The rearcam signal will be converted via AVtoHDMI converter, the oem pic from nav module will be converted by module like GONBES8200 to HDMI.

So i'll make a new pcb layout that will fit into the tv module. Maybe i'll find the blue and the white connector to solder them on the new pcb.
You shouldn't disrupt your current board/design! This TV motherboard idea is VERY big.

I think you would need to have a microcontroller, to emulate TV module (IBUS device 0xED). And CVBS->RGsB converter for reverse cam and socket for possible DVB-T2 module. It's very complex and maybe one year of development...
