GPS and Compass on Omnibus F4 V6 wiring

I have read through this post, but I still have one question. To use the RX3 and TX3 for the GPS, do you have to solder to them or does the GPS plug work just need to set up inav correctly?

I appreciate the help.
One additional question. Which direction on the board needs to be pointing forward, or does it not matter?

i always solder gps (better connection). forward on board is when USB is on top and on right side

Thank you. That is what I was looking for.
