interesting issue with my unit... I use the SD card for my music and in order to use it, I have to eject it and then re-insert it to get the unit to recognize it after I power the unit up. this happens on .62 and .70

UPDATE!!! Turns out that if I use a 32g class 4 or lower the unit may or may not recognize it... My 16g class 10 card works every time and is recognized when i turn the unit on...

My first thoughts

Hi all

I stumbled across this page purely by accident while researching my Pioneer APP radio 2.

I decided to buy one and it arrived from China this morning and now fitted.

I cant tell you how different it is compared to the app radio.

That thing was so buggy with my android phone, snowy screen, disconnections and generally crap.

I have fitted the new one and everything just worked straight away, spotify, my 3g dongle, GPS.

The screen is also tons better.

I am chuffed so far for the £300 shipped to the UK cost being the app radio was £299

Ive hooked it up to the kids two monitors in the back so they can watch netflix and catchup tv, got the reversing camera working that I had from the old unit, wifi and bluetooth to my phone works with contacts.

So glad I found this page and makes an interesting read.

Next stop rooting, but unsure what advantages this will bring, any suggestions?

Cheers Dave

I think that unit could well be completely different, for example it lists the Android version as 4.0.4, not 4.1.1 like the AN-21 U. As well as all of the other hardware differences.
[Android Head-Units] sciallo:
Nothing?? Anyone? :confused:
[Android Head-Units] ransu:
I've used that module and it works just fine to store Google Music songs on the external SD.

My favorite xposed module is App Settings. Great for making apps like Nova and Play store, have bigger icons and text for easier readability.
[Android Head-Units] donaldta:
Well, I was not pointing out the other unit and suggesting it was a variation of the AN-21U but a new variation of generic Chinese head units. A different one seems to be popping up or being discovered every so often. It could be possible that the reason why chris.r.r cannot install the firmware updates from this thread is because it does not belong on his particular unit. So, I was checking with him which checks had he gone through to verify the identity is actually a variant of the AN-21U.

However, if he does have a AN-21U variant and it does not accept these updates then that is something that should be noted. There might be /system differences in the Universal variants with the vehicle specific units. Or, maybe the public key encryption code are different (for a reason) and the update process cannot be decrypted or applied to some of the vehicle specific variations.

Rolled back to 2.6.62

I tried the newest 2.6.70, but since it will not let me read the movies off the external SD card. I rolled back. hope they have a fix in the upcoming updates.

Great job BTW on all this research and information!!! Excellent :good::good::good::good::good:
[Android Head-Units] chris.r.r:
I was assuming that it's the same ;) but I checked it and seems to be the same unit... Mstar cedric3, Cortex A9 dual core

View attachment 2534870

Good point. Personally I could imagine that it is due to the encryption. The update procedure works exactly the same as for the generic one, with the only difference that it reboots, writes "Update Started" and immediately afterwards "Update End". So it's very likely that the unit simply uses another key. One obvious difference I noticed is that my unit only has VW options in the "Choose model" option, so no "generic" options.

i get today my new Dietz 6030 Can Bus with steering wheel Adapter,and have some problems.

The Adapter have 3 Cables for SWC:

Brown

Purple

Black

i get only select 2 signals in the Steering Wheel Setup but my car have 4 Buttons Vol+,vol- Prev and Next.

The setup takes only 2 to dictate from Yellow to Gray.

If i select the 3. Command then he takes off again a stored command:crying:

The next problem is that,my SWC Setup stores the instruction with no Problems (only 2 Stores) from yellow to gray and after that i pess End,

but later he makes no reaction when I press a key on my steering wheel.

This ist the Adapter cable which actually comes from my SWC adapter into the radio:

From my 3 Cables that i have work only the Brown Cable with Key-1 or Key 2 Cable.

The Purble Cable has 0,7 V but dont work with Key-1 or Key-2.

The Black Cable is Ground and it does not matter if i connect it with earth or not,

it only works with Brown Cable connect to KEY 1 or KEY 2.Have tried all variations:

Brown -KEY1 (Only 2 Command No Reaction after saving The SWC Commands)

Purple -Key-2 or KEY-1 (No Commands)

Brown -Key-2

need Help please:(
[Android Head-Units] PsychoMcSatan:
I think many of us are not quite as adventurous as you. And since my unit is stuck in a car in a cold, dark, Canadian garage, I've only tinkered out of necessity to fix deal-breaker issues. I've posted the couple things I've discovered that seemed unique, but otherwise I'm following in others' footsteps.

Thanks, by the way.
[Android Head-Units] jakejm79:
The UI also seems to be completely different to any other device out there, normally they are pretty much a standard Android experience but with a custom launcher, this appears to be completely different. Though I do question the need for a quad core processor in a headunit.
[Android Head-Units] sciallo:
As far as I can remember all options in the Choose model menu had VW in them... I have a generic 2 din...
[Android Head-Units] ransu:
I've noticed that when switching media controls over to 3rd party apps using the back button in the radio app, I always get that sound pop when an app starts or stops audio.. You can't even use voice search because it takes too long to pick up audio focus.

It doesn't happen when you still have controls being sent to the default apps.

Anyone have some insight on this?
[Android Head-Units] donaldta:
Most SWC Adapters have a way of changing the communication protocol used with a dip switch, rotary dial or jumpers. If you have the option to select between the different manufacturers on the Dietz then try selecting either Sony or Pioneer. They use analog (resistive to earth) signaling which should be compatible with the AN-21U. Some of the others like JVC, Alpine, Clarion and Kenwood actually use digital signaling which would not be compatible with either the Key 1 or 2 wires.

fixing GPS and .70 upgrade

Not sure if this was answered, but yes, you have to reset after flashing to .23. I had the same problem, and after I flashed .23, i went to .62. GPS failed once on me since then, but I rebooted the unit and it has been fine since, going on 4 days now,

Does .70 wipe all your apps on install from .62? It seems like every other upgrade brings you back to square one?
[Android Head-Units] donaldta:
You know what, in retrospect this seems very similar to one of the units that I mentioned back in Post #1278
[Android Head-Units] dvidal2fr:
hello,

I followed the procedure to be ROOT but when I run Android Terminal Emulator and I type:

su

rm / data / local.prop

he told me he can not find my file and radio idling since someone would have an idea.

thank you
[Android Head-Units] donaldta:
The text written in blue is what you would type:

$ [COLOR="RoyalBlue"]su[/COLOR]
# [COLOR="RoyalBlue"]rm /data/local.prop[/COLOR]

Notice there are less spaces than what you typed.
[Android Head-Units] dvidal2fr:
no I did not put spaces, it takes between rm /
[Android Head-Units] donaldta:
Well, if the file isn't there then there is nothing to worry about. Maybe double check if the file is there by issuing the following command.

# [COLOR="RoyalBlue"][B]ls /data[/B][/COLOR]

If the local.prop file is not there then type "exit" twice to get out of it.
[Android Head-Units] dvidal2fr:
thank you I'll try tomorrow to see if it works

thank you.

I have another problem with WASE it works fine except the sound there is no sound that someone that cares or is this normal
[Android Head-Units] djblaze852002:
Waze should have sound. If you read earlier in the thread you will see that in order for third party apps to have audio, you will first need to open a stock app (like the "Disc" app). When you turn on the radio next, it will open the last stock app you opened automatically. Try that...
[Android Head-Units] dvidal2fr:
thank you I'll test
[Android Head-Units] TOMMYX2:
thx i have a option with Jumpers:

here is the Manual

It is also necessary to put the JUMPER JP1 in the correct position for ALPINE and SONY

head units.

ok thx ,i try this method tomorrow:cool:
[Android Head-Units] fcortes626:
ok so my seller accepted to either exchange or refund the unit. i chose exchange since i already bought the squaretrade. he told me to ship it to on e of his partners that is located in the city next to mine so i only payed $9.75 via usps. Not sure if he is going to refund tht to me but that beats $90 for a new board or $80 to ship it directly to him.
[Android Head-Units] pgarrity18:
I think I figured it out. The problem is with the version of power amp I was using. The one on my phone worked ok. I think I had the trial version on the head unit with the unlocker added on. I thought that was how I got it on my phone too but when I installed the one on my phone to the stereo everything worked ok after that. Try the attached apt file and see if that works for you. Although I am not sure if it works and has some kind of license attached to it.
[Android Head-Units] pgarrity18:
This post is in regards to google gesture search, or even just contacts in general. Does anyone else have a desire to use gesture search to find contacts? I understand that the google phone app is nonexistent, but I do have tablet talk running. Either way it would be nice to do a gesture search for a contact and have their address right there to initiate navigation.

I have tried copying the db files from my phone and pasting them in the same folder in the stereo but gesture search still cannot find them, even after re-indexing. Only the apps are found. I have also tried dropping them in the gesture search folder with no luck.

One thing that almost worked was the "import contacts export contacts" app. I got the contacts to import but I do not know where, and they were searchable with gesture search. However the names did not make it in, only the phone numbers. The quality of what was imported was a complete mess so I deleted them all.

Has anyone had any luck with gesture search? Or even getting your contacts into the android side of the unit, where say a google app could locate them like they would on your phone?
[Android Head-Units] sciallo:
I don't know about gestures, but the contacts issue has come up in the past and never really got resolved or even discussed too much... our android build is missing the whole phone contacts and a few more services needed for apps like tablet talk and gesture search to work with contacts... from what I understand, it seems like it won't be as simple as installing a few missing apps either...
[Android Head-Units] donaldta:
Well, that's not exactly true. I only said that there could be a problem with the Contact's APK if it is using the System sharedUserID. The "System" sharedUserID is dependant on the ROM keystore and we cannot replace one package without also replacing all the of the files / packages which are signed with it.

However, I didn't realize that the time of that statement that Google's Contact app wasn't using it. It actually use the android.uid.shared (10010) which is a little more portable. You would still have to get rid of any apps that is using it but none of them should be tied down to the system. I even explained it better in Post #1360 but it doesn't seem anyone wanted to test it as only 1 person (I'm guessing that was you) downloaded the APKs and did not give any feedback.

As for syncing with other apps like Google Calendar, you just need the app and the sync adapter which can be found in this thread, "[G-Apps][GUIDE] Google Apps on the Kindle Fire -Getting Around the Update 11/30- View Single Post.
[Android Head-Units] sciallo:

stuck on 2.6.68

so i got my car back and the headunit is still on 2.6.68, confirmed gps wasnt working.

Backed up all my data and took a few goes but eventually got the firmware for 2.6.23 to flash - only when its done, settings still report ver 2.6.68.

Checked gps, looks like its working fine.

Flashed 2.6.23 again to same result. Then 2.6.70 to same result. 2.6.60 doesnt even flash - it says ''update start'' and then immediately ''update end'' like some others here before.

what gives?

Does anyone have a confirmed OBDII usb adapter working with torque?
[Android Head-Units] donaldta:
Only the one LANDU ODB2 BT provided from from the supplier will work and even then only with the included B-Scan software.

Apparently, I misread USB vs BT. Ignore this post. Nothing to see here.
[Android Head-Units] PsychoMcSatan:
USB does work, but not with all of the "clones" that are available. There's an eBay link earlier in this thread and I recently received mine and works fine. I already had another one that looks physically identical which wouldn't communicate with Torque.

Here's the eBay listing for that cheap adapter that appears to work okay:

http://www.ebay.com/itm/300905911932
[Android Head-Units] Mancubus99:
Does anyone have a link for .23 that they can share? The link I got from the OP is broken and I really need GPS working for this weekend. Thanks!
[Android Head-Units] donaldta:
Just remember: Make sure the dealer has a good return or exchange policy. If your happen to get a cheap or bad ODB2 adapter that doesn't communicate with your vehicle then I recommend that you return it for another. This is very common in the cheap Chinese ODB2 clones since there really there doesn't seem to be any quality control and in fact has been noted on Torque's wiki page.

Or, you can avoid the uncertainty and just get one from Scantools.net (which are also upgradeable).
[Android Head-Units] shavermcspud:
Thanks for the feedback donaldta & PsychoMcSatan

I will search on ebay uk, they all look the same, guess its time to take a gamble!

rooted via wlan.

Just rooted my unit today via wlan with unit installed already to car. As we have almost -20ºc here in Finland at the moment and I didn't want to freeze my self sitting in car. Everything went smoothly (although I didn't get Step 2 and had to configure rest with pc).

Next step would be updating the firmware version with .70 I'm just wondering what are the benefits and what are the downsides of upgrading?
[Android Head-Units] sciallo:
What are you running on now? Settings->About device
[Android Head-Units] amc_oldsarge:
WOW, what a first post. I will try this tomorrow.

Question for you, how do you get the Logitech K400 to work with your AN-21-U? I've tried a few 2.4 wireless keyboards with zero success.... I looked at this exact keyboard yesterday, but opted for this one GKM571R made by IOGear. Which of course, didn't work.....

People should really consider using VMLite so they can work on their car audio receiver from the comfort of their home. https://play.google.com/store/apps/details?id=com.vmlite.vncserver&hl=en This is an excellent app (great performance), well worth the $10 (US).
[Android Head-Units] squegie:
I'm surprised it didn't work for you. The receivers that come with these keyboards work like a standard USB HID. Android (or any PC) would just see it as a standard keyboard and mouse.

I simply plugged the little logitech receiver that came with the K400 into the usb cable on the front (though it should work as equally well on the back) and it works right away. If I want to use the on-screen keyboard, I just pull the receiver out.
[Android Head-Units] donaldta:
The only way I see it failing is if the USB voltage rail is over taxed so the receiver isn't getting enough power. A good test is to remove everything except the USB receiver for the HID keyboard / mouse and test it.

Additionally, if you want to use a soft keyboard along with a physical key, you can use Hacker's Keyboard then go into its settings and toggle "Show soft keyboard" so the text below it indicates, "Always". This will allow you to see its soft keyboard even while a physical keyboard is connected.
[Android Head-Units] jinny81:
So it looks like I'm stuck on 2.6.68, including crappy gps issues.

Now when I'm turning on my unit it tries to update the firmware without any doing on my pay to initiate it
[Android Head-Units] donaldta:
Great post! Though, you might take a look at FolderMount [root]. It does a kind of similar thing only using a graphical UI and it can be used on a per directory feature.
[Android Head-Units] safkafin:
Version 2.2.60 unit came with that.
[Android Head-Units] chris.r.r:
Yap, works... Worth the 2,99€ i would say ;) Thanks again...
[Android Head-Units] goolac:
Jin, you need to download .23 and extract it to an SD Card... There will be 11 files. Put the card in your receiver with the receiver OFF. Then hold down the Menu Button and press the Power Button (Volume Knob). The unit will start updating and this update will take nearly 6-10 Minutes!

When that is done you will have a virgin unit. Then repeat the procedure using the .62 update and STOP! (.68 and .70 have various issue that .62 does not. So for now .62 is considered STABLE)

The bad news... you will have to find and install GPS software.

The Good news.... your unit will be stable and ready to be upgraded to a version that is worthy of the next step.
[Android Head-Units] donaldta:
Exactly what are the .70 issues? I know the .68 version is known to cause problems with the GPS if you use the "complete" version that was Frankensteined by [MENTION=1915855]KID52[/MENTION]. However, according to [MENTION=304291]Black6spdZ[/MENTION] in Post #1619, he was able to use the "partial" (unmodified from the manufacturer) and update to .68 without any problems.

Boot Animation troubles

Hello, I have a quick question. I created a boot animation for this unit and tested it in boot animation factory - it seems to run fine there. I am having trouble figuring out where to install it on this unit and how to get it to work. I tried putting the zip folder in system/media, but that did nothing. So, I searched for the boot animations that come with the head unit using root explorer. The path that they seem to use is /etc/bootanimation. After some trial and error, I was able to get the zip folder to copy over correctly and completely. This allowed me to see the option to select it in the boot animation app that comes stock with the unit. However, when I select it as the boot animation and restart the unit, I only get a black screen until the unit finishes booting. What am I missing?
[Android Head-Units] pgarrity18:
So I tried the calendar app and it didm;t work for me. Calendar unexpectedly stopped every time I opened it. When I install the calendar from google play, it opens, but does't let me sign into my google account, so the calendar is empty. This isn;t much of a concern for me, as I don;t need the calendar, but I figured I would share my experience.

As for the contacts, I will definitely give it a shot at some point, but I have some other issues I want to focus on in the meantime. I'll put tho one on hold. Thanks for the info.
[Android Head-Units] donaldta:
Did you install the GoogleCalendarSyncAdapter.apk and enable the calendar in your Account & Keyboard control panel of the Settings app? The Calendar app by itself does not facilitate the sync. The Sync Adapters is what allows you to sync the app with your Google Account and that is setup in the Settings app.
[Android Head-Units] pgarrity18:
I meant to reply a second time to this thread a while back...

My goal is to have Poweramp begin playing once I open the app (instead of starting in a pause condition). When I close the app I want it to keep playing, so I simply did not apply the second task you suggested. The problem is that when I bring the app up again (was playing in the background) it pauses. I thought the play option would be different from the play/pause and it would take care of this issue, but apparently not. Same thing happens on my Galaxy Note 2 running 4.3, so I assume this isn't specific to the unit.

Does anyone have any suggestions using either llama or tasker to make the app play when opened and when opened again simply continue to play and not pause? I suspect there is a simple workaround that I am not thinking of.

---------- Post added at 10:45 AM ---------- Previous post was at 10:43 AM ----------

I did not enable the calendar in my Account and Keyboard control panel. That must have been the problem.

---------- Post added at 11:06 AM ---------- Previous post was at 10:45 AM ----------

I am having a serious issue with sound quality and I am not sure if it is a bad connection or something with the software. When I start up my truck everything sounds great. As good or better than my stock radio. Maybe 5-10 minutes into driving, everything goes to crap. Pretty sure it has to do with my amplifier/subwoofer only, as the bass picks up a lot of noise. If I use the equalizer to remove power to the sub, the noise goes away, but no bass and sounds horrible.

I can't understand why it sounds good for the first 5 minutes. Everyone experiences that "pop" sound in the sub when switching media apps, which makes me think it might have something to do with the unit itself.

I know the wiring is set up correctly, I double checked it yesterday and re-wired the amplifier signal connection. I feel good about the connection, although I may try to bypass the harness altogether as I cannot guarantee the connection is solid inside the harness. It could be something as simple as the flimsy connection between the harness and the stereo but until I troubleshoot further I can only speculate.

Is anyone else not happy with the sound output? Specifically at low frequency? Has anyone else experienced this condition where the music sounds great at first, then get's worse after 5-10 minutes?

Perhaps the unit is poorly grounded, and some inductance is building up somewhere that prevents the noise from joining the signal at first? Obviously I am just guessing at this point.

Startup Delays

Pretty sure I've not seen this question yet.....

Fairly often, on startup, the unit just hangs but plays the audio of the last source as it should. Either black screen with a few icons displayed or the last audio app loaded but no control. After about 1 minute(in addition to normal startup time) or so everything just takes off and starts running. I do have a 32gb card installed. Thought maybe it was tied up scanning the card, but one would think it would hang every time, which it does not. Both of my units do this. I loved these things so much I put one in every vehicle. Both of my units are at .62 and fully updated on all Google Play apps.
