So here is my story. I installed a new digitizer for my broken HD2 screen, and ended up creating a crease on the ribbon cable. I managed to also break off half of the lock-in bar (the black bar) on the socket, but it still locks half of the other pins down and in place.
Heres the problem.
I turn on the phone, and the screen lights up but doesn't show me my display. The backlight IS on, but isn't showing the bootup, or anything. I DID manage to get it to show the screen by messing with the cable, but only for a few seconds and then it wouldn't anymore. The phone functions fine, I had a friend send me a text and the phone vibrated, and when I pressed the lock button it locked and unlocked (for my Android ROM). I know it did this because the backlight would turn on and off on the LCD.
Would buying a new LCD fix the problem or does that little black bar on the socket matter? I figured all it did was lock the pins in place so it shouldn't be a big deal..
there is 3 ways out of that.
One put a tape over the back side of the flex. it might work sometimes, but not reliable
Two buy a new socket from ebay and resolder it.
Three hardcorely wire them. It is possible I fixed a broken volume flex before.
the lock does not just hold the cable in place it also pushes it down on the contact face.
You may be able to pack the ribbon on the back to help it fit tighter in the sock & increase pressure to the mating faces, hopefully the rest of cable is serviceable ! extra lock security can be added with tape & ribbon can be reinforced with tape too if helps.
There are many of us in the Nexus 7 community who are looking to build our tablets in to our cars and other places where the power button will not be practically accessible. I am one of those people. I was wondering if anybody had any ideas on how to extend the power button?
The ribbon cable for the power and volume buttons can be seen here: http://www.ifixit.com/Guide/Installing+Nexus+7+Power+&+Volume+Button+Cable/9926/2
The header/connector on the board for the cable looks way too small to solder to and so my latest idea is finding a replacement ribbon cable that I could extend in to a tiny gauge wire and externalize from the case. From what I've been able to find so far, I think this is a ZIF FPC/FFC type ribbon cable and connector? I was thinking of something like this: http://www.mouser.com/ProductDetail...GAEpiMZZMvyL%2b65tEJ/L29YMZjxdjhiuZuU4IfHbXs= But I truly have no idea if this cable will fit? Anybody who's great with PCBs who would like to chime in?
If it helps I found a Molex catalog that has a couple connectors that look similar:

Ive been considering the nexus for my car pc aswell. Once i pick mine up i will tear it down and see if a ribbon cable could be either extended or possibly simply cut and have wires soldered to it for external power and volume. I have already designed a power supply for the nexus in the car that would also power a DAC and a HDD. I can provide the part number for the TI power chip that i used if anyone is interested. Its capable of producing 6 amps of current at 5 volts.
physical buttons suck. make all phone with only capacitive buttons,.

How would that make externalizing the buttons as needed in this application any easier..?

This is what I ended up doing. I got some good advice from another XDA'er who suggested I just pop the bubble button off the ribbon and solder to the contacts directly. In reality the bubble buttons are on a laminated sticker that I could just peel back. Then I soldered to the pads and pushed the cables out through where the rubber for the power button used to be. So far things seem to be working well, I'm a little weary of how this soldering will survive the swings in temperature being left in the car, but I guess there's only one way to find out. Observe:

Thats very nicely done. I want to do power and volume for my setup. Did the wire size you use work well or would you recommend smaller? otherwise i will need a separate volume control solution for the system. what do you have your tablet connected to for your amp and speakers?
Thanks. I used a 22 gauge wire, the smaller the better I think, as long as it's not bare. As far as amp, I'm using an aftermarket CD deck with a 3.5mm audio in. So I don't really plan on changing the volume on the tablet itself. I'll probably just keep it at 90% to avoid clipping and then adjust the gain with the CD deck. I haven't put it in my car yet though.
Steering Wheel Controls for Car PC
Has anyone tried the Joycon steering wheel control system with an android yet? It supports HID and no drivers are required for windows. It says that it cannot be programed from a linux or mac computer but just windows. Though once its programed it can be used with linux. Im thinking USB OTG plus this guy and you could control the tablet right from the steering wheel.
The solder will last fine on that job. The only thing I would be concerned about is getting false "presses" from the one lead that's soldered to the middle touching the outside ring. Perhaps just place a piece of electrical tape under it. Your other option might be to go straight from the connector the the flex plugs into. Just use a multimeter to test which pins you need to tap.
Thank you so much.

I just wanna thank the hell out of you. I have been searching and measuring that tiny little cable for about 2 hours now trying to find a connector and cable the right pitch/pins. Somehow the magical world of google brought me here. A site, despite my post numbers, I frequent very often. I'm installing the tablet in my car as well and I too needed a solution to the power button. Cant believe I didnt think to check here. You posted this just a few days ago. Crazy. Once again thank you. I should be able to pull this off no problem.

Oh and by the way any issues with this so far? I dont imagine you have seeing as a switch on the to ends of the wire are doing exactly what the little foil button does. Just wanted to ask though before I commit to this in a couple of days.
I recommend if you are going to put it in a car, it needs some sort of quick release. If any stress is put on that cable, the contacts would either lift or the flex would rip pretty easily. I did my nook soldered straight to the main board and a quick release in the cable between the board and the button. I also did as much as I could to keep the cable from the back housing to board from moving by putting tape and locking the cable down when I put the back housing on.
The first picture shows the main board of the Nook. I just took off the old button and replaced it with my wiring. I used hot glue to keep it from wiggling.You can see the quick releases I used in the second picture. I just pulled them from a donor PC I had laying around.
Being a USB fan, I'd try to see if a custom USB device could do the job.
Just recently I made a USB volume control for Windows.
It works on my Nook Touch too.

Exactly. I'm planning on using a male and female molex connector I found at radioshack. Currently I'm trying to figure out some intricacies involving Google Music and external storage but soon I'll have more pictures up here.

Have you tried connecting a faux USB HID device (like the Arduino Leonardo) and sending arbitrary keycodes while it's "off" to see whether any might be capable of waking it up? I don't know whether that could power it up from a "cold off" state, but I'm 99% sure you could wake it up from "screen off, asleep" that way.

I haven't tried this. I've just been using my externalized power button to wake the device from both warm and cold off states. I have a CNX-2140 power supply from my old car PC setup that has an ACPI pulse. I use this to wake the device from a warm sleep.
Thanks you XDA for being here. Just solved half of the problem my friend was having for his tablet . Mounting it in a 2006 Mustang. Now, Gotta see if he can use the POGO for charging and a USB OTG for the external camera
its help!! thanks!
What do you terminate the raw wire ends to now? I'd by looking at mounting some kind of button inside the cab of my vehicle to turn it on/off. What kind of button would a person look for? Thanks

I purchased a Joying single-DIN 6.2" head unit from aliexpress and am having two issues. When I first turned it on the display was completely scrambled. I let it boot & sit for a while, but eventually ended up hitting the reset button. I did that three total times, each time the display became (oddly) less scrambled. After the third, it booted up completely normally and I got to work finishing the install.
Once finished, I found the power antenna trigger was not working. No 12v from the stereo. I checked the fuse, then checked for power directly at the stereo connector. Nothing. I temporarily switched the amp-cont with the ant-cont wires, and the antenna worked but the amp did not. So, I'm 100% confident the issue is the stereo - not my wiring or anything else. The car happens to use ISO connectors, so there wasn't much wiring to do.
I dug around in the "developer" menu of Car Settings and found an entry I believe says "Antenna always on" or something like that. I tried enabling it, but the setting wouldn't "stick." Leaving the menu and coming back, the option would be off again. I unplugged the stereo entirely from the car, I hit the reset button a couple more times - got nowhere. I think I made a mistake when I eventually used the Android "reset to defaults" option. The display scrambled itself again. Here's the weird thing: While resetting, the car's antenna moved - I didn't see it, but I heard the motor run in each direction, up and down, in quick succession. Guess it may have moved an inch. After a few resets & key cycles the display came back up, but I was missing a few things - the "live" wallpaper and Torque, for example. I found the apks in the file system and reinstalled without incident. However, *still* no antenna, the antenna developer option still doesn't stick, and the display periodically scrambles itself. Much fun. Do like.
I contacted Joying, who politely offered to send a new display cable but informed me it was National Day in China and would be off for a week. So, maybe National Week? They asked if that was okay, and I let them know it is - I'm not pressed for time, it's no problem.
In the interim, thought I'd ask the brain trust here for opinions. It seems totally logical antenna control is just a software setting, so perhaps there's a fix. The display is more troubling, but perhaps a new cable will indeed fix it. Anybody have any opinions? Is it feasible to download a full Android 6 ROM (?) package and install it, see if a full rewrite fixes things? Something else?
Thought I should be polite and post the answer...
My display issue was a small internal cable connecting the mainboard to the display daughterboard. It was physically damaged, probably upon assembly.
The antenna issue was a VR on the mainboard was not outputting any voltage. Joying pointed it out to me and I verified with a multimeter. Probably a defective part.
I returned the defective head unit (was $$$ - price of buying from China, I suppose) and they promptly sent a replacement. The replacement did everything correctly, has been installed for a week now.
There are definitely some built-in quirks with these things which probably don't need to be reiterated here. Hopefully with some software tweaks I can manage most of them. This is all expected - the hardware works, and in my head that's all I was paying for anyway.
Now, to go find a better music player, launcher, and hopefully a simple way to actually shut the head unit down rather than sleeping it... this car tends to sit for a week or two at a time and the small (~.010a) draw puts the battery at risk over such long intervals.
Just out of curiosity, how much was shipping to return it back to them?
Did they offer to cover any of that?
Guys! Is there a way to control the antenna only when the "Radio" is switched on ? in my case the power antenna is extracted and retracted when I start or switch off the car. Not when using the "Radio". In my previous Kenwood unit (Non Android) power antenna was operated only when the Radio was used. Yes I know the Android radio is a software compared to the Kenwood unit. But there should be a way to operate the antenna on demand doesn't it ?

No, that is not possible. In these kind of android units the radio is always (!) switched on. The radio app determines whether you hear it or not.

I know this is an older post, but I am troubleshooting this same issue now. I believe this is (or at least should be) possible. Here are my findings from 3x different Joying models that I have tested.
UL135N2: Android 5.1? (This is the best/desired functionality)
* Power antenna extends when power on to the HU only if the radio app/tuner is active. (Turn vehicle on)
* Power antenna will extend when power on from pushing the volume knob (vehicle running with radio app active). Antenna also extends when opening radio app. Antenna stays extended when using home button instead of back button to switch to another non-audio player app. Radio app keeps running and antenna stays extended when switching to nav app.
* Power antenna will retract when power off from pushing the volume knob (vehicle running with radio app active). Antenna also retracts when closing radio app via back button or switching to another audio app (ie..BT radio, aux, etc.) after using home button while radio app is running.
* Power antenna retracts almost immediately when power off to the HU (Turn vehicle off)
UO135P4V: Android 8.0 (This is OK because the volume knob power at least controls the antenna)
* Power antenna extends when power is applied to the HU whether radio app is active or inactive (Turn vehicle on)
* Power antenna will extend when power on from pushing the volume knob (with radio app active or inactive)
* Power antenna will retract when power off from pushing the volume knob (with radio app active or inactive)
* Power antenna retracts almost immediately when power off to the HU (Turn vehicle off)
UO135N4G: Android 8.1 (This is worst functionality of all units so far)
* Power antenna extends when power is applied to the HU
* Power antenna will NOT retract when power off from pushing the volume knob (vehicle running with radio app active or inactive)
* Power antenna retracts after several minutes when power off to the HU (Turn vehicle off)

I am currently using a Toyota harness supplied by Joying. I plan to swap the amp.cont & ant.cont wires per some other posts to see if that might work. I found that the Metra 70-1761 harness seems to jump the amp & ant wires in the harness.
On another note, there are a couple settings (Antenna always on & Amp ON/Off) in the HU that seem to have no affect on functionality. I have reported this to Joying, but they "do not support this feature".
Hi all,
I believe that I am seeing the same issue in my Joying JY-UO138P4 radio as the antenna control lead never goes to 12v. Being that my car does not have a retractable antenna and only requires the power lead for the aftermarket adapter (amplifier); would there be any adverse effects to connecting the antenna control wire to the head units amp control wire and have it on whenever the head unit is on?
thanks,
dave

I don't believe that you'd need 12v on the ANT-CONT wire if you don't have a power antenna. Just connect the AMP-CONT to your amplifier and you should be good to go.

Sorry to bring this back
i dug into my car setting developer mode, where do you find the "antenna always on" option from?
I am afraid I have no recollection, but I might be able to poke around this weekend & let you know.
(As a side note, in case I didn't post it at the time - the problem with the antenna turned out to be the mainboard... I traced the circuit and found no output from the stereo under any conditions. It was eventually replaced.)
[SOLVED] TL: DR: Diagram show pink wire is for backup camera when the correct wire is brown as indicated by the tag on the wire itself.
I've had my SWM 8802 for about 8 months. I've always used a separate dashcam/backup cam combo, but also purchased a separate backup cam with an RCA output jack, and now I want to use it with my SWM 8802.
My head unit has a dedicated app from the home screen named AV In. Without anything connected (or connected but not powered, it just remains at the boot screen. Now my backup camera is tested and working. It has a power jack and an RCA jack. I tested this by hooking up a 12v 1A power adapter to it and an RCA cable from it to a TV, and it works. So with my vehicle I have the same power adapter connected to an extension cord. and it lights up.
The rear of my head unit has AV1, and AV2 (which I found out are video outputs), but it also has CAMIN and CVBSIN. Whne I have the camera going to CAMIN, and the AV In app activated, nothing shows up except the AV IN boot screen. However when I have the same RCA cable from the camera to the CVBSIN my head unit displays a red warning triangle with, "Viewing while driving strictly prohibited. Parking Break must be engaged to view." I don't know what the CVBS IN does, but if that's the only video port that works I'd like to find a way to disable that parking break sensor. Otherwise, why is the CAMIN not working the way it should? I can't have a backup camera if I have to have the parking brake enabled.
Attached is a photo of the wiring diagram that was advertised with the head unit. What steps should I take? The original RCA video cable has a red wire at both ends. What should those get attached to?
CAMIN is the input for the backup camera (CVBS camera - RCA plug).
CVBSIN is the input for the AUX AV IN camera (CVBS camera - RCA plug).
The backup camera will only display when triggered by the reverse gear signal... The pink wire in your image (PARKING SENSOR CONTROL) needs 12VDC when the vehicle is in reverse gear. This is usually connected to one of the reverse lamps at the rear of the vehicle (as is the power connector for the camera) so that the camera is powered up and the head unit switches tyo the camera input at the same time. The red wire in the video cable makes this easy... Attach the red wire to the pink wire at the head unit and connect the red wire to the power wire at the camera.
On almost all android head units, the backup (reverse) camera input is not available to the android operating system, so no android app can display the rear camera. The backup camera output is connected directly to the screen via the MCU so that the image is available even before the android operating system has booted.
The CVBSIN is the auxiliary in. Most unit require the brake wire (brown wire in your image) to be connected to ground before the image is displayed, for safety reasons. You can usually bypass it by connecting the brown wire directly to ground, or by selecting the bypass option that is available in the advanced car settings of most android head units.
That is excellent information! I wish that was included with the manual for all Android head units. I will try your suggestions and follow up. Thank you for this!
At first I tried the red wire to the stereo and no luck, only to come back and re-read the message and see that it should be a pink wire. I tried that = same.
Prior to this and after my first post. I had taken a terminal block and ran ring terminals to it. I hooked up my existing backup camera to it and it works fine, so I know those terminals are good. I ran new ones from the power connector + and - to the same terminals = still no video and no power to the camera. I made sure the car was on and the gear was in reverse. Perhaps I have to solder these ones on. Seems like the wires are a very small gauge for some reason. My alternative was to use an extension cord and plug that into the power of the camera, then test the video the Android head unit.
I just went ahead and bought a fuse tap, going to try that for the backup camera. I bought two, so if needed I can use another one to supply power to the camera itself.
I got it! It turns out that while the diagram showed the pink wire for the backup camera, the wire was labeled (or colored) wrong. I was out at my car this morning going to attempt it again when I traced the brown wire from the harness and it read "BACK". After some fiddling, I routed everything correctly including the powered RCA cable to a positive for the backup light, and the positive on the other end to the brown wire terminal. I started it up, hit the AV app, put it in reverse, and it displayed! So, it appears that when it down, use pink or brown to determine which one works.
I have a similar issue. My vehicle harness plugs straight in but its missing the cables for the brake. Is there a way of finding this easily? The cam works when plugged into the additional AV socket but so far can get it to work off the reverse.
Thanks.
Hello friends,
Today I received the multimedia system that I ordered from AliExpress and of course the frame did not arrive compatible with the car (as I was promised),
But I improvised and managed to overcome it,
The problem is that I connect all the cables properly and turn on the car but the unit just doesnt turn on,
Maybe I'm missing something and I don't know? I even tried replacing the fuse, but nothing.
In the video you can see everything, although in the video I only connect the power cable, but before that I tried with everything...
the system should turn on even when nothing is connected except the power cable, right?
I would appreciate your help because I am at a loss and the seller is not really helpful..

You should read the installation guide.
There are 2 power lines necessary to get it booting, and a ground to the car body.
There is a red one (mostly) which has BAT power at all time, and most probably a yellow one marked with ACC. This line switches the radio on when you turn the ignition key to on, so this line needs 12V from the ignition.

Use a voltmeter or test light and measure the lines Battery, ACC and Ground.
Battery should have constant power and ACC should be powered if the ignition is on.
What is about the missing connection here?
yanivos89
To add the may be missing information:
You don´t feed the unit with any power. There is a connector with yellow and red line from both connectors, but you need to connect the one from the Quadlock to the head unit cable tree with the same colors. In the second picture I think there is an open connector for that.
thanks, you mean these orange and red wires? i connected them but still nothing

I think that this connector does not fit your car
Connectors in green area are used for speakers. And metal connectors in plug (from vehicle) are present.
Connectors in red area are used to supply power [battery+, ground, ACC], buttons illumination etc. and metal connectors are NOT present.
Look at blue arrows for reference
What is cars brand, model and production year?

Do you have the same unit and cable tree?
I can´t see the counterpart of the Quadlock connector coming from the unit.
To get a proper answer, we should see both connectors from the front and the back.

No, those connectors are taken from yanivos89 photos - left is harness from his SEAT, right is from his android head unit.
There is no way to connect 52pin quadlock to 40 pin quadlock, even if plug physically it can be connected, the pins inside simply dont match.

Best you can do is contact seller and ask for new harness. You need 52 quadlock connector, similiar to rest of modern VW group cars
Volkswagen (2015-2020) WG8 Sensor-Screen Bluetooth Head Unit pinout diagram @ pinoutguide.com
Additionaly you need to know that in your case everything is highly dependable on CANBUS decoder - harness from your car doesn't provide ACC signal to wake radio or signal for buttons illumination. It is solved via CAN signals.
Maybe CANBUS decoder also has to be replaced if wrong harness was sent.
Ahhh... didn´t see that.
You are right. In this case he has a wrong cable tree from Ali.
thanks very much to you both! i will check this,
what about the canbus? also need to replace or it fit?

...but you told us, that you was aware that the unit does not fit your car, right?
Wasn´t that good your decision to buy a not matching unit, right? Makes it complicated to reconfigure that stuff.
In this case: I think you will have to pay for a harness and may be also for a new CAN box. Try to buy one from the seller, or:
You also can buy a harness for VW/Skoda/Seat and crimp it to the current harness.
In this case you need to follow the connection graph on the unit and compare this with a picture of the OEM connector. Should be found on Google. May be the CAN connector works, may be not. There are a lot of CAN boxes available for your car in combination with Chinese aftermarket radios.
Good luck!
I think your car is MQB platform and the radio is for PQ platform. 52pin qadlock to 40pin. Maybe a reduction will help you

the harness of the 52 pins did solve my problem, thanks everyone for the help!
