In addition to Kai's info, also note that the radio's USB controller can
either connect to the SD memory card or the TNC/radio, but not both at
the same time.  Menu items 98x.  Under Windows, you may need a USB
serial port driver too; free download from the Kenwood site.  I know
it's needed for updating the firmware over USB. 

I prefer to use Bluetooth and my cell phone for APRS, using either
APRSDroid or APRSISMO.  This is wireless, after all, and having a wired
interface to a handheld radio is just annoying.
