Yeah, Butch. Think about that "factory mod" is that you have to purchase the
module from some Kenwood dealer as the company won't sell them to individuals
and then you have to send the radio and module to Kenwood for the modification.
They refuse to let out exactly how its done and its a pretty complicated set of
wiring that comes with the module.
