THANK YOU to everyone here, especially esox07! I thought I had a bad GPS unit, so I bought another. When it came in, I had just read about the "hack" of flipping the circuit board to get more accurate location data. So, I did that before I installed the second unit. No GPS on the second unit. I was bummed. Figuring that I'd accidentally broken a wire or something, I ordered a 3rd GPS unit. Installed it last night, drove to work, opened up the files in Registrator Viewer and was severely bummed when once again, no freaking GPS data. Figured I had a bad A118C. I was trying to decide if I wanted to wait for the A119C with internal GPS, or not. Then, I came here, searched the forums, and found this thread. The clouds parted, Sun shone down upon my ignorant head and kicked me in the a$$. I was using version 5.4. As soon as I updated to 6.0 that glorious GPS data showed up on the map and I am once again very happy with my dashcam.
TLDR: I was ignorant, and you guys ROCK!
Edit: I just checked some footage from last week, and my GPS unit (that I thought was bad) was actually working. D'Oh!
