It's not allowing me to change it from 76 to anything else, when I try to set it to 87.5 or 88.1 or any other frequency other than the 76 it's set at, it gives me the 'unable to use FM transmitter'. So, it is stuck at 76...and my car radio doesn't go that low :-( btw-Thanks for your help with getting the binary copied over, I do appreciate the tutorial as I start to get more familiar with xterm. I'm sure there'll be a way to figure this out, if not, it'll be fun trying With your help on what the commands mean, I was able to revert back to the original binary without an issue.
