Need help with Brainiac mk2 tablet audio and backup camera

2011 Nismo#91

I am guessing you have the electronics add on? I got rid of the electronics and just got a powered USB hub and get power from the 12v lighter on the passenger footwell. On mine the audio jack on the tablet used to go directly to the amp, now I use a AudioQuest Dragonfly usb audio stick for the output to the amp.
As far as a backup camera, your pretty screwed if you want it on the tablet. It is possible but options a limited and not great. I was able to get it to kinda work with an EasyCap USB 2.0 Capture Card and a typical backup camera and the app "USB Camera - Connect EasyCap or USB WebCam". But I threw all that out because by the time the tablet booted, the app loaded, the camera connected, and finally the video displayed I could have been where I wanted to go. Solution, I wanted a dash cam anyway, was to get a rearview mirror dash cam and back up camera in one, any 100-150 dollar one would be good, mine was a VanTop brand but they are all the same as far as I can tell. As far as steeringwheel control input, ugh. There is a way but it isn't easy. You need to take the resistive inputs and wire it up correctly to this, RcJoyCon CPJexc or CPJexr types should work, and connect that to the USB hub. It can be programed to receive resistive inputs like those from our steering wheel and be programed to give usb keyboard outputs. So you can have your volume up key work just like a USB keyboard with a volume control. Its a S.Korean board and has no documentation that I could find to help. I have two boards slightly different but haven't put in the effort to figure out how to get it to work, but it should.
Talking with Brainiac was while very polite, unproductive, they offer no solutions besides "others are able too so it is supported".

There is a way to get around the steering wheel controls, simple get a Bluetooth device with a pause/play/next and mount it within reach their are a few battery power ones thy make for cars and bikes that should work well.

Thank you for the quick and detailed reply. So I hope you don't mind but I took a look at your profile because your Z looks super nice. It says that you have a different head unit. Do you still have that one or are you using the Brainiac? I know other ones are easier to configure and setup so I could opt for that as well. I do have the electronics kit but just some questions. So you have tablet aux going to the dragonfly and then its plugged into the usb hub? Then the tablet is also plugged into the usb hub? Other than that it seems simple enough. The only thing that i see going for this tablet versus other head units is the look. What do you think about using it versus others?

Thank you again I really appreciate it.

I don't mind, I haven't updated it, I'll do that later. The tablet is sending audio data to the dragonfly via the usb-C port & hub. The dragonfly audio jack goes to the amp. This did not work through Workshop 12's electronics even though "it should" according to them, I have many guesses as to why but I don't know for sure. Yes your just pretty much buying a nice looking set of plastics from them.

This has helped me a lot. The RcJoyCon is exactly what I needed, but it's expensive.



I could never get audio and video working at the same time so i gave up on that effort. I tried multiple brands, but every time the video converter is inserted, my dac gets disabled so i gave up.
