Kenwood hasn't made   an external auto tuner  in a long time.  Here is a 
link to Universal Radio's page of discontinued tuners:

http://www.universal-radio.com/catalog/hamtuneD.html

Look under "kenwood" and see what they used to make.  Any tuner made 
today that will interface with the 6 pin molex on the  recent Kenwood 
radio's will emulate the command set of one of these discontinued 
tuners.   I think it was the AT-230, but won't swear to it.

Not sure what tuner you have now, and  don't know what your needs are 
that may require something else.
