I recently crashed into a tree branch that sent my Phantom 3 4K tumbling to the ground upside down which broke the GPS module.

  

So looking around I see I need a  G173  ... which seems to be the same GPS module used in P3 Pro and Adv...

  

  

Anyone know if this is the right GPS for my P3 4K?  (I've heard there are different internal chips used for different Drones)

GPS mode for P3 4K is different from P3 Adv and P3 Pro.
Sorry for your crash, to ensure the performance, it would be best to send it in to our service center and get it fixed.

I know this is an old thread but my P3 4K has the G434 GPS module ?? My app shows "GPS unconnected" and will not fly ?!
