1) I'm not sure. I think they work via CANBUS interface. If your car has CANBUS and that's how the steering wheel controls operate, it should work, in theory. My car is not CANBUS so I really don't see how the wheel controls could work.

2) Don't know - if anybody else knows, please let us know...

3) That's a function of your factory car electrical system. All cars should have a +12V circuit for accessories or the radio specifically, when the key is set to the first position or the engine is powered on.
[Android Head-Units] brons2:
I'm looking to replace my factory head unit. I thought it would be cool to have an Android HU. I'm a little disappointed how expensive these things are still. They seem to use lower end components and older versions of Android. I would be ok paying $200-$300 if they had the latest Android and better components with some sort of reasonable support. I'm not saying it has to have the same capabilities as the latest Galaxy S5 or whatever. My expectation is that it would at least have the same capabilities as a prior-gen Nexus 7, which they don't.

I think it's a pass for me, personally, when you can get a low end Pioneer double DIN deck with good reviews for under $100 shipped that has bluetooth handsfree and audio integration with your phone. I'll just keep doing navigation on my phone, or get a 7" tablet to satisfy my navigation needs.
[Android Head-Units] ZexGX:
I'd like to see a low end $100 double DIN deck that can do everything that Android headunits can do.
[Android Head-Units] m00n13:
1. If you have resistive steering wheel controls it works without any additional purchase. And I don't think the Giulietta uses CANBUS so you should be safe

2. You can use both Google now and Google maps. OK Google works only partly, i.e. you have to first launch Google Now or Google Search. However the built-in mic is pretty lame so I would not rely on voice commands

3. That's pretty much how it works by default

Agreed. And more. I replaced my 2DIN Pioneer with this unit and I don't regret it - radio is way better, the music player is at par but on this unit you have an actual display.

Don't get me wrong, it still is a crappy piece of hardware if you compare it to today's technology but it's many times better than what car manufacturers or established OEMs try to sell you for much more. I had a Parrot Asteroid Smart - worst device ever made by Parrot and much more expensive.
[Android Head-Units] kaween:
Indeed, the whole point of it is : you won't find it. With all the shortcomings, bugs, oddities included, these devices still are uncomparably more versatile and thus even when "item x" doesn't work like you want, you can seek other SOFTWARE solutions to alter the unit's behavior. Try that with any low cost 2din or even high-end-brand-closed-system unit. You all know you'll come up empty in that search.

If (and by no means this is said in a condescendingly manner) anyone is looking for a "out-of-box-ready-to-run" device, these android units are indeed not meant for you. If you like to experiment and put some time in them in a search got have a personalized device that is tailored to your own needs, there's no alternative.

[MENTION=1759114]ZexGX[/MENTION] : I was looking at the device you chose, and something strikes me as odd. In the sellers' pictures, the device is said to have a 178x100 front size. However, when I look at the pictures of the unit from behind, it's clear that the front actually sticks out on all sides in relation to the metal part of the unit. But the metal part SHOULD be roughtly 180x100 to be 2din, so how on earth can the front size measurement of 178x100 be correct ? I've asked the seller this question, but I got a "I measured it myself, I'm sure it's correct" type of answer. But in all honesty, I don't really believe them. A couple of other answers I got from them bugged me too, for example they stated they "could change the color of the leds for their customers depeniding on their needs", but I see the "color" application on the video that allows color button choice.

They also state the unit has NO capability of connecting a front camera, only a DVR camera. But on the backside, there's a clear "AUX" video input to be seen, AND a "CAMERA" input (rear cam). So why would the unit not allow a second normal cam then ?

Would you mind answering a couple of questions about the technical side of the unit once you receive it ? Because the sellers' answers are somewhat ... doubtful. It's either that, or the pictures they've posted are wrong and only the front picture of the unit is correct.

PS : I got to speak to Sherry now. The sizes in the picture are WRONG. She kept insisting the picture of the front size 178x100 was correct, but on the rear view pictures of the unit, it's clear that the front side sticks out in all directions. As the unit itself must be 178x100 to be 2din, that simply didn't make any sense.

She confirmed now the front side is BIGGER than the 178x100 they state in the picture. So beware unless you have a large enough dashboard opening or do not mind substantial cutting of your dashboard because it looks more like 185x105 at the very least.

FOR ALL those having eq problems that have the non dvd version I have, I've managed to find the best mcu for it and it's the right one for that model. Sounds excellent now as well and no eq reset! All I did is downgrade my mcu to....

4.2.7-1-10-2010

Let us know how it goes if anyone else uses this mcu.

Seems like every week something else goes wrong.

Thank you.

[Android Head-Units] Journeyman91:
Thanks for ur answers guys. So apparently the Alfa Giulietta HAS a canbus interface for steering wheel button controls.

Is there a generic canbus control unit I can buy to use with the android head units? Only ones I see are specific ones for Kenwood e.g. ....

Many thanks!
[Android Head-Units] Miwer:
I've been following this thread for a long time, and I have not heard of an official "full format" ROM.

However, I have seen numerous mentions of 2.6.60 fixing various problems for others. This ROM also contains more update files than the others do, so I suspect it touches more partitions, resetting various stuff.

I have not tried it myself, it's just what I've read here.

So try and install 2.6.60 and upgrade again from there.

/Miwer
[Android Head-Units] bjamerson:
I've seen the rom mentioned but never where to grab it. So now I have come complete circle, unit came with 2.6.60.

Hello,

Excuse me for my bad English, I am French.

I have a Peugeot 308 with canbus

I have buy this car player : www dot aliexpress dot com/item/Pure-Android-Automobiles-GPS-Navigation-DVD-Multimedia-Player-Touch-Screen-Radio-Video-Audio-Bluetooth-Peugeot-308/2013824234.html

I think it is an an-21 u model. The characteristics are:

Version android 4.2.2

MCU version 4.3.3-11-922-4501

System version 2.7.32

I had buy a complement for a can bus decoder but Steering wheel control don't work.

The seller said me to reselect the model (408) in user settings but it's still don't work.

Have you an idea and a solution for my problem ?

Thanks

White Screen of Death

I just installed the unit today. Finished the installation, booted up great. Tested the DVD, CD, Radio, etc.. Was a happy camper until I decided to go to the extra settings menu (passcode: 123456) and changed the boot logo to Nissan. After I made this change and did the restart all I am getting is the white screen and static in the speakers. I can mute the sound and adjust the volume, just none of the other buttons work. I've got a DVD in the drive as well :( that I can't eject due to the boot stopping on this white screen. I'm assuming the boot graphic is corrupted and my culprit, but then again it could just be a coincidence.

I've seen others experience this issue and am wondering what this "typically" is for those of you that may be more experienced with this unit. I've tried taking the latest firmware and extracting the rar to an empty 4gb FAT32 formatted MicroSD card. It doesn't appear to be reading the SD card upon booting the unit. I've tried holding reset+home+volume (release reset) and it won't pickup the contents of the MicroSD to start performing the update. Does anyone know if the update can be ran from the USB port using a flash drive or if there is a way to sideload this unit?

It's a bit of a bummer that my whole experience lasted a good hour. It's a bigger bummer that I ordered the unit from China and any type of exchanges will undoubtedly take significant time and $.

I certainly hope there's something else I can try.

[Android Head-Units] psykojezus:
i was actually thinking that as different faceplates for this model show the card on either side. The GPS slot doesn't release in a similar fashion (it's on the right side, doesn't feel springy?). Think I can pull it with needle nose? I'll try when I can.
[Android Head-Units] hashman:
Hi mate

I bought mine for the peugeot 508 from same site but different seller

The problem is most likely in the canbus supplied

Is it a black one or a see-through maroon/red/brownish one?

The black ones are for wince models that some sellers are sending with abdroid units. They will NOT work

So I've had this unit for about 2 weeks now. Here are a few questions I have,

I'm on 4.1.1

1- Is there a way to download music from the CD-ROM into an external hard drive using the unit only?

2- It's easy to store music from Google Play by downloading it. Is it possible to download it to external drive?

3- Is there a way to record live radio?
[Android Head-Units] psykojezus:
Does anyone have the SD slot on the right side of the unit filled with a hard piece of plastic? I don't know what it is if anything and if it's safe to pull out. It certainly doesn't pop out like an SD card and is almost flush with the radio.

Here is the unit I have.

[Android Head-Units] kaween:
That means your droid board is dead. The functionality of volume control originates from the mcu and will work independantly of the android fuctions. The other buttons do _not_ as they are bound at some level to an Android function in the background.

The MCU still runs, the androidboard does not. In such case, recovery is -I fear- impossible with the AN21-board and the only thing possible is repair by the seller or replacement of the mainboard.

In my case, I could get my unit to boot sometimes by pulling power for a longer period of time, or even by putting the unit in a freezer for some time.

The "plastic part" : on most AN21's, only 1 SD slot is usable. But the companies use a generic front that allows 2 SD slots for boards that support that functionality. Pulling that plastic piece ... shouldn't damage nor solve anything.
[Android Head-Units] eldowan:
I've been following this thread for a while now, and was really interested in the possible new model that was posted a few pages back, with the 7" screen.

However, it seems that many of the units are coming with horrible build quality and I'm quite hesitant to spend a few hundred dollars on a big POS and not have car audio at the same time.

Are these units really worth it, or are they more a crap shoot than a reliable product?
[Android Head-Units] hashman:
See both that i got with my 508 unit

I have sent a message to the seller but it is mid-automn festival in China. I don't know when I will receive an answer.

[Android Head-Units] ZexGX:
The LED color I am not too concerned with. It should work for my needs. As for the camera, I am guessing it does allow for a second normal camera but in the unit will be labeled as a generic AUX input and not specific to a Camera label in the GUI.

Not a problem. Will do.

That's unfortunate. I will need to do a test fit and see what will need to be done to make it fit if it is indeed larger. In my case, I am guessing a custom radio bezel, which is not too much of a problem for my car, as it is a simple flat shape with cutouts (and I have a laser engraver, so that helps). I'll be sure to post an update in this thread.
[Android Head-Units] psykojezus:
Thanks kaween. I won't be sitting out in the blazing heat repeatedly trying to update the firmware any more and will just wait to hear back from the vendor. Considering the time involved with exchange do you know where a board for the AN21 can be purchased?

[Android Head-Units] kaween:
Aw, And I seriously loved that movie. Kid at heart, this one. Toothless reminds me of my black cat.

I've ordered a board on Aliexpress like some others have done before me. AFAIK, that's about the only seller that sells these boards as spare parts.

h t t p :// www.aliexpress.com/item/Android-4-1-Motherboard/1623235987.html

But I wouldn't proceed with that route till you have absolutly no other choice.

If it's really that hot over there, you could try this :

* uncouple the power to the radio system or better, take it out of the car completly.

* if you have a stable 12V supply capable of drawing 3Amp on 12V, you can make a simple testrig to play with the unit outside of the car. If the unit is defective, you'll have to disassemble it anyway, don't you ?

* let the unit cool down. Put it in the fridge for half an hour if need be (7°C Celsius is good enough). Try to power it up.

When it does, enter the extra settings and alter the fan policy to "open" so the fan runs all of the time if that isn't the case yet.

See if it make any difference for you, but so far, what you write looks very much like what I've had on my unit.

Who was your seller if I may ask ?
[Android Head-Units] psykojezus:
I see the board is for $150, nearly the cost of the head unit. I purchased the unit for $199 w/ DHL free shipping from China on eBay from we_styles. It delivered in less than 3 days from Hong Kong to Tennessee. For this I am highly impressed with DHL speedy delivery but for the radio, not so much.

I put it in the bag and actually put it in the freezer, I didn't want to take the unit apart to avoid "voiding" the warranty but was able to take the faceplate off. I didn't see any burst capacitors or anything else that seemed off. I did adjust the fan policy to low before the unit "died" and when I turn the unit on the fan does come on. I rebooted it several times, and was having a blast with it. It was only after changing the boot logo from extra settings to "Nissan" that it wouldn't restart. This is why I'm wondering if there is a fix that doesn't require replacing the board but everything I'm seeing in this thread suggests that if the screen is white and the mcu is functioning but won't allow me to run the update off the SD that the android board is dead. Maybe there is a connector loose somewhere.

I'll send out an update for better or for worse. It's a shame that these units are hit or miss because the concept is everything we would want out of a radio in the car. It's a powerhouse of a head unit that does nearly anything we could want.

i scrounged this thread trying to find fellow VW "users" but it seems there are not many.

[Android Head-Units] Skratchuk:
Can anyone that has this unit (see pic)

confirm what mcu came with the unit originally?

Is anyone else having problem with 3rd party apps with this unit as well, i have tried changing priority but nothing seems to get it working.
[Android Head-Units] jpapadami:
Mine came with X.X.X-1-10-2101. The MCU version will depend on firmware version that was installed on the unit before it was shipped. What version did yours come with?
[Android Head-Units] Skratchuk:
Thanks for that, i think it came with android-4.1-2.6.98 seems like such a long time ago now, i wish i wrote it down!

Anyway i have downgraded my mcu to 4.2.9-1-10-2101 as the eq resetting was really getting on my nerves, since doing so the unit sounds great but now i have the no sound on 3rd party apps again even after selecting sound priority.

Im thinking about a complete reset and trying again. You have any problems mate?
[Android Head-Units] jpapadami:
No, I have never had problems with sound priority or the eq. If you do plan on doing a complete reset, there was a firmware posted in post #4403 that reformats and performs a factory reset. You might want to try it.
[Android Head-Units] psykojezus:
I'm dead in the water it seems. Tried the chilling technique, just a white screen. Since the mainbkard costs almost as much as the unit I'm thinking on any replacing. Does anyone know if the WIN CE variant can't be upgraded to android? Hardware seems the same.
[Android Head-Units] Skratchuk:
I have reset it completely now, what is your mcu and version please?
[Android Head-Units] jpapadami:
I edited my post right after you sent out the reply :). Look at post #4403 for the format firmware in case you need it. Otherwise I'm using firmware 2.7.35. My MCU is from version 2.7.38, but had to downgrade because you can't root it. I'm currently at 4.3.7-1-10-210101. Not sure why there is an extra 01 at the end of the MCU but if you update to 2.7.35, there should be a firmware with X.X.X-1-10-2101
[Android Head-Units] Skratchuk:
Ah ok i used the 2.6.60 method, i'll try that as well thanks for that.Im surprised you haven't had no eq resetting problems. Could you upload the mcu for me please?

I had trouble fully rooting 2.7.35 but will try again. I saw on 4pda that there is a modded 2.7.38 https://yadi.sk/d/Xu7RYrApb9ouL i tried it out and quite liked the launcher and icons, it didn't have the unauthorized message on it either. I didn't try to root it so no idea if its possible.
[Android Head-Units] jpapadami:
In order to root 2.7.35 you need to use the Baidu Russian version. There was some problem that when you update the binaries from SuperUser you loose root. But the workaround is to install the baidu russian version and root, then install SuperUser and update binaries, reboot the device, and finally remove Baidu. You'll also need to replace the tw.services apk with a modded one from here to remove the UI unauthorized message.

When I get home I can upload the 2.7.38 firmware MCUs and send out a link. If you're still on the modded 2.7.38, try the rooting method I mention for 2.7.35 and see if it works. I don't have the time lately to try but will do so as soon as I can to see if 2.7.38 is rootable. The previous .38 that was a firmware with third party advertisement wasn't rootable so I'm guessing the modded one will be the same.
[Android Head-Units] Cebulon48:
FYI, 2.7.38 runs well, without problems, no UI message. T7019a.

Different question: is there a way to delay start of an app.

Dashcommand tries to read from extSdCard before it is mounted, causing an error message?

So 2.7.38 is good? I'm scanning through the posts and it sounds like it has some sort of ads or branding?

Any noticeable improvements or features?

And how is rooting with this one?

Thanks!
[Android Head-Units] jpapadami:
Actually this was the firmware that I was looking for to repost. Thanks.

To by knowledge there are two 2.7.38s floating around. One is the one with third party advertising and the modded one that Skratchuk posted from #4895. I have tried the one with the advertisement and haven't noticed any differences from previous one besides the updated MCU and that it cannot be rooted. It can be rooted with the Baidu russian version, but you loose root once you reboot. I am guessing this would be the same for the modded 2.7.38 but cannot say as I have not tested it.

I also remember noticing a 2.7.39 version floating around the russian site that someone posted, but it never made it to ROM repository that is located at the header for each page in the forum. So I'm guessing that it isn't official for them or hasn't been tested.
[Android Head-Units] Scuddery:
Hey guys I've been trying to get USB to OBD2 hooked up and I thought I had everything needed, but after installing Torque Pro when I connect it to the port and the head-unit, I don't get a prompt or indication that the head-unit found anything new. I've tried restarting, trying without the hub I have, and the front USB, but same result.

As for it possibly being the USB OBD2 scanner: while it is a generic "Vgate" USB OBD2 scanner, it works well on a laptop and on other cars (also on other laptops). I've also been using a generic Bluetooth slim ELM327 paired to my phone for the last year on my car so I also know its not my car.

I was thinking maybe I finally need to update something, I've had this unit since December and I've never updated nor Rooted it before.
