It would all be so much better if we could get the source code for the mcu and the unit...
Maybe we could do a "group buy" for the sources
Being a chinese product its just a matter of "asking" to the right person.

__fred__ reverse engineered the MCU some time ago with IDA Pro you may check here.

but it still require special programming skills to get use of them.

Its a nightmare to code anything with reversed code.
Original source would be much better.

I ordered an Android Head Unit from ExclusiveCarAuto.com. It has Android 9.0 and PX6. Maybe it will be arrive tommorow. I am looking forward to the system...

But I already have questions atm:
1. I saw that there is an update available for Snapdragon units and the user can change the default music app. Is there a way to change the Music player in PX6 systems, too?

2. Where I can find generally the newest updates for my head unit? There is a folder at mega.nz with PX6-updates but which one is the newest? PX6-9.0.zip or PX6-9.0_20190929?


Best regards
Pascal

1. afaik not.

2. https://www.amazon.de/clouddrive/sha...gzVOHPXQMij3zv

20190929T is the latest that i got, ask your seller for an update, if you get a newer file, please share.

the reason is for using BT is for example:
* BMW Performance Analyser (require also G-sensor ect.)
* external BT Keyboard.
* External BT Touchpad (for shortcuts, for example Tsumbai Ai01 )
* BT ODB dongle for diagnosis
* BT Microphone for common use like google Assist

All units should come with the latest software installed, PX6 next update will be later November Avinusa said

I've research a bit and found that there is two versions of PDC. One has its own speakers (under foot well and above rear right wheel behind the seat belt). The other in fact communicates over CAN and sound is transferred via HU to the ordinary speakers, this is what my E87 has. That might be the reason why nothing happens when engaging reverse gear (no change on display), also nothing when pressing the PDC button (no light); the Chinese engineers may have overlooked this.

If only I could find some way to make it beep at least ... Disconnecting CAN from Android is the only way to make it work, it seems. But which functionality is lost? Dashboard, iDrive button and steering wheel buttons?

And Android needs to be powered by other means then. I'm thinking of getting power from Quadlock pin 13, which is often used as remote turn on signal for external amplifiers. An added benefit would be that the screen will turn on immediately when the car is unlocked, and will remain on for a while when locked.

[marakeh]

so move pin 15 to pin 13.

do you know which fuse is pin 13 connected to and how long is the connecting fuse powered after power down?

Does anyone know if the new 'Android Auto for phone screens' app works without physically connecting the phone via USB?

What I know is if the vehicle has WiFi functionality then will work without usb cable

[floc]

currently, androidauto (AA) works via wireless only with a limited number of galaxy/pixel phones AND (obviously) only with a wireless androidauto server headunit on the car (some car of vag group, some kenwood headunits),

On android headunit we can use "headunit reloaded", an app that use the original aa app in server mode and make it available via wireless form the phone (a wider range, but compatibility is not guaranteed, you have to try).

with this kind of logcat detection I think we could detect the idrive input from every apps. I'll try as soon as possible

did some test. Unfortunately it does not seems to pick up all the entry we got on manual logcat, I'll try to figure it out with the tasker dev

Did you do this? I think the BMW mic needs more voltage than the Android unit supplies, maybe 12v. Could anyone measure this? We need to know the voltage BMW supplies to the mic, the voltage Android supplies through the mic in cable, and the voltage to the internal Android mic.

The OEM mic is active and has noise cancelling, much better than others. We can probably make it work by supplying the correct voltage.

Is this BMW mic?

[Firefly1337]

Attached you'll find my app that makes the iDrive controller usable in any app.
Bear in mind, this one only works for Snapdragon devices and requires root and Xposed.
Source is attached as well.
Remove the '.pdf' ending from the apk to make it work.
As always, use at your own risk.

I removed my unit from my car today and will return it on Monday.
Good luck

No, but it stays powered as long as the HU is powered. I have fitted an external amp which use pin 13 from QL for turn on signal, and it is always powered and ready as soon as the car is unlocked.

Do you have an original camera? Maybe it detects that I don't have one and defaults to its own (ugly) screen.

If you press and hold the Menu button to activate the BMW interface, do you see a working OEM interface there? If so, maybe you could use Tasker to switch to BMW side when reversing.

No, I did not... I was too busy with other things and work. Anyway, I'm not an audio expert but I always thought that mics do not take any voltage, they have two signal wires and sometimes shield wire. This is a simple induction principle and amplification is handled by, well amplifier... unless there is something else going on with these OEM mics (like active electronics) I don't see any issue here. Once I have few minutes spare I will check my theory.

Edit:
Besides, even if the OEM mic does require power, we don't have to worry about that as all we do here is tapping into the signal wires + and - and passing that over to Android unit. The original mic wiring is intact if you know what I mean.

Yes, it will get power from the original connection. Provided that BMW always powers the mic. Let us now when you find out. The Android built in mic is still not good enough, so I think a lot of people will search for a solution, and this can be it.

I'm in a bit different situation, because I will retrofit a BMW mic only to the Android unit. I tried it on my PC, which supplies 3.7 volts, and it is barely audible. This is an active microphone with internal electronics which needs power.

In this case I will have to investigate a bit more. When I was checking wiring diagrams for E63 all mic connections were shown as + and - which, in my understanding is signal. Usually there is GND indication on a wiring diagram and some sort of voltage reference if part is to be powered up. But again, I'm not electronics specialist either and I might have misread something.

As I said before I'm not even sure if this would apply to anything newer than E60/E63/E90 CCC variants. I didn't check wiring diagrams for F cars and this could be completely different.

I might be able to check voltage readings on OEM mic later on today. Will keep you updated.

Just out of curiosity, what part number is your mic?

Hi Hi

Does the most recent update for the SnapDragon Android 9.0 solves the GPS audio switching issue?

This is getting a lot irritating as i do not have the sound coming to the lft speakers, instead to the small speaker provided by the manufacturer which i did not connect to.

I dont have a camera. I'm thinking of getting one but I also don't like MCU PDC graphics and prefer original PDC even without camera.

How to install Xposed for Snapdragon device? Ist there custom recovery like TWRP? I want to make a backup before I start messing up with the system

EDIT: I followed this instructions to get Xposed
https://f30.bimmerpost.com/forums/sh...&postcount=409

Great job with the app!
However I must say that for my use case, there are not many benefits. I use it only for Waze and Deezer. It doesn't work in Waze, it works in Deezer but its clumsy. Which is not strange since those apps are designed for touch inputs.

[Frankly30]

I was wondering if we need root access to listen to the iDrive controller inputs.. I was thinking of configuring a wrapper for navigation apps, that simulates touch inputs for zooming and moving. I wonder if thats already possible with available apps or if we'd have to write something new.
