Hi,

Could you please describe the BT connection issues. I can't connect to any bt device. The bt keeps telling it is initialising??
[Android Head-Units] nomorebigideas:
[MENTION=9653906]cennaciri[/MENTION] - the way I've found to solve this is to use Tasker to launch the OEM/Stock Launcher, then close it, allowing you to effectively boot into your chosen Launcher (I use Nova).

Here's how w/ Tasker:

Profile:

Device Boot

Tasks:

1) Wait (500ms)

2) Launch App 'Launcher' (or whatever com.X.X the package is displayed as)

3) Wait (500ms)

4) Launch App 'YOUR CHOSEN LAUNCHER HERE';

5) Wait (500ms)

6) Kill App 'Launcher' (or whatever com.X.X the package is displayed as)

Upon boot, Tasker will run this script, open (and close) the OEM/Stock Launcher and open your chosen Launcher. For some reason, this is the only way I've found to initialise Bluetooth correctly. Be sure to clear cache/data of the Bluetooth App as well just for good measure.

I run a OnePlus 6 (9.0.3) and automate WIFI Tethering from it.

HOWEVER - since updating from 9.0.2 to 9.0.3, the BT on my Android HU 7.1.1 won't stream Media Audio. Calls/information is all fine. and BT Media Audio streams track/title info, allows basic controls and goes through the motions, but there's just no sound. It's infuriating. Anyone else experienced this?

Hey - some people say you need to remove the OTG resistor on the MB to get it recognised via USB. I haven't, so can't help - just reporting what I've heard.
[Android Head-Units] thetodor:
Yup, I've read that as well, and went as far as to look up the PX6 specs. The reports of people doing that were for the PX3 board, but there are equivalent pins on the PX6. I haven't opened mine up yet (for warranty reasons), but if I can't restore via an SD card or USB flash drive, I guess that will be the next thing I try. I'm still waiting on a stock image from 4x4shop (it's been 2 weeks).
[Android Head-Units] tricky_o:
I was also stuck on the android logo once after I tried a USB OTG camera which seemed to break everything and lock the device. Talked to Louie and I reset it using the button next to the TF card slot on the back of the device and a _reset name firmware.

[Android Head-Units] keliuss:
Hi folks, I recently installed a 7.1 px3 head unit in my E60. It is a generic Chinese unit off ebay. There is no radio in the menus. Obviously I can use my stock radio in the background but I'm surprised at lack of radio as it can be seen in screenshots of the many different sellers. Does anyone know if this was included in earlier software versions? Do these units have the hardware for radio? Is it possible to downgrade to earlier version etc?

Many thanks

Keliuss
[Android Head-Units] Rb94301:
Never seen it since sep 2017 models came out with radio unless new ones come with attachments like avin models.

Has anyone extracted the APK that contains EventService? I just ordered the Avin PX6 for my E60 M5 and am planning on writing a new launcher as well. I'd like to get started on the software before my order arrives.
[Android Head-Units] garrypeterson:
Please disregard, I was able to get a hold of it.
[Android Head-Units] bradsinram:
is it 8.8 inch? mine was to the right of the touch screen. very easy to miss. you slide your finger from the center of the display all the way to the right edge of the touch screen and right there will be a sd slot. the card will actually touch the screen when you slide it in. i can take pics in the morning if you cant find it.
[Android Head-Units] nomorebigideas:
Doers anyone know how to get the generic (or AVIN) Android HU's to load up on the Android side? Mine keeps loading on the OEM side?
[Android Head-Units] Werra2006:
When you turn off the car do so while in android side NOT OEM
[Android Head-Units] koutsouk:
Does any one have a clue why some navigation apps do not output sound from left front speaker when you are in idrive audio source but on android screen for navigation?

Example Sygic Navi voice is heard but Sygic Truck and igo does not at all unless you choose aux as a source.

Here WEGO maps sound is coming but is crackling.
[Android Head-Units] swa0000:
a) The events depences on your car & Android model .

b) the Eventservice contains up to 36 different car models

c) i only extracted them for my launcher (F11/NBT)

So you have to wait until you can start debugging
[Android Head-Units] nomorebigideas:
For the sake of clarity, can anyone share the "factory.xml" for a CIC, 6.5" (OEM) HU? Mine is a generic Aliexpress unit - currently using the 'YouChang' factory client xml but it consistently loads on the OEM side and not the Android side.
[Android Head-Units] koutsouk:
if the unit does not boot with an sd card inserted :

Download in your PC Mini Tool partition Wizard

Mount your sd card

delete all partitions and make the card virgin again.

Rebuild MRB

Make New partition in non allocated space formatted in FAT 32 file system and you are good to go.

Remove sd card and place it in your head unit.

It must work.

It worked in my head unit and now i have all my music stored in the sd card.

How that helps.

[Android Head-Units] nomorebigideas:
I was forced to format mine with OEM FW, then upgrade to the latest available FW, and whatever I do it always starts on the OEM side. Is there a setting in Factory Settings? Or a line in the 'factory.xml' file that can be manipulated? Presumably we're all using the same/similar FW/Factory/CarType files?
[Android Head-Units] kroberts057:
Quick one - I've got an E60 M5 as well & have the 7.1 unit from Avin. The M button has been mapped to take the unit out the the "original" iDrive menu (irritates the hell out of me). Does you unit also do this?
[Android Head-Units] thetodor:
Mine doesn't do that (E63 M6 here). I would hate to lose the M button!

If you go into the unit's factory configuration (PIN is 1314, I think), there's a section there about button mappings. See if you can change that one.
[Android Head-Units] kroberts057:
Yeah, it's really ruining the driving experience.

I've tried the "learning touch keys" function but can't get it to do anything / figure it how it works.

Where did you get your head unit from?

Might try buying from the same place & sell the Avin.

Thanks for trying to help
[Android Head-Units] thetodor:
I think they're all the same, just possibly different configuration. I bought mine from 4x4shop.ca, but that was really a mistake. I could have gotten the same thing at almost half price from aliexpress (and that's what I recommend that people do). I haven't played with those configurable buttons either, I just noticed that that functionality exists. Maybe contact Avin and ask them - that's the only useful thing about buying from a North-America-based distributor... although people in this thread have actually had better experiences with customer support from China-based "Ugode".

By the way, both Avin and 4x4shop claim they have the units "in stock" in California or Canada, but they both ship directly from China via DHL, and they both declare a fake lower customs value, so that the package is below the threshold where you have to pay customs duty fees (I know this because I've ordered from both). Most sellers on alibaba/aliexpress do the same.

Hello my friend .

I also have ISTA+ errors (B7F8C3 Connection, headunit to CID: No communication) with my 4.4.4 unit in my BMW F48.

Did you find a solution for this ?

[Android Head-Units] garrypeterson:
Is yours from Avin? I haven't found "learning touch keys" on mine (E60 CCC Px6).
[Android Head-Units] kroberts057:
Yeah. They recently sent out a firmware update that added it. Mine is a 7.1 PX3 for CCC. Shoot them an email to see if there is an update for yours.

The feature doesn't work with all my efforts so don't think you're missing out on anything.

Front camera

Yesterday I installed front RCA camera, but there is any other way to get it to show image just when I got to "DVR" app from the main screen, and it doesn't record anything, I only have a button to go back.

Maybe I can install DVR app from the store but then I need to start it manually every time I go into the car.

So it can not record anything, it can't be used as a front parking camera.:(

Did I wasted 20$ and 5h of installing or you guys have something solution or idea?:confused:

AVIN 4.4.4 MCU Update and latest firmware

Hi Guys,

I'm hoping you can help me. I recently bought a 2006 BMW 335i M Sport E90 and the previous owner installed an AVIN 8.8 Android 4.4.4. model. The previous owner said the unit worked fine until he did an MCU update but mistakenly updated from a CCC to a CIC image file. Ever since then, he has not been able to get it to work with the idrive system. I contacted AVIN, but because it was purchased by someone else, they are refusing to help me. Here is what currently works:

- Unit displays no signal on ignition start

- Once you click on the unit it works as normal and I can see all of the screens for the android UI

What does not work

- BMW idrive does not work at all

- Cannot play any music from BMW stock radio

- No music or sound comes from the android unit.

- no music or sound comes from my iphone thru carplay via the carplay adapter

I think my main problem is not having the CCC MCU update config. Does anyone have the latest CCC MCU update and latest firmware update for my device?

Also, I read about the SD card tool to reinstall firmware, but does that also reset the MCU to the correct version of the device?

Thank you so much for any help you can provide.

Android Headunit 8.1

Hi guys I have Headunit 8.1 but I have a couple of questions

1 when I make or receive calls the volume is really low just wondered if there’s a fix.

2 I have a none idrive setup but I purchased an idrive controller which controls the headunit. I was wondering if it’s possible to remap buttons.

TIA for your help Dave
[Android Head-Units] Werra2006:

[Android Head-Units] dibsta:
Hi thanks for reply I’ve done this but still low maybe iphone issue
[Android Head-Units] jjames91!:
After paying AVIN for support and finally receiving all of the updates, I am still having an issue that hopefully, someone can assist on:

--When I start the car the display shows "no signal"

--After 2 minutes I can click on the screen and see the Android UI

--I can do everything within the Android UI

The Issue:

--I can not get any sound out of the unit

--The I-Drive does not work

--The BMW stereo does not work

--When I click on "Car Info" within the Android UI I get "no signal"

Troubleshooting steps:

--Under factory settings 1314

--I switch the car to Alpine (also to Harmon Kardon)

--I switch between i-drive A and i drive B

--Save configuration to factory.xml file

--Still does not work

--I tried the reset sequence with the bmw radio "mute/eject/eject - No change.

I know the unit worked because when I test drove the car all of the functions, I-drive, BMW stock radio, sound from my iphone via apple car app worked flawlessly.

I think the problem is that the previous owner updated the MCU with the wrong firmware. The firmware you provided said CCC in the script, while the previous one did not. Could this be the issue? Is there a way to fix it?

If you can think of any troubleshooting steps, please HELP!:(
[Android Head-Units] kalinkamaen:
What uint do you have? CCC or CIC or NBT? Have you tried to upgrade MCU files on your unit?
[Android Head-Units] jjames91!:
Hi, I have a CCC unit.

Yes, AVIN sent me the CCC MCU file and it successfully installed.

I guess my question is this, if you install a wrong MCU version on the android unit can you just reinstall the correct one like I did or is the MCU screwed now? The device seems to function fine, except:

- i Drive does not work

- No sound coming from the device

- Cannot access stock BMW radio or thru "car info" on the android unit.

Thanks all for the guidance.
[Android Head-Units] rod catterall:
Is your ccc idrive working? That would explain no sound and not able to get to the ccc menu at all.
[Android Head-Units] koutsouk:
Can you share the CCC MCU file please ?

Which version is this MCU file ? You can see that in factory settings please.

You have the 7.1 Android , correct ?

Sometimes CCC unit can go bad from wrong MCU file installation. I had this issue with a previous unit that messed up my original CCC unit and I had no other option that buy a new one.

I think that the only way to check is to put the original system in and see if it is working.
[Android Head-Units] kalinkamaen:
Sounds like you MCU are broken, but i do not know the answear of your question if its fixable. Android side has nothing to do with MCU per my understanding.

Hi All,

I never thought I would have to use XDA to fix my car ;) I have several problems I posted on Bimmerpost but it looks like not many people are looking there. Hope there will be someone here that can help me. First of all I am not sure about the brand of my unit however I am thinking it might be very similar to avin. I will attach the screen shots so hope you can tell me what it is. I have two main problem and a question the first problem is my front bumper looks red I think it is the hood sensor and I believe my car does not have one.

is there a way to disable this?

The second problem is about the rear view camera the parking sensors work fine guide lines work fine but the radar is always red as if I am too close to something.

is there a way to fix this.

Finally the questions I have been told that this unit can not be upgraded to a never android version, which sounded strange, is there a way that I can upgrade the android. Not knowing the brand will it be possible or too risky to even try. Here are few photos that I hope can help some one identify the brand of my unit.

Thanks in advance. Regards,

Anyone know how to change the ringtone on these units? Or at least where they're located in the file structure? Also, mine keeps loading "Music" APK from login. Anyway to stop this? Tasker can't seem to Kill App (non rooted - 7.1 version).
[Android Head-Units] gt2009:
Regarding the Music app, you will have to disable it with something like Titanium backup -- requires root as its a system level app.

has anyone installed noozxoide eizo-rewire pro on px3 android 7?
[Android Head-Units] nomorebigideas:
Seems like this is just a stereo width algorithm - I've known similar in professional recording. Pushing the perceived width of the stereo mix (and remember it's the whole mix and not just individual stems) comes at the detriment central mix (usually reserved for bass, kick drum, low-end instruments) so you'll lose bass clarity. There's no right or wrong way in sound, but usually anything like this programme is a gimmick and will simply destroy the mix of the engineers / producers.

@ everyone - can anyone shed light on why my 7.1 unit INSISTS on opening on the BMW side? I have to re-format and reinstall everything to get it to open on the Android side, and even then it doesn't last! (Yes I've closed it down on both the BMW and Android sides). Is this a Factory.xml setting? Or something that can be triggered in settings?

Hello,

I have already opened a new thread for this issue but maybe it is more relevant here. These units are available for E83, E84, F25, F30 and other BMW models, share the same hardware and only base, connectors, harnesses and MCU versions change according to specific model. They are probably produced from one factory but u will them around with brands like: MEKEDE, NAVIFFLY, DASAITA, UGODE, AVIN etc. So there are CCC, CIC, and NBT MCU versions. Mine is for E83 X3 and came with a CIC version. Aliexpress sellers support is zero... Anyway I need desperately to update MCU and I cannot through normal menu way. It just recognises the update file, suppose to start procedure and then u wait forever and nothing happens. It is a common issue lately since it is being discussed many times at f30bimmerpost forum. Can some expert guy pls suggest a different procedure like renaming the file and force update it somehow during booting maybe??

the file is in an mcuupdate.bin form.

Thanks a lot!

Issues Upgrading Firmware

Hello Everyone, looking for some advice here with my Android unit. Specifically an 8.8” E60 CIC. I’m not sure of the exact brand, I assume it is Chinese made. I bought it second hand on eBay for a good deal and didn’t want to pass it up. However I am having an issue installing new firmware.... I have looked through some of the posts here and tried them but once it reboots, the device acts as if it’s going to install but then says error. It then reboots as normal a minute or so after the attempt. Do any of you guys have any suggestions?

I have successfully installed firmware in the past without issue. And I have not upgraded the MCU since I have received it.

Wondering if it's possible to rewire a new microphone in in place of the one they've used? That way I could hardware it to above my head, presumably for clearer audio (but this wouldn't address the BT interference).
