Alright, I have a much clearer understanding of Xport now. The GPS and Iguidance were giving me problems when testing them on my laptop, but I installed on the actual carputer (as of this post, not yet installed in the van). Iguidance auto-detected the GPS at first, but still wouldn't zero in on my location. Then I auto-detected it again, but it wouldn't do it that time. So I tried Xport on the carputer and it instantly fixed the problem. I am hoping this will permanently fix the problem. Thanks everyone.
