[/QUOTE]Gibberish ? - You English is very good.

It is possible to break the thread up and put it into sub forums, but a) it would take someone weeks and weeks of work to do it - are you volunterring ?, b) pakidermo, the op, would have to give you his account details for you to access the thread and c) the XDA devs wont even give XDA an Android head units section, let alone a section for these specific units.

KGL make an Alfa 159/Brera/Spider specific model, there is an Alfa specific CAN Bus setting in factory settings, but I do not know how many of the OEM functions will work, whether you will get track and station displayed between your dials or the car menu on the head unit, it is possible, it works on some cars its just whether KGL have bothered to get it all working or not.

If you have B&M and you remove it then your mileage display will flash, so you will need to keep it connected and hide it somewhere. You cant use B&M as well as he Android headunit and why would you want to ? - B&M plays music from usb/sd cards and has a handsfree phone, so does the head unit, why would you want both ? ![/QUOTE]

Wow - quick reply, thanks :)

1: Sub forum(s) -- OK I see, "somebody" has been there - done that, with a no-go from the XDA devs! I wonder why?

2: KGL Unit -- Would/could you point me in the right direction , I just cant find it - and believe me I do know that Google is my friend.

3: B&M -- Ahhr, The Sales-rep has (again) been a bit "creative" in his description of the car. No B&M in that car.

Hi, I had a GS unit for Seat Exeo, and all It's ok also the external mic. I read the mod of external mic, but I don't like open the unit.

I connected a external mic from a Parrot, and don't run correctly, I think that this parrot mic is a electret mic, and the unit don't power this mic anyone knows if one electret mic runs with this unit.

I brought a CS-Y0003 mic, and I'm waiting to receive this, but I don't know if this mic will run OK with this unit. Anyone knows any mic that run Ok with the unit???

So what is your problem, the minor hiss ? Have you got an OEM antenna booster ie a wire at the base of your antenna ?

I think so.

Quad cores are out already.

You can split the RCAs to get 4 outputs, but you d loose fader controls, you d also have to split them again for the sub. You can also buy boxes that take the speaker outs and "un-amplify" them so you can feed them to your amp.
[MTCB Android Head Units Q&A] typos1:
Have you both tried EVERY CAN Bus setting in factory settings, including VW and Audi ones ? There is support for a lot of VW group cars (as you probably know the Exeo is just an old Audi A4).

No B&M ? Great, makes things easier.

Just google "android alfa 159".

Update on DSA’s pre-rooted rk3188 rom:

Thanks for cleaning out the apk’s that could be installed from Google Play if needed.

Used it for two weeks now, took two 6 hour trips using Google maps, Wi-Fi on my hotspot, and playing audio via Bluetooth during the entire trips. No issues.

Boot up time around 28 sec.

I’m Using Root Explorer, Xposed framework, App Settings, XposedMTC, Screen Filter, AFWall+, and Torque Pro with no issues.

Installed mcu 2.49.

[MENTION=254726]art103[/MENTION] This may be something to look at in your hotspot.

I found a work around for the Wi-Fi issues I was having, which trouble was connecting on demand to my LG G3’s hotspot. Setting the LG’s hotspot to a fixed channel fixed it; the LG was on auto channel which somehow confuses the Wi-Fi in the HU. I believe it is a bug in the HU since I haven’t had any trouble connecting to other devices with the auto channel on.

I am still working an issue with Google App (stops when using voice search). I tried all versions going back until one started working. The one that started working was back then called Google Search version; Google Search_3.6.16.1614640.arm.apk. Now voice search works without errors but I would prefer to use an updated Google App.

Two days ago my hu on boot up lost something and would only boot to recovery. I tried resets, restarts and only recovery. Picked # 4 on recovery to restore backup and it booted into DSA’s pre-rootedrk3188 ROM, re-installed all my programs and all is working well so far. Could someone explain how recovery from backup #4 works?

[MTCB Android Head Units Q&A] jkchr1s:
I didn't have that exact modem, but I added the one I bought to my AT&T family share plan for $15/mo. I tried the usb modem and had power issues, so I ended up buying an Android Go-Phone for $49 at Walmart and just leave it in my center console with tethering enabled. For some reason if you buy a wifi hotspot, AT&T will charge $20/mo instead of $15 (Which is why I opted to get a crappy go phone to save the $5/mo). I didn't want to fool with needing a powered USB hub to run the thing, and wifi is much more stable on my HU than the 3G was anyway.

Awesome find! Hopefully it's just plug it in, flash the rk3188 rom, and go! Surely they wouldn't change the pinout, it would make sense to use the same one so they could continue to use their stock of the same motherboards and sell these as "upgraded units".

Just out of curiosity, what brand is the unit you will be testing the rk3188 card in? I wonder if the original rk3066 cards are interchangeable between different builds. Hopefully they are all the same and this will work for everyone!

---------- Post added at 10:49 AM ---------- Previous post was at 10:46 AM ----------

Returning Head Unit, opinions on new head unit needed

Hi Everyone,

After weeks of issues with my Witson A6913, I'm returning it through a Paypal Claim and I'm going to order another head unit. I'm looking at a quad core for my 2006 BMW 325XI (E91) and was hoping I could get an opinion(s) on purchasing this model.

The unit I'm looking at:

QKGAC-7109HD

http://android-caraudio.com/en/andr...droid-444-quad-core-for-bmw-e90e91e92e93.html

Questions:

-Has anyone done business with this company?

-Would it be possible to flash android 5.0 with this chipset once it's available?

-Would it be compatible with current firmware on this forum so that I can root it?

-Is the cost reasonable?

Also:

I started a spreadsheet with sales teams and manufactures to be aware of so people don't have to go through the same hassles:

https://docs.google.com/spreadsheets/d/1-xTUqXqjLn8YjuICXn-OA-n02DuqxLrFhY2A_dUJsuw/edit?usp=sharing

*I sent a request to the creator of the thread here on xda to do so, but haven't heard back yet.
[MTCB Android Head Units Q&A] typos1:
This ahs been reported before, have you checked inside the unit that the antenna connection and/or the ground connection to the radio IC are connected ?

The latest update for the RK3066 apparently has sorted the Google app problem, so I guess its just a case of waiting for the RK3188 version - the software is the same, but different - everything you see is the same but there are other things (boot loader, recovery etc) that are different so theyre not interchangeable. Or maybe email KLD or Pumpkin and ask for the latest update ?

There are many GPS apps available in the Playstore that dont need any internet connection at all, have you considered using one of them if thats all you require the internet for ?

---------- Post added at 08:34 PM ---------- Previous post was at 08:28 PM ----------

The unit you returned will not be a Witson unit, they are just sellers, it is a KLD or a KGL.

The unit in the link you posted is a KGL, Android car-audio.com are just re-sellers.

The RK3188 is not compatible with Lollipop. The RK3288 is so there maybe an upgrade to this chip in the future just as there was from the RK3066 to the RK3188.

You can root it, a version of the RK3188 firmware has been rooted by DSA and only 1 or 2 pages ago the one user we on this thread of an RK3188 unit reported it works well. It IS NOT compatible with the RK3066/dual core firmware in this thread, see my comments above.

I think most people just buy direct from the factories on Aliepxress, cutting out the middle man, so no need for a list of re-sellers.
[MTCB Android Head Units Q&A] pbiggane:
typos1: Thank you for your reply, yes you had stated in a previous conversation with me that Witson is not the manufacturer, the MCU was MX. Thank you for the info on the Android 5.0 update, I may hold off until I can find the RK3288 chip. I haven't been able to find a quadcore chip for the BMW E91 on Alibaba or Aliexpress, so this reseller (android-caraudio) was the only way I could get the quadcore right now. I've seen quad core advertised on Alibaba and Aliexpress however after scrolling through their advertisement the chip is actually the RK3066, so they're falsely advertising the quad core.

I came to this thread through a YouTube video from the OP. I haven't had a chance to go through 1,000+ pages of replies here so let me just ask a few quick questions if I may.

I watch alot of YouTube videos on my phone, so this is something that I need to be able to do on these Chinese head units. However, alot of time I may be watching a video and then I'll pause it and come back a few hours later to watch the rest of it.

Now because these are head units and the fact that they power off after so many minutes of the car being off, will I be able to watch a video where I left off once the stereo turns back on? Or does it boot off and reboot completely? And if it does reboot completely is there anyway to bypass this?

Second, are there any currently available head units that are upgradedable to lollipop through rooting that are stable (preferably quad core)?

Thanks

These steering wheel controls are really kicking my ass. I got my PAC SWI-RC setup today and programmed, the LED on the PAC flashes when I press the controls on the SW, but the damn head unit will not registering anything. I've tried both the striped wire from the PAC to both key1 and key2 but no dice, as well as cutting the 3.5mm plug wired and trying the red wire per blackarrow's post. Nothing seems to work. I feel like these SW controls should not be this difficult and I'm missing something obvious.

RK3188 not support Firmware ?

Hey guys,

first Post so don't blame me pls. Finally i recieved my RK3188 Quad Core unit. The general Sound is horrible so i need the newest android version.

I followed the tutorial on the first page but it seems that i only can install the mcu image but not the Firmware. It allways says me:

=== UPDATE RKIMAGE ===

Find and check Firmware

E: Not support Firmware

Can not found firmware image ore invalid image

Update rkimage complete

Installation rkimage aborted.

Ive tried it on my Friends Radio ( he has dual core ) and it worked.

On my device its allways aborting the installation.

I've tried it with Coudu's 4.4.4 v4.2 KDL, KGL and JY versions, everytime the same result.

Any suggestions, how to get the newst Firmware ?

[MTCB Android Head Units Q&A] typos1:
The update to the RK3288 is pure speculation on my part - they have only just upgraded to the RK3188, it may be quite a while before they update to RK3288 if they do at all. It would make sense that they DO upgrade to it eventually, in the same way that it made sense to upgrade to the RK3188 - the only cost is replacing the SoM, they dont have to spend money developing everything else and they keep their product up to date (ish). Its highly likely, though not confirmed until DSA gets his RK3188 SoM, that you can simply upgrade the dual core units by swapping out the RK3066 SoM for an RK3188 one, in which case I would say get the quadcore and if they DO later make RK3288 versions available then you could upgrade your unit later.

They ARE NOT "falsely" advertising the RK3066 units as quadcore, they have just changed the title and not the body of the ad, this is them being a bit slack plus English is not their first language. Message them and specify that you want the quad core version not the dual core and if you dont find a listing of one for the E90 series, then message a seller and say that you want one with quadcore - these units are the same inside for all versions, its only the case and front that they change to fit different cars and they have so many versions available for so many different cars that they probably havent got round to listing quadcore versions of all the units they do separately yet.

They have been posted before, use thread search to find them, or download a KGL 4.2.2 image from the server and extract them.

No, possibly in the future, see above.

Use the reset hole, or I think you hold the power button on Astra/Cruze versions, someone a few months ago had a similar problem, cant remember exactly, use the thread search to try and find it, it was deffo this year.

FM will be gone in 2018/19

Hi Gents,

Our brilliant politicians is planning to shut the FM network down in 2018/19 here in Denmark where I live. This means the around 2 mill. cars will need either a replacement for their existing car-radio, or some sort off DAB add-on device!

No units with DAB.

I got a dual tuner DVB-T card for my unit and I listen to digital radio via that, so that is one option (assuming they broadcast radio on DVB-T in Denmark) or you could try the DAB devices by Dension, I posted links to them a few pages back or jsut go to Dension's site.

I checked the list and the MCU version v2.47 seems to be good. However, it remains the language problem, the right speaker when playing music USB / SD, and interference when playing music with USB / SD. These problems may depend on the type of MCU?

---------- Post added at 06:10 PM ---------- Previous post was at 06:05 PM ----------

There isn't "Cruze" in settings. "Mazda & Opel" doesn't work. The only setting that seems to work is "GM (Raise)" but there is still the problem of the language info display of the car and noise while playing music with USB / SD
[MTCB Android Head Units Q&A] typos1:
The setting for the CAN Bus is unlikely to affect the music playing, it may affect the sound quality as some cars send audio signals via the CAN Bus system, try all the settings and if none improve your low volume problem then try altering the volume levels in "audio".

I cannot think of why you are having the problems with music from SD card, I m sorry.

And as weve have discussed before I do not know about the language problem I guess the app has only been developed for Chinese and English, there are 2 options for you, either try and make an Italian version yourself or email the manufacturer and ask them to make an Italian version. I am assuming that you have tried re-connecting the original head unit, changing the language to Italian and then reconnecting the Android headunit again as I suggested before ?
