Phantom 2 vision plus v3, gps module question?

[Waltolaihi]

Hi there:

I want to buy a new gps module for my phantom 2 vision plus v3.

Which part should I get? What is the part number? And, if possible, where I can find it?

The reason is that I want to modify my gps module using buzzcam gps modification, which includes new 4mm gps patch antenna and shielding.

I want to do it on a new gps module instead of damaging the existing one

Thanks in advance
