Are you getting that insane switching between 'no satellite data' and the signal strengths and locations?

Yes. That's why I went to the trouble to make the animated GIF of the two photos, so you could see exactly what it looked like.

So I guess my interface is WORKING (woooo!) because that's the satellite strengths screen, it switches to "no satellite data" almost immediately, and I also DO see coordinates when I toggle them on.

So if you hadn't gotten proper coordinates from the GPS unit, there would be "nothing" when I toggle coordinates on?

Do these look like they would be accurate if they were last coordinates the receiver might have gotten?:

Should have been somewhere in California.

Okay, now to go install ActivePython and mess with loading some routes.
