I have a new garmin nuvi 660. It is handsfree and also has a mp3 player. It will work with my 2002 S60 FM radio thru a built in fm transmitter but the signal is very staticy.

There is a mini jack socket on the 660. So how tough is it to connect a direct fm modulator to the s60 radio.

I do not have a clue as to where to hook it up.

Any help?
