I have recently replaced my head unit
Everything works on my unit, but the USB camera refuses to work with any of the available dash camera apps
I have installed a basic USB camera app and I can see the input from the camera, so it seems the other apps, simply don't recognize it
I had the camera installed on another MTCD unit and it was working perfectly well
I suspect there is some configuration that is telling android to use a different input, so I have manager to get to the hidden menu and there is a field for DVR, and changed it from the default (0) to 1, then to 2 then to 3, all to no avail
This unit is an Android 6 unit with a quad core with 2GB Ram

I think this is what you need to do if you have joying.
Unfortunately there is no option to put "USB", the only options are numeric, starting from 0
I already tried 0, 1 , 2 and 3, but no joy
The unit looks very much like joying , but it isn't
I have asked the seller and they sell a compatible usb camera, but it has its own sd memory card to record.
What's the point of having a camera connected to an android unit, it is has its own local storage? You may instead have bought a separate dashboard camera
Anyway thanks for the suggestion
usd dash cam ?
I have heard this first time.

1. HD+ video recording is a very CPU consuming task, one would not want to have his/her HU stalled. So let the daschcam use its dedicated CPU and local storage SD to do the task.
2. The point of having a camera connected is (as implemented by Joying) being able to output video on HU display, both live and stored on cam's SD - very handy; connected Joying cam (which does not have own battery) also takes time from HU to stamp video. Other brands are even able to take GPS coordinates from HU.

Because you do not know how usb works.
HD-video is not only CPU intensive, like ste2002 already mentioned, but it can flood your USB channel if you use raw video and encode it on your android unit.
USB-2, as on ALL android units is "half-duplex", meaning that only one device can use it at a certain time and only in one direction (like a walkie-talkie: only one can speak and you press the button and say "over" (as handshake in digitial language) to let the other speak). If you have 2 devices with your dashcam recording, and the 2nd one polls the usb hub, your video stream is interrupted and thereby immediately corrupt. Or the unit needs to send "something" to the dashcam, it will also interrupt and corrupt the video stream.
The option of encoding it on the dashcam and send the video over USB to the unit is better but not fault-tolerant.
encoding it on the dashcam and saving it over usb directly to your unit, might work but could still run in above mentioned problems.
encoding it on the dashcam, save it on the dashcam (internal "mini"-storage), and then copy the complete video over usb to the unit might work well. These dashcams might even be for sale, but I expect they are quite expensive, whereas a local sd-card in the dashcam is dead-simple and dead-cheap.
Once USB-3 gets to these android units, being full-duplex and having much higher speed and bandwidth, it might be useful to do it over USB (making sure all devices are USB-3 or that you have a real switching USB-3 hub), but only if the CPU can handle the HD raw video and encode it: A PX3 can't, a PX5 can't, a Sofia 3GR can't. Wait for much faster units (specification wise both the PX5 and Sofia 3GR should, but both fail on it).
That is why you should ALWAYS let the dashcam do both the video encoding and the storing of the media files, and NEVER over the usb.
Edit: With the Joying, and a lot of others, you can view back the movies, or get an online view where a MJPEG stream is displayed on the unit.

Surfer63,
Thanks for this post, it's one of the more informative ones I've found when searching for answers about making USB cameras work with these Chinese head units. I'm replying because while I'm far from an expert, my experience does not seem to follow some of what your wrote. In my case, I have an ISUDAR brand PX3, 2GB ram using a 7.1.2 "GS" ROM and have successfully used a UVC compliant 1080p USB Camera (Logitech C922x Pro Stream Webcam) and was able to record no problem using the factory supplied app labelled "DVR". The camera has no built in storage, and the only storage option the DVR app allows requires the file to be written to an attached USB stick (my unit has no SD card slot). Both the camera and USB stick are plugged into ports labelled USB 2.0. Overall this seems like good news as it's more successful than most have found.
For me, however it's still not success and I hoped you could shed more light here. My main goal is not a DVR, but to use the camera to record videos by other apps, such as Torque or TrackAddict. These apps support USB cameras and work fine with my Logitech and OTG adapter on my phone, however on the head unit it only partially works. When opening both Torque or TrackAddict the video displays properly in preview, but once Record is selected it either appears to work but does not actually capture video (Torque) or immediately gives an error "recording failed to start" (TrackAddict). When attempting playback from Torque you hear the audio, but the screen is a static mess of the actual image and various green hues and lines.
From this almost successful experience I am trying to determine what is likely not right, and if/how to check and correct. A few thoughts:
1) I know little about the Android inner workings, but reading some android camera API developer info I'm wondering if the ROM has the MediaRecorder aspect "hardwired" to only the DVR app. In my simple view this could explain why video preview works in other apps but recording does not.
2) In Torque you can select which camera to use, since the unit has no built in camera Back 0 doesn't exist and is not in list, Front 0 doesn't either but is in list (shows nothing). Front 1 shows the USB camera and selecting this makes preview work in the app. Interestingly the list also shows the USB camera by name, but when selected crashes the app. Is the head unit seeing the USB camera, assigning it to Front 1 in the background, and also forcing some record settings to USB stick and DVR app? If I could stop the head unit from automatically assigning the USB camera to Front 1, perhaps selecting it by name in Torque would allow it to function properly and record? I have not found any option in the Factory Settings menu to affect this yet.
Anyway, given I feel a bit closer to success than many on here I was hoping for some guidance on what to chase and how. Your insight would be much appreciated.
I'm struggling with similar issues with Eonon 2170 Android 8:
built in DVR app seems to work when it works, though, often stops recording (red light on USB cam goes off)
Torque's plugin just crashes... even though it's supposed to support USB cam
got somewhere with Dash Cam Travel – from Tomas Valek, dev promised to look into this
and, getting results from USB Camera - Connect EasyCap USB WebCam ShenYao China

I just updated from a KitKat unit (4.4.4) where the dash cam apps all worked with the USB camera just fine. I have a Allwinner T8 unit and the USB dash cam is not seen using the apps I have.
The apps that I got from the play store now uses my backup camera for the forward camera, but the supplied Dash Cam App works fine selecting the USB camera.
Trying to figure why the USB selection on the apps refuse to select USB while it always selects the backup cam (video source)
I have even disabled the backup and those apps will not work at all.. I will try the Dash Cam travel to see.
I can't help much with the main question(s) being discussed here but I have one of those standalone USB powered dash cams in my vehicle. It's just a totally generic Chinese eBay one.
It records directly to an SD card on the camera itself and broadcasts a wifi signal so that I can manage/view the feed on a (very unstable) app on my iPhone. The app is called "WCVR-PWD".
I've always wondered if there's a way to just view it directly on the Joying itself an sounds like some of you guys are doing that. All I'd be interested in is a totally live feed to adjust the camera as necessary.
What app/mod/function do I need to do to the Joying to do that?
As most? the head units have multiple inputs:
rear camera video in
video/audio in
USB
any experts care to comment on suitability or pros and cons of using composite video output camera versus USB camera?
Would composite output video camera be a superior choice?

How did u solve it then .?
conclusion for dvr with SDCard?
Hi
This is a good summary and helpful since a lot of info on google seems outdated.
I have a new Joying 8 Core intel unit (Nov 2019).
I want to buy a small non-Joying DVR camera, record to sdcard in cam, and use the head unit to review video from cam and manipulate the files as required (ex. send an important video or image).
Will the Joying do this for any cheap DVR camera?
Do I just need to use a different DVR app on the head unit?
Thanks!

I do not know if the joying will do this for "any" DVR camera. That is an extremely wide area.
90% of the Chinese dashcams are the same and have more or less the same app. I did not hear yet about issues.
Some dashcams come with internal GPS location logging, some not.
Some apps allow you to view the videos over usb, some/most allow you to copy the videos over usb to your local unit drive.
I use my dashcam as well for Mapillary recording. That results in big amounts of data and I simply take the sd-card out of the camera and do it on my laptop. I have two SD-cards which I simply exchange. A 16-32 Gb-sdcard costs something between 6-12 euros (in the Netherlands). Note that any class 4 or better will do. You don't need extremely fast cards.
What I have also noticed in the past (with 2 dashcams, so statistically perhaps completely unreliable) is that most cheap dashcams simply stop in the middle of a recording when being switched off: no battery whatsoever to nicely finish the recording and nicely unmount the sd-card. This leads to lots of minor corruptions. So when I switch SD-cards, I always do a "checkdisk" on the SD-cards and I always have to repair errors. Be aware of that.

I recently got an ATOTO A6 Pro and have been frustrated trying to embed GPS in the dash cam files. You mention that, "Other brands are even able to take GPS coordinates from HU." Which brands would that be? ATOTO has not been able to help. They just say it is impossible.
I have an Xtrons PX6 Android 9 headunit with cheap usb dash cam. The cam itself has micro SD card inserted and usb plugs into my usb on the headunit for viewing.
I have bought 3 of these cameras 2 to use in different vehicles and 2nd new Xtrons cam to go with the PX6. All of these cameras generally have pre-installed APK on the camera to install on the headunit.
You'll also find that these cameras have GPS and eDog built in aswell as ADAS. I purchased 2 of these cheap Chinese units from eBay for about £15 each and they work perfectly.
The advantage of having the camera record is that if the headunit goes down you still have the camera covering your ass if theirs a problem.

Sorry to hijack this thread.
Does anyone know what might be the problem when GPS signals lost immediately right after an usb camera plugged in?
The signals came back once the camera were unplugged. (the camera functioning fine, apart from not detecting gps as they're all lost)
Would it be a fault of the camera or the head unit itself?
USB thumbdrive works fine though, no issues.

Hello everyone
Because I came in looking for a solution to a problem with a camera for my car that has a "head unit", I come to ask my question. The "head unit" is isudar px3 with Android 7.1.2. I bought a forward camera that works well on a cell phone with android 7 (and with OTG adapter) without problems and on the date of its correct recording. When trying to put it in the car through one of the USB ports (there are 2 - one that I will say is normal and the other prepared for 3G/WIFI) and after installing the .apk that comes with the camera, it tells me that there is no card and that there is a problem with the USB, as if it did not exist.
already tried several .apk but none can connect with the camera.
During the time that it is connected, the card in the usb case records image and sound although it does not show anything on the car's media player screen, but these recordings show a much earlier date that has nothing to do with the moment in which it is recorded. That date will be that of the camera itself a few years ago. If the date was correct, it would still leave the camera in its place and for the least. But as it does not, its validity in case of an accident will be very weak, obviously, and so it is not working. Having asked the question, I ask for the opinion of someone who has had the same problem and has solved it. Thanks in advance.

I've been doing a lot of research and am now wondering if it's even possible to attach multiple external cameras to a rooted Nexus 7 (2013 or 2012)? And the next step would be what software (app) to use to display at once?
I've seen plenty of threads where one external back-up camera is added, along with some other attachments. And a few where the Nexus is attached to one webcam.
This is for offroad auto use, in a temporary (on the go) install with the Nexus in a mount. I would like to have multiple permanent external cameras in the front and one in the rear. Four would be great, but even just two would be useful.
I've seen it done with an independent multi display screen, but not on a Nexus 7.
Any ideas or directions to head would be helpful.
Any help, pretty please?
I'm stuck.
Unfortunately, I do not have a way of testing this as I only have one compatible usb webcam. However, I am inclined to think you can do more than one as the device should list them separately. Then, using some app to view the camera (I use Mirror), you should be able to switch between them. I know for Mirror, they are listed as camera 1 and camera 2 though I would imagine that you can add camera 3 and so on. The only issue is I don't know of an app which can display multiple, simultaneous cameras nor record from them. Best I can think of is manually switching between them, one at a time.
If I can get my hands on a second, cheap compatible cam, I'll test this out and post the results. I think you're biggest issue is finding something with multiple camera display.

Technically yes! with every new camera the device would be able to open a new stream at /dev/video* , as long as you have ways to capture it through apps you can. However don't take my word for it as i am equally N00b. Let's wait for the seniors to answer
Thanks for the replies!
I just looked for Mirror app, but there a tons of mirror apps for checking your makeup. Can you tell me more specifically about the app? Who makes it?
When it comes to software and what apps to use, I've figured out different apps work with different usb webcams.
And I have seen some apps that allow you to do 2 webcams. Not sure about a split screen though. Then again, webcam specific apps (only works on 2-3 webcams).
As far as what type of camera?
Usb webcams, check. This is going on my front bumper, and if I could have more than 2, then they will be in the wheel wells. But how easy is it to make a usb webcam weatherproof? I'm sure that's a different forum.
What about CCD cameras? Would it work just the same I if I got a "bnc to usb" converter or a "rca to usb" converter? Then basically hooked the usb converter up to the hub or Nexus?
Can I use this ____ (Google: 4 Channel DVR USB 20 Video Capture Box with Audio) and directly connect it to an OTG-Y cable?
Or do the CCD cameras and the usb webcams produce different video streams (not sure if this is worded correctly)?
Will be keeping an eye on this thread for sure. I just got done with my dash mount and was looking to do the same thing. Mount a camera next to each rock light for when crawling.

Well it seems that we are at the same stage of our projects and running into the same questions!
I just mounted the nexus in the Jeep and now I'm wondering if I'm just gonna have to use a single camera on the bumper and nothing else.
I'm still curious if any of the RCA type cameras will work with a usb converter. Has anyone had any success with those?

hi
did you tried "usb camera trial" app of infinitegra? as far as i know the app supports two webcams. i didnt tried it because i have only 1 webcam.

Posting this so I won't forget and maybe it will help someone else out about hardware of different types of cameras.
RCA type camera - THE EXPENSIVE ROUTE (but already waterproof?)
I did some more digging and found where someone tried the EasyCap with a webcam on a Nexus 7, and it doesn't work. I looked at a bunch on Amazon (other different brands) and they all have a CD with drivers. So that's a no go, unless I could embed the certain driver to a custom Rom (way over my head). The 4 channel EasyCap video grabber says it can only display one at a time though, if it did work.
The only Video Grabbers that work without drivers on Android (that i could find) are these two -
OPR-HD879 UVC USB AV Android Capture Card
FEBON 100 USB CVBS UVC Grabber Card
These aren't that cheap (about $50 and $80 w/o shipping).
There is also a FEBON 188, which is a SDI camera video grabber, and more expensive.
I emailed the guy who makes these, he said they will work with any Nexus that will run a regular usb webcam. He also said they should work with multiple video grabbers plugged into a USB hub, but has never tested it. (the guy said he could make one video grabber card with 4 video inputs that would display to one screen for me though, not sure how much that would cost me)
Multiple video grabbers with multiple security cameras add up fast. So this is quickly becoming the most expensive option.
USB Webcams -
Only a limited supply works with each software app. Or at least that's what the software apps say on the Google Play Store. Is this correct?
I would then need to make it waterproof to mount it outside. Maybe taking it apart and installing it in waterproof housing. But that's not this forum either.
So it seems that the best way (for me) to approach this is...
1) Use multiple security cameras or mini cameras, then scrap the nexus and use a separate video display that will show all the feeds at once.
2) Spend a lot of money on multiple grabber cards, which would be over the cost of a separate monitor.
3) Use multiple or just one USC webcam in a waterproof housing.
Ok, now onto researching more USB webcams.

I decided not to spend gobs of money...
I did plastidip a USB webcam, mounted it with a magnet to the inside of my bumper (it views through a slot in the bumper), got a usb extension cable and ran that through the firewall, to a Nexus 7 tablet with a OTG-Y cable (But the OTG-Y cable has seemed to not charge the tablet). Now I just run it direct when I want to use it.
I have tested it out once on the trail and it wasn't helpful. I plan on moving it from the center of the bumper to my passenger wheel well.
The webcam is to the left of the 3 lights in the center of the bumper.

has anyone had any further success getting multiple cameras to work?
i myself have a rca rear camera installed, using easycap viewer, and also using a android head unit usb camera in conjuntion with the app usb camera by shenyao china in playstore for dashcam, but im having a dam hard time getting them to work in conjunction, as with the usb camera app, i can background record from the front usb camera, but if i then engage reverse, easycap viewer opens but just boot loops, so im now looking for maybe a hardware solution to switch cameras by external means, maybe relays, but im no electrician, and cant find any info if this would be possible, was thinking just using relays of some description to switch the power on an off, when rear camera is initialized relay will cut power to the front camera and vice versa.
Does this sound feesible?? if so what relays would i need?
was looking at some of the auto camera switching relay boxes on aliexpress, but they only accept rca connection, which is no good for my setup, front is usb and rear is rca via easycap, now i could get a rca camera for front, but then i could not use the app on the nexus 7 usb camera to background record ect ect
ive tried defaulting the dashcam to usb camera app , and the rear to easycap viewer, and like said above it just boot loops easycap viewer as the front camera is running in the background, and shows that both cameras connect and disconnect over and over
even thought about 2 easycap devices and usb cameras and i think id be in same boat, boot looping
what is very strange though is that whilst pulling my hair out trying to find a solution, i also have a wifi transmitter for rear camera, this worked poor as a rear cam due to delay/lag, BUT i could have the front camera background recording via usb camera app and also view the rear camera picture with reverse engaged without any conflict, but had to manually open the app for the wifi transmitter (wifiavin) to see the picture, which also was a pain
anyone got any ideas if a hardware solution to my problem will work, and parts and links would be fantastic

Curious on this as well. Would love the ability to create an app to open to a specific app. Both my USB webcam and frame grabber are treated similarly by the OS, meaning all the same apps can use either camera. However I've noticed my USB webcam takes priority. If I already have it plugged in and hook up the frame grabber, it still opens the camera app right to the previouslyplugged USB webcam.
I too, would rather avoid the relays, but that might be the only way.
already tried the5v relay route, worked on bench great , but not in the real situation in my car install still looping both apps, due I think to the response time of the relays switching from one device to another grrrrrr
i just downloaded from playstore dual usb camera by shenyao china, new app by developer, now I can use this app so long as it its opened 1st after my tablet loads after re awake from sleep, then selecting reverse easycap opens as expected, rear camera is viewable, then after reserse deselected, front camera is reconnected and viewable on the screen with usb dual camera app once more, works flawlessly, but its missing the auto record and send to background ect that the usb camera (not dual camera app) app can do, emailed the developer to ask if these can be added to his new app, as of yet no reply, but my fingers are crossed
edit- just had a reply from the developer and he says hes going to incorporate the missing features from the dual usb camera app, but will take a little time, happy days
I am a bit confused by your comments... you're not implying that you have to interact with the screen to switch between forward/reverse cameras, are you? That would be unacceptable for most people.
What I can tell you is I have a HIGHLY reliable solution using the relays and Tasker. Here's how I have it set up right now:
- Forward-facing/parking camera is always on. USB 2.0 IR webcam.
- When relay has UVC framegrabber/rear-view camera disconnected, Vcam2 brings up forward-facing camera by default.
- When my car hits reverse, I kill vcam2, then re-open (using rcjoycon.) This is as long as it takes for the device to be recognized and pop up with reverse view.
- After I leave reverse, I have a timer relay to wait 5 seconds to kill the framegrabber. At that same time, I kill vcam2. If I was ALREADY in vcam2 before going into reverse, I have tasker re-open the camera. Otherwise, it just falls back to the previously-open app.
It may sound difficult but it's not all that bad. Now, if I could somehow get an app that allowed me to specify a hard-coded camera mapping, I would pay good money for this.
Imagine a tasker-controllable launch of each camera view. I would enjoy this, so I could potentially record all cameras full-time, despite what I choose to view. I have a feeling the tablet would drain awfully quickly while recording, and a dedicated dash cam might be more realistic. I really do like the idea of a hidden dash cam though, that cops/criminals might not notice.
I offset the unavoidable drain on my N7 by using yet another timer circuit. When my car turns off, the tablet stays powered for 30 minutes. I detect the loss of power through my rcjoycon, which tells tasker to go into airplane mode, and gracefully shutdown what it can, then kill the rest, and turn off the screen properly. With this setup, I have no issues. I am considering installing a switch to allow the tablet to have power 24/7 for when I am away for extended periods of time. Since I leave my car on a battery tender during those trips, it could be handy to have potential connectivity to the tablet over Wi-Fi. (Just thinking out loud.)
I just wonder if anyone has setup a front dash camera with RK3066/RF3188 head units. What application do you use to to record video from USB front camera in the background? How do you configure this application to launch automatically on boot and start recording immediately in background?
Thanks.
I have set up some USB cam apps. Right now I'm trying to get composite IN to record, but. So far "CaroO Pro (Dashcam & OBD)" has worked out the best for me. All of the settings you're asking about are easily located and configured in the app. I can have it start with movement/when my car starts/when I tell it to. It also has the option to run in the background. The other feature it has is a floating widget if you like to either see your car information. Or to take you back into the main app. Another nice thing about this app is the it connects to your bluetooth OBD adapter if you have one. Giving you a lot more information if you are looking for that sort of thing. My second choice is "AutoGuard Dash Cam - Blackbox". It does not have as many bells and whistles as CaroO, but it gets the job done. All other apps I have tried have been more of a hassle to use and set up. I would suggest trying free CaroO trial and seeing what you think. I am not sure if this helped at all, but I will be here to answer any other questions if you have them.
Has anyone got this working?
I have an Eonon G2110z head unit running KitKat and am trying to set up a dash cam. I have tried a "video in" camera (which i'd prefer to use) and a usb camera but all the dash cam apps I've tried ( about 10 I think) say they can't find the camera.
Is there any way of telling Android that the video in is where it expects the phone camera to be?

My USB camera works perfect and almost all apps recognize it. It's one of those board cams they usually use with Raspberry Pie/Arduino. It seems for the best results to look for a UVC compliant USB camera. I am not an expert in any way with these standards. But they seem to be highly compatible with Linux/Android due to them only needing to run off of a generic driver like thumb drives/external drives.
As for the video in/AV/RCA type, I still have not figured this one out :/
*A not much help rant that can be ignored: I did get an image to show up from my dash cam using a dumb/convoluted way. But it would always freeze. The flow was: micro HDMI on dash cam to standard HDMI to an HDMI digital to analog RCA converter. I have also tried the 2.5mm AV out on the cam to RCA. I think it was the same result, but now that I write this I want to go try again...
Sorry I am not much help. I hope you get this figured out. If you do, I would be forever thankful if you shared your results
I'm currently using Daily Roads with USB camera usually sold with those headunits. Problem with this apk is that it can't save last recoded file (when you switch ignition off). Can you confirm that carO pro saves last file properly?

Many thanks for this, I'll see if I can grab one of those UVC compliant cameras.
It seems to me that the apps just look for what android presents as the phone camera- maybe the trick is to get android to think that the av is the phone camera?
AV plays perfectly on the screen when I select the video player.
I used the DailyRoads app with a Logitech USB camera with decent success. I had to use another app to auto-launch the DailyRoads app on bootup. The only issue that I had was the camera picture seeming to get too bright or too dark in some situations. Manually stopping and re-recording the video seemed to fix the picture, but this was not ideal.
Since installing my new headunit, I'm going to give some other apps a try to see if the problem lies with software or my camera. Thanks for the suggestion on CaroO, I'll give it a shot.

Sorry for the late reply. I meant to check that night. I tested it twice with car0. Once turning the car off and letting the head unit sleep. Then turning back on right away. And again but let the unit fully power down and boot up. Both times Caro0 saved the videos perfectly fine.

That Caro0 app works well but doesn't "Autoload at start-up".
I've installed a basic app that autoloads Caro0. Autostart - No root
In settings menu it only gives me option to save video to internal memory, Anyone any idea how to change from within the app?.
What USB cameras are everyone using? I want to pickup a cheaper one to test and see if I want to run a dash cam.

I have no problems getting Caro0 to auto start. It'll open the app back up when my unit boots if that was the last screen I left it on. Or I have the setting checked to auto start once I begin to drive. I will have to look where my files are stored. I remember having issues with this too. I'm pretty sure I have them recording to a flash drive now. I will check.

This is the camera I am currently using. I had a friend use their 3D printer to make a case for it. Although, no matter what recording app I use I everything is too dark. It might be just the camera, but I'm looking for a way to make the overall image brighter without being over exposed. I think I'm just going to buy another soon anyways...
Hi guys!
Any luck with AV IN (RCA) video recording from back/rear/reverse camera? I have a Joying rk3188 JY-131 unit but not any look. The device coming with 2 cams, front\DVR is USB with night vision, the rear is analog camera. The front camera is not very good because IR LEDs working continuously and that make the video and picture quality very bad at day light Some suggestions to fix that problem?
I had an android rear view mirror and it can recort simultaneously with front and back cameras. The program is FireEye.apk, i tried to install a different versions at my double din, but no one work.

Hi wigglitz!
Any progress recording the brightness? I just ordered the same cam for the same purpose...
Could you post an image of your cam housing - or even better post the 3d printer file?
I'm using USB and have mine as a front camera (front grill) for curb stops mainly. My car sits low. Using the default DVR app as well. Works beautifully. Found a weatherproof usb cam specifically for it too, since most dvr cams aren't weatherproof. I love it!

I like the one that carjoying sells. I did not buy from them but have the same model.

It works great to attach to the back of your rear view mirror because of the shape of the body. I have mind there and the wires go up into the trim and you can't even see that it is there.

I connected a Logitech C910 webcam to my head unit instead of the crappy low-res camera that came with the unit.
Now I'm trying to find a decent app that will record in HD and save the files to an external SD card.
Autoboy works great, great video quality, but doesn't give me the option to record to the SD card, therefore it's useless for me.
CaroO doesn't seem to work at all with the C910, it connects to the OBD, but doesn't show the video (failed to initialize)
The stock Car Record app saves to the SD card, and sees the C910, but doesn't record in HD
Any suggestion for an app that will do what I want?
The above video is my review, i have it working great with my ownice c200 headunit. the usb seems to register that to the iPhone that it is a CarPlay device. the CarPlay UI apparently is stored and sent from the iPhone its self to the usb dongle and then sent to the android app. the app then sends touch and audio commands back to the usb dongle and then to the iPhone.
i can send photos of the internals of the device to any one who wants and a link to the APK.
MOD EDIT: removed email address and mention of selling head units. XDA is not a place to make money!
great !!!

First Step: updating the CAR PLAY USB DONGLE
Plug in the car play usb dongle on the PC, copy the "update.bin" file under the root of the dongle, no extra file folder and no any operation, just wait for 5 minutes, it will be quit automatically after updating, then pull off the USB dongle.
Second Step: Uninstall the old version ZBOX softare from the car audio, then intall the new one, then it will be ok to work.(With the new APK in the attachment and follow the manual)

The issue you are experiencing with the zbox having 'stage-fright' has to do with the power requirements of the zbox device. Some USB bus' don't provide enough power (or borderline) so functionality is intermittent. If you use a powered USB hub, that provides additional power to the USB ports, you'll have almost no issues.
I have connected a y USB adapter.
Has anyone tried one of these on a PX3 RK3166 head unit?
I have one but cant get it to work.
It connects to the apk but wont connect to the iphone.
Tried the update to firmware and apk, still no joy.
Not sure if i have a faulty dongle or it's a compatibility issue with these head units.
Alibaba seller suggested not enough power on head units usb?
I have the same problem with one of these.....
I have tried three android units now and I still can’t get them to work....
Android 4.4 it says its connect but the iPhone just shows as not found....
The other two are both 6.0.1 and the zbox just shows connecting all the time!
If any one has any help it would greatfully be received..
Or for that matter any software updates.....
Mine is showing apk: 2.1.0
Zbox versions: 2.1.0
Many thanks and kind regards
Mine works and I have a px3. I updated the device and installed the latest zbox app before I tried it. I would try swapping out cords and making sure they are certified by Apple. The only issue I have with mine is that it cannot be controlled from the steering wheel.

I use a second usb-plug and a y-cable to provide sufficient power to the device.
What do you guys do with regards to phone calls? My phone is obviously paired to the head unit via Bluetooth, so whenever I get a Call, it jumps out of CarPlay/zbox to the Stock phone interface, however the phone still transmits the audio to carplay and not via Bluetooth by default.
How any of you solved that problem?
If you are using CarPlay why do you have Bluetooth paired? Every car I've been in with CarPlay diconnects the phone from Bluetooth.

I have an Eonon GA7157 running a:
CPU: Allwinner R16 1.6GHz Cortex A7 Quad-Core
RAM: SAMSUNG DDR3, 1GB
Storage: 16GB
I have tried App and Firmware 2.x and 3.x. No joy. All I get is "Connecting" when the usb dongle and app is started. It never gets passed this "Connecting..." stage. USB devices like keyboards, mice, USB Flash drives, and even video camera work fine on this headunit. The Zbox Z1 and an OTA tuner don't work for some reason.
I did some more troubleshooting and found out the following: The dongle works perfectly on my PC running Remix. I also tried it on Samsung Table A; on this one, same symptom as the head unit, so I tried using an OTG cable and what do you know, it worked perfectly.
Therefore, I have 2 possible explanations: The headhunt's USB cable needs to be hardwire as OTG or Eonon somehow has decided to block certain type of USB devices that request data asynchronously. Why? I have not clue... I wish I could disable this flag in the OS, but I have not clue where it can be done. My headunit is rooted, so it should be possible in theory.
Hello, could you post pictures of the internals? I'm very curious what's inside the lil dongle. Also: do you still have some of the dongles? haha

Hello guys!
I am looking for Android car player for my car. I need 1Din player that have removable faceplate/screen for anti-theft reasons. By now I found only 1Din players with motorized screens that will suit my needs. There is an option like these from Joying with detachable screen but it looks too hard to do it every time I get in the car (clips, cables etc). Other requirements that I need :
- Fast processor and 2GB RAM.
- At least 2 USB's on the back - I will connect external DAC, USB camera and HDD so maybe 3 USB's or option to connect USB hub if they are only 2.
- Well build unit with good and fast factory software without bugs.
- The other requirements that I need most probably will be present because I did not see a player without them. (GPS, SWC etc.)
Can you help me with the choice?
Thanks!
I have an Android Head Unit (Android 7), with a dashcam connected to it via RCA / AV-in. The dashcam itself is managed via an app on the phone. However, I would like to be able to view the actual live videos images of the camera when driving. (I do not need a recording function, because the dashcam already does that on an SD card.)
I have been searching for an app, but cannot seem to find one. All the dashcam apps that I tried are expecting the head unit to connect with the dashcam via Wifi; instead of via the RCA/AV-in cable.
I know for a fact that the Android unit is correctly receiving the dashcam images, which can be seen when parking assistance is activated: the backup-camera image is shown when in the car is in reverse, and the dashcam image is shown when in drive.
So now I just need an app to view the live dashcam images at any time.
Any suggestions?
