Wondering if anyone can help me.
My unit has a back panel like this..
Well I had put an image link here to show you but being new here I'm not allowed...
The image of the back is in this post I think.

For the life of me I can't find connectors to suit.. I wanted to add DAB/DVB and Reversing Camera but not really sure what brand would fit these connections.
I'm UK Based... any advice?
Thanks very much.

New Screen - Sofware Problem???Please Help

I Have 2 No Early 2005 (with the cog shaped camera pod) M2000's which have cracked screens, i have now managed to get hold of a working late 2005(with the round camera pod) unit with a duff PCB and swapped the front half (screen and keyboard). When i swap this over all i get is a white screen, is there a software problem and is this compatable. I have checked that the front half does work by fitting it in a late 2005 working unit
Hope someone can help
with thanks

vogue with camera flash??

Just curious if anyone has attempted to add a flash to th vogue? I noticed the other day when taking off the back cover the little circle mirror thing beside the camera lens easily pops out, so i decided to compare it to my titan and noticed that it appears that possible a l.e.d flash of some sort could perhaps fit in there.
anyone done this, and if so can u explain what is needed (software) and where to get the flash bulb that can be used. Thx
The hardware needed isn't there.

cant. cant. c. a. n. t. be done. there isnt space for the flash bulb, and then you would have to think about where you would place the connections for the bulb. this is just hardware aspects of it, software side would be 10x as hard
Always bring a flashlight ! SOLVED!
actually if you look next to the speaker there is an external antenna connect ion there right below where the little door that pops out is... simply put it can't be done
You wanna keep that there for self portraits. Oddly enough after a year of having the phone i figured out that u use that mirror to center yourself or yourself and a friend when you can't see the screen.....

Android Car Rear View Mirror Owners?

Hi guys
Ive been trying to choose a dasg cam but im tginkibg abouthing about getting one these instead.
I'm just wondering how good they really are or are they just a gimmick.
Some things that really need to know are.
1. How good is the front camera as in the spec it says that it's only 30fps where as I would have preferred 60fps.
2. Would I be able to hard wire it to the car and leave it on all the time and then view it over wifi from my phone using an android app.
Other than these two things. I really just want to know how food they are and if the mirror is really a good mirror and not just a dull reflective surface.
And help would be really good
Anyone ??
If you left it on all the time it would drain your battery. But with a 12v adapter to micro use would be possible with correct wiring.
I don't have anything to compare camera to other than the other mirrors I own. Which they said where 1080p but really 720p. Only my A33x5 is true 1080p.
Mirror works like normally mirror. The new a33x5 screen is big improvement over a23. But still hard to see in sunny conditions
My use is really only recorder and google maps. If you need other features I would suggest something dedicated or double din. If you just want recorder only, then buy dedicated one for same price.
Thanks for the reply.
I have one of those battery savers that would cut the power before it would drain or damage my battery so I should be okay on that front.
But are you able to view the camera from an Android phone using an app (most connect using a wifi connection )?
Like I said I was really just in the market for a dash cam but I can see the benefit of a mirror with not only a dash cam but also a reversing, fm transmitter...etc
Help needed
Hy guys
I am in desperate need of help, please forgive me if this is not the exact place for my request.
I own a full hd rearview mirror dash camera, that also has 3g and android. The problem (until three days ago everything has excellent...) is that it got stuck on...upgradin android, optimizing app 1 of 1. I saw that this happens on android, but the issue with my mirror-tablet-camera is that IT ONLY HAS ONE BUTTON! So I have no volume up button in order to start a recovery mode or something. It has a reset button, but it is useless...in this case. I tryedkeeping the reset pushed 10 seconds, 20, 30, also tryed pushing iti while booting, tryed pushing the power repeatedly while booting, keeping the power pressed 10-20-30 seconds....nothing helped!! Any idea? Help? Please? Thank you.

Wifi Bluetooth Antenna problem with connection

Hey guys,
I have a problem with my OP3. I dropped it and it had a big dent on the back. So I decided to open it an try to press the dent back into shape.
After reassembling my Wifi and bluetooth are broken. I can get connections but the range is realy bad, about 5m for Wifi till it disconnects and about 5cm for Bluetooth.
I opened it a second time to take a look if i missed a connector or something and i saw a clip (those small things that connect to the back of the phone) was broken so i ordered a sparepart (it was the headphonejack circuit board) and changed it but its still not working.
Does anyone know where the bluetooth and wifi antenna are positioned ?
Have i just broke my phone or can i change something to get it back to work ? Everything else is working fine.
Thanks in advanced
Dennis
Same problem here! After I replaced the screen I lost my WiFi and bluetooth connections as well. WiFi is working in a range within 2m.
Is changing the coax antenna cable a solution?
Many thanks in advance from me as wel
Ken
Glad I'm not the only one, so maybe we get more help when more people have the same problem.
I changed the backplate cause of the dent and because the antenna is built in there but didn't change anything.
I have ordered a coax cable and will replace it when it arrives, could be today. Will post afterwards if this helped, but I'm not realy confident in that because i haven't done anything with this cable while repairing.
Maybe someone knows more about this, i just don't get why it is working but has no range, makes no sense to me ...
I have opened my phone several times now, but nothing seems to work.
Do you have an update on the coax cable yet? I hope it works, or the one plus 5 has to hurry ?
Hey there, same for me, opened it up to 10 times now but nothing helped, coax cable was a failure too. I realy don't know what it could be.
I'm about to wait for the OP5 or get a used 3(T) depending on what the . Was thinking about getting one with cracked screen and change everything but not sure if i should try it.
I have the same problem now. Any updates?
Hi guys! Yesterday I changed the camera of my OnePlus 3 because it wasn't focusing anymore, after reassembling my phone I noticed it wasn't connecting to the wifi anymore, tried Bluetooth and it was the same problem... I had to be really close for it to connect
Did any of you had any luck solving this problem? Did changing the board in the bottom of the phone not solve it? It seems that's where the WiFi is... Or maybe changing the backplate
Thanks in advance!

i also have same problem , need fix
Anyone found a solution? I had the same problem when I replaced the fingerprint sensor + the battery
I've been without wifi for 4 months now... Any help is appreciated
Hi, guys. I have the same problem. Did anyone find a solution?
I replaced my rear camera and the loudspeaker, at reboot wifi was not working. I noticed that if I'm near the access point network is detected but with very poor signal strength. Thanks.
Hi, maybe I could have found a possible reason to our lack of wifi and bluetooth signal.
Please look at this thread and give me your opinion. Probably your mainboard shows the same problem.

PX30 Screen Issue white where black should be - HW or SW issue?

Picked up a used PX30 with a funny issue that I think might be HW related, but just want a second opinion before I do anything.
It is like it displays white where a shade of black should be, see attached picture, is this HW?
Model: ICE/HU/IN9053BL
Thanks for reading

It is a MTCE_LM_V3.42_1
I would venture that it's software. The reason I say this is that the colors on the ruler for the reverse camera are correct. I believe there are display adjustments that you could try in the factory settings. perhaps. Or it could be as simple as maybe in the accessibility settings that it's set for high contrast.
Maybe a factory reset might be something to try first?? Also are the colors jacked up when the system reboots like for the Android splash screen?

The unit had been reset when I got it, but can not hurt by trying again.
The boot splash also has the issue on the animated logo, and it moves with the animation.
Before I do another reset, I will try to changing options in the factory settings, think it is the Display LCD type option i need to try changing, it is my first android head unit, but been android user for long time so will try flicking options and if all goes wrong a reset it is
It's wild that the ruler colors (red yellow and green) on the reversing screen were correct but nothing else is. Wow. If it's happening on the Android boot logo, that's kind of before Android has even loaded so maybe it's not necessarily software. I was kind of hoping maybe if logo was correct then something was getting flipped after boot up.
The color and display settings in the factory settings, I would think would be applicable regardless of whether Android has booted or not since those settings typically change settings in the MCU or main board.
Sorry for putting out more maybe's than answers. Hope you can get it sorted and report back what the solution is.

Mate, nothing to be sorry about, very grateful that your reading and trying to help
I 100% agree with that it might be some setting that can change the MCU or MB, but still have a naging feeling it is HW, so after work today, I wil take the unit out and take it apart and see if i can "see" anything, maybe a loos connection or something.
I did look in the factory setting and it does not have the color settings, its android 9.. So maybe custom rom and if problem still there then take apart.. Hummm..
I will share with you that the TFT board used by Dasaita is one of the many weak points of these head units. That's the board that has ribbon cables between the main board and the display. I suppose it's not impossible that one of those ribbon cables could not be seated properly.
I got Dasaita to send me a replacement TFT board for one of the units that I installed in my truck. It got the display going again but unlike your issue the backlight wouldn't light up. I found the actual component on the TFT board that was smoked. There is a zener diode that is used to control the backlight voltage. It overheated as a result of having the screen brightness at 100%. Interesting that they set the brightness to 100% from the factory, imagine that...
Those ribbon cables are very cumbersome to get seated into their sockets and they didn't leave but very very little slack to work with.
I just find it odd that the colors for the ruler on the reversing screen are correct. The color settings I was referring to before should be found under the "other" category across the top in the factory settings. You might need to scroll down that list of settings to find them. Also the factory settings are not necessarily tied to the Android version. Those are tied to the MCU firmware version. If indeed your unit does not have these settings, it could be one of the differences between your PX30 and my PX6. It's possible these might be made available on your system using an alternate password instead of 126 to get into the settings, but I have no idea what that password could be.

Hi Friend, were you able to solve your problem? I have the same problem with my PX-30 multimedia. I'm thinking about opening it and seeing if the cables are connected correctly. Did you need to change something? or can I change the factory settings in CAR?

Hi mate, I have not been able to fix it. The only thing I "did" was to unlock the factory settings and looked around in there, but was unable to see anything that might help. Also I did take the unit a bit apart to check for loose cables but did not find any. My next step is to install a custom rom "just to see" if it is a software issue or not.
How did your problem come about? Did it just happen one day?
6 month of use? is that from new or second hand? Or was it just in the car you bought?

Thank you for the clarifications.
I bought new on aliexpress in March/2021 it worked fine until 3 weeks ago, suddenly for 2 days it was alternating the color "Normal x negative screen"..
Right from the start I suspected some HW problem, since in my neighborhood, there are many holes and the car shakes a lot.
Right now I'm talking to the seller requesting permission to disassemble the multimedia and see if there's anything loose.
I have a hunch that it might be something in FLAT or BGA since the car is in the sun and several times when I got into the car I saw that the screen was super hot (even off)
As soon as I move forward, I'll share it here with everyone.
*I'm sorry for my English.

Thanks for the info and update mate, I hope you have luck with them giving you permission to open it and check.
I might do that with mine again as I did not take of the circuit boards, just took off cover and checked LCD cables.
Will also post updates if I do make a 2nd attempt and good luck with yours.
Your English is all all good mate, nothing to think about

If your unit is Dasaita, no need to ask them for permission. It is common practice for them to provide replacement parts for us customers to "fix" issues which most often requires opening the unit. The warranty on these units is for the most part worthless as it would cost more to ship the whole unit back to Dasaita than it's worth as they typically expect you to pay shipping cost both ways. Just saying.
The seller returned me and asked to do a firware update, I performed the procedure he instructed me to do, but it had no effect on the screen (I just noticed an improvement in the audio/equalization)
I'm waiting for the next steps, they asked some more day to evaluate with the manufacturer.
Hope that they can resolve the issue to your satisfaction. Please keep the community here updated.
