In regards to V7.5 vs. V8 I suspect it's a comfort thing were you know where to go and what to do. Please don't take that as a dig of the newer software.

Which is why I don't under stand what's happening. As you saw in my other post after flashing, It was shown they were similar files and even made a comparison.
