Mini-iOSD Problem!

[Crank]

I've been working on my Mini-iOSD problem for the last 3 days.
I have a P2 Ver. 1.0, Black Pearl monitor, 600mw transmitter. I get a blank screen. No video or OSD info. If I run the camera video direct to the transmitter, I see video. I replaced the video in/out cable to the Mini-iOSD. No dice. I've checked my wiring over and over again. My question is my NAZA. I don't see the V2 printed on the NAZA label. It just says NAZA. See attached picture.
I'm also going to add the BTU and Data ground station. If my NAZA Version is the problem, I may be in bigger problems.

did you make your own cable or did you buy a pre-made cable that connects the mainboard, iOSD Mini and transmitter together?

"if I run the camera video direct to the transmitter" - do you mean USB from the GoPro straight to the Tx, or do you plug in a Zenmuse gimbal and get video signal from the Phantom mainboard?
