This is super quick and easy. I won’t take credit for this mod, however I would like to put it down in writing (I prefer looking up how tos on web pages since video tutorials are slow). The video (which I didn’t do) of the mod can be found here.
I used an Eachine ProDVR on these goggles. I have another pair of goggles in which I used an HMDVR and connected it in the same way shown here.
Remove the 4 screws on the front monitor part of the goggles:
Carefully open up the case and locate the video receiver (large metal square).
Find a good spot to drill a hole so you can run the wires between the receiver and DVR.
Connect the wires to the video receiver as shown:
- Red is + (goes on 5th solder point from the top)
- Black is ground (goes on 1st solder point from the top)
- Yellow is video in (goes on 2nd solder point from the top)
Put it back together.
