The GPS is horrible! I've been outside and had it take as long as 8 minutes (I timed it) to lock on. This past weekend I activated the 7-day trial for navigation. Equally bad. None of the toll roads that opened in 2006 are on the maps. RM-620, a highway that has existed for decades is wrong, it showed me driving through wilderness and kept telling me to drive back to a road. And lastly it said I was on the "I-35 access road" when I was clearly on the actual Interstate. I emailed the company (I forget the name right now) about all the problems with their software. I'm very disappointed all around with the GPS on this thing.
