I just got my version 8.0c disc today and I'm curious about the difference between this and 4.0c. Is there a way to verify this is the version it claims? I thought I read somewhere that the graphics had changed at some point, although 8.0c looks similar, no grand change in the display.

The DVD should state what version it is. Typically the updates just update the maps for new streets and roads. One of the earlier version did update the software.

other than roads being updated, I don't think GM is going to spend any time/money updating our head units. it's a shame when you have a whole computer in the dash and are stuck with 1995 tech...

Is there a way to tell what version is installed?

The label on the nav DVD says which version it is.
