Well, I was working on a myriad of issues yesterday. I unhooked the battery at one point, and when I put everything back together, I'm now getting a GPS logo in the upper left corner of my navigation with a red line through it. According to the book, this means GPS is not available. I tried restarting the navigation back to factory settings, but still there. I tried doing a search on here but couldn't find anything. Any ideas? Thanks.
