I think I was trying to download things I didn't need on my computer, which has Windows 7. I just skipped that stuff and downloaded the update to my sd card, and uploaded the updates to my units. It went very smoothly.
I'm relatively clueless when it comes to computers, and I'm pretty confused about what I need to do to view recordings on my pc, but I have a friend with HBs who's a bit of a computer geek, so I hope he can help me out on that. If not, I'll start a new thread.
I also noticed what appeared to be some interference on the left side of my si my first time out, which I think might be caused by the metal screen over my livewell intake. But, that's another topic as well.
