I believe it works with all phantoms,
Super easy install
( go to flytrex.com ) they have a nice tutorial video )
It requires you to OPEN the phantom up, Unhook
GPS cable from main circuit board, plug in NEW
cable ( you buy seperatly from flytrex ) 1 wire with
( 3 ) ends on it, 1st end into GPS plug on main circuit board
( the one you just unhooked GPS from ) 2nd end you replug GPS
Into this new slot ) the GPS plug you unhooked above,
And the 3rd and final end , plugs into flytrex core 2!
I velcro'ed mine to phantom belly, required me to ( disassemble flytrex plug end )
To allow wire to pass through landing gear ) then reassembled plug back together!
Some people mount it inside, or cut a hole for the wire to pass through, ect.
Here isy install :
Take care, Fly safe.
Hope this helps!
