Are you saying that the GPS module - the bundled MFD higher accuracy

No, I am saying it matters little what GPS you buy ($15 one or $120 one), they all have about the same accuracy just some a better suited for certain conditions and some will get a lock faster than others.

In the end it won't really matter what GPS unit you use on the AAT as you typically have at least 3mins to wait for a solid lock from the GPS on a cold start, after that it won't make any difference as you are not using the GPS to try and hover on the spot.

In that case, why pay more?
Have two systems are better than one
And the number of satellites more

Comes down to what you are using the GPS for, if you want to hold a position on your multirotor (say in loiter mode or one of the other various FC position hold mode names) then you want the GPS to be working out where it is as many times a second as it can and be telling the FC where it is.

EDIT: Also both your pictures show the GPS was only generating its 2D & 3D fix from 10 sats, not sure if the picture was meant to show that one was using more sats then the other?

The V5 doesnt use audio anymore like the older versions just video signal to track.

I think the v5 driver can still decode audio signal, mine still function with teleflyOSD (audio only)
