Low-level console tf700t - Asus Transformer TF700

Hi, Guys
I found some interesting info while preparation of my device: we can use UART to get internal boot console.
Remove the screen
Remove black film from motherboard
Connect your USB-UART board:
GND -> GND on tf700;
RX -> TX on tf700

Now you can see all boot process of tf700 device. I can't find RX on tf700 - but you can try other pins.

Does the TP have an external GPS Antenna connector?

I see two mini coax type ports when I take off the back of my CDMA touch pro.
Does anyone know for sure if one of them is an external GPS antenna port?
The two ports are shown here:
First one is in the top left corner of the image. Second is on the bottom middle of the image (directly below "contact for main speaker")

identify this 16 pin socket

I found a 16 pin socket on the motherboard of a tablet. I think they're called 16 pin dip sockets?? Can anyone identify this for me. I'll try post a pic soon, but right now I'm curious if they're common and are for a universal purpose. I remember when I was a kid, I modded my original Xbox by soldering a chip onto the motherboard using a socket that looks almost identical to this. Any ideas??
