BMW e60 PX3 android - no signal on OEM side

Hi all,
I've been going through topics for the last 7 days, but with no results for my problem.
I have 2nd gen, PX3 7.1 , 2G rom android headunit, i've bought it as second hand.
Android part is working good, no issues, but i cannot get signal for OEM i-drive side or for when reversing.
When i put in reverse nothing happens (i guess there should be camera view with no-signal and PDC display, right?). This is happening from the very start, so while in my car, this never worked.
I get sound from android unit, and all of the features there work.
I-drive wheel work on android, steering wheel buttons work on android (i am able to switch sources Radio, CD, AUX via steering wheel button), also signal is sent to dashboard app (speed, door open, brake pull..)
But, when i try to go to "Car info" or pressing MENU button for 3 seconds it always displays "No Signal"
What i tried so far (in chronological order):
-tried pretty much every CarType option in factory settings menu - no luck
- removed unit's back-cover to inspect hardware (i am not very knowledgeable about electronics, but connectors seem ok visually)
- MCU update to latest - successful but no change
- ROM update to px3 7.1.1 20181124 - successful but no change
- tried again original CCC i-drive screen with original harness - everything is OK, signal is there
- Did Factory reset - successful, but no change for No signal, i am now facing with Google services stopped error every 10 seconds, i will deal with that now, i will try to update services or downgrade to 20180703
Does anybody have any idea what can cause "No Signal" issue on OEM side?
What should i look for, what connector is responsible for that part?
Can it be faulty harness? Can it be software related?
I hope someone can help me, i am really struggling to fix this (if it is possible).
Thanks in advance!
Regards,
Novak

Ok, since nobody replied i will share info hopefully to help someone else.
I ve solved the problem. in my case it was Lvds connector/jack on the headunit itself. It seems that connections to the chip next to the jack were not good. Solved by removing connector and soldering new one.

The same problem
nowaq111 pls give me more information about this becamuse i ve have the same problem

In my case it was the lvds connector on the android unit. It had loose (broken) pins, so i took it to repair shop and they soldered new jack (new pins) and it is working fine ever since.

Help with Raise canbus settings on Chevrolet Trax (Europe)

Hello everybody from Italy,
Can you please help me with this issue? I've just purchased an Android 10 AllWinner head unit, had it installed but the original rear camera, parking sensors, beeps, etc are no longer working. Before everything was great on the original MyLink.
I've attached pictures so that you can have a look.
A Raise canbus was sent together with the car radio but even if it is set to CHEVROLET TRAX, it is not working.
Anybody knows how to help for this GM car? THANKS

the sad fact about getting a aftermarket unit that's not specifically made for your vehicle is that you won't be able to get any of those things working especially if they communicate through proprietary connectors and communication methods. You might be able to get the camera working through some special wiring and wiring diagrams. Other than that I doubt you will be able to get the ultrasonic parking sensors working with a basic aftermarket unit by itself.
And on another note if you had somebody install it other than yourself it will be even more difficult getting it to work. Being that you have no knowledge of what's going on behind your dash right now

Hi,
My android head unit has no option for GE - Trax.
I set the can bus to GE - Aveo. I use Raise can bus.
I mis plugged the connector on head unit side upside down, but after fixing it works fine.

Suggestions on new aftermarket stereos (Skoda octavia mk2)

Hello! I own a Skoda Octavia mk2 2008/2009 and I would like to upgrade the stereos in it. Current ones do not include bluetooth, but thats something I would love to have in it. I have thought about android stereos and something else, but seems like android would fit best? What do you think? It should work with all dashboard buttons the default stereo also works with. I have seen multiple different chinese brands in aliexpress, but I'm not sure which has the best sound quality.
My current stereo:

Now to the real question:
What stereo would you suggest for ~150-200€ budget WITH bluetooth? Would be awesome if you also knew that it would 100% fit.
Thank you!

Hi, i bought this from European site for 85$:
https://www.aliexpress.com/item/4000046636557.html?spm=a2g0s.12269583.0.0.4c041ae9COaKGp
I was quite surprised, it works quite fast, it is just sleeping (not turned) but does not draw much power when off (just like sleeping tablet).
Wheel buttons work, radio has strong signal. This version has only 1gb of ram, it is enough for preinstalled software but fe waze or spotify is a little slow.
Preinstalled Sygic works great but does not provide traffic info.
Beware different frame size as seen in picture, i bought used but if you are not as lucky, new costs around 1000CZK.
I also installed this launcher:
https://play.google.com/store/apps/details?id=altergames.carlauncher&hl=cs
I am sure you can find even more satisfying radio for 150+ USD, there are some models with 4GB ram and Android 10.

Is there any models you suggest for 150+ USD? I can't really find any.. :c

Hard to suggest something i am not familiar with, try to look here:
https://www.aliexpress.com/wholesal...&minPrice=120&maxPrice=200&page=1&groupsort=1

Take a look at this:
https://www.erisin.com/erisin-es272...b-carplay-for-skoda-superb-octavia-p0542.html
I have a unit for Mercedes and I'm very satisfied.

I bought mine from Pumpkin and its ok.
Make sure to buy a unit which will be delivered with an can-bus adapter for Skoda|VW!
As your car is a before-facelift model, be aware that not everything will work (parking distance, changing climate).
Also keep an eye on the battery, because on this building year the new radio can drain the battery empty.

In reality, you aren't going to get a reply because nobody has a clue what you've done. Post a video up of the failure and perhaps you might get a response, but in reality, you've done something right weird here, haven't you? I mean, who cleans their head unit.... just wipe the screen and be done with it.
Did you plug the old ribbon connector in while the unit was switched on? If so, my best guess is you've shorted something which is why your ribbon cable melted. Potentially what you've goosed as a result.... is a mystery.
Could be the entire screen, could be the entire unit, could be neither...
Might be time for a new one.

Might be time to find a local electronic repairer.

Bought this radio for my 2021 Toyota C-HR XLE, because i need rca outs for front/rear/sub as im running a 5 channel amp. BUT STILL HAVING A FEW ISSUES.
1. First off it doesn't fit all the way into the dash, sticks out about a 1/4 to 1/2 " all the way around. had to put a strip of blue painters tape across top of unit to keep it from falling out while driving which works. Looks like the outside tabs on bezel seem to align up with dash slots, but something is keeping it from locking into place.
2. audio cuts out when reversing. - i found the option to turn this on/off, but no matter which way you set it, it still cuts audio off.
manufact. said they will send a different canbus ? the one they sent me has alot of different settings, they told me to use xp for canbus type, but after trying every single option under xp/toyota nothing fixed the issue. so will have to wait to see what they send.
3. OEM rear camera does not come on. car switches to camera view when reversing, but nothing shows. they sent me a diagram to follow, but that didnt work either, and since that they keep sending me diagrams for connecting the included cameras but nothing to get my oem one to work.
Steering wheel controls started working as soon, as i connected canbus, so didnt have to do manual setup, but i think today, i may try and remove canbus to see if it fixes the reversing/audio issue, if it does, will see if i can manually add the steering wheel controls back or not. probably going to be a waste of time, but figured i'd at least try and see what happens.
If anyone else with a toyota c-hr has ahad any fixes for these issues, please post what worked for you. - many thanks
