BMW e60 PX3 android - no signal on OEM side - Android Head-Units

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

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.

PX6 13" F-150 Bluetooth Bug/ Volume Muted. Not Able to Reset to Factory Default. Update Firmware?

Hi All, In November of 2020I bought a Tesla Style radio for my 2013 Ford F-150.
https://www.aliexpress.com/item/4001084034182.html?spm=a2g0o.9042311.0.0.52474c4dpUsOsY
It had manual AC controls as pictured.

I got the install finished as pictured and the unit worked pretty well. It had the occasional bug, but most were corrected with a few button pushes on the screen.
As of Yesterday I have no volume control on the unit or steering wheel. The volume indicator shows muted with the red circle with a line through it as pictured. The radio no longer works and you can no longer get into the Bluetooth. Although the Bluetooth does continue to link to my phone , it makes and receives calls at a low volume with no volume control. From what I have read this is a Bluetooth Bug that happened when the Bluetooth did not complete it's reset after a call. I was on a call sitting in my truck, the caller ended the call and I shut the truck off ( I am guessing before the Bluetooth completely reset). The next time I started the truck is when the problem started.
I have tried disconnecting the battery overnight, Pushing the Reset with a Paperclip and Trying to do a Factory Reset to the original defaults. The first two resets did not clear the problem. The Factory Default Reset does not Factory Reset to default as it should. It just does a soft restart like the first two.
If I go into the settings there is nothing in any menu for the Bluetooth. I did read that initiating Bluetooth Call and then hanging up once the call connects will sometimes fix the bug. In my case it did not.
I have also read that if all types of resetting fail to fix the issue you can reload the firmware to fix it. Now back when I bought this unit I had done lots of research and it seemed that the problem people were having in reloading the firmware was getting the correct firmware for their unit. So when I purchased this unit I had the seller give me a copy of the firmware. But I got no instructions on how to install the firmware. Most Youtube videos I have watched are very hard to understand what is being said. So I want to know how to reload the firmware correctly.. I really don't want to completely brick the head unit. If anyone knows of this Bluetooth/Volume Mute problem I would appreciate any help. Here is info on my particular Head Unit as well as the Firmware Folder and Contents..
Any ideas would be greatly appreciated.. Thanks in Advance, Chris
I have tried quite a few methods of getting into the recovery mode, but non seem to work on this model. Does anyone know the correct method to get into recovery mode?

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.

What is head unit. Post Android system information including MCU version.
Thanks for trying to help

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

Trying to get flashing and blinking on a Topway TS7

Hi Guys
I had a 2007 Mini Cooper Chilli with a non-functional radio, and went through the tons-of-fun disassembly and removal of the unit to put in this TS7 Android head unit with a view to running wired Carplay. The good news is that the onboard Amp is still functional, and I have a partly disassembled dash, a bucket of trim screws, and surprisingly good sound, with WiFi, GPS functional and playing MP3s from a USB stick in an unpowered hub.
My approach is to get everything working in Android mode first (using the house WiFi to access the internet), make sure I have a backup, then try to implement Carplay using TLink5, so idiot's guides to the best practise would be much appreciated.
The bad news is that there are a few weirdnesses - the unit currently starts up with the seat indicator lit, an alarm ringing which either times out or can be reset with the emergency flasher (go figure), but thereafter none of the arc of indicators (things like fullbeam) work, despite the speed and fuel arcs being lit and functional. So I suspect the CANBus mapping.
USB may be a little flaky (and was with only a USB stick prior to the hub) as it seems to want the stick pulled and restored after startup to register it. Running two cameras in a Mini is probably overkill. The front camera (on the 6-pin USB port) seems to have gotten over a snit whereby it refused to admit the SD card existed, then disappeared itself; video for the rear is working whilst I mount it - not sure if only one USB port can be used at once, in which case Spotify is fine rather than a stick - hopefully the front cam continues to record to its SD card. There were some internal plugins between the display unit and the head unit (unless I fell victim to 'the cable fits, so plug it in syndrome'. I tapped the reverse line to present to the camera (may need a relay) and glued and powered the dinky fan (we're tropical here).
So, back to the indicator lights. I updated the MCU (the main software was up-to-date), and I have the access codes, but when I look for the appropriate car, I can't find it (and have no clue what the 00 General; 03 Simple Soft; 13 Binary; 02 Raise etc mean or do). Mini Cooper should reside under BMW - any clues here? Getting hardware indicators running is probably a more tricky operation then mapping steering controls (the left-hand cluster and phone controls are fully functional, although the other set is not).
Many thanks in advance
Neil

Just a quick add: looks as though the audible alarms were door and seatbelt, but when things change (lights on for example, I get a pic of two seats back-to-back, rear seats and a lock, and an AC setting bar. Also the photo shows the unit style - I have the 2G/64G TS7.
