How to create a radar system with Oculus DK2 using Unity 5?

Hi, I'm trying to make a game for my University Project for Oculus Rift DK2. I am using Unity 5 Pro. I have searched online tutorials like-

They add a separate camera called Radar Camera placed above the player and only renders specific layer that i would have stated. Also the radar camera would have a depth of 1 so i can see them radar camera over my actual camera. Fairly Simple. My problem is when i try to replicate the process i just can not see the radar/radar camera. Is it because in the tutorials they are all using FPC etc and they have only 1 camera where as the Oculus Rift has 2 cameras (1 for each eye)?

If someone i can help me figure out how to create a simple radar system for the Oculus Rift that would be really great.

Thank you for your help.
