Heh, sorry... life getting in the way again... I start in college next month and I rolled my car on a gravel road in the middle of nowhere, totaling it.
That kinda made the project a little irrelevant, unfortunately.
As for the results of the live test... minimal success. It identified my position after about 10 minutes of sitting stationary in a parking lot, so I set it to take me home, at which point it told me, "Please proceed to the nearest road."
I made it all the way home, with the box thinking I was sitting in that parking lot the whole time.
But, for the record, it does work... just not as fast as it needs to be. One of these days I'll start from a Gentoox Pro install, go over my soldering job (I think my USB port might be failing) and try again.
I'm just more than a little tied down at present, especially with everyone I know shoving xboxes in my face to mod or repair. I think it's about time I started telling them to piss off and learn to do it for themselves.
