I've looked online and I haven't had much luck but where can I find the programing software for the radio at? I work for the local sheriff's department and I have this radio in my unit and when I have anything changed on it I have to wait on the service guy in town to free space to get to my car, but I was just going to get the software and do it from my computer at home so I won't have to wait anymore. Also what cable will I need? I have one that I think will fit but I'm not sure what end I'll need, I haven't taken the radio and tried looking for a plug, I just bought it and had it installed. Thanks for the help guys.
