 From what I can determine from Garmin's own description/specs, it appears to 
only have a USB interface.

There is no mention of a classic RS-232 serial port (required to connect to a 
Kenwood), nor any mention of FMI support (that allows the USB interface to 
"morph" into a serial port when a special cable is attached).

Note that USB client devices (like this Garmin) CAN NOT be converted to serial 
with the usual USB<-->serial dongles.  USB client devices can only link up with 
a computer-based master (a.k.a. "server") running appropriate device-specific 
driver software.
