Tired of the Head Unit

Hi! Do you know anything to start FastBoot in the Unit. I tried all your help 2 weeks ago but I screwed up the board with the soldering iron and one friend of mine attached the resistor to the board and added a button to activate the resistor. Now I can start the unit in recovery mode but I'm unable to mount the SD card: I tried xFAT, FAT 32 and NTFS and nothing Happens. I tried wiping the cache and the factory reset and nothing happens.

I installed the Rockchip drivers in my Windows 10 PC but I cannot see the device. And when I try to start the Recovery Mode with the PC connected to the device the "No Signal" screen doesn't dissapear. If I disconnect the PC and I try to start Recovery Mode it starts without problems but I cannot find the device with ADB.

Any idea or help?
[Android Head-Units] smahel:
with the resistor connected will certainly not work ADB via USB, try to disconnect the resistors in both positions. If the PC fails to connect, try this: connect an OTA resistor, upload px6_format.zip to FAT32 formatted USB stick, insert into USB port, remove SD and connect 12V and wait - even a few minutes.

I saw a comment from BMW guy stating to make sure in the settings AUX is set to automatic for switching.

---------- Post added at 11:57 PM ---------- Previous post was at 11:48 PM ----------

Is the AUX automatic switching enabled?

Are you certain the cables into the hu are fully in, did they click? Finally if you put a headset in the aux on the harness can you hear sound.
[Android Head-Units] smahel:
If you manage the ADB approach, you can also use the procedure that worked for me:

This needs to be higher. Amazing find.

Navifly Unit, PX6 Running 8.1 in a 2009 E90.

Installed px6_20190125.zip and I now have full i-Drive knob functionality in Carplay (Autokit - Wireless).....this is a gamechanger. Never had this working it before.

NB: Steering wheel controls still not working (mapped incorrectly, can't remap).

Hi guys,

I got sent what I thought was a MCU update file for bmw CCC but turned out to be CIC.

My unit which is a 7.1 now only shows 'no signal' and when i turn off the car the unit is still powered on showing 'no signal'

I have removed the resister and bridged the other two pins and have flashed a new px3 file using rockchip batch tool but the unit is still showing 'no signal', tried this serval times and still no luck.

Any suggestions?
[Android Head-Units] acquescy:
Thanks again for your help. I will try with your steps. The manufacturer is not answering my questions that's why I decided to break the warranty label too. I have a switch that when I press the resistor is connected to the OTG and when I release is like I don't have any resistor.

Did you have Windows 10 in your PC? I'm started to think that Windows 10 could be a problem. And, when you wrote that you connected a 12V battery to the unit, did you mean that you connected it to the car battery power cable or did you create a new cable and connected it a to 12V battery?

When you brik the unit, did it started and stopped on the android screen logo every time?
[Android Head-Units] smahel:
Windows 10 64 bit

don't press switch for ADB access

I connected a motorcycle 12V battery - see picture

Yes
[Android Head-Units] theadonnan:
Thanks. I tried a nano to micro SIM adapter, but it didn't seem to see the card despite being plugged in gold side down. T-Mobile tablet sim card attempted.
[Android Head-Units] acquescy:
Thanks again! This method finally worked. After a minute with the USB connected the update started and I have the Unit back. Now I rooted it properly and I'm trying to update to Android 9. This is the step I was doing a month ago.

Do you have the Android 9.0 update for this Unit? I had it but I'm unable to find it again.
[Android Head-Units] smahel:
:good:

I have an Android9 update (px6.zip). However, it does not contain a recovery image and without it it is not possible to upgrade to Android 9. You'd have to have a complete Android9 image ... Unfortunately, I didn't find it anywhere.
[Android Head-Units] acquescy:
Thanks again! That's why when I attached the USB with the Android 9 PX6 zip file nothing happens on the unit. This should be because my unit and maybe yours is not MTCD or MTCE, I guess. While taking a look to the settings in the unit I don't see the MTCD in the MCU ver name like I read in other threads.

Screenshot of my unit settings attached.
[Android Head-Units] smahel:
Of course not, BMW head units are not MTCD, they don't have any buttons, just one reset hole ... And lousy dealer support.

Factory.xml location ?

Hello,

I'm planning to update my PX6 unit ROM. Before that I'd like to make a backup of my CarType.xml and Factory.xml in case of any problem during the update.

I've found the CarType.xml file in the oem/app folder but I can't find the Factory.xml file.

Can you please help me find this file?

My Head Unit infos are :

MCUVer: 023042bGS-NBT-HW7-190118

FrameworkVer: 8.1.0 OPM5.171019.019 eng.zxw.20181228.162012

APPVer: 2019040301_1280x480_970

Thanks in advance !
[Android Head-Units] smahel:
This backup makes no sense, CarType.xml in the oem / app directory is truncated considerably and cannot be updated. The files from the seller are used to update. Here you have them, they must be in the OEM directory on USB: https://mega.nz/#F!wRE0UAQZ!SnL8bA8yStSyTCdBPkN-Jw
[Android Head-Units] RaceX58:
Thanks a lot for your reply !

I have a last question. If the update goes well my current cartype.xml and factory.xml files won't be deleted? Am I right?

For information my unit comes from Navifly and not AVIN, but should be the same if I'm correct.

Thanks again !
[Android Head-Units] smahel:
Yes. But CarType.xml is up-to-date and if you leave the <client> ALL </client> line in Factory.xml, you get the maximum setting possibilities in HUs Factory settings.

The only thing you cannot change other than uploading Factory.xml is just <client> ALL </client> and <password> 1314 </password> , others can be changed in HU. Factory.xml can of course be edited too.
[Android Head-Units] RaceX58:
It starts to be more clear thanks to your answers !

But where can i find my Factory.xml on the android's directories structure? I haven't found it in the oem/app
[Android Head-Units] smahel:
You will not find it in HU, Factory.xml is not stored in any directory. It is used only for initial setting of the unit. You'll only find it at vendor or on the Internet.....:laugh:
[Android Head-Units] RaceX58:
Okay !! I finally got it :good:

I'm good for some update now !

Thanks to you

Did you buy the GPS splitter that AVIN offers? It allows usage of the factory GPS to be used with the factory stereo and the AVIN unit vs using the aftermarket GPS antenna provided.
[Android Head-Units] m5james:
Three requests for those who know how:

- Make the stereo be able to see my JB4

- Brightness slider on the pulldown notifications bar

- Multiwindow so I can do Showbox/Youtube/Pandora, etc and Waze together

If you flash one of the older firmware versions are you able to root? And if yes does anyone have a root able version that they could pm me. I want to install the viper audio because the sound quality on this leaves something to be desired
[Android Head-Units] mantrajt:
Good to find this thread. I got my Avin few months ago and I'm little bit disappointed. It's laggy, not fully integrated with iDrive , can't remove "cards" of stuff I don't have like in the launcher, gps had random behavior and Android auto is advertised to work on Avin's web page... But it doesn't. I wrote to get instructions on how to make it work and got no answers. Also in that mail I asked if any updates to Android version is near or if this is it.... No answer. Android auto runs on 5.0 or higher.... It is a great miss not to have this feature.

Any idea if there are custom ROMs with higher Android versions?
[Android Head-Units] aclearersky:
Ok so just to verify king root works on the most recent update. I installed viper4android but it seems that the included equalizer is overriding the installed one. I made sure to change it sound setting but it still doesn't work

When using the launcher, since it's designed for other head units, I was only able to get it to work in tablet mode.
[Android Head-Units] m5james:
I think he's referring to when it asks iffor were MCB or MCD, or whatever it was. I tried that launcher as well, but it's almost got too many options lol...I'll have to play with it more. I noticed it added a TON of apps to my device, most of which don't work...seat controls, two FM radios, TV tuner, something with three dots, a reboot, etc all of which do nothing.
[Android Head-Units] mantrajt:
That's exactly what I meant...MCB or MCD. It seems to be a good launcher. But I don't want to set it up wrong.
[Android Head-Units] aclearersky:
Any idea why viper4android does nothing?
[Android Head-Units] CleanKM:
The unit is neither MCB or MCD. From what i remember there was an option to use the launcher as just a tablet mode. You are correct, the launcher itself adds alot of options that don't function/not designed for this unit and requires some work to clean it all up.

I am thinking of getting this display. My biggest concern is that the sound will be crap what might be no problem if I use android auto with the phone connected to the bmw bluetooth.

So can you tell me how good android auto works for this unit?

Do I need the avin adapter?

Can it autostart when I connect the phone (maybe by tasker)?

Did anyone tried this app:

And one other question. I read that android takes about 10-20 seconds to boot. Is the idrive accessible during boot or do I have to wait up to 20 seconds to see my parking sensors?
[Android Head-Units] daxtor:
iDrive is usable at the time you turn on the car, just as usual. You don't have to wait for the Android side to finish booting first.

I used the headunit reloaded app. However the image will be stretched horizontally. You need to get in touch with the app owner so he can give you a custom build version with the correct aspect ratio support.

Hi every one

my head unit is almost identical to that of AVINUSA. My problem is that the external SD is not recognized by applications like Sygic or Here as external storage and will only install maps on internal. The path of my SD is mnt/external_SD1. Is there any way to make it recognized as external storage.

Update is not a valid package

Hey guys,

So I tried to update my unit with no success...

I used the file px6_20190611.zip from this link :

https://mega.nz/#F!IJEUFIwQ!q0XIcT4x7RFE1hcFU4pfIA

I've renamed it px6.zip and uploaded it on an formatted 16Gb USB drive (FAT32, MBR).

The unit detects the update but when I click install I have a message 'This update is not a valid package' or something like that.

I also tried from a 16Gb microSD card with no success too.

I've opened the px6_20190611.zip file on found the following :

--px6_20190611.zip

----px6_20190611\

--------app\

--------px6.zip

Shouldn't I use the px6.zip inside the px6_20190611.zip ? But why is there an app folder with all the apk ?

Thanks guys for your help

Hey guys,

Since I updated my unit (MCU and ROM) i have a problem with my steering wheel commands.

Before the update I was able to use track+ and track- to play next/previous songs. Like all of us I had to start a vendor app before (music player, video player, bluetooth, etc...)

But since the update the track+ and track- only pause the playing song...

I tried every rom I found with the same result.

My original rom was : 8.1.0 OPM5.171019.019 eng.zxw.20181228.162012

Does someone here have this ROM version to share ? The oldest I found is 20190125.

[Android Head-Units] CharismaKenzie:
That doesn’t seem to work with mine, but I’m wondering if perhaps my CANBUS plugs aren’t connected properly. For example I have Automatic Aux selected in the system properties but the Business CD always starts on FM Radio. Do you have an E83 setup also?
[Android Head-Units] CharismaKenzie:
I did a little reasearch in the CANBUS on AVIN's support page. I think I have them plugged in right; I'm guessing the E83 just doesn't support those features. I've noticed another wrinkle/clue - if I boot in "Original Time" then switch to GPS time, the time shows correct. Weird that it won't show correct if I boot in GPS time, but does if I switch. This is driving me slightly insane.
[Android Head-Units] Chrisu02:
automatic AUX only does work if you have an BMW navigation system installed, not with normal radio as its changing the Aux via virtual Idrive controller selection.

The Unit does not have an internal battery to store the time when the car is shutdown thats why it does loose the time.

the shipped with GPS mouse is very slow in booting, people who have a stock navigation systems mostly use the internal GPS with a splitter, this way the GPS signal is already 3D fixed when the unit is booted.

without a factory antenna, i think the easiest way is to get a permanent internet connection to the car navigation or root it like in the other thread explaind and boot a gps app with tasker.

Chri
[Android Head-Units] CharismaKenzie:
I am considering getting a permanent internet connection as my Cellphone contract is currently up for renegotiation. Do you know if a USB cell receiver can connect directly to the unit, or would it have to be something standalone that can broadcast wifi (like a cellphone wifi hotspot)? I might try rooting it.
[Android Head-Units] keliuss:
Mine starts up immediately on FM, but once the Android unit boots fully and starts up the music player, it takes a few more seconds to switch over to Aux. This delay caused me to think the unit was not auto-switching. I have one of my Business headunit buttons mapped to "Aux" and for the 1st few days after installing I was pressing the button to switch it over myself manually. After a week I noticed it switches itself.

Keliuss
[Android Head-Units] CharismaKenzie:
.

Youhave an E83 as well? I wish there was a way to program the Business CD to default to Aux on startup.
[Android Head-Units] keliuss:
No, I have an E60 with CCC. Before I got this unit I had a cheap bluetooth transmitter on Aux but the radio would never start on Aux. The Android unit seems to have solved this problem as it now auto-switches to Aux.

Keliuss
[Android Head-Units] CharismaKenzie:
Hmmm... it doesn't seem to work with the E83. I've messaged AVIN to see if it's supposed to. Interestingly, I noticed that if you shut the radio off in Aux mode prior to turning the car off, it will stay in Aux when you turn it back on. I wonder if there would be to wire a relay to the power button on the Business CD unit to mimic this.
[Android Head-Units] Chrisu02:
I saw some kind of USB stick, but you never know which LTE Bands are supported.

I have installed a standalone device to my car, to be more independent and have full controll of everything.

I have connected it to KL30g, so it does boot as soon as i unlock the car and run`s 30 min after i locked the car.

You may take a look at products like, Mikrotik WaP LTE, the new Mikrotik WaP AC LTE or the Teltonika RUT850. (EU LTE Bands)

The Teltonika is easier to install and mostly cheaper, however i have installed the Mikrotik WaP LTE with external antennas to my car, as it has more possibilities to configure (more complex) and does boot faster.

Hi all,

i have a problem with e60 ccc (px3 android) "No Signal" error on OEM side only. Android side works great + i-drive wheel, steering wheel buttons - all working great on Android

Would Car Type settings have something to do with this? I mean if i try to update Car Type Configuration? Is this safe to do? If yes, where can i find and how to update it?

Currently i have everything listed in Chinese in Car Type menu, but using Google Translate i am certain i chose the right option (e60 small screen), but i still get No Signal.

MCU and ROM updated to latest versions, no luck with this No Signal issue.

Thanks in advance
[Android Head-Units] nowaq111:
Ok, let me try to ask specific questions:

I found Facotry.xml and CarType.xml from that google drive (Ugode 10.25) link that keeps appearing in the thread, however when i opened it to read the lines i noticed it is different than the one i have.

Most obvious thing is the factory menu password. Mine is 1314 and in that XML versions it shows <password>2018</password>

Can i update my factory.xml with this one or it is not safe?

Can this mess up everything because of the different password (as i understood password line cannot be edited manually and saved in .xml) ?

Can i somehow backup my existing xml?

Or if anyone has factory.xml and CarType.xml with password 1314 can you please share it.

Thanks in advance
[Android Head-Units] smahel:
Here you have Factory.img and CarType.img translated. Use is safe. In the Factory.img file, the most important is the line <client> ALL </client>. In the Factory.xml file you can try out all the clients I found. There are more vendors, but many use the same factory settings:

high-grade,GS,GeShi,ALS,HLA,XHD,Hezheng,CHWY,XinCheng + ALL and common. When using ALL, you will get the maximum setting options in your version of Android firmware. You can set your own 4-6 digit password in the <password> 1314 </password> line.
