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.

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:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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.

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

SPRD Head Unit Problems

Hi....Attached picture shows what I have and the problem I am having is that it will about 30% of the time come on without sound and turning car off and back on will have sound and everything will work fine until I turn it off again. Car is a 2001 LS430 and have tried all canbus settings within the factory settings for the type canbus I have. I have tried sleep and non sleep modes, reboot the unit while car is on, reset while car is on, change canbus settings while car is on and nothing will bring the sound back until I turn car off and back on. The unit comes on to a different screen everytime and is not consistant in what it does. The radio in unit may play then switches to car tuner and then afterwards sound may cut off and this may happen also with the car turner coming on first. I have changed the car launcher with agama and sometimes the sound will play fine and when hit home button agama starts up and other times it is already there which it is supposed to be. It is very eratic how this unit boots up or comes out of sleep. Once on everything works fine including AC controls but did notice when messed up the AC controls still will work on app but not light up if turn fan up high etc. You would think the home launcher would be the first thing to dictate what happens but for this unit it is down the line. I have since put a switch in the ACC line to use so I don't have to cut car off. Has anyone else here experienced this. Is there a way to go into settings somewhere and dictate the sequence. I can get into factory settings with password but do not know the developer options password. Thanks and hope someone here can help with this strange problem. Like I said when it comes on it is random what I see on screen when it does and doesn't work.

I don't think this a FYT unit. Please run the HWGetInfo apk from my signature. That's the simplest way to tell whether it is a FYT.

Thanks...I did that and it is not an FYT unit...Where should I post this question...thanks

I have requested the Moderators to move this thread to the general Android Head unit forum
