta's file from my sd card and then tried to paste it in system/app i got a message saying that the file already existed and asking if i wanted to overwrite it. i clicked ok expecting to get the old launcher back. instead it told me that the path was not not a valid directory. i thought that maybe i needed SU privileges to make the change so i rooted the unit and tried again.

anyhow to make a long story short i'm pretty new to android and i'm not sure what i did wrong or didn't do right. can you please tell me how you got it to overwrite the newer launcher. thanks.

Anyone here running the latest 2.6.77 on the VW version? any issues??
[Android Head-Units] avgaz:
I have installed on VW
[Android Head-Units] blankers:
I don't know specifically about this unit...but, you normally have 2 wires coming from the head unit. Yellow and red. The yellow (acc) wire needs to go to ignition power (on and off with key) and the the red goes to constant power. If you connect both to ignition power it will work but it won't have a constant supply to save the radio stations.

Hope this is clear......:)
[Android Head-Units] stanjkof:
Giving those chinese units full battery access this way is a terrible mistake. They should be set to work only via key ACC position.

I have ZX803

Mine was connected so it starts only with ACC and key inside, and even then it managed to start itself without the key and when the car was locked. I guess that canbus adapter box makes it possible, and it fuzzes up car's cpu so it doesn't cut the power as it should.

In 3 days I will have that option disabled at may car specialist.

It will start the power and cut it out completely with the key. Do you think I can expect some filesystem problems with cutting the power without shutting the android down first? I believe ita does that anyway sometimes (gives me that code 1 on screen while booting).

Sygic SD Card Access Denied

I had this problem and was able to resolve it by deleting the /sdcard/sygic folder and putting back a copy of the original /sygic folder.

In order to erase the folder I needed to use terminal emulator to do the following:

su root

cd /sdcard

chmod -R 777 ./sygic

rm -rf ./sygic

Fortunately I had a copy of the original sygic folder because I tried to install TomTom when I first started the unit and needed the room on the /sdcard folder. I copied the folder back and the original sygic worked!

The funny thing is that when I erased the sygic folder the first time to make room for TomTom (which didn't pick up my GPS btw) I didn't have to change folder permissions. I'm assuming sygic pushed an update through Google Play that buggered the factory (illegal) copy, and then locked the folder. Sneaky!

We'll have to see how long this will last. Hope this helps someone.
[Android Head-Units] PsychoMcSatan:
I don't have an Android device handy, but I believe ES Explorer has a setting(s) that allow root access and write access. I'm pretty sure I had the same issue as you till I fiddled with settings in ES Explorer.

I ended up installing a 3rd party launcher (Nova Launcher) which works fine and allows for nice customization.

Problems with Bluetooth Samsung S4

HI!

Maybe i did a big Mistake *lol

I updated the Unti to latest Firmware here *.77

I also updated my Samsung 9505 S4 at latest Firmware.

Now i have the Problem that the Phone see the Head Unit, i can pair it but at the Head Unit mit S4 not apears in the List.

Its not possible to go Contacts or Phonebook.

At Phone all looks fine, it shows its paired with the Radio.

Any Ideas what i can do?

Somebody similar Problems with Bluetooth with the latest Firmware?
[Android Head-Units] PsychoMcSatan:
I think the issue is with the MCU. I see that about a month ago you had issues with your knobs working backwards and it was fixed when you wrote:

I had the same issue so I applied that MCU, but later found that my bluetooth was doing exactly what you are now describing. I think we have the same model (two knobs, volume on right) and the only way I was able to fix it was to go back to an MCU that has the knobs working backwards: 4.2.5-7-10-2501.

Actually, I'm now on 4.2.7-7-10-2501 which is included with the .77 system files. Unfortunately it still has the issue with the knobs.
[Android Head-Units] B.Stromberg:
Yes you are right same Models!

My Phone worked before with BT. ( with already restored MCU at Version x.70 like in my Post you quoted )

Silly Problem is that i cant say whats the real Issue

I stupidly updated both Devices.

I know Samsung had changed many at BT Profiles in the new Firmware.

I now also have 2 VW Versions in the Model choose Menu. But to be honest i am scared to choose one *lol*

Thats why i ask here first.

Does anybody has a 9505 with 4.4.2 Version XXUFNB8 running with the Unit?
[Android Head-Units] ThePapabear:
That´s exactly the same problem i had with my unit (at least 3 guys with the exact same unit). Knobs worked correct with your mentioned MCU, but Bluetooth failed (worked for one time, then no more).

I am also on an MCU with backwards working knobs, but Bluetooth is working again.

Choosing an Model changed something with the MCU, but nothing on how knobs are working and Bluetooth keeps working.
[Android Head-Units] shadowbob:
Hey guys!

Just installed this head unit into my car, but have problems for connecting steering wheel controls. Understood that there are two wires going out from head unit, which I can teach for different actions. But what wires I should plug-in with going from my car? There is one paired ISO connector, which I've already connected with AN-21 and 1 toyota 24-pin connector, which left un-connected, as I don't know what for it is.

The car is Camry 2007. Did someone have any info for this case?

Please....looking forward for your feedback, as I don't have any smart electric specialists in my small town.
[Android Head-Units] hidraq:
You can write to my PM in russian, and i help you.
[Android Head-Units] B.Stromberg:
Ok many thanks for the Tip with the MCU again.

It was my last Thought that the MCU causes that Issue coz i didnt change Model or else bei updating to x.77

Finaly for me worked the 4.2.7-8-30-E501.

Phone is recognized by BT again and Phonebook etc. running.

Silly Sidekick btw, was that Root was gone. I am not 100% sure but i think i rooted the x.77 after flashing.

I recognized by starting Root Explorer by getting an Error Message that the Device isnt rooted.

Anyway, now it works again fine, Volume also not mirrored.

I attach that File what works good to me if maybe somebody has same Issues again.

I also use the "old" sort Phonebook File. Even that works fine but i really wish somebody could modify that file that Names sorted by Lastname and not by Firstname.

Plz, how to remove the factory widget on the home screen?
[Android Head-Units] Prdie:
If you mean the icons that are used for launching Navi/Radio etc.., then you can easily get rid of them by installing another Launcher from PlayStore. I'm for example using Launcher 8 Pro to get a Windows 8 look (or ADW or Nova Launcher). After the install press Home and choose the new launcher as default. Happy customizing.
[Android Head-Units] trt131:
Is there any way of displaying album covers in the stock media player.

I am also using Poweramp but its a pain not having it come on as soon as the unit is switched on if it was the last function used whe switched off.
[Android Head-Units] B.Stromberg:
sh.t!

I have to take back my Comments out of my Thread before.

After restarting the Unit after one day BT Connection again was gone.........

Its true, BT only works with the Mirrored MCU Version till now :(

I will try the other Versions if i have time.......

Sorry for beeing too fast to think it works with that MCU Version i attached
[Android Head-Units] PsychoMcSatan:
So I tried that MCU (4.2.7-8-30-E501) again to fix the knobs to turn the right way, but like you, bluetooth stops working after a reboot. So I reapplied 4.2.7-7-10-2501, but still nothing. Rebooted a couple times and still nothing. I ended up having to go through the steps I went through last time to fix it:

First apply 4.2.7-1-10-2101.

Check bluetooth and reboot again.

If bluetooth is still working after reboot, apply 4.2.7-7-10-2501.

Not sure why you need to go with 2101 first, but I just couldn't get it to work with going straight to 2501. You likely wouldn't want to stay with 2101 as the knobs don't work at all with that one.

I don't mean to complicate this more, but another weird thing is that last time I did this, I applied 2101, and then did a model choose (picked the top on the list) and it put me on 2501. However, this time I tried the same thing, but it put on 6501 which has backwards knobs and broken bluetooth.

So long story short, there seems to be a little randomness going on here. My guess is that the MCU flashing software may be a a little buggy so I've decided to quit playing with it.
[Android Head-Units] B.Stromberg:
To me Model choose bring back the BT.

Silly!

Hopefully somebody can decode those MCU Files to fix the Mirrored Knob........

Hello everyone.

I bought WiFi OBD-adapter and now have a problem: internet via 3G modem not working when OBD adapter is connected to the radio (OBD-adapter seems to android as "wifi hotspot", android trying to connect internet via this hotspot).

Suggestions for a new buyer

Hi! I just discovered this, and I am very interested in ordering one. I have scanned through a lot of the 200+ pages and looked for info, but was hoping someone could summarize any of the issues before I buy.

It looks like the latest version of the software has some BT troubles, is that true? Is there a recommended version?

Does anyone has a specific eBay (or other) link to a solid unit? I want 7" screen + capacitive touch, fastest CPU/GPU if possible.

Any issues with brightness or glare?

Any trouble with 3G (AT&T in the US)?

Does it have satellite reception?

I have a Prius C and would like to use the column controls. Will that work?

Thanks for any info, I appreciate it.
[Android Head-Units] shadowmike:
My 6.2" unit has no issues on newest firmware

No brightness or glare issues unless direct su light is shining on the screen.

I don't use a 3g dongle, I tether my phone to my radio with WiFi

My unit started forgetting my selected live wallpaper. Each time I start my car the unit reverts to default wallpaper (the winter screen). Not sure why, I have not changed anything on the unit / setup for months. I have to then go and change the wallpaper each time which is annoying.

Hey all!

Can you pls give me some tips on blw:

1. How can I make music playing while going reverse -> using rare camera. Music just stopps while proceeding backwards.

2. After rooting I have annoing notifications that SU is out of date and needs to be updated. How can I turn off these notifications?

3. After switching off ignition and taking key away unit still has some power for few seconds. Is it possible to prolongate this time till 5-10 minutes?

Thanks!
[Android Head-Units] PsychoMcSatan:
1. Under settings->sound

2. I don't think your rooting completed successfully. Try going through the process again.,

3. That delay is likely your car maintaining accessory power. Currently there doesn't seem to be a way to keep the radio on after accessory power is dropped. There is an option for this in the latest .77 system software, but it doesn't appear to work.

As I've posted before, you can maintain accessory power with one of these: http://www.cope-eng.com/powertamerVS.pdf

i'm assuming you have the wallpaper moved to SD to save space. If this is done, it takes a few seconds for the OS to mount your SD internal storage. As it needs SOMETHING to boot to, if the SD is not mounted yet for your live wallpaper, it will default to the backup image, which happens to be the snow landscape.

Re-installing it would have placed it back to device memory btw.

Is there any thing that needs to be done to get tasker to start on boot? I'm running the latest firmware. But tasker wouldn't start on its own.

I've searched all over the place it seems at least in this thread it works for some ppl and not for others
