It's me again haha. I have a question. I got rid of my CF-52 that had a working wwan. I'm putting another together but can't get the gps to work. It is a MC7700 att 4g lte one. I had one that came with a gobi2000 and the black wire was on MAIN and the white on AUX. Then I got another with a gobi2000 and the black wire was on AUX and the white on MAIN. So now i'm confused. I tried to get panasonic to help but they can't/won't. Anyone have a clue which wire goes to which? Thanks! Justin

Does this help? WWAN not shown. This is the dummy also called upper bios I think. I don't know why.

WWAN antennas in MK1 are identical. Some of the later antennas on other units/marks have AUX/GPS label on one of the antennas. To be really sure necessitates splitting the lid.
