Dear,

I want to put TV tuner , Dvd changer, Rear Camera.

-Tv-tuner has 3 slots (1 Video, 2 Audio)
-Dvd changer has 3 slots (1 video, 2 audio)
-Rear Camera has 1 slot (1 video)

But my interface as picture it has only 3 video input + 1 IR Input. (Number5 as following picture)

The manufacturer said " you have to put both of Audio(Tv-tuner and DVD Changer) by using Y-connector put into the Aux Audio.

Q1. i had done, but it is doesnt work..
Q2. what is IR input use for?? If it s useful, where should i add it??

Thank you for you all

 

I m not sure that u guys understand what i want to ask or not? Please inform me, my english is not good.

 

i have attached file "the manual" to you. The manufacturer did not talk about the audio selector (DVD, Tv tuner)..
