Happy to help.

All you will need is to replace the Nano cable with the Powerflarm cable.

I recommend getting the V7-GPS-PFCORE cable with the DB9 connector for the Power flarm. This will leave the RJ45 port on the Powerflarm available to connect a Buterfly or Flarmview display.

If you are handy with a soldering iron, you can make you own cable with the pinout above for the V7 end and the details in the PF manual for the PF end.
