There's a thread here on doing that but apparently many people aren't very happy with the company that provides the function. Search this forum for 'navtool'.
The other solution is Naviks, which I used to have and sold to another owner here. But he is having problems with it now, so I'm not really sure there is any true long term mirroring solution from aftermarket. I'm still crossing my fingers that someone will attempt a 18+ head unit swap!
So back to the Naviks not working again. The unit itself or HDMI module must be no good. I think I am done with these mirroring solutions, not worth the hassle and safety issues. If we see some more Android Auto reviews on Navtool I'll get that. Otherwise live with the factory system for now
Back to the mirroring options:
Got for a test following cheap tools:
1. Mirascreen, can mirror android based devices over wifi
2. hdmi -> RCA converter
got it connected to front RCA and it can mirror my phone to top display, when transmission is in parking. Switching to drive, image is blocked and I'm getting "please park" message.
Is there any option to unblock front RCA and have a possibility to use them while driving?
