I put a post like this in another Thread but I think is better to create a new.
I want to install a tv tuner (not original) in my RNS510. I know that if I have an original Tv Tuner it works we only have to program the can gateway to check the tv tuner. But with a non original if we do the same programming we have an error on gateway and the Tv option in RNS remains grey (disable). I know that the video input is RGBS and I can connect it (in the same way as the reverse camera) to the RNS510. When I put the reverse gear I can see the tv tuner image, so the RNS understand the signal. I think that may be possible to change the firmware to enable the TV (AV) input with or without the original TV tuner. Does anyone know to do that? Does anyone have the firmware source?
This is a possibility but it is not cheaper. I have a tv tuner with rgbs output so I only need to enable the TV option.
If we put an interface it write to the can network and say "the tv tuner is here" but when we try to connect the tuner it retrieve an error. We fool the cangateway.
If we change the RNS firmware there is no problem, we don´t change the can network nor the cangateway. I only need the source to understand how to do the enable but I think it is not easy to find the source.
