Yes I have searched the forums...

I know you can buy that thing for alot of money to plug into stock harness and have backup/navi/dvd control.

I'm connecting my stock navi/dvd from totaled 04 g coupe to my 03 sedan with the ac/radio problem, idc for the navi because it's 10 years old and my phone can do better. And I don't want to buy that module for 300 bucks on my 11 year old 2300$ G(which I still love). So my question is if there's any way to directly connect a hdmi/red white yellow/ wire to the stock navi screen from my 04 G?
