I bought 2 of these apparently... and don't need the one...

I tested it, it does work in my 09 Tahoe...

does anyone else have 5.0c. I had 5.0 and it was 2 disks, this is just one disk... my 4.0c was one disk as well.

I was hoping 5.0c had a firmware update from my 4.0c, it does not...

 

does anyone else have this?

I had 4.0c and when I went to 5.0 it was a pretty noticable change, but 5.0c wasnt that much of a change... my home and work (both new buildings) are still not on them...
