Honda original aftermarket works in forward too, only doubt is if it deactivate when the car is moving for safety purpose, as happens in many other cars.
I tried the way described in how-to on this post but the matter is that the navi goes crazy when u trick the car thinking that reverse gear is on. Since i didn't find any way to solve this problem i went to the official solution by Honda.
There is an official aftermarket adaptor to have video input on the navigation screen, plus there is a DVD player and a TV tuner, but is quite expensive. Is made by unicars (but they sell this item only trought honda dealer) and it provides only video, not audio.
The only adapter costs €350 and it should provide a composite input on RCA and, for safety, it should switch off as car goes faster than 10 Km/h.
I don't know much about techincal info of this product. I was questioning the guys made it but, probably they couldn't answer due the exclusive with honda dealers.
Btw this product u show me works on european Civic iPilot?
Ok i saw it today. Basically is a Y cable with male/female connector on one side and DSUB (VGA??) connector on the other. Then this cable is connected to the Adaptor that comes out with a couple of RCA Video in. Buttons to change brightness, reset, and selector of video input.
This adaptor "should" be connected to handbrake, but the reseller told me that he will kindly "forget" to connect it.
If someone was investigating it there are bright evidences that the display works with VGA input.
Later i will post some photos (not clear unfortunatly).
