Touch Screen Display

[scottellis88]

Hi all,
Has anyone ever found out how to override the touch screen display to have your own input on show but whilst in the background having radio or Bluetooth still playing?
I was able to do this with my old Land Rover Discovery 3 which had a device which interrupted the video signal to send your own input to the touch screen.

I would like to utilise the ODB2 reader on a spare phone i have to show the gauges on the screen whilst still being able to listen to the radio etc. and not just through the aux input...

Just a bit of wank factor i know but thought it may be a cool little project, especially if you could utilise phone mirroring for things such as apple/google maps etc. My Toyota Satnav system has let me down on routes a fair bit, once sending me in circles around Hervy Bay, turn left, turn left, turn left, turn left

Ive heard of someone doing a mod that uses the reverse camera input to bring up video on the screen. Audio should still play too.

Probably need a switch that activates the reverse cam trigger wire and connect the reverse cam video wire to your devices output.

No idea where I saw this.

I would think it would be less hassle to get an aftermarket headunit that can do what you want. I think some android units have apps you could download and launch to do exactly what you want to do.
